                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.   BASIS OF PRESENTATION

     The  accompanying  consolidated  financial  statements,  in the  opinion of
     management,  include all  adjustments,  consisting only of normal recurring
     accruals,  necessary for a fair presentation of the results for the interim
     periods presented.  The consolidated  financial statements are presented in
     accordance  with the  requirements  of Form  10-Q and  consequently  do not
     include all the  disclosures  required by accounting  principles  generally
     accepted in the United States of America  (GAAP).  For further  information
     refer to the consolidated  financial  statements and related notes included
     in the  Company's  Annual  Report on Form 10-K for the  fiscal  year  ended
     September 30, 2004.

     The results  for the three month  period  ended  December  31, 2004 are not
     necessarily indicative of the results for the entire 2005 fiscal year.


2.   DISCONTINUED OPERATIONS  - 2004

     Microfiltration  and  Separations  Businesses  (MicroSep)  -  The  MicroSep
     businesses  consisted of PTI Advanced  Filtration  Inc.,  PTI  Technologies
     Limited, and PTI S.p.A.  Effective April 2, 2004, the Company completed the
     sale  of  PTI  Advanced  Filtration  Inc.  (Oxnard,   California)  and  PTI
     Technologies  Limited (Sheffield,  England) to domnick hunter group plc for
     $18 million in cash. On June 8, 2004, the Company completed the sale of PTI
     S.p.A. (Milan, Italy) to a group of investors comprised of the subsidiary's
     senior  management  for $5.3  million.  An  after-tax  loss of $0.4 million
     related to the MicroSep  businesses  is reflected in the  Company's  fiscal
     2004 first quarter results in discontinued operations.


3.   EARNINGS PER SHARE (EPS)

     Basic EPS is calculated  using the weighted average number of common shares
     outstanding during the period. Diluted EPS is calculated using the weighted
     average number of common shares  outstanding  during the period plus shares
     issuable  upon the assumed  exercise of dilutive  common share  options and
     vesting of performance-accelerated restricted shares (restricted shares) by
     using  the  treasury  stock  method.  The  number  of  shares  used  in the
     calculation  of earnings per share for each period  presented is as follows
     (in thousands):

     Options to purchase  1,500  shares of common stock at a price of $77.71 and
     options to purchase 77,250 shares of common stock at a price of $48.58 were
     outstanding  during the three month  periods  ended  December  31, 2004 and
     2003, respectively, but were not included in the computation of diluted EPS
     because the options'  exercise  prices were greater than the average market
     price of the common shares.  The options expire at various  periods through
     2013.  Approximately 27,000 and 16,000  performance-accelerated  restricted
     shares were excluded from the  respective  computation of diluted EPS based
     upon the  application  of the  treasury  stock  method for the three  month
     periods ended December 31, 2004 and 2003, respectively.




     Had   compensation   cost  for  the   Company's   stock  option  plans  and
     performance-accelerated restricted share plans been determined based on the
     fair value at the grant date for awards  outstanding during the three month
     periods ended December 31, 2004 and 2003  consistent with the provisions of

     2004 and 2003, respectively: expected dividend yield of 0% in both periods;
     expected volatility of 28.3% and 23.9%; risk-free interest rate of 3.6% and

8.       RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In December 2004, the Financial  Accounting  Standards  Board (FASB) issued
     SFAS No. 123 (R),  "Share-Based Payment" (SFAS No. 123 (R)). This Statement
     replaces  SFAS No.  123,  "Accounting  for  Stock-Based  Compensation"  and
     supersedes APB No. 25, "Accounting for Stock Issued to Employees." SFAS 123
     (R) requires all stock-based compensation to be recognized as an expense in
     the financial  statements  and that such cost be measured  according to the
     fair value of stock  options.  SFAS 123 (R) will be effective for quarterly
     periods  beginning  after June 15,  2005.  The  Company  plans to adopt the
     provisions  of this  Statement  in the fourth  quarter of fiscal  2005 on a
     prospective basis. The Company currently provides the pro forma disclosures
     required  by SFAS No.  148, "Accounting  for  Stock-Based  Compensation  -
     Transition and  Disclosure,"  on a quarterly  basis (see "Note 3 - Earnings
     Per Share").

     In  December   2004,  the  FASB  issued  FASB  Staff  Position  FAS  109-2,
     "Accounting and Disclosure  Guidance for the Foreign Earnings  Repatriation
     Provision  within the American  Jobs Creation Act of 2004 (FSP 109-2)." The
     American  Jobs  Creation  Act of 2004,  (the "Act")  provides for a special
     one-time  deduction of 85 percent of certain foreign  earnings  repatriated
     into the U.S. from non-U.S.  subsidiaries  through  September 30, 2006. The
     Company is currently  evaluating the merits of repatriating funds under the
     Act. The range of reasonably  possible amounts of unremitted  earnings that
     are being  considered for  repatriation  is between zero and $27.6 million,
     which would require the Company to pay income taxes in the range of zero to
     $2.0  million.  Federal  income taxes on the  repatriated  amounts would be
     based on the 5.25%  effective  statutory  rate as provided in the Act, plus
     applicable  withholding  taxes.  To date,  the Company has not provided for
     income taxes on  unremitted  earnings  generated  by non-U.S.  subsidiaries
     given the Company's  historical intent to permanently invest these earnings
     abroad.  As a result,  additional taxes will be required to be recorded for
     any funds  repatriated  under the Act. The Company  expects to complete its
     evaluation of the repatriation provision of the Act by September 30, 2006.

ITEM 2 MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS

The  following  discussion  refers  to the  Company's  results  from  continuing
operations,  except where noted. The Microfiltration and Separations  businesses
(MicroSep),  which were sold in the third quarter of fiscal 2004,  are accounted
for as discontinued  operations in accordance with SFAS No. 144, "Accounting for
the  Impairment or Disposal of  Long-Lived  Assets."  Accordingly,  the MicroSep
businesses are reflected as discontinued  operations in the financial statements
and related notes for fiscal 2004.

NET SALES

Net sales  increased  $8.0  million  (8.3%) to $104.4  million for the
first  quarter of fiscal 2005 from $96.4 million for the first quarter of fiscal
2004, primarily due to increases across all three operating segments including a
favorable foreign currency impact which contributed $1.5 million to the increase
in  sales.  On  a  segment  basis,   for  the  first  quarter  of  fiscal  2005,
Filtration/Fluid  Flow sales increased 10%,  Communications  sales increased 7%,
and Test sales increased 7% from the prior year period.

- -Filtration/Fluid Flow
Net sales  increased $4.1 million (10.3%) to $44.0 million for the first quarter
of fiscal 2005 from $39.9  million  for the first  quarter of fiscal  2004.  The
sales increase  during the fiscal quarter ended December 31, 2004 as compared to
the prior year quarter is mainly due to the  following:  higher  commercial  and
military  aerospace  shipments at PTI Technologies Inc. (PTI) of $2.3 million, a
net sales  increase at  Filtertek of $1.1  million  driven by favorable  foreign
currency rates related to its European operations,  and higher defense shipments
at VACCO of $0.7 million.

- -Communications
For the first  quarter  of fiscal  2005,  net sales of $33.5  million  were $2.1
million,  or 6.7%,  higher than the $31.4  million of net sales  recorded in the
first quarter of fiscal 2004.  The sales increase in the first quarter of fiscal
2005 as compared to the prior year period is the result of higher  shipments  of
Comtrak's SecurVision video security products,  which generated $7.1 million in
sales  during the first  quarter of fiscal 2005  compared to $0.5 million in the
prior year  period.  This  increase  in  Comtrak's  shipments  was the result of
additional  deliveries which had been previously delayed by the customer who had
required a modification of the products to provide enhanced "virus"  protection.
DCSI's sales of automatic  meter  reading  (AMR)  equipment to electric  utility
customers  were $26.4  million in the first  quarter of fiscal 2005  compared to
$31.0  million  in the  prior  year  period.  Sales  to PPL  Electric  Utilities
Corporation (PPL) decreased  approximately $11.5 million in the first quarter of
fiscal 2005  compared to the prior year period due to the  wind-down  of the PPL
contract.  Sales to PPL were  $1.0  million  and  $12.5  million  in the  fiscal
quarters ended December 31, 2004 and 2003,  respectively.  The decrease in sales
to PPL was partially  offset by higher AMR product sales to the electric utility
cooperative (COOP) market and other customers.  DCSI's sales to COOP's and other
customers  were $25.4  million and $18.5  million in the fiscal  quarters  ended
December 31, 2004 and 2003, respectively.




- -Test

Net sales  increased  $1.7 million (6.8%) to $26.8 million for the first quarter
of fiscal 2005 from $25.1  million  for the first  quarter of fiscal  2004.  The
sales increase  during the fiscal quarter ended December 31, 2004 as compared to
the prior year  quarter  is  primarily  due to the  completion  of several  test
chamber  installations,  higher  antenna  and  other  component  sales,  and the
completion of additional government shielding projects.

ORDERS AND BACKLOG
Backlog was $246.4  million at December 31, 2004 compared with $249.1 million at
September 30, 2004. The Company received new orders totaling  approximately $102
million in the first  quarter of fiscal 2005.  New orders of $39.2  million were
received in the first  quarter of fiscal 2005 related to  Filtration/Fluid  Flow
products,  $35.3 million  related to  Communications  products  (includes  $30.7
million of new orders  related to AMR  products),  and $27.1 million  related to
Test products.

GROSS PROFIT
The Company  computes  gross  profit as net sales less cost of sales.  The gross
profit  margin  is the  gross  profit  divided  by  net  sales,  expressed  as a
percentage.  The gross profit margin was 34.4% and 31.3% in the first quarter of
fiscal  2005 and 2004,  respectively.  This  increase  of 3.1% was mainly due to
higher  margins on shipments of AMR equipment and  SecurVision  products in the
Communications  segment. In addition,  the prior year first quarter gross profit
margin in the Filtration/Fluid  Flow segment was negatively impacted by the exit
and move costs incurred and the inefficiencies  being absorbed at Filtertek as a
result of operating in both the Puerto Rico and Juarez,  Mexico facilities.  The
closure and  relocation of the  Filtertek  Puerto Rico facility was completed in
March 2004.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
Selling,  general and  administrative  (SG&A)  expenses for the first quarter of
fiscal 2005 were $19.8 million (19.0% of net sales), compared with $18.8 million
(19.5% of net sales) for the prior year period. The increase in SG&A spending in
the fiscal  quarter ended December 31, 2004 as compared to the prior year period
is mainly due to the costs associated with marketing, project management and new
product  development within the Communications  segment to further penetrate the
investor owned utility market.

OTHER (INCOME) EXPENSES, NET
Other (income) expenses, net, were $(0.5) million for the quarter ended December
31,  2004  compared  to $0.6  million  for the  prior  year  quarter.  Principal
components of other (income) expenses, net, for the first quarter of fiscal 2005
included  $(0.6)  million of royalty  income  and $0.2  million of  amortization
expense of  identifiable  intangible  assets  (primarily  patents,  licenses and
software).  Principal components of other (income) expenses,  net, for the first
quarter  of fiscal  2004  included  the  following:  $0.4  million of exit costs
related to the Filtertek  Puerto Rico facility and $0.2 million of  amortization
of identifiable intangible assets (primarily patents and licenses).

EBIT

The Company  evaluates the performance of its operating  segments based on EBIT,
defined below. EBIT was $16.5 million (15.8% of net sales) for the first quarter
of fiscal 2005 and $10.7  million  (11.1% of net sales) for the first quarter of
fiscal 2004.  EBIT for the first quarter of fiscal 2004 was negatively  impacted
by $0.7 million of severance and exit costs related to the Filtertek Puerto Rico
facility (Filtration/Fluid Flow segment).

This Form 10-Q contains the financial measure "EBIT", which is not calculated in
accordance with generally accepted accounting principles in the United States of
America  (GAAP).  EBIT provides  investors and  Management  with an  alternative
method for assessing the Company's operating results. The Company defines "EBIT"
as earnings from continuing  operations  before  interest and taxes.  Management
evaluates the performance of its operating  segments based on EBIT, and believes
that EBIT is useful to investors to demonstrate the operational profitability of
the  Company's  business  segments by excluding  interest  and taxes,  which are
generally  accounted for across the entire Company on a consolidated basis. EBIT
is also one of the measures  Management uses to determine  resource  allocations
within the Company and incentive compensation.  The following table represents a
reconciliation of EBIT to net earnings from continuing operations.

- -Filtration/Fluid Flow

EBIT was $7.1 million  (16.0% of net sales) and $3.5 million (8.8% of net sales)
in the first  quarters of fiscal 2005 and 2004,  respectively.  This increase of
$3.6 million was due to the  following:  a $1.8 million  increase at  Filtertek,
which included $0.6 million of cost reimbursement from a medical device customer
related to a  shortfall  between  their  actual  purchases  versus  the  minimum
contractually  guaranteed amount (the first quarter of fiscal 2004 included $0.7
million of exit  costs  related to the Puerto  Rico  facility);  a $1.1  million
increase at PTI due to higher commercial and military aerospace shipments; and a
$0.7 million increase at VACCO due to higher defense shipments.

- -Communications
EBIT in the first  quarter of fiscal 2005 was $9.6 million  (28.7% of net sales)
as compared to $7.4 million  (23.5% of net sales) in the prior year period.  The
increase in EBIT  margin in the first  quarter of fiscal 2005 as compared to the
prior  year  period is  mainly  due to the  additional  shipments  of  Comtrak's
SecurVision  products,  as  well as the  favorable  sales  mix of AMR  products
resulting from additional sales to the COOP market, and cost reductions realized
on certain AMR components. The Company will continue to increase its engineering
and new product development  expenditures in the Communications segment in order
to continue  its growth in the AMR  markets,  and to further  differentiate  its
technology from the competition.

- -Test
EBIT in the first quarter of fiscal 2005 was $2.1 million (7.8% of net sales) as
compared  to $2.2  million  (8.8% of net sales) in the prior year  period.  This
decrease  in  EBIT is  mainly  the  result  of  approximately  $0.3  million  in
installation cost overruns  incurred on certain  government  shielding  projects
being installed in challenging  areas throughout the world, as well as increased
costs of steel and copper.

- -Corporate
Corporate  costs included in EBIT were ($2.3) million for the three month period
ended December 31, 2004 compared to ($2.4) million for the prior year period.

INTEREST INCOME, NET
Interest income,  net was $0.5 million for the three month period ended December
31, 2004 compared to interest  income of $0.1 million for the prior year period.
This  increase  in  interest  income is mainly due to a tax  refund of  lookback
interest and higher average cash balances on hand in fiscal 2005.

INCOME TAX EXPENSE
The first quarter  fiscal 2005  effective  income tax rate was 38.1% compared to
38.9% in the first quarter of fiscal 2004. The decrease in the effective  income
tax rate in the first  quarter of fiscal 2005 is primarily due to the timing and
volume of profit contributions of the Company's foreign operations.  The Company
estimates the annual effective tax rate for fiscal 2005 to be approximately 38%.

CAPITAL RESOURCES AND LIQUIDITY

Working  capital  decreased  to $154.6  million at December 31, 2004 from $165.2
million at  September  30,  2004.  During the first three months of fiscal 2005,
cash  decreased  $11.9  million  due  to the  $24.9  million  share  repurchase,
partially  offset  by  cash  generated  from  operations.   Accounts  receivable
decreased  by $8.5 million due to timing of sales and  collections.  Inventories
increased by $3.9  million in the first three  months of fiscal  2005,  of which
$2.0  million  related to the Test  segment  due to the timing of sales and $1.1
million  was to  build  safety  stock  within  the  Communications  segment.  In
addition,  accounts payable and accrued  expenses  decreased by $10.4 million in
the first three  months of fiscal  2005,  primarily  due to the timing of vendor
payments and payroll periods.

Net cash provided by operating  activities from continuing  operations increased
to $14.3  million in the first three  months of fiscal  2005,  compared to $13.4
million in the same period of fiscal 2004.

Capital  expenditures  from  continuing  operations  were $2.0  million and $2.5
million  in the first  quarter  of fiscal  2005 and  2004,  respectively.  Major
expenditures in the current period included manufacturing equipment and facility
modifications used in the Filtration/Fluid Flow businesses.

The Company has  approximately  $1.5 million in  commitments  outstanding in the
Communications  segment to further  differentiate  its  products  and to further
penetrate the investor owned utility market. This amount is expected to be spent
during fiscal 2005.

The closure and  relocation of the Filtertek  Puerto Rico facility was completed
in March 2004. The Puerto Rico facility is included in other current assets with
a carrying value of $3.6 million at December 31, 2004. The facility continues to
be actively marketed for sale.

In October 2004, the Company entered into a new $100 million five-year revolving
bank credit  facility with a $50 million  increase  option,  which  replaced its
then-existing   credit   facility.   At  December  31,  2004,  the  Company  had
approximately  $98.6  million  available to borrow under the credit  facility in
addition to $60.4 million cash on hand. Against the $100 million available under
the revolving  credit facility at December 31, 2004, the Company had outstanding
letters of credit of $1.4  million.  Cash flow from  operations  and  borrowings
under the  Company's  bank credit  facility are  expected to meet the  Company's
capital requirements and operational needs for the foreseeable future.

STOCK REPURCHASE PROGRAM
In August 2004, the Company's  Board of Directors  approved the extension of the
previously  authorized  (February 2001) open market repurchase  program of up to
1.1 million shares,  which is subject to market conditions and other factors and
covers the period ending September 30, 2006.  During the first quarter of fiscal
2005, the Company  repurchased  335,036 shares under this program for a total of
$24.9 million and has approximately  575,000 shares remaining under this program
at December 31, 2004.

CRITICAL ACCOUNTING POLICIES
Management has evaluated the accounting  policies used in the preparation of the
Company's financial  statements and related notes and believes those policies to
be reasonable and appropriate.  Certain of these accounting policies require the
application  of  significant  judgment by  management  in selecting  appropriate
assumptions  for  calculating  financial  estimates.   By  their  nature,  these
judgments are subject to an inherent degree of uncertainty.  These judgments are
based on historical experience, trends in the industry,  information provided by
customers and information  available from other outside sources, as appropriate.
The most significant areas involving  management  judgments and estimates may be
found in the Critical Accounting Policies Section of Management's Discussion and
Analysis and in Note 1 to the Consolidated Financial Statements contained in the
Company's  Annual  Report on Form 10-K for the fiscal year ended  September  30,
2004, at Exhibit 13.

OTHER MATTERS

Contingencies

As a normal incident of the businesses in which the Company is engaged,  various
claims, charges and litigation are asserted or commenced against the Company. In
the opinion of  Management,  final  judgments,  if any,  which might be rendered
against the Company in current  litigation are adequately  reserved,  covered by
insurance,  or  would  not  have a  material  adverse  effect  on its  financial
statements.

affected,  or is reasonably likely to materially  affect, the Company's internal
control over financial reporting.
