Filed on November 4, 2005
File No. 0-31283

Dear Mr. Green:

      We have limited our review of your filing to those issues we
have addressed on our comments.  Where indicated, we think you
should
revise your documents in response to these comments.  If you
disagree, we will consider your explanation as to why our comment
is
inapplicable or a revision is unnecessary.  Please be as detailed
as
necessary in your explanation.  In some of our comments, we may
ask
you to provide us with information so we may better understand
your
disclosure.  After reviewing this information, we may raise
additional comments.

      Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or on any other
aspect
of our review.  Feel free to call us at the telephone numbers
listed
at the end of this letter.

General

1. Please include a section describing interests of certain
persons
in the forepart of the document describing the benefits that
officers
and directors receive the transaction and any conflicts of
interest.
We note, for example, that the Voting Agreement provides for board
designees. Also provide this information in the Summary section.
See
Item 5 of Schedule 14A.

2. In addition, under the Voting Agreement, Delta has agreed to
vote
its shares a certain way.  It is not clear, since the asset
purchase
agreement has not been completed yet, whether Delta already owned
shares of your stock or whether the stock ownership is a result of
the shares to be issued in the asset purchase agreement.  Please
clarify and provide appropriate disclosure regarding the resulting
conflicts of interest.

3. Please provide information about Delta, as required by Item
14(c)(2) of Schedule 14A.

4. We note that you have 50 million shares authorized, that you
will
have approximately 40 million issued and outstanding after the
issuance of the warrant shares, and that you have shares reserved
under your stock option plans. Please advise us if you also plan
to
seek shareholder approval to amend your articles of incorporation
to
increase the amount of shares authorized.

5. Please attach all material agreements to the transaction to the
proxy statement, such as the voting agreement.  Also include the
full
text of the Ohio Control Share Acquisition Act. All material
agreements should also be filed with your Exchange Act reports or
advise us where you have filed these agreements.

6. It is not clear from the disclosure what assets you will
purchase
from Delta.  Please describe in more detail and quantify if
possible
what you will acquire (including the nature of the assets and the
business conducted pursuant to these assets) so that investors are
aware of how the company or its business will change as a result
of
the acquisition.  Briefly describe how this acquisition relates to
or
complements your current business.

Summary, page 4

7. Please quantify the estimated purchase price for the
transaction.

8. Please disclose whether this transaction will cause a change of
control. If so, describe any other material triggering events to
the
company, such as severance payments or acceleration of option
vesting.

9. You describe mostly positive, but not negative, aspects of the
transaction with respect to the shareholders. Please revise to
provide a more balanced summary. For example, discuss the dilutive
effects to existing shareholders and the effect of waiving the
unaffiliated shareholder protections afforded by the Ohio statute.

10. Ensure that the Summary includes the key terms of the
transaction
from an investor`s point of view.  For example, disclose the
changes
to the board.  Consider whether other aspects of your transaction
are
material to shareholders and should be discussed in the Summary.

Conditions to the Transactions Contemplated by the Asset Purchase
Agreement and Expected Timing, page 6

11. Clarify that you will recirculate a new proxy statement and
resolicit the vote if material conditions to the merger are
waived.

Notes to Unaudited Pro Forma Condensed Consolidated Financial
Information with Delta, page 17

12. Please tell us whether the acquisition of Delta Products
Corporation represents the acquisition of a business or of assets
based on the guidance in Rule 11-01(d) of Regulation S-X.  Please
also tell us the facts and circumstances that you considered in
determining whether the acquisition constituted the purchase of a
business or assets based on this guidance.  Please bear in mind,
that
the acquisition of a product line constitutes the acquisition of a
business under the broad guidelines of Rule 11-01(d) of Regulation
S-
X.  In the event that you determine that you have acquired a
business, please file three years of historical financial
statements
and interim financial statements for Delta Products Corporation.
Please refer to Item 14 of the Proxy Rules.

13. Please tell us whether the acquisition of Delta Products
Corporation represents the acquisition of a business or of assets
under generally accepted accounting principles based on the
guidance
in EITF 98-3.  Please also tell us the facts and circumstances
that
you considered in determining whether the acquisition constituted
the
purchase of a business or assets based on this guidance.  In the
event that you determine that you have acquired assets as opposed
to
a business, please tell us why you have allocated a portion of the
purchase price to goodwill given the guidance in paragraph 9 of
SFAS
142 that goodwill does not arise from the purchase of a group of
assets.

14. Please disclose the background and discussions relating to the
material ancillary agreements, such as the voting, support, and
supply agreements.

15. Please quantify the number of shares and the percent of the

to
the Voting Agreement. Please disclose the number of shareholders
and
the group or class of shareholders whose consent you solicited.

Purchase
Agreement, page 23

16. Please discuss and quantify the risks that the board
considered
in specific terms and for each of the factors discussed, disclose
how
each factor either supported or did not support your decision to
approve the merger.  For example, you state that one of the
factors
is "the presentations of our management regarding our business,
operations, management, financial condition, earnings and
prospects,"
but you do not explain how this information impacted the board`s
decision.

17. Please describe whether the Board considered the dilutive
effect
to shareholders and any potential change of control.

nature of the management-prepared documents, lists and schedules.

21. In the first full paragraph n page 26, please either disclose
the
"other studies, analyses and investigations" or delete the
reference.

shares
and the effect on existing shareholders. If not, please disclose

this will affect the fairness opinion.

large?
