SIGNIFICANT ACCOUNTING POLICIES	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES Advertising Expenses - 178,500 78,200 Accounts Receivable, net Cash and Cash Equivalents - Consolidation Earnings Per Share - Equipment, Furnishings and Leasehold Improvements three five Minimum Maximum Fair Value of Financial Instruments Fair Value Measurement The carrying amounts of financial instruments reported in the accompanying consolidated financial statements for current assets and current liabilities approximate the fair value because of the immediate or short-term maturities of the financial instruments. The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below: Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities. The fair values of financial assets of the Company were determined using the following categories at February 28, 2022 and February 28, 2021, respectively: Significant Accounting Policies - Fair values of financial assets of the Company Level 1 Level 2 Level 3 Total Marketable Securities – February 28, 2022 $ 5,716,338 $ 151,652 $ — $ 5,867,990 Marketable Securities – February 28, 2021 $ 4,261,927 $ 301,543 $ — $ 4,563,470 Marketable Securities include certificates of deposit and US Treasury securities, totaling $ 5,867,990 4,563,470 Income Taxes Intangible Assets - seventeen twelve 192,490 181,922 11,000 Inventories - Land and Buildings forty Land and Buildings Long-Lived Assets - Management Estimates - New Accounting Pronouncements Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes In June 2016, the FASB issued ASU 2016-13 - Financial Instruments-Credit Losses-Measurement of Credit Losses on Financial Instruments. Codification Improvements to Topic 326, Financial Instruments – Credit Losses, have been released in November 2018 (2018-19), November 2019 (2019-10 and 2019-11) and a January 2020 Update (2020-02) that provided additional guidance on this Topic. This guidance replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For SEC filers meeting certain criteria, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For SEC filers that meet the criteria of a smaller reporting company (including this Company) and for non-SEC registrant public companies and other organizations, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently in the process of its analysis of the impact of this guidance on its consolidated financial statements and does not expect the adoption of this guidance to have a material impact on the Company’s consolidated financial statements. Other than Accounting Standards Update (“ASU”) 2019-12 and ASU 2016-13 discussed above, all new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence, the adoption of these new accounting pronouncements, once effective, is not expected to have an impact on the Company. Product Warranty Research and Product Development Expenses - Revenue Recognition To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: · Identification of the contract, or contracts, with a customer · Identification of the performance obligations in the contract · Determination of the transaction price · Allocation of the transaction price to the performance obligations in the contract · Recognition of revenue when, or as, performance obligations are satisfied Shipping and Handling Costs Stock-Based Compensation ASC 718 requires the recognition of the fair value of stock compensation expense to be recognized over the vesting term of such award. The Company accounts for forfeitures as they occur. Uncertainties

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	NOTE 3: REVENUE RECOGNITION A majority of the Company’s sales revenue is derived primarily from short term contracts with customers, which, on average, are in effect for less than twelve months. Sales revenue from manufactured equipment transferred at a single point in time accounts for a majority of the Company’s revenue. Sales revenue is recognized when control of the Company’s manufactured equipment is transferred to its customers in an amount that reflects the consideration the Company expects to receive based upon the agreed transaction price. The Company’s performance obligations are satisfied when its customers take control of the purchased equipment, which is based on the contract terms. Based on prior experience, the Company reasonably estimates its sales returns and warranty reserves. Sales are presented net of discounts and allowances. Discounts and allowances are determined when a sale is negotiated. The Company does not grant its customers or independent representatives the ability to return equipment nor does it grant price adjustments after a sale is complete. The Company does not capitalize any sales commission costs related to the acquisition of a contract. All commissions related to a performance obligation that are satisfied at a point in time are expensed when the customer takes control of the purchased equipment. The Company applies the practical expedient in paragraph ASC 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one-year or less. At February 28, 2022, the Company had received $ 1,168,000 5,000 the Company was utilizing $5,000 of its available credit line to collateralize these letters of credit At February 28, 2021, the Company had received $ 1,167,000 849,000 the Company was utilizing $849,000 of its available credit line to collateralize these letters of credit The Company’s sales revenue, by product line is as follows: Revenue Recognition - Sales Revenue by Product Line Twelve Months Ended February 28, February 28, 2022 % of total 2021 % of total Fluxing Systems $ 691,000 4 $ 798,000 5 Integrated Coating Systems 1,182,000 7 4,219,000 28 Multi-Axis Coating Systems 9,912,000 58 5,614,000 38 OEM Systems 2,381,000 14 1,582,000 11 Other 2,967,000 17 2,620,000 18 TOTAL $ 17,133,000 $ 14,833,000

For qualified employees, except under certain circumstances specified in the plan or unless otherwise specified at the discretion of the Board of Directors, no option may be exercised prior to one year after date of grant, with the balance becoming exercisable in cumulative installments over a three-year period during the term of the option, and terminating at a stipulated period of time after an employee's termination of employment.

The Company uses the Black-Scholes option pricing model to value its stock option awards. The assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. The expected term of the options is estimated based on the Company’s historical exercise rate. The expected life of awards that vest immediately use the contractual maturity since they are vested when issued. For stock price volatility, the Company uses its expected volatility of the price of the Company’s common stock based on historical activity. The risk-free interest rate is based on U.S. Treasury notes with a term approximating the expected life of the option at the grant-date. The weighted-average fair value of options has been estimated on the date of grant using the Black-Scholes options-pricing model. The weighted-average Black-Scholes assumptions are as follows: Stock-Based Compensation - Weighted-average Black-Scholes assumptions Fiscal Year Ended February 28, February 28, Expected life 5 8 5 8 Risk free interest rate 0.78 2.0 0.46 0.78 Expected volatility 50.73 57.13 48.88 58.63 Expected dividend yield 0 0

INCOME TAXES	NOTE 10: INCOME TAXES The annual provision (benefit) for income taxes differs from amounts computed by applying the maximum U.S. Federal income tax rate of 21% to pre-tax income as follows: Income Taxes - Income tax reconciliation February 28, February 28, Expected federal income tax $ 609,883 $ 283,052 State tax, net of federal 37,894 27,102 Research and development tax credits (101,573 ) (105,320 ) Permanent differences (179,320 ) 12,719 Other (5,253 ) 9,672 Income tax expense $ 361,631 $ 227,225 In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and projections for future taxable income over periods in which the deferred tax assets are deductible. Management believes it is more likely than not that the Company will realize the benefits of these deductible differences. Management does not believe that there are significant uncertain tax positions in 2022. There are no interest and penalties related to uncertain tax positions in 2022. As of February 28, 2022, open years related to the federal and state jurisdictions are 2020, 2019 and 2018. The deferred tax asset and liability are comprised of the following: Income Taxes - Deferred tax asset and liability components February 28, February 28, Deferred tax asset Allowance for inventory $ 69,000 $ 66,000 Allowance for accounts receivable 12,000 13,000 Accrued expenses and other 160,000 181,000 Deferred tax asset – Long Term $ 241,000 $ 260,000 Deferred tax liability Building and leasehold depreciation (169,000 ) (206,000 ) Deferred tax liability – Long Term $ (169,000 ) $ (206,000 )

Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair Value Measurement The carrying amounts of financial instruments reported in the accompanying consolidated financial statements for current assets and current liabilities approximate the fair value because of the immediate or short-term maturities of the financial instruments. The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below: Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities. The fair values of financial assets of the Company were determined using the following categories at February 28, 2022 and February 28, 2021, respectively: Significant Accounting Policies - Fair values of financial assets of the Company Level 1 Level 2 Level 3 Total Marketable Securities – February 28, 2022 $ 5,716,338 $ 151,652 $ — $ 5,867,990 Marketable Securities – February 28, 2021 $ 4,261,927 $ 301,543 $ — $ 4,563,470 Marketable Securities include certificates of deposit and US Treasury securities, totaling $ 5,867,990 4,563,470 Income Taxes Intangible Assets - seventeen twelve 192,490 181,922 11,000 Inventories - Land and Buildings forty Land and Buildings Long-Lived Assets - Management Estimates - New Accounting Pronouncements Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes In June 2016, the FASB issued ASU 2016-13 - Financial Instruments-Credit Losses-Measurement of Credit Losses on Financial Instruments.

This guidance replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For SEC filers meeting certain criteria, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For SEC filers that meet the criteria of a smaller reporting company (including this Company) and for non-SEC registrant public companies and other organizations, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently in the process of its analysis of the impact of this guidance on its consolidated financial statements and does not expect the adoption of this guidance to have a material impact on the Company’s consolidated financial statements. Other than Accounting Standards Update (“ASU”) 2019-12 and ASU 2016-13 discussed above, all new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company.
