SCHEDULE 13D

This Amendment No. 2 to Schedule 13D (this “Amendment No. 2”) amends and supplements the Schedule 13D filed with the United States Securities and Exchange Commission (the “SEC”) on November 21, 2003 (as amended by Amendment No. 1 thereto previously filed with the SEC on February 15, 2008, the “Original Schedule 13D”), on behalf of Irwin Gruverman and Marjorie Gruverman.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 of the Original Schedule 13D is hereby amended and restated in its entirety as set forth below:

Between November 18, 2003 and December 24, 2007, Mr. Gruverman made several purchases of the Issuer’s Common Stock and exercised stock options for the purchase of shares of the Issuer’s Common Stock. All purchases and exercises of stock options were with Mr. Gruverman’s personal funds, except certain of the stock option exercises were cashless net exercises of outstanding stock options and accordingly, no funds were required in connection with such cashless exercises of stock options.  Mr. Gruverman has also made bona fide gifts of shares of the Issuer’s Common Stock and sold shares of the Issuer’s Common Stock.  This Amendment No. 2 shows Irwin Gruverman’s and Marjorie Gruverman’s ownership of Issuer’s Common Stock following Mr. Gruverman’s last transaction in the Issuer’s Common Stock.

Item 4.

Purpose of Transaction

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following at the end thereof:

Tender and Support Agreement

On January 10, 2011, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) with IDEX Corporation, a Delaware corporation (“IDEX”), and Nano Merger Sub, Inc., a Delaware corporation and a wholly-owned direct subsidiary of IDEX (the “Purchaser”), pursuant to which IDEX will acquire the Issuer in a two-step transaction.

On the terms and subject to the conditions set forth in the Merger Agreement, IDEX, through the Purchaser, will commence a cash tender offer (the “Offer”) for all of the Issuer’s outstanding shares of Common Stock (the “Shares”), for $1.35 per Share, net to the seller in cash, without interest thereon, and subject to adjustment as provided in the Merger Agreement (the “Offer Price”).

Following the completion of the Offer and upon the satisfaction of certain conditions described in the Merger Agreement, including, if required, a vote of the Issuer’s shareholders with respect to the adoption of the Merger Agreement, the Purchaser will be merged with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly owned subsidiary of IDEX. At the effective time of the Merger, holders of Shares not purchased in the Offer (other than those Shares held by the Issuer’s shareholders who have properly exercised their dissenters’ rights under Section 262 of the Delaware General Corporation Law) will be cancelled and converted into the right to receive the Offer Price in cash, without interest, on the terms and subject to the conditions set forth in the Merger

Agreement.

On January 10, 2011 and January 12, 2011, respectively, Irwin Gruverman and Marjorie Gruverman entered into Tender and Support Agreements (the “Tender and Support Agreements”) with IDEX and the Purchaser whereby they agreed, among other things, to tender all of their Shares in the Offer.  In addition, Irwin Gruverman and Marjorie Gruverman agreed not to directly or indirectly transfer their Shares during the term of the Tender and Support Agreement, subject to certain exceptions.  Except in limited circumstances, the Tender and Support Agreements terminate upon termination of the Merger Agreement or the occurrence of certain other events.

The foregoing description of the Tender and Support Agreements is qualified in its entirety by reference to the Tender and Support Agreements, copies of which are attached hereto as Exhibit 1 and Exhibit 2 and incorporated herein by reference.

Mr. Gruverman does not share voting or dispositive power with respect to 100,000 shares of the Issuer’s Common Stock, which represents an additional 0.96% of the Issuer’s outstanding shares of Common Stock, held by his spouse, Marjorie Gruverman, to which he also disclaims any beneficial ownership.
