58052917, Sep 8, 1998

Filed:

Aug 14, 1996

Appl. No.:

8/689822

Inventors:

Timothy Wayne Calvin - Dunwoody GA
Edward Conrad Schneider - Marietta GA
Scott M. Caillier - Atlanta GA

Assignee:

Systronics, Inc. - Norcross GA

International Classification:

G01N 2184

US Classification:

356429

Abstract:

The invention is directed to an apparatus for measuring the thickness of flexible sheet material such as cloth, carpet, paper, sheet metal or plastic, for example. The apparatus includes a break member over which the sheet material is folded and advances. The apparatus also includes a light source and a light sensor that are preferably included in a laser scan micrometer. The apparatus also includes a carriage movable in a direction parallel to the break member. The light source is mounted to the carriage so that it opposes one side of the break member, and casts a shadow whose linear extent is indicative of the sheet material's thickness. The light sensor is mounted to the carriage on the opposite side of the break roller from that on which the light source is positioned. The light sensor and the light source can thus be used to generate sheet material thickness data at any predetermined position across the sheet material. The apparatus can include a traversing unit that drives the carriage to traverse the sheet material.

International Classification:

US Classification:

422 28

Abstract:

Each of a plurality of modules (A) have fitings (14) with automatically closed check valves (16) therein such that the interior of the module is sealed. The module is selectively interconnected with a sterilizer apparatus (B). Interconnecting tubing (60) selectively supplied liquid from a reservoir (30) to the module. A sterilant injection chamber (56) receives and punctures a sterilant ampule such that incoming water mixes with the sterilant concentrate forming a sterilant solution which is carried to the reservoir. A reservoir outlet valve (70) selectively permits the sterilant solution to pass from the reservoir through the interconnecting tubing into the module until the module and interconnecting tubing are completely filled. Thereafter, the reservoir outlet valve closes holding the sterilant in the interconnecting tubing as well as the module for sufficient duration to sterilize both. Concurrently, additional tap water is heated in the reservoir until it is sterile.

Abstract:

Each of a plurality of modules (A) have fittings (14) with automatically closed check valves (16) therein such that the interior of the module is hermetically sealed. The module is selectively interconnected with a sterilizer apparatus (B). Interconnecting tubing (60) selectively supplies liquid from a reservoir (30) to the module. A sterilant injection chamber (56) receives and punctures a sterilant ampule such that incoming water mixes with the sterilant concentrate forming a sterilant solution which is carried to the reservoir.
