Appl. No.:

10/348807

Inventors:

Robert Goldstein - Los Angeles CA 90048
Leslie Goldstein - Los Angeles CA 90048

International Classification:

B43L 2302

US Classification:

30454, 30451, 144 281

Abstract:

A portable pencil sharpener, for use upon a belt, in sharpening pencils, having a housing having a top having a top opening, a rear, and defining an internal cavity. A belt clip is located on the rear to facilitate attachment to the belt. A motorized sharpener assembly is located within the housing for automatically sharpening a pencil when inserted through the top opening. A power pack is located within the housing and has batteries for powering the motorized sharpener assembly. A charging plug and charging circuit allow the batteries to be recharged for subsequent use.

International Classification:

G01N 3316

US Classification:

422 72

Abstract:

Medical testing apparatus including a microprocessor controlled centrifuge having a group of cuvettes therein. The apparatus also includes a microdiluter apparatus with a pair of pumps therein of differing diluting capability. The cuvettes have hollow main bodies produced from transparent material to allow analysis of the specimen within the cuvettes by a series of spectrophotometers adapted to read the cuvettes while they are rotating within the centrifuge. Bags of reagent are received within the cuvettes and are designed to burst upon reaching a given level of centrifugal force allowing the reagent to flow from the bags into a test chamber within the cuvette main body. Projections are provided on the cuvettes to control the orientation of the cuvettes when inserted into the microdiluter apparatus. A tab is provided on each cuvette in proper orientation to actuate the appropriate microdiluter pump for the test the cuvette is intended for. The cuvette projections also are coded with a binary code to produce a signal which indicates to the test apparatus which test is being carried out in the cuvette.

US Classification:

422 58

Abstract:

A cuvette for holding a liquid specimen during centrifugal testing and analysis of the specimen by a spectrophotometer. The cuvette includes a hollow main body produced from a transparent material to allow analysis of the specimen within the cuvette. Two bags of reagent are mounted within the cuvette main body and are designed to burst upon attainment of a given level of centrifugal force allowing the reagent to flow from the bags into a mixing chamber within the cuvette main body. A plug is sealingly mounted to the lid of the cuvette and is removable to allow insertion of the liquid specimen into the cuvette prior to centrifugal testing. Projections are provided on the cuvette to control the orientation of the cuvette when inserted into a diluter test receptacle. One projection on the cuvette contacts appropriate switch means within the test receptacle in turn operable to activate means for diluting the specimen prior to insertion into the cuvette. A container of desiccant is mounted within the cuvette and is operable to absorb vapors.
