Abstract: An apparatus and method for created star-shaped figures is disclosed. The apparatus for drawing a star having a plurality of points is includes a guide piece having a plurality of spokes corresponding in number to the plurality of points of the star and radiating from a central point and a triangular stencil having a plurality of guidelines extending from a first side of the stencil to a second side of the stencil and a vertical centerline placed over the guide piece.

Abstract: A physiologically appropriate hand-held cutter for fabric and sheet goods comprising a rotary cutter blade encased within a handle that includes a recessed depression within the handle surface essentially proximate the area of the handle enclosing the blade within which the user's thumb is positioned when the cutter is in use and optionally including a head section forward the section enclosing the blade for receiving the user's forefinger. The cutter fits naturally in the palm of the hand and reduces strain on the carpel tunnel area of the wrist.

Abstract: A refrigerant recovery and purification system that includes a refrigerant compressor having an inlet for connection to refrigeration equipment under service from which refrigerant is to be recovered. The outlet of the compressor is connected through a condenser to a refrigerant storage vessel or container, with the condenser at least partially liquifying refrigerant prior to passage to the storage container. A liquid refrigerant pump is connected for selectively circulating refrigerant in liquid phase in a closed path from the storage container through a filter for removing contaminants from the refrigerant, and then through the condenser back to the storage container. Refrigerant circulated by the liquid pump in the closed path is thus simultaneously purified by passage through the filter and cooled by passage through the condenser.
