Abstract: A desk top shaker for unclogging a pen having ink which clogs the pen point, including a housing having an opening, a casing supported on a shaft in the housing and receiving the pen through the opening to removably hold the pen, a motor in the housing for vibrating the shaft and hence, the pen, and a switch on the housing to turn on the motor. The casing is removable from the housing and is closed on the bottom to catch ink which is ejected when the motor is turned on to unclog the pen. An adaptor is connectable to the top of the casing to receive and hold pens of different sizes.

Abstract: There is disclosed an apparatus for washing vegetables, fruits and the like foodstuffs. It is formed of a vessel and a basket, within the vessel, for containing the foodstuffs. The basket is mounted in the vessel for rotation about the vertical axis of the latter and a flexible band is fixed, at one end, to the rotation bearing of the basket and extends outside the vessel to cause rotation, when pulled, of the foodstuffs containing basket. The vessel has a cover which is formed with a chamber apertured at the bottom and the basket has a disc at the top with a series of holes registering, during rotation, with the apertured bottom of the chamber so that water poured in the chamber may flow into the basket through such holes during rotation of the said basket.

Abstract: A substrate stripping and cleaning apparatus including a closed bowl with an exhaust vent and a liquid drain, a rotating turntable in the bowl carrying baskets of substrates, a spray post with multiple fluid passages, orifices and spray nozzles directing rinsing spray outwardly against the turntable and substrates, rinsing water manifold pipes on the turntable and revolving therewith and having nozzles directing rinsing water to all portions of the inner surfaces of the bowl, the pipes being supplied with water through passages in the drive shaft for the turntable.

Abstract: In a method and apparatus for applying light sensitive materials to semiconductor slices, a plurality of semiconductor slices are supported in a spaced apart array extending along an axis. The slices are supported on knife edges positioned at circumferentially spaced points about the axis and each extending angularly both with respect to the axis and with respect to the radii of the slices so that the slices are supported by means of point contact with their edge portions. In one embodiment the knife edge comprise combs mounted in a cylindrical support fixture formed from an open material and including hingedly interconnected half cylinders. In another embodiment the knife edges are supported in a cup-shaped support fixture formed from an open material and adapted to receive semiconductor slices of varying sizes and particularly broken semiconductor slices.Light sensitive material is simultaneously applied to all of the semiconductor slices in the support fixture.
