Abstract: An electromechanically operated dockboard. The dockboard includes a ramp hinged at its rear edge to a supporting frame and the ramp is adapted to be moved from a generally horizontal cross traffic position to an upwardly inclined position by operation of a recirculating ball screw unit, which is connected between the frame and the ramp and is driven by a permanent magnet motor. A lip is hinged to the front edge of the ramp and can be pivoted from a pendant, downwardly hanging position to an extended position where it forms an extension to the ramp. Deactivation of the ball screw unit, after the ramp is elevated, causes the ramp to fall by gravity, and as the ramp descends, the lip is lifted to the extended position where it will engage the bed of the truck. During the descent of the ramp the ball screw unit is driven in a reverse direction and the permanent magnet motor serves as a brake to control the speed of descent.

Abstract: Method of making an insulated gate field effect transistor is described in which the surface of a silicon semiconductor is covered in whole or in part with a layer of a masking material which masks against oxidation, such as silicon nitride. Areas of the silicon surface are exposed for the source and drain regions, leaving the oxidation mask over the future channel. When the source and drain regions have been made, as for example by diffusion, the device is subjected to oxidation, causing the growth of a thick oxide which sinks into the silicon surface where it is not masked by the oxidation mask. Among the advantages obtained are fewer precise masking steps, a flatter device surface, and reduced gate overlap of the source and drain.

Abstract: A high lift energy reclaiming circuit for use in a vapor compression refrigeration system, the circuit being interposed in the system between the compressor discharge line and the condenser inlet line. Refrigerant vapors discharged from the compressor are exposed to, and condensed into, a strong absorbent solution to develop temperatures within the mixture that are in excess of the saturation temperature of the discharge vapors. The mixture is brought into a heat exchanger where the high temperature energy is recovered by a heat reclaiming substance, such as water or the like. The diluted absorbent in the mixture is then separated from unabsorbed refrigerant vapors and the dilute solution flash cooled by expanding the solution to the inlet pressure of the compressor.

Abstract: An operative internal combustion engine is transparent for demonstration of internal combustion engine principles.

Other portions of the engine are transparent to enable their contained parts to be observed during operation. The engine also has an enlarged flywheel to permit operation of the engine at low, observable speeds. The invention burns low carbon fuels such as alcohol to keep the cylinder walls clean and operate without polluting the air.

Abstract: A male urinal automatically flushes when the user steps off a foot plate. The foot plate pneumatically sealed is resiliently deformable and is connected by a pneumatic conduit to a normally open switch whose closure completes a circuit that opens an electrically controlled valve to flush the urinal so long as the switch is closed. Release of pressure on the foot plate creates subatmospheric pressure as the foot plate returns to its undeformed condition, which collapses a diaphragm that permits the normally open switch to close. An air bleed restores the pressure in the foot plate to atmospheric at a controlled rate that predetermines the duration of flushing.

Abstract: A method of rigidly fixing an end portion of an elongated column member within a cavity in a body member. A quantity of hardenable adhesive material is placed into the cavity such that when the column member end portion is inserted into the cavity, the resulting displacement of a portion of the adhesive material causes the adhesive material substantially exactly to fill the cavity. The column member end portion is then inserted into the cavity, and the adhesive material is allowed to harden. The angular position of the column member relative to the body member can be adjusted as desired prior to hardening of the adhesive material. Preferably, the method is automated, including injecting a measured amount of adhesive material into the cavity and holding the column member and the body member in a jig while the adhesive material hardens. The adhesive material can be an epoxy resin, and if desired, the hardening can be accomplished by heat curing.

Abstract: A self-wringing mop includes a handle having at one end thereof a housing in the configuration of an open bottom clevis. A pair of roller sets are journalled adjacent the bottom of the clevis with the clevis end walls providing a pair of opposed inverted U-shaped guides. A replaceble mop head includes a sponge and an elongate spine having opposed concave side panels. The spine is engaged by a bail formed at the end of a rod which extends through the handle into the housing. Normally, the rollers are urged against the concave side panels of the spine and the sponge projects beneath the housing.

Axial head movement is guided, and lateral movement is prevented by keyways formed in the spine and engaged by opposed edges of the housing end wall guides. The mop head is ejected from its normal position by forcing the rod downward which disengages the keyways from the guide.
