Abstract: A window latch and handle assembly exhibiting an attractive appearance while providing a high degree of strength and small size. The assembly employs a pair of body members which are secured to a door or window frame and a unitary handle and latch. The handle extends from one side of the assembly of the two body parts and the latch from the opposite side thereof. A lock member with an elongated arm surface engages a key slot in the handle and latch. When in one orientation, the locking member allows the handle and latch to move laterally against the resistance of return spring and when turned 90.degree., effectively prevents movement of the handle and latch by direct broad area contact with one of the body parts. When rotated 90.degree., the lock member rests in the key slot allowing limited movement of the handle and latch to release the door or window.

Abstract: An automotive service ramp comprising a unitary body member including a ramp portion with integral side stiffening, tire retaining rails, a contoured rest portion to receive the tire of an automobile, and an extension beyond the rest portion which constitutes a leg portion.The ramp portion has transverse corrugations, is contoured transversely to match normal tire cross sections and has depending stiffening sides. A slight edge rail extends above the surface of the ramp.A handle is pivotally secured to the body in a position whereby it may be grasped to carry the ramp with the ramp portion hanging downward. The handle is pivoted to overlie the rest and leg portion when not in use and to be out of the way. An integral retainer portion of the body member holds the handle at a fixed position when not in use.

Abstract: Improved partial turn fastener designed to hold a pair of superimposed panels in fixed registration with each other and allowing release of one panel from the other by merely a partial turn of the knob or screw of the fastener. Featured is the arrangement whereby the panels are maintained together by the pressure applied between a threaded screw and a nut without any intervening springs and the fastening force being determined by the strength of the screw and mating nut. A spring assistance is used for release of the fastener from a partial turn of movement. Locking pin means cooperating with the screw and nut prevent unwanted disassembly of the screw from the nut during unlocking operation.

Abstract: A system for phase control of multiple high power microwave frequency amplifiers. A pilot frequency lower than the frequency to be amplified is used to modulate the microwave signal. The pilot frequency is detected at the output of the amplifier stage and phase compared with the original pilot frequency. Any difference is used to produce a phase correction signal applied to the amplifier. Phase modulatable traveling wave tubes are the power amplifiers. One alternate embodiment involves a steerable array employing an additional pilot frequency correction introduced into the pilot signal. In another embodiment a cross field amplifier is placed in series with a traveling wave tube amplifier in the phase correction loop.

Abstract: A device for assisting in the training of volleyball players to learn the art and defense to the play known as spiking. This device is a holder for a volleyball at selected elevations near the volleyball net or a rebound surface. The holder allows a player to run, jump and strike the ball in a manner to drive it with great energy over the net and into opposing team's territory. The rebounder deflects a spiked ball in an unpredictable direction. The rebounder comprises a plurality of arms spaced less than a volleyball diameter apart and constituting an operating head. The operating head is positioned adjustably by a standard, whereby it may be located above and adjacent to a volleyball net to deflect unpredictably volleyballs spiked against it, for training of the defense to volleyball spiking.

Abstract: A telescoping jack stand made of stamped metal parts with a pair of angularly extending legs which are pivotally mounted with respect to each other. The legs define an aperture between the legs with inwardly extending integral teeth. A central column member includes matching teeth and corresponding in shape and dimension with the aperture between the two legs. The central column includes recesses corresponding to the integral teeth of the legs. The legs are pivoted with respect to each other so that upon engagement of the teeth with the recesses in the column, additional load tends to pivot the teeth into greater engagement with the column and provide improved stability.
