A resiliently compressible cushion of circular cross-section is disposed below the plunger and above a lower portion of the sucker rod string. A disk may be seated between the cushion and the plunger to distribute forces more evenly on the surface of the cushion. A resiliently compressible cylindrical sleeve, preferably having a plurality of annular grooves spaced thereabout, surrounds the shaft above the plunger. A coupling, adapted for connection to the lower portion of the sucker rod string, has a threaded end with a compressive face which abuts the outer end of the compressible cushion. A guide slidably mounted on the shaft has a threaded end with a compressive face thereon which abuts the outer end of the compressible sleeve.

Abstract: A system interactively controlled by a TV viewer remote superimposes portions of a scroll program guide over a basic programming signal for display on the viewer's display screen. A tuner has an input for receiving TV signals in a plurality of cable channels and an output for passing a signal of any selected one of said channels. A computer has an input for receiving any of a plurality of control signals from the TV viewer remote and an output for controlling the tuner to pass the signal of the selected one of the channels in response to one of the plurality of control signals from the TV viewer remote. The computer receives and stores a scroll input picture image signal containing local program guide data and generates a scroll output picture image signal consisting of at least a portion of the scroll input picture image signal. A combiner superimposes output picture image signal over the passed signal to provide a display signal for input to the viewer's display screen.

Abstract: This describes a portable non-pressurized anti-static device for eliminating static cling on clothes on which static electricity has built up. An absorbent material impregnated with an anti-static solution is supported by a frame. A cover, when in place, prevents the anti-static solution from being rubbed off or otherwise removed from the absorbent material until it is ready to be used. When static cling occurs, the wearer removes the cover and rubs the impregnated material against the area of the clothes affected, thereby removing the static electricity.

Abstract: In a dynamic noise reduction system, the release time versus frequency bandwidth is exponentially related and well beyond that achievable with a simple RC circuit.A dc control signal is derived from an input audio frequency signal by peak detecting the input signal, filtering the peak detected signal and controlling the release time of the filtered signal so that its release time is fast when the frequency is within a predetermined high range, its release time is moderate when the frequency is within a predetermined intermediate range and its release time is slow when the frequency is within a predetermined low range.

Abstract: An artificial bait is provided for use with a typical fishing hook or jig in which the hook or jig has an average density greater than the average density of water while the artificial bait has an average density less than the average density of water so that the hook tends to sink and the bait tends to float. The volume of the bait is proportioned to the volume of the hook so that their average density taken together slightly exceeds the average density of the water so that the hook and the bait together sink relatively slowly in the water. The bait is shaped to simulate a natural bait and is slidably engaged on the hook in a fashion similar to that in which a natural bait would be secured to the hook. As the hook and bait slowly sink, free portions of the bait extend upwardly toward the water surface and continue to respond to water currents and motion to maintain the tantalizing quality of the bait.

Abstract: A fishing rod case formed from an elongated, cylindrical tube with opposed open ends is divided into longitudinal segments, by a continuous hinge and a cut offset therefrom. The cut has a tongue and a groove extending fully along opposing edges thereof for mating when the tube is closed about the hinge. Straps mounted on an exterior surface of the tube hold the tube in this closed condition. When so mated, the tongue and groove cannot disengage even if pressure is placed on the tube surface. Resiliently compressible retainers are arranged in spaced apart opposing pairs within the tube. Each of the retainers is contoured to fit snugly in its respective tube segment. An upper portion of the retainer extends beyond the diametric dividing plane. Each retainer has several slits therein longitudinally aligned with the tube and with corresponding ones of the slits in corresponding ones of the pairs of segments.

Abstract: A hybrid eccentric wedge anchor includes a cylindrical anchor body, an eccentric wedge unit, and cylindrical leading end. The eccentric wedge unit includes a tapered body, a shoulder between the tapered body and the anchor body, and a crescent shaped clip rotatably positioned around the tapered body. The longitudinal axis of the tapered body is different from the longitudinal axis of the anchor body. The shoulder varies in width around the circumference of the anchor body. As the crescent shaped clip rotates around the tapered body, its outer circumference varies from being flush with the outer circumference of the cylindrical anchor body to extending beyond the outer circumference of the cylindrical anchor body.The hybrid eccentric wedge anchor can be configured in many useful anchor forms having the eccentric wedge unit. Examples include, but are not limited to, expansion bolt or drop-in configurations.
