Abstract: A vehicle suspension system incorporating an air spring for installation on a vehicle that already has a leaf spring suspension system. The air spring suspension system is supported at an end of the leaf spring assembly and it has a spring seat connected to a shackle that is connected to an end of the leaf spring assembly. A transverse bolster rail allows the air spring assembly to have a wide base mount laterally outboard of the vehicle chassis and the leaf spring suspension. A cross radius rod prevents transverse movements of the axle. A sway bar connected between the left and right side air spring suspension assemblies rigidizes and stabilizes the suspension system.

Abstract: An antenna for receiving satellite broadcast television reception only (TVRO) programming, includes a main reflector dish, a pivot tube for pivotally mounting the reflector dish from a support, and an integrally formed azimuth track and drive comprising an arcuate track bolted to the back of the reflector dish with a trolley drive which engages the pivotal mount to drive the reflector dish along the azimuth to move the dish from satellite to satellite. The integral track and drive rides freely in the vertical direction on the pivotal mount to permit adjustment of the declination and elevation of the main reflector dish without disassembly or removal of the azimuth track and drive.

Abstract: A window guard latch with emergency release comprising a bracket having a channel for receiving a portion of the window guard, a lock for engaging the portion of the window guard received in the channel, the lock having a trigger for releasing the engagement with the window guard, and a solenoid linked to the trigger to operate it. A control box, mounted inside the building has an RF signal detector and means to activate the solenoid in response to the detector to release the window guard. Smoke detectors which trigger an RF transmitter and portable push button RF transmitters can transmit an RF signal to remotely activate the release mechanism.

Abstract: A reduced height monopole/crossed slot antenna having generally parallel spaced ground planes, the upper one of which has a capacitively loaded slot therein formed by crossed slot portions. A stripline is located between the ground planes offset toward the upper ground plane, and is formed by crossed stripline portions. A monopole extends from the intersection of the crossed stripline portions through the intersection of the crossed slot portions orthogonally to the upper ground plane, and is top hat loaded at the outer end thereof. The stripline is fed at selective ends thereof.

Abstract: An improved syringe of the type comprising a barrel having a needle extending from the lower end, the syringe further comprising a knob extending outwardly from the barrel near the lower end, and a sheath slideably mounted on the barrel and slideable between a retracted position and an extended position. The sheath has a slot for receiving the knob, the slot having tabs for releasably retaining the sheath in its retracted position releasable upon downward pressure applied to the sheath, and tabs for lockingly engaging the knob to lock the sheath in the extended position.

Abstract: A dual-walled coiled plate heat exchanger with vented interface includes four plates of stainless steeel welded together and inflated to form a refrigerant passage between two of the plates, a water passage between another two of the plates, and a vented interface between the two passages such that leakage from either of the passages into the interface is vented to the atmosphere and not to the other passage.

Abstract: A fat injection system for a pellet mill includes a plurality of nozzles mounted within the pelleting chamber and adjacent the die and rollers with a steam and fat line connected to each nozzle for mixing fat with steam and spraying the mixture onto the pellets immediately as they are formed.

Abstract: A disposable injection transmitter for use between injecting needles and a primary injection site. A body having a passage through it. A hollow auxiliary needle joined to the body in communication with one end of the passage and adapted to penetrate through and reside in the primary injection site. An elastomeric wall joined to the body and covering the other end of the passage and adapted to receive a series of injecting needles through it to inject fluids into or beyond the passage.

Abstract: A battery charger circuit having a main transformer and a boost transformer. The main transformer supplies power to produce a DC main charging current at the circuit output for charging a battery. The boost transformer supplies power to produce a DC trickle charging current at the circuit output. The power rating of the boost transformer is a small percentage of that of the main transformer.

Abstract: A system for adding heat to dry material as it is conditioned in preparation for pelleting in a pellet mill includes a plurality of groups of microwave magnetrons and a control system to control the energization of those magnetrons in response to the throughput of the dry material and the temperature or temperature change of the material.

Abstract: An improved polarity switch for connection between a dual antenna system and a satellite television reception system has a first embodiment which utilizes a pin diode switch between the dual antenna system and each of a plurality of receivers to permit use of the receiver to select one of the two antenna feeds for decoding and display at that television set. A second embodiment is also disclosed which utilizes an electromechanical relay to isolate the antenna feeds from each receiver.

Abstract: A personal ion inhaler comprising a tube with an air passage therethrough having an inlet and outlet end. A filter means is secured in the air passage near the inlet end. A mouthpiece is secured at the outlet end. There is an ionization chamber in the air passage having a conductive lining and an electrode. A shuttle switch only connects a charge storage capacitor to the electrode when air is drawn through the inhaler to ionize the air passing the electrode.

Abstract: A belt with a buckle having a rigidly attached socket member to receive the shank of a fishing rod holder. A fishing rod may be inserted or removed to provide a place for the fishing rod to be held and that frees the hands of the fisherman.

Abstract: A product turning device suitable for direct mounting in a conveyor stream includes a first driven input roller which applies an accelerating force to the product as it enters the turner and which has a knurl at one end to slightly skew the product into the turning motion, and a transfer roller with a multi-beveled knurl which moves transversely against the side of the product and contacts its bottom surface to accomplish the turn. A series of guide bumpers and a guide bracket maintain alignment of the product as the input roller skews the product, and the transfer roller turns it.

Abstract: A back clip comprising a clip body and a drive pin. A wall anchor is integral with the clip body and has fingers laterally expandable when the drive pin is driven through the anchor. The fingers have transverse wall portions engageable by the drive pin to swing the fingers to substantially ninety degree angles to the axis of the drive pin and anchor. A web is in front of the transverse wall portions in the path of the drive pin. A hook member on the body receives a shelf wire. A stop is hinged to the body by an integral short plastic strap and is pivotable to block the open side of the hook member and to hide the head of the drive pin.

Abstract: A wall anchor having a socket and a drive pin. A passage within the socket receives the drive pin. Fingers on the leading end of the socket have walls in the path of the pin. The fingers pivot into contact with the back surface of the wall by a cam action of the drive pin against the fingers and slightly spaced from a web in front of the fingers. Ribs on the inner wall of the passage grip the drive pin in a ready position. A head on the socket and barbs on the outer wall hold the socket in another part. The fingers have generally flat faces that are barbed to make maximum contact with the wall surface. The drive pin has a shank at its lead portion and helical threads at its trailing portion with a head on the trailing end. The drive pin can be driven by a hammer through the socket and can be withdrawn by the use of a screwdriver.
