Abstract: A furnace control system to control burner operation of a multifuel furnace to reduce primary fuel consumption of either oil or gas of the multifuel furnace. The system controls a primary fuel to initially kindle a secondary fuel when the fire reaches a self-sustaining burning rate, the primary fuel is shut off but the burner fan continues to run to force a draft and insure complete combustion of the secondary fuel and the volatile gases. The furnace control system is utilized as original equipment manufacturer incorporated into the controls for a burner of a multifuel furnace or as a retrofit furnace control system to control the burner operation of the multifuel furnace.

Abstract: A headset having an ear cup with a beveled spherical socket hole which rotatably supports and seats a spherical boom support swivel. The swivel consists of two half ball elements held in registration on an asymmetrical boom through gripping action of an asymmetrical hole in each of the half ball elements. Opposing ramp projections and sockets in the half ball elements bias the half ball elements in opposing rotational motion about the boom axis when the half balls are urged toward each other by a floating spring retainer plate thus producing a torque on the boom which is tightly gripped by the opposing half ball elements. Opposing outward projections on the boom mate with depressions in the half ball elements to prevent longitudinal sliding of the boom opposite the swivel and adjacent the operator's mouth. The swivel is rotatably held in the beveled spherical socket hole by the floating spring retainer plate having a flanged dish forming a ball seat swivel.

Abstract: A solderless coaxial cable connector for securely holding coaxial cable without indentation to the cable dielectric and offering a high strength joint at the connector. A conductive cylindrical body having four annular ratchet teeth keeps the connector from rotating when mated. The small end of the body accomodates a screw sleeve or a crimp sleeve for the outer conductors of the coaxial cable connector. The large end of the body accommodates a tubular insulator with a bore for a crimp type contact for a solid or stranded center conductor of the coaxial cable. A female nut is held in place at the center portion of the body between the large diameter section and the sleeve, either crimp or screw, to act as a coupling nut when the connector is mated.

Abstract: A golf club having a shaft, a handle which affixes to one end of the shaft, and a club head which affixes to the other end of the shaft at an inverted right angle tee to the shaft. The club head is of the shape of a small trapezoid top portion symetrically positioned on top of a large trapezoid bottom portion. The shaft attaches to the top center of the small trapezoid top portion so that the weight of the club head is equally distributed over entire length of and circumferentially around the shaft. A plumb bob is contained within a cylinder assembly of the handle and is affixed to a removable top portion of the handle. A ball weighted string or string attached to a spring retracts the string into the cylinder when the removable top is replaced onto the handle.

The source and detector are adjustably disposed on the component of an automobile to be positioned in a predetermined attitude with respect to a reference device that is, in turn, positioned in a predetermined attitude with respect to the vehicle, such device comprising a radiant energy reflecting planar surface.

Abstract: A rapid channel skip system for radio receiver having a single channel skipping switch to inhibit the radio receiver from receiving any of selected channels of a plurality of channels of predetermined frequencies while scanning repetitively those channel selected to be received. A clock oscillator having a scan frequency controls the scanning time of channels to be received and a skip oscillator having a skip frequency oscillates for one cycle to skip over a channel. The channel skipping switch is utilized to skip, inhibit, bypass, look around, etc., any channel of a plurality of channels a listener does not wish to receive when the rapid channel skip system connected between the squelch control and the oscillator of the radio receiver has stopped on a channel while scanning in the scan mode or has been stepped to a particular channel by the channel stepping switch in the manual mode by actuating the switch.

Abstract: A microphone of the hand held type used in portable or remote radio communications systems in which improved resistance to shock, wet environmental conditions is achieved by using a resilient mounting means for a receiver disposed inside a hollow housing which includes a stop for limiting motion of the receiver in the resilient mounting means and through the use of a loosely mounted water impervious membrane over the active side of the receiver and further disposing an open cell, foamed plastic element over the outside of the plastic membrane.

Abstract: A channel skip memory system for radio receiver having a single channel skipping switch to inhibit the radio receiver from receiving any of selected channels of a plurality of channels of predetermined frequencies while scanning repetitively those channels selected to be received. The channel skipping switch is utilized to skip, inhibit, bypass, look around, etc., any channel of a plurality of channels a listener does not wish to receive when the channel skip memory system connected between the squelch control and the oscillator of the radio receiver has stopped on a channel while scanning in the scan mode or has been stepped to a particular channel by the channel stepping switch in the manual mode by actuating the switch. If the channel skipping switch is actuated a second time when utilizing resettable memory elements on an inhibited channel in the manual mode, the channel is enabled. The channel stepping switch is not functional during the scanning mode.

Abstract: A digital frequency synthesizer in which a BCD.div. N counter is used to provide the desired frequencies of operation without requiring further BCD decoding operations to provide direct channel number interface. This is accomplished by selecting a value of (N) corresponding to a desired channel number (CN) and selecting a downmix heterodyning frequency so that the lower order bits of (N) are equal to the desired (CN) without need for further conversation.

Abstract: A rotary drill bit having a rolling cutter mounted on a journal by means of internal, anti-friction bearings is provided with a sealing ring between the journal and cutter. The journal and cutter have facing, circumferential surfaces of which one surface is provided with a groove facing the other surface. One or more annular sealing rings are spring pressed against and carried by the other surface and extend into and seal against the annular groove to seal the interior bearings from contamination. The one or more rings are forced under spring pressure into the annular groove when the cutter is mounted to the journal, the ring or rings returning under spring pressure to press against and be carried by the other circumferential surface while yet extending into and sealing against the groove.

Abstract: A rotary drill bit is provided with confronting large hard annular bearing surfaces on the journal-bearing body and on the journal-mounted conical cutter of the bit. The hard surfaces are generally normal to the axis of rotation of the cutter to bear axial loads, and provide a large bearing area resulting in relatively low unit pressures on the bearing surface. The hardness of the bearing surfaces should be greater than the hardness of the rock or other material being drilled. The journal and cutter may have confronting but spaced inner hard bearing surfaces which come into sliding, bearing contact with each other as the first-mentioned bearing surfaces are worn down. Cooling means are provided to cool the bearing surfaces, and an internal ball bearing and race assembly permits limited movement of the cutter axially on the journal to allow for wear of the bearing surfaces and to eventually bear axial loads. Also described is a nozzle means for sweeping cuttings to the periphery of the drill hole.
