  • Patent number: 4408928
    Abstract: A rectangular channel member has coplanar spaced-apart wall portions defining a slot therebetween and each having a flange extending from the slot inwardly of the channel member and away from the other wall portion at an acute angle. A generally U-shaped connector is disposable within the channel member across the slot and includes rectangular recesses receiving the flanges therein. A threaded fastener engageable with the connector extends through the slot for engagement with a support member, tighening of the fastener causing deformation of the flanges by the connector for wedging the flanges in the connector recesses. The support member may constitute a bracket for coupling the channel member to another channel member, several different bracket constructions being disclosed for coupling to different types of channel members and for different orientations of the channel members.

  • Patent number: 4404955
    Abstract: Disclosed is a forced-air heat extractor for use in a conventional fireplace. The heat extractor includes a plenum through which air is circulated by means of a blower which is positioned in an inlet duct connected to the plenum and located in the fireplace. The plenum is provided with a temperature responsive relief closure in its top wall which opens to permit the free flow of heated air upward toward the fireplace's flue in the event the temperature in the plenum exceeds a predetermined value, as might occur in the event of an interruption in the flow of forced air through the plenum, thus protecting the blower motor and associated circuitry from excessive temperatures. A bottom bar having an air inlet to which is coupled the inlet duct is positioned on the forward, lower portion of the fireplace. Upon this bottom bar a firescreen may be conveniently positioned. An outlet duct similarly couples heated air in the plenum to an air outlet in the bottom bar.

  • Patent number: 4404865
    Abstract: A trackball device includes a housing containing a plurality of rotatable supports and a ball seated thereon with a portion of the ball projecting through an opening in the housing for manual rotation by a user. First and second ones of the supports comprise shafts respectively rotatable about orthogonally related axes, the shafts being rotatably mounted in bearings receivable in slots in the housing accommodating slight movement thereof in directions perpendicular to the plane of the ball opening. Bias springs resiliently urge the bearings, and thereby the shafts and ball toward the ball opening. The device may also include illumination means and a light-transmitting ball.

  • Patent number: 4402222
    Abstract: A first signal at a first frequency which is a selected harmonic of the resonant frequency of a bolt in a first loaded condition is determined. Then there is determined a second signal at a second frequency being the same harmonic of the resonant frequency of the bolt in a second loaded condition. Both frequencies are multiplied by a factor M. The up input of a counter receives one of the signals for a predetermined duration, and the down input receives the other signal for the same duration. The number of pulses remaining in the counter is representative of the difference in load between the first and second loaded conditions.

  • Patent number: 4394422
    Abstract: Two ferrous-based components are bonded together to form a bonded structure and simultaneously a layer is diffused into the surfaces of the components. The process involves first placing the components in juxtaposition, and contacting the juxtaposed components with a molten lead bath having at least one diffusing element therein. One component may be a corrugated sheet and the other may be an uncorrugated or less corrugated sheet, the sheets being in the form of helixes interposed in each other to create a substantial number of fold lines being in contact with the surface of the uncorrugated sheet. Alternately, a sheet with projections may be used in place of the corrugated sheet.

  • Patent number: 4391309
    Abstract: A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath, the container being separated by a partition into a lower soap reservoir and an upper refill compartment, the latter adapted to enclose therein a removable refill cartridge and having a downwardly extending refill will with a plurality of keys upstanding from the bottom thereof. The cartridge has an outlet neck, the outer bottom surface of which has a like plurality of slots. The neck is closed by a pierceable membrane recessed therein and adapted to be received into the well so that a cartridge opening member pierces the membrane to accommodate free flow of liquid soap from the cartridge to the reservoir. The cartridge is entirely closed to define the liquid level in the reservoir at the bottom of the neck, and a drain hole in the reservoir wall above the bottom of the neck but below the tops of the keys prevents bootleg cartridges from being used in the soap dispenser.

  • Patent number: 4391308
    Abstract: A system for dispensing liquid soap comprising a closed wall structure defining a container with a partition separating the container into a lower liquid soap reservoir and an upper refill compartment. Dispensing means is carried by the container for dispensing liquid soap from the reservoir. A refill well having a refill aperture therethrough provides communication between the reservoir and the refill compartment and is dimensioned to permit the free flow of liquid soap therethrough. A pusher member is disposed in the refill well and extends upwardly toward the upper refill compartment to contact a refill cartridge containing liquid soap which has an outwardly extending neck defining an outlet with a tubular drain adaptor in the refill cartridge in sealing relation with the neck providing communication between the inside and outside of the cartridge.

  • Patent number: 4385398
    Abstract: A decoder circuit responds to a given code to provide an enabling signal for rendering an audio circuit operative. A push-button switch actuatable to monitor the channel is associated with timer and electronic switch.One connection places the receiver in either a monitor mode or a tone-squelch mode. A second connection places the receiver in condition to be unsquelched manually or by the carrier wave or by the proper code. The battery saver provides a continuous supply voltage during the first tone, the entirety of the code and for a time thereafter. The rate of the pulsed supply voltage produced after such time will be increased. Alternately, the receiver can be placed in the carrier-squelch mode. The receiver can be reset to the code-squelch mode and cause the pulsed supply voltage to revert to its usual rate. After the start of detection, pulses render ensuing circuitry nonresponsive to glitches.

  • Patent number: 4383630
    Abstract: An apparatus or machine for simultaneously removing and in situ severing of rails from a rail bed to produce a plurality of rail sections of predetermined lengths including a sled frame defining a rail channel with a block or blade mounted on the sled frame across the rail channel at the rear thereof. Ram means are mounted on the sled frame above the rail channel spaced from the block and moves along a ram path extending from a level above the rail channel to a level below the rail channel. Control mechanism is associated with the ram means for actuating the ram to travel along the ram path to contact a rail and force same against the block or blade to cause the rail to fracture, continued movement of the sled frame along the rail bed and continued operation of the ram means causing the rails to be lifted from the rail bed to be cut into predetermined lengths.

  • Patent number: 4382166
    Abstract: A joystick apparatus includes a tiltably mounted tube and a rod reciprocally movably axially therethrough. The tube has a frustoconical first actuator at one end thereof for operating engagement with a selected one or more of a plurality of first switches as the tube is tilted. The adjacent end of the rod carries a part-spherical second actuator for operating engagement with a second switch when the rod is extended from the tube, the shape of the second actuator keeping it in proper operating relationship with respect to the second switch regardless of the position of the tube.
