  • Patent number: 4766367
    Abstract: An improved current mirror is described which has utility as either a stand alone current source or as a gain block whenever current gain or transimpedance gain is required. When used as a current source the current mirror exhibits higher output impedance, and when used as a gain block, the current mirror exhibits improved higher frequency performance and high transimpedance gain than prior art current mirrors.

  • Patent number: 4757755
    Abstract: A mobile cooking apparatus including a trailer vehicle having an elongated chassis with front and rear end walls, open sides, and a platform supporting one or more elongated cooking units and at least one cover member having foldable cover segments adapted to be moved downward over the chassis in a closed position to confine the cooking units within the chassis and moved upward to an open position in which the cooking units are exposed for cooking operations upon the chassis. The cover members are so constructed that a side cover segment clearly displays indicia, such as advertising material in either its open or closed position. Each cooking unit includes an elongated burner unit which is detachable mounted upon the chassis and which detachably supports a cooker member of any one of various types, such as a deep-fat fryer, boiler, broiler, solid griddle or an open grill.

  • Patent number: 4347744
    Abstract: A sealed differential pressure gauge of the general type shown in Phillips and Zoludow U.S. Pat. No. 3,645,140 in which a sealed housing is provided that includes a flexible diaphragm that is to be exposed to differential pressures to operate a sensitive and accurate motion transmitting indicator device that is in the form of a pivotally mounted helix cooperating with a range spring mounted magnet, with the range spring being linked to the diaphragm so that the movement of the diaphragm, indicates differential pressures and changes thereof, operates the indicator device for reading of the gauge. The housing comprises a housing member and back plate therefor that, together with the rim portion of the diaphragm, are shaped to provide for blowout capability of the gauge that is rearwardly directed out of the back of the gauge should overpressures be experienced when the gauge is in operation.

  • Patent number: 4154101
    Abstract: An air velocity gauge for direct measurement of low air flow or draft rates in the range of 20-400 feet per minute comprising a generally flat housing of quadrilateral shape defining a draft way therethrough and a set of opposed draft way inlet and outlet openings that are aligned with the plane of the housing that approximate the size and general shape of the way. A vane formed from a strip of Mylar polyester film is suspended pendulum fashion from the upper portion of the housing adjacent the draft way inlet and is creased longitudinally of same to rigidify the vane to act as such rather than as a flexible flap. The housing itself is in the form of an open centered center frame with open sides, to each side of which is applied a transparent side plate held in place by an adhesively backed opaque scale or scale plate that adheres to lands defined by the housing center frame for this purpose.

  • Patent number: 4125313
    Abstract: An electrical connection device provides an on-line extension of a multi-conductor electrical cable assembly permitting electrical entry of the cable circuits while they are operational, facilitates interconnection of plural multi-conductor electrical cable assemblies, enables hands-off probing of respective circuits of such assemblies, allows facile field modification of electrical equipment utilizing such assemblies, and the like.

  • Patent number: 4117452
    Abstract: Apparatus and method adapted for detecting the profile deflection condition in a wheel structure of the type comprised of a pneumatic tire mounted on a wheel rim and which deflection may be caused by tire under inflation or overloading. A sensing and actuating structure constructed from flexible material having high flex fatigue characteristics to include a body portion and a profile sensor is conveniently mounted to the drop center portion of the rim such that the profile sensor extends into the tire cavity so that it is positively engaged by the inside of the tire wall when tire profile deflection reaches an amount greater than a predetermined maximum amount due to overloading or under inflation, to thereby cause flexure in the profile sensor generally inwardly toward the rim. This flexure causes a piezoelectric device positioned adjacent the profile sensor to provide an electrical discharge.

  • Patent number: 4075603
    Abstract: Apparatus and method particularly adapted for detecting over and/or under inflated conditions in a wheel structure of the type comprised of a pneumatic tire mounted on a wheel rim. A generator unit is mounted to the wheel generally coaxial of the axis of wheel rotation and is constructed such that the generator rotor is operably journalled within the generator stator in a manner facilitating rotation of the rotor independently of the remainder of the generator unit and wheel itself. One side of the rotor is weighted so that as the wheel and generator unit are rotated, the rotor disposition remains generally stationary due to the influence of gravity forces on the weighted area. The relative rotation thus achieved between stator and rotor causes a voltage to be induced in the stator field winding which is utilized to energize a small radio transmitter mounted on the wheel with the generator unit.
