Abstract: ABSTRACT OF THE DISCLOSURE      A fluid actuated brake assembly for use with a parallelogram linkage on a dental tray support arm is described.  Floating brake shoes positioned on opposite sides of one member of the parallelogram linkage with one of the brake shoes pivotably and slideably attached to the other member of the parallelogram linkage provides a braking and locking effect between the two members of the parallelogram linkage to provide an efficient brake for a dental tray support arm.  Upon fluid actuation of the brake assembly, the brake shoes grip one member of the parallelogram and form a rigid connection with the other member of the parallelogram to prevent relative movement of the parallelogram linkage members.  The frictional brake assembly also provides an override feature above a predetermined force level to prevent accidental jamming of the dental tray support arm against an object. Additionally, fluid actuation of the brake assembly provides for substantially instantaneous locking and unlocking of the dental tray support arm.  The fluid actuation mechanism is conveniently operated by an air brake switch which is located near the dental tray.

Abstract: ABSTRACT     In a system for moving large quantities of pulverulent material from receiving hoppers, such as those of a fly ash precipitator, into a pressurized air conveyor pipeline, separate auger conveyors move material from a first line of receiving hoppers and from a second line of receiving hoppers downstream into gravity material inlets at opposite ends of an effectively airtight pressure con-veyor casing.  In the casing auger conveyor flights of opposite hand and substantially smaller than the casing move it toward a central outlet through which it drops into the pressurized air conveyor pipeline.  Above the outlet the auger conveyor shaft has radial material agitating rods.          The system is cycled to alternately feed material into the pressure conveyor casing at receiving hopper pressure, which is about atmospheric pressure, and out of the pressure con-veyor casing at pipeline pressure.  The pressure conveyor is pressurized through a series of air pressure pipes spaced along the casing substantially tangent to the lower-most part thereof, and casing pressure is relieved through a pipe above the central outlet.

Abstract: PULSE SHAPING AND AMPLIFYING CIRCUIT      ABSTRACT OF THE DISCLOSURE         A pulse shaping and amplifying circuit receives direct current electrical power from a source and serves to supply a pulse of electrical energy to a load.  First and second switches  (e.g., transistor switches) are interconnected such that only one is conductive at any one time.  The first switch, when conductive serves to connect a capacitor which forms part of an oscillatory circuit,  further including an inductor in the form of a transformer primary winding, to the source to place an electrical charge on that capacitor in a first direction.         When the second switch is rendered conductive  (and the first opened) the load is connected in circuit with the oscillatory circuit and the capacitor discharges to deliver a pulse of electrical power to the load with any excess power being utilized to charge the capacitor in the second direction.  A flyback current path including a transformer secondary winding, closely coupled to the primary winding, and a diode is connected in parallel with the capacitor such that the capacitor again changes direction of charge to thus be charges in the direction for supplying the next pulse to the load.  If desired, a second capacitor may be connected in parallel with the oscillatory circuit to improve the rise time of the pulse supplied to the load.

Abstract: ABSTRACT     NON-SPILL LIQUID FUEL TANKS      A liquid fuel tank for a vehicle is provided with a fuel outlet duct in a circuit about the base of the tank and fuel outlet duct vents connected to the outlet duct and extending above the highest part of the tank.  During normal operation of the tank, a non-return air vent allows the flow of fuel from the outlet duct.  In the event of an accident, or some other occurrence which results in the tank being tilted, further fuel flow from the outlet duct is cut off by air drawn into the fuel outlet duct from the outlet duct vents.  The angle through which the tank must be tilted to allow air from the outlet duct vents to be drawn into the outlet duct may be predetermined by the extent of the circuit about the base of the tank of the outlet duct.          Such a non-spill fuel tank, which is self contained in operation, is suitable for use in on-road and off-road wheeled and tracked vehicles, hovercraft, and aircraft which are in danger of being blown over when on the ground.

Abstract: CURRENT SENSING RELAY                        ABSTRACT     A current sensing relay assembly is disclosed wherein current sensing devices are integrated with relay outputs on a single printed circuit assembly.  By integrating the output and sensor, all additional external equipment and wiring are eliminated.  The current sensors achieve a maximum current to minimum current sensing ratio exceeding 100 by sensing current flow magnetically using Hall-effect devices and appropriate amplifier circuitry.  Multiple channels of current sensing are achieved without requiring individual sensitivity adjustments by utilizing common threshold references for all channels.  The electronic portion of the sensor achieves immunity from power line noise and a stable sensing threshold by a combination of circuit design and layout.  In the illustrated embodiment, the magnetic portion of the sensor is contained entirely in a single module that incorporates the sensing coil, magnetic circuit, Hall-effect sensor, and magnetic shield.
