  • Patent number: 4416628
    Abstract: An oral hygiene appliance is of the kind which includes a supply of liquid, a pump and a hand-held tip for directing the liquid where desired. A housing defines a cavity which has a surrounding wall closed by opposing end walls, the pump being seated within the cavity. A reservoir is closed at one end and has a shape in conformity with the housing to telescope thereover in covering relationship. Defined in one end of the reservoir is a valve seat which cooperates with a valve that closes during removal of the reservoir from the housing. On that end of the reservoir also is a coupling element which cooperates with a coupling member disposed in the surrounding wall of the housing. When that coupling relationship is established, the reservoir is seated on top of a side surface of the housing which, in turn, is lying on a table or the like. An outlet in the housing communicates with the hand-held tip and the pump is connected between that outlet and the coupling member.

  • Patent number: 4373887
    Abstract: Apparatus for producing a porous plastic molded product of uniform, predictable porosity throughout. A fluidized airstream of moldable plastic powder is formed. Water may be injected into said fluidized powder airstream for maintaining said powder in a uniform, fluidized dispersion. The moisturized, fluidized, powder airstream is injected into a cavity of a closed mold to fill said mold cavity with said powder. The mold is maintained at a temperature and for a time sufficient to at least partially fuse said powder particles together without melting said particles, thereby to form a porous, plastic molded product. The mold is partially separated for cooling the product which is then discharged from the mold. The product may be further cured by heating the molded product in an oven at a temperature and for a time sufficient to cure said molded product without melting said plastic or glazing said product.

  • Patent number: 4357906
    Abstract: A headgate has a pair of generally-upright elongated pipes spaced apart somewhat greater than the width of an animal to be restrained. The pipes are mounted for rotation, and spur gears are mounted respectively near one end of each of the pipes. A pair of elongated tubes are positioned generally inside of the pipes with the tubes being coupled to the pipes and at least an upper end portion of one of the tubes being movable with respect to its adjacent pipe but urged away therefrom. The assemblies of the other ends of the pipes and the adjacent ends of the tubes are releasably latchable into a closed condition in which the tubes are positioned between the pipes. As one basic feature, a pair of idler gears are disposed between the spur gears, with one of the idler gears being meshed with the first spur gear and the other idler gear being meshed with the second spur gear and with said idler gears also being mutually intermeshed, so that there is a complete slaving action of the pipes in rotation.

  • Patent number: 4357594
    Abstract: A vehicular hazard warning system has an indicator on the vehicle that is energizable to yield a warning signal. The onset of a hazardous condition is detected and, as a result, a control signal is developed which has a variable parameter the amount of which is proportional to the degree of hazard represented by the condition. In response to that condition, the indicator is energized in a manner which quantitatively has a magnitude that is proportional to the amount of hazard. The system primarily responds to abrupt deceleration. It also preferably is responsive to such other inputs as brake pressure, wheel speed change, inertial forces and operator-controlled pedal movement.

  • Patent number: 4354475
    Abstract: An internal combustion engine has a carburetor, with a throttle valve and a choke valve, that delivers a fuel-air mixture to the intake manifold. An auxiliary system uses a blending chamber which feeds the manifold exclusive of the engine carburetor and through a metering valve that responds to engine vacuum level for controlling the amount of blend drawn through the blending chamber. At the inlet of the blending chamber is an atomizing throat fed with fuel and air. The drawing of the blend from the outlet of the chamber draws air through the throat and into comminglement with liquid fuel which is atomized by action of the throat. Under normal operating conditions and adjustment, the auxiliary system improves engine performance by increasing fuel economy and reducing engine exhaust pollution.

  • Patent number: 4347732
    Abstract: A pair of electrodes are spaced apart on an electrically-insulating support surface. Disposed on the surface in a position bridging the electrodes is a sensor that exhibits a change in conductivity in response to exposure of the material to a wide variety of certain flammable and toxic gases. Overlying the sensor is a molecular sieve passivation layer composed of a porous solid material that has a pore size no larger than the molecular size of the gas to be sensed. The molecular sieve passivation layer can be incorporated onto various solid state and catalytic-type gas sensors, including metal oxide based solid-state sensors such as, for example, those of a zinc oxide base. With or without the sieve, the most salient form of zinc oxide based sensor is zinc oxide doped with gallium oxide. It is expedient to use such improved sensors as a discrete device or in a hybrid array for environmental ambient qualification as incorporated into a portable instrument.
