Abstract: An assembly for transferring solid particulate matter has a pressurized vessel for retaining a pre-determined quantity of the solid material. A discharge conduit connected to the vessel carries the solid material to a loading vessel, be it a processing tank, a storage vessel, or any other similar container. A discharge nozzle carried by a distant end of the discharge conduit is also connected to a dust collection container. Vacuum created in the dust collection container facilitates entrapment of dust particles generated during transfer of the solid material through the discharge container and carrying of the dust particles away from the discharge opening of the discharge nozzle into the dust collection container.

Abstract: A container adapted to include a pressurized medium therein for purposes of dispensing the contents of the container or alternatively, to function as a heat exchange unit to heat or cool beverage or food contained therein. The container housing the pressurized medium includes an over pressure release mechanism which includes a barrier member disposed adjacent a valve stem which when depressed releases the pressurized medium. The valve including the moveable valve stem is carried by a mounting member at least that portion of which carries the valve is moveable outwardly responsive to the pressurized medium exceeding a predetermined pressure internally of the container. Upon such movement, the valve stem contacts the barrier which is stationary with respect thereto and after such contact, further moves the valve stem to activate the valve and release the pressurized medium contained within the container.

Abstract: An extended range proportional valve which can control rates of mass flow over continuous low, intermediate and high ranges has a pilot member mounted on an armature of a solenoid which can be dithered onto and off of a pilot opening in a main valve member which seals a main valve opening to control mass flow rates over the low range by varying the duty cycle and/or frequency of a pulse width modulated current in the solenoid coil. Intermediate and high flow rates are achieved by dithering the pilot valve member with a duty cycle and/or frequency sufficient to raise the main valve member relatively short and relatively long respective distances from the main valve seat.

Abstract: A fluid pump dispenser includes a spring biased pump piston having a generally hollow stem and reciprocable between pressure and return strokes within a pump cylinder therewith defining a variable volume pump chamber for dispensing fluid through a discharge opening at an outer end of the stem. The stem defines a valve controlled discharge passage leading from the pump chamber to the discharge opening. A driver nut may be mounted adjacent the pump piston and include at least one flange engaged with at least one respective spiral turn on a spindle disposed within the pump chamber to thereby rotate the spindle during reciprocation of the pump piston. A dip tube may be disposable within a container and affixed to the spindle for rotation with the spindle. A figurine may be mounted onto the dip tube for complementary rotation with the dip tube and the spindle.

Abstract: Problems are posed by slip prevention particle injection devices by wheels of railway rolling stock. Namely, if the injected quantity of slippage-preventing particles is adjusted so as not to be excessive and to be a suitable quantity, it is not possible to obtain a predetermined injection pressure and it is not possible to inject the particles at the target location. The injector device of the present invention is constituted by providing an air through-flow duct 5 inside a particle retainer tank 1, and connecting an air supply duct 17 to this air through-flow duct 5. In the above mentioned tank 1, in addition to an air inflow duct 6 being provided in the vicinity of the inlet side of the air through-flow duct 5, an air discharge duct 18 is provided in the vicinity of the outlet side of the air through-flow duct 5. This air inflow duct 6 and air discharge duct 18 are connected to the air through-flow duct 5 and one end of these ducts 6 and 18 is open into the tank 1.
