Abstract: The distributor comprises a carriage (2) intended to contain a stack of sheets. This carriage (2) is mounted to slide between two stop positions on a support plate (7) thanks to ball bearings (6). The support plate (7) exhibits a slightly elevated rear portion (9) with a front step part (9a). By making a back and forth movement with the carriage (2), the bottom sheet of the stack is separated from the stack and held by the step (9a) on the front part of the plate (7) making it easy to take notes with but a single hand.

Abstract: A pressure monitoring system monitors the pressure of hot melt adhesive in a dispenser in an adhesive dispensing system. The dispenser includes a valve and the dispensing system further includes a controller for opening and closing the valve for dispensing pressurized hot melt adhesive from the dispenser. The pressure monitoring system includes a sensor circuit which develops an electrical pressure signal reflective of the pressure of adhesive in the dispenser and a pressure monitor circuit which monitors the electrical pressure signal when the dispenser valve is open. A pulse masking circuit is interposed between the pressure sensor circuit and the pressure monitor circuit to modify the signal produced by the pressure sensor circuit to mask out a transient leading edge, reduced pressure pulse appearing in the electrical pressure signal each time the valve is opened.

Abstract: An electronically controlled, pneumatically actuated pumping system is provided that is especially designed for the precision dispensing of liquids. The system includes a positively actuated inlet valve, and a small-diameter, long-stroke pumping piston that is physically stopped at each end of its stroke. The unique inlet valve and piston enable the system to repetitively dispense metered volumes of fluid at better than one tenth of one percent accuracy. A unique calibration mechanism and detachable dispensing head allow for the rapid disassembly, cleaning, and reassembly of the system. An alternative embodiment of the pumping system incorporates a plurality of dispensing nozzles controlled by a single inlet valve and pumping piston combination. The dispensing unit may be shiftably mounted on a vertically oriented stand, and may be automatically shifted upwardly as fluid is dispensed to minimize splashing and atomizing of the dispensed fluid.

Abstract: A coin bank for separating a group of coins, forming the coins into a moving file, and for sorting the coins. The bank has a housing with an inlet for receiving a group of coins, coin bins for receiving coins of different diameters, a mechanism for separating individual coins from a group deposited into the inlet and for advancing the separated coins in a moving file, and a mechanism for receiving coins from the moving file and for sorting the coins in respective coin bins. The housing has a transparent wall disposed so as to allow coins in the moving file to be viewed therethrough, to provide the bank with a unique visual effect.

Abstract: A pressure multiplying dispenser for delivering fluid, preferably as a spray to the atmosphere, from a source of fluid, preferably a spray bottle, is described. The dispenser includes in combination a hollow cylindrical member, a nozzle delivery tube within the cylindrical member and a hollow actuator piston slideable within the cylindrical member which acts to multiply the pressure of a squeeze applied to the spray bottle.

Abstract: Material dispenser apparatus includes a dispenser roll and dispenser roll cleaning brush mounted within the bottom discharge opening of a material receiving hopper for direct contact by the material in the hopper. The brush, being directly disposed to the material in the hopper, aids in displacing the material in the hopper toward the dispenser roll and compacting the dispenser roll with such material. Also, the brush clears the material from the dispenser roll as the brush and dispenser roll come into contact with each other. The speeds of rotation of the brush and dispenser roll are desirably each controlled independently of the other to permit them to be simultaneously rotated in the same direction but at different rpm for controlling the rate and size of material being dispensed. A material agitator may be provided in the material receiving hopper for working the material down within the hopper into contact with the surfaces of the dispenser roll and brush which are exposed to the material in the hopper.

Abstract: The present disclosure is directed to a container for dispensing semi-solid products consisting of a cylindrical body having a rounded closed applicator end and an opposite open ended base. A dome shaped product discharge piston is movable through the body beneath the storage chamber driven by a piston drive screw having two flat and two arcuate sides opposed each other for driving the piston upwardly in the cylindrical body to discharge the product. A dial and screw drive ratchet is positioned within said container and has a manually rotatable apron for advancing the screw shaft and piston and is positioned beneath said piston. A base and wrench is positioned at the open end of the container for positioning and supporting the dial and screw drive ratchet to permit the drive screw to be rotated by the dial apron while permitting axial motion of the drive screw through the base and wrench to drive the piston upwardly.

Abstract: A cryogenic liquefied pump system which includes a pump having a drive motor, bearings, a drive shaft, and an impeller adapted to be disposed in a vessel storing a cryogenic liquid. An outer insulating tank is mounted in the vessel and an inner insulating tank is mounted inside the outer insulating tank, with a vacuum layer being interposed between the inner and outer insulating tanks. An inner side of the inner insulated tank, in which the motor and bearings are arranged, is maintained at a room temperature, with a tip portion of the inner insulating tank being formed into an outer case extending into a cryogenic region outside of the outer insulated tank.

Abstract: The portable, light-weight pumping mechanism is for transferring and mixing two fluids from a portable fluid container having a top portion of predetermined dimensions and having an inlet port. The portable pumping mechanism is comprised of a base cover member having an aperture therethrough and having a downwardly extending circumferential lip adapted for securing the pumping mechanism to the top of the portable fluid container. A frame structure is mounted to the top of the base cover member and a pair of interconnected elongated pneumatic pumps are mounted to the frame structure. One of the pneumatic pumps is connectable to a compressed air source. A downwardly extending pickup conduit protrudes through the aperture in the base cover member to sealingly engage the inlet portion of the container and it is further in communication with one of the pumps for removing fluid from the portable fluid container.
