  • Patent number: 6578741
    Abstract: In a dispenser, particularly an atomizer, which is used for flowable substances, particularly pharmaceuticals, use is made of a pump, which must be actuated one or more times for priming purposes. Its discharge nozzle (14) is covered by a protective cap (38), which is suitable to collect and store the medium, which is discharged during the priming strokes and before the start of the useful strokes. During the priming strokes the protective cap (38) is secured on the dispenser (11). This is brought about in that a locking (40) for the protective cap is only released when the priming strokes have been performed. This can take place by electrical actuation or by material change under the influence of the medium to be discharged. According to a variant the protective cap is not itself locked, but an actuation locking takes place if the protective cap has not been fitted for the priming strokes.

  • Patent number: 5988461
    Abstract: A dispenser for volumetrically controlling the amount of lubrication which is fed into the shot sleeve of a die casting machine. Lubrication beads are fed into a hopper. The beads gravitationally travel through a port in the base of the hopper and into a screw extruder. The beads are then moved through a screw extruder both mechanically and pneumatically. The beads are moved mechanically by the rotation of the screw shaft in the screw extruder with a rotary motor. The beads are moved pneumatically by injections of air fed into the screw extruder. The air flow serves the additional purpose of cooling the beads as they move along the screw feeder so that they do not melt and become coagulated. The rotary motor and the air flow are both activated and deactivated by the use of adjustable timers. The timers are synchronistically metered so that the lubricating beads move through the shot bead dispenser and into the die casting machine at predetermined rates.

  • Patent number: 5464120
    Abstract: A frozen dessert dispensing apparatus is provided with a metering chamber having a predetermined volume into which a frozen dessert product is issued at a uniform constant rate from a bulk source. The time period required to fill the chamber volume determines a characteristic viscosity value of the dessert product which is advantageously used to time the flow of additional frozen dessert product from the source into and through the chamber to a selected point. The total time required to dispense a desired volume is based upon the viscosity measurement. A reciprocating piston arrangement provides gating of the frozen dessert product from the bulk source when in a first position and further acts to extrude frozen dessert product from the metering chamber when set in motion under the command of a controller. The piston arrangement includes a compressible plunger portion which deforms as necessary to prevent accidents or other mishaps from occurring in pinch-off regions of the apparatus.

  • Patent number: 5271526
    Abstract: Programmable additive controllers control flow of fluid additives from a fluid supply line. A flowmeter is connected to the solenoid control valve for measuring flow of fluid. A controller opens and closes the control valve. The control valve is positioned downstream from the flowmeter, leaving the meter full upon shut off. A settable input controls cyclic operation of the controller. The controller further incorporates an input for required quantities of additive to be added on each cycle. A comparator in the controller compares a required quantity with signal output indicating flow through the flowmeter. The difference, if any, between actual flow and target flow is continuously sent, and the target flow is continuously adjusted up or down when necessary to compensate for the previous difference. The comparator connects to a closing control for closing the control valve and preventing further flow of additive when the cumulative flowmeter output signal approaches the requirement.
