  • Patent number: 5718356
    Abstract: An apparatus for dispensing hot melt adhesive or other materials. The apparatus includes a container and an outlet. The container has a first material (the material to be dispensed) disposed therein, which changes from a solid state or a state of high viscosity to a state of low viscosity when heated above a predetermined temperature. The container also has a second material disposed therein, which is adapted to be heated above a predetermined temperature when subjected to microwaves for at least a predetermined period of time. The second material can be an inner layer of the container, can be applied to a microwave transparent sheet surrounding the first material, or can be embedded in a silicone tube surrounding the first material. The second material is in a heat transfer relationship with the first material. While the dispenser is being subjected to microwaves, the second material converts the microwave energy into heat and transfers the heat to the first material.

  • Patent number: 5494194
    Abstract: A reciprocating piston with an integral valve moves in a first direction within a cylinder to pressurize viscous material contained therein, such as ice cream or the like, thereby pushing it out of a dispensing nozzle located at one end of the cylinder while simultaneously extracting viscous material from a collapsible container into the other end of the cylinder by suctioning the material from the container. When the piston moves in a second direction, the integral valve opens to allow the piston to pass through the previously suctioned viscous material then within the cylinder. The dispensing nozzle includes a normally closed, spring-biased valve opened by the force of the pressurized material, closing of the valve being assisted by a transient suction force occurring as the valved piston begins to move in the second direction through the material.

  • Patent number: 5431302
    Abstract: An improved apparatus and method is provided for accurately dispensing a preselected volume of liquid. A flowmeter is provided to generate signals proportional to the flow of liquid through a faucet. A programmed microcomputer receives the flowmeter signals and controls the faucet. The residual volume of liquid (spill), which was dispensed after the faucet was last commanded to close, is stored and averaged with additional, previously stored spill amounts by the microcomputer. The average spill volume is used to anticipate the spill for the forthcoming pour. When the cumulative volume of liquid dispensed is equal to the preselected volume less the anticipated spill volume, the microcomputer signals the faucet to close, resulting in an accurate pour. In a another aspect, an improved beer dispensing head is provided. A spring-loaded conventional tap handle activates a sensor means in the head.
