Abstract: A signaling apparatus paces a free pour count and choreographs a movement to stop pouring. The apparatus emits a first signal after an approximately 200-ms time interval and a series of subsequent signals every approximately 400-ms thereafter. The first time interval approximates a first time, measured from a moment the sensor detects the start of the pour, needed to dispense a first unit of beverage through the pour spout, minus a second time needed to react to a signal and stop the pour. The 400-ms time interval approximates the time required to dispense each subsequent unit of beverage through the pour spout. In one embodiment, the signaling apparatus emits sequential pulses according to the pattern Y-Y-Y-Y-G-Y-Y-R, wherein Y is yellow, G is green, and R is red, wherein each pulse represents a quarter-ounce increment, the green pulse represents a standard pour, and the red pulse represents a full pour.

Abstract: A delay flow water reservoir for a clothes dryer cabinet and method of use is provided. The delay flow reservoir has a container having an opening and a cap engaging the opening. The cap has a delay chamber with a drain opening, a seal covering the opening with first and second seal holes, and the delayed flow reservoir.

The method of using the delay flow water reservoir permits the user to fill a container while in an upright position and then moving the delay flow water reservoir to an overturned dispense position. The method permits water to drain into the delay reservoir rather than out the drain opening while the user moves the reservoir into operational communication in the clothes drying cabinet.

Abstract: A device (2) for fitting to the neck of a deformable bottle (4) to give a metered dose of liquid when the bottle is squeezed. The liquid dispensed through outlet (30) has to pass through a metering chamber (34) in which it is directed around or through a freely-moving shuttle (8), movement of the shuttle (8) with the flow being resisted by the creation of a partial vacuum in the expanding control chamber (42) behind the shuttle, so that the rate at which the shuttle moves to the outlet end of the metering chamber (34) to close the outlet (30), and hence the amount of liquid dispensed, is controlled by the rate at which liquid can enter control chamber (42). Because it is configured so that all the liquid enters metering chamber (34) at its inward end, the chamber may fitted either inside or outside the neck of the bottle (4) and the dose may be adjusted by moving the outlet (30) closer to, or further from, the inlet.

Abstract: A solid detergent dispenser for use with a dishwashing machine includes a chamber and a lid. The chamber is configured and arranged to receive a solid detergent having a particular composition. A water inlet receives water from a water source, and the water flows through a tunnel into the bottom of the chamber. The chamber is flooded with water from the bottom to ensure relatively constant erosion of the solid detergent, which ensures that a relatively constant concentration of the solid detergent is used in the dishwashing machine. A water outlet allows water to flow out of the chamber into the dishwashing machine. The water must flow into the chamber faster than it flows out of the chamber to ensure that the appropriate amount of dissolution of the solid detergent occurs. The only valve used in the preferred embodiment is a valve to control the amount of water flowing into the water inlet.

Abstract: A buoyant dispensing device for dispensing a material into a body of water. An inner receptacle contains the material and has apertures to permit the material to escape therefrom. A housing having an outer receptacle houses the inner receptacle therein and has corresponding apertures. The inner and outer receptacles are rotatable and fixable with respect to one another to enable a varying degree of overlap between the apertures to control the amount of material dispensed therethrough. Vanes circumscribe the receptacles and corresponding spokes and guard rings interconnect the receptacles and the vanes and keep the receptacles spaced a predetermined distance from other objects. The vanes absorb an impulse force from the body of water and impart the impulse force to the receptacles in the form of a rotational reaction force whereby the dispensing device rotationally and linearly displaces itself within the body of water.

Abstract: A manually operated dispenser for dispensing single shots of liquid with a built-in extended delay between each manually dispensed shot is described. The dispenser contains a manually operated pump for withdrawing a single shot of liquid from the reservoir of liquid, an outlet through which the pump dispenses the single shot and a reciprocal piston and cylinder assembly on the pump. The piston is ready to dispense the single shot of liquid into the outlet when in a retracted position.

If preferred, upon actuation liquid will flow initially, and then the bell can be made to seal the outlet structure to stop liquid flow thereby simulating a pumping action.

Abstract: A chemical controller device for delaying the distribution of chlorinating chemicals into a swimming pool is disclosed. The chemical controller includes a floating dispenser with an inlet port and an outlet port. The floating dispenser contains the swimming pool chlorinating chemicals. A plug of a suitable chemical which dissolves in the pool water sealably blocks the outlet port and prevent contact between the chlorinating chemicals and the pool water. The chemical plug dissolves in the pool water over a period of time and then starts the chlorination process. The length of the chemical plug determines the number of days before the plug dissolves and thus when chlorination of the pool will commence.
