Abstract: A sound damping wallboard and methods of forming a sound damping wallboard are disclosed. The sound damping wallboard comprises a gypsum layer with a gypsum surface having an encasing layer. The encasing layer is partially removed to expose the gypsum surface and form a gypsum surface portion and a first encasing layer portion on the gypsum layer. A sound damping layer is applied to the gypsum layer to cover at least part of the gypsum surface portion and the encasing layer portion.

Abstract: A dispensing device that dispenses a predetermined volume of fluid into a receptacle has a valve that controls the flow of the fluid through the device. The valve is pre-heated to a calculated operating temperature before dispensing operations begin. Once the temperature of the valve reaches the calculated operating temperature, the device begins dispensing the fluid. The valve is maintained at that calculated temperature during dispensing operations.

Abstract: A dispensing apparatus for dispensing predetermined volumes of fluid into receptacles receives the fluid to be dispensed from a fluid supply into a reservoir. A fill tube is connected to the fluid reservoir such that it forms a closed loop with the reservoir. The fill tube minimizes the fluid turbulence that occurs inside the reservoir while the reservoir is being re-supplied with fluid from the fluid source. Additionally, the fill tube holds the predetermined volume of fluid to be dispensed into the receptacle. A fluid level sensor is disposed along the fill tube to control the volume of fluid flowing into or out of the fill tube, while a timer controls a dispense valve to meter the flow of fluid into or out of a dispense tube.

Abstract: A fluid dispensing apparatus is configured to dispense a predetermined volume of fluid, and includes a fluid reservoir to hold a fluid to be dispensed, a dispense tube to dispense the fluid, and an elevator mechanism. The fluid reservoir receives a fluid from a fluid supply. A dispense tube has a dispense outlet, and is connected to an outlet port on the fluid reservoir. The elevator mechanism changes a relative vertical displacement between the dispense outlet and the outlet port. Particularly, a processor controls the elevator mechanism to raise the dispense tube to a raised filling position to prevent fluid flow from the dispense outlet, and lower the dispense tube to a lowered dispensing position to dispense the fluid.

Abstract: A fluid dispensing apparatus includes a fluid reservoir comprising a flexible bag-like enclosure. The fluid reservoir includes a discharge valve connected to a fluid output for dispensing fluid from said fluid reservoir. An electronic controller selectively opens and closes the discharge valve to dispense a predetermined volume of fluid from said fluid reservoir. The fluid reservoir is flexible so that it expands and contracts to maintain the internal pressure of the fluid reservoir constant. In an alternate embodiment, the fluid reservoir has a rigid wall and is provided with an external bladder which expands and contracts to maintain the internal pressure of the fluid reservoir constant. The fluid dispensing apparatus can be configured either as a volumetric filler or as a time pressure filler.

Abstract: A fluid dispensing apparatus includes a fluid chamber and a fill tube which forms a closed loop with the fluid chamber. A pair of level sensors are disposed adjacent to the fill tube. Fluid is directed from the fluid chamber into the fill tube through a fill valve. When the fluid level in the fill tube rises to a first predetermined level, the fill valve is closed and a discharge valve is opened to dispense the contents of the fill tube into a container. When the level of the fluid in the fill tube drops to a second predetermined level, the discharge valve is closed and the cycle is repeated.

Abstract: A fluid dispensing apparatus having no moving parts in contact with the fluid includes a fluid chamber and a measuring cup having an open top disposed in the fluid chamber. The fluid chamber is connected to a fluid source which supplies fluid to fill the chamber to a pre-determined level above the top of the measuring cup. As the fluid chamber is being filled, the fluid overflows and fills the measuring cup. A first sensor indicates when the fluid reaches the pre-determined level above the top of the measuring cup and stops the flow of fluid into the fluid chamber. A drain, which is responsive to the first sensor, drains fluid from the fluid chamber until the fluid level drops to a predetermined level below the top of the measuring cup. As the fluid level in the fluid chamber recedes, a pre-determined volume of fluid is captured in the measuring cup.
