Abstract: A carbonated beverage is furnished from a source at a first pressure to a reservoir in which a quantity of the beverage is held a second pressure level that is less than the first pressure and greater than atmospheric pressure. When it is desired to dispense the carbonated beverage into a serving container, the reservoir is vented to the atmosphere so that the beverage is dispensed at substantially atmospheric pressure. The amount of carbonated beverage in the reservoir is sensed and when that amount drops below a first level, carbonated beverage is added from the source while the reservoir is vented to the atmosphere. The venting terminates when the amount of beverage in the reservoir reaches a second level. The beverage continues to flow into the reservoir thereafter for a predefined period of time causing the pressure to increase to the second pressure level.

Abstract: An impact absorbing system for a flat switch panel has an impact spacer. The impact spacer, a rigid layer that is fixed to an energy-absorbing layer, attaches to the top surface of a flat switch panel just under the overlay. During a condition of switch abuse, the impact absorbing system disperses the energy from a high impact actuation force over a large area of the rigid layer, which in turn causes a large volume of energy-absorbing layer material to be deformed, directing the otherwise damaging impact away from a raised part of the switch that normally accepts a user provided actuation force. Preferably there is an embossed area in the rigid layer and a pip on the raised part of the switch, both improving the function and tactile feedback of the switch. The most preferred embodiment includes a polycarbonate backer on the bottom of the flat switch panel to additionally protect switch components from being damaged by a high impact actuation force.

Abstract: Liquid material is precisely dispensed to a semiconductor processing tool utilizing closed loop control. In one embodiment, CMP slurry material of known density is supplied from a reservoir/mixing vessel to a dispense module. The dispense module also receives a flow of an inert gas through a gas supply valve. Positive pressure arising within the dispense module due to the inert gas flow causes an outflow of slurry from the dispense module to the CMP platen. The rate of flow of the slurry to the CMP platen over time is determined by monitoring the change (decline) in weight of the filled dispense module. In a similar manner, variation in the rate of flow of slurry over time may be detected by monitoring variation in changes in weight of the filled dispense module over time. A regulator structure in electronic communication with the dispense module and with the gas supply valve receives first signals at different time points indicating the weight change of the dispense module.

Abstract: The present invention relates to improved methods for delivering bioadhesive, bioresorbable, anti-adhesion compositions. Antiadhesion compositions can be made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then used as fluids, gels or foams. By providing a product bag, the compositions can be delivered as gels or as sprays. By dissolving propellant gases in the compositions, the materials can be delivered as foams, which have decreased density, and therefore can adhere to surfaces that previously have been difficult to coat with antiadhesion gels. Delivery systems can also provide mechanisms for expelling more product, and for directing the flow of materials leaving the delivery system. Bioresorbable, bioadhesive, anti-adhesion, and/or hemostatic compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions.
