Abstract: A control mechanism for simultaneously supplying air to a refrigerated compartment in two separate air streams includes a housing having an inlet communicating with first and second outlets. A first valve seat interconnects the inlet and first outlet and a second valve seat interconnects the inlet and second outlet. A unitary valve member rotatably mounted in the housing is movable between a closed condition engaging both of the valve seats to block air flow from the inlet to both of the outlets and an open condition out of engagement with both of the valve seats to permit air flow from the inlet to both of the outlets. A temperature responsive mechanism senses the temperature in the compartment and controls the condition of the valve member in response to the sensed temperature.

Abstract: In a combination faucet device (10) according to the invention, a movable valve member (160) slidingly moves relative to a main casing (30) to change a mixing ratio of high-temperature water supplied from a hot water port (116) to low-temperature water supplied from a cold water port (106). The movable valve member (160) is pressed by a temperature sensitive spring (130) in a first direction while being pressed by a bias spring (150) in a second direction opposite to the first direction. The temperature sensitive spring (130) is exposed to water mixture and varies its spring constant according to the temperature of the water mixture. The temperature sensitive spring (130) accordingly moves the movable valve member (160) in a direction for decreasing the ratio of the high-temperature water to a certain position where the spring force of the temperature sensitive spring (130) balances with the spring force of the bias spring (150), thus allowing water mixture adjusted to a target.

Abstract: A method of transporting material includes forming a structural encasement from the material and applying a force to the encasement to transport the material to a desired destination. The structural encasement allows for the transmission of applied forces through the encasement. A core material may be encased within the structural encasement so that both materials are transported together. Confinement forces are transmitted throughout the structural encasement to maintain the core material encased within the encasement. A preferred apparatus for practicing the method includes an inner nozzle for projecting core material and an outer nozzle surrounding the inner nozzle for projecting a hollow column of encasement material around the core material so that the core material is encased within the column. The outer nozzle further applies force to the column to direct the column and the encased core material to the desired destination.

Abstract: Thermal Exchanger for Beverages is a reusable, attachable cover for a cup type or can type beverage container. The container's contents can be almost any kind of beverage. The contents in the beverage container can be at room temperature or even hot. The beverage is chilled by sucking on the exposed end of a straw like tube the same way as you would suck on a conventional straw. The degree of temperature decrease of the beverage is dependent on the temperature of the beverage in the container, the type of frozen matter used in the retention mass, and the amount of time the beverage remains in the Thermal Exchanger. Within the attachable cover, the straw like apparatus is coiled inside a surrounding envelope containing a freezable gel of the type that is used in various applications such as freezer packs. The entire Thermal Exchanger is placed in a freezer for several hours until the gel is frozen.

Manipulation of the drape is achieved by pushing, twisting, pulling, lifting, etc., on the drape to displace it from the basin. Such movement of the drape may be effected on a continuous and automatic basis, or by manual means using a member or implement to facilitate drape movement. The system cabinet includes a refrigerated compartment for pre-chilling sterile liquid to be used in forming the surgical slush.

Abstract: An internal combustion engine fitting containing a thermostatically controlled valve regulating the flow therethrough is formed by two parts interconnectable by relative rotation through a bayonet type connection. The bayonet connection utilizes two stages wherein the first stage maintains the parts connected but a bypass passage defined between the parts permits the flow of coolant through the fitting around the valve to initially permit the engine coolant system to be filled. After the coolant system is filled, the fitting parts are rotated to a final closed position sealing the bypass passage permitting the thermostatic valve to control flow through the fitting during normal engine operation. The fitting parts remain sealed to the atmosphere during both stages of interconnection.

Abstract: A dual-duct HVAC system for providing a desired comfort level in a room, includes a controller that carries out a simple operation that determines the total open damper positions for dual dampers in a dual duct system to effect a desired air flow. Using the total open damper position information as damper control information, the controller also determines a relative damper position difference required between the two dampers to effect a desired temperature level while also meeting the air flow requirement as determined from the total open damper position information. The combination of the total open damper position information and the relative damper position difference is used as control information to control both dampers. Preferably, the controller gives priority of air flow control over temperature control by determining a valid damper position difference range for use in conjunction with the total open damper position information.

Abstract: A tempered water mixing system for applications such as emergency drench shower and eyewash stations, wherein the mixing system includes back-up control valves to ensure a substantial water flow without risk of user scalding in the event of malfunction of a main thermostatic mixing valve. The main mixing valve thermostatically blends cold and hot water supplies to provide a tempered discharge outflow at a selected temperature. A temperature limit control valve detects the discharge outflow temperature and responds to an excess temperature condition to modulate hot water flow in a manner reducing discharge temperature. A flow limit control valve detects the pressure differential between the discharge outflow and the cold water supply, and responds to a low flow condition represented by a high pressure differential to permit a make-up bypass flow of cold water past the main mixing valve.
