  • Patent number: 5984196
    Abstract: An air vent that automatically opens and closes in response to changes in the ambient air temperature. The air vent includes a housing, a louver frame mounted to the housing and a series of vent louvers pivotally mounted to the frame. The louver frame includes a cam member for automatically pivoting the louvers between an open position and a closed position in response to ambient air temperature changes. The cam member includes a spring fixedly mounted at one end to the housing and mounted at the other end to a camming bar, which is mounted to the louvers. This spring is formed of two different types of metals which react to changes in the ambient air temperature. More specifically, the metals are chosen so that the spring expands as the temperature increases to rotate the cam bar in one direction and incrementally open the louvers, and contracts as the temperature decreases to rotate the cam bar in the reverse direction and incrementally close the louvers.

  • Patent number: 5931003
    Abstract: A method and system for electronically controlling the location of the formation of ice within a closed loop water circulating unit and efficiently harvesting ice includes a method and system for making ice using supercooled water. When a desired degree of supercooling is reached in the closed loop water circulating unit, a pump associated with the ice-making machine is stopped so as to initiate ice seeding on the ice mold. After the pump is restarted, the supercooled water flows over the seeded molds to rapidly form ice on the ice molds. The completion of ice formation in the mold is sensed by reservoir water temperature, water level, timing or other inputs to enable a controller to automatically control a harvest cycle timely. A method and system is also provided for improving the clarity of the ice.

  • Patent number: 5816060
    Abstract: An air flow control arrangement for a side-by-side refrigerator which results in temperature variations, both spatial and temporal, of approximately about F. in the fresh food compartment, is described. Such air flow control also is believed to even further reduce the internal "sweat" in the fresh food compartment. In one embodiment, and with respect to a side-by-side refrigerator, the middle duct in the center mullion wall is closed off, and a duct is added in the center mullion wall, or could be installed as a separate duct outside the mullion, connecting a supply port in the top, back, left hand corner in fresh food compartment to a position in the evaporator chamber. The added duct also seals off direct airflow between the evaporator chamber and the fresh food compartment.

  • Patent number: 5765385
    Abstract: A self-cooling beverage container system. The system includes a can, and an external chamber coupled to the bottom of the can for containing compressed gas therein. Helical tubing in the form of a single or double helix resides within the can. A first open end of the tubing is disposed in communication with the external chamber, and an opposing terminal end of the tubing is closed, preferably being accessible with a pull-tab as presently known in the field for opening a vessel responsive to pulling action by a user. When the terminal end of the tubing is opened it communicates with atmosphere, permitting the compressed gas to flow from the external chamber through the tubing and into atmosphere. The gas expands as it flows, thereby withdrawing heat from the surrounding beverage in which the tubing is submerged to cool the beverage.

  • Patent number: 5600963
    Abstract: An indoor unit of an air conditioning system includes front and rear cases joined together to form a space in which a heat exchanger, fan, and fan motor are housed. A grill member hingedly mounted on the front case has a front air intake opening formed therein. A top air intake opening is formed in an upper side of the rear case. A filter is mounted on a rear side of the grill member to extend across the front air intake opening. An upper portion of the filter underlies the top air intake opening. Edges of the front and rear case overlap one another, and one of those edges forms a slot in which the other edge is received. Boards for carrying electrical components are mounted in an out-of-way manner to minimize the space taken up.

  • Patent number: 5593088
    Abstract: A heating device is provided for motor vehicles with a water-cooled internal combustion engine, which heating device has a heat exchanger which is acted on by the cooling water circuit of the internal combustion engine on the one hand and by an auxiliary heating unit which is independent of the internal combustion engine on the other hand. A thermostatically activated switching element causes the hot water to flow via the heat exchanger below a temperature prescribed by the thermostat, when the auxiliary heating unit is switched on, and to flow additionally via the internal combustion engine above this temperature, and causes the engine cooling water to flow via the heat exchanger when the auxiliary heating unit is switched off. In order to achieve low production costs and a large degree of robustness of the switching element it is equipped with a non-return valve whose blocking direction is directed from an outflow chamber to an inflow chamber.

  • Patent number: 5564627
    Abstract: The invention relates to a heating cycle system of a motor vehicle which includes the vehicle internal combustion engine, a heating device which is independent of the engine, an interior heat exchanger, a circulating pump, and a bypass line which connects a return line to a flow line. According to the invention the circulating pump is driven by a reversible electric motor and is used as a control element for selective operation of a small cycle including only the heating device and the vehicle heat exchanger or a large cycle which also includes the internal combustion engine. The direction of operation of the circulating pump controls a valve which directs fluid to either the small or the large cycle.

  • Patent number: 5551240
    Abstract: Sterile surgical fluid is maintained at substantially its freezing temperature to prevent both melting and formation of solid ice pieces in surgical slush and to provide a supply of near freezing fully liquid phase sterile fluid as required. Slush is initially formed in a refrigeration mode wherein a basin containing sterile fluid medium is cooled to well below the freezing temperature of the medium to thereby rapidly lower the medium temperature. Upon formation of the slush the system is placed in a maintain mode wherein the container temperature is kept at or near the freezing temperature of the medium to selectively provide either slush or near freezing liquid. In the preferred embodiment the maintain mode is effected by electrically energizing one or more thermoelectric modules and de-energizing a refrigeration system in which the refrigerant fluid is passed through an evaporator disposed in thermal energy transfer relation to the basin.

  • Patent number: 5487277
    Abstract: Energy efficient independent temperature control is achieved in refrigerators by minimizing system run time. A freezer thermostat activates the refrigeration system when the freezer compartment requires cooling and a fresh food thermostat which controls a damper between the two compartments. The two thermostats are operatively connected so that the freezer thermostat is prevented from switching off whenever the fresh food thermostat calls for cooling in the fresh food compartment. Thus, only the freezer thermostat is able to activate the refrigeration system, while either of the thermostats can inactivate the system.

  • Patent number: 5363659
    Abstract: Apparatus for continous production of flake ice comprises one or more refrigerated discs mounted on a hollow shaft. Each disc rotates in the vertical plane and includes a plurality of narrow internal channels which extend substantially over all of the operative portion of the disc and are of substantially equal length. The discs form the evaporator of a refrigeration circuit, and an evaporative refrigerant is circulated to the channels in each disc via the hollow shaft. During each cycle, water is applied to both external flat surfaces of each disc at a first angular location and the film of water which adheres thereto freezes as the disc rotates. The ice sheet so formed is removed from both sides of the disc at a second angular location by scraper blades.
