  • Patent number: 6904769
    Abstract: In an ejector-type depressurizer, a nozzle arrangement converts pressure energy of refrigerant supplied from a radiator into velocity energy to depressurize and expand the refrigerant, and a pressurizer arrangement mixes the refrigerant discharged from the nozzle arrangement with the refrigerant drawn from an evaporator and converts the velocity energy of the refrigerant discharged from the nozzle arrangement into pressure energy to increase the pressure of the mixed refrigerant discharged from the pressurizer arrangement. The pressurizer arrangement includes a refrigerant passage that conducts the refrigerant supplied from the nozzle arrangement and the refrigerant supplied from the evaporator, and the refrigerant passage includes a refrigerant passing zone, through which the refrigerant from the nozzle arrangement and the refrigerant from the evaporator mainly pass during operation of the ejector-type depressurizer.

  • Patent number: 6631616
    Abstract: A biopharmaceutical cryopreservation system includes a container having an outer surface area with the container being adapted to contain a biopharmaceutical material for freezing and thawing therein. The container may be received in a cryocooling enclosure having an interior cavity configured to receive it. The cryocooling enclosure includes at least one heat transfer surface configured to contact the outer surface area of the container when the cryocooling enclosure interior cavity receives the container. Also, a cryocooler is thermally coupled to the cryocooling enclosure and is configured to flow a fluid to the at least one heat transfer surface to control the temperature of the heat transfer surface and the biopharmaceutical material within the container. The fluid is isolated from contacting the container. Further, a temperature sensor is thermally coupled to the cryocooling enclosure, the at least one heat transfer surface, the fluid and/or the cryocooler.

  • Patent number: 5348223
    Abstract: A method and an apparatus for producing a continuous liquid flow at a controlled temperature. The apparatus includes mixers (1, 2) which, upstream, are connected to a supply conduit (3) for hot liquid under pressure and a supply conduit (4) for cold liquid under pressure. Each respective mixer has an outlet (5, 6) connected to a common discharge conduit (9) by a first outlet conduit (7, 8). The common conduit (9) is provided with a tap (10) disposed downstream of the interconnection of the outlet conduits with the common conduit (9). The temperature of the liquid which is to be discharged through conduit (9) is adjusted in that hot and cold liquid are mixed in the mixers from which the liquid is supplied to the common conduit (9).

  • Patent number: 5303864
    Abstract: In an expansion valve for controlling the flow rate of a refrigerant supplied to an evaporator of a refrigerating system, a temperature-sensing chamber is provided to sense the temperature of the refrigerant returning from said evaporator and to actuate a valve mechanism in order to regulate the flow of refrigerant supplied to said evaporator. An adsorption means provided inside the temperature-sensing chamber to adsorb a liquefied part of a gas charge within said chamber in order to hold said liquefied part away from warm wall parts inside said chamber. In addition, or as an alternative, said temperature-sensing chamber is separated from a return passage of said refrigerant by thermal-transfer-delay means for delaying the thermal transfer of a temperature change from the refrigerant to a sealed charge within said temperature-sensing chamber. Said thermal-transfer-delay means can be made as a flow restrictor for supressing an excessive flow between said chamber and said return passage of the refrigerant.

  • Patent number: 4996909
    Abstract: An electronic measurement, data storage and readout system utilizing a programmable processor and controller to manipulate data measurements from a transducer is disclosed. Means are provided for electronically safeguarding the stored data.In the preferred embodiment means are also provided for reading out the data directly to a dedicated printer for producing graphical representations of the data and for converting the data to frequency-shift keyed signals which can be transmitted over telephone lines to the dedicated printer. A redeployment station is provided to reinitialize the programmable processor and controller.

  • Patent number: 4614088
    Abstract: An icemaker including a freezer mold having a plurality of partitioned walls disposed within the mold to define a plurality of cavities in which water is to be frozen to form ice pieces having an edge portion. There is provided a stripper member disposed longitudinally along one side of the mold and having a portion thereof above the cavities and said portion having an upwardly depending ridge. The ejection of ice pieces from the mold is provided by a rotating ejector for rotatably moving the ice pieces to above the cavities and to continue rotating the ejector and moving the ice pieces onto the stripper member such that the edge portion of the ice pieces engage the upwardly depending ridge and are retained thereby. Continued rotation of the ejector pivots the ice pieces upwardly about the edge portion and past the vertical whereupon the ice pieces tumble off the stripper member laterally outward of the mold.
