  • Patent number: 4651813
    Abstract: A process for the setting of a constant temperature for a fluid, and furtmore, to a thermostat for implementing the process. The constant temperature is set by the heating up of the fluid during its flow through a heat source. The fluid, prior to the setting of the constant temperature, is initially cooled down to a lower temperature, such that the temperature difference which is reached between the constant temperature and a lower temperature, is higher than the temperature-overshooting range of the cooling regulating circuit. These measures simplify the setting of the constant temperature inasmuch as only the heat source need be equipped with a high-performance regulator. Through the cooling section which is connected ahead of the heating element, there is maintained a minimum temperature differential.

  • Patent number: 4547977
    Abstract: The circulation of heat transfer fluid through the low temperature heat exchanger in the temperature control system of a freeze dryer is selectively increased when the temperature of heat being applied to the product shelf assembly in the freeze dryer exceeds the desired temperature. Preferably, a servo-controlled mixing valve selectively bypasses the low temperature heat exchanger so that the rate of cooling is very precisely adjusted without requiring the heat exchanger refrigeration unit to be cycled on and off. Since the refrigeration unit operates continuously, the reliability and operating lifetime of the refrigeration unit is increased. Moreover, the heat exchanger temperature is maintained at a minimum value. Preferably, the servo-control for the mixing valve includes a digitally controlled stepping motor and the adjustment of the mixing valve is sensed by a linear voltage displacement transducer. To prevent short cycling and oscillation, a dead band is introduced in the servo-control loop.

  • Patent number: 4351851
    Abstract: A method for freeze-stabilizing wine and a system for carrying out this method are described. The method is of a type in which the wine is first chilled so that ice crystals are formed in the wine while the wine is still pumpable, whereupon the wine is conveyed to a residence tank in which tartrate crystals are formed. The wine is then heated to melt the ice crystals, whereupon the tartrate crystals formed are removed from the wine. The method according to the invention is characterized in that the wine is conveyed continuously to and from the residence tank, where the wine is agitated in such a way that there is maintained a homogeneous suspension of ice crystals and tartrate crystals in wine. It is advantageous to stir the wine with a horizontally pivoted stirrer which rotates at a relatively low speed. Suitable operating conditions are obtained if the wine is first chilled to a temperature which is 0.2.degree. to 5.degree. C.

    Abstract: A heat receiver is provided comprising a housing through which the breathing mixture passes in one direction and through which the exhaled breath passes in the opposite direction. The housing contains heat conductive elements through which the breathing mixture and exhaled breath pass and spacers positioned one between each pair of adjacent heat conductive elements. The spacers are poor heat conductors and non-hygroscopic to minimize moisture retention. In use, exhaled breath warms the heat conductive elements sequentially so that each element will be slightly cooler than the last element exposed to the exhaled breath. There will be minimal heat stored in the spacers and the moisture content of the exhaled breath tends to be carried through the device so that upon drawing breathing mixture through the device a substantial part of the sensible heat originally in the exhaled breath will be reclaimed by the breathing mixture. The latent heat originally in the exhaled breath will be lost.
