  • Patent number: 11867181
    Abstract: A refrigeration system includes a compressor having a hermetically sealed housing and a compression mechanism which is positioned inside the housing; a condenser which is fluidly connected to the compressor; an evaporator which is fluidly connected between the condenser and the compressor; a magnetic coupling having a drive coupling half positioned outside the housing and a driven coupling half positioned inside the housing and separated from the drive coupling half by a separation wall portion of the housing; and a fluid conduit for communicating a portion of liquid refrigerant from the condenser to an inside surface of the separation wall portion. During operation, the liquid refrigerant from the condenser is evaporated on or adjacent the inside surface of the separation wall portion to thereby dissipate heat generated by magnetically induced eddy currents in the separation wall portion.

  • Patent number: RE43398
    Abstract: The present invention is directed to a much safer and less expensive way of providing portable oxygen from a gas concentrator for patients who do not want to be tied to a stationary machine or restricted by present oxygen technology. The present invention involves a home liquid oxygen ambulatory system for supplying a portable supply of oxygen, where a portion of the gaseous oxygen output obtained from an oxygen concentrator is condensed into liquid oxygen. The system includes an oxygen concentrator which separates oxygen gas from the ambient air, a condenser in communication with the oxygen concentrator for receiving and liquefying the oxygen gas flow, a cryocooler associated with the condenser, and a first storage dewar in fluid communication with the condenser and adapted to store the oxygen liquefied by the condenser, the first storage dewar including means for transferring liquid oxygen from the first dewar to a second dewar for storing a quantity of oxygen suitable for moveable oxygen treatment.
