Abstract: An inflation control apparatus includes seal heads at ends of a container liner on a rack; a rotary inflation connector includes a static component and a rotating component. The rotating component is connected with the seal head; an inflation core tube is in the container liner, air holes are in the inflation core tube, and the two ends of the inflation core tube are connected with the static component of the rotary inflation connector respectively. A temperature and pressure sensor is in the container liner; an air compressor provides air for an air heater, the air heater introduces the heated air into an air inlet of the inflation core tube, an air outlet of the inflation core tube is connected with an air inlet of a flow regulating valve, and an air outlet of flow regulating valve is connected with an air inlet of the air compressor.

Abstract: An apparatus 2 comprising a cryogenic chamber 4 and a galvanic input interface 6 to the cryogenic chamber 4 configured to receive a lower amplitude electric current 8. A converter 10 is located within the cryogenic chamber 4 and configured to convert the lower amplitude electric current 8, provided by the galvanic input interface 6, to a higher amplitude electric current 12 for supply to a load 14 within the cryogenic chamber 4. A controller 16 is configured to control the converter 10 and to detect the onset of quench by comparing the duration of the charge/discharge cycle of the convertor with a stored value. The controller 16 may also compare an instantaneous value of load current with a stored value of load current.
