Abstract: 1494019 Refrigeration THERMO KING CORP 15 Dec 1975 [24 Dec 1974] 51188/75 Heading F4H [Also in Division G3] A refrigeration system for the storage space 13 of a transport vehicle comprises an evaporator 16, over which air is circulated by a fan 14, and temperature sensors 28, 29 located at regions at which the air flows into and out of the space 13. A thermostatic control arrangement (see Division G3), has an adjustable set point and movement of the set point above or below a given point, e.g. 20 F., causes the refrigeration system to be controlled in response to the first or second sensor, respectively. When the set point is above the given point, the sensor 28 causes either a heater 15 to be activated or causes closure of a valve 25 in the suction line from the evaporator to produce a step-down reduction in the refrigeration capacity followed by actuation of a modulating valve 26, connected in parallel with the valve 25, as the temperature of the air entering the chamber 13 approaches the set point. When the set point is below the given point, the sensor 29 is operative to control the valve 25 and a liquid line valve 22 so that there is no step-reduction or modulation of the refrigeration capacity.

By the inclusion in the third layer of a metal having the property specified, the tunnelling junction which would otherwise be formed by an intermediate oxide layer 48 developed during the deposition process is destroyed. The various layers are deposited by vacuum deposition through appropriate masks, the oxide layer being formed by an R.F. oxidation process. Insulation between the second and third metal layers is provided by a layer 40. The superconductive current limit across a contact so formed may be raised by sputter etching an oxidized surface before metallic deposition. The major component of the metal layers is lead. The second metal layer may include aluminium, tin, niobium or indium, but is preferably a ternary alloy of lead indium and gold. An alloy of lead and indium may be used for the third metal layer with the indium deposited after the lead to prevent breakdown of the Josephson junction between layers 34 and 36. Suitable free energy of oxide formation metals included in the fourth metal layer are indium, gallium, tin, aluminium, lanthanum and manganese. Gold may be included in each metal layer to prevent adverse stress relaxation effects.
