[Also in Group XIII] Apparatus for testing indicating instruments in varying temperature conditions comprises an enclosed thermally-insulated space with thermostatically-controlled heating means to maintain an upper extreme temperature in one part and thermostatically-controlled cooling means to maintain a lower extreme temperature in another part thus establishing a continuously varied temperature distribution between these parts with means for supporting instruments under test and for moving them from a region at any temperature to a region at any other between the extremes. The space between the outer and inner walls 1, 2 of an upright cabinet of square cross-section is packed with thermallyinsulating material and a refrigerator 6 attached to the outer wall supplies cold fluid to pipes 5 inside the cabinet near the bottom under the control of a thermostat 7 set, e.g. to maintain a temperature of - 55‹ C. and supplies hot fluid through pipes 9 to pipes 10, 11, respectively, outside and inside the cabinet near the top, the distribution of hot fluid between the pipes 10, 11 being controlled by a valve 12 itself controlled by a thermostat 13. The thermostat 13 is set to maintain a temperature of, e.g., 100‹ C. and also controls the supply of mains current to a heating element 14 to supplement, if necessary, the heat supplied by the fluid. The thickness of the insulation is conveniently graded so that the temperature variation from top to bottom is linear. Trays 17, which can be positioned by chain conveyers 18, accommodate the instruments to be tested which are inserted through a hatch in one side of the cabinet at a height at which the inside and outside temperatures are approximately the same and upper and lower inspection windows are also provided in the same wall. In order to control the humidity conditioned air is supplied through an inlet pipe 19, a corresponding outlet pipe 20 being provided.

Abstract: 453,415. Meshing-screw pumps. LEISTRITZ, P., and BURGHAUSER, F., 29, Markgrafenstrasse, Nuremberg, Germany. May 20, 1936, No. 14288. Convention date, April 17. [Class 110 (ii)] The peripheries of the threads are tapered at a, b, opening towards the pressure side of the pump, so that oil under pressure is forced in between the peripheries and the casing bore. Oil passes through the bore h into the thrust-bearing chamber i and is discharged along the bearings G, F, to the suction chamber. Recesses d ... g are cut in the bearings on one side of each so that the oil pressure along the surface 1-3 is represented by a triangle 1, 2, 3, while on the opposite side the pressure is represented by a triangle 5, 6, 7. The excess pressure equal to area 2, 3, 4, counteracts a lateral thrust on the spindle S<2>. In the pump shown in Fig. 8 the spindle B is driven from the spindle A by the meshing helical threads. To prevent axial movement of the spindle B, two collars q cooperate with a conical collar r on the spindle A. The tapered parts a, b, may be arranged on both edges of the peripheries of the threads, for reverse running.

May 14, 1931, No. 14311. Convention date, May 14, 1930. Addition to 341,732. [Class 40 (v).] Changes in the frequency of received alternating current are detected by a valve oscillator 14 with its frequency fixed by a long line 18 to a value outside the frequency range of the signals, which are indicated by the changes in direct energy supplied to the valve. As shown, two oscillators 14, 16 have their frequencies fixed by long lines 18, 20 to values on either side of the frequency range and are coupled together to oscillate at a common frequency intermediate their natural frequencies, and the signals are applied by a coil 30 to force the common frequency of the oscillators to vary with the frequency modulation. The signals are passed through an amplitude limiter 6 before application to the oscillator. The oscillators may be arranged not to oscillate until signals are received, and a number of valves in cascade may be used. According to a modification, an aperiodic long line is used and couples tuned circuits in the anode and grid circuits of the oscillator, Fig. 2 (not shown).
