Abstract: 700,838. Measuring radiation photo-electrically. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 24, 1952 [Nov. 29, 1951], No. 28044/51. Class 40 (3) In a photo-electric pyrometer in which the photo-electric cell is fed with an alternating voltage so that the output may be amplified in an A.C. amplifier, the amplitude of the alternating voltage is made sufficiently large to drive the cell to saturation so that its output is a square wave the intensity of which depends on the intensity of incident illumination. As shown the photo-cell PE receiving radiation from the hot body is fed with an alternating voltage of sufficient amplitude to saturate it by a transformer T. The signal developed across resistor R1 is amplified in resistive capacity coupled valves V1, V2 and the amplitude of the square wave output is measured by diodes D1, D2 which provide a direct voltage proportional to the peak to peak amplitude of the signal. The signal is applied to the grid of cathode follower V3 and a meter 7 is connected between the joint and junction of resistors R3, R4 providing a reference signal. Specification 666,523 is referred to.

Abstract: 828,027. Electric correspondence control gear. BENDIX AVIATION CORPORATION. Sept. 6, 1957 [Oct. 25, 1956], No. 28245/57. Class 40 (1). [Also in Group XXVII] The circuit of an electromagnetically-operated fuel injection system includes a transformer 18 having a primary coil 16 supplied periodically with a voltage variable in response to engine operating conditions to vary the yoke opening periods and a secondary coil 28 which is connected to an amplifier 30, the output of which is connected to the valve solenoids. The transformer also includes a tertiary coil 38 forming a re-setting device. The make-and-break for the primary coil 16 comprises a rotating engine driven earthed arm 22 which successively passes over a series of contacts 20 a . . . h connected to the coil 16, the arm 22 also passing over a second series of contacts 36 a . . . h to complete the circuits of the valve-operating solenoids 34 a . . . h in succession according to the firing order of the engine cylinders. The coil 16 is connected to the power source E through a potentiometer RT which is adjusted in accordance with engine operating conditions such as ambient temperature, pressure and humidity, engine temperature, or induction pipe pressure and the current through coil 16 saturates the core 18 in the positive direction. The resetting coil 38, which is energized by a switch 40 during the periods when the circuit of coil 16 is broken, saturates the coil 18 in the negative direction so that each time the circuit of coil 16 is made by the arm 22, the flux in coil 16 changes from negative to positive saturation, inducing a voltage in coil 28 which is sufficient to render the transistor amplifier 30, normally biased to cut-off, conductive, whereby the injection valve whose solenoid circuit is closed by the arm 22 is operated. The duration of the voltage pulse induced in coil 28, and hence the duration of injection is controlled by variation of the potentiometer RT.
