Title: Mosaic of mos type semiconductor elements
IPC: H01L29/00
Filed: 1971-08-06
Abstract: 1364275 Matrix of photoconductive elements THOMSON CFS 6 Aug 1971 [7 Aug 1970] 37177/71 Heading H1K The photo-MOS elements of a matrix formed on an N type semi-conductor wafer each comprise a diffused P + region 2 (Fig. 4) and associated with and overlapping it a light permeable combination of a thick rimmed metal layer 41- 51 overlying a thin layer of insulation. In operation the junction between the region and body is reverse biased and the metal layer so biased that a depletion layer formed beneath it is continuous with that of the junction so that radiation incident on the layer produces a current across the junction. The row conductors of the matrix consist of metal tracks 52 between the metal layers and cross-talk is avoided by providing a thickened and opaque insulating layer beneath them. In the matrix shown the P+ regions of elements in a column are con nected by metal tracks 25 contacting the regions via apertures 23, 24 in the insulation. In a typical mode of operation the row conductors are connected to bias via an electronic switch so that row selection is effected by the switch and column selection by an optical mask through which the matrix is illuminated.

Abstract: 782,009. Cooling radiators for aircraft. UNITED AIRCRAFT CORPORATION. Dec. 29, 1955 [Dec. 29. 1954], No. 37236/55. Class 64(3) [Also in Group XXXIII] In adapting the spinner of an aircraft propeller for cooling the fluid actuating the variable pitch mechanism, an airstream flows through an open nose piece 56 into a diverging passage 100; this widens into a bell having its centre blocked by a baffle 128 which directs the air into tubes 122 mounted between annular tube plates 124, 126 in a heat exchanger 106 through which the operating fluid circulates from an inlet 118 to an outlet 120. The exchanger s bolted to an annular pedestal 110 itself bolted to the front of the propeller hub. In another form, fins, projecting into the air stream as it passes out of ports 112 in the pedestal are mounted on a circular tubular carrier for the fluid secured to the rear of the pedestal.

Title: Improvements relating to master cylinders of hydraulic braking systems
IPC: B60T11/232
Filed: 1964-09-11
Abstract: 1,083,882. Master cylinders. STOP S.A. Sept. 11, 1964 [Sept. 12, 1963], No. 37251/64. Heading F2F.  A master cylinder comprises a main piston 1, a control piston 2 behind the main piston normally defining a space 15, and a duct 7, 10 formed partly in the control piston and partly in the main piston establishing communication under certain conditions between a replenishment reservoir (not shown) and a pressure chamber formed ahead of the main piston, said control piston carrying a check valve having a free ball valve member 5 which is seated by the dynamic action of the fluid when braking pressure is produced in the pressure chamber. On initial depression of the brake pedal, the control piston moves rightwards until the resilient ring 4 thereon engages the main piston to out off the space 15 from the duct 10. On further control piston movement, the pistons abut and move together, the resultant pressurization of the pressure chamber washing the valve member on to its seat to prevent communication between said chamber and the reservoir via connection 13, axial passages 9 in the piston peripheries and duct portions 7 and 10. On pedal release the pistons are moved back in unison by spring 14. Should suction develope downstream of the valve, ball 5 unseats to re-establish communication with the reservoir. Finally, the main piston flange 12 engages a stop formed by the connection nipple 13 and the pistons separate. The valve seat 6 comprises a resilient ring which deforms when compression exceeds a given value to allow the ball to engage the bevelled end of the duct 7.

IPC: H03K4/502
Filed: 1966-08-19
Abstract: 1,176,171. Transistor pulse and sawtooth Circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 9 Aug., 1967 [19 Aug., 1966], No. 37368/66. Heading H3T. A ramp generator comprises a capacitor C1 connected to a transistor T2 in a capacitancemultiplying manner and charged from a constant current source (such as T1), the capacitor C1 being coupled to a load via a source follower FET. As described, C1 is charged at a rate determined by VR and ST until transistor T3 of a Schmitt trigger becomes conductive, turning off T4 and releasing relay HSA, the normally-closed contacts HSA1 energizing relay B, contacts B1 of which discharge C1 and terminate a ramp function. The discharge of C1 causes T3 to turn off, turning on T4, re-energizing HSA which releases relay B after a time delay. A further ramp function is thus initiated. Diode D1 provides temperature compensation. Contacts B2 provide low frequency output pulses at OP.
