Abstract: 1377783 Photo-electric detector system G D SEARLE & CO 1 Feb 1972 [1 Feb 1971] 4657/72 Heading G1A [Also in Divisions G2 and H4] A radiation detector uses a light guide 45 between a scintillating crystal 37 and the lightsensitive surfaces 26 of a plurality of photomultipliers, e.g. P8-P12, the surfaces of the light guide 45 which are not transmitting light to the photo-multipliers surfaces 26 via an optical coupling compound or receiving light from the scintillating crystal 37 via an optical coupling compound being made light absorbent as at 17. This is said to reduce "hot spots". Triangular cross-section indentations 15 in the surface of the light guide are provided between adjacent photo-multipliers. The outputs from the photomultipliers are matrixed to produce x, y and z signals, the signals being fed to an oscilloscope only when the z signal indicates radiation within a selected energy window. The oscilloscope output may be photographed, or the signals may alternatively be fed to a digital computer.

Filed: 1941-04-16
Abstract: 547,534. Hydraulic couplings. WINDER, A. S. April 16, 1941, No. 4956. [Class 69 (ii)] To boost the power transmitted by a gear train such as that employed between the steering- wheel of a car and the road wheels, or by a long train of gears in a calculating machine, a gear wheel 2 driven by a power shaft 1 transmits power to the gear train through a hydraulic transmission device comprising a pump casing 8, Fig. 2, filled with oil ducts secured to a sleeve 9 on the gear 2. A series of gear wheels 6, 61, 62 are mounted in the casing and form gear pumps with a central gear 4 mounted on the power shaft 1. The power transmitted by the gear 2 is controlled by a rotary valve 12 concentric to the shaft 1 and operated by a control gear 3 which is driven by the gear train. The valve plate has apertures 17, 171 which may register with the gear pump outlets and inlets 15, 16, when no power is to be transmitted by the gear 2; the maximum power is transmitted when the passages 15, 16 are completely closed. Normally the gear 3 automatically adjusts the valve to supply the power required by a follow-up action. The casing 8 is enclosed in a rotary cover 18 which may be filled completely with oil, and oil seals 22, 23, 24 are provided to keep the gear mountings leak proof. The level of the oil need only be sufficient to cover the valve plate 12. Leakage into the pockets 10, 11 of the pump plates may be prevented by cover plates 26. In a modification the valve 12 is replaced by a ported disc, or sleeve mounted concentrically at the side of the pump casing and pressed towards the casing by a thrust ball bearing. A number of such control devices may be arranged side by side on a common power shaft.

Title: Improvements in gyro verticals
IPC: G01C19/44
Filed: 1942-04-16
Abstract: 619,939. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. April 16, 1942, No. 5088. Convention date, April 16, 1941. [Class 97 (iii)] In a gravity responsive gyro-vertical or artificial horizon, the axis of the rotor in its normal operating position is forwardly inclined with its top end foremost in the direction of movement of the craft. The angle of inclination is preselected so that at a prescribed rate of turn of the craft no error is indicated due to centrifugal action upon the pendulous erecting devices.. As shown, the instrument is in its normal operating position, the spin axis of the rotor within its casing 1 being inclined in a forward direction. The casing is mounted for oscillation about an horizontal athwartship axis within a gimbal ring 2 pivotally mounted in a fore and aft axis within the casing 3. A lever 4 carrying an horizontal indicating bar 5 is pivoted on the gimbal ring 2 and is actuated by a pin 9 extending from the gyro case 1, the arrangement being such that the bar 5 indicates the horizontal when the rotor axis is in its normally inclined position. Pendulous shutters 14 co-operating with air vents 13 maintain the position of the gyro, the athwartship shutters being loaded with weights 27 for this purpose. When a uniform turn is made at a rate appropriate to the inclination of the spin axis, the errors of indication which occur with an upright spin axis due to the centrifugal forces acting on the erecting pendulums, are eliminated, the spin axis of the gyro being caused to describe a cone at a rate substantially equal to the rate of turn of the craft. In a modified construction, the erector casing 15 is arranged vertically, the gyro case 1 being arranged at an angle thereto. The Specification as open to inspection under Sect. 91 comprises also an electrically-driven gyro-vertical erected by a rotating magnetic field produced by the windings of a stator ring universally supported from the outer gimbal ring which co-operates with a part-spherical conductor mounted eccentrically on an extension of the rotor casing. A rheostat is provided for varying the rate of erection of the spin axis in accordance with different rates of turn.

Abstract: 1531871 Stabilizing optical apparatus WESTINGHOUSE ELECTRIC CORP 11 Feb 1976 [25 Feb 1975] 05248/76 Heading G2J A stabilized optical system comprises a support 20 on which a gimbel is mounted for rotation about a first (elevation) axis. An inertially stabilized platform is mounted for rotation relative to the gimbel about a second (azimuth) axis orthogonal to and coplaner with the first (elevation) axis. Stabilization is e.g. by means of elevation and azimuth gyros 15, 16. A mirror 10 is mounted on the stabilized body for rotation relative to the body about a third axis which is concentric with the second axis. A belt and pulley drive system ensures that the mirror rotates through half the angle of relative rotation between stabilized body and gimbel. Operation. The stabilized body is set up to point its axis along a direction LOS to be sighted. Light entering along the line is reflected via mirrors 10, 11 and lens 12 to detector 15. If the mount 20 moves, the stabilized body will remain pointing along LOS and the half angle movement of mirror 10 maintains the light path centered on the mirror 11 and hence on the detector.
