Title: Improvements in or relating to electrical position indicators
Inventor: ROBINSON ANTHONY GEORGE
IPC: C09B29/15
Filed: 1964-10-01
Abstract: 1,089,242. Correspondence control systems. WESTLAND AIRCRAFT Ltd. Sept. 27, 1965 [Oct. 1, 1964], No.39911/64. Heading G1N. A correspondence control system, e.g. for a hovercraft steering gear, comprises a pick-off device including first and second relatively movable parts, one part being angularly displaceable relative to the other about a pivotal axis, an elongated coil assembly 5 (Fig. 5) on one part and a detector coil 11 on the other part, the coil assembly comprises two compound coil windings on a core in end to end relationship and curved Fig. 3 (not shown), the radius of the curve being equal to the distance between the pivotal axis and the detector. The coils are connected in phase opposition and have a greater density of turns at their ends away from their junction as illustrated in Fig. 3 (not shown) so that when energized with A. C. there is a non-uniform flux density along the core and a voltage will be induced in the detector coil of a magnitude and phase dependent upon its position on a path parallel to and at a constant distance from the longitudinal axis of the coil assembly. This voltage will increase from a null value, when the detector coincides with the junction of the coils, to a maximum value at each end of the core. A ferrite slug 12 may be inserted at each end of the core for trimming purposes and to increase the induced voltage when the detector coincides with the core ends. On a hovercraft either the detector part or the coil assembly may be fixed to the hull while the other part is fixed to a propeller pylon (3) Figs. 1, 2 (not shown). In operation an armature of a steering wheel demand pick-off 14 (Fig. 4) is mechanically connected to a steering wheel, movement of which produces an output demand signal which is fed to an amplifier 15. The amplified signal is fed to an electromagnetic valve which initiates movement of hydraulic rams causing pylon 3 to move carrying the detector coil with it, and the detector coil output is fed to the amplifier in such a sense as to cancel the demand signal from the steering pick-off.

Abstract: 1,082,103. Cathode - ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 20, 1965 [Oct. 1, 1964], No. 39959/65. Heading H4T. Digital signals indicative of the orthogonal components of a vector (e.g. forming portion of an Alpha-Numeric character) are converted to analogue voltages and utilized for direct control of the current in the X and Y deflection coils of a cathode-ray tube on which the vector is to be traced. Considering the X deflection only (a similar arrangement being employed in respect of the Y deflection) the digital signals comprising six bit words derived from an assembly register are fed to separate AND stages 21 . . . 26 of a buffer register and via inverting stages 31 . . . 36 to AND stages 41 . . . 46 the outputs of both sets of stages when read by a positive pulse on transfer line 47, being fed to respective stages 51 . . . 56 of a latch register which operates to produce a positive output from stages 61 . . . 66 and a negative output from stages 71 . . . 76 in the binary-one condition whilst reversing these polarities in the binary-zero condition. The former stages are connected to weighted resistors 101 forming a digital-to-analogue converter and the latter to a similar converter 103, both converters being arranged to control the flow of current through respective halves 113, 113<SP>1</SP> of a centre-tapped deflection winding (critically damped so that a reasonably linear deflection is produced) the arrangement operating such that current flow through the converters 101, 103 occurs only when the output of the associated latch register stage has a negative value. Each vector component is traced in a fixed time irrespective of its length and to prevent variation in trace brightness a control signal proportional to the current change is derived from resistors 107, 107<SP>1</SP> and after suitable shaping, employed to control the tube beam intensity.

Abstract: 1475958 Motor vehicle transmission gearing FORD MOTOR CO Ltd 17 Oct 1975 [9 Dec 1974] 42652/75 Heading B7H [Also in Division F2] An automotive transmission providing three forward ratios and reverse employs a hydrodynamic torque converter driving planetary gearing with first and second trains, and a clutch for connecting the input member of the converter to the sun of the second train to by-pass the converter when high ratio is established. The planet carrier 144 of the second train constitutes the output member of the gearing and, in the embodiment described, is integral with the carrier 146 of a differential gear 20 of which one side wheel 148 is connected to an output shaft 168 through a universal joint 166 and the other side wheel 150 to an output shaft 112 passing through the gearing, torque converter, and engine shaft 30. The arrangement is suitable for an engine/transmission unit mounted transversely in a vehicle. The various transmission ratios are established by a brake 50, 52 and clutches 108, 120, 190 actuated by fluid pressure responsive, annular pistons 54, 92, 128, 184, and by a band brake 180. Application of the brake 50, 52 to immobilize the carrier 38 of intermeshed planets 70, 72 of the first train establishes low ratio, in which the sun 74, driven by the torque converter turbine 24, drives the ring gear 66 through the planets, and the ring gear 68 of the second train, directly coupled with the ring gear 66, causes the carrier 144 to be driven since the sun 104 is held by a one-way clutch connection 100 with the carrier 38. Engagement of the clutch 190 locks up the second train to establish intermediate ratio, and release of the brake 50, 52 and the clutch 190 and engagement of the clutch 120 and brake 180 establishes high ratio in which the sun 104 is driven directly by the engine shaft 30, bypassing the torque converter, and the ring gear 68 is held by the brake 180. For reverse ratio the ring gears are held by the brake 180 and the sun 104 is coupled to the carrier 38 by the clutch 108. A gear 196 carried by the universal joint 166 drives a speedometer gear 202 and a governor 198 for providing a speed pressure signal for automatic control of the clutches and brakes.
