Title: Improvements relating to the automatic steering of dirigible vehicles
IPC: G05D1/02
Filed: 1927-04-04
Abstract: 268,833. Sperry Gyroscope Co., (Assignees of Sperry, E. A.). April 3, 1926, [Convention date]. Steering-gear. - In an automatic steering system for ships, aircraft, torpedoes and other dirigible craft the steering gear is controlled by a member responsive to E.M.F. variations. upon changes of course, in a device, such as an earth inductor compass, sensitive to the earths magnetic field. In one form the control member is a galvanometer which acts selectively on thermionic valves, on light-sensitive units, or on solenoids which in turn act through a pneumatic relay and transmission system. The armature 1 Fig. 4 of an earth inductor compass is mounted in gimbals on a base 12 which is adjustable by worm gearing 13, 14, the brushes 8, 9 on the ring 2 being coupled to contacts 22, 23 that engage fixed rings 24, 25, secured to the deck 11 of the ship. Rotation of the armature is effected by compressed air from a nozzle 9<1> impinging on a bracket wheel 8<1>. For setting a new course the worm 13 is rotated by hand or by a servo-motor 17, Fig. 1, adapted to be removably controlled by wireless, light rays or other radiant energy device. The rings 24, 25 are coupled to the controller 26 which is a sensitive galvanometer, the needle 27 carrying contacts 28, 29 engaging sectors 30, 31 which are concentrically pivoted at 36 and are coupled by levers 40, 41 to the rudder head to constitute a follow-up device. The sectors 30, 31 are connected to solenoids 47, 48 which act on pistons 50, 50' of an air pressure system to move the control valve 68 of motor cylinders 72, 73, the pistons 72<1>, 73<1> of which actuate the rudder 45. The air pressure supply takes the form of a compressor 65 and storage chamber 64. In order to reduce friction and take load off the galvanometer the sectors are carried bv a block which is reciprocated toward and away from the contacts. In a modification the galvanometer needle carries a mirror upon which a beam of light is incident, the source of light being carried by the block which is linked by follow-up gear with the rudder movement of the needle and mirror directs the reflected light on to one of two thermionic or light sensitive valves whereby the resistance to an electric current is varied and the resultant unbalance is magnified by a " wireless " amplifying circuit to cause the solenoids 47, 48 to function and set in motion the rudder-actuating gear. Specification 227,489, [Class 40 (i), Electric signalling systems &c.], is referred to.

Filed: 1949-04-06
Abstract: 658,564. Rectifying. BRITISH THOMSONHOUSTON CO., Ltd. April 6, 1949, No. 9395. Convention date, April 19, 1948. [Class 38 (ii)] [Also in Group XXXIX] Relates to a magnetic amplifier designed for operation with an inductive load. In Fig. 1 and according to the invention a rectifier 12 is connected in parallel with the inductive load 15; the circuit is otherwise of known regenerative form comprising reactors 8, 9 in series respectively with rectifiers 10, 11 with the load 15 connected between the junction of rectifiers 10, 11 and the mid-point of an auto-transformer 2 whereby the voltage directed towards reactor 8 is 180 degrees out of phase with the voltage directed towards reactor 9 and a unidirectional current flows in load 15. As fully explained in the Specification with the aid of voltage waveforms, Figs. 3 to 6 (not shown), and comparison with prior art, Fig. 2 (not shown), the rectifier 12 produces circuit performance with an inductive load analogous to circuit performance with a resistive load; more particularly rectifier 12 functions to produce interruptions in the current flow through inductive load 15 twice during each cycle and thus interruptions in the saturable magnetic flux in magnetic element 7 so that during these interruptions the relatively weak current flowing through signal winding 16 regains control and is effective in controlling the degree of saturation of element 7.

Abstract: 1364771 Displacement transducers; measuring material inductance HONEYWELL Ltd 4 June 1973 [2 March 1972] 9736/72 Headings G1N and G1U The relationship between the output of a differential transformer and the displacement of its core is linearized by controlling the amplitude of the voltage energizing the primary winding in accordance with the signal from the secondary windings. The transducer (Fig. 1) consists of a rod 8 linking two capsules 6, 7, subjected to individual pressures via inputs 2, 3, and carrying an iron core 10 which varies the coupling between the windings of transformer 9 in accordance with the pressure difference. The signals from the two secondary windings 27, 28 (Fig. 2) are rectified at 37, 38 to produce D.C. voltages V 1 , V 2  across capacitors 39, 40. The difference V 2  -V 1  is amplified at 35 to control the current taken by transistor 36 and to develop a corresponding output voltage across load resistor 23. The output voltage corresponding to V 2 -V 1  is fed back to adjustable amplifier 30, whose output controls a further amplifier 31 in opposition to signal voltage V 1 . The signal from amplifier 31 controls the level of oscillation of oscillator 25 feeding the primary winding 24 of  the transducer. Adjustment of the slider of a potentiometer 50 in amplifier 30 from its mid position compensates for concave or convex deviation of the output/displacement relationship from linearity.
