Title: Improvements relating to selecting devices for automatic and semiautomatic telephone systems and circuits therefor
IPC: H01H67/16
Filed: 1921-11-24
Abstract: 189,984. Siemens Bros & Co., Ltd., and Humphries, H. E. Nov. 24, 1921. Automatic exchange systems; selectors. - A selector on reaching an end position in its rotary motion is released as regards that motion, so that it may search over the same level of contacts more than once, cr over more than one level. In a Stronger selector having separate release detents, a roller 18 on a pivoted member 16 normally engages in a recess 14 in a cam 13 loose on the wiper spindle 2. On reaching the last contacts in a level, a pin 10 on a plate 9 on the spindle strikes the cam 13 and forces the roller 18 into a second recess 15, causing the release detent 6 to disengage from the rotary ratchet 3 by contact between its tail 26 and the tail piece 20 of the member 16. On return of the spindle a pin 11 on the plate 9 strikes the cam to bring the roller 18 into the first recess 14. In operation, the circuit of the lifting magnet H is intermittently closed upon the energization of the impulse relay A. a relay F being energized in series with a slow-release relay E, which is shortcircuited at each impulse. but does not release its armatures until the completion of impulse sending, when it provides an alternative circuit for the relay F, and connects up the rotary magnet D. On reaching the last bank contact of the level, a circuit is closed through the test relay C, test arm 15, bank contact 16, a relay Q and the vertical magnet H, which does not operate on account of the high resistance of the relay Q, which cuts out the rotary magnet D at the contact q<2>. On the automatic return of the wipers to the initial position, the relay Q is short-circuited by contact w<1>, and the vertical magnet raises the wipers one step. The release of the relay Q then cuts out the vertical magnet H at the contact q<1> and brings the rotary magnet D into operation at the contact q<2>. If repeated searching over the same level is required, the relay Q is net connected to the vertical magnet, but through a resistance to battery.

Title: A Device for Stabilising a Space Vehicle
IPC: G01S3/786
Filed: 1966-11-22
Abstract: 1,169,204. Automatic attitude control. GENERAL ELECTRIC CO. Nov. 22, 1966 [Nov.22, 1965], No. 31984/66. Heading G3R. In a system for stabilizing the attitude of a vehicle in space, deviations about orthogonal axes relative to a source of radiant energy are detected and automatically corrected by controlling the storage of angular momentum which is unloaded by torque-producing means interacting with an ambient magnetic or electric field. As shown, an earth satellite is in a desired position about one axis relative to the sun 62 when solar batteries 16, 20 adjacent to screens 18, 22 on it are equally illuminated and their currents are equal and oppossite. Any deviation from this condition produces current through a reversible electro-dynamic pump 14 which circulates mercury through a conduit 12 to correct the deviation by the momentum reaction on the satellite. In a similar manner the attitude of the satellite about a perpendicular axis is maintained by solar batteries 38, 42 controlling another fluid flywheel 34. In order to reduce the duty on the flywheels, deviation about the first axis also controls the energization of a solenoid 31 which slowly corrects the attitude by interaction with the earth's magnetic field, a permanent magnet 54, pivoted as shown and having limited movement, being provided to rotate the control system until it is in such a position that solenoid 31 is properly effective. Interaction with an electric field instead of a magnetic field is referred to.

Title: Improvements in or relating to motor road vehicles
IPC: B60G5/053
Filed: 1931-11-18
Abstract: 388,496. Road-vehicle undercarriages. THORNYCROFT & CO., Ltd., J. I., Smith Square, London, and BARFORD, V. G., Motor Vehicle & Engine Works, Basingstoke, Hampshire. Nov. 18, 1931, No. 31985. [Class 108 (ii).] Relates to rigid six-wheel motor vehicles of the kind having a pair of rear axles associated on each side with a pair of longitudinally arranged laminated springs 11, 11a which are pivoted at intermediate points 10, 10a to the vehicle frame, e.g. by brackets 12a, while the forward and rear ends of the springs are flexibly connected to the corresponding axle or axle casing by a rigid plate or frame 2 mounted on the axle or axle casing through the medium of longitudinally disposed trunnions 1, 1a. In order to prevent the side thrust that is transmitted between the axles and frame when the vehicle is cornering or travelling over uneven ground from straining and unduly wearing the trunnion pins associated with the springs 11, 11a, an axle controlling or centralizing device independent of the frames 2 is disposed transversely between the axles and positively connects the vehicle frame with the axles or axle casings. As shown, the centralizing device comprises a pair of V-shaped links 6, which may be in the form of spring blades, pivotally mounted at their centres on a longitudinal pin 8 revolubly supported by arms 13 on a fixed transverse member 9 carried by the brackets 12a. At their outer ends the links or blades 6 are provided with eyes 6a which embrace transversely disposed pins 5 carried by the forked inner ends 1 of the trunnions that support the frames 2. In this way the links 6 prevent lateral displacement of the axles relative to the vehicle frame, but, owing to freedom of movement afforded by the joint 8, 9, 13 permit free flexure of the springs 11, 11a, arising from varying load or unevenness of the ground surface. Specifications 259,322, [Class 108 (ii), Road vehicles, Undercarriage details &c. for], and 357,251 are referred to.

In order to keep the charging- voltage for the condenser C2 substantially constant, without using an independent source, the charging-resistance R2 may be connected to the positive pole 4 by a resistance R1 and by a condenser C1 to the cathode of the amplifier V. In a modification, Fig. 2 (not shown), the lower plate of the condenser C1 is connected to the cathode by a condenser and to the negative pole 5 by a resistance.
