Abstract: 1,057,082. Controlling aircraft. SPERRY RAND CORPORATION. Oct. 14, 1963 [Oct. 12. 1962], No. 40369/63. Heading B7G. [Also in Division G3] An aircraft control surface 10, e.g. an elevator, is operated by a servomotor 13 having inputs (a) from a reference attitude 26 through synchros 27, 29; (b) from a knob 39, by which the desired attitude of the aircraft relative to the reference is set, acting through synchros 40, 41, 42, the signal from the rotor of synchro 42 being fed to a follow-up servo 43 to nullify the signal from the synchro 42 and rotate the rotor of synchro 29; (c) from a synchro 22 connected to the control surface and providing a feedback signal; (d) representative of a manual force applied to a controller 32, from line 38, through an integrator 46 driving the rotor of the synchro 41, then through the synchro 42 and followup servo 43 as in (b). This last input is derived from two synchros 36 and 22, the rotors of which are connected respectively to the controlled 32 and control surface 10. The controller and control surface are also connected by a stretching cable 33 so that their relative displacements and hence the relative angular positions of the rotors of the synchros 36, 22 are dependent on the force applied to the controller. The system is initially synchronized by selecting " SYN " on switch 71, whereby a clutch 16 is disengaged and relays 63, 67 and 85 are de-energized. switching the servo 43 from the rotor of synchro 42 to the rotor of synchro 29, thereby nullifying any signal from the latter.

Title: Improvements in or relating to circuit arrangements for the key selected transmission of alternating current signals
IPC: H04M1/50
Filed: 1964-10-06
Abstract: 1,078,279. V.F. signalling number sender. TELEFONBAU UND NORMALZEIT. G.m.b.H. Oct. 6, 1964 [Oct. 26, 1963], No. 40616/64. Heading H4K. A voice frequency signalling key sender for signalling in an n out of m frequency code uses not more than n +1 frequency generators and is arranged so that if two adjacent keys are actuated at once at least n + 1 frequencies are transmitted. When this number of frequencies is received a circuit prevents evaluation of the signal. In one form (Fig. 2, not shown), using a different frequency for each key, two transistor oscillators produce signals on depression of even and odd keys respectively, the frequency being determined by a capacitor selected by the particular key. The keys are in numerical sequence, so that depression of two produces an "odd" and an "even" frequency. Another embodiment (Figs. 3 and 4, not shown) uses a 2 out of 5 code and each key causes the transmission of two frequencies from separate oscillators. There are three oscillators in all and each is capable of transmitting three from a total of five frequencies. The arrangement of keys (in two rows of five, for example) and the allocation of frequencies between them are such that the depression of any two adjacent keys causes the transmission of three or four frequencies.

Title: Multiple member windings for electrical rotating machines
IPC: H02K23/54
Filed: 1966-09-14
Abstract: 1,109,529. Windings for dynamo-electric machines. SOCIETE D'ELECTRONIQUE ET D'AUTOMATISME. 14 Sept., 1966 [16 Sept., 1965; 19 July, 1966], No. 41012/66. Heading H2A. The rotating commutated printed winding of a planar-air-gap machine is distributed on both sides of several planar carriers which may be lumped together in a single air-gap or else distributed in several spaced air-gaps. The individual winding carriers are so wound that, no matter how many such carriers are stacked together, the winding on each carrier is the same. This is done by using windings of series-wave pattern in which there is an odd number of conductors in each layer, and a certain number of conductors at one (the inner) edge are left unconnected to each other but are connected to windings on other discs. These unconnected conductor ends are connected to unconnected conductors on adjacent winding carriers displaced by an amount equal to the winding progression, and in the end layers appropriate connections are also made without shift. As shown for an eight-pole winding of 49 half-turn conductors, 7 inner conductors, 38, 40, 42, 44, 46, 48, 1, are left unconnected but are interconnected with the conductors of the other carriers. The seven interruptions in the winding on each carrier, are spaced by 2 conductors, this being the spacing arrived at:after the winding wave has passed twice round the armature. These unconnected conductors are, instead, connected at 200, 300 to conductors displaced by two in the adjacent carrier I, II or III. The unconnected outer conductors of the outer carriers are interconnected without transposition by leads 400. The remaining outer. end conductors are interconnected by lead 500 The individual carrier discs may be interconnected by flexible leads and clamped between spacers and insulating washers (Fig. 3, not shown). Commutator connections are taken from the front of the first disc and the rear of the back disc, interconnections being made on the commutator so that only four brushes are needed. The discs work between locally magnetized forrite rings producing an axial eightpole flux. Instead of using several gaps, the discs may be moulded into a single resin, block (Fig. 5, not shown) and work in a single air-gap, and the brushes bear directly on one end member to obviate the separate commutator. In a further modification, the connections are attached to obliquely disposed metal inserts in insulating rings attached to the inner edge of each side of each winding disc. The inclination of the inserts is mutually reversed on the two faces of each disc, and this serves to bring the connection points into registration (Figs. 6 and 7, not shown).

Abstract: 1,106,681. Two for one twisters. JAMES MACKIE & SONS Ltd. 14 Oct., 1964 [17 Oct., 1963], No. 41111/63. Heading DID. In a two for one twisting device wherein the carrier bracket 64 within the balloon is maintained stationary by magnetic means, the magnet 70 and/or the co-operating member 68 is mounted to be capable of limited movement relative to its support and means are provided to absorb energy during such movement; thus oscillations of the bracket 64 are damped. As shown the member 68 is a second U-shaped magnet mounted on the bracket 64 and magnet 70 is pivotally mounted on a fixed bracket 72 by a pin 74. Tubular rubber buffers 76 are arranged between the magnet 70 and a fixed plate 78 so that pivotal movements of magnets. 70 caused by movements of magnet 68 result in distortion of the buffers and absorbtion of energy. In place of tubes 76 springs or dash pots may be used. In a further form magnet 70 is mounted on a single leaf spring comprising laminations of steel and rubber or a plastics material. Alternatively the magnet is mounted on a flat first pin so that energy is absorbed in friction. An electromagnet may be used. The shaft (22), Fig. 1 not shown, of the flyer (8) is driven via a belt (28) and gear (32). The haul pulleys (14) are driven via a belt (30), associated gears (34, 36), planet wheels (40, 42) on a shaft (44) rotatable in flyer (8), associated gears (38, 50) and a gear (54) on a shaft (52) taking drive from the gear (50). The arrangement of planet gears (40, 42) drivingly connected to gears (36, 38) by toothed belts, ensures that the transmission of drive to the' haul pulleys is unaffected by the speed of rotation of the flyer: thus the speeds of the flyer and haul pulleys can be independently adjusted The shaft (52) also carries a gear (56) which engages a gear (58) to drive the traversing scroll (20). A chain drive (62) causes the package spindle (2) to be driven from the scroll shaft, a slipping clutch being incorporated in the drive path so that the tension in the yarn being wound can be adjusted by adjusting the pressure in the slipping clutch.
