Title: Improvements in or relating to servo-controlled mechanisms for steering mechanism and other power machinery
IPC: B62D5/24
Filed: 1940-02-01
Abstract: 538,413. Fluid-pressure servomotors : hydraulic control mechanism. VICKERS Inc. Feb. 1, 1940, No. 1950, Convention date, Feb. 7, 1939. [Classes 69 (ii) and 135] In the operation of steering and like gear by a power unit 9 which may be a Selsyn unit or a hydraulic follow-up unit such as described in Specification 391, 775, [Group XXXI], mechanism is provided for minimizing the lag which may occur between the signal unit 5 and the output shaft 7, which operates the final controlled member. As shown in Fig. 1, the control member 10 of the power member 9 is driven by differential gearing 12 - 15 from the shaft 6 of the signal member which is also connected by gears 21, 22, 23, to the bevel gear 17 of a second differential gear 16 - 20. The gear 18 of this differential is connected by gears 24, 25, 26 to the output shaft 7, and the ring gears 15, 20 of the two differentials. The arrangement is such that as long as the shaft 7 lags behind the shaft 6 rotation of ring gear 20 takes place in such direction that the control member 16 is accelerated to a greater speed than the shaft 6 so that any lag of the shaft 7 is soon overcome, and the motion is synchronized. The gears 15, 20 then remain stationary. In a modification, Fig. 2, the output shaft 7 is driven by a constant displacement hydraulic motor 27 driven by a variable displacement pump 28 operated by a motor 29 and controlled by a tilting block 30 connected to a piston 32 in a cylinder 33 formed in a housing 34 formed with a cylinder 35 in which a piston 36 operates. Pipes 37, 38 supply the cylinders with hydraulic fluid and operation of the control shaft 6 actuates a gear pump 39 which forces the fluid into the housing 34. A differential gear 49 is arranged between the shaft 6 and bevel gears 45, 46, 47, by means of which a second gear pump 40 is driven. If the shaft 6 is moving faster than the shaft 7 the ring gear of the differential rotates slightly and by means of a shaft 54, lever 55, and rod 56 depresses the piston 36 which causes the piston 32 to rise and operate the arm 30 of the pump 28, 80 as to increase the speed of the motor 27 and shaft 7. In a further modification the piston 32 operates in a single cylinder and is normally controlled by a centring spring, and a third gear pump is substituted for the cylinder 35 and piston 36, and this applies the correction factor to the piston 32. The mechanism also operates upon deceleration to correct the lead of the follow-up mechanism.

Abstract: 411,583. Oil - break switches. DAVIES, D. R., 14, Ruabon Road, Didsbury, near Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 24, 1933, No. 2313. [Class 38 (v).] Magnetic blow-outs.-A liquid-immersed, double-break switch has a coil carrying the main current mounted on a part carrying the movable contacts so as to be adjacent to, and have its magnetic axis disposed transversely of, but coplanar with, the paths of movement of the contacts. Thus a component of force due to the magnetic field of the coil and the field of the arc at each contact acts on the arc substantially at right-angles to the path thereof, so tending to move it bodily away from the switch contacts. In the plan view shown in Fig. 2, the bridge-member comprises insulating members 18, 19 supporting the pivoted, spring-controlled, contacts 6, 7, and an insulating tube 20 on which is wound a helix 21 connected between 6, 7. The magnetic field may be concentrated by means of a magnetic core or magnetic material provided in the bridge-member. Each fixed contact has a depending structure comprising a series of plates of the contour shown in Fig. 2 alternating with plates of the contour shown in Fig. 5 and secured by rods 32. The plates 31 have cut-away parts 40 and those in Fig. 2 are in two parts 33, 34 assembled to form a cut-away part 35 which, with the parts 40, constitute a channel traversed by the movable contact in operating. A circular opening 36 and a flared opening 39 between the parts 33, 34 intercommunicate with one another and with the channel of the movable contact by means of constrictions 37, 38, thus providing in every other plate of each structure a transverse passage along which arc gases pass under the action of the magnetic field, the blast effect being increased by the constrictions. Alternatively, structures as described in Specifications 369,235 and 382,655 may be arranged below the fixed contacts with their blast passages extending in the direction in which the magnetic field tends to move the arc.

Abstract: 953,026. Clicking presses. STAFFORD TOOL & DIE CO. Ltd. Jan. 22, 1963 [Jan. 23, 1962], No. 2362/62. Heading B4B. In a clicking press, mechanism is provided whereby after the work and the tool have been placed in the press and the beam lowered until the work is partly or fully acted on by the tool a switch 13 is tripped which cuts off the power to the beam-operating mechanism and supplies power to a high frequency heat generator 16 acting upon the work whereupon after the desired heating time a further electrical contact is made which causes the beam-operating mechanism to function and return the beam to its uppermost position off the work. A flywheel 1 is connected through a friction clutch 3 to a shaft 4 surrounded by a sleeve 5 having an eccentric in which is mounted a link 6 to which the column 7 of the beam is attached. The sleeve is rotated by an electric motor 8 driving, through reduction gearing 9 and chain drive 10, a chain wheel 11 connected to the sleeve through a roller clutch 12. In circuit with the motor 8 is microswitch 13 adapted to be tripped by a projection 14 on the sleeve and connected to the generator 16. The two parts 17, 18 of a dog clutch are mounted on the sleeve and shaft respectively. When the tool and work are in position and the motor is switched on, the eccentric is revolved to bring the beam into position to contact the tool and the work. The projection 14 then trips the switch 13 to stop the motor and start the generator. On completion of the welding time, a signal is sent from the generator to operate the clutch 3 and turn the shaft 4 so that clutch part 17 engages clutch part 18 thus turning the sleeve to raise the beam off the tool and work.
