Abstract: 737,399. Electric correspondence control systems. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 9, 1953 [Nov. 7, 1952], No. 28031/52. Class 40 (1). The rotation of a shaft is measured by the corresponding linear displacement of a permanent magnet relative to the core of a transductor to produce corresponding changes in the output current. As shown, the rotation of a shaft 1 produces a corresponding displacement of a magnet 4 parallel to the core 5 of a transductor 6 having a D.C. feed back winding 13, a D.C. bias winding 22 and an A.C. input winding 7 feeding into a magnetic amplifier 10. The output of the amplifier is taken to the control winding of a servomotor 14 which displaces a further permanent magnet 17 parallel to the core of a similar transductor 20 whose output is also fed into the amplifier 10 in opposition, so that the motor 14 comes to rest when magnet 17 has been displaced to the same extent as magnet 14, and the rotation of the shaft of motor 14 is the same as the rotation of shaft 1. The ratio of the rotations may be made other than unity by adjustment of the degree of feedback in winding 13 as by the tappings shown.

Abstract: 242,093. Whitehead Torpedo Co., Ltd., and Jones, A. E. Nov. 24, 1924. Torpedoes, locomotive.-Relates to gyroscopic steering apparatus of the kind carried by a frame mounted on longitudinal trunnions and intended to remain vertical while the torpedo rolls, and consists in the provision of a laterally-swinging pendulum and a servomotor controlled by said pendulum to rotate the gyroscopic apparatus about the trunnions to maintain it in the longitudinal vertical plane. As shown, the gyroscope A, Fig. 1, is carried by a frame C mounted on a fixed trunnion d on a support D at the front end, and provided with a trunnion d<1> at the other end mounted on a support D'. Compressed air is supplied through a passage d<x> in the trunnion d to a number of passages such as c<1> leading through a cut-off valve C<1> to the usual starting nozzles, and through a reducing valve C<3>, Fig. 2, to the usual small nozzles maintaining the spin of the gyroscope during the run of the torpedo. The air from the reducing valve C<3> is also led to a piston-valve C<6> controlled by a cam c<6x> on the vertical spindle of the gyroscope to supply the air to the steering cylinder C', which is arranged in line with the trunnion axis, the piston-rod being connected to the steering rudders through a joint c<8> allowing for the rotation of the gyroscopic apparatus about the axis of the trunnions relatively to the torpedo. The pendulum E is hung from a pivot e on the frame C, and has an upward extension e<1> connected to a piston-valve F<1>, Fig. 3, axially disposed in a piston E<2>, which is attached to the frame C and is movable within a floating cylinder E<3> provided with rack teeth e<3> in mesh with a pinion d<3> on the fixed trunnion d. This constitutes a servomotor supplied with compressed air from the reducing valve C<3> under the control of the pendulum for making the frame C follow the movements of the pendulum relatively to the torpedo; that is, for maintaining the frame in the vertical position. The servomotor may in addition be made to effect relative movements between the horizontal rudders to check the rocking movements of the torpedo. The swing of the frame C relatively to the torpedo is damped by an air dashpot.

Abstract: 1,156,661. Railway stops. COAL INDUSTRY (PATENTS) Ltd. 4 Oct., 1966 [6 July, 1965], No. 28601/65. Heading B7L. [Also in Division F2] A retarder for a rail vehicle, particularly for slowing and arresting mine cars travelling too fast down a steep incline, comprises an I-section girder 14 disposed between the track rails and slidable along the floor of a fixed channel 15. Angle irons 16 secured to the sides of the channel 15 engage the upper faces of the lower flanges of the girder 14, to provide a fixed frictional resistance, and also carry friction strips 29 engageable by levers 27 which in turn are engaged by counterweighted cam portions (18b, Fig. 2, not shown) of a pair of pivoted hooks 18 carried by a box frame 17 secured to the girder 14. The hooks 18 are normally retained in the withdrawn position shown in Fig. 1 by a catch bar (31, Fig. 2, not shown) on a longitudinally slidable rod (34, Fig. 3, not shown), the end of which is engageable by a counterweighted trip lever (37) (shown to the left of hook 18 on Fig. 1), the arrangement being such that the trip lever is deflected by every car, but insufficiently to enable it to release the catch unless the car is travelling faster than a predetermined speed. In this event, the hooks 18 are released and, with the assistance of a leaf-spring (38, Fig. 2) are quickly erected into vertical position for engagement with one of the car axles. Upon such engagement, the levers 27 are urged against the friction strips 29 with a force proportional to the momentum of the car so that the car is, in most cases, smoothly brought to rest. If the speed of the car is exceptionally high, however, the car is abruptly brought to a standstill by the jack-knifing of a pair of girders 13, 10 to which it is connected, which causes these girders to assume the positions 13<SP>1</SP>, 10<SP>1</SP> in which abutments on them mutually engage, thus forming a rigid buffer.
