Title: Improvements relating to the lubrication of the gearing and bearings of motor road vehicles
IPC: F16H57/04
Filed: 1920-08-25
Abstract: 170,173. O. D. Cars, Ltd., and Eves, F. S. Aug. 25, 1920. Lubricant conveyed by mechanical means.-The differential gearing of a motor-vehicle is lubricated by oil flung up by the crown-wheel B<1> and caught in a scoop or trough A arranged adjacent to the teeth of the wheel. Oil from the trough is led by a pipe a to a helical coil of wire G surrounding one of the axle shafts D but prevented from rotating, which carries it into the differential housing B, passages being provided to lead it to the various parts. The coil G is surrounded by a sleeve E projecting from the housing B, and may be prevented from rotating by carrying its end e into the orifice a<1> of the pipe a. Oil is also led from the trough A by a passage F to the housing G<1> of the bevel pinion. An intermediate bearing K in the torque tube may be lubricated by causing oil to travel thereto from the housing G<1> by means of a helical coil h fixed to the shaft within a tube h<1>.

Abstract: 532,434. Control of A.C. motors. VICKERS, Inc. Aug. 31, 1939, No. 24948. Convention date, Aug. 31, 1938, [Class 38 (iii)] [Also in Group XXXV] In a transformer in which the secondary surrounds the whole of the flux path provided by the core (i.e in which there is no magnetic shunt) voltage regulation is effected by a saturating winding energized by variable D.C. or variable frequency A.C. The transformer may be applied to speed control of a motor of the type described in Specification 498,586 the windings of which are indicated diagrammatically at A, B, C. The D.C. windings B, C are supplied through a rectifier 30 from the secondary winding 14<1> of the regulating transformer 10<1>. The core of the latter carries also a pair of saturating windings 37, 38 arranged non-inductively with respect to the main windings and included in the circuit of the motor windings B, C in such a manner as to be excited-by A.C. of a frequency dependent on the speed of the motor. Thus variations in motor speed under varying load causes variations in saturating current which regulates the secondary voltage of the transformer in a manner tending to maintain constant speed,

IPC: H03K19/16
Filed: 1958-08-07
Abstract: 895,248. Magnetic storage devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 21, 1959 [Aug. 7, 1958], No. 25353/58. Class 38 (2). [Also in Group XXXIX] A thin anisotropic magnetic film core such as Coo, which may be cylindrical (Fig. 1) or flat (Fig. 3) is set in a neutral remanent magnetization state by a sufficiently large pulse in an adjacent conductor such as row conductor Yo arranged parallel to its direction of easy magnetization to produce a magnetic field at rightangles to that direction. The core is thus prepared for the writing-in of information by a small signal in a column conductor such as Xo of a magnitude insufficient to disturb the state of a similar core such as Co1 in which the remanent magnetization has not been neutralized. The neutralizing and writing pulses may overlap. The matrix arrangement may comprise a single plane film with sets of row and column conductors at the intersections of which information is stored in the film. Read-out by resetting to the neutral state may be by large pulses in the neutralizing conductors such as Yo, large output pulses being obtained. Separate read-out conductors may be provided. Specification 895,247 is referred to.

Skid.-In vehicle brakes of the kind comprising shoes that are lowered parallel to the ground to engage between the wheels and the ground, the shoes for the rear wheels are interconnected at their front and rear ends by transverse bars and are controlled by parallel ropes connected to winding drums. The pair of shoes 1 for the rear wheels are interconnected by transverse bars 6, 8. Ropes 9, 18 attached respectively to the bars 6, 8 are arranged to be wound on drums 11, 21 on shafts 12, 20 geared together by sprocket gearing. The shaft 12 can be rotated to wind in the ropes 9, 18 and raise the shoes to the inoperative position by ratchet gearing including a pawl 13 carried by a hand-lever 27, the shaft being held by a detent 14 on a shaft 15 to which is secured a pedal 16. The movement of the shoes 13 guided by slotted links 28 arranged on each side of the vehicle, each engaging a. pin 30 on the chassis. When the pedal 16 is depressed to disengage the detent 14, the shoes 1 fall on to the track and the wheels 33 run up inclines 36 on the shoes and rest on rollers 32 which permit rotation of the wheels. Rearward movement of the shoes in relation to the vehicle is limited by ropes 4. To permit the wheels to be driven off the shoes by the reversing gear, the rotation of the rollers in the direction corresponding to reverse rotation of the wheels is prevented by the provision of detents (not shown) engaging ratchet wheels on the rollers. To increase the friction of the shoes on the track, the underface of these may be ribbed longitudinally and transversely or chains may be attached to them. Resilient tongues of steel may also be arranged to project from apertures in the shoe surface to ensure proper engagement thereof with the ground and prevent side slip. A brush or squeegee may be mounted on each shoe to clear away mud &c.
