Title: Differential carriers
IPC: B60K17/16
Filed: 1972-04-27
Abstract: 1370839 Differential gearing; lubricating CLARK EQUIPMENT CO 27 April 1972 [29 April 1971] 19641/72 Headings F2D and F2A A differential carrier 28 is lubricated by gravity feed at low speeds and by centrifugal feed at high speeds. At high speeds, oil from a stationary trough 54, which is filled by pick-up from the ring gear 24, passes through a passage 58R and an inlet 66R to a cavity 68R. Oil from the cavity 68R passes through a bore 74R, which is of greater diameter than the inlet 66R, and through radial grooves in the disc pack 44 of an anti-spin clutch to lubricate and cool the differential pinions. Similarly, oil from a trough 86, which is fed through an opening 84 in a shroud 82 around the main drive pinion 22, passes through a passage 58L to a cavity 68L. At low speeds, cups 88 formed on the carrier transfer oil from the reservoir 50 to the bores 74 through passages in parts of the housing which protrude into the bores, Figs. 2, 3 (not shown).
Patent GB-1079898-A (GB)
Title: Prewoven bit-wire memory matrix apparatus and methods of fabrication
IPC: G11C7/00
Filed: 1965-05-10
Abstract: 1,079,898. Magnetic data storage apparatus. BUNKER-RAMO CORPORATION. May 10, 1965 [May 8, 1964], No. 19678/65. Heading H3B. In a woven matrix comprising bit-wires 40, Fig. 5, and drive wires 42, magnetic memory portions are formed by a remanent magnetic coating on the bit wire having part-circumferential discontinuities spaced apart along the bit wire to prevent domain interaction from one portion to another. A plurality of drive wires 42 may be connected in series, to form a solenoid around a respective plurality of magnetic portions, these constituting a memory cell. The coating may be deposited by electroplating, electroless plating, vapour deposition or spraying, after the weaving process is complete, and preferably further elements 44 are included in the drive wire direction of the weave, these being of larger diameter than the drive wires and being used to effectively mask a greater part of the bit wires at the edges of each required cell than would be masked by using the drive wires alone. By this means discontinuities 46, Fig. 7 (not shown), are obtained in the magnetic coating, at the boundary of each cell, and if the masking elements have a suitably low softening temperature they may subsequently be removed by melting. The drive wires have a hard insulation so that this is unaffected by heat, and this insulation also serves to avoid the drive wires being coated when electroplating methods are used. The areas masked may be increased by compressing the weave, under a raised temperature, Fig. 14 (not shown), to force the masking element 44 further around the bit wires 40, or by using a double-crimp weave, Fig. 15 (not shown), in which the bit wires 40, as well as the drive and masking elements, follow an undulating path. The areas of the bit wires 40 which are masked by the drive wires 52 may be reduced by the inclusion of spacing elements 41, Fig. 13 (not shown), in the bit wire direction, and by weaving the masking elements 44 from one side of the weave to the other between every adjacent element, while weaving the drive wires 42 from one side to the other only between two adjacent spacer elements 41, so that the drive wires 42 are held off the bit wires 40. As an alternative to depositing the magnetic layer after forming the weave, precoated bit wires may be used, and after the weave has been made using masking elements as above, an etchant resisting coating is applied to the weave, the masking elements removed, and an etchant applied to remove portions of the magnetic coating, as at 65, Fig. 17 (not shown).

Abstract: 298,302. Austin, Sir H. July 26, 1927. Mounting spare wheels and tyres on vehicles.- A carrier adapted normally to support one or more spare wheels or tyres .at the rear of the vehicle in a substantially vertical position, but adapted also to carry them in a horizontal position when luggage is being carried, comprises one or more vertical receptacles with openings at the top, and one or more horizontal receptacles with openings at the rear and intersecting the vertical receptacles. Two brackets C are secured, one to each dumb iron B, and support a U-shaped member D, and upwardly-projecting members E, G riveted to a horizontal member F at each side, the members F being connected by a transverse member H. A member J passes across in front of the wheel W when in the vertical position, and serves also as a guard to protect the vehicle body from luggage when placed upon a grill L, which in the operative position is turned down about pivots M on the members E to the horizontal position shown at L<1>. The horizontal receptacle comprises a U-shaped transverse strip N secured to the dumb irons B, and a central longitudinal strip 0 secured to the member N and to an angle member Q on the chassis. The wheel W is secured in either receptacle by means of two straps a, each of which is attached to the member H or other part and is passed around a spoke. An additional vertical receptacle for a second wheel X is formed by side members R secured to the member H, a transverse member K, and a U-shaped member S connected to the member D by struts T. A member U forms the front of an additional horizontal receptacle. When a single wheel is carried, the members forming the additional receptacles may be detached.

Filed: 1918-12-05
Abstract: 135,944. Thomas, H. J. S. Dec. 5, 1918. Periodic-counter and like speed indicators with recording-apparatus; speed-indicator transmission mechanism.-Apparatus of the periodic-counter type comprises a marking-arm which is yieldingly engaged by a shaft, such as the rotating spindle of a watt-meter, the speed of which is to be determined, and is thereby swung across a record-strip and at predetermined intervals of time is depressed to mark the record-strip and thereupon is returned to its zero position. The arm B carrying the pencil B<2> is frictionally engaged by the disk A and is carried round thereby until an escapement-wheel F driven by a clock-work mechanism releases the pin E<3> of an arm E<1>, which, 'by means of a separate clock, is adapted, through the arm E<2> and adjustable pin E<4>, to complete a circuit through the contacts G, battery G<2>, and electro-magnet D<6>, and thereby cause its armature to be attracted to depress a plate D on to the pencil B<2> to mark the record-strip. Farther movement of the arm E<2> causes the pin E<4> to engage the arm B and thereby carry it back to its zero position. The pin E<4> is adjustable in order that the arm B may be returned accurately to the zero line C<1>. Modified forms of construction are described in which a light spring is provided to maintain contact between the arm R and disk A, or blocks are provided on the arm B with independent springs, or the part B<1> is formed as a magnet and the disk A is made of magnetic material, or a ratchet engagement may be provided.

Abstract: 661,342. Magnetic tests; measuring bridges. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 8, 1949 [Sept. 4, 1948], No. 20621/49. Class 37. [Also in Group XL (b)] A flux-measuring apparatus comprises a search coil 16, Fig. 1, in a closed circuit with a galvanometer 17, the secondary winding 13 of a transformer 12, with or without a resistance 9, both of the latter being in the diagonal of a bridge 1, 2, 3, 4 having at least one arm constituted by a valve 4 whose impedance is varied by the output of a photo-electric cell 6 receiving light from a source 21 via the galvanometer 17. With switch 19 in the lower position, the coil 16 is moved into the field to produce a voltage which deflects the galvanometer 17 to vary the light falling on cell 6 and thus the impedance of valve 4; the out-of-balance current through primary winding 11 produces in the secondary winding 13 a voltage opposing that due to the flux, and when the voltage in the coil 16 due to the flux has been completely cancelled by that from the transformer 12 the meter 10 then reads proportionally to the flux. With switch 19 in its upper position, the system stabilizes itself with the bridge balanced and zero current passing through the meter 10. Range-changing may be effected by changing transformer 12. Spurious voltages produced thermo-electrically may be compensated by injection of equal and opposite voltages from a source 20. In a modification, the bridge, Fig. 2, comprises two valves 25, 26, with a common cathode resistance 24; the galvanometer 43 differentially illuminates two cells 37, 38 to vary the impedance of valve 25; any variation in supply voltage from 29 will affect both valves to an equal extent and have no effect on the reading of meter 31.
