Title: Improvements in or relating to change speed gearing
IPC: F16H3/34
Filed: 1948-10-22
Abstract: 656,689. Change-speed gearing. VICTORIA MACHINE TOOL CO., Ltd., FRYE, J., and SELBY, J. Oct. 22, 1948, No. 27523. [Class 80(ii)] Relates to toothed or friction changespeed gearing in which unitary countershaft wheel clusters 5a, 5b, 8a, 8b &c. Fig. 1, are mounted on a carrier 9 turnable to bring one or other of the wheels 5b, 8b... into driving engagement with a driven (or driving) wheel 1, the wheels 5a, 8a... being in constant driving engagement with a driving (or driven) wheel 2. The invention consists in means for turning the carrier 9 comprising a hand-actuated rotary element 15, Fig. 5, coupled to the carrier by a step-down gear transmission such as a worm 13 and worm wheel 12. As shown, adapted as a toothed gearing for incorporation in the knee assembly of a knee-type milling machine, wherein the driven gear 1 drives the feed table, and in order to double the speed ratios available, the driving gear 2 is itself driven from a shaft 11, powered by the feed motor, at either of two speed ratios according to whether a gear 17, slidably splined on the shaft 11, is brought into direct clutching engagement with the gear 2 through dogs 16 or into mesh with a layshaft train 18, 19, 20. The main gear has six progressively graded countershaft gear clusters, angularly spaced at 60 degrees, and, to prevent fouling between adjacent gears, certain of them may be partly cut away e.g. the gears 5b, 8a. The transmission 13, 12 has a six to one step-down ratio, so that the element 15 is turnable through a complete revolution to change gear by one step. A pin 29 urged by a spring 33 engages the notched edge of a fixed casing 30 to locate the disc 15 in ratio-engaging position, the pin being released to turn the disc by depressing a slider 31. An indexing device 24 viewed through a fixed window 35 is rotated from the disc 15 through six to one step-down ratio gearing 28, 27, 26, 25 so as to move 60 degrees for each ratio change. Either or both of the gears 1, 2 may be internally instead of externally, toothed. According to the Provisional Specification, the shaft 11 is driven from the machine feed motion through planetary reduction gearing, and the gear 2 may be fast with the shaft.

Abstract: 742,708. Transmitting mechanical power. BRITISH THOMSON-.HOUSTON CO., Ltd. Nov. 4, 1953 [Nov. 4, 1952], No. 27731/52. Class 38 (4). A transmission system electromagnetic coupling 1, Fig. 1, comprises a driving member 2, a driven member 3, and two exciters 4, 6 drivable by the respective members and so electrically connected to each other and to the coupling excitation winding that when the members are rotating in the same direction as each other the voltage applied to the winding is the difference between the voltage of the two exciters. The invention is applicable to a reversible transmission system such as for ship propulsion as disclosed in Specification 717,189, by providing that both couplings therein may each have two respective exciters or both couplings may share a single pair of exciters, and for the latter arrangement, Fig. 2 of the present Specification, shows a reversing change-over switch 9 by which the exciters 4, 6 may be selectively interconnected with each other and with the forward and reverse coupling excitation windings 10, 11. When initially the drive is reversed in either direction the propeller causes the driven member of the coupling to rotate in the opposite direction from the driving member and under these conditions the exciters voltages are additive to provide a boost in the excitation of the coupling. The exciter 4 on the driving side will generally be of larger capacity than that of exciter 6 on the driven side.

Abstract: 849,654. Preventing corrosion. METALLGESELLSCHAFT A. G. Sept. 5, 1957 [Oct. 1, 1956], No. 28096/57. Class 123(1) In a process for the cathodic protection against corrosion of a metallic surface immersed in an electrolyte, for example, sea water, an adherent lime coating is first formed on the surface by subjecting it to a high polarising current of density 1,000 to 2,000 m A per square metre produced by sacrificial anodes of magnesium or by an external source and the coated surface is then protected over a long period by zinc anodes arranged to give a low current density of from 30 to 70 m A per square metre. To ensure that the zinc anodes, which are installed before the polarizing process, operate at their normal potential thereafter, the polarising current density is adjusted so that the potential of the zinc anodes does not fall below -1,400 m V measured with respect to a standard calomel electrode.

Abstract: 963,027. Controlling motor vehicles. ELECTRO-HYDRAULICS Ltd. July 20, 1962 [Aug. 2, 1961], No. 28131/61. Heading B7H. [Also in Division F2] An industrial truck with separate hydraulically operable clutches for forward and reverse gears and hydraulic brakes is provided with a master cylinder 26 or other hydraulic pumping device which supplies pressure fluid to control valve means for the clutches, the pumping device being so arranged as to be operable simultaneously with the brakes if desired. In Fig. 1, a selector valve 3 either supplies fluid from pump 1 and pressure control valve 2 to either forward gear clutch control cylinder 7 or reverse gear clutch control cylinder 10 through corresponding valve 12 or 16 or connects both of cylinders 7 and 10, which may control the annulus gears of epicyclic gear trains, to a reservoir. When pedal 30 is depressed, fluid from master cylinder 26 displaces the pistons 14, 18 of valve operators 12, 17 upwards against the bias of springs 15, 19 changing the connections of valves 12, 16 from 12a and 16a to 12b and 16b and thus connecting both cylinders 7, 10 to reservoir and disengaging the clutches. Partial depression of pedal 30 restricts fluid flow to or from the cylinders 7, 10, for inching movements of the vehicle while the engine runs fast to supply pressure hydraulic fluid to a lift ram for example. Pedal 30 and pedal 32, which operates a brake control master cylinder 31, are arranged so that they may be operated by one foot either separately or simultaneously. A pressure relief valve 22 is provided in the line between device 26 and the valve operators 14, 17 so that vehicle braking may be increased, once the clutches are disengaged, by further depressing pedals 30, 32 together. The Provisional Specification describes an arrangement (Fig. 3, not shown), which prevents inching unless the brakes are applied by connecting the outlet from master cylinder 26 with reservoir 27 through a valve which is closed only when the brake line pressure is sufficient to depress a spring-loaded piston within the valve.

Title: An improved method of producing impression foil
IPC: B32B27/00
Filed: 1937-10-16
Abstract: Relates to impression or embossing foil of the kind in which a film of metal, bronze powder, or colour is attached to a carrier or backing from which it can be stripped prior to or after the impression is made, and consists in employing two contacting layers of cellulose esters which repel each other, as follows: (1) the two layers are interposed between the impression film and the carrier; (2) one layer forms the carrier, and the other is interposed between it and the film; (3) bronze powder or colouring matter is incorporated with one of the layers, and the other is interposed between it and the carrier or itself serves as the carrier.  The two layers, which may consist of acetyl cellulose and nitro-cellulose can be separated when the carrier is to be removed.  In one method, a thin solution of a cellulose ester in a volatile organic solvent is applied to a paper backing, and, after the film has dried, a mixture of bronze powder or colour with a solution containing another cellulose ester is applied to the film; the second solution must not contain a solvent which will dissolve the cellulose ester in the coating below.  A film of metal or a coating of bronze powder is then applied and the finished bronze foil is detached from the carrier. In a modification, one or two layers of metal are formed galvanically on a metal band, a solution of a cellulose ester, which may be coloured with aniline colours, is applied, and a second cellulose ester solution is applied to form a carrier film.  The second cellulose ester coating may be a thick one, in which case the metal foil together with the first cellulose ester coating is pulled off the second coating and used as foil for stamping. Specification 428,800, [Group XXII], is referred to.
