Abstract: 486,315. Gyroscopic apparatus. MOSS, D. G. K., and PEIRCE, H. C., (trading as MECHANISM). Dec. 1. 1936, No. 32999. [Class 97 (iii)] In a gyroscopic navigational instrument a representation s of the supporting craft and a representation h of the horizon are moved by the gimbals in opposite directions when the craft departs from the horizontal. Fig. 1 shows the application to a gyro-vertical of the type described in Specification 441,130. A channel sectioned ring r having an arcuate portion carrying a representation s of an aircraft and lying over the dial o, fixed to the outer gimbal d, pivots on a bracket g, fixed to the instrument casing, on an axis r<1> normally coinciding with the axis c of the rotor casing b. The ring is caused to move up and down over the dial o by the engagement in the channel of the ring of an arm n fixed on the casing b and passing through a diametrical slot o<1> in the dial o. An horizon bar h arranged between the ring r and dial o is pivoted to the outer gimbal d at h<1> and is engaged by pins i on the casing b which cause it to be lowered when the ring r is raised and vice versa. A diamond shaped indicator n<1> on the arm n is normally masked by the representation s but comes into view when the craft is simultaneously banked and inclined fore and aft.

Title: Electro multiplier tube
IPC: H01J43/20
Filed: 1938-11-14
Abstract: 521,299. Electron multipliers. PARKSWORTH TELEVISION, Inc. Nov. 14, 1938, No. 33038. Convention date, Nov. 29, 1937. [Class 39 (i)] An electron multiplier has around the first electron source 9 an annular cup 16, with a secondarily emissive inner surface and an electron-permeable part 15 around the source, a conical secondarily-emissive electrode 19 coaxial with the cup and with its apex pointing thereto, a third secondarily-emissive electrode 17 near the cup and lying in the path of lines normal to the surface of the cone, a Faraday cage 24 between the cone and the cup and third electrode with electron-permeable portions 30, 26 near and parallel to the surfaces of the cone and third electrode, a control grid 11 and a collecting anode 4. The electrode 17 is annular and so placed as to lie within the major portion of the annulus defined by lines drawn normal to the cone at its apex and basal periphery. In the form shown, the cage has large openings 25 so that ocaesium vapour may readily enter inside and the cathode, which is indirectly heated at 7, has an upper disc 29 within an opening 27 in the lower screen 26. The cathode is at earth potential and the effect of the disc and opening 27 is to produce a field within the cage which prevents the electrons from crossing the middle of the space and meeting the second stage 19 at an unsuitable angle.

Title: Switching stages and selecting arrangements including such stages
IPC: H03K17/62
Filed: 1962-08-28
Abstract: 1,014,182. Automatic exchange systems. SIEMENS & HALSKE A.G. Aug. 28, 1962 [Aug. 29, 1961], No. 33074/62. Addition to 888,196. Heading H4K. In a selecting stage of the hunting circuit described in the parent Specification, the transistors linking the inputs to the outputs of the stage are replaced by a transformer. The transformer comprises a magnetic core having a rectangular hysteresis loop, which core can be triggered into a " positive " or " negative" magnetic state in dependence upon the currents flowing in the windings surrounding it. Initially those stages which are free have their on contacts closed so that on the occurrence of a " hunting start " pulse at the input w of a monostable circuit K3, current will flow in the input windings e of all such stages. Each winding e is connected to the coupling output k2 of its stage so that in all stages succeeding the first free one (B, say) current will flow in their blocking windings s, thereby preventing operation of the succeeding stages irrespective of the presence or absence of current in their windings e. Due to the change of state of core T in stage B a current pulse is induced in an output winding g2 thereof, which pulse is then shaped in circuit F and thereafter applied as an inhibiting pulse to circuit S. When the pulse decays, circuit S triggers monostable circuit K2 thereby immediately resetting K3 and applying an interrogation pulse to windings f of the transformers. The latter pulse causes the operated core (B) to restore whereby a current pulse is induced in winding g1 thus enabling bi-stable circuit K1 and causing a marking potential to appear on its output Z<SP>1</SP>. Circuits K1 may be reset at the end of a hunting operation by the application of a suitable pulse to terminal r. If, after hunting has commenced but before K3<SP>1</SP> is reset, a stage (A, say) preceding the operated stage (B) becomes free (contact m operates) then the current now flowing in its (B) blocking winding s tends to drive the core back into its original state but the current in winding e of the preceding stage A is at this time insufficient to set its core. When stage B reaches its original state, the current flow in winding e of stage A an increase sufficiently to trigger its core, the marking operating then continuing as described above.

Title: Improvements relating to vent valves for compressed fluid braking apparatus
IPC: B60T15/54
Filed: 1958-10-17
Abstract: 850,450. Vent valve for fluid pressure brakes. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. Oct. 17, 1958 [Oct. 26, 1957], No. 33169/58. Class 103 (1). A vent valve device for compressed fluid braking apparatus, comprises chambers 6, 7 for connection to an auxiliary reservoir and a brake cylinder respectively, and connected by a passage 5 closable by a valve 11 controlled by a piston 8b coaxially slidable in a piston 8a which normally closes a vent passage 12 between chamber 7 and atmosphere, the pistons being exposed to atmosphere on one side and on the other to brake pipe pressure acting to maintain valve 11 open and passage 12 closed, and a manually operable member 19 by which the pistons can be moved to close valve 11 and open passage 12. With the apparatus on a railway vehicle, the brakes are normally applied on separation of the vehicle from the train, to release the brakes, operation of member 19 moves pistons 8a, 8b via plunger 20 against springs 14, 21 to uncover port 13 and connect passage 12 to a reduced diameter portion 15 of piston 8a, ports 18 and atmospheric chamber 22 to vent the brake cylinder only to release the brakes, the passage 5 being closed by valve 11. The pistons are held raised by escaping fluid acting on the lower face of piston 8a and by auxiliary reservoir pressure acting on the lower face of valve 11 which is fixed by rod 9 to piston 8b. When a truck has been reconnected with a train, the brake pipe pressure rises and acts through a connection, not shown, to lower the pistons 8a, 8b, close passage 12 and open valve 11. The rod 9 is a loose fit in bore 10, permitting the venting of chamber 10a to atmosphere via duct 9a, sealing rings 11a prevent fluid escaping to duct 9a from the auxiliary reservoir when valve 11 is closed.

Abstract: 732,336. Circular looms. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE & DE MECANIQUE. Nov. 30, 1953 [Nov. 28, 1952], No. 33199/53. Class 142(2). Heald frames 8, arranged in concentric rows in a circular loom, are operated by bellcrank levers 10, which are acted on, before each shuttle passes the heald frame, by push rods 33 riding on a cam 34 and having heads 32 entering recesses 31 in the levers. If a heald frame is to remain down, the bellcrank lever is engaged by a latch 36 (which continues to hold the lever after its operating magnet 38 is de-energised) ; if the heald frame is to be up it returns to the position shown as the push rod 33 recedes into a low part of the cam 34 ; if the heald frame is latched down and is required to go up, the push rod, when it encounters the bellcrank lever pushes it sufficiently for the latch 36 to fall clear. One push rod 33 operates the bellcrank levers associated with several heald frames, one from each row, but each bellcrank lever has its own latch 36. For simple weaves, the latches 36 are omitted, and individual rods 33 are pivoted to the bellcrank levers, there being a separate cam 34 for each row of healds. Each section of the shedding mechanism, comprising a heald frame from each row, with their associated bellcrank levers, push rod(s), and latches (if any), are mounted in a separate casing, the casings being disposed in a circle round the loom.

Abstract: 1,129,045. Coated fabrics. KURASHIKI RAYON K.K. 25 July, 1966 [23 July, 1965], No. 33438/66. Heading B2E. [Also in Division Dl] A non-woven leather-like fabric is made by initially setting a random fibrous web with a binder, impregnating and/or coating the set web with an elastomeric polymer solution, coagulating the polymer by treatment with a liquid which is miscible with polymer solvent but which is non-solvent for the polymer, then extracting the initial binder with a solvent which is a non-solvent for fibres and the polymer. The fibres can be needle punched to form the web. The set mat can be pressed, e.g. with rollers at 120C. and buffed before impregnating. The web may be impregnated by squeezing in a solution of the polymer. The web can be impregnated and/or coated with two amounts of polymer. The fibres can be made of polyamides, e.g. drawn and crimped nylon-6 fibres, polyesters, polyacrylonitrile, polyvinyl chloride, fibres made by spinning a mixture of these polymers, graft fibres, natural fibres or a mixture thereof. The polymer can be a polyurefhane elastomer e.g. the reaction product of polyethylene-polypropylene - adipate-glycol, p, p' diphenylmethane diisocyanate and ethylene glycol, N-methoxymethyl-polyamide, acrylonitrile - butadiene, copolymer, ethylene-vinyl acetate copolymer or natural or synthetic rubber. The polymer can be dissolved in dimethylformamide together with sorbitan monostearate and stearyl alcohol to form the impregnating solution. The binder can be polyvinyl alcohol, watersoluble starch, carboxymethyl cellulose, partially saponified acrylates, polyacrylamide, cellulose acetate, polyvinylacetate or polyvinyl chloride. The binder can be removed with water at 80C or methanol. The impregnated web can be coloured, softened, embossed and coated with a polymer.

Title: Improvements in or relating to telephone or like systems
IPC: H04Q1/36
Filed: 1936-12-07
Abstract: 486,554. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., SAVILLE, W., and WILLIAMS, A. H. Dec. 7, 1936, No. 33549. [Class 40 (iv)] In a mechanical impulse repeater or regenerator as described, for example, in Specification 458,095, if the apparatus becomes full to capacity or is unable to take a further digit of maximum value, contact springs are operated to release the apparatus and transmit a busy signal or to connect in a second regenerator. The system shown is similar to that shown in Figs. 4 and 5 of Specification 467,442 in which the sending out of the stored impulses is made dependent on the receipt of a signal from the incoming end of a junction. If the receiving disc R makes a complete revolution relatively to the sending disc . S, i.e. takes 40 steps, the off-normal contacts N1 are again opened by means of a cam device and, before the relapse of relay C, relay BR operates in series with relay BY to connect up busy tone, open the outgoing junction circuit, and short-circuit relay IP so that the stored impulses are sent out into an open circuit. In a modified system, otherwise similar to that shown, the off-normal contacts are opened after 31 steps and the relay BR energizes a relay which switches over the impulse receiving circuits to a second regenerator. When all the impulses stored by the first regenerator have been transmitted, the release of relay BY by the opening of contacts N1 connects up a further relay which switches over the retransmitting circuits to the second regenerator. The system may be arranged to give a busy signal if the second regenerator becomes full to capacity.
