Patent GB-182592-A (GB)
Title: Improved electrically actuated mechanism for producing sliding or rotary motion
IPC: B63H23/24
Filed: 1921-04-19
Abstract: 182,592. Bray, E. N. April 19, 1921. Steering-gear.-A power transmission system for steering ships comprises two motors having their armatures mounted upon the same or upon interconnected shafts, rotatable field systems connected to the mechanism to be operated, and a regulator or regulators for varying the excitation of the fields. The armatures a, Fig. 1, of two motors are mounted upon a common shaft b and the rotatable field systems b are connected to bevel-wheels f gearing with a wheel g on the shaft h to be controlled. Normally the field excitations of the motors are equal and no movement of the shaft h occurs. The operation of the regulator h<1>, Fig. 3, disturbs the balance of the field excitations and the shaft h is operated. The movement of the shaft h operates the regulator i until the balance is restored. In the modification shown in Fig. 4 a single regulator k is employed. The regulator k is connected by a link n to a crossarm m pivoted to two operating arms l, l<1>. The operation of the arm l disturbs the balance of the fields and the movement of the controlled apparatus operates the arm l<1> to restore said balance. In a modification shown in Fig. 2 the shaft q to be controlled is geared to one field system by a chain p and to the other field system by spurgearing o. The regulator may be controlled electro-magnetically.

Abstract: 455,282. Electric incandescent lamp filaments. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG, Ujpest, near Budapest. April 15, 1935, No. 11576. Convention date, April 14, 1934. [Class 39 (ii)] A metallic tungsten powder, particularly for the manufacture of thick filamentary incandescent bodies, comprises not more than 1 per cent by weight of alkali metal oxides, and not more than 4 per cent of metallic tin or of an oxide of tin or a mixture of these substances. The added substances are mixed either with tungsten powder or with the material from which the latter is prepared, e.g. tungstic acid; in either case they are removed during the heat treatment incidental to manufacture of the bodies. In an example, a solution of tungstic acid hydrate is mixed into a sludge with solutions of sodium and potassium chloride and ammonium chlorostannate, and the sludge evaporated and dried. The resulting substance is reduced in hydrogen at 820‹ C., and the material so formed pressed into rods, heated in hydrogen to 1100‹ C., sintered in hydrogen by means of a lowvoltage current, hammered, and drawn, and, if required, coiled into spirals.

Title: Improvements relating to the projection of inflammable material
IPC: F41H9/02
Filed: 1941-09-11
Abstract: 583,025. Liquid-fuel burners; igniting burners. FRASER, R. P. Sept. 11, 1941, No. 11663. Divided out of 583,023. [Classes 75 (i) and 75 (iii)] [Also in Group XXI] An ejection device for inflammable liquid particularly for use as a flame thrower in war, comprises an internally tapered nozzle, having a central tapered valve opened by the pressure of the liquid, acting on a piston on the valve stem and means for igniting the liquid. The central portion may be hollow to allow a readily inflammable liquid, such as petrol to be discharged therethrough to cause ignition of the liquid later discharged through the annular space in the nozzle after the central plunger has been retracted. When a solid plunger is used, however, the liquid is atomised at the nozzle and mixed with air and is then readily ignitable at the beginning of the discharge and is ignited by an igniter 41 on the nozzle; a cross jet of petrol from a nozzle 40 may however be directed across the stream to aid the ignition. The central plunger is tapered at'its rear end to increase the velocity of the liquid at the nozzle and the rod 3 has a piston 42 at its rear end adapted to be retracted against spring resistance to abut' against an adjustable stop 45 by the pressure of the liquid supplied through an aperture 43 from the supply vessel, which is subjected to pressure of carbon dioxide. For high pressure svstems the release and shut off valve for the liquid may be automatically actuated by a plunger 33 movable in a cylinder under the pressure of the gas. The valve consists of an obturator 29 and a gate valve 30, Fig. 4. The valve rod may actuate a switch 38 through a lever 34 to cause ignition of the liquid by a device 41 disposed at the nozzle and simultaneously a jet of petrol from a pump 40 may be projected across the stream of liquid by another lever also actuated by the valve rod. Specification 583,023 is referred to.

A spring ring 17 tends to expand the segments and a spring ring 21 in the housing engages notches 14 in the segments tending to retain them in the closed position. Pins 22 engaging between the segments assist in guiding them and engage the ring 17 to prevent complete separation. In a modification, two sets of polygonal surfaces 28a, 28b, Fig. 4, are provided with an intermediate conical surface 29a on the housing, and the segments have two sets of conical and two of polygonal surfaces. Spring detent pins 31 replace the ring 21. In a further form of segment having only one central conical portion slight projections are formed that tend to retain the housing in the closed position.

Class 7(2) [Also in Group XXIX] A hydraulic coupling for driving the radiator cooling fan 30 of an internal combustion engine comprises a disc 32 splined to an input shaft 29, and a housing 26, 27 forming the output member of the coupling and including a partition 35 which separates a reservoir 33 from a working chamber 31. The housing is driven by the viscosity of a film of liquid between the disc and the adjacent walls of the working chamber. An annular reservoir 34 is provided in the part 26. The partition 35 is provided with inlet ports 37 controlled by a valve plate 38 which is biased by a spring 41 to close the ports and is opened by a shift pin. 47 controlled by an. element 50 responsive to the temperature of the engine coolant. The partition has restricted outlet ports 36 adjacent its periphery. On starting, and with the engine coolant cold, the inlet ports 37 are closed, and liquid in reservoir 34 and chamber 31 is discharged through the ports 36 to the reservoir 33. The housing and fan remains substantially stationary. When the engine heats up the element 50 displaces the valve plate and so opens the inlet ports 37, and liquid enters the chamber 31. A film of liquid is built up between the adjacent faces of the disc 32 and the walls of the chamber and the housing is rotated. The periphery of the disc is notched to form vanes 44, and the walls of the chamber formed with guide ring 45, 46, to direct the liquid between the vanes. This facilitates a cooling circulation of fluid through the ports 36, reservoir 33 and ports 37 back to the working chamber. The disc may be provided with cork facings to prevent metal to metal contact. The input shaft 29 has fast therewith a coolant pump rotor 13 and a pulley 23 belt-driven from the engine crankshaft. The disc 32 may be the output coupling member and the housing 26, 27 the input coupling member.

Title: Improvements in working fillers and/or oil extenders into elastomers
IPC: C08J3/21
Filed: 1961-04-05
Abstract: Fillers and/or oil extenders are worked into elastomers obtained by polymerization of monoolefins with/without polyolefins using co-ordination (Ziegler) catalysts, by adding the filler and/or extender to the crude elastomer solution in inert diluent resulting from the polymerization, and then separating the compounded elastomer.  The elastomer may be derived from ethylene, propylene, butylene and/or butadiene, isoprene or trivinyl hexene, and the fillers/extenders specified are carbon black, silicates and high boiling hydrocarbons obtained in the refining/distillation of petroleums.  Inert diluents disclosed are aliphatic and aromatic hydrocarbons.  The compounded elastomer may be recovered by dispersing the filler/extender/elastomer solution in water, which may contain a dispersing agent or emulsifier, steam distilling off the diluent, optionally blowing air into the aqueous dispersion, and then coagulating if necessary to obtain the product.
