Abstract: 101,884. Brulin, G. Oct. 19, 1915, [Convention date]. F o l d i n g bedsteads; folding seats.-A bed is formed by the combination of two folding struetures which are adapted for use as seats when separated. Each of the folding structures comprise bars 1 - - 4 pivoted together in pairs, which are connected by crossed links 5, 6 pivoted to the bars by means of anglepieces a - - a<3>. Detachable bars 10 support- 4 by ing canvas 9 are connected to the bars 1 - - 4 by means of tenons b - - b<3>. To combine two seats to form a bed, intermediate bars 13 supporting canvas are engaged by means of tenons with the ends of the bars 10. A head-rest comprises bars 15 supporting canvas and connected by a detachable bar 17. The bars 15 are pivoted at f and are held by catches g. Accidental detachment of the side bars from their supports is prevented by lugs c which engage studs d.

Title: Improvements in or relating to armouring for submarine cables
Inventor: PHEAZEY JOHN RICHARD
IPC: H01B7/14
Filed: 1958-05-09
Abstract: 864,842. Cables. STANDARD TELEPHONES & CABLES Ltd. May 8, 1959 [May 9, 1958], No. 14902/58. Drawings to Specification. Class 36. A submarine cable comprises a coaxial core surrounded by a serving of non-metallic material, with a plurality of armouring wires of high tensile strength carried in a non-metallic supporting medium and spaced apart around the served core, and an outer serving of textile material. The inner serving may be of jute with the armouring wires laid around this and spaced apart by P.V.C. separator strips with a binding of wire or tape to keep the structure in position. Over this an outer serving of jute is applied. The width of the separator strips is such that only enough armouring wires to provide the requisite longitudinal strength of the cable are used. Instead of the armouring being separated by strips it may be embedded in an extruded layer of P.V.C., or alternatively, sandwiched between two extruded layers. A further alternative is to thread the armouring wires into a textile webbing of high quality canvas impregnated with compound, or of plastics or glass fibre, and apply the composite webbing to the cable with a long lay. Two of such reinforced webbings may be applied one over the other with lays of opposite hand to provide a torsionally balanced armouring.

Title: Improvements relating to apparatus for the production of foam
Inventor: BEDFORD HOWARD EDWIN
IPC: A62C5/00
Filed: 1954-05-20
Abstract: 806.048. Mixing fluids in flow. PYRENE CO., Ltd. May 9, 1955 [May 20, 19541, No. 14906/54. Class 86 [Also in Group XXI] A fire-fighting crash tender providing high pressure air-foam jets from a projector 13 and from hoses connected at 14, 15, has a water tank 1, a foam solution tank 2 and a foam generator 8 of the injector type to which air is supplied under pressure from a blower 7 driven by the engine 4 of the vehicle, the blower shaft being coupled at 6 to a pump 9 which draws water from the tank 1 and delivers it to the generator through a pipe 17. The foam solution is drawn from the tank 2 by water passing 'to an inductor 10 through a pipe 23 branching from the pipe 17 and is delivered into the main suction of the pump 9. Foam from the generator passes through a pipe 11 to the projector 13 and hose connectors 14, 15. At maximum output, the blower and pump give the required relative amounts of air and liquid; at lower outputs, when excess air would otherwise be supplied, provision is made in the generator to bleed off the surplus air and so maintain the correct airliquid ratio. The generator comprises a casing 16 to which is connected the water-foam solution pipe 17, the liquid passing through an orifice 18 to mix with the air from the blower entering through a pipe 75. The liquid flow through the orifice 18 is controlled by a needle valve 21, the valve rod 38 of which can be moved axially by an arm 72 on a shaft 44 actuated from the cab of the tender. The air pipe 75 has a branch connected to the end of a casing 32 secured to the casing 16 and having an outlet 34 to atmosphere. The air flow in the branch pipe is controlled by a mushroom valve 36 carried on a rearward extension of the rod 38, the valve 36 being fully closed when valve 21 is fully open so that at full output all the air is delivered to the foam generator. If the demand for foam decreases, the valve 21 is partly closed, whereupon valve 36 opens to allow the surplus air to discharge through port 34, the engine speed being reduced as necessary to maintain a constant pressure in the pipe 17. The optimum proportion of foam solution in the water entering the generator is automatically maintained by mechanically linking the valve rod 38 to the movable throat member 26 of the inductor 10 which is of the form described in Specification 772,604.

Title: Improvements in conveying finely-divided solid material
Inventor: JENSEN EJLER
IPC: B65G53/12
Filed: 1951-06-25
Abstract: 689,537. Pneumatic discharge of hopper. SMIDTH & CO. AKTIESELSKAB, F. L. June 25, 1951. No. 15040/51. Class 78 (i). Material is fed into hopper 1 through inlet 2 and is discharged at the bottom by compressed air from pipe 7, the air entering at 38 to fill the top of the hopper and issuing as a jet at 46 to discharge the material. The air pressure is cut off before all the material is discharged, the remaining material being discharged by selfexpansion of the air in the hopper. The method of working is governed by arm 3 which, when the material piles up to a corresponding level, is displaced and, in turn, displaces lever 4 to lower the piston of valve 6. This permits compressed air from pipe 8 to flow to valve 10 and so to lower the piston of the latter. This permits air from pipe 8 to flow via pipe 13 to both pipes 14 and 15. The air in pipe 15 displaces valve 20 and thus maintains arm 3 in its displaced position after the material has sunk. The air in pipe 14 lowers piston 17 of cylinder 16. Piston 17, which actuates valves 25, 33, by the engagement of projections 23 with pivoted and spring-connected levers 24, 31, raises the piston of said valve 25 so as to break the connection through pipes 8, 28, 26 of air with cylinder 29 so that air valve 30 is closed. Piston 17 also lowers lever 18 and raises valve 19 to close inlet 2. The hopper is thus sealed. The fore-mentioned lowering of piston 17 also raises the piston of valve 33 and air flows from pipe 22 through pipe 34 to cylinder 36 so as to release valve 37 and to permit air to flow from pipe 7 into the hopper so as to discharge the latter. Before the material is completely discharged, the air resistance thereof falls so that the pressure of air in the system also falls. This releases valve 20 which allows arm 3 to fall. The air is consequentially cut off by cylinder 36 and the last portion of material is discharged by the self-expansion of the air inside the hopper.

Abstract: 183,017. Shotter, G. F., and Hill, E. W. May 31, 1921. Addition to 168,339. Induction motor meters.-The induction motor meter described in the parent Specification is modified for polyphase currents, and is shown arranged for a three-phase circuit. Unsaturated main shaded-pole electromagnets 1, 2, 3 are connected in the separate phases 4, 5, 6 of the load circuit and co-operate with metal discs 7, 9 to - drive a spindle 10. A permanent magnet 8 or a continuous-current eleotromtagnet acts on the dise 7, or a plurality of these may act on separate dises. The main magnets 1, 2, 3 may all act on one disc and may have parts of their magnetic circuits common. A number of sets, each consisting of an unsaturated main shaded-pole electromagnet connected in one phase of the load circuit, a constant-flux magnet, and a metal disc, may drive separate spindles having means such as differential gearing to add up their rotations. Each main magnet may have in series or parallel therewith a further shaded-pole electromagnet (not shown) acting on a. second disc, which is also acted on by a constant-flux magnet. One or more shaded-pole electromagnets connected across the supply mains may be provided to impart a small constant torques in the same direction as that due to the main magnets. One or more electromagnets which become saturated at high loads may serve further to retard the disc, and increase the proportionality of the meter at high loads. Each of these electromagnets is connected in series or in parallel with one of the main magnets and acts on the same disc as its corresponding main magnet. The meter may drive simple counting-mechanism or a demand indicator, as described in the parent Specification, in which the pointer is periodically returned to zero by a constant-speed motor consisting of a shaded-pole electromagnet connected across one phase of the supply mains and driving a metal disc.
