Title: Improvements in the remote control of gas valves
IPC: F23Q3/00
Filed: 1935-05-24
Abstract: 446,555. Electrically-actuated gas valves. WEBB, T., and WEBB, J., 35, Claremont Grove, Didsbury, Manchester. May 24, 1935, No. 15120. [Class 135] An electrically-actuated valve for a gas burner comprises a valve member c carried by a hollow armature C of hardened steel, capable of being magnetized and permanently retaining such magnetism, which moves within a bobbin A on which is wound two solenoids A<1> and A<2> which are momentarily energized for opening and closing the valve respectively. These solenoids are enclosed in a casing B with end caps b of iron or steel and are arranged in a battery circuit with a switch E, of the type described for example in Specification 441,707, [Group XXXVII], so that either can be momentarily energized to open or close the valve, the residual magnetism retained by the armature C holding it in either position against one of the end caps b of the casing. An igniter filament g is included in the circuit of the solenoid A<1> so that the burner is automatically ignited on opening of the valve. Should the filament g be burnt out or broken the solenoid circuit A<1> will be broken and the valve will not open.

Title: Improvements relating to the manufacture of pipes and other articles of hollow crosssection
Inventor: SMITH HAROLD
IPC: B31C11/04
Filed: 1958-05-13
Abstract: 916,761. Pipe-making apparatus. PERMALI Ltd. May 4, 1959 [May 13, 1958], No. 15253/58. Class 99(2). Pipes and other articles of hollow cross-section are made by continuously advancing a core horizontally, coating the advancing core with a layer of reinforcing fibres, piping a liquid hardenable synthetic resin on to the fibres adjacent the core while they are being applied, hardening the resin and, if desired, withdrawing the core. As shown, the core 2 of a tube is formed continuously from an extruder 1 and is helically wound with fibres 17 from rotary heads 3 whereas fibres 27 are longitudinally applied from a stationary head 4. Resin is fed on to the fibres from devices 5, 6. A ribbon 37 of regenerated or modified cellulose film is applied on the fibres from a stationary head 7 and the tube is cured in an electrically heated annular chamber 8. The cured tube is drawn from the chamber 8 by a belt-roller assembly 38, 39 and is cut into convenient lengths by a blade 10. The heads 3, 4 carry annular plates 14, 23 on which are mounted bobbins 16, 26 from which the fibres 17, 27 are led on to the core over guide pulleys 18, 28 and through die apertures at the centre of rings 19, 29 supplied with synthetic resin which is fed on to the fibres through nozzles 20 leading from the rings. The head 7 also carries an annular plate 34 on which is mounted a reel 36 carrying the ribbon 37. The extruder 1 may be replaced by an apparatus for winding a paper or cardboard strip into a tubular core or by a bulk supply of preformed core. The chamber 8 may be replaced by infra-red or radio frequency dielectric heaters. The core 2 is solid or tubular and is formed of absorbent paper or cardboard, neoprene, polyvinyl chloride or a fusible alloy. The fibres are of glass, nylon, sisal or a polyester and are applied in the form of rovings, rovings tape, woven ribbon or tape. The resin consists of a mixture of a liquid polyester susceptible to cross-linking, a cross-linking agent such as styrene and a catalyst such as an organic peroxide or hydroperoxide and may contain an accelerator of cross-linking, such as cobalt naphthenate, as well as pigments and fillers. Alternatively, the resin is obtained from epoxy resin syrups, phenol-formaldehyde condensates, furane resin syrups or thiobal and polyurethane compositions.

In another form, which is preferably produced by plastic moulding, the bottom of the trap is constituted by an additional cleaning-cap. In a further form, Fig. 4, which may be cast, the cleaning-apertures 10 are disposed adjacent the bottom of the outletpassage. The outlet passage intersects the inlet at an angle of 35 or 55‹ and is overturned at its upper end. Both passages are suitably threaded and flanged.

Title: Improvements in or relating to the production of low-molecular weight isobutylene polymers
IPC: C08F240/00
Filed: 1950-06-19
Abstract: Polyisobutylene having a molecular weight above 10,000 and preferably between 10,000 and 20,000 is prepared by treating a light cracked petroleum fraction consisting of hydrocarbons having four carbon atoms in the molecule, and containing isobutylene together with substantial amounts of butene-1 and butene-2, to remove sufficient butene-2 that the ratio of secondary olefin to isobutylene is not substantially greater than 1 : 1 and the butene-2 content of the resulting product is not more than 20 per cent of the butene-1 content, and polymerizing the treated fraction at a temperature below 0 DEG  C. in the presence of a halide polymerization catalyst, preferably boron fluoride or aluminium chloride.  The butene-2 is preferably removed by fractionating the mixture to remove 50-90 per cent of the fraction overhead and using this overhead fraction for the polymerization.  5 per cent of substantially pure isobutylene may be added to the overhead fraction before polymerization, and about 0.1 per cent diethyl ether may also be added to increase the molecular weight. The polymers may be added to lubricating oils as viscosity improvers.

Abstract: 255,048. B³chi, A. July 11, 1925, [Convention date]. Railway locomotives, internal-combustion engine.-A power plant, particularly for vehicles, consists of an internal-combustion engine 2, one or more compressors 5 and an exhaust driven multi-stage turbine 11. Compressed air from the compressor 5, which is engine-driven, is supplied for normal charging by way of the conduit 7 to the inlet valves 8. Additional air is also supplied by a conduit 37 to a tank, from which it may pass into the engine on either the admission or the exhaust stroke, or directly to the turbine 11 by way of conduits 39, 40. The engine exhaust passes through conduits 10 to the turbine through valve controlled conduits 12, 13, 14. An equalizing vessel or steam generator 36 may be inserted in the conduit system 10. The flow regulating valves 12. 13, 14, 41, 42, 45, 46 are actuated from a common controller 47. At starting, air is drawn from a compressor 31, the compressor 5 and turbine 11 being byepassed by opening valves 33, 34 through the medium of levers and rods 35. Levers 32 control the fuel pump 30. The additional air may be compressed behind the engine piston and delivered to the engine cylinder on the exhaust stroke. In a modification in which the additional air enters the engine cylinder on the admission stroke, the compressor 5 supplies both the charging and the additional air by way of the conduit 7, and a doubly-seated valve is situated in the exhaust passage. Ahead and astern turbines may be driven by the exhaust gases. Both charging and additional air may be cooled before entering the engine cylin. der or the turbine casing.
