Title: Yarns and like fibre assemblies
Inventor: BENSON WILLIAM
IPC: D01H4/16
Filed: 1967-08-15
Abstract: 1,240,470. Making yarns. COTTON SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. 1 Nov., 1968 [15 Aug., 1967; 16 Jan., 1968], Nos. 37459/67 and 2239/68. Headings D1F and D1W. A method of making a yarn or like fibre assembly comprises providing a nip between two surfaces moving continuously in opposite directions, causing fibres to accumulate continuously at a location in the nip with their axes substantially at right angles to the directions of movement of the surfaces, the fibres engaging the surfaces at said location, providing a fluid flow to assist twisting together of the fibres at said location, and withdrawing the material from said location as a continuous strand transversely to the directions of movement of the surfaces. Apparatus for carrying out the method comprises two continuously movable surfaces e.g. rollers 16, 20, arranged to form a nip and to move in substantially opposite directions in the region of the nip, means e.g. toothed roller 14 feeding fibrous material to the nip with the fibre axes substantially at right angles to the directions of movement of the surfaces 16, 20, means for providing a fluid flow at the nip to assist twisting the fibres together, and means for drawing off the material as a continuous strand transversely to the directions of movement of the surfaces. The surface 14 is a licker-in roller and the surface 16 a perforate cylinder. In operation, the fibrous material e.g. carbon fibres, are fed to a conveyor 10 in the form of spread bundles. The fibres pass over a transversely moving spiked conveyor 21 to a pair of soft rubber covered rollers 12. The distance between the licker-in roller and the rollers 12 is adjusted to give the length of fibre required. The fibres are then carried on the cylinder 14 with an accompanying air stream to the cylinder 16. The air flow through the cylinder 16 is controlled by baffles 18 to give a divergent air flow at the transfer point so that the fibres are transferred to the cylinder 16 and lie transversely to the direction of movement. The fibrous material accumulates at the roller 20 causing the fibres to roll around each other as they are drawn off transversely and so the twist of each fibres about its own axis is reduced. The yarn may be consolidated between transversely oscillating endless belts or may be treated with polyvinyl alcohol.

Title: Process for purifying fluids
IPC: C07C7/11
Filed: 1960-06-28
Abstract: Hydrocarbons containing hydrogen sulphide and carbonyl sulphide are purified by intensely mixing with an aqueous solution of one or more dipropanolamines for at least 15 seconds at more more than 70 DEG C. and recovering the hydrocarbons.  If a gas, the weight ratio of hydrocarbon to the dipropanolamine phase may be 1:10 to 20:1 and the contacting is effected in a column provided with bubble trays or packing material.  When liquid or liquefied the volume ratio of hydrocarbon to the dipropanolamine phase is not less than 1:10, preferably about 1:2 and may be contacted in two or more stages mixed in each stage with a propeller mixer or centrifugal mixer such as a turbo-mixer or Ultra-turrax-mixer transferring 0.2-1.5 kilowatts per cubic metre of mixture of mechanical energy from the stirrer to the mixture.  The dipropanolamine preferably is or contains di-isopropanolamine, the solution strength being 10-60% by weight. The solution may also contain triethylene glycol or 2-methoxy ethanol.  The temperature may be 0-70 DEG C. and the contact time up to 30 minutes. Ethane, propane or butane fractions may be treated as liquids, e.g. propane at 25 atmospheres or butane at 10 atmospheres. The dipropanolamine solution is readily regenerated by heating to 70-130 DEG C. preferably to cause boiling, the steam evolved stripping the solution.  Specification 803,043 is referred to.

Title: Brake system
IPC: B60T13/52
Filed: 1962-01-23
Abstract: 938,522. Fluid-pressure brakes. BENDIX CORPORATION. Jan. 23, 1962 [Feb. 9, 1961; Feb. 13, 1961], No. 2473/62. Class 103 (1). A fluid-pressure braking system comprises separate service and emergency systems for applying the same brake, each system having a brake motor and conduit means, a pressureproducing device which normally operates the service system, a fluid pressure storage device, means permitting charging of the storage device by operation of the pressure producing device, and valve means for actuating the emergency brake system by fluid under pressure from the storage device upon failure of the service system. In one embodiment, the service system comprises brake motors 24, 26 for the front and rear brakes of a vehicle, a conduit system 18 and a master cylinder 16. The energency system comprises brake motors 44, 46, a conduit system 42 and a hydropneumatic reservoir 32 containing air under pressure. A pedal 14 operates the master cylinder 16 and a second pedal 34 operates a valve 36 to connect the reservoir 32 to the conduit 42, the valve in its inoperative condition connecting the conduit 42 to the master cylinder reservoir. A second valve 48 is operated by hand via a cable 58 to connect the master cylinder 16 to the reservoir when this requires charging as indicated by a pressure-sensitive switch 52 illuminating a lamp 54 in a circuit controlled by the ignition switch 55. In its inoperative condition the valve cuts off the reservoir 32 from the master cylinder and connects the latter to the conduit system 18. A check valve 60 prevents return flow from the reservoir back through the valve 48. A cable-operated latch 62 is provided so that the emergency system can be used as a parking brake. In normal operation, braking is effected by use of the pedal 14, there being a projection 68 on the second pedal 34 which is normally located beyond the range of movement of pedal 14, but which is engaged by the pedal 14 when the latter moves beyond its normal range owing to failure of the service system, whereby the emergency system is automatically operated. In a second embodiment, Fig. 4, the service and emergency systems are as in Fig. 1 excepting that the reservoir 32<SP>1</SP> is automatically recharged during each operation of the master cylinder 16<SP>1</SP> by a pump comprising a stepped piston 72 containing a checkvalve 80 which co-operates with a check-valve 86 in pumping fluid from the conduit system 18<SP>1</SP> to the reservoir, a pressure limiting valve 88 being arranged, between the reservoir 32<SP>1</SP> and the master cylinder reservoir to return surplus fluid when the reservoir 32<SP>1</SP> is fully charged. In a modification, Fig. 5, pumping is effected by a spring 182 acting on a stepped piston 172 cooperating with check valves 180, 186 respectively, arranged in a conduit 183 leading from the master cylinder reservoir and a passage 181 leading to the reservoir 132<SP>1</SP>. A relief valve 188 is provided but this may be omitted as spring 182 determines maximum pumping pressure.

Title: Improvements in or relating to electronic relays and wave generators
IPC: H03K17/54
Filed: 1944-02-18
Abstract: 594,343. Pulse generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 18, 1944, No. 3024. Convention date, May 30, 1942. [Class 40 (v)] In a switching device the grids of a first and second valve are connected in parallel respectively with the grids of the third and fourth valves,a direct connection being provided between a collector electrode in the first valve and a collector electrode in the third (or fourth) valve, the second valve being similarly connected to the fourth (or third) valve, time delays means being associated with the grid of each valve. The relay is arranged to have one stable state with the third (or fourth) valve conducting, the remaining valves being non-conducting. Upon the application of a triggering pulse, the first (or second) valve is rendered conducting, causing the third and fourth valves to reverse their states and after a delay the relay assumes another stable state with the fourth (or third) valve conducting. Valves 22, 26 are cross-connected by resistances so that with valve 22 conducting, valve 26 is biassed beyond cut-off, and due to the connections between the grids, valve 36 is biassed more negatively than valve 39, resistances 43, 45 maintaining the cathodes of valves 36, 39 sufficiently positive to prevent anode current. Valve 102, operating as a blocking oscillator, feeds a negative triggering pulse to the cathodes of valves 36, 39, causing the valve 39 to conduct, the fall in anode potential reversing the conducting state of valves 22, 26. The grid potentials of valves 36, 39 remains substantially unchanged throughout the pulse due to the condenser resistance delay networks 37, 38 and 40, 41, the condensers charging or discharging slowly towards the new potential of the grids of valves 22, 26. The next-triggering pulse is effective to cause valve 36 to conduct and return the relay to its original state. In a modification, Fig. 2 (not shown) the anodes of the valves 36, 39 are connected to the screen grids of pentodes operating as a trigger pair. In a further modification, Fig. 4 (not shown), the triggering signal is fed to the control grids of valves 36, 39. The blocking oscillator 102 may be synchronized by signals applied to terminal 104 and feeds a saw tooth output through amplifier 103 to the cathode ray tube deflecting plates 81. The square wave output from valves 22, 26 is fed to the suppressor grids of gating valves 96, 97 to allow them to amplify, during alternate sweeps, the signals applied to their respective grids the output signals being fed to deflecting plate 82<1>. To displace alternate traces, a part of the square wave is tapped off from the valves 22, 26 and applied to the deflecting plate 82.
