Title: Improvements in and relating to crimped or waved yarns and fabrics containing such yarns
IPC: D02G3/28
Filed: 1936-02-21
Abstract: 471,061. Yarns. DREYFUS, H. Feb. 21, 1936, No. 5277. [Class 120 (iii)] A composite yarn comprises a yarn of filaments or fibres to which crimps have been imparted doubled with at least one yarn of uncrimped filaments or fibres, so that the crimped yarn forms a spiral around the uncrimped yarn; the yarns may be artificial yarns of different characteristics, the crimped or imcrimped component of the yarn or both components may comprise continuous filaments of cellulose acetate, the uncrimped component may have been stretched prior to the doubling operation, e.g. in the manner described in Specification 370,430, and the doubled components may be bound together by a binding yarn, which may comprise uncrimped continuous filaments and which may be doubled with the doubled yarns in the same direction as that in which those yarns are doubled together. The stretched yarns may be subjected to a subsequent saponifying operation, e.g. as described in Specifications 402,141, 417,220, and 429,103, [all in Group IV], or to a subsequent shrinking operation, e.g. as described in Specification 389,823, [Group IV], or to both the saponifying and shrinking operations. The crimp may be applied to the component filaments or fibres of the crimped yarn by rollers and set by treatment with steam, by the method described in Specifications 424,880 and 442,073, by treatment with hot aqueous liquors when the yarns are of cellulose acetate and similar substances and particularly when the filaments are of substantially flat cross-section and the substance thereof contains para-dichlorbenzene or other plasticizing agent as described in Specification 459,781, or by any combination of these processes as described in Specifications 474,401 and 474,402. The crimp may be fixed in the materials by the process described in Specification 455,021 and the crimped filaments may be used as a yarn or cut into staple fibres which are spun alone or mixed with other filaments or fibres.

Title: Improvements relating to the protection of electrical conductors and equipment from the consequences of insulation failure, short circuits, and external damage
IPC: H02H7/22
Filed: 1937-02-22
Abstract: 490,242. Protective cut-out systems. KINNANE, R. F. Feb. 22, 1937, Nos. 5299 and 5300. Convention dates, Feb. 25, 1936 and March 27, 1936. [Class 38 (v)] In order to protect conductors and equipment from insulation failure, short-circuits, and external damage, one or more fusible, fault-detecting conductors are incorporated in or disposed in close proximity to the conductor or equipment and are arranged in a normally-balanced circuit ineluding a relay governing the operation of one or more circuit breakers. Fig. 1 shows such a conductor 10 connected in one arm of a normally-balanced Wheatstone bridge, across equipotential points of which the trip relay 14 is connected. The conductor comprises a loop of fusible wire or metal or metallizedpaper tape, and is arranged so that its two lengths lie close to one another and to the cable. The conductor may be applied to a radial or tee-off feeder, and its lengths may be arranged non-indnetively. A resistance 16 is provided for initially balancing the bridge, and a further resistance 16 ensures unbalance should a short-circuit occur in the conductor itself. The bridge may be energized continuously or intermittently, as by means of a relay 24 energized by a current transformer in the power circuit so that the protection device is dead when the cable is unloaded. With D.C. excitation, a condenser 25 shunts A.C. voltages away from the relay, and a condenser 26 additionally byepasses high potentials to earth, with rupture of the fuse 18 and consequent operation of relay 14. In Figs. 2, 3, 4 (not shown), the invention is illustrated in its application to a bus-bar and bushing insulator system a conductor section being wrapped in the form of a coil around each bushing, with the sections connected in series with one another and with the section disposed adjacent the bus-bars. When applied to a cable, the conductor may be transposed at intervals in its length, but in the single-core cable of Fig. 6, a metal tape 10 is doubled on itself and wound in bifilar fashion about the insulation. In a three-core cable, Fig. 8 (not shown), several sections of coil are located in grooves on the inside of the lead sheath, but the arrangement of Fig. 6 could be applied to this Figure and vice versa. An earthed metal screen or sheath may be disposed around the insulation of a conductor 10 to prevent the latter from collecting induced charges, Fig. 8 (not shown). Fig. 9 shows an arrangement for simultaneously operating two relays 14 when one conductor loop 10 is opencircuited. The far end of each loop is normally closed by contacts 33 of the relay 14 at that end, so that when that relay operates by unbalance of its bridge, it unbalances the other bridge.

Title: Devices for controlling the braking of vehicle wheels
IPC: B60T8/176
Filed: 1973-02-05
Abstract: 1363053 Aritiskid braking systems SOC ANON AUTOMOBILES CITROEN 5 Feb 1973 [8 Feb 1972] 5504/73 Heading F2F [Also in Division G1] In a vehicle antiskid system a signal representing the speed of a wheel is compared with a signal dependent upon that of the fastest wheel, a signal being generated from the ratio of these speeds, the fluid pressure in the braking system being reduced when the ratio falls below a predetermined value, the speed of the fastest wheel controlling a means 45a or 45b which varies this value so that it is lowered as the speed of the fastest wheel is reduced. Magnet pickups 27a-27d for the wheels 1a-1d supply pulses to frequency-voltage converters 28a-28d providing signals representative of wheel speeds which are fed to a comparator 29 which determines the fastest wheel. The signal representing the fastest wheel passes via a unidirectional conductor 45 to a memory 30 which stores data representative of vehicle speed. The memory output signal is applied to a generator 34 which multiplies the signal by a value between 0À7 and 0À8 and supplying a reference speed. The reference speed signal is compared by comparators 45a, or 45b for the front 3a, 3b and rear 3c, 3d wheel respectively, with signals representing the lowest wheel speed of the front and rear set, respectively as determined by comparator 29. The comparator 45a, 45b outputs are fed to further comparators 47a, 47b receiving signals from a sawtooth pulse generator 46 whose instantaneous output Ud varies. When the output from either comparator 45a, 45b is greater than Ud, a flip-flop 48a or 48b supplies a voltage which is amplified at 49a or 49b to operate a valve 5a or 5b which releases the brake pressure fed from a source 4 by way of a pedal operated valve 6.

Filed: 1963-02-12
Abstract: 1,043,591. Valves; pistons. V. BUSH. Feb. 12, 1963 [Feb. 13, 1962], No. 5751/63. Headings F2T and F2V. [Also in Division F1] In a free piston diesel engine driven hydraulic pump (see Division F1 the engine pistons 3, Fig. 1, are connected to the pump pistons 24 through rods 26 which are connected to each piston at its centre of gravity and are waisted, as shown, to permit self-alignment of the pistons. The piston-rods 26 are supported in hydrostatic bearings supplied with pressure liquid. The engine pistons may be gas lubricated and may be cooled by the liquid pumped, e.g. silicone oil, or by a separate coolant liquid. Alternatively, the pistons may be made of low-expansion material, e.g. porcelain, quartz or glass, or of nickel steel with a porcelain face, the porcelain being fused on a thin metal plate which is then brazed on to concentric rings formed on the piston face, the outermost ring being left free to prevent distortion. In a liquid cooled piston embodiment, Fig. 9 (not shown), the piston interior is connected to a pumping chamber by a conduit 167 and a bellows 172 is expanded and collapsed by the pressure changes in the pumping chamber so as to vary the volume of the piston interior and thereby circulate the liquid therein via valves 170, 171. A valve 177 controlled by a thermostat 178 controls communication between bellows 172 and the piston chamber 166. In another embodiment, Fig. 10 (not shown), the piston wall is formed with longitudinal bores 214 extending between end chambers 216, 217 connected to coolant supply and return passages 206, 207. A thermostatically controlled by-pass valve, Fig. 8 (not shown), for controlling the flow of coolant in the engine cylinder jacket and piston comprises a shuttle 131 acted upon by a spring 135 and a gas or liquid-filled bellows 133. The return from the cooling system passes through passages 138 and 140 via bellows 133. Coolant for the system passes through ports 136 and 137. When the engine is cold, coolant from port 136 is by-passed to passage 144. When the engine heats up, bellows 133 moves shuttle 131 downwardly to close by-pass 144 and open port 137. Spring 135 may be adjustable to adjust the operating temperature. The engine cylinder jacket coolant flow may be controlled in relation to piston coolant flow by a valve similar to that in Fig. 8, except that the spring is replaced by a further bellows and the piston return flow is passed over one bellows and the cylinder return flow passed over the other bellows. The valve shuttle is moved by the bellows to a position such that the piston and cylinder are maintained at the same temperature.

The piston 16 and cylinder 18 are held against relative rotation by pins 78. The distributer 12 has ports 48, 49 leading into grooves 45, 46 that are aligned with openings into the passageways 25, 28 to supply and exhaust the chamber 19. The distributer is separated from the surface of the extension 18a of the cylinder by a fluid bearing in which pressure fluid is supplied, via conduits in the distributer body, to circumferentially spaced cavities arranged in two groups 34a-34d and 35a-35d, the pressure fluid flowing axially from the cavities to collector grooves 52, 54, 60 and 61 which drain into a drain conduit 56. Any fluid passing axially past the grooves 60 or 61 is picked up by grooves 66 or 67 and flung centrifugally into further collector grooves 64, 65. Restrictive portions 39a-39d and 43a- 43d in the supply conduits control the pressure and flow to the bearing surfaces. Separate pressure fluid supplies are used for operating the piston 16 and supplying the fluid bearing. In an alternative embodiment (Figs. 4-6, not shown) a single pressure fluid supply is used for operating both the piston and the fluid bearing, some of the cavities of the fluid bearing being connected with the fluid supply passageway serving one end of the cylinder chamber and the rest of the cavities being connected with the passageways serving the other end of the cylinder chamber.
