Abstract: 311,750. Micklethwaite, B. D. Feb. 16, 1928. Yarns, curling.-Apparatus for curling and de-curling yarns com- 'prises a frame a rotatable about a horizontal axis and having mounted therein a bobbin d, of the yarn or the like to be curled, rotatable about an axis at right angles to that of the frame, a tube c<1> at the front end of the frame a carrying, at its end farthest from the bobbin d, adjustable tension jaws through which the yarns to be curled pass to a pair of draw rollers v, v<1> rotated at a speed suitably lower than that of rotation of the bobbin d. The yarn is then wound on a swift w. A helical guide member k, Fig. 3, having end rings k<2> with radial slots for entry of the yarn, is arranged in the tube c<1> to prevent the curl from passing back to the bobbin. The tension is effected by spring plungers n, n<1> having end thimbles p, p<1>. A cap r having inner cam surfaces bearing against the thimbles is used to adjust the tension, a spring plunger s, engaging indentations in the cap, locking the latter in its set position. The drive of the machine is effected from the shaft h, a clutch member j, by engaging either of the pinions i, i' providing curling or de-curling. In starting the machine, the yarn is threaded through the tube c<1> and the rollers v, v<1> the latter roller being lifted temporarily by a hand lever so that a twist may be put into the untwisted end before winding commences. A series of curling spindles and draw rollers may be included in one machine.

Title: Improvements in Electric Motor Controllers.
IPC: H02P1/26
Filed: 1918-03-20
Abstract: 122,085. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). March 20, 1918. Controllers, polyphase.-In a polyphase motor controller which connects the motor to the supply through compensator windings for starting and through overload protective means for running the motor windings are permanently connected to the compensator windings at their tapping-points. The drum controller C has contact segments arranged in three sets corresponding to the three leads L<1>, L<2>, L<3> of the supply, and a hold-on coil 25 causes a latch 23 to hold the controller when it is in the running position. When the segments are moved to the left from the position shown in Fig. 1, the compensating-windings 1, 2 are connected across the phases L<1> L<2>, L<3> L<1>, and the motor is supplied from the lead L<1> and intermediate taps on the windings 1, 2. When the segments are moved to the right for running, the compensator-windings are disconnected and the motor is supplied directly from the mains. The windings of the overload relays 3, 4 are included in the circuits of the leads L<3>, L<2> and an excess current causes them to operate so that the winding 25 releases the latch 23 and a spring returns the controller to zero. In a modification, the change of connexions for a three-phase motor is obtained by using a three-pole double-throw knife switch. In another modification, Fig. 3, for a two-phase motor, the controller drum has four sets of segments corresponding to the four leads L<1>, L<2>, L<3>, L<4>, and the motor is supplied through the compensating-windings 56, 57 for starting and through the fuses 58, 59, 60, 61 for running.

Title: Improvements in or relating to the thermal treatment of hydrocarbons and furnaces therefor
Inventor: BRACONIER FREDERIC FRANCOIS AL
IPC: C07C4/04
Filed: 1957-02-15
Abstract: Unsaturated hydrocarbons such as acetylene and ethylene are produced by subjecting paraffinic and/or olefinic hydrocarbons to partial combustion in a furnace having a pyrolysis chamber which is of closed curvilinear <PICT:0840664/IV(b)/1> configuration in cross-section and in which a substantially continuous stream of inert fluid is helically swirled around, and in contact with the inside wall of the pyrolysis chamber substantially to prevent deposition of carbon and tarry materials on the wall of the chamber.  In one embodiment, a distributer ring 4 for fluid is positioned adjacent and below a disc-like distributer 1 for fuel and oxygen at the top of the combustion chamber 3.  Venturi-shaped conduits 2 extend transversely through the disc distributer 1 to form outlets for the fuel and an annular enclosed conduit 6 is provided to supply water.  Ring 4 is provided with helically arranged grooves 5, a connection being established between the annular conduit 6 and grooves 5 by an annular groove 7 of V-section.  Water is fed under pressure through an inlet pipe 8 into the conduit 6 and is ejected into the combustion chamber 3 so as to form a substantially continuous screen which prevents the formation of carbon.  Gaseous reaction products obtained by the partial combustion of the hydrocarbon are quenched by water which is injected transversely into the gases through a sprayer 9.  The product contained 7.2% of acetylene. Specification 756,606 is referred to.

Abstract: 334,191. Seguin, L., and Seguin, A. Dec. 3, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Stroboscopic apparatus.-In order to control the speed of an electric motor automatically to follow a timed escapement wheel, the escapement shaft 34 is driven from the motor .30 by reduction gearing to an intermediate shaft 52 bearing a pulley 58 and thence by an elastic and suitably guided pulley-band 57 to a smaller pulley 59 on the escapement shaft. The escapement shaft may, alternatively, be driven by a spring motor or a separate electric motor. The two shafts 34 and 52 respectively carry arms 50, 51 fitted with cooperating electric contacts in circuit with the motor and a resistance 42. Current is cut off or reduced whenever the arms separate and thus automatic regulation of the motor speed to equality with the average of the escapement speed is stated to be obtained. The motor may drive a time-indicator or a recording chronograph drum. In the apparatus shown in Fig. 1, the motor 30 regulates, by means of follow-up contact arms 7, 15, the speed of a larger electric motor 11 which drives a magneto-electric machine 28 adapted to produce flashes in neon tubes 6 applicable for stroboscopic gauging. The Specification describes a portable form of apparatus for this purpose in which all the moving parts are enclosed in a box having external plug-sockets for neon tube connectors.

Title: Improvements in Valves
IPC: F16K31/36
Filed: 1967-02-06
Abstract: 1,177,276. Valves. WHEATON BRASS WORKS. 6 Feb., 1967 [7 March, 1966], No. 5602/67. Heading F2V. In a flow control valve, flow from an inlet to an outlet is controlled by a piston 41 the position of which, with respect to its seat, being governed by a shuttle valve 35, a manuallyoperable pilot valve 36, a Venturi tube 32, disposed between the shuttle and pilot valves, a pressure regulator 30 and an auxiliary control valve 27. Depression of pilot lever 37 shuts pilot valve inlet A and opens outlet B with the result that fluid which maintains the shuttle valve piston seated is drained through ducts 69, 70, chamber 65 and line 66, which line opens towards the downstream direction of the valves. A corresponding line 60, opening towards the upstream direction and disposed in the valve inlet, serves to replenish fluid which has flowed out from the Venturi 32 through the now open shuttle valve 35, chamber 65 and line 66, the flow through the Venturi drawing in fluid from line 33 and so creating a vacuum in chamber 58 thereby permitting fluid pressure in the inlet line to raise piston 41 from its seat to initiate flow from the inlet to the outlet. Upon retracting pilot lever 37, pilot inlet A is opened and outlet B closed with the result that fluid from line 60 flows through inlet A, line 69 and acts on the shuttle piston to seat it. With the flow to line 66 closed off, fluid from line 60 flows through the Venturi and into line 33 wherefrom it passes through the pressure regulator 30 to chamber 58. Upon the chamber pressure reaching 80% of the fluid pressure at the inlet, the regulator automatically closes and a slower flow of fluid to the chamber takes place through valve 27, this arrangement serving to build up pressure in chamber 58 but in such a way that piston 41 is moved towards its seat initially at a rapid rate but slowly immediately prior to seating, so ensuring gentle seating. Valve 27 is arranged to allow rapid flow from the chamber 58 but only a slow flow in the opposite direction. A solenoidoperated valve (38, Fig. 3, not shown), having ports connected in parallel with those of pilot valve 36, is provided to permit electrical as opposed to manual, actuation of the system controlling the position of piston 41.
