Patent GB-132854-A (GB)
IPC: D01H1/36
Abstract: 132,854. Ashworth, S. S. Sept. 23, 1918. Driving - arrangements; building-motions.-An improved device for equalising the twist given to yarns &c. as they are wound at varying diameters upon bare spindles or tubes, bobbins, &c. by varying the rate of speed of the delivery rollers comprises a cam having a varying longitudinal surface, a lever operated by the cam and moving relatively gradually along it, and a second cam operated by the le.ver and moving a beltguide over conical pulleys. A device is provided to drive the delivery rollers at a minimum speed when the usual driving-mechanism fails to act. The front roller shaft h, Fig. 2, is driven through gearing g, g<1>, g<2> from the upper conical pulley a, which is driven by a belt d from the lower pulley b, which derives its motion from the twist wheel c. The belt d is moved across the pulleys by guides carried by a frame e moving on guides e<2>, f. The frame c is traversed by a lever m operated by a cam-slot n<1> in a plate n on the shaft of which is a chain wheel o by a chain o<1>, weighted at one end. and attached at the other to a lever o<3> controlled by a cam p. To provide the necessary variation during the building of the cop. the cam p, Fig. 3, is of considerable length and has a varying profile. The cam is rotated by gearing and makes one revolution for each revolution of the building-motion cam. It is traversed relatively to the lever o<3> by a nut p<2> engaging a rotating screw p'. Rotation is imparted by a plate p<5> on the screw, pins p<4> secured to the cam passing through holes in this plate. The cam p is of conical shape at the. end engaged by the lever whilst the cop bottom is being built. The part employed during the building of the body of the cop is nearly cylindrical, but to compensate for the taper of the spindle the surface p<9> of the cam nearest to the axis of rotation is at a slight angle to that axis. The shaft h of the delivery roller carries a ratchet wheel h<6> engaged by pawls h<5> carried by a gear h' loose on the shaft. The gear h<1> is driven from the twist wheel c and normally the ratchet wheel h<6> overruns the pawls. Should the belt drive fail, the ratchet then drives the front roller shaft. The point of the lever o<3> which engages with the cam p may be traversed instead of traversing the cam. In winding bobbins in cylindrical layers with a gradually shortening traverse to form the. nose, the cam p, Fig. 4, is disconnected from the screwed part of the shaft and is fixed thereon bv a set-screw p<11>, and the shaft is rotated slowly by a ratchet to make one complete revolution during the whole of the building of the bobbin. According to the Provisional Specification, a cam of the same shape as the cam p may be employed as the building- motion cam.

Title: Improvements in wire-drawing machines
IPC: B21C9/00
Filed: 1923-05-18
Abstract: 217,734. Western Electric Co., Ltd., (Western Electric Co., Inc.). May 18, 1923. Drawing wire. - A wire-drawing machine comprises a box-frame 14 on the back 13 of which is mounted a pair of parallel shafts 18, 20 in the same vertical plane, the upper shaft carrying a series of independent, loosely-mounted sheaves 19 of uniform diameter and the lower shaft having secured thereon a stepped capstan 17. The shaft 18 is driven through gearing by a motor secured to the framework. The wire is taken from a spool 50 round guide pulleys 51, 52 and thence round the sheaves 19 and capstan 17 in such a manner as to progress from the smallest to the largest diameter of the latter. The wire is finally taken from the capstan round an adjustable roller 57 and a roller on a lever 60 to a driven spool 61. The drawing-dies are located between the capstan and sheaves and are arranged in two staggered tiers 53, 56, Fig. 5, slots being provided between the dies of each tier to allow the passage of the wire. The dies are mounted in shelves 23, 26 carried by a box 22' containing a valve 30 which is operated by a rocking lever 40 to allow lubricant to be circulated from the well of the main frame 14 through a pipe 36 and pump 35 to the box 22<1> from whence it issues in jets directed on the drawing-dies.

Title: Improvements in or relating to apparatus for recording television pictures
IPC: H04N5/84
Filed: 1957-04-26
Abstract: 849,834. Automatic speed control systems. FERNSEH G.m.b.H. April 26, 1957 [April 27, 1956], No. 13355/57. Class 38 (4). In an apparatus for recording television pictures including an intermittent-motion film camera 31, Fig. 1, for recording alternate frames only of the display on tube 3, control of the motor 25, 26 driving the camera 31 is effected by a sinusoidal oscillatory voltage 13, Fig. 2, derived from a square wave 5 of half the periodicity of the time-base from which it is developed which also brightens the reproduction of alternate frames, the phase of the sinusoidal voltage being controlled to ensure correct phasing by the output of a discriminator 35 fed with the square wave 5 and the output 34 of a tachometer generator 32, 33. The square wave 2 derived from the time-base by a unit 1 is amplified in valve 4 and applied to an integrating circuit 6, 7, 8 to produce the sinusoidal wave 13 across transformer 12, and positive halfcycles are passed by valve 14 to produce a substantially square wave 15, the space-to-mark ratio of which is controlled by resistor 16. A differentiation stage 17 yields two sequences of trigger pulses 19, 20, mutually displaced by 180 degrees across the secondary of transformer 18 which control push-pull inverter 21, 22 to produce across inductor 23 a 25-cycle oscillation for energizing rotor windings 25, a rotating field being artificially created by a condenser 27. A resistor 29 included in the stator winding during starting is replaced by a battery 30 when a relay is operated as a result of the motor reaching its desired speed. A lack of synchronism is reflected by a change in the D.C. output of discriminator 35 to the grid of valve 37 whereby a correction in the phase of the motor supply is effected.

Title: Method of lining pipes and vessels with polymer plastics
Inventor: CHARLESBY ARTHUR
IPC: B29C63/00
Filed: 1956-05-02
Abstract: In a method of lining rigid, cylindrical pipes or vessels of metal, rigid thermosetting plastic, fibre glass or glass, a tubular liner of a polymer plastic, e.g. polyethylene, polyvinyl chloride or polyvinylidene chloride, and having an outside diameter smaller than the inside diameter of the pipe to be lined is inserted into and swollen or otherwise expanded into contact with the inside wall of the pipe, the liner being subjected, either before or after insertion into the pipe, to the action of high-energy electrons, gamma rays or X-rays, the radiation dose being sufficient to increase the temperature resistance of the plastic over that of the unirradiated plastic without causing appreciable degradation thereof.  The liner, after insertion into the pipe, may be saturated with a monomer such as methyl methacrylate and caused to swell into contact with the pipe the assembly then being irradiated to convert the monomer into polymer and render the swelling permanent and, simultaneously, cause adhesion of the liner to the pipe.  Alternatively, the assembled pipe and liner is heated to cause the liner to expand into contact with the pipe.  To reduce the diameter of the liner the latter may be suspended vertically while in a heated condition and extended by a weight, or drawn through a tapered die.  An irradiated tubular film may be forced by gas pressure against the internal surface of the pipe to form a primer coating and to facilitate bonding of the liner to the pipe.  According to the Provisional Specification, tubular or other members are in addition to lining thereof, covered with polyethylene applied in sheet form or by spraying, or deposited from solution; if the cover is in the form of a tube the latter is expanded by internal pressure, fitted over the pipe, and caused to contract by reheating.  Also, the die for reducing the diameter of the liner may be lined with polytetrafluoroethylene, the liner, after emergence from the die, being cooled by cold water spray or a forced air current.

Abstract: 726,897. Gas turbine plant. BRITISH THOMSON-HOUSTON CO., Ltd. May 14, 1952 [June 7, 1951; Feb. 21, 1952], Nos. 13531/51 and 4616/52. Class 110 (3). [Also in Group XII] Apparatus for generating combustion products under pressure, using a monofuel, i.e. a fuel which does not require external oxygen for decomposition, e.g. propyl nitrate for supply to a turbine-driven starter comprises an auxiliary reaction chamber provided with heating means for the initial decomposition of the monofuel which discharges into a main combustion chamber, also fed with the monofuel, through a discharge nozzle. The relative volumes of the auxiliary and main reaction chamber, and the relative areas of the discharge nozzle from the auxiliary chamber and outlet nozzle from the main chamber are so related that the initial decomposition of the monofuel in the auxiliary chamber is selfsustaining and the heated gaseous fluid entering the main chamber has such a temperature and pressure as to initiate a self-sustaining decomposition in the main chamber. In the arrangement shown an auxiliary reaction chamber B and a main reaction chamber A are arranged in series and fed with a monofuel through a conduit E and spray nozzles F, Fl. An electrically-heated coil G is arranged in the chamber B. On starting the nozzle F is shut off and fuel supplied through the nozzle F<SP>1</SP> to the chamber B where it is initially decomposed by the heater G. The gases from the chamber B enter the main chamber A through the pipe D. Fuel is now fed to the nozzles F and decomposed. The fuel nozzle F<SP>1</SP> and heater G may then be shut off. A modification in which an intermediate reaction chamber is placed between the main and auxiliary reaction cham- . bers is also described. In this arrangement the fuel supply to each chamber is controlled by a pressure operated switch responsive to the pressure in the preceding chamber.
