Title: Improvements in textile yarns and fabrics
IPC: F41H3/02
Filed: 1954-07-15
Abstract: 788,291. Yarns and threads. THIER. A. N. DE. July 7, 1955 [July 15, 1954], No. 20641/54. Class 120(3) A yarn comprises a mixture of natural, synthetic, or artificial fibres which respectively are of the primary colours of the solar spectrum i.e. red, yellow and blue or red, green and blue, and are present throughout the yarn in proportions such as to give an infra-red radiation reflectance approximating to that of white when measured by infra-red photography. Coloured filaments may be extruded from separately dyed batches of artificial e.g. viscose, or synthetic fibre-forming material, cut into staple length, and the three batches of fibres are mixed in the required proportions and spun into yarn. Alternatively, batches of uncoloured loose fibres may be dyed in the respective colours, mixed, and spun. The yarn may comprise mixtures of different materials, e.g. cotton and rayon, or wool and rayon, and white fibres may be added.

Title: Improvements relating to the production of crimped yarn of continuous filaments of synthetic linear polymers
IPC: D02G1/02
Filed: 1957-07-01
Abstract: 815,202. Crimping yarns. INVENTA AKTIENGESELLSCHAFT FUR FORSCHUNG UND PATENTVERWERTUNG. July 1, 1957 [Aug. 4, 1956], No. 20705/57. Class 120(3) In the production of crimped yarn, a bundle of untwisted parallel or pretwisted smooth synthetic linear polyamide filaments is simultaneously stretched by at least 150 per cent and given a false twist of 2000-3500 turns per metre and is heat-set in such twisted condition. Crimp yarn having extensibility of about 100 per cent may be produced from unwashed and unstretched filaments on spinning spools; yarn with higher extensibility may be produced from filaments pretreated by twisting e.g. to 400 turns per metre, washing at about 50‹C. and drying, optionally under tension, to set such twist. The crimp set in the yarn may be increased if the yarn is twisted before it is finally fixed e.g. immediately after crimping. As shown, freshly spun filaments 1, which may have a slight twist, are withdrawn from a spool 2 through a tension regulator 3, feed rollers 4, around a braking or snubbing pin 5 which also acts as a twist stop, through a tubular heater 6 and a false-twister 7, over a guide 10 acting as a twist stop, then between rollers 8 rotating at a higher peripheral speed than the rollers 4 to effect the stretch and the resulting yarn is wound on a reel 9, then washed, on perforated spools, or in a loose skein, to fix the crimp. Specification 397,046 is referred to.

Title: Improvements in engine starters
IPC: F02N99/00
Filed: 1925-08-12
Abstract: 262,679. Rogers, F. H., (Eclipse Machine Co.). Aug. 12, 1925. Turning-gear.-An engine starter includes an inertia, device, such as a fly-wheel, connected through reduction gearing to a driving member 11 which is moved automatically into engagement with an engine member 12 when a certain speed of rotation is attained by the inertia device. As shown, a bevel gear 16 forming part of the reduction gearing is engaged by a pinion on the shaft of the fly-wheel (not shown) and by a pinion 40 on the shaft of an electric motor 38 serving to set the fly-wheel in rotation. The gear 16 rotates about a shaft 19 and carries planet pinions having teeth 25 in mesh with a fixed gear 31 and teeth 24 in mesh with a gear 15 on the shaft 19. A rotatable barrel 3 secured to the gear 15 is connected by a multi-plate clutch 5 to a shell 4, a threaded part 10 of which engages threads on the driving member 11. A shaft 57 forming an extension of the member 11 is acted upon by a solenoid 59 in series with the motor 38, so that the member 11 is held out of engagement with the engine member 12 until the motor attains a. certain speed and the current in the motor and solenoid is correspondingly weakened. To ensure axial movement of the member 11 when released by the solenoid 59, a second solenoid 60 in parallel with the motor acts on discs 72, 73 in frictional engagement with a disc 74 having a central bore splined on the shaft 57. A switch 62 connects the motor and the solenoids to the battery 61.

Title: Improvements in and relating to time delay circuits
IPC: H01H47/18
Filed: 1937-07-28
Abstract: 495,133. Electromagnetic relays ; automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. July 28, 1937, No. 20914. Convention date, July 28, 1936. [Class 38 (v)] [Also in Group XXXV] In a time delay relay applicable for use with a voltage regulator, a saturable core reactor 23 has two windings, one winding 25 being energized by alternating current and the other winding 28 by the same current after it has been rectified by a rectifier 26, the rectified current serving gradually to saturate the core and thereby reduce its reactance so that eventually sufficient current passes to operate the relay 19 itself. The invention is shown applied to a voltage regulating system. Variation of the output voltage 4 causes a corresponding variation in a winding 10 which causes a relay 9 to engage an upper or lower contact and so energize a coil 11 or 12 thereby closing contacts 13, 20 or 15, 21. Contacts 13 or 15 prepare a circuit at 14 or 16 to one of two windings of a reversible motor 8, but the circuit is only completed and the motor driven to operate a tap changing switch 7 controlling the voltage when contacts 18 leading to a common point 17 are closed by energization of the relay 19. The relay 19 responds only after a time interval following the closing of the contacts 20 or 21. Closure of contacts 20 or 21 causes the energization of a relay 22 which closes contacts 24, 27. A circuit is then completed through windings 25, 28 and rectifier 26 till, after say 10 seconds, the core is sufficiently saturated to allow sufficient current to pass to operate the relay 19. Adjustable resistances 29, 30 are inserted as shown to regulate the time interval and to provide that an excessively high voltage will cause an instantaneous response and an excessively low voltage will delay the response indefinitely.

Addition to 263,830, [Class 55 (ii), Gas manufacture &c.]. [Class 55 (ii).] The method of removing gaseous impurities such as carbon dioxide and sulphuretted hydrogen from combustible gas according to the parent Specification is modified by utilizing the pressure of the gases evolved during regeneration of the washing fluid to force the latter into the recovery tower, wherein it is subjected to air blast treatment. The gas at high pressure is washed with cold water in a scrubber 2 containing screens, rings, &c. The water issues from the scrubber through a pipe 7 and is caused to rotate a Pelton wheel or turbine 6 before discharging into a tank 8. The gases which evolve owing to the fall of pressure, escape to the atmosphere through pipe 9. By closing a valve 9a, a high pressure may be obtained in the tank 8 sufficient to force the washing liquor through pipe 12 to the top of the recovery tower 13. The disengaged gases escape through an eliminating pipe mounted on this column.

Title: Improvements in apparatus for making glass cylinders
IPC: C03B15/14
Filed: 1919-09-03
Abstract: 154,354. Marks, E. C. R., (Universal Glass Co.). Sept. 3, 1919. Drawing.-Relates to drawing glass cylinders. The cylinder C is drawn from a tank 3 through a protecting-ring 5 by a bait 16, which is hung from an arm 14 adapted to swing horizontally, as shown by dotted lines in Fig. 1, to facilitate the removal of the finished article. The arm 14 is swung by a rope 53 which also operates a locking-bar 46 for securing the bar 14 in the correct position for drawing and taking-down respectively. At the end of the draw, the ring 5 is raised, so as to allow the heat of the tank 3 to melt off the end of the cylinder. Blowing air is supplied from a tank 18 where it is heated by a burner 20. The arm 14 is mounted on a hydraulic piston-rod 23, Fig. 5, the piston 24 having water above and below it. To raise the bait, compressed air is admitted above the water in the tank 27 to force the water into the cylinder 22. As the piston 24 rises, water passes from the space 31 through a partly closed valve 40 into a cylinder 33, causing a piston 34 to rise and, by means of levers 36, 38, 39, to open the valve 40 gradually, thus opposing less resistance to the rise of the piston 24 to compensate for the increasing weight of the glass cylinder being drawn. In a modification, Fig. 9, the bait-lifting piston 62 is pneumatically operated. Compressed air from a pipe 58 enters a chamber 56, where it is electrically heated, and passes into the cylinder 61, from which some of it passes, by way of the hollow piston rod 63 and a flexible, pipe, into the glass cylinder being drawn.
