Title: Spontaneously crimping composite filaments and yarns
IPC: D01D5/30
Filed: 1965-11-24
Abstract: The process of Specification 979083 (wherein spontaneously crimping polyolefine filaments are produced by stretching to at least 1.5 times their original length composite filaments composed of two different mutually adherent polyolefine components side by side along the length of the filaments, the two components differing in their inherent viscosities by at least 0.1) is modified in that the bi-component filaments are tri-lobal filaments formed by melt-spinning the two components through three-armed spinneret orifices, i.e. orifices consisting of three slots radiating from a common centre and communicating with one another at that centre.  The centres of the orifices may be vertically below the straight edge along which the two components unite, the slots of the orifices and the angles included therebetween being arranged symmetrically about said edge as a line of symmetry.  Cooling air may be blown in to the composite filaments from a direction faced by one of the slots of each orifice, the component of lower viscosity flowing through this slot, which may be of different length from the other two slots, these being equal lengths.  The stretched filaments may be allowed to crimp by release of tension.  The crimpled filaments may be heatset in the slack state.  The crimp effect of the filament is three dimensional, disappears when the filament is subjected to high tension, but reappears spontaneously when the tension is discontinued.  The filaments are stapled and spun into yarn.

Abstract: 1,106,379. Electromagnetic relays; turret machines for assembling contact devices. WESTERN ELECTRIC CO. Inc. 16 Dec., 1964 [20 Dec., 1963], No. 51130/64. Headings H1J and H1N. [Also in Division H1] Magnetic reed contacts are sealed into a glass sleeve supplied with protective gas (nitrogen and hydrogen mixture) under pressure, e.g. 27 p.s.i., whilst enclosed in a chamber filled with air at a lower pressure, e.g. 20 p.s.i. Each chamber comprises a base 27 and a hood 140 which may be sealingly secured thereto, mounted on a turret intermittently movable past a feeding station 25. As the chamber approaches the feeding station 25 the hood is removed by a cam-controlled rod (144), Fig. 2 (not shown). The completed contact device is ejected, the air and gas supplies are cut off, carriages 45 and 85 are moved apart under the control of a camactuated rod 122 and jaws 48, 94 carried by the carriages are opened. At the feeding station 25 a glass sleeve 15 is inserted into heating coils 41, 42, through openings in polepieces 36, 37 of electromagnet 35 where it is held by a blade spring chuck 38. At the same time magnetic members 63, 99 feed upper and lower magnetic reeds 19, 20 between the open jaws 48, 94 and actuators 61, 98 move cams 53, 96 carried by carriages 45, 86 respectively to the left to close the jaws. When the chamber leaves the feeding station, the hood is closed and sealed to the base. Filtered air is then introduced to the chamber and protective gas is directed into the sleeve 15 by a nozzle 102. The reeds 19, 20 and sleeve 15 are initially vertically aligned but during movement of the carriages 45, 85 towards a locating stop 81 the lower reed 20 is offset from the upper reed 19 by the engagement of a roller 106 carried by a laterally movable part 91 of the carriage 85 with a cam surface 108 of a control member 75. When the reeds overlap the control member 75 moves down so that roller 106 engages a cam surface 109 and moves the part 91 to the right so that reed 20 engages reed 19. The electromagnet is energized causing the reeds to attract and the jaws 48 are partially opened by the cam 53 being moved to the left by a twoarmed lever 68 actuated by continued downward movement of control member 75. Whilst the upper reed is held solely by magnetic attraction the upper seal is formed thus ensuring that the contact surfaces are aligned. On completion of the upper seal, the electromagnet 35 is de-energized and the lower reed 19 is moved a predetermined distance to the left to set the gap, by engagement of roller 106 with an adjustable surface 110 of control member 75. Finally the lower seal is formed.

Title: Improvements in or relating to machines for producing articles by injection-moulding
IPC: B29C45/67
Filed: 1966-11-17
Abstract: 1,150,116. Injection moulding machines. DESMA-WERKE G.m.b.H. 17 Nov., 1966 [18 Dec., 1965], No. 51461/66. Heading B5A. The invention relates to an injection moulding machine for producing footwear &c. of rubber, plastics &c. and comprising a turntable (10), Fig. 1 (not shown), carrying a plurality of moulds 11 each including a core (16), and two lateral parts 13, 14 and a cover 15 articulatedly connected together. According to the invention the moulds are clamped at an injection station by means of two frames 17 in the interior of which are hydraulic pressure devices 18, 18C for applying pressure to the parts 13, 14 and cover 15 respectively. The frames 17 have ball-joint mountings 21 and are reciprocated vertically by hydraulic cylinders 20, 20d. Fig. 7 (not shown) shows a circuit for operating the cylinders 20, 20d, including a pressure source (23), slide valve (33) and pressure limiting valve (25) and means for compensating leakage. Pressure source (23) also supplies fluid for the high pressure devices 18, 18C. Each device 18 comprises a booster 35 (see Fig. 6, not shown) associated with a plurality of rams 37 arranged in a common housing 36 (Fig. 5). The booster 35 is controlled by a non-return valve (38) which can be released by a piston drive (39). Initially low pressure oil opens valve (38) and passes to the rams 37 which advance to abut the mould parts. A piston (47) of the booster 35 is simultaneously moved to the right in Fig. 6 (not shown). By appropriate setting of valves (40, 43) a piston (48) of the booster 35 is charged by the source (23) to cause high pressure mould locking by the rams 37. Each ram 37 comprises a piston 52 having a pressure head 58 loosely retained on a spherical surface of the piston 52 by a bolt 59. The piston 52 is advanced against the action of a spring 55 and is prevented from over advancing by a safety valve 54. A pressure plate 62 for engaging the mould cover 15 is slidably and tiltably mounted to accommodate deviations from an exactly normal mould position. Thus the plate 62 which has an opening 61 for an injection head (12d) is displaceably held on a mounting block 70 by means of a guide rod 77 and three pairs of rollers 73, 74, 75 (Fig. 3). The mounting block 70 is itself mounted on a swivel bolt 69 and held in a mean position by oppositely acting springs 66, 67 (Fig. 4). When the clamping frames are moved towards each other the pressure plate 62 is moved towards the cover 15 by the engagement of rollers 63 with rails 65 on the plate 62 (Fig. 2).
