Title: Improvements in or relating to the manufacture of leather-like material
Inventor: FAIRCLOUGH JOHN HOLDEN
IPC: D04H1/4334
Filed: 1958-04-16
Abstract: 910,483. Leather-like material. LANTOR Ltd. April 8, 1959 [April 16, 1958], No. 12108/58. Class 140. A method of manufacturing a leather-like material comprises pressing a web of fibres having a substantially random orientation and bonded together with a quantity of a polymeric thermoplastic fibre-bonding agent which softens at a temperature less than the temperature at which the fibres of the web would be damaged and simultaneously applying heat to one side only of the web sufficient to cause the bonding agent to soften only on that side so as to form a material which has a greater density on that side than on the other side and which retains the density difference when removed from the heat and pressure, the quantity of bonding agent being such that the web so formed contains not less than 40% and not more than 75% calculated on the total weight of the dry bonded web, of bonding agent. Specified fibres are cotton, polyester, nylon, and viscose rayon. Specified bonding agents, are natural rubber, polyvinyl chloride latex, vinylidcne polymers or copolymers, copolymers of acrylonitrile and butadiene, copolymers such as butadiene/ styrene, butadiene 1 -3/acrylonitrile, vinyl chloride/vinyl acetate, vinylidene chloride/vinyl acetate, vinyl chloride/vinyl acetate/acrylonitrile, ethylene/vinyl chloride, butadiene/ methyl methacrylate, butadiene/acrylonitrile, isoprene/acrylonitrile. The steps of impregnating and drying, whereby the bonded web is formed, may be carried out separately from the step of hot-pressing, whereby the product of the invention is formed. Hot-pressing may be carried out between plating, one of which is heated and the other unheated or between a pair of rollers, one of which is of metal and heated and the other of compressed cotton and unheated. Specification 659,088 is referred to.

Filed: 1941-09-19
Abstract: Ethylene, alone or mixed with other polymerizable compounds, is polymerized at elevated temperature and pressure, in an aqueous medium and a polymerization catalyst, but in the absence of a dispersing agent.  The aqueous medium may contain volatile organic liquid, e.g. iso-octane, toluene, butyl acetate, ethyl ether, n-hexane, cyclohexane, cyclohexanol, methanol, ethanol, butanol, metabromtoluene or petroleum ether.  Small amounts of organic per-compounds may be used as catalyst, preferably in a pH range of 1-6; or metal persulphates with a pH 7-11, as described in Specification 579,881, may be employed.  The process may be carried out as a batch process, or continuously, e.g. in the manner described in Specification 579,882.  Other polymerizable compounds are specified.  Examples are given of the production of polymers from ethylene and propylene and of copolymers of ethylene with methyl methacrylate and vinyl chloride.

Title: Improvements in synthetic monofils for use as bristle material
IPC: D01F6/62
Filed: 1950-05-16
Abstract: Polyethylene terephthalate monofils for use as bristles are given an improved flexibility, strength, curl-resistance and recovery from bending, by drawing them at 55-180 DEG  C. to a total draw ratio of 4.6 : 1 to 5.2 : 1, then heating to effect a reduction in length of 5 per cent to 10 per cent and finally heating at 150-250 DEG  C. while they are held to prevent shrinkage. The polyester preferably has an intrinsic viscosity (as defined) of at least 0.35.  The drawing operation may be effected in two stages, the first being effected at 55-80 DEG  C., and the second at 80-180 DEG  C.  Examples describe the two-stage drawing operation followed by heating in steam at 100 DEG  C. to effect the shrinkage and then, while reeled to prevent shrinkage, by heating in mineral oil or air at 180 DEG  or 190 DEG C.

Abstract: 1,069,783. Deforming helical coils; shearing. WOODFIELD ENGINEERING CO. Ltd. March 26, 1964 [March 28, 1963], No. 12269/63. Headings B3E and B3W. Spring clenching apparatus 13 comprises a spindle 15 arranged to receive at one end a removable, axially projecting element 17 and a head 18 adapted to be secured on the spindle to lock the element against axial movement relative thereto, the element projecting through the head so as to co-operate with a projection 21 on the head during rotary movement thereof to clench a spring. The spindle 15 is rotated by a pinion 23 and a reciprocating rack and is biased in a lower position by a spring 25, a pneumatic cylinder means 27 serving to lift the spindle into the operative position. A combined cutting and clenching unit (14), Fig. 4 (not shown), is similar in construction to the clenching unit but the spindle thereof is maintained in its upper operative position by adjustable screw means (28), and the projection (21) is provided with cutting edges which co-operate with a fixed cutter (29). In operation a helically coiled lacing spring 10 is fed through a helically grooved guide (9), and between the pin (17) and projection (21) of the unit (14) before passing through a number of hour-glass shaped springs to lace them together and between the pin and projection of the unit 13 which is in its raised position. The leading end of the spring then trips a pivoted lever 11 to operate a microswitch which actuates the pneumaticallyoperated racks of both devices to rotate the spindle 15 of the device 13 which causes the projection 21 to bend the free end of the spring about the pin 17 against a fixed jaw whilst the projection (21) on the spindle of the device 14 severs the spring and forms the severed end about the other pin (17). The rack trips a micro-switch to effect retraction of the clenching unit 13 spindle and the reverse rotation of both spindles.

Abstract: 921,164. Automatic control. MOTOROLA Inc. April 7, 1960 [May 1, 1959], No. 12421/60 Class 38 (4). A pressure-responsive device operates an electrical transducer through a friction clutch which is held engaged by a permanent magnet but slips when the output member of the clutch engages a limit stop. In Fig. 5 the cranked links shown are attached to pressure-responsive capsules (not shown) on an aircraft so that a shaft 46 is rotated in response to altitude changes. A permanent magnet 72 secured to shaft 46 draws a sleeve 80, otherwise free to rotate on shaft 46, into engagement with a friction disc 74 adjustably secured to shaft 46. An armature 70 which is associated with an E-type pick-off (not shown) is coupled to sleeve 80 so that electrical signals dependent in magnitude and sense on altitude changes are produced by the pick-off. These signals are utilized to maintain altitude constant by controlling the pitch channel of the aircraft's automatic pilot (not shown). The magnitude of the signals is limited by adjustable stops 84, 86 and slip between discs 74, 80 when the limits are reached permits the automatic control to be over-ridden manually to set a new altitude to be maintained.

Lamps forming line of light.-In a tubular electric lamp fitting, as claimed in the parent Specification, the rods 1, 2 of the frame are insulated with sleeves 5, 6 of vulcanized fibre, &c., and hold the reflector in position between them. In one form, the substantally parabolic reflector 7, Figs. 1 and 3, made of resilient material such as aluminium, is formed with external projections 8, which engage the frame rods 1, 2. The rods 1, 2 pass through bridge-piece 3, 4 into recesses in which the ends of the sections of the insulating- sleeve 5, 6 fit tightly. Each bridge-piece supports a contact-element comprising a plunger 10 and a sleeve 9, which is connected within the bridge-piece to one or other of the frame rods by a resilient metal wire 11 with looped ends, the wire lying in a slot or saw-cut 12 in the bridgepiece. Clips 13 are attached to the outer face of the bridge-piece to secure the fitting in position, and insulated terminal connection plugs 20 are fitted on the frame rods 1, 2. A pair of the lamp fittings 3 may be fixedly connected together in various arrangements by means of strips, or two or more fittings 3 may be adjustably combined by pivoted links or the like. In another form of fitting, the rods 1, 2, Fig. 6, are arranged close together and to the rear of the lamp, and the reflector 7 is supported by spring clips 17 engaging the end-caps of the lamp and is secured in position by tabs 19 which project between the frame rods 1, 2. In another arrangement, the reflector may be adjustably secured by a pair of clips, one at each end of the reflector, to the opposing surfaces of the bridge-pieces 3, 4. A plurality of lamps may be employed, arranged either side by side or end to end. The Provisional Specification also states that the opposite sides of the reflector may be cut or slotted to form supporting-tongues which are bent outwards to engage with the frame rods.
