Abstract: 1448302 Crimping yarns NATIONAL SPINNING CO INC 23 April 1974 [10 May 1973] 17788/74 Heading D1F [Also in Division B8] To make bulked yarn, a continuous filament synthetic yarn having pre-exsistent latent crimp characteristics has imparted to it a twist between 2.5 and 4.5 t.p.i., the twisted yarn is passed through a first treatment zone to develop the crimp characteristics and render them manifest, the yarn is removed from the zone under minimum tension and is immediately relieved of the tension, the yarn is deposited as a uniform, uncompacted mass in a container, and the yarn in the container is treated in a second zone to set the manifest crimp. Two yarns, e.g. of nylon, each with a given twist are plied with the given twist but in the opposite direction. Plied yarn 10, Fig. 1, is wound on rotating mandrel 18 by flier 19. The mandrel comprises converging conveyor belts 20, e.g. four of six belts, whose travelling outer surfaces carry spaced yarn windings along the mandrel. The windings supported slackly on the taping mandrel are treated by heated, moistened air (e.g. at 180‹-190‹F dry bulb, 170‹ wet bulb) circulated in chambers 21, 23 to develop latent crimp properties. The windings are partially dried by an air current in chamber 25. The yarn is drawn over end from the mandrel by rolls 32, 33 and deposited in rotating container 34. The yarn passes through guide 27, and is traversed longitudinally of the rolls, and radially between the centre and the circumference of the container, by guide 28. The full container is autoclaved at 240-270‹F in saturated steam. Two ends of plied yarn may be treated on the mandrel simultaneously, the withdrawn ends being deposited in side-by-side containers, Fig. 2. Rolls 30, 32 may be rubber covered, or roll 32 rubber covered and roll 30 provided with a serrated steel surface.
Patent GB-595983-A (GB)
Title: Improvements in the production of pattern effects on textile fabrics
IPC: D06Q1/08
Filed: 1945-07-12
Abstract: A patterned or delustred fabric is obtained by wetting a fabric made of or containing yarns of a thermoplastic organic material with a liquid medium having a softening or swelling action on the material and subjecting the wetted fabric in swollen condition to pressure between a pair of unheated, rotating, cylindrical surfaces, one of which is smooth and the other of which is engraved in a pattern or covered with a web of textured material. p  The pattern on one of the cylindrical surfaces may be engraved in intaglio fashion.  The fabric becomes locally delustred on the surface at those areas within the borders of the engraved design where the rollers exert less pressure. As softening or swelling agent there may be used ethyl, propyl, butyl, or other lower aliphatic alcohol, or acetic, propionic, or other aliphatic acid, or acetone, methyl ethyl ketone, or other ketone, or a halogen hydrocarbon such as chloroform, or phenol, cresols, o-toluidine or benzidine.  The swelling agent may be used in solution in water or an inert organic liquid having no swelling or solvent action on the substance of the fabric.  The thermoplastic substance may be cellulose acetate or other cellulose ester or ether, or a synthetic linear polyamide (nylon), or a polyvinyl compound. Dyestuffs may be included in the treating liquid.  An overall effect may be obtained by subjecting the fabric to pressure between a smooth roller and a textured fabric or other such web of textured material, carried by one of the rollers.  After passing through the rollers, the fabric is passed through water or other liquid which washes out the swelling or softening agent.

Filed: 1944-09-19
Abstract: 598,233. Quick-action switches. MACRAE, R. S. Sept. 19, 1944, No. 17909. [Class 38(v)] [Also in Group XXI] An electric switch comprises a spring- operated contact-member 13 held in the open position by a release member 6 held in engagement with the member 13 by pressure which if released or increased releases this member. The member 13 carries a coned flange 14a engaged by the coned end 19 of the member 6 which is held in open position by a safety pin 8 passing through it and the boss 3 in which it is mounted. This pin is withdrawn when the pressure of some object is applied to the head 7 for instance when used as a booby trap bomb release. If considerable pressure is applied to the head 7 a reduced frangible part 15 of the member 13 breaks and the striker is released. The member 13 may be released by a trip wire connected to the pin 8. A safety spring strip 24 inserted in a slot in the casing prevents the member 13 operating if prematurely released, an aperture in this strip receives the point 14 of the member 13 so that this member must be released before the strip can be withdrawn. Fig. 1 shows the switch in use as a firing device for a detonator 21 but when used as a switch the holder 20 for the detonator is provided with an insulated head 33, Fig. 6, which the member 13 is adapted to engage and a lead 32 soldered to the earthed holder. A telescopically adjustable screwed rod may be screwed into a tapped hole 29 in the head 1 in order that pressure may be transmitted to this head from a distance.

Abstract: 1,206,864. Moulding foamed thermoplastics. B. I. BARTNER. 18 April, 1968 [18 April, 1967], No. 18473/68. Heading B5A. [Also in Division B6] An article comprising an elongated core 12, Fig. 5, such as a pencil lead, a crayon, or a ballpoint-pen refill, and an outer casing 14, has the casing formed with a lining of thermoplastic material, the core being inserted whilst the lining is in a plastic condition, so that when the plastic sets, the core and casing are bonded together. The lining is of foamed plastic material and is provided with a rigid outer covering of non-foamed plastic. The casings 14 are formed by extruding thermoplastic material 22 containing a suitable foaming agent through an outlet 24. Surrounding the outlet 24 is a chamber 28 to which non-foamed plastic material 30 is fed to form the rigid outer covering. The chamber 28 may have ribs extending across it to form ribs on the outside of the casing instead of a continuous outer covering. Subsequently, the extruded material passes through a cooling bath 36, and transporting means 38, and is severed by a cutter 40 into lengths. An axial hole is now formed in each casing 14 by means of a heated probe 42, or, if such a hole is formed during extrusion, the probe enlarges the hole. The probe also melts the surface of the hole, and as the probe is withdrawn a pencil lead 12 is pushed into the casing from the opposite end. If the lead 12 is preheated, it can be used to form the hole, thus dispensing with the probe. Polystyrene, polypropylene, polyvinyl chloride or polyethylene of suitable density may be the plastic employed. The structure of the foamed plastic material is similar to that of wood so that a conventional pencil sharpener may be used. The probe 42, Fig. 4, comprises a nichrome wire 44 within a suitable casing 46 with an end 48 of the wire exposed and electrically joined as by silver solder to an outer stainless steel casing 52. The casing 52 and wire 44 are connected to a power source 56.
