Patent GB-481440-A (GB)
Title: Treatment of fibrous material of vegetable and mineral origin
IPC: D01C3/00
Filed: 1936-09-08
Abstract: The spinning of vegetable, artificial and mineral fibres is facilitated by treating the fibres with a solution of sericine. For the treatment there is used a solution of sericine in an alkali, preferably a soap, conveniently boiled-off liquor; and to the solution an alkali sulphocyanide may be added, and also a substance such as Irish moss in the case of slippery fibres such as kapok.  The alkali sulphocyanide may be applied as a separate treatment.  An addition of formaldehyde may be added to the last bath.  After treatment, the fibres are dried.  Fibres so coated and weighted do not exhibit electrical effects, and they are free from "fly" in spinning and from "shedding" when spun. Specification 481,441 is referred to.

Abstract: 1,009,859. Rolling. UNITED ENGINEER. ING & FOUNDRY CO. June 26, 1962 [Oct- 20, 1961], No. 24484/62. Heading B3M. [Also in Division F2] A rolling mill is adapted to house one of a number of pairs of rolls of different lengths, the chock assemblies of the rolls being engageable by beams extending through the windows of the mill frames. Work rolls 22 and 23, Fig. 1, are mounted in chocks 17 and 18, the lower chocks resting on a beam 25 while the upper chocks are urged upwardly against a beam 24 by the arms 48 of a fluid pressure balancing mechanism 46. The beams support the chocks of rolls of differing lengths and allow axial movement of the chocks. Motor driven pairs of screws 35 and 37 act on the beams and serve to adjust the roll spacing. To change the rolls the upper beam 24 is raised by screws 37 until fluid pressure operated latches 59, Fig. 2, are moved inwardly to support the beam, and both sets of chocks are slid axially along the beams, projections 27 of the beam 25 engaging recesses in the upper chocks to support the roll 22. Laterally adjustable idle vertical rolls 77 and 78 are provided, and the couplings 63 and 64 for driving the work rolls are axially adjustable by a motordriven screw and provided with a balancing mechanism. A chock 17, Fig. 3, in plan, is secured by a screw 103 to a fixed yoke 105 extending across a housing window. For larger rolls a U-shaped yoke is employed, projections 111 of the chock being guided in the yoke to prevent rotation of the chock. Fluid pressure pistons 112 give axial adjustment of the roll after loosening nuts 107 and 108. Bars 96 extend from the adjustable chock 17 to a freely mounted chock 18, extensions of these bars forming exit and entry guides (Fig. 9, not shown). A thrust bearing 86 is provided with blocks 92 and 95 and an adjustable wedge 93 such that slight vertical movement of the bearing takes place when the babitt bearing 19 wears, vertical forces on the thrust bearing thus being avoided.

Patent GB-481515-A (GB)
Title: Production of organic halogen compounds
IPC: D01F6/08
Filed: 1936-09-11
Abstract: Normally solid ethylene polymers which may have a small oxygen content, obtainable by the process described in Specification 471,590, are subjected to the action of one or more halogens or halogen compounds capable of introducing halogen, e.g. iodine chloride, if desired in the presence of halogen carriers such as iodine, and aluminium or ferric halides.  The reaction may be effected with a solution or suspension of the polymer in, e.g. acetic acid or carbon tetrachloride, at room temperature or above, e.g. above 50 DEG  C., or with the polymer in the molten state.  The polymer becomes more rubbery until about 30 per cent of chlorine or 60 per cent of bromine has been introduced, further halogenation resulting in the products becoming harder, more brittle, and less soluble.  The products can be separated into fractions by extraction with solvents or precipitation from solutions.  They are used for forming films, tapes or thread, for coating or impregnating materials such as paper and fabric, and for electrical insulation.  Examples describe the chlorination or bromination of polymers of varying molecular weight in suspension or solution in carbon tetrachloride or acetic acid at various temperatures up to 100 DEG  C. and for different times, yielding products containing up to 53,5 per cent chlorine or 71 per cent bromine.  This last product is separated by fractional precipitation with alcohol from a benzene solution giving fractions containing 55,3, 71,5 and 86,0 per cent bromine.

The expander 11 has a central threaded portion 12 to engage the lower end of the draw bolt 13 and a pair of wings 14 which lie within notches 9 in the clamping member 8. The angle of the notches 9 and the wedges 14 is such that the clamping member 8 is self-locking and will not loosen relative to the steering tube 1 unless the expander 11 is forceably driven downwards. The upper end of the bolt 13 has a threaded portion 16 engaged by a screw-threaded nut 17 in the form of a wheel. When it is desired to turn the handlebars from their normal position to a position in which they lie fore-and-aft of the bicycle to facilitate parking and storage, the nut 17 is unscrewed to give some longitudinal play between the clamping member 8 and the bracket member 3. The member 3 and the handlebars 7 may then be rotated through 90 degrees. An opposite rotation of the nut 17 will again draw the bracket member 3 downwards and lock the dogs 10, 20 in alternative operative positions, The nut. may then be locked by a padlock or other detent. In a modification shown in Figure 3, the wheel 17 is replaced by a cam lever 24 pivotally mounted on the upper end of a squared part 23 of a member 22 which is connected by a swivel coupling 21 to the bolt 13. The cam surface 25 engages a washer 26 which bears on the upper surface of the bracket member 3 through a helical spring 27. A bracket 29 passes through a slot in the cam lever 24 and is apertured to receive a padlock or other locking device.
