Abstract: 1,235,122. Fibrillating ribbons or tapes of synthetic polymers. IMPERIAL CHEMICAL INDUSTRIES Ltd. 30 July, 1969 [19 Aug., 1968], No. 39488/68. Heading B5B. [Also in Division D1] A longitudinally oriented fibrillatable ribbon or tape consisting of a synthetic organic polymeric material such as a polypropylene, a polyamide, a polyester or a mixture of any of these polymers, is fibrillated by subjecting the ribbon or tape while travelling under tension to the action of a series of at least two gaseous fluid false-twisting means such that the direction of twist imparted to the strand is completely reversed between adjacent false-twisting means. There may be no change in longitudinal direction of movement of the strand between the first and second or succeeding false-twisting means. The twist imparted by the first falsetwisting means may be allowed to run back over or into a hotplate or heating zone positioned before the false-twisting means. The material after passage through the false-twisting means may be allowed to relax at least partially and the relaxed material may be further heat treated. The ribbon or tape may be heated in the absence of twist before passing into the fluid falsetwisting means. The gaseous fluid in the falsetwisting means may be air or steam and a series of four fluid false-twisting means may be used, the direction of twist alternating throughout the series. Twist stopping guides may be positioned upstream and downstream of the fluid false-twisting means to confine the false twist effects within a shorter length. In an example, an undrawn tape consisting of a melt blend of 95À5% of polyhexamethylene adipamide and 4À5% of polypropylene and having a width of 9À5 mm. and a thickness of 0À055 mm. is drawn at a draw ratio of 5 and continuously fed at a speed of 18 metres per minute to a heating zone maintained at a temperature of 160 C. and then passed at a tension of 49 grams through two contra-rotating air vortices produced by a jet device (see Division D1) fed with air at a line pressure of 10À2 kg./cm.<SP>2</SP> gauge. The fibrillated tape thereby produced is wound up on a constant tension winder.

Abstract: 1,150,557. Treating wool. FISONS INDUSTRIAL CHEMICALS Ltd. 16 Sept., 1966 [17 Sept., 1965], No. 39714/65. Heading D1P. Wool is rendered shrink resistant and non- felting and may be cleaned and whitened by treating it with a solution comprising a chloro- or bromoamine and/or a chloro- or bromoamide and a chlorinated hydrocarbon solvent therefor and then treating it with a reducing agent dissolved in a chlorinated hydrocarbon solvent. Suitable chloro- or bromo-amines or -amides are N-chloro-p-toluene sulphonamide, N,N-dichloroacetamide, N-chlorophthalimide, N-chlorosulphamic acid, trichloroisocyanuric acid, dichloroisocyanuric acid and its salts, 1,3-dichloro-5,5-dimethyl hydantoin, tribromomelamine, N-bromosuccinimide, hexachloromelamine, tetrachloromelamine and trichloromelamine and suitable chlorinated hydrocarbon solvents are carbon tetrachloride, trichloroethylene and perchloroethylene and mixtures thereof. The solution may also contain a supplementary solvent, e.g. white spirit or glacial acetic acid. A supplementary solvent may be used to promote the miscibility of the chlorinated hydrocarbon with water which may also be present in the solution. The chlorine or bromine compound may be present in amounts sufficient to provide 1-5% by weight of active chlorine or bromine based on the weight of the wool treated and liquor ratios of 1:100 to 10:100 may be used. The treatment may be effected at a temperature of from ambient temperatures to just below the boiling point of the solvent or mixture of solvents, in batch operations the temperature being increased as the active chlorine content of the bath becomes exhausted. The process may be effected at a pH of 2-8.5, the solution optionally containing formic acid or pyridine and the pH of the bath being reduced by the addition of acid as the bath becomes exhausted. Prior to the treatment the wool may be passed through one or more vessels containing a chlorinated solvent or other solvent so that the wool is cleaned, oil being removed and/or through one or more vessels containing a chlorinated hydrocarbon solvent or other solvent and an acid or base. The wool may subsequently be rinsed by passage through one or more vessels containing a chlorinated solvent or other solvent and passed through one or more vessels containing a reducing agent dissolved in a chlorinated hydrocarbon solvent for dechlorinating or debrominating the wool, e.g. a mixture containing formic and/or acetic acid, a chlorinated hydrocarbon solvent and sulphur dioxide.

Abstract: 326,252. Associated Telephone &. Telegraph Co. Nov. 28, 1927, [Convention date]. Divide'd on 301,399. Drawings to Specification. Selective distant control and signalling systems. -Relates to a system for the selective operation of apparatus units, such as circuit breakers at a number of substations or signalling devices such as call bells of a train despatching system or the semaphores of a train signalling system. The substations are arranged in parallel across a pair of line wires and selection of any particular unit at a substation is effected by a three-train impulse code, the total number of impulses of the three impulse codes being fixed. The system described is identical with that described in Specification 301,399, but the claims relate to the step-by-step selective switches employed at the substations. Each switch is responsive to the three-train code, selection of any particular device at a substation being effected by the first and second trains of impulses, and operation of the selected device being effected at the termination of the last train which brings the switch into an off-normal position from which it is driven to normal in response to the transmission of a further impulse from the control station. The first train of impulses is also characteristic of the station at whch the device to be selected is located, the switches at the other stations being unresponsive to the second and third trains.

Abstract: 404,181. Momentary-contact switches. GLOSS, K. SCHAFFLER-, (trading as SCHAFFLER & CO.), 138, Lerchenfelderstrasse, Vienna. April 13, 1933, Nos. 11130 and 11131. Convention dates, May 30, 1932, and Aug. 10, 1932. [Class 38 (v).] A momentary-contact switch for a mine firing-apparatus comprises a handle 1 connected to a driving spindle 3 carrying a gear sector 2 which has a depending fork 35 carrying a pivoted pawl 5. A lever 6 pivoted at 31 is urged in a clockwise direction by a leaf spring 7 and carries a curved cam projection 30 and a pivoted pawl 8. When the handle is turned in a clockwise direction, the pawl 5 slides along the inner curved surface of the cam 30 and turns the arm 6 in an anti-clockwise direction. During this movement the pawl 8 slides idly along a curved surface of a slide 9 and finally rests against its flat end surface, as shown in Fig. 3. On turning the handle 1 further until the gear sector 2 engages a stop 13, the pawl 5 slips off the end of the cam 30 and the lever 6 returns due to the spring 7 causing the pawl 8 to wipe along the end surface of the slide 9 until it stops clear. During this action, the slide 9 moves against the action of a spring 12 causing a contact 10 to move between contact springs 11. The slide 9 then moves back again and the circuit 34 is thus completed momentarily. When the handle 1 is released it is returned by a spring 4, the pawl 5 riding idly along the outer curved surface of the cam 30. A revolving mass 15 is geared to the slide 9 to control the time during which contact is made. The gear sector 2 is geared to a magneto to provide the ignition current. In a modification using a battery to provide the current the gear sector is dispensed with and means are provided for latching the switch unless the battery has sufficient voltage for energizing an electromagnet to withdraw a pair of latches.
