Title: Improvements in the manufacture of staple fibres
IPC: D01D10/04
Filed: 1935-07-03
Abstract: Staple fibre from viscose is obtained by a continuous operation wherein filaments from a large number of spinning nozzles are combined to form a thick bundle and led vertically upwards and downwards a number of times over a series of rolls or similar deviating members, the thick bundle while travelling upwards being freed from tension, washed and, if desired, desulphurized, bleached, and again washed, the treatment liquid flowing in counter current, and the bundle is then passed to drying devices such as heated rollers, and to cutting devices.  The filament bundle may be treated with dilute ammonia or soda solution during the first washing process so as to neutralize acids.  In order to free the bundle from tension during the liquid treatment, the rollers may be rotated at different speeds or brake rods or plates may be provided.  The filament bundle may be cut to staple fibre while still containing a considerable amount of moisture.  The bundle may be curled by passing it while damp between grooved drying plates or rods arranged in the form of a grid.  The plates may be heated electrically, by gas flames, or by heated air.  They may be on endless bands and moved in the direction of the filaments.  As shown in Fig. 2, a large number of filaments 5 are combined together by rollers 17 and guides 18 to form a thick bundle 21 which passes up and down between rollers 22-37.  The upper rollers are driven at a lower peripheral speed than the lower rollers so that the filaments are free from tension during the upward run, and under tension when moving downwards.  Washing liquid is applied to the upwardly moving filaments from spraying nozzles 24, 38, 39, 40.  Dilute soda solution is applied from the nozzles 41, and water from nozzle 42.  The filament bundle passes to a drying drum 44 and then <PICT:0443076/IV/1> <PICT:0443076/IV/2> <PICT:0443076/IV/3> cutting device 51.

Title: Improvements in and relating to the continuous casting of metals
Inventor: LITTLEWOOD GEOFFREY
IPC: B22D11/053
Filed: 1958-06-17
Abstract: 849,418. Continuous - - casting machines. BRITISH IRON & STEEL RESEARCH ASSOCIATION, and MORTON, J. S. June 17, 1959 [June 17, 1958; July 31, 1958], Nos. 19333/58 and 24690/58. Class 83 (1). A continuous-casting mould is coupled to a fluid-operated device arranged to cause lengthwise movement of the mould, and there are means for controlling the supply of fluid to the device, and thus the mould movement, to release or prevent adherence of the ingot to the mould. The control means may be such as to cause movement of the mould when the ingot adheres to it, or to reciprocate the mould at regular intervals. In one embodiment, (see the drawing accompanying Provisional Specification 19333/58, the mould 13 is carried by a table 14 which is supported by pistons 16 with springs 18 below. Liquid may be pumped to the top of the piston 16. In operation, sticking of the ingot 12 to the mould 13 draws the mould downwards against springs 18, the movement causing a microswitch 28 to close a valve 25 in the liquid-supply system and cause a pressure build-up above the piston 16, which then moves down against spring 18 at a speed greater than that of ingot-withdrawal, until switch 29 is actuated to re-open the valve 25, releasing the pressure above the piston 16 and allowing the springs 18 to restore the mould. Alternatively the spring 18 is omitted and fluid supplied above and below the piston 16. In a modification, Fig. 1, the mould is reciprocated at regular intervals by securing it to a cylinder 12 containing a differential piston 16. In a further modification, the mould is reciprocated by connecting it to spring-loaded pistons similar to the pistons 16 referred to above, and alternately supplying and discharging fluid above and below the piston. Specifications 437,064 and 806,803 also are referred to.

Filed: 1923-07-30
Abstract: 201,573. Blßthy, O. T. July 29, 1922 [Convention date]. Induction motor meters.-The magnet system comprises a series core, a shunt core and a shunt portion arranged at right-angles to the bed-plate, and the pole-shoe of the shunt core is detachably 'mounted, the series core and shunt portions carrying the spindle bearings and other mechanism. In one construction, Fig. 1, an E-shaped laminated core is secured at right-angles to the bed-plate d by hammered projections x, and carries a shunt winding on the portion b and a series i on two projections of the portion a. A separate and detachable pole-shoe f is mounted on the free end of the portion b and co-operates with the shunt portion c. The pole-shoe is adjustably secured to the shunt core by a wedge k driven into a transverse slot s in the laminations. Brackets g mounted on the portions a, c carry the spindle bearings. In another construction, Fig. 3, the shunt core b and shunt c form one laminated element and the rear wall of the meter constitutes the bed-plate, and in part completes the magnetic circuit. The series core can then be constructed with less iron than the laminated shunt element, by making the part a of simple sheet metal, and it can be arranged laterally with respect thereto. In a further construction, Fig. 6, the series element a is a U-shaped metal plate and the shunt element comprises laminated iron portions c<1>, c<2> arranged symmetrically on either side of the shunt core b. In another construction, Fig. 8, .both the series element and the shunt portion c are of U-shaped plate and are connected by a piece h which may be formed integral with the U-shaped members thus producing a C-shaped structure. The torque is adjusted by a set-screw m working in an openended slot in the portion c by which the distance between the free ends of the portions b and c, and the distance of the pole-shoe from the disc are varied. The set-screw engages a tapped hole in the pole-shoe and is locked in position by a nut r. The wedge k may be driven between the poleshoe and shunt core, or between the laminations of the latter.

Title: Process for separating organic compounds
IPC: C07C7/13
Filed: 1959-06-08
Abstract: A close-boiling mixture of organic compounds containing compounds of approximately equal polarity and differing in molecular weight by at least 10 is separated by passing through a molecular sieve having the faujasite crystal structure whose pore diameter is larger than the maximum dimension of the minimum projected cross section of the compounds, and recovering an effluent containing the lower molecular weight component in increased concentration.  Separation is preferably effected in the vapour phase by injecting 1-5 parts of weight by mixture per 100 parts of adsorbent into a continuously flowing inert gas stream and collecting the various fractions. Suitable gases are helium, nitrogen, hydrogen, methane, argon, flue gas and propane. The sieve preferably has a pore size of 10-13  . The following separations are referred to cyclohexane from dimethylcyclopentanes, cycloalkanes from branched chain alkanes having one more carbon atom, e.g. cyclopentane from 2, 2-dimethylbutene (where a normal paraffin is also present this may be first removed by a 5  sieve), normal alkanes from higher molecular weight branched chain alkanes, e.g., n-heptane from 2, 2, 4-trimethylpentane (isooctane), mixtures of aromatic hydrocarbons, of olefines or of naphthenes and paraffins into fractions containing compounds having the same number of carbon atoms, e.g. a natural gasoline containing C4-C7 saturated hydrocarbons into separate C4, C5, C6 and C7 fractions.  The separation of alcohols, ketones, aldehydes and halohydrocarbons is also referred to.

Title: Improvements in or relating to roll-over toys
IPC: A63H17/00
Filed: 1939-07-05
Abstract: 533,428. Mechanical toys. MARX & CO.. Ltd., L. (Marx & Co.. Inc., L.). July 5, 1939, No. 19615. [Class 132 (iii)] A toy device comprising a body mounted on wheels with a driving motor has a reaction member operated as to cause the body to roll over by engaging the surface on which the toy runs. A spring motor 22, Fig. 2, drives the rear wheels of a toy dog, the speed being limited by a weight 42 reciprocated at high speed by an eccentric 50 rotating in a slot in arm 44. A mutilated gear 52 intermittently rotates gear 56 to which is attached the reaction member in the form of a tail 18 curved towards the front and which causes the dog to roll over sideways and upright before running forward again, the body shape causing a slight change of direction. In a toy aeroplane, Fig. 9, which turns through a right angle each time it rolls over, the mutilated gear in this case being formed from a disc 160, Fig. 6, part 158 of the periphery of which is displaced sideways, so that both parts drive a long pinion 146 and the wheels 116 continuously, while the offset part 158 drives a short pinion 154 and the reaction member 130 intermittently. To facilitate the rolling, in a modified aeroplane, an arcuately bent piece of wire joins the wing tips and the reaction member is supported ordinarily above floor level by having the mutilated part of gear not cut to full root depth. A toy cat is made to roll first to the right and then to the left as follows. Ratchet 340, Fig. 15, rotates disc 326 by engagement with spring pressed pawl 342 so that crank pin 328 reciprocates connecting rod 330 to oscillate crown gear 334 which therefore turns reaction member 314 first in one direction then in the other. The ratchet mechanism allows the reaction member to fall gravitationally towards the end of its movement in a life-like manner.

Abstract: 674,753. Public address systems; receivers. FOOT, V. A. April 27, 1950 [July 27, 1949], No. 19748/49. Class 40 (iv). [Also in Group XL (c)] In a system of sound distribution to portable receiver units individual to members of an audience, particularly for deaf-aid or simultaneous translation purposes, each receiver comprises a magnetic core member H which detects the fluctuating magnetic field produced in the building by a large coil energized from an audio frequency amplifier and causes the response of a co-operating armature G and diaphragm F. The armature may form part of the diaphragm or, as shown in Fig. 2, a separate armature is secured to the diaphragm and cooperates with a small air gap between two polepieces forming the magnetic core H. These pole-pieces are secured to a casing D and are magnetically biased by a permanent magnet, Figs. 3 and 4 (not shown), which is arranged to shunt the air gap and possesses a low incremental permeability so as to avoid by-passing the induced magnetic field. Alternatively a separate magnet may be arranged along each pole-piece. An ear-piece E which carries the diaphragm is attached to a head-band and is locked to the casing by a ring E1 so that the casing is free to rotate, the variable inclination of the magnetic pole-member providing a volume control arrangement. In an alternative construction providing a lorgnette type of receiver, Fig. 5, a further core member H, which may be an extension of one of the polepieces, is fitted in a handle M and is encircled by a coil L. The induced field in the pole-pieces is then augmented by the coil L which is connected to small coils K. According to the Specification, the large coil has its turns spaced apart in order to reduce their mutual inductance. Alternatively, the magnetic field may be produced'by a smaller coil which encircles a long magnetic core, for example steel girders or pillars in the building. Mention is made of transmitting two separate programmes simultaneously by the use of two coils arranged at right angles, programme selection being effected by varying the space position of the receiver.
