Title: Improvements in and relating to the production of artificial filaments, yarns, threads, and the like from viscose
Inventor: TYLER DAVID NICHOLSON
IPC: D01F2/10
Filed: 1955-05-09
Abstract: In the production of regenerated cellulose filaments and like products from viscose, there is added to the viscose 0.5-10 per cent by weight, based on the weight of the cellulose in the viscose, of a water-soluble compound of average molecular weight 600-10,000, preferably 1000-3000, obtainable by the action of at least 7 mols. of ethylene oxide on one mol. of an aliphatic acid, amide, alcohol or aldehyde, and the viscose is extruded at a salt point of 5-18 into an aqueous coagulating bath containing sulphuric acid in a percentage equal to 0.8-1.5 times the percentage of caustic soda in the viscose and 3-20 per cent of zinc sulphate.  The polyethylene oxide condensation product preferably contains 24-72 ethylene oxide mols. and the acid, amide, alcohol or aldehyde used as a starting material may have a carbon chain of any desired length, subject to the prescribed limitation regarding the molecular weight of the condensation product.  The viscose may be spun in an unripened condition.  The freshly spun filaments are preferably stretched while they are passing through an aqueous bath of a hot dilute acid, as described in Specification 467,500, [Group IV].  The percentage of caustic soda in the viscose is preferably 6-8 and the preferred total sulphate concentration in the coagulating bath is 18-26 per cent. In an example, viscose containing 7 per cent of caustic soda, 7.5 of cellulose, 41 of carbon disulphide (based on the weight of alpha-cellulose) and 1.0 (based on the weight of cellulose) of the condensation product of 27 mols. of ethylene oxide with 1 mol. of ricinoleic acid is spun at a salt point of 11.9 into an aqueous coagulating bath containing 7.7 per cent of sulphuric acid, 14 of sodium sulphate and 9.4 of zinc sulphate and having a temperature of 55 DEG  C.  The filaments are withdrawn from the coagulating bath and stretched 87 per cent in a hot aqueous bath containing 3.0 per cent of sulphuric acid, 0.8 of sodium sulphate and 0.4 of zinc sulphate. The filaments produced have a thick skin, a non-crenulated surface and a high wet tenacity.  Specifications 541,099, [Group IV], 785,616, 792,548, and U.S.A. Specification 2,359,750 also are referred to.

Patent GB-135541-A (GB)
IPC: B61G3/02
Abstract: 135,541. Atkinson, F. W., and Firth, H. de G. March 14, 1919. Couplings, automatic.-Relates to automatic couplings for railway &c. vehicles of the type comprising interengaging draw-hooks B on each vehicle pivoted at D to the draw-bars so as to swing in a horizontal plane and working in horizontal slots G in the ends of the vehicle under the influence of springs H. According to the invention, the points C of the hooks are provided with pairs of upstanding lugs J adapted, for uncoupling purposes, to be engaged by pairs of cam fingers I pivoted on the hooks and operated from the side of the vehicle through the medium of a lever O, a worm segment wheel N, and a worm M mounted on a rotary shaft L. When the shaft L is rotated, the hooks being in the coupled position as shown, the cam fingers I are rotated so as to engage the lugs J and force the hooks apart and at the same time bridge the recess E behind the point C of the hook to prevent re-engagement of the hooks. Continued rotation of the shaft L causes the hook B to be drawn aside laterally out of the path of the complementary hook, thus locking the coupling in its inoperative position, for example, for shunting purposes.

Patent GB-136559-A (GB)
IPC: H02K7/20
Abstract: 136,559. Paratore, G. Dec. 11, 1918, [Convention date]. Systems for alternating-current motors only.- A working motor m is supplied from an asynchronous generator a which has a slip ring rotor driven at a constant speed and energized with alternating current from a synchronous generator b. When the speed of the rotary field relatively to the rotor conductors is equal and opposite to the speed of the rotor conductors, no current will be generated by the machine a and the motor m will not rotate. If the speed of the generator b is now increased or diminished, the motor m will rotate in one direction or the other at a speed depending on the frequency supplied. In a modification designed for ship propulsion, a rotary converter is mounted on the shaft of the generator a. During the period of manoeuvre, the converter supplies direct current to the motor driving the exciter b, but at the normal speed, the converter supplies the alternating current for the excitation of the generator a. In another modification, for rolling-mills, hoists, and the like, the generator a is driven by a motor n, Fig. 3, and its shaft carries a fly-wheel g. An auxiliary generator e supplies the motor d of the exciter b. Slowing down during maximum load is effected by means of a main current transformer feeding a converter which influences a field winding on the dynamo e or the motor d.

Abstract: 397,261. Lenses. KAPELLA, Ltd., 104, Stoughton Street, Leicester.-- Warmisham, A. ; 1625, Hinman Avenue, Evanston, Illinois, U.S.A.) May 14, 1932, No. 13941. [Class 97 (i).] In order to provide a photographic lens having greater depth of focus behind the plane of the principal object focused than in front of this plane, the lens is spherically over-corrected in its central zones and is under-corrected in its marginal zones by making one or more of its surfaces aspherical. Preferably the lens is first made with spherical surfaces so as to be spherically over-corrected in all zones, and then the correction in the marginal zones is inverted by removing from the marginal zones of one or more surfaces material increasing in amount regularly from zero towards the edge of the lens. In the lens shown, for which constructional data are given, the surfaces R5, R6 are deformed as above described, commencing at a zone corresponding to an aperture of about F/3-5, the amount of material removed from the edges being about 400 wave-lengths of sodium light.

A device for calculating quantities of ingredients in the mixing of ice-cream, or other comestible, comprises a holder H accommodating a plurality of slides S1, S2, &c. in juxtaposition; each slide represents an ingredient (e.g. milk-powder, cream or sugar), is divided into sections 1, and the sections bear markings 2 of quantities by weight or volume of the respective ingredients and markings 3 of the percentages or proportions of the constituents (e.g. moisture, fat and sugar) conferred on the mix by each marked quantity. As shown, the markings 3 are staggered across the slide sections so that the markings on the several slides corresponding to each constituent can be aligned vertically at the holder H and totalled. In use, the slides are adjusted until these totals correspond to the constituent percentages of the recipe under preparation, and the markings 2 on the slide sections in register with the holder will then give the quantities of the several ingredients required. Modifications are described: (1) in which the slides are in the form of a series of discs of decreasing diameter and rotatable about a common pivot in a sectorshaped hollow, and (2) in which the slides are replaced by a set of coaxial drums rotatable about a spindle between the arms of a U-shaped holder.
