Title: Improvements in vehicle braking
IPC: B60T8/26
Filed: 1958-09-18
Abstract: 874,968. Hydraulic braking systems. REGIE NATIONALE DES USINES RENAULT. Sept. 18, 1958 [Sept. 19, 1957], No. 29941/58. Class 103 (1). An hydraulic braking system for a vehicle comprises a pressure source, such as master cylinder 2 controlled by a driver's brake pedal 1, first and second ducts 5 and 23 leading from the source and respectively serving for feeding pressure fluid to the front and rear brakes of the vehicle for braking purposes, a valve in one of said ducts and hydraulic means connected to vary operation of the valve in accordance with the loading of one end of the vehicle thereby to establish a variable ratio between the front braking and rear braking of the vehicle in accordance with the loading conditions of the vehicle. When, with the rear of the vehicle lightly loaded so that the thrust from spring 20 is low, the force exerted by the driver exceeds a particular value, the pressure of the liquid will be sufficient to force down valve 19, which progressively closes the duct 5. The differential piston 24/25 is displaced to the right and the initial pressure existing in cylinder portion 22<SP>1</SP> will be reduced in the cylinder portion 222 in proportion to the ratio of cross-section of the differential piston 24, 25 so that the braking action on the rear wheels will be less vigorous under small loads than under heavy loads. In accordance with the load on the rear wheels, as determined by movement of the vehicle chassis, the right-hand end of lever 10 is moved so that its other end by operation of piston slide valve 7 causes a corresponding displacement of the piston 11 which alters the compression of spring 20. As the load on the rear wheels increases, it therefore requires an increased pressure in chamber 22<SP>2</SP> to depress the valve 19 sufficiently to obstruct the conduit 5 and with high rear wheel loading the pressure in conduit 23 becomes substantially equal to that in conduit 4 leading to the front wheels.

Abstract: 505,035. Electron beam valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., BRETT, G. F., and SMITH, E. O. Nov. 3, 1937, No. 30145. [Class 39 (i)] An electron beam valve has a cathode, control and accelerating electrodes both formed as hollow cylinders with slits coextensive and aligned with the cathode, and a collecting electrode formed as a flat plate perpendicular to the plane passing through the slits and the cathode. In one form, the control electrode G, Fig. 2, and accelerating electrode A both surround the cathode C ; a flat slit suppressor electrode S is disposed between A and collector electrode P. The gun electrodes may be eccentric, with the cathode nearer the slits. This gives better cooling of the control grid, which may be still further increased by copperplating or carbonizing or by providing its ends with cooling fins of carbonized metal ; cooling holes may be provided in the back portion of the accelerating electrode. A number of sets of slits may be provided, each with a collector plate and flat suppressor electrode. In another form, the accelerator electrode A, Fig. 6, surrounds the collector P. The suppressor electrode is then a hollow slit cylinder within electrode A. In a further form, the control electrode G, Fig. 7, also surrounds the collector P, outside the accelerator anode. In this case a number of systems may surround a single cathode, as shown. The cathode may be indirectly-heated and of elliptical or rectangular shape, or directly-heated. The gun electrodes may be supported by wires, or as shown in Fig. 10, by mica washers M1, M2, M3 spaced apart by beads L on support wires W and engaging the stepped ends of the electrodes. The mica washers may be replaced by ceramic washers in direct contact or by a single ceramic disc with an aperture of diameter increasing in steps.

Title: Improvements in and relating to the production of coloured filaments, fibres, threads and the like from viscose
Inventor: ENTWISTLE DONALD
IPC: D01F2/16
Filed: 1951-12-28
Abstract: Coloured viscose rayon threads are produced by dispersing colouring matter in the presence of a dispersing agent in an aqueous stable viscous solution of a fibre-forming material compatible with viscose and preferably of substantially the same viscosity, injecting the dispersion into a stream of viscose by means of a gear-wheel pump, and extruding the viscose into a coagulating bath.  The fibre-forming material is of a type which is coagulated when extruded into the type of bath used for coagulating viscose.  The material may be casein dissolved in caustic soda solution or a sodium carboxymethyl cellulose dissolved in water or caustic soda solution.  The colouring matter used is water-insoluble and chemically resistant to caustic soda, the coagulating bath and the desulphurizing agent used for treating the threads produced.  It may consist of certain unreduced vat dyestuffs, azoic dyestuffs, carbon black or mineral pigments such as burnt chromium oxide or titanium dioxide.  The dispersing agent may be a highly sulphonated castor oil, a sulphonated mineral oil or sodium cresylate.  In an example, 64 kg. of a solution containing 10 per cent of sodium carboxymethyl cellulose, having 0.45 carboxymethyl group per anhydroglucose unit, and 4 per cent of caustic soda and having a viscosity of 60 poises at 20 DEG  C. are mixed with 35 kg. of Monolite Red 4 RHVS paste containing 1.25 per cent of solid pigment and 1.6 kg. of a highly sulphonated castor oil, and the mixture is filtered and stored under vacuum for 6 hours.  The mixture is injected into a main viscose supply line at an injection ratio of 1 : 60 parts by weight and the viscose containing the mixture is extruded into an acid coagulating bath.  The coloured dispersions may be made up in large quantities at a time and stored for considerable periods without the pigment settling out.  Specifications 290,693, [Class 2 (ii)], and 711,977 are referred to.

The acidic lipid is (a) a long-chain fatty acid, or (b) an oil-soluble salt thereof, or (c) a condensation product of a long-chain fatty acid with a polycarboxylic acid of 3 to 6 carbon atoms and 1 to 4 hydroxyl groups, or (d) a condensation product of a monoglyceride, diglyceride, mixture of diglycerides or monoester of a straight-chain diol (3 to 5 carbon atoms) of a long-chain fatty acid with a polycarboxylic acid of 3 to 6 carbon atoms and 0 to 4 hydroxyl groups, or (e) a gallate of a long-chain fatty alcohol, or (f) a condensation product of a longchain fatty alcohol with a dicarboxylic acid having no hydroxyl groups and 3 to 6 carbon atoms, or (g) a long-chain fatty acid chloride. In all cases, the long-chain fatty acid or fatty alcohol has 12 to 22 carbon atoms, and except in case (g) it is saturated or trans-unsaturated; when the acid lipid is an acid chloride, the acid radical may be saturated or cis- or transunsaturated. The protein is desaturable by heat and either soluble in water or capable of being made so by the aid of heat, chemical or enzymatic treatment without loss of denaturability. The salt is of a polyvalent metal ion, e.g. calcium, and may be derived either from the oil phase (up to 4%) or from the aqueous phase (up to 6%) or from both. When the acidic lipid is a salt, this may also supply the polyvalent metal ions, when the water used is hard, this may supply the ions, when the acidic lipid is an acid chloride, the salt may be omitted altogether. The Specification includes long lists of suitable oils, acidic lipids, proteins and salts.

Title: An improved process for after-treating cuprammonium silk spun by the stretch-spinning process
IPC: D01D10/04
Filed: 1931-11-03
Abstract: Freshly spun cuprammonium silk obtained by a stretch-spinning process is wound into hank form and after being subjected to washing and other treatment is mechanically freed from water, mechanically loosened, and dried.  A centrifuging treatment is preferably employed for removing water from the hanks, and mechanical loosening may be effected by beating, or by rewinding the damp thread.  In an example, the freshly spun filaments wound in hanks are acidified and washed by sprinkling or in a bath to remove copper and are then treated with soap.  The hanks are then centrifuged until the moisture is reduced to 245 per cent of the dry cellulose.  The hanks are beaten to loosen the yarns so that they do not stick during the drying process.  In another example the hank is centrifuged and in the still moist condition is placed on a reel and the yarn is cross-wound from this reel on to another reel under light tension.  The distance between the reels is such that a further drying takes place and the loosened yarn does not stick when dried on the second reel.
