Title: Improvements in means for controlling the brakes of front wheels of motor vehicles
IPC: B60T11/04
Filed: 1922-08-25
Abstract: 195,567. Colla, J. Aug. 25, 1922. Brakes, arrangement and disposition of; flexible transmitters. - Steering-wheel brakes are applied by means of a cable 8 looped over a pulley 34 on an operating lever, and passina over pulleys 9. 10 mounted on a bar 11 bolted to the fixed axle 1. The bar 11 bends when tension is applied to the cable and so modifies the braking action. The cable 8 leaves the pulley 10 at a point approximately in the line of the steering pivot 2 and is adjustably connected to an arm 21 on the brake-cam shaft by an eye-bolt and nut. The brake-blocks 26 are, pivoted at 28 and are expanded by the cam 24. Releasing springs 30 are hooked to lugs on the brake-blocks. The equalizing pulley 34 is braked by a spring 35, and the cable 8 may be passed several times round this pulley.
Patent GB-465705-A (GB)
Title: Improvements in or relating to the manufacture of transparent flexible sheets
IPC: C08L89/00
Filed: 1936-08-24
Abstract: Transparent sheets impermeable to liquids and gases are obtained from solutions of gelatine containing as softening agent one or more sulphonic acids of higher aliphatic alcohols or sulphonic salts thereof.  The higher alcohols referred to are those containing at least 16 carbon atoms and up to 22 carbon atoms.  The sheets are obtained by extrusion or by casting solutions of gelatine and the softening agent.  The solidified sheets may be treated with an aqueous solution of glycerine.  They may be coated on both sides with a cellulose ester solution containing tanning agents such as formalin, chromates, tannin, quinone, or glycol.  These additions also effect a more permanent adherence between the gelatine base and the cellulose ester coatings.

Title: Improvements in or relating to apportioning valves for braking systems
Inventor: PAGE WILBUR MILLS
IPC: B60T8/18
Filed: 1968-01-29
Abstract: 1,236,791. Fluid pressure brakes. CLAYTON DEWANDRE CO. Ltd. 29 Jan., 1969 [29 Jan., 1968; 16May,1968], Nos. 4489/68 and 23374/68. Heading F2F. In an apportioning valve for use in an air pressure braking system for motor vehicles, concentric inner and outer pistons 3 and 4 are adapted to be displaceable by signal pressure supplied through conduit 9 connected to the brake control line and arranged to actuate directly valve means 13 controlling flow of air pressure to the brake actuator via port 19 and a pressure-sensitive reaction piston 24 is also responsive to the active braking pressure via passage 26 and acts in a direction at right angles to the axes of the pistons 3 and 4 to force a roller member 35 along an inclined plane 36, the angle of which is variable according to the vehicle load. Fig. 2 shows the arrangement for varying the inclined plane 36 wherein a torsion spring arm 40 is clamped at one end to the member 37. In operation, under normal running conditions, the hollow spring-loaded poppet valve 13 engages a seating 14 whilst a seating 15 is spaced from the valve so that the brake actuators are connected to exhaust through a passage 18, the bore of the valve 13 and the chamber 21. When the brakes are applied, a signal input from the brake valve is introduced through the port 9 to displace the piston assembly 3, 4 downwardly to close of the exhaust connection at valve seating 15 and then displace the poppet valve 13 from its seating 14 to connect the brake actuators with the compressed air brake supply via passage 17. The downward movement of the input piston assembly is transmitted through the interconnected piston and push rods 27, 31 to the reaction piston 24, but the pressure created in the passage 18 is also transmitted through passages 26 to the outer face of the reaction piston opposing movement thereof. The degree of reaction and thus the brake in pressure created for the given braking effort is dependent upon the inclination of the yoke member and therefore upon the vehicle load. An alternative embodiment is disclosed in Figs. 6 and 7 (not shown), wherein the apportioning valve is adapted for use in a dual-line tractor-trailing braking system and wherein a relay emergency valve unit for the trailer braking section is superimposed on the apportioning valve to provide relay and emergency actuation of the trailer brakes through the apportioning valve.

Title: Improvements in or relating to cerium sulfide semiconductor material
IPC: H01L35/16
Filed: 1962-06-18
Abstract: A semi-conductor compound of expanded crystal lattice and improved thermoelectric figure of merit, is made by forming a solid solution of a major proportion of cerium sulphide, chemically stable above 800 DEG K and preferably below 1600 DEG K, with a minor proportion of a barium compound, e.g. BaS, which goes into solution in the cerium sulphide. The cerium sulphide may be made by the reaction of CeO2+H2S+carbon and the sulphide content then adjusted by melting and boiling off the sulphur from the molten sulphide to give the desired conductivity in the semi-conductor, e.g. a composition between Ce2S3 and Ce3S4.  A cerium compound and a barium compound may be mixed and treated with a sulphur-containing compound to form an alloy of cerium sulphide and a barium compound in situ, e.g. by mixing cerium oxide and a minor proportion of barium carbonate and reacting them at a gradually increasing temperature with H2S in the presence of carbon, with elimination of carbon and oxygen, melting of the alloy and cooling to give a composition of formula Ce2BaS4.  Another method is to mix barium sulphide and cerium sulphide and heating them, e.g. by compressing the mixture in a die and sintering at 1500 DEG  C. for 1 hour, then melting the sintered mass and zone leveling The barium compound may contain 4-14 atom per cent of Ba based on cerium and the weight ratio of sulphur to total metal content may be 1.3:1 to 1.5:1. Both the modified and unmodified cerium sulphide have the thorium phosphide type crystal lattice, the lattice parameter being 8.82A and 8.6A respectively. A solid solution of Ce sulphide and CaS is also disclosed as a comparison.

[Class 2 (iii)] [Also in Group III] Vitamin-containing oils and concentrates are improved or refined by treating with a de-aerated mixture of de-colorizing carbon and a solvent. The de-aeration may be effected by stirring the carbon-solvent mixture with or without heating, the vapour of the solvent forming a layer which excludes air from the mixture. Colloidal clay may be used with the carbon. Suitable solvents are heptane, ethylene dichloride, trichlorethylene, dichlorethyl ether, chloroform, ether, acetone, isopropanol, methanol, cyclohexane, dioxane, and petroleum ether. The oil to be treated may contain a solvent (preferably the same as that used with the carbon) for instance when fish oil is extracted by a solvent, the extract may be directly treated with the de-aerated carbon-solvent mixture. Oils mentioned are various fish oils, palm oil, wheat germ oil, and oils containing carotene. Examples describe the treatment of various fish-liver oils and of the unsaponifiable fraction of a fish-liver oil.

Title: Process for the production of coloured structures of vinyl polymers
IPC: C08K5/00
Filed: 1956-08-03
Abstract: Coloured structures of vinyl polymers are produced by incorporating in the polymer before working up an azine dyestuff and then working up the polymer so coloured into a shaped article. Vinyl polymers specified are polyacrylonitrile, copolymers of acrylonitrile and mixtures of such polymers.  The azine dyestuffs are those produced by heating aminoazobenzene, a nitrobenzene or a nitrosobenzene with an arylamine or hydrochloride thereof.  In examples: (1) a dyestuff obtained by fusing together dinitrochlorobenzene, aniline and aniline hydrochloride in the presence of iron chloride is added to a dimethyl formamide solution of polyacrylonitrile from which a film is then produced; (2) polyacrylonitrile is dissolved in a dimethyl formamide solution of a dyestuff obtained by heating nitrophenol with aniline hydrochloride in the presence of iron, fibres being produced from the resulting solution.
