Title: Improvements in or relating to the means employed for releasing the brakes of vacuumautomatic brake cylinders
IPC: B60T13/46
Filed: 1920-08-31
Abstract: 171,514. Pinder, T. Aug. 31, 1920. Fluid-pressure.-Valve apparatus for releasing automatic vacuum brakes on a detached vehicle, of the kind in which a valve is adapted to be opened to connect the upper and lower chambers of the brake cylinder comprises an additional valve which cuts off the lower chamber from the train-pipe before the two chambers are connected. The train-pipe and upper and lower brake cylinder chambers are connected respectively at 2, 4, 5. The valve 9 controlling communication. between the upper and lower chambers of the brake cylinders is adapted to be unseated by the guide members 25 of the valve 7 which controls the connection between the train-pipe and the lower chamber through the passages 3, 6. Normally the valve 7 rests as shown upon a nut 16 on a spindle 15 which is held in position by a spring 18 abutting against a lever 19, which is held by the fulcrum 20. A diaphragm 13 connected to the spindle 15 closes the valve body to the atmosphere at this part. To release the brakes, the lever is pulled to one side or the other and turning upon one or other of the fulcra 20 causes the nut 16 to force the valve 7 on to its seat to close the communication with the trainpipe and the guides 25 to lift the valve 9, thereby releasing the brakes without completely destroying the vacuum in the brake cylinder. The valve 7 is held seated when the lever 19 is released by atmospheric pressure acting on its under face, the upper face being subject to the vacuum in the cylinder. The valves 9, 7 may be respectively re-seated and unseated to re-apply the brakes, by turning the lever 23 upon one or other of the fulcra 22, thereby pulling the spindle 15 outwardly so that lugs 17 on the nut 16 engage a projection 24 on the valve 17. The valve 7 is automatically unseated by the spring 26 when the vacuum is sufficiently restored in the train-pipe after coupling up the vehicle to a train.

IPC: D01D10/04
Filed: 1923-10-09
Abstract: 209,376. Marks, E. C. R., (Bemberg Akt.-Ges., J. P.). Oct. 9, 1923. Apparatus for making filaments.- The gutter or channel b over which the artificial silk &c. thread or yarn a passes, is provided with one or more bends d, and the treating liquid supplied from a vessel n is arranged to fall directly on the bend, or on one of the bends, and in such a manner that it flows along both portions k, l of the gutter. As shown, the gutter has two portions, and it is preferred that the length of the portion k should be twice that of the portion l. From the gutter, the thread passes to a spool c, on which it is further treated with the liquid passing along the portion k of the gutter. When passing over the bend of the gutter, the filaments of the thread are opened out so as to be more freely exposed to the liquid.

Title: Process of separating 1-naphthylamine-8-sulfonic acid from its isomers
Filed: 1931-09-08
Abstract: 1-naphthylamine-8-sulphonic acid is separated from the mixture obtained by nitrating and reducing a -naphthalene-mono-sulphonic acid, by precipitating as free acid by acidifying a neutral or alkaline solution containing the ammonium, alkali metal, or alkaline earth salts of the mixed acids.  The precipitation is effected with an agent of acid character stronger than the 1 : 8 but weaker than the 1 : 5 isomers, by means of a buffer agent capable of maintaining the hydrogen ion concentration of pH = 3,7 -- 5,3 in conjunction with a stronger acid.  As buffer agents, sodium bisulphite, formate, acetate and chloracetate and acid potassium phthalate are specified. According to examples, the ammonium, alkali metal and magnesium salts of the mixed acids in solution are treated with sodium bisulphite in conjunction with hydrochloric or sulphuric acids, whereby the 1 : 8 isomer is precipitated, other acids remaining in solution.

Abstract: 1454494 Fire protection means DEFENCE SECRETARY OF STATE FOR 12 July 1973 [30 May 1972] 25236/72 Addition to 1454492 Heading A5A Fire protection means external to and contiguous with a container for flammable substances, eg surrounding an aircraft fuel tank, comprises an elastomeric bag which compresses a resilient foam pad contained therein, so that on puncture by a projectile or other object the pad expands to fill the puncture space. The volume of the compressed pad is preferably 80-95 % that of its normal uncompressed volume. The pad may be of a polyurethane ether or ester and may have a reticulated structure. The bag may contain a non-combustible gas e.g. CO 2 , N 2  or a halogenated hydrocarbon, eg bromotrifluoromethane, at a pressure up to 20 p.s.i.g., and, if so, is preferably constructed of a low-permeability material. The means may be made by wrapping the foam pad in sheets of elastomer and welding adjacent sheet edges into seams to form a bag while the pad is held under compression, or by introducing foam-forming reactants into the bag. The non-combustible gas may then be introduced.

Title: Improvements relating to the waterproofing of textile and sheet materials
Inventor: COLES ERIC HARRY
IPC: D06M13/358
Filed: 1956-08-20
Abstract: Cellulosic textile and sheet materials are rendered water-repellent by applying to them derivatives of 1:3:5 triazine having at least one -NH- alkyl substituent with more than 10 carbon atoms and at least one halogen substituent, but no substituent containing solubilizing groups, and causing reaction to take place with the material, preferably in the presence of an acid-binding agent such as alkali hydroxide, carbonate or bicarbonate.  The triazine derivative may be 2-stearylamine-4 : 6-dichloro-1.3 : 5-triazine.  The acid-binding and water-repellent agents may be applied together, or separately and may be in solution, e.g. in chloroform, or in dispersion.

Abstract: Colloidal rhenium or compounds of rhenium in colloidal form on suitable carriers, together with other metals or compounds brought in known manner in colloidal form on suitable carriers, is used as catalyst in treating carbonaceous materials at high temperature and pressure in the presence of hydrogen for effecting destructive hydrogenation, for refining or de-sulphurizing petroleum products, asphalts, &c., or for converting phenols, cresols, &c. to hydrocarbons without splitting of the molecules.  Carriers specified are oxides, carbides, silicides, carbonates, borates, sulphates, sulphides, active carbon, fine coal, silica gel, pumice.  In the example, a light motor oil is heated with hydrogen at 100 atmospheres pressure to 430 DEG  C., in the presence of a colloidal rhenium-molybdenum catalyst on active carbon.
