Filed: 1939-10-03
Abstract: 570,037. Explosives. JACKSON, L. MELLERSH-, (Hercules Powder Co.). Oct. 3, 1939, No. 27126. [Class 9 (ii)] Smokeless-powder grains are coated with a water-soluble deterrent substance, either in the form of an aqueous solution, or by adding the deterrent substance to wetted powder grains and mixing. When a solution is employed, it may be only sufficient to moisten the grains, or added in excess with subsequent removal of the surplus. The treated grains are finally dried to remove the moisture therefrom. In one example, two parts by weight of a 15 per cent nitroglycerine powder were wetted with 10 per cent by weight of water and 2.5 parts by weight of glycerol diacetate added. The mixture was revolved in a tumbler barrel for 15 minutes at 35‹ C., then for 15 minutes at 55‹ C., removed, and dried for 40 hours at 55‹ C. In a second example, one part by weight of a 20 per cent nitroglycerine powder was treated with 160 parts by weight of a 3.5 per cent solution of methyl cellosolve adipate, warmed slowly to 90‹ C., kept at this temperature for one hour, and dried for three days at 55‹ C.

Title: Improvements in train braking systems
IPC: B60T8/18
Filed: 1935-10-05
Abstract: 463,670. Fluid - pressure brakes. GRESHAM & CRAVEN, Ltd., and GRESHAM, J. N. Oct. 5, 1935, No. 27577. [Class 103 (i)] The braking force of a vacuum brake on a locomotive tender is regulated according to the depth of matter in the tenders by varying the degree of vacuum in the top of the brake cylinder. A pipe a is connected to the ejector or source of vacuum, a pipe b is connected to the upper chamber of the brake cylinder, a pipe c is connected to the train pipe and a pipe d to the water in the tender. The load of water exerts pressure on a diaphragm e and if the load is light when the brakes are applied, the admission of air to the train pipe and pipe c causes the diaphragm j to raise the valve carrier k<1> closing a valve m, the stem o of which opens a valve u, so that the upper cylinder chamber is cut off from the vacuum supply and connected to the reduced vacuum of the train pipe thus reducing the brake application. A spring f may be adjusted in order to regulate the valve. According to the Provisional Specification the valve may be used for a compressed air system.

Filed: 1974-06-21
Abstract: 1507675 Metal sheathed heating cables PYROTENAX OF CANADA Ltd 20 June 1975 [21 June 1974] 27623/74 Heading H5H A metal sheathed mineral insulated cable has a resistive layer 4 embedded in mineral insulation 2 and contacting elongate supply conductors throughout their lengths, the resistive layer 4 consisting predominantly of resistive material without significant admixture of insulating material. As shown the sheath forms one conductor 3 and a wire I embedded in the insulation 2 forms the other conductor. Both conductors may be embedded in the insulation 2 (Fig. 3, not shown). The sheath 3 may have an external insulating coating or may be surrounded by a further layer of mineral insulation in a further metal sheath. The resistive layer 4 may be powdered carbon. A paper tape substrate impregnated or coated with graphite may be used to form layer 4, the tape being sandwiched between semiannular blocks of MgO insulation which are crushed to form insulation 2 during the sheath reduction stage of manufacture of the cable. The paper is carbonized during the annealing stage. A textile tape substrate e.g. glass fibre, coated with resistive material may be used, the glass fibre tape fragmenting during the reduction stage. The coating may be colloidal dispersions of graphite and molybdenum disulphide. Such a dispersion may be coated on semi-annular MgO blocks which are inserted in a metal sheath to contact a central conductor. The blocks are fragmented during the sheath reduction process, but the coating forms a resistive layer engaging the sheath and the central conductor.
