Abstract: 545,190. Enamels and glazes; glass manufacture. EVERY, C. E. (Titanium Alloy Manufacturing Co.). Aug. 13, 1940, No. 12962. [Class 56] A composition which on smelting forms a relatively translucent frit from which a highly opaque enamel can be produced comprises a zirconium compound, a fluorine compound, and at least five per cent. of aluminium, Similar compositions may be used for producing glasses of various degrees of opacity. The content of zirconium should be 1-9 per cent. preferably the amount of aluminium should lie between 6- and 10-per cent., and of fluorine 3.5-15 per cent. The frits produced by smelting are translucent but the addition of a small amount of a zirconium compound in the mill cause the production of a dense opaque enamel on the ware. The zirconium compound used is preferably zircon. Aluminium hydrate may be used to supply the aluminium, but pyrophillite is preferred although sillimanite, andalusite, bauxite, kyanite, or china clay may be used. Cryolite, fluorspar, or sodium fluosilicate may be used to supply fluorine. The materials must be free from all but the smallest traces of iron, chromium, manganese, vanadium, nickel, and titanium when producing white enamels, but their presence may be permitted when producing coloured enamels. Other compounds, such as those of boron, silicon, calcium, sodium, &c., are included as usual in compounding the enamel. Compositions of a number of suitable batches are given in the Specification.

Filed: 1929-04-29
Abstract: 335,590. Kasantzeff, F. April 29, 1929 Fluid-pressure.-A triple valve B for compressed air brakes comprises a freely movable piston one side of which is directly connected to the train pipe and the other side to a chamber 14 which during brake application remains closed and filled with a constant pressure and during brake, release this pressure is reduced to an extent corresrponding to increase of train pipe pressure. A secondary reservoir 19 connected to the chamber 14 supplies the auxiliary reservoir 20 during brake release. The pressure in the brake cylinder 21 is controlled by the valve B comprising a double valve 5 controlled by a double piston 1, 3 influenced by the pressure in the chamber 14, in the train pipe 17, the brake cylinder and a spring 4. On charging, train pipe pressure moves a piston 7 to the right opening a valve 8 and air is supplied by a passage 18 and the valve 8 to the chamber 14 and the reservoir 19 also to the reservoir 20. Both reservoirs are also supplied through an accelerating-chamber 11. On brake application, the brake cylinder is charged from both the train pipe and the auxiliary reservoir to any desired pressure by the valve B and the piston 7 moves to the left, owing to the fall in train pipe pressure, to close the valve 8 and the passage 18. On brake release the brake is released to any desired extent by the valve B and the piston 7 is moved to the right by increased train pipe pressure and opens the valve 8, so that air passes from the chambers 14, 19 to the auxiliary reservoir 20. Valves 5, 8 are reclosed at each stage of the release when the auxiliary reservoir and brake cylinder pressures balance train pipe pressure.
