Title: Improvements in Valve Gear for Steam and similar Power Engines.
Inventor: VORRABER JOSEF
Filed: 1901-11-25
Granted: 1902-03-06
Abstract: 23,938. Vorraber, J. Nov. 25. Valve gear.-Relates to trip or releasing gear in which a lay shaft coupled to the main shaft and rotating at the same speed carries eccentrics by which the valves are opened by a lever furnished with a tripping-device, on the release of which the valve is closed by a spring. The objects of the present invention are to prevent the valve from passing beyond its middle position when released, and to improve the distribution by modifying the action of the valve during the exhaust stroke. Fig. 1 shows one form of the invention. The valve spindle o is raised to admit steam to the cylinder by the lever l carrying a tappet s<1>, which through the tail t meeting a stop b can be released so as to allow the valve to be closed by the outer spring m, the moment of closure being determined by the adjustment of the stop b effected by the engine governor acting on the shaft u. The valve is prevented from falling below its middle position by being connected to the piston q, not directly, but indirectly through the medium of an inner spring c. The distribution is improved by providing two suitably-shaped cams side by side on the shaft e in place of an eccentric, one cam x for controlling the admission and the other y controlling the exhaust and compression.

Granted: 1902-12-04
Abstract: 58. Ransford, R. B., [Cassella & Co., L.]. Jan. 1. p-Amidotolyl-p-oxyphenylamine is produced by oxidizing a mixture of p-amidophenol and o-toluidine with sulphuric acid and sodium bichromate at a low temperature, and then reducing the oxidation product by means of sodium sulphide at 85‹-90‹ C. The hot solution is filtered, and the new product is precipitated by addition of sodium bicarbonate and common salt. After purification and recrystallization from benzene, it is obtained as greyish-white needles melting at 160‹ C. Dyes, artificial.-Dyes, which have an excellent affinity for the fibre and dye indigo-blue shades on unmordanted cotton, are produced by heating the foregoing p-amidotolyl-p-oxyphenylamine with a polysulphide, such as sodium polysulphide, at 120‹ C. for about 20 hours, then dissolving the melt in water, and precipitating the dye by a current of air. If a higher temperature is employed, the dye produced yields more greenish and duller shades, while that produced at a lower temperature, or in alcoholic solution, yields more reddish and brighter shades.
