IPC: B24B27/00
Filed: 1919-03-24
Abstract: 130,927. Lumsden, T. March 24, 1919. Disk apparatus.-A machine for grinding gauges and form-tools comprises a bed a in which are mounted three bars b, c, d, the bar b carrying a swinging arm j, on which is mounted the grinding-disk k<1>, and being movable longitudinally by means of a hand-wheel f and rack-andpinion gear, and the bar c having pivotally mounted thereon a work-table u. The swinging arm is located between collars b<1>, b<2> secured to the bar b, and carries a pointer l mounted in a holder l<1>, which is adjustable vertically and angularly; the arm and the grinding-wheel are normally drawn back from the work by a spring n<3>. The work-table u, which carries the work and also a pattern, may be clamped in any angular position by means of a slot v and a nut x, screwing on the bar d, and may be adjusted laterally by means of a micrometer-wheel 2 acting through worm-gearing d<1>, y<1>. In operation, the grinding- disk is held up to the work-blank, against the resistance of the spring n<3>, by means of a lever m and is traversed by the hand-wheel f, the pointer at the same time engaging the pattern. When grinding snap-gauges, the final cut is made by clamping the bar b by means of the clamp-lever b<5> and moving the work by means of the micrometer-wheel. In order to grind the converse of the pattern, a pointer having a bent-back end is employed.

Abstract: 235,325. Donald, W. March 24, 1924. Small chambers; trucks, moving; special pressures, drying at.-Apparatus for drying peat &c. by first subjecting it to radiant heat in a boiler until the vapour pressure exceeds that of the atmosphere, then reducing the pressure while continuing to apply heat, and finally reducing the pressure to that of the atmosphere comprises a boiler a, Figs. 1 and 2, having steam-tight doors a<1>, a<2>, a pressure gauge b<1>, and an outlet valve b<2>. The boiler is heated by furnaces or gas burners e in a casing c which communicates with a flue g. The peat is supported in the boiler upon wheeled trucks. In a modification in which several boilers are employed, the boilers are arranged in parallel and with pipe connections by which steam may be passed from one boiler into another in which the pressure is lower. Figs. 10 and 11 show another arrangement comprising central dehydrating- boilers a and end boilers e<6>, the central boilers being provided with burners and flues. The boilers are separated by slide valves which may be opened to facilitate the passage of the trucks. Steam may be passed from the central to the end boilers through pipes s<1>, s<3> and to either of the central boilers through pipes s<2>. Further, steam may be passed from exterior sources into the dehydrating-boilers so as to accelerate the drying. The vapour escaping from the dehydrating-boilers is used for preheating wet materials either by radiated heat or conduction.

Filed: 1963-02-26
Abstract: 980,896. Valves. ZYROTRON INDUSTRIES Inc. Feb. 26, 1963, No. 7720/63. Heading F2V. The actuating mechanism 23 of a valve is isolated from the controlled fluid by a diaphragm 21 formed integrally with the valve member 19 which is of resilient material such as rubber, neoprene &c. and coacts with a seat 25 so formed that when the valve is partially open an annular Venturi passage is provided to cause the fluid passing from the inlet 12 to the outlet 13 to assist the opening movement. Opening is also assisted by the provision of an annular bead (not shown) on the lower surface of the diaphragm which is stated to give the diaphragm a non- linear force/displacement characteristic. When the valve is closed the inlet pressure acting on the difference between the area of the diaphragm and that of the valve member provides a small net opening force to be overcome by the actuator which may be a solenoid, float, bellows or bimetal element.

Filed: 1922-03-22
Abstract: 177,530. Massolle, J., Engl, J., and Vogt, H. March 24, 1921, [Convention date]. Vacuum tubes. - Variations in the intensity of the cathode glow are used for photographically recording electric oscillations. For this purpose the intrinsic brilliance of the cathode surface is increased by covering the cathode k, except for a small area, with an insulator m, for instance of magnesia, the glow remaining permanently on the small cathode surface, which may be from 5 to 10 square millimeters in extent. The cathode mav be of iron or tungsten, of circular section, and may be mounted on a rod of good heat-conducting material such as copper. In order to prevent creeping of the glow due to disintegration, the upper part of the cathode is reduced slightly as shown. The cathode and insulator are sealed into a glassholder g. The intrinsic brilliance may be increased by forming a conical recess on the surface of the cathode. The discharge tube is preferably filled with gases of great actinic activity, such as nitrogen or argon.
