Title: Improvements in Automatic Fire Extinguishing Sprinklers.
IPC: A62C37/14
Filed: 1919-03-17
Abstract: 125,058. General Fire Extinguisher Co., (Assignees of Loepsinger, A. J.). March 30, 1918, [Convention date]. Drawings to Specification. Sprinklers, automatic, of the type in which the valve is normally held on its seat by a frangible vessel nearly filled with a liquid, the expansion of which is adapted to fracture the vessel and release the valve. The liquid is free from gas, and the expansion space is filled with a gas sparingly soluble in the liquid at atmospheric pressure, so that the gas is forced into solution by the increase of pressure on expansion of the liquid, and is released with explosive force on fracture of the vessel, thus shattering the vessel and ensuring unseating of the valve. The liquid is preferably one, such as carbon tetrachloride, which has a boiling-point higher than the usual fracturing- temperature and a high co-efficient of expansion. The gas is preferably air.

The anode 16 is rounded at one end 18 and supported by a polygonal mica disc 17, and at the other end fits into the end of an exhaust tubulation 19 made of an alloy having substantially the same coefficient of expansion as the glass of the header dome 12 through which it is sealed. The dome, 12 exhaust tubulation 19 and anode 16 can thus be assembled as a unit prior to fusing the dome 12 to the envelope 10. The internal diameter of the tubulation 19 is larger than the external diameter of the anode rod 16 and the tubulation is pressed inwardly at opposite sides near its end to contact the rod at a number of points at which welding is effected, leaving a plurality of ports for evacuation of the device and the introduction of a filling such as hydrogen at a pressure of 40 1b. square inch. The tubulation 19 is sealed by means of a glass pellet 22 which is melted by h.f. induced heating and runs into a constructed portion 20 of the tubulation which is provided with a metal heat concentrator 24. The external portion of the tubulation 19 then serves as the anode lead-in. In a modification the anode may be a stainless steel tube, both ends of which are open to facilitate evacuation of the device. The anode 16 may then be a tight fit in the tubulation 19. Alternatively the anode may be an integral continuation of the exhaust tubulation.

Title: Hydraulic piston drive for actuating reciprocating slides in machine tools and similar machines
IPC: B24B47/06
Filed: 1934-03-07
Abstract: 416,899. Actuating machine-tool slides. FORTUNA - WERKE SPEZIAL - MASCHINENFABRIK AKT.-GES., Cannstatt, Stuttgart, Germany. March 7, 1934, No. 7243. Convention date, Jan. 10. [Class 83 (iii).] In hydraulic means for operating a machine tool or like slide, the whole surface of a piston is operative for moving the slide up to working position, and a portion only of the surface is then operative for effecting or controlling the feed movement of the slide. The figure shows an internalgrinding machine, the grinding wheel spindle 4 being carried on the upper of two transverse slides 5, 6, the upper slide 5 being adjustable by a hand-wheel 7 on the lower slide 6, and the latter being connected to the piston rod 8 of an hydraulic cylinder. The piston 9 is slidably mounted on the rod 8 to move between stops 19, 20, and during movement of the slide to and from operative position it bears on one or other of the stops 19, 20. When the operative position is reached, the piston 9 is arrested by a shoulder formed by a front part of the cylinder of reduced diameter, so that the piston rod 8 moves through the piston during the working portion of the stroke, which therefore takes place under reduced load. In the form shown, the piston is held in contact with the end of a screw 16, which is rotated by a hand-wheel to force the piston back to make the working stroke. Alternatively, the movement may be effected by the forces produced by the piston, and be controlled by the screw 16.

Abstract: 290,594. Schneider et Cie. May 16, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts] Selective distant control systems; order apparatus.-Angular movements are repeated at one or more distant stations by wireless, and utilized to operate an indicator or effect gun control. Selection is determined by the modulation frequency. Fig. 1 shows a tuned circuit comprising the inductance 1 and the condenser 2, 3, 3<1>, of which the plates 3, 3<1> are continuously rotated so that the frequency varies between the limits of the modulating frequencies used. The received signals are applied to an amplifier and detector 17, the output from which is applied through transformer 19 to the electrodes 15, 16 of a neon tube 14. A disc 12, driven from the shaft 5 carrying the plates 3, 3<1>, is provided with an aperture 13, the position of which at the flash indicates frequency and so the transmitted signal. The disc 12 preferably turns at sufficient speed so that the flash appears continuous owing to the persistence, of vision. Instead of the capacity, the inductance of the tuned circuit may be varied. At the control station the inductance or capacity in a tuned circuit associated with the modulating valve is varied in a continuous manner in dependance on the control handle. Fig. 2 shows the application to a control system in which the secondary coil 21 of the transformer 19, Fig. 1, is connected to a brush 22 and to one side of relay windings 33, 34. The slip ring 23 and brush 24 are driven from the same shaft as the condenser plates 3, 3<1>, Fig. 1, while sectors 25, 26 are driven from the motor effecting the control which is controlled by the relays 33, 34, so that at the time when the signal is received the brush 24 bears on the insulation between the sectors 25, 26.

Title: Improvements in or relating to vacuum brake apparatus for railway trains
IPC: B60T13/46
Filed: 1924-03-24
Abstract: 234,228. McDermid, W. F. March 24, 1924. Fluid-pressure. - In vacuumbrake apparatus in which an auxiliary reservoir is provided to accelerate the release of ,the brakes, two automatic valves are arranged in connection with the reservoir and the train-pipe so that (1) the acceleration of the release of the brakes is effected during the last stages of the releasing operation, and (2) during the application of the brakes the auxiliary reservoir is connected to the upper side of the brake cylinder in order to minimize the reduction of effective vacuum above the piston as it rises in the cylinder. The. two valves are shown housed in a common casing 7 having a spigot 27 connected to the train-pipe, a spigot 28 connected to the under side of the brake piston and the usual non-return ball-valve and a spigot 14 connected to the main vacuum reservoir at the upper side of the piston. A passage 12 of the casing is connected to the auxiliary reservoir. The release accelerating valve comprises a solid piston 18 slidable in a ported liner 33, and having at one end a port 40 adapted to close a valve opening 23 leading to the auxiliary reservoir, and at the other end a light valve 24 mounted to slide on the centre rod 42 and adapted to close the ports in the base of the piston 18. Connecting passages are arranged in the wall of the casing. When the brakes are applied, the air admitted from the train-pipe through the spigot 27 raises the valve 24 and the piston 18 and so closes at 23 the connection between the train-pipe and the auxiliary reservoir. The air passed to the brake cylinder through ports 26 and the spigot 28. An ejector 29 is arranged in its path to reduce the pressure in the passages leading to the auxiliary reservoir. When evacuation of the train-pipe is commenced in order to release the brakes, the valve 18 will remain seated until the pressure below it is insufficient to support its weight, whereupon it will drop and will open connection between the auxiliary reservoir and the brake cylinder and so accelerate the release of the brakes. The valve which is arranged to connect the upper part of the brake cylinder with the auxiliary reservoir during an application of the brakes consists of a tubular member 17 housed ir a chamber 10, and seating on a valve seat 19. The valve is weighted by a suitable number of rings 21 so that it will lift to make the connection when a predetermined pressure difference exists on its two sides. When the vacuum-brake apparatus is adapted for working at times as a compressed air brake, a valve such as that described in Specification 208,221 may be fitted in an extension 48.
