摘要： 402,818. Rotary engines. DAW, A. W., and DAW, Z. W., 11, Queen Victoria Street, London. June 9, 1932, No. 16272. [Class 110 (ii).] A rotary internalcombustion or steam engine, or compressor comprises oscillating vanes 7 mounted on a shaft 9, co-operating with abutment partitions 6, 6a, to form working - chambers 24-27. The shaft 9 is connected to the main shaft 18 by cranks and connecting rods 14, 15, and a sliding crosslead 16 supported on pillars 19a. In the case of an engine two inlet and exhaust oscillating piston valves 28, 28a, each alternately connect inlets 22, 22a with passages 2a, 4a, or 3a, 5a, or similar passages, axially displaced, for exhaust are controlled by the two exhaust valves. For a combustion engine combustion chambers are placed in the casing walls in communication with the passages 2a-5a. For a compressor valve spindles 32 are connected by links and bell-cranks, Fig. 25 so that two inlet valves or two exhaust valves are moved together by cams 44 on the shaft 18. In another arrangement for an engine two push rods 34 are pivoted to rocking levers having bell-cranks controlled by cams on a separate cam-shaft, running at half the speed of the main shaft, geared to the shaft 18. Other types of valve and valveoperating mechanism may be used. For an engine the sequence of firing is 24, 27, 26, 25. The impeller vanes are cooled by water or oil under pressure entering the centre and being circulated throughout the vanes and shaft. The piston valves are also cooled through oil or water circulating around the spindle 32 and valve 56 as in Fig. 21. The engine cylinder is water or steam jacketed for internal-combustion engines, steam or air jacketed for steam engines, or water jacketed for compressors. Two engine units may be arranged side by side with the crankshaft between them. The cylinder 1 may be arranged for more working- chambers than described. In a steam engine cut-off may be arranged by stepping the cams. Lubricating passages are provided for oil under pressure to flow through the impeller vanes, hub, main cylinder and shaft. In the Provisional Specification it is stated that the piston vanes and boss of the rotor are made of cast iron, steel or a light alloy with the interior hollowed out for lightness.

摘要： 339,311. Kork-N-Seal, Ltd., (Williams, G. A.). Sept. 5, 1929. Plug stoppers, bayonet-joint. - Relates to bayonet-joint stoppers of the type in which relative rotation of the closure to the vessel gives a corresponding axial movement and in which the closure member has a central recess and packing-washer. According to the invention the vessel has an inwardly re-entrant end 3, and the closure member conforms thereto in shape, and is provided with inclined ears 8 which co-operate with lugs on the part 3 to compress a gasket 6 and close the vessel 2. Alternatively the ears 8 may co-operate with inclined lugs on the part 3, the inclination of the lugs providing the necessary axial movement of the closure.

摘要： 300,784. Daw, A. W. Nov. 10, 1927. Geared vane type.-Piston vanes which may be of triangular form are carried by abutting ends of two sleeves 3 , 4b. The outer ends of the sleeves carry discs 5, 5a provided with pawls 10 for preventing reverse motion and internal arcuate racks which 'co-operate with pawls 13 carried by discs 6, 6a fast on the shaft 7 to transmit forward movement to the shaft. The fixed arcuate racks for the pawls 10 and those carried by the discs 5, 5 are spaced so that the piston vanes act alternately as abutments. The discs 5. 5a are also furnished with two external stops 39 which engage with levers 8, 8 when the latter are suitably moved by cams 9, 9 . The portion of each piston vane which overlaps the boss of the other vane is provided with a spring-pressed packing strip 21. In a modification, the pawls carried bv the discs fast on the shaft slide axially under the control of fixed cam grooves.

摘要： 198,247. Colebrooke, A. H. S., and Williams, W.. A. July 8, 1922. Vacuum tubes. - A method of renewing the filament of a thermionic valve consists in weighting the end of the filament or a cord connected therewith, and holding the valve so that the weight may fall by gravity through a helical grid, drawing after it the filament which is then secured to leading-in wires and the surplus ends cut off. In a valve having a spherical bulb, the bulb may be opened at the pip 1 or at points opposite to the ends of the grid 7. A lead or other weight 3 on the end of a cord 4 connected with the filament 5 is inserted through the opening by means of pliers 6 and falls through the grid. The filament is secured to the hooked ends 8 of leading-in wires 9. In a valve having a tubular bulb a slightly modified method may be used and the bulb may be cut annularly so as to separate it from the neck.

摘要： 187,034. Colebrooke, A. H. S., and' Williams, W. A. July 16, 1921. Vacuum tubes; low-pressure metallic-vapour apparatus. - An electrode has an insulating sleeve arranged so that at the sides of the end of the electrode a portion is uncovered, from which the discharge takes place; or both the electrodes may be so arranged. As shown, the end of an electrode 1 projects beyond a sleeve 2, and is covered by a glass or other insulating bead 4, so as to leave a side portion 1 exposed; the sleeve 2a of the other electrode 1 has perforations 2 near the end to expose the electrode. Either of the electrodes may be used in a tube with an incandescent filament electrode, the leads of which are encased in a sleeve. The 'electrodes may be made in one or more parts, and may be enlarged at the exposed ends. The tube may be of spherical, cylindrical, or flattened shape, and may contain one or more gases such as nitrogen, hydrogen, oxygen, argon, neon or carbon dioxide, metallic vapours, such as mercury or sodium, or water vapour. Phosphorus or other de-oxidizing material may be provided in the head or elsewhere to improve the vacuum and prevent blackening. According to the Provisional Specification, an electrode may extend to the end of an unperforated sleeve.

摘要： 15,511. Daw, A. W., and Daw, Z. W. June 28. Percussive hand tools; percussive drills.- Relates to means for intermittently rotating the bit or tool in hammer rock drills, percussive hammers, &c. in which the piston reciprocates without rotation, and to dÚbris-removing means for hammer rock drills. The piston 4 is held against rotation by the engagement of its rod 18 with a guide 19, by a bar integral with the cover 5 and projecting into the piston-rod, or by suitably shaping the piston 4 and cylinder 2. In its reciprocation, a rifled part 27 of the piston rod 18 oscillates a longitudinally - held rifled sleeve 25 carrying a face-toothed sleeve 28, which is held against rotation relatively thereto, but is longitudinally movable against a spring 100. The latter oscillating sleeve 28 communicates rotary motion in one direction to a second face-toothed sleeve 31 and to the drill chuck 33 or the tool, which is held against rotary motion relative to the sleeve 31, but is longitudinally movable against a spring 40. The anvil 37 may be detachable from the chuck. For removing dÚbris, a ring 63 with inner and outer annular grooves connected by radial passages, is mounted on the chuck between packings 68, 69 which are compressed by a gland cap 71 acting through removable washers 73. Motive fluid from the cylinder may pass through the guide 19, between the sleeve 25 and the pistonrod 18, through a passage 77 in the sleeve 31 and through a passage in the cap 34 to the ring 63; or water or other fluid may be supplied through a nipple 67. From the ring 63, the fluid passes to a chamber 60 in the chuck and through the drill 54. The drill is fixed to the chuck by a taper socket 38 with a square end 39. The method of assembling the tool is described.
