Filed: 1916-06-15
Abstract: 100,694. Ruths, J. C. June 14, 1915, [Convention date]. Generating by direct contact of steam.-In power-generating systems using combustible gas, for example gas from a blast furnace a, obtainable in varying quantities, and including gasmotors having variable loads, only a part of the gases is consumed in the gas-motors c which take up the average load, another part being used to generate steam in a producer e, which steam is released from a steam-accumulator g as required by the steam turbine i or other steam consuming apparatus k, which takes up the variations of the load. The pipe f may have a branch leading directly to another steam-motor. Where another steam-engine is supplied from the boiler, a regulating-device, such as a De Laval nozzle, is inserted between the boiler and the steam-accumulator. Steam from another producer may be supplied by a pipe l to the accumulator g. The valve m may be actuated automatically by the pressure in the gas-pipe or by a device in the gas-meter, and may close automatically when the pressure in the accumulator g reaches a maximum. In a modification, Fig. 3, two turbines i<2>, i arrauged on the same or different shafts are supplied with steam in series, the accumulator g being placed between them. The connexions of the pipes f<2>, are such that steam may be taken from the turbine i<2> and supplied to the turbine i at various stages.

Abstract: 1,210,359. Two-part couplings. M.K. ELECTRIC Ltd. 29 Dec., 1967 [22 Feb., 1967], No. 8521/67. Heading H2E. An electrical socket outlet having two socket contacts has a shutter 14 which is arranged to rotate to its open position only on insertion of both pins of a co-operating plug and only when the shutter has moved a predetermined axial distance away from the front wall 12. On insertion of both pins, the shutter 14 tends to rotate owing to the sloping top surfaces of projections 15, 16 on the shutter, but is restrained by engagement of the projections 15, 16 within openings 13 and by the engagement of shoulders (25) on the shutter with side faces of abutments 23 on the rear of the front wall 12. When the projections 15, 16 clear the openings 13, the shutter rotates, the shoulders (25) moving down sloping back faces 24 of the abutments 23, so allowing entry of the plug pins into the contact cavity. When the pins are withdrawn, the spring 22 produces the reverse operation to close the shutter. If only one pin is inserted, the shutter tilts to one side, its rotation being prevented by engagement of one projection 15 or 16 in an opening 13, while inward movement of the shutter is prevented by engagement of an annular shoulder 26 with conical side wall 27 of entrance well 20. Further tilting of the shutter is also obstructed by engagement of projection 17 with the edge of recess 18.

Abstract: 347,829. Changing signs. MILNER, F. E., 304, Church Street, and COOP, W., 6, Gorse Road, both in Blackpool. March 20, 1930, No. 8884. [Class 3 (i).] In composite signs in which the display sections are on endless bands each passing round a driving roller at the rear and round a stationary front member, each band 29 with its roller 28, front member 19 and driving and control means is removably fitted as a unit between runners 3 in the sign casing 1. The side frames extending from the front 19 to form bearings 23 for the roller spindle 27 are in two parts 20, 22 adjusted relatively to one another by screw and nut 24, 25 and fixed by bolts 26. Each spindle 27 carries a loose pinion 30 and a clutch 31, the pinions being all geared together and to a driving pinion 4. The clutches 31 are all thrown simultaneously into engagement by a positive rotary cam 13 which through a pivoted lever 10 and a connecting-rod 9 rocks a shaft 7 carrying arms 18 which operate the clutch levers 32 through links 55. Mechanism is provided whereby each band effects its own stoppage in the exact display position, comprising pins 40 each extending from a display section of the band. Each lever 32 is attached to one link of a spring toggle lock 46, 50, Fig. 4, which keeps the lever 32 in clutch-engaging position even when the cam 13 has pulled back the arms 18. The link 55 is made extensible to allow this to take place, being formed of parts 54, 56 threaded into a spring 53. The toggle look 46, 50 is knocked outwardly to allow the spring 53 to retract the lever 32 and declutch the band 29 by one of the pins 40 bearing on a projection 38 on a spindle 37 carrying a finger 42, the partial rotation of the spindle 37 against a spring 44 forcing the finger 42 against the toggle links. Adjacent bands 29 move in opposite senses, and the arrangement of the stopping mechanism for'any band is modified according to the direction in which its pins 40 travel. The lever 32 is pivoted to its frame lug 34 in a floating bearing 57, 58 under control of a spring 59 to allow for the possibility of the clutch teeth peaks abutting when first engaged. The cam 13 and shaft 7 may be replaced by Bowden wire mechanism. The members 19 may have rollers or rods at their edges to reduce band friction, and the bands may be perforated at their edges to engage teeth on the rollers 28. The apparatus, or two thereof arranged back to back, may be mounted on a vehicle.
