IPC: A62C5/00
Filed: 1961-08-01
Abstract: 950,879. Fire extinguishing. H. ALERS HANKEY Ltd. Aug. 1, 1961 [Aug. 15, 1960], No. 27959/61. Heading A5A. [Also in Division B1] A method of fighting fires in sloping mine tunnels includes locating an open vessel containing foam-forming liquid in the tunnel at a level lighter than the fire, agitating the liquid by gas jets and allowing the foam to exude from the vessel and gravitate on to the fire. An apparatus comprises a rectangular casing 2 having a side opening 5 and supplied with foam forcing liquid 18 through a pipe 7 and nozzles 10. Compressed air is forced into the liquid through parallel pipes 13, each having a row of submerged orifices 16 directed so that the air jets impinge on each other in a corner 17 of the casing. The resulting agitation forms foam 19 which exudes through the opening 5. The casings may be divided into compartments by transverse partitions 6 to prevent the pipes 13 becoming uncovered on uneven floors, the tops and bottoms of the casings are flat to permit stacking in use. The amount and proportion of foam-forming compound supplied to the apparatus may be regulated, see Fig. 4, (not shown), and Division B1.

Title: Presses
Inventor: WALKER JOHN GORDON
IPC: B30B15/16
Filed: 1967-06-19
Abstract: 1,221,656. Hydraulic presses. FORSYTH PRESSES Ltd. 8 April, 1968 [19 June, 1967], No. 28134/67. Heading B5F. In an hydraulic press including a doubleacting piston, one side of the piston is connected to the other via a one-way valve so that fluid displaced from said one side is returned through the valve to said other side thereby supplementing the fluid fed to said other side and increasing the speed of the piston. In the embodiment shown in the figure, the doubleacting piston 3 is controlled by a valve box 2 itself controlled by a manual linkage. The outlet of the right hand valve 8 of the valve box is connected via a first spring biased one-way valve 4, to the space above the piston or via a second similarly biased valve 9 to reservoir. In operation, appropriate movement of the linkage causes fluid to pass through valve 7 to the upper side of the piston, the fluid displaced from below the piston being displaced through valve 8, and preferentially through valve 6 back to the space above the piston, thereby increasing its speed. At the end of the working stroke, when the workpiece is encountered, the pressure above the piston is increased to a pressure at which the valve 4 is closed and the liquid displaced from below the piston opens valve 9 and flows to reservoir and the speed of advance is slowed down. During the retraction stroke, for which the valve 2 has been appropriately adjusted by the linkage, reverse flow through valves 6 and 9 is not possible, and the fluid displaced from above the piston flows through valve 7 straight back to supply.

Abstract: 681,609. Washing gases. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 26,1950 [Nov. 3, 1949], No. 28172/49. Class 55 (ii) In the removal of dust particles from a stream of gas, a liquid spray is projected across the gas stream, the spray being composed of drops of the same order of size as the particles to be removed and having a velocity which is high relatively to the velocity of the gas stream. As shown, the spray is produced by revolving discs 11 mounted on a shaft 12 driven by a steam impulse turbine 14, a governor 15 for the turbine being mounted on the other end of the shaft. The turbine and governor are supported from the casing 10 by radial tubular struts 16 which are used also for the supply and exhaust of steam and for the supply of water and lubricant. The turbine and governor are covered by fairings 9 to avoid turbulence in the gas stream. A plate 18 gives access, to the spray producer when required. Water from one of the struts 16 is fed through a distributer 19 to the discs 11, the water being led through holes in the spacing collars to emerge on the surfaces of the discs. The discs are rotated at sufficient speed, e.g. 5,000 r.p.m., to ensure that with, say, a 6 inch wide passage between the edges of the discs and a 28 inch diameter casing, the drops hit the casing at about one-fifth of their initial velocity. The water, with collected dust is removed through a drain hole 20, but some of the dust-water particles are entrained in the gas and are removed in a separator consisting of spaced parallel sharply corrugated sheets, the gas flowing transversely to the corrugations. Specifications 22282/02, [Class 55], 17696/10, 23864/11, [both in Class 55 (ii)], and 583,196 are referred to.

IPC: H01H71/68
Filed: 1922-10-20
Abstract: 214,667. Whipp, F., and Whipp & Bourne, Ltd. Oct. 20, 1922. Electromagnetic switches, or other electromagnetically-operated mechanisms controlled from a distance by a three-position handoperated control switch g, as described in Specification 22646/12, are provided with an economy resistance for the maintaining circuit, in two parts, one of the parts being introduced into the operating circuit by the removal of a short-circuit therefrom before the operation is complete and, consequently, before the overload trip mechanism can come into operation. The arrangement avoids damage to the contacts of the overload trip switches in the event of faulty conditions arising while the control switch is held in the circuit closing position. As shown in the. Figure, applied to the control of a contactor, the resistance section d<1> is normally short-circuited by the auxiliary two-position switch e on the contactor. Consequently, for initial operation full voltage is put upon the operative winding a, but at the commencement of the movement, or at some short time after as determined by time-lag devices to prevent hunting the short-circuit is removed. The overload trip contacts c operated by the overload coils b cannot effectively close a short-circuit on the operating winding until the switch e closes its upper contacts thereby ensuring that the resistance section d' is in series with the winding a before the short circuit thereon for automatic release is introduced. Both sections d<1>, d<2> are inserted in the maintaining circuit when the auxiliary contacts f of the contactor close.
