Abstract: 678,751. Marine flares. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY, C. April 10, 1951. [April 28, 1950] No. 10477/50. Class 9 (ii). A water-borne flare is surrounded by a casing containing means for ejecting the flare, the upper part of the casing being surrounded by a buoyancy chamber, the lower part of which is easily ruptured so that on discharge of the flare the unruptured part of the chamber modifies the recoil of the casing. The flare consists of a millboard tube 1 with a pressed delay 2 in 'the base below a small charge of powder, above which charge is a flare candle with attached parachute. A felt washer 3 surrounds the delay and rests on an expelling device within the metal casing 4. The expelling device consists of a mill-board tube 5 closed at each end by book-muslin discs 6, 7 and containing an explosive charge 8. This device rests on a wooden bobbin 9 on which is wound a delay fuze 10 adapted to be ignited by a percussion igniter protected by a screw-cap 11 at the base of the casing. The top of the casing is closed by a lid 12, spacers 13 being interposed between the lid and a closure plug of the flare. The buoyancy chamber consists of two annular pieces 14, 15 of sheet iron welded to the casing 4, the space between the pieces being closed by a cylindrical sheet iron wall 16 welded in position. The lower annulus 15 is of thin sheet so that it ruptures easily during ejection of the flare, water then rushing into the chamber causes an air cushion which brakes the recoil.

Abstract: 736,501. Deep well pumps. CARRUTHERS, C. J. D. April 28, 1952, No. 10675/52. Class 69 (2). [Also in Group XXVIII] A system for pumping deep wells employs sonic or subsonic waves travelling along liquid in a pipe, having a length equal to a multiple of half a wave length, to transmit energy from an impulse generator to operate a pump motor or a foot valve and a length of pipe equal to a quarter of the wave length, or of a harmonic, is attached to the system, or a quarter of a length of the pipe of the system is made of a different cross-section to control the pressure in the system. The pump piston 15C is attached to a motor piston 19C which is loaded by springs 17C, to ensure a natural frequency equal to the wave frequency, and is subjected on its upper side to the liquid in pipe 70, which is connected to an impulse generator, and on its lower side to liquid in a completely filled balance pipe 21C have a length equal to a quarter wave length. A valve 18C in the piston 19C is actuated when the amplitude of piston 19C is not correct. A modified form is described in which a bucket pump 12B is actuated by a motor 2E having a balance pipe 9E; a lubricant supply, is provided for both pistons. To eliminate harmonics, pipes having a length of a quarter of a harmonic wave. are attached to the system at points an odd number of quarter wave lengths from the generator. A number of well strings may be operated, each connected to the system at a point an odd number of quarter wave lengths from the generator, such as at A, and any string can be rendered inoperative by closing valves 3E. The pressure at the motor may be intensified by varying the cross-section of the pipe between quarter and half wave lengths from the motor. Two forms of pressure generator are described, one with a slide valve and the other with a sleeve valve.
