Title: Coated fabrics suitable for use as a diaphragm for a fuel pump
IPC: F04B43/00
Filed: 1948-02-24
Abstract: 684,598. Coated fabrics; coating webs. CARTER CARBURETTOR CORPORATION. Feb. 24, 1948. [Dec. 9, 1946] No. 5515/48 Class 140. A coated fabric suitable for use as a diaphragm for a fuel pump is made by applying synthetic rubber in uncured, plastic, viscous condition to the surface of a sheet of woven fabric, rolling it in the direction of one set of threads into the interstices of the fabric, and applying curing pressure to the coated fabric normal to its surface for stretching the threads of the fabric in the direction of the other set of threads to compensate for the stretching of said one set of threads incident to rolling. A tough, closely woven fabric of cotton, rayon, or nylon, which may have greater crimp in the warp than in the weft, may be used. The fabric 17, Fig. 9, optionally provided with a thin, preliminary, knife-spread coat of synthetic rubber composition, is passed between rolls 20, 21 which apply to the fabric a coating of viscous synthetic rubber composition from a mass 22 which is continuously maintained by supplying strips 23 and 24 of the composition. The pressure and spacing of the rollers is controlled by an adjustable spring device 27. The coated fabric, which has been stretched longitudinally by the calendering operation, is cut longitudinally into strips 30, Fig. 12, which are placed between metal strips 34 and hot-pressed and cured between the heated platens 35 of a press. The movement of the press-platens is slowed down towards the end of the stroke. Pump diaphragm discs are stamped from the cured strips. The synthetic rubber may be a butadiene-acrylonitrile copolymer and the priming coat may consist of a solution of the copolymer in methyl ethyl ketone. Specification 684,661 is referred to.

Title: Improvements in or relating to a diffusion apparatus for dissolving the sugar content from cossettes
IPC: C13B10/10
Filed: 1949-03-02
Abstract: 670,273. Extracting sugar. MORTON, W. V. March 2, 1949, No. 5694/49. Class 127. A diffusion apparatus for extracting sugar from cossettes comprises a number of cells through which the cossettes and solvent are advanced, means for separating the cossettes and solvent at the end of each cell and directing them in opposite directions, and means, if desired, for recirculating a portion of the solvent from the last cell through which it passes through a part of the apparatus. The cossettes are fed into the first of a series of cells 1, each of which has a semicylindrical bottom and contains a screw conveyer 4 driven from a common shaft 6, adjacent conveyers being of opposite pitch. The conveyer, at the exit end of each cell carries a number of sets of tangentiallyarranged arms 11 arranged to pass between a set of fixed arms 14, the arrangement being such that the arms 11 lift the cossettes up on to the arms 14 and push them through a delivery aperture into the next cell, or to a discharge 28. Beyond the arms 11 in each cell is mounted a screen 16 which permits the passage of diffusion liquid but prevents that of the cossettes, the last set of arms 14 acting as a scraper to keep the screen clean. The diffusion liquid is introduced through a pipe 31 into the last cell where it is fed with the nearly-exhausted cossettes, and at the end of this cell, it passes through the screen 16 and through an opening 19 into the next preceding cell. After passing through all the cells, the liquid is discharged through a pipe 24. A part of this solution can be withdrawn by a pump 26, passed to a heater 27 and then fed into a preliminary extraction unit 21, where it encounters the fresh cossettes and acts to heat them prior to their being fed into the first cell 1.

Title: Improvements in and relating to automatic control of free-piston gas-generators
IPC: F02B71/00
Filed: 1958-02-28
Abstract: 874,009. Free piston gas generators. SOC. D'ETUDES ET DE PARTICIPATIONS EAU, GAZ, ELECTRICITE, ENERGIE S.A. Feb. 28, 1958 [March 11, 1957], No. 6598/58. Class 7(1). In a free-piston gas generator the cushion pressure is controlled by a stabilizer which is operated in dependence upon the operating pressure in a reservoir from which power gas is obtained, or in the scavenge air receiver and upon a sampled cushion pressure namely a pressure taken from the cushion when the piston assembly is at a predetermined point in its stroke, in such a manner that the ratio between the maximum compression pressure in the engine part of the gas generator and the inlet pressure to the compressor part of the gas generator increases when the operating pressure increases and vice versa. As shown the stabilizer comprises a slide valve 25 controlled by a piston 33. The surface S 2  of the piston is acted on by the pressure in the engine case and the surface S is acted on by the pressure in the cushion b at a predetermined point in the stroke of the piston assembly. Thus the pipe 36 connected to the cushion b is opened when the passage 39 registers with the lower part of this pipe. The lower part of the cylinder 34 or the pipe 36 downstream of its control member 38, 39 is formed with a bleed-off connection which opens before the free piston reaches its maximum outer dead point preferably at the instant when the piston is near its minimum outer dead point and which remains open for as long as the piston is beyond the position at which the bleedoff connection is opened. The sampled pressure derived from the cushion when the piston assembly is in a predetermined position is used to control not only the stabilizer but also the timing of the fuel injection and/or the device which determines the lower and/or upper limits of the zone in whch the regulator of the receiving machine (turbine) can move the regulating member of the injection pump of the gas generator. The regulator may act on the member 19 through a linkage or through a hydraulic or electrical means. All or some of the compressed air supplied by the compressor is used to supply and scavenge the engine. The gas generator will generally comprise two piston assemblies which move in opposite directions in a single engine cylinder. The compression pressure may be increased at starting by operation of the hand wheel 45.

Inventor: ALLEN ALBERT
IPC: B21D7/06
Filed: 1967-02-11
Abstract: 1,163,407. Angular bending. C. & J. HAMPTON Ltd. 1 Jan., 1968 [11 Feb., 1967], No. 6634/67. Heading B3E. A pipe-bending machine comprises an arm 6 pivoted about the centre of curvature 4 of a fixed former 5 and carrying a roller 23 which engages a length of pipe 11 through the medium of a guide 26. The roller mounting 15 consists of a locating member 14 connected to a rollercarrying slider 20 by a screw 17. Sets of holes 12 allow variation of the height of the mounting in the arm to accommodate the use of different formers and fine adjustment of the height of the roller relative to the locating member, e.g. to accommodate different qualities of pipe to be bent, is achieved by rotation of the screw 17 by means of a knurled enlargement 18. A scale 24 on the enlargement 18 enables the screw to be rotated a predetermined amount with reference to a mark 16a on the locating member. The height of the roller should be such that the roller does not contact the guide 26 until it has been angularly displaced from the vertical. If many similar pipes are to be bent the height may be determined by means of a setting piece 25 secured to the guide 26 which after adjustment of the roller height is slid towards an invertible pipe-locating block 10 so that the setting piece is clear of the roller when bending begins.
