Title: Improvements in or relating to strainers for liquids
IPC: B01D35/06
Filed: 1950-05-09
Abstract: 681,306. Strainers. WARDLE, J.. and WARNIC ENGINEERING CO., Ltd. April 24, 1951 [May 9, 1950], No. 11537/50. Class 46. A container of the kind in which all or part of the straining means is cleaned by reverse flow of liquid comprises a rotatable hollow straining cylinder, a tubular member extending into the cylinder and a piston device sliding within the cylinder the arrangement being such that the piston may be displaced to produce a reverse flow of liquid through part of the straining means in turn. Liquid entering at 2, Fig. 1, surrounds and passes through a cylindrical filtering medium 11 arranged on a cylinder- 4 having external ribs 5, Fig. 2, and then passes through all but four of holes 9, Fig. 2, in the cylinder 4 to cut-away parts of a flange 16, Fig. 3, on a tubular member 15 and thence into an annular space 12, Fig. 1, between the tubular member and the cylinder. It leaves by an outlet 3. The remaining liquid passes through the remaining holes 9 into and through ports 18, Figs 1 and 2, formed in the flange 16 of the tubular member 15. to a region 13, Fig. 1. From here it flows between the member 15 and a central rod 20 and reaches the filtered-liquid space 12 through ports 19. When it is desired to clean part of the medium 11 a piston 25 is raised by a handle 21 and the rod 20; during the first part of the movement a boss 24 on the piston enters the bore of the tubular member 15 thus cutting off the flow of liquid from the space 13 to the outlet. Thereafter the liquid remaining in this space is forced upwards through the ports 18, and out through the holes 9 then registering with the ports 18, and impinges on a deflector sleeve 10 mounted on the ribs 5. It then flows upwardly and downwardly in the four grooves 6a, Fig. 2, and finally out through the medium 11. The tubular member 15 is immovably secured by a plug 17 in a casing cover 1 and the cylinder 4 rests upon parts of the flange 16 of the e member 15 by means of a shoulder 14, Fig. 1. To charge the part of the medium 11 to be backwashed the cylinder 4 may be rotated about the e flange 16 by means of the handle 21 acting through an extension 26 which holds the piston 25 in place on the rod 20, is of hexagonal cross-section, and engages in a hexagonal hole in a plate 27 attached to the bottom of the cylinder. , A fixed scraper 29, Fig. 2, bears against the outside of the medium 11. In the modification of Fig. 6, the plug 17 is extended and on it is mounted a magnetic filter unit 35 past which the liquid must flow to the outlet 33. In Fig. 7 a casting 38 is closed by a removable cover plate 41 having an apertured depending wall 47 forming with the casting an annular filtrate space 43. The filter cylinder 44 is removably held as before by a flange on the tubular member 45 in this case against the lower end plate of a magnetic restraining unit 46 to which liquid gains access through slots 47. In either case the magnetic filter may be replaced or supplemented by a fine filter of fabric felt or other material.

Title: Improvements in or relating to means for preventing or reducing the escape of high frequency energy
IPC: H01P1/202
Filed: 1941-09-12
Abstract: 562,674. Wireless signalling apparatus. COLLARD, J. Sept. 12, 1941, Nos. 11693/41 and 748/42. [Class 40 (v)] In screened highfrequency electrical apparatus,undesired radiation through apertures and discontinuities in the screen is prevented by the introduction of quarter-wavelength sections at the discontinuities. Fig. 1 shows a pair of coaxial adjusting shafts 9, 10 passing through an aperture 4 in a screen 3 enclosing high-frequency apparatus. The shafts are each provided with three quarter-wave sections 11-13 and 14-16 respectively contained within a sleeve-like extension of the screen 3. The quarter-wave sections are closed at one end and present high impedances in series with the leakage path. This arrangement simultaneously prevents radiation through the aperture and propagation of energy along the shafts. A similar arrangement for a current lead passing through an aperture is also described. Fig. 2 shows the invention applied to a screen with a removable lid L which rests between quarterwave flanges r1, r2 and r3 on a base B. In this case, the space between the flanges may be filled with dielectric. Other modifications are described having a greater number of flanges which may be relatively displaced either radially or axially. In Fig. 3, the leakage path between a lid 18 and box 19 consists in the three quarterwave paths 20, 21 and 22.

Title: Improvements in generating power, and more particularly in its application in operating prime movers
IPC: F02G3/00
Filed: 1936-04-25
Abstract: <PICT:0474291/III/1> <PICT:0474291/III/2> <PICT:0474291/III/3> A fuel supplied from a storage tank and consisting of hydrogen mixed with oxygen, air or steam separately or in combination is burnt in a combustion chamber, and water, steam, or the products of combustion are passed through a pipe situated in the combustion chamber, or in a chamber in communication therewith, but not open to the combustion gases, whereby the fluid passing through the pipe is superheated or dissociated thus producing a working fluid or fuel which is admitted either into the storage tank or directly into the combustion chamber to be used in an engine, turbine or boiler for the production of power.  In a modification, a mixture of hydrocarbon and air is burnt in the combustion chamber of an internal-combustion engine, and water or steam is passed through the pipe to produce hydrogen and oxygen which are admitted to the tank and used as required for the production of power.  The pipe is preferably made of nickel-chromium-tungsten steel.  Hydrogen and oxygen from a tank 4, Fig. 1, are admitted by an inlet valve 5 to a combustion chamber 2 and after compression by a piston 6 are exploded by means of a sparking-plug 5B.  The exhaust water vapour is discharged through an outlet 5A connected to a pipe 1 passing through the combustion chamber and is then returned to the tank 4; a baffle 1A spreads the vapour into contact with the inside surface of the pipe 1.  Water, steam, or the exhaust water vapour may be superheated before entering the pipe 1, by passing through p  a pipe 13 situated in a chamber communicating with the combustion chamber 2 by a narrow passage which may be closed except during the combustion stroke.  Steam from the cylinder cooling-jacket may be injected into the pipe 1.  Fig. 5 shows a steam generator in which hydrogen and oxygen from a tank 4 are admitted through a valve 5 to a combustion space where they are exploded by means of a sparking-plug 5B.  The superheated steam thus produced passes through an outlet 5A to drive a steam engine or turbine.  Steam which may be from the exhaust of the engine &c. is passed through a pipe 1 situated in the combustion space and is dissociated and returned to the tank 4.  In a modified form of steam generator, hydrogen and oxygen from a tank 4, Fig. 7, are separated by diffusion through a porous pipe 14 and pass to a burner 2A situated in a combustion space 2.  Steam which may be from the exhaust of the engine is injected into the flame, and part of the combustion products pass through a dissociating pipe 1 and then return to the tank.  In a further modification, hydrogen and oxygen from a tank pass by separate pipes to a burner in a combustion chamber from which a pipe passes through a water space; steam thus generated or from the exhaust of an engine driven by the steam is injected into the flame, and the products of combustion pass into an electrolysis plant, the gases from which enter separate compartments in the tank.
