Abstract: 131,025. Kennedy, D. March 25, 1918. Projectile fuses.-Relates to percussion fuses of the kind comprising a sliding firing-pin carrier, a detonating- cap holder, a spring tending to keep these members apart, and a safety-bolt interposed between them until after the projectile has been discharged. According to the invention, the firing-pin A is lengthened to receive a guide-piece C which, on the escape of the safety-bolt E, slides along the pin A into contact with the detonator-holder F under the action of a spring D, which spring also serves to keep the firing-pin away from the detonator until impact occurs. A detachable member K, which is adapted to connect the fuse to the projectile, supports the detonator-holder F in the fuse-body. A ball L is provided, in a known manner, to ensure action when impact in any direction occurs. In a modification, the guide-piece C has an annular recess to accommodate the spring D. A device E<1> which controls the safety-bolt E is described in Specification 130,629.

E. ; 111, Woburn Street, West Medford, both in Massachusetts, U.S.A.) Feb. 23, 1932, No. 5400. Convention date, Sept. 4, 1931. [Class 118 (ii).] Apparatus for recording distances or depths measured by the echo method comprises a longitudinally-movable waxed recording paper and a transversely-moving element, normally out of contact with the paper, adapted to scrape off the wax when the echo is received, the marks so made being closely spaced to form a continuous contour. A power-driven shaft 8 is connected by gearing to a shaft carrying an arm 15, at the end of which is secured an electromagnet 29 having an armature 32, Fig. 8, attached by a spring 33 to the magnetic core 27. The armature has fixed to it a stylus 36 which is normally held out of contact with the record strip by the magnet 29 but is prevented from touching the surface of the core by a stud 90 of nonmagnetic material. A sound is emitted when the arm 15 is in a predetermined position, and on the receipt of the echo the current through the magnet 29 is interrupted, the spring 33 then forcing the stylus into contact with the record strip. This strip is comprised of coloured paper coated with wax, the mark being formed by the stylus removing the wax and revealing the coloured surface. The circuit connections are shown in Fig. 9. The magnet 29 is normally supplied through the thermionic valve 107 conductively coupled to,the preceding valve, the supply being interrupted on the receipt of the echo at the microphone. In place of the valve 107, two such valves may be arranged in parallel, one connected to the recorder described above and the other to an indicator of the neon-tube type. When the end of the record strip is reached an alarm 108 is energized by a contact 109 passing through a perforation in the strip and contacting with a metallic surface 3 over which the record strip slides.

Title: Improvements in or relating to filters for liquids
Inventor: WOOD GEORGE
IPC: F01M11/03
Filed: 1955-02-23
Abstract: 789,323. Liquid filters. VICKERS-ARMSTRONG (ENGINEERS), Ltd. Feb. 15, 1956 [Feb. 23, 1955], No. 5487/55. Class 46. A straining cartridge, for use with filters for oil &c. and providing a hollow interior or core, comprises a pile of straining elements each consisting of a ring-like member made up of a pair of annular casings spaced apart axially and formed with perforated faces between which and the inner and outer walls of the casing felt &c. is accommodated, the elements being assembled coaxially, face to face with spacing means between the faces of adjacent elements to provide a laminated cartridge which, when positioned in the filter body defines an encircling outer chamber and an inner chamber constituted by the core so that oil &c. can be filtered while flowing from one chamber into the spaces between adjacent elements, thence through the filtering medium and into the other chamber. Liquid to be filtered enters a casing 1 and flows to the exterior of a stack of filter elements 14 the hollow core of which communicates with an outlet 4 in a cover 3 for the casing 1. The elements 14 are separated from one another by distance pieces 32, Fig. 3, having radial arms 33 providing between them sector shaped recesses 34, into which the liquid to be filtered flows. Four of the arms are extended to receive holding rods 38 which prevent rotation of the distance pieces 32. Each element (shown exploded in Fig. 4) consists of a keeper ring 22 having an internal rib 23 to support upper and lower annuli 24 separated by distance pieces 31. The outer parts of the annuli are perforated at 25 and each annulus has a stepped central portion 26. Beside the step lies a ring 29 of felt or other filter material which is held against the perforated part of the adjacent annulus 24 by a recessed annular member 28. Rods 17 passing through lugs 30 on the annuli 24 are adapted through nuts 18 to clamp the elements and distance pieces 32 together. The rods 17 are mounted in end covers 15, 16 rotatably mounted in a lower support 13 and the cover 3 and keyed to a shaft 6 rotatable by a handle 8 to make the arms 33 scrape the surfaces of the adjacent elements 14. The distance pieces 32 may, however, be mounted non-rotatably in respect of the elements 14 and cleaning be effected by back-washing. For this purpose the inside chamber 35 communicates through the elements with a vertical nozzle 41 held closely against the outer surface of the elements 14 by a spring- pressed bar 43 and of a width to mask a single sector 34. The nozzle leads to a valved outlet 45, 46, the pressure in the inside chamber being sufficiently above that in the nozzle to compel flow therethrough. The pile of elements is rotated continuously or step by step to bring every sector 33 opposite the nozzle 41. The nozzle may carry one or more scrapers 48. Specification 564,032 is referred to.

Abstract: 525,360. Directive wireless signalling. DAVIES, G. L. Feb. 20, 1939, No. 5529. [Class 40 (v)] The shape of a landing- beam of constant fieldintensity, radiated by an antenna array, is adjusted by varying the vertical spacing, or the height, of the radiating elements. The path is a parabola of the form X<SP>k</SP> = ay, and the invention discloses means for altering the value of the " family " index K. The array may consist of three horizontal radiators all energized in phase, as shown in Fig. 6 ; or the centre arc may be energized in phase-opposition to the other two, as in Fig. 7. In both cases, the shape of the radiated beam is adjusted by varying the vertical spacing between the uppermost and lowermost radiator. Only two radiators may be used, both energized in phase. If the two are energized in phase-opposition, the required effect is secured by uniformly varying the height of both radiators. The horizontal aerials may be replaced by vertical ones, arranged end to end.
