Patent GB-156995-A (GB)
Title: An improved process and apparatus for the electrical transference of designs in the textile arts
IPC: D03C19/00
Filed: 1920-01-24
Abstract: 156,995. Marks, E. C. R., (Oesterreische Siemens - Schuckertwerke Ges., and Regal- Patente Ges.). Jan. 24, 1920. Jacquards ; cards and the like, punching. - In electrically operated jacquard and card-punching machines, the needles controlling lifting-wires are divided electrically into two groups corresponding to the electrically conducting and non-conducting parts of the pattern and the selection within these groups for the tyings or bindings is effected mechanically by cards &c. either for both groups simultaneously or for one after the other. The electrical selection is effected in the known manner by means of a rotary pattern surface, step-operated feelers connected to contact bars, and step-operated brushes connecting the bars to contacts for the individual solenoids s of which the cores g are initially pressed out into the position shown by mechanically-operated wires y so that they block holes x in tubes. Auxiliary needles h are initially raised against the action of springs z by a plate o acting on collars w on the needles, and when the plate descends the needles h corresponding to energized solenoids s pass through the holes x, the cores g of these solenoids being withdrawn to the right, while the needles corresponding to the other solenoids are held up by the cores. The needles n for controlling the lifting-wires t are thus divided into two groups which are acted upon respectively by cards i, k cut to control the bindings for the ground and figure. The cards are so perforated that each does not interfere with the other. Separate cards acting in succession may otherwise be used, or one card with the bindings cut in alternate rows. A constructional form of apparatus is described in which the various parts are operated by cams, rods, and levers from a rotating shaft and the pattern barrel is rotated by ratchet and worm gearing.

Title: Improvements in or relating to x-ray apparatus
IPC: G02B27/02
Filed: 1952-02-01
Abstract: 695,773. X-ray apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 1, 1952 [March 22, 1951], No. 2733/52. Class 98 (i). The apparatus comprises an electronic image intensifier tube having a fluorescent screen, an electron optical system energized by light from the screen, means for projecting an electron image of the light-field of the screen to produce a contracted light-image on an output screen and an optical system for viewing the lightimage, wherein the optical system comprises a roof-mirror, a magnifying lens system, means for supporting the roof-mirror and lens system in position to project an image appearing on the output screen to one side of the axis along which the electron image is projected, and means for adjusting the roof-mirror and lens system to vary the angle of the rays reflected by the roofmirror relative to the axis of projection of the electron image. An X-ray tube below a patient-supporting table (not shown) produces an image on the input screen of an electronic image intensifier. The X-ray tube and image intensifier may be mounted to move along the table, which may be tiltable. A much brighter, but smaller image is formed at the output screen 9 of the image intensifier 5. A housing 6 enclosing the image intensifier 5 is apertured opposite screen 9 and supports a disc 13 having an annular groove in which a ring 15 is rotatable. Disc 13 is apertured to support a lens 14. A pair of mirrors 19 at right-angles are mounted on an axle 18 carried in brackets 17 on ring 15. A gear-wheel 21 fast with axle 18 is geared to a wheel 22 freely mounted on the axle and fast with a bracket 23 carrying a lens 25. The gearing is such that on moving bracket 23 through a given angle, mirrors 19 move through half that angle, so that an observer sees the image through lenses 14, 25 and by reflection by mirrors 19. The optical system is such that the image on screen 9, which is reversed laterally and vertically with respect to the original image on the input screen, is seen as an unreversed image equal or greater in size to the original image and of greater brightness. The whole system can be rotated about the axis of the intensifier, and the exit pupil of the optical system is large enough to enable the observer to view the image with both eyes. Clamping means may be included to hold the parts in any required position. Specification 662,569 is referred to.

Title: Improvements in or relating to wind direction finding devices of the pyrotechnic smoke type
IPC: F42B12/48
Filed: 1934-01-26
Abstract: 432,438. Smoke-producing and windindicating cartridges. RANKIN, F., 14, Douglas Crescent, Edinburgh, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Jan. 26, 1934, No. 2807. [Class 9 (ii)] A smoke-producing cartridge adapted to be discharged from a firearm from an aircraft downwards to the ground, comprises in addition to the smoke-producing compositon another composition adapted to be ignited with the smoke-producing composition when the cartridge is discharged and adapted to remain incandescent for a period of time sufficient to enable it to reignite the smoke-producing composition if the latter is extinguished on landing. As shown in Fig. 1, the cartridge consists of a metal tube 2 filled with smokeproducing composition 12 and closed by a cap 1. The base 3 of the cartridge has a central hole closed by a thin lead foil 8, and between this base and the smoke-producing composition 12, there is a washer 4 with a central hole containing one or two pieces of quickmatch 9, a star washer 5 filled with gunpowder 10, and a tinned steel wire cage 6 containing the incandescing composition. This may be a mixture of equal parts of silicon and saltpetre baked hard. The silicon may be replaced by ferrosilicon, calcium silicide, or zirconium; and the saltpetre may be replaced by sodium nitrate, potassium perchlorate, or potassium permanganate. This cartridge may be discharged like a projectile from a propellent cartridge containing a small propellent charge in a recess in its base, the smoke producing cartridge being normally held in the propeller cartridge by a top wad of felt covered with sealing wax. The flash from the propellent charge melts the lead foil 8 and ignites the smoke-producing cartridge.

Abstract: 668,546. Endless-belt conveyers. ZAPP, P. E., BORGGRAFE, A., and EICKHOFF, A., (trading as EICKHOFF, GEB.). Jan. 30, 1950. [Feb. 5, 1949] No.3240/49. Class 78 (i). The driving head of a belt conveyer includes a detachable unit or units consisting of a driving motor and gearing and a support for one or more belt driving drums, and is characterized in that each drum driving shaft of the gearing is adapted directly to engage the hub of a belt driving drum. A housing 3 for the gearing is detachably secured to a bed plate 1 and the output shafts 10 and 11 are driven oppositely at equal speeds. A plate 2 also secured detachably to the bed plate 1 is provided with two holes 22 into which are bolted circular plates 21 housing bearings 20 for one end of a pair of drums 4, 5. The other ends of the drums are directly coupled to the shafts 10, 11 by means of splines on the shafts and in the hubs 14 of the drums, so that each drum with its gearing is supported by three bearings only. The hubs 14 are detachably secured to the bodies of the drums as are also the hubs 16, 17 at the ends adjacent the plate 2. The holes 22 in plate 2 are of larger diameter than the drums so that a drum may be removed by unbolting the plate 21. A sealing washer 24 in a recess in each of the hubs 14 prevents dirt from entering the internal splines. When the housing 3 is removed, the adjacent ends of the drums may rest in cradles, e.g. in a plate 25, the bearings 20 being self-aligning for this purpose.
