IPC: F42C9/10
Abstract: 105,587. Gilmartin, M. W. April 12, 1916. Projectiles; projectile fuses.-Consists in a projectile having explosive charges within the base and nose, and having a time-fuse which is adapted to fire the said charges and is itself adapted to be ignited directly from the propellant charge in the gun. The shell shown in Fig. 1 has the body portion A charged with balls 10 packed in an explosive. The nose portion 31 contains balls 65 embedded in meal powder and shellac, and the chamber in the base C contains powder 28. The screwed-on base has an annular tapered groove into which a projection 17 on the end of the body fits, so as to prevent separation of the base and body when the shell explodes. The driving-band 20 is screwed to the base C by a single heavy thread, and partly overlaps an annular channel 18 in the base. The fuse comprises a plate 42 having an annular timing-channel 53, which leads to a central tube 36 communicating at the forward end with the nose charge through a hole 66, and opening at the rear into the base chamber. A rotatable graduated ring 49 is mounted on the plate 42, a catch coacting with rachet-teeth being suitably interposed, and between the parts 42, 49 a thin perforable diaphragm 50 is fixed. The ring 49 carries a pin 59 which can be screwed in so as to pierce the diaphragm 50 and thus open communication between any selected point in the channel 53 and a passage 58 leading through the fixed tip 47 to an inner longitudinal tube 37. All the passages contain quick-burning powder. The rear end of the tube 37 connects with a bore in the base of the shell, the bore being packed with highly-compressed meal powder which starts the ignition of the fuse when the shell is fired. The arrangement of the fuse, as described, is such that the charges in the nose and base are fired in quick succession. In the modification shown in Fig. 5, a powder charge 75 is contained in a carton 73, the base 76 of which has a timing-channel 86 leading to the charge. Over this is a plate 84 which can be rotated by means of a longitudinal tube 83 connected thereto, on which tube is mounted a graduated tip 94, carrying a spring catch 95. The plate 84 has a perforation 85 through which a flash can pass from the igniting-channel 90 to any selected point of the timing-channel When the charge 75 is fired, a flash passes through a tube 77, perforated at 93 and 92 and containing quick-burning powder, to the nose charge. A percussion fuse 74 is provided in the carton 73. The invention is applicable to high-explosive shells.

Title: Improvements in or relating to tape handling apparatus
Inventor: SKINNER PETER
IPC: G11B15/56
Filed: 1962-03-20
Abstract: 963,927. Random tape storage. DECCA Ltd. March 14,1963 [March 20, 1962], No. 10667/62. Heading G5R. A random storage bin for magnetic tape comprises two parallel sheets of glass with a light source and diffusing screen on one side and a number of photo-cells on the other with means to restrict the light reaching the photo-cells to rays having a limited angular deviation to the normal of the sheets. As in Fig. 3 two sheets of glass 30 and 31 usually rough cast to prevent the tape from sticking are separated by walls 32 at a distance slightly greater than the tape width to form a bin. The tape is fed vertically into the bin and lies in a series of loose loops. In order to measure the amount of tape in the bin light is passed from lamps 34 through diffusing screen 33 to photocells 37. For maximum sensitivity the light rays reaching the photo-cells must be restricted in direction to small angular deviations from the normal to sheets 30 and 31 since the planar surface of the tape is always normal to the sheets. In order to effect this a honeycomb structure 36, with a plurality of hexagonal apertures normal to sheet 30 is arranged between sheet 30 and photo-cells 37. The internal surfaces of the honeycomb apertures are blackened to minimise light reflections. The signals from photo-cells 37 are chopped and compared with light which reaches photo-cell 39 without passing through the bin to give a measure of the amount of tape present. Other methods of restricting the direction of the light rays are described. Specifications 909,347 and 963,926 are referred to.

Abstract: 980,477. Filling incandescent electric lamp bulbs with gas; discharge apparatus. FABRIQUES REUNIES DE LAMPES ELECTRIQUES S.A. March 19, 1963 [March 22, 1962], No. 10826/63. Headings HID and H1F. A method of filling an incandescent lamp bulb or discharge tube with gas comprises flushing the interior with inert gas, e.g. nitrogen, at above atmospheric pressure, introducing into the envelope during flushing a quantity of inert rare gas, condensing the rare gas on a cooled portion of the envelope wall and sealing the envelope. Cooling may be effected by a bath of liquid nitrogen and the two gases may be introduced into the envelope by means of a hollow needle having two channels. In the form shown, a tubular envelope 12 sealed at one end is supported by a bracket 13 with the lower end immersed in a bath 29 of liquid nitrogen. The filament 17 extends between metal strips 10, 11 connected to the lead-in wires 16, 19, one of the strips 10 being embedded in the seal at the lower end, and the other 11 being held on a support 14. Flushing gas is introduced through a hollow needle 18 having concentric channels and after flushing the flow of gas is maintained while the gas to form the main part of the filling is introduced through the second channel of the needle and condenses at the lower end. The tube is then sealed off. Needles having two side-by-side passages may be used.

A loading device, for instance for ships, comprises two cargo booms each operated by means of at least a winch controlled hanger rope and a similar guy rope wherein the electric motors of the winches have control circuits so interlinked that during raising, lowering or slewing overloading of the guy ropes is prevented. Preferably the two booms are connected by a winch-operated belly guy, the control circuit for the motor thereof being interlinked with the other control circuits in such a way that it is switched off when the booms slew in the same direction, operates when they slew together, and is allowed to pay out under brake control when the booms slew apart. Control of the belly guy is not, however, essential as a tension measuring device can be placed in the rope and this measure used to control the hanger and guy winches. An electric slipping clutch may be used between the belly-guy drive and the winch drum. Various circuits for the interconnection of the controls are shown diagramatically and a common compound switching device is mentioned.

Title: Improvements in or relating to grabs
IPC: B66C3/08
Filed: 1927-04-23
Abstract: 291,204. Page, M. W. Flood-, and Westwood & Co., Ltd., J. April 23, 1927. Grab-buckets.-Ralates to single-chain grabs in which a button 9 on the chain co-operates with catches 15 on the grab-head to lift the grab off the ring 7 on which it is suspended for discharging by hooks 10 pivoted on pins 11 moving in slots in the grab-head. The hooks 10 are connected directly with the catches 15 to move them into and out of the path of the button 9. In the arrangement shown, the hooks 10 (shown separately in Fig. 9) move vertically in guides 13 in the grab-head, and are slotted horizontally at 14 to engage and pivot on the pins 11 which move in inclined slots 12 in the grab-head. The catches 15 (shown separately in Fig. 10) are pivoted on the pins 11 in the bifurcated lower end of each hook, so as to move laterally when the hooks move vertically in the guide 12. In the position shown in Fig. 3, the closed grab is supported on the chain, the hooks are at their lowest position in the grab-head with the pins on the outer end of the slots, the catches 15 are withdrawn from the slots 16 in the chain guide, and the hooks 10 are turned inwardly by their own weight to engage the ring 7. When the grab is suspended on the ring and the chain is payed out, the hooks 10 come to the top of the guides 13 and bring the catches 15 into the path of the button 9. When the grab is nearly full open the button 9 passes below the catches as shown in Fig. 7, and the catches return by gravity so that the grab can be lifted off the ring by hauling-in the chain. In this position of the mechanism the hooks 10 fall outward's when free of the ring. On lowering the open grab to the ground, the button 9 leaves the catches, the hooks fall in the guides 13 and on hauling-in, the grab closes and the parts are in the original position. When the button is passing below the catches, as shown in Fig. 7, weighted or spring-urged members 19 pivoted at 20 in the catches bear upon the back of each hook, and prevent the hooks becoming disengaged from the ring before the button is clear of the catches.
