Title: Improvements in or relating to shells
IPC: F42B10/56
Filed: 1920-12-08
Abstract: 181,037. V.M.L. Experimental, Ltd., (formerly M. L. Experimental, Ltd.), and Lucas, O. D. Dec. 8, 1920. Pyrotechnic devices.-Relates to shells of the kind having separate ends attached to a tubular body and intended to be discharged from a smooth-bore gun on the ground, for signalling to or guiding aircraft by means of smoke-emitting devices or parachute lights contained within the shell and ejected through one end thereof by an explosive charge. According to the invention, the base A, Fig. 8, or front end B, Figs. 7 and 9, whichever is forced open by the expelling charge, is attached to the tubular body C by shear pins b which may form a. bayonet-joint; and the other end-piece of the shell is fastened by pressing or spinning the edge of the tubular body into a groove in that endpiece. As shown in Fig. 8, the tubular body C contains a flare C<1> with a parachute B<1> behind an expelling charge D fired by a Bickford time-fuse E ignited by a cap h<2> when a pin h<2>X is sheared and the cap sets back on to a striker H by inertia. on the discharge of the shell from a gun after the removal of a safety pin H‹. The flare is ignited by a quick-match started by the expelling charge. The fuze-body B' is separated from the front plug B of the shell by a felt washer B<6>. As shown in Fig. 7, the parachute flare is in the front part of the shell, and the fuze E for firing the expelling charge D is ignited by the cap h<2>, in the base of the shell under the combined action of inertia, which shears a pin h<2x>, and the forward thrust of a striker H with the gas-check F by the pressure of the propellent gases when the small shell is discharged after the removal of a safety pin F‹. In other modifications, a percussion cap in the base of the shell is fired by a striker normally held at safe by a shear-pin, but thrust forward by the pressure of the propellent gases on its exposed rear end. In the form shown in Fig. 9, the shell contains stars K arranged in tubes K<2> and ignited by a quickmatch K<1> before they are expelled by a charge D‹ at the bottom of each tube. The quick-match is set alight by a compressed powder-pellet F<2> ignited directly by the flash from the propellent gases. The front end B of the shell is a paper disc with a square-shaped projection B<x> in the centre to facilitate placing it in position. In a modification, the tubes K<2> are not used, and a single expelling charge ejects all the stars which are separated by primed paper discs. The shells. are made up to correct weight by the addition of small shot, for example as at C<5>, Fig. 9.

Abstract: 846,278. Making turbine and like blades; removing metal by arc-erosion. ROLLS-ROYCE Ltd. Nov. 20, 1957 [Nov. 20, 1956], No. 35521/56. Classes 83 (2) and 83 (4). [Also in Group XXXVI] Axial passages are formed in a turbine or compressor blade 10 by electric arc-erosion using a hollow electrode 36 of the cross-section required for the passages and through which flows an electrolytic bathing liquid, the blade and electrode being reciprocated relatively to each other during the erosion. The passages are preferably of lenticular cross - section arranged as described ih Specification 846,277. Alternatively, the holes may be of circular cross-section and are deformed into lenticular cross-section during extrusion of the blank as described in Specification 826,498. The blade 10 of nickel chrome alloy is clamped to a vertical shaft 23 having rack teeth which cause it to be fed downwardly by means of gearing 25, 29, 30, driven from an electric motor 31 controlled by a speed control 32. A counterweight 34 attached to a cord 33 is used to steady the blade. Electrode drill 36 is mounted in a holder 37 and supported by guide bushes 40a which are removed successively as the blade descends; the electrode is reciprocated by a crank or eccentric 46 driven by motor 47. An electrolyte solution of sodium silicate in equal up to six parts of water, preferably three or four parts of water, is fed to the electrode by compressed-air through a pipe 43 from a tank 42. A direct current or a combined alternating current and direct current is supplied through leads 49, 50 to the electrode and blade. In one embodiment this current may be of 6-24 volts at 100 amperes, and in another embodiment the current is of 10 volts at 10 amperes. In another embodiment, Fig. 8, for forming twisted passages in the blade 10, the electrode is of helical form and is rotated during the downward feed of the blade 10 by means of a slotted bar 77 adjustably clamped at 77b to the blade holder 70 which is moved downwardly by a lead screw 72 driven by a motor 75. Slot 77c engages a pin 78a on a horizontally movable rack 78 which drives, through a compound pinion 79, 80, Fig. 7 (not shown), incorporating a clutch, a second rack 81 meshing with a pinion 82 on the electrode holder. The latter is reciprocated by an eccentric 84 driven by an electric motor. The blade holder 70 may be reciprocated horizontally by an eccentric 98 driven by an air motor 95. When the bar 77 is clamped in a vertical position straight passages are drilled. Electrolytic solution is supplied to the electrode under high pressure from a container 89, Fig. 7 (not shown); it is collected in a tray 93 having a drain pipe 93a. In a modification of the first embodiment, Fig. 6 (not shown), the electrode is rotated by a pinion having a pin engaging in a helical cam groove in a vertical shaft attached to the blade holder. The blades may be for a rotor or stator.

Abstract: 1,118,051. Bobbin storage apparatus; donning & doffing bobbins. JAMES MACKIE & SONS Ltd. 26 Aug., 1965 [2 Sept., 1964], No. 35960/64. Headings DID and D1F. [Also in Division F2] Bobbins are doffed in turn from the spindles of a spinning &C., frame and placed in aligned positions without interlocking with one another on a storage device which is body transportable to a position apart from the frame, and empty bobbins are removed from the storage device and placed on the empty spindles. The device comprises a drum 2, having compartments 10, (or bobbin receivers, e.g. rods) each containing empty bobbins stacked one on top of the other. A filled bobbin is put in at the lower end of the of the compartments causing the uppermost A filled bobbin is putin at the lower end of one compartment, and causing the drum to be indexed so that bobbins are inserted into and removed from each compartment in turn. A full bobbin is placed in a shoot 14 to fall on a spigot 16; its weight rocks a pivoted arm 26 to operate a valve 34 through a link 30 and admit pressura-fluid to a cylinder 36 to raise a piston rod 38 and lift the spigot arm 18. A roller 40 on the arm rides over a cam surface 43 so that the bobbin on the spigot is aligned with a compartment 10. Further movement of the rod 38 causes the bobbin to enter the compartment, to raise all the bobbins and eject the uppermost one on to a spigot 46. A cylinder 48 is now energized to lift the spigot so that the bobbin falls into a shoot 50 to pass to a donning apparatus e.g. that of Specification 1,118,052. The drum so that a spring 71 can swing these members back to their original 'positions ready to receive another bobbin. The device has wheels, and a male member 78 which can be inserted in a socket (76 Fig. 5, not shown) on a tow-bar attached to a travelling doffing &c., apparatus. So that when this apparatus stops at a spindle it is not shifted by the momentum of the drum and its contents, a piston with a brake pad (90) is linked to an arm pivoted to the bar, so that the pad is forced against a fixed part when the device tends to move relatively to the apparatus, the brake may be released by a handle (96). More than one bobbin can be inserted at a time; the drum may be indexed only after each compartment has received a number of filled bobbins e.g. after all the bobbins have been changed. The axis of the drum may be horizontal and each compartment may hold only two bobbins. The insertion device may be indexed instead of the drum. The device may be operated pneumatically, hydraulically or electrically.
