Abstract: 849,133. Ignition fuze cords. ENSIGN - BICKFORD CO. July 28, 1958 [July 26, 1957], No. 24195/58. Class 9(1). Ignition fuze cord comprises a plurality of strands 2 coated with a combustible material and surrounded by a loose fitting flexible tubular casing 1 so that flame may pass freely through the casing when the strands are ignited. The strands may be made of cotton, jute, synthetic material or twisted paper. Fibre glass may also be used, but a soft fibre is preferred. The casing is preferably formed by extrusion from polyethylene. Polyvinyl chloride or polyvinylidene chloride or rubber may also be used. The combustible may be a black powder comprising potassium or sodium nitrate, charcoal and sulphur. Potassium perchlorate mixed with carbon, potassium nitrate mixed with carbon or potassium, nitrate mixed with lead oxide and silicon may also be used. The mixture together with a binder, such as nitrocellulose, starch, animal glue, wax or a synthetic resin, may be applied to the strands by dipping, spraying or by an extrusion process. After treatment, the fibres are gathered together, either in parallel or by twisting, before enclosure in the casing 1. A second envelope 3 of fibre glass, cotton, linen, rayon, nylon or wire may be braided over the casing 1. Over the envelope 3 a jacket 4 of an organic plastic material or rubber is formed. Wax, glue or polyethylene are alternatives for the jacket 4. The ignition cord may be used to connect two lengths of detonating fuze cord 5, Fig. 3. A length TL of the ignition cord secured in a blasting cap 6 at each end is bound by tapes 7 to the free ends of the cord 5 to cause a delay in the firing of a charge connected to one of the cords 5, the delay depending on the extent of the ignition cord. A connecting sleeve may be used to secure the ends of the cord 5 to the cord TL. One end of the cord, Fig. 7, may extend into a fitting 10 having an axial recess 11 filled with a delay composition, e.g. red lead and silicon. The terminal fitting is coloured or marked to indicate the burning time of the delay and the fitting is inserted into a blasting cap 6. Fig. 9 shows an arrangement in which the ignition cord is used to connect explosives charges 13, 14, e.g. for operating positions, to an ignition source 15, which may be a percussively or electrically operated primer. A hollow T-shaped connector 16 having an internal stop 17 receives the free ends of cords TL.

Abstract: 1,182,145. Endless conveyers. DIAMOND INTERNATIONAL CORP. 26 May, 1967 [23 Sept., 1966], No. 24688/67. Headings B8A and B8S. [Also in Division A2] Iced lolly sticks 10 in a hopper 18, fall into recesses 22 of an endless conveyer chain 21, but if any recesses remain unfilled, they are fed with a stick from a reservoir shoot 30. The conveyer operates in cycles each of which consists of a part (a) which supplies a number of side-by-side discharge shoots 60 at a station 50, and a part (b) which is used to replenish the supply of sticks in the shoot 30. Discharge from the conveyer into the shoots 60 is effected simultaneously by rotation of a roller 56. The sticks are thereby rotated (Fig. 11, not shown) out of the conveyer recesses 22, engage a member (57), (Fig. 11, not shown), and are then moved in a direction parallel to their own axes into shoots 60. The shoots 60 feed the sticks 10 into shoots (61) (Fig. 12, not shown), which are then swung into a vertical position in alignment with plungers 65 carried by a member 66. Downward movement of the latter drives the sticks 10 into the lollies (not shown). The transition to part (b) of the cycle is determined by the position of a cam 32 (Fig. 3), a raised part of which lifts a member 34 to prevent a sticks 10 from being conveyed beyond the base of the shoot 30. A projection 41 of a second cam 38 then engages beneath the stick 10 and drives it upwards into the shoot 30 (Fig. 10). When the shoot 30 contains more than a predetermined number of sticks 10 a member 43 is engaged by the top stick of the stack in the shoot, and deflects a member 46 via a cable 44. The member 46 is moved into a position in which it knocks off oncoming sticks from the conveyer. Decrease in level of the sticks in the shoot 30 operates a microswitch 49 so as to cause an alarm to sound. The hopper 18 is fed from an upper hopper Section 15 which has provision for receiving a carton 11 of sticks 10. An oscillating plate 16 tends to prevent jamming of sticks in the hopper 18 and defines a gap between the hopper sections 15 and 18.

A winch 19 enables a fuel element assembly 2 to be lifted into a rotatable magazine 18 having two compartments. In a fuelling operation one of the magazine compartments is initially filled with a new fuel element assembly 2 obtained from a tube 24. The nose 17 is sealed to an extension 11 after opening the valve 14, the valve 15 is opened and the irradiated fuel element assembly in the tube 3 is raised into the empty magazine compartment. The magazine 18 is rotated and the new fuel element assembly is lowered into the tube. Finally, the irradiated fuel element assembly is deposited in a tube 24. The individual bundles 7 of an assembly 2 may be shuffled in a machine 25 centrally pivoted about a horizontal axis. A hoist 29 enables fuel element assemblies to be transferred between the machine 25 and tubes 24 and between the machine 25 and storage racks 26 for irradiated bundles 7 situated in a pond extension 27. In a modification (not shown), the valves 14 are replaced by plugs and the nose 17 has a closure valve. The plugs are retained by latches in the extensions 11 and a plug is released, after sealing the nose 17 to the extension, by increasing the pressure in the casing 16 so that it exceeds the pressure in the reactor.
