Title: Double fuze for hand grenades
IPC: F42C9/14
Filed: 1964-12-01
Abstract: 1,037,240. Fuzes for hand grenades. RHEINMETALL G.m.b.H. Dec. 1, 1964 [Dec. 18, 1963], No. 48801/64. Heading F3A. A fuze for a hand grenade, which can operate on impact or be set for delayed action, has a body 1 housing a primer 4 and a detonator 5 screwed into the body 3 of the grenade. During transport and storage, the fuze is protected by a cap 6 sealed by a ring 7 and held in position by two pins 22, which engage grooves 24 in the fuze body 1. To set the fuze for operation on impact, the cap is twisted clockwise and removed, and for delayed action the cap is twisted anti-clockwise and left on the fuze. A projection 25, Fig. 3, is aligned with a stud 26 when the cap is in the transport position. For action on impact, the fuze is provided with two mirror-image members 9, 10, Fig. 1, housed in a cylindrical cavity extending transversely of the fuze and thrust against conical bearing surfaces 13, 12 respectively by a spring 11, which surrounds a firing-pin 15 extending from the member 10 towards a primer 14 housed in the member 9. During transport the members 9, 10 are held apart by a pin 16, Fig. 3, thrust outwardly by a spring 18, but secured in the locking position by a conventional safety band 19 from which extends a grip 20 held against the body 3 of the grenade by a ring 41, removed before throwing, and by the cap 6. The delay means comprises a spring-loaded striker 28 pivoted on a pin 38, Fig. 3, and held away from a primer 32, Fig. 2, by a slide 30, Figs. 1 and 2; held against the body 1 by the band 19. The striker 28 is also secured by a bolt 39, Figs. 2 and 3, movable longitudinally on the grip 20 and held in the locking position by a spring 40. After the fuze has been set for impact action and the grenade thrown, the bolt 39 releases the striker 28 and, when the band 19 has unwound, the slide 30 drops, the striker then pierces the primer 32, which ignites a delay 33 communicating with primer 4 through a bore 34. Should the grenade be dropped accidentally after setting, flexible strips 37, Fig. 1, prevent the band unwinding. Strips 37 are of sheet metal or plastics and are attached to the fuze body at one end only. During setting for delay, a projection 35, Fig. 1, on the cap 6 pushes the slide 30 downwardly until a bend 36 in the slide frees the striker, which is still held by the bolt 39. By turning the cap in the reverse direction the slide 30 can be made to re-engage the striker. As shown in Fig. 3 a lever 43 is mounted on the grip 20. When the grenade is thrown, lever 43 is forced outwards by a spring 44 and by means of a wire 45 draws the bolt 39 out of engagement with the striker. Alternatively the grip 20 may be a doublearmed lever (not shown) tiltable longitudinally of the grenade body and having at its upper end a tongue which acts as the bolt 39.

Abstract: 1,170,422. Turret tuner switches. GENERAL ELECTRIC & ENGLISH COMPANIES Ltd., and H. B. S. BRABHAM. 2 Feb., 1968 [31 Oct., 1966], No. 49020/66. Heading H3Q. [Also in Division H1] A turret-type switch connected to a radiofrequency tuned circuit for switching inductive and/or capacitive elements comprises a drum 2 housing inductance coils (not shown) connected to stud contacts 5 arranged in axial rows to co-operate with a fixed row of strip contacts 11, the stud contacts having surfaces which in planes perpendicular to the axis of the drum are substantially concentric therewith, and the parts of the strips which engage the studs are substantially convex (as at 13) such that engagement occurs at substantially the same position along the length of the strip regardless of small variations in angular positioning of the drum 2, whereby the inductance introduced into the circuit by the switch is substantially independent of such positional variations. Each stud contact 5 is fitted into a tubular P.T.F.E. bush 8 and is elongated such that the electrical path length inside a stud does not change much with movement of the point of contact across its domed face. The ends of the strip contacts may have a coating of a gold alloy. The convex end of strip 11 may be provided by indentation (15, Fig. 3, not shown) or by contact stud (16, Fig. 4, not shown). To reduce the capacitance between adjacent studs on the drum 2 these may be made T-shaped with relatively small width in the direction of the drum axis (Fig. 5, not shown), and may be curved in this direction to provide point contact when used with a curled strip end 13 (Fig. 6, not shown). The inductance of strips 11 may be reduced by folding them into a V-shape (19, Fig. 7, not shown). The stud contacts may be fixed and the strip contacts rotatable.

A bearing assembly comprises a resilient supporting member 20 of elastically deformable material having a bore 22 and means 28 for defining together with a rigid bearing sleeve 18 of porous bearing material at least one lubricating reservoir. As shown, a rubber supporting member 20 is bonded to an outer sleeve 6. A grid of longitudinal and circumferential integral raised ribs 28 are formed on the inside surface of part 20 in bore 22 to be engaged by the outer surface of sleeve 18. On assembly, after sleeve 16 and member 20 are bonded together, they are immersed in lubricant and sleeve 18 is fitted into bore 22 to seal the reservoirs defined by ribs 28 and to entrap lubricant therein. Bore 22 is formed between shoulders 24 and 26 which help to retain sleeve 18 and also act as shaft seals. The sleeve 18 is made of porous sintered metal.

In an alternative embodiment, the blades are spaced radially outward of the posts, there being more blades than posts. The posts in this embodiment are preferably triangular in cross-section to prevent clogging of cut material passing into the reel. Selected blades may be positioned opposite the triangular shaped posts, the selected blades being of greater width to engage in longitudinal slots in the posts and to thereby act as guides for the cut fibre material.

Abstract: 1,177,190. Nuclear fuel. UNITED STATES ATOMIC ENERGY COMMISSION. 31 Oct., 1968 [8 Nov., 1967], No. 51596/68. Heading G6C. A known coated fuel particle having an outer surface consisting of a high density, smooth, carbon-containing coating is, according to the invention, provided on its outer surface with a high density, textured, carbon containing coating. The fuel particle is incorporated in a carbon matrix and the final textured coating acts sacrifically to receive the stresses arising from the particle-matrix interaction to protect the smooth coating from damage. The term "textured coating" is defined as a coating that is roughened, having surface-connected porosity, and characterized by a relatively high surface area. The term "smooth coating" is defined as a coating that is highly polished, having a non- porous surface, and characterized by a relatively low surface area. The textured coating may be an isotropic pyrolytic carbon coating. The smooth coating may be of silicon carbide or may be a thin anisotropic pyrolytic carbon coating placed over a conventional, protective, high density, isotropic, pyrolytic carbon coating, this in turn being placed over a first highly porous pyrolytic carbon coating. The fuel particles may consist of oxides, carbides or nitrides of thorium, uranium or plutonium and in a particular example given are sol-gel derived UO 2  particles. The textured coating is deposited from propane, propylene or 1À3 butudiene gas at a flow rate of from 2À0 to 3À5 cc./cm.<SP>2</SP>/min. and at a temperature of 1250 to 1300 C., the coating thickness being about 13 microns.
