Title: Improvements in shell fuzes
IPC: F42C1/06
Filed: 1940-07-01
Abstract: 548,039. Shell fuzes. TURNER, G. F. B., and REDGRAVE, K. July 1, 1940. No.11099. [Class 9(i)] A projectile fuze is. fitted with two firing devices, one adapted for actuation by direct impact, the other operated by graze action at low angles of trajectory, means being provided for interaction between the two devices. As shown, the main (impact) detonator D is fired by a pin 35 which is driven in by a plunger 7. The graze detonator 17, which co-operates with a fixed pin 20, is carried by an inertia-actuated plug E. The plunger 7 is threaded through a block I mounted in the end of the fuze-body A, a nose G screwed on the projecting end of the block 1 being provided with vanes 5 whereby the nose is unscrewed in flight from the safety position shown in Fig. 1 to the operative position shown in Fig. 3. Inertia spring-loaded pins 8 and HI normally hold the nose G at safe. The inner end of the plunger 7 is arranged to operate the firing-pin 35 by pressure upon a delay pellet 15 without firing the pellet. The magazine charge 50 is normally sealed from the detonator D by a shutter C as shown in Fig. 2. Under centrifugal action, assisted by springs 42, the shutter is moved from the safety position shown, to bring an aperture 47 into axial alignment with the primer 31 and diaphragms 30, 30a normally blocking the flash passage. The shutter is locked in the open position by the engagement of a pair of spring-pressed detents 45 over the shoulders B 1  of a plate B in which the shutter is guided. To provide interaction between the graze detonator 17 and the impact detonator D, the plug E has a flash passage 16 communicating through ports 7a, 7b in the plunger 7 with the delay pellet 15. Pockets 27 in the plug 36 carrying the impact firing pin 35 are packed with powder, the ignition of which by the pellet 15 drives the pin 35 on to the detonator D. The plug E is normally locked by a centrifugal bolt 25 which is itself held, before firing, by an inertia-operated non- return detent H 2 . A similar detent H 3  is fitted to hold the shutter C at safety. The plunger 7 may be removed and replaced by a short screw-plug, in which case the graze mechanism functions as a delay-action percussion device both under direct impact and on graze impact.

Abstract: 726,597. Bomb shelters. HALL, A. G. W. May 7, 1952 [May 11, 1951], No. 11211/51. Class 20 (1). A bomb shelter comprises a number of flat tapering strips 10 of sheet material arranged side by side with their edges overlapping or abutting one another with adjacent strips secured together at these edges by bolts 11 or plates 12 &c. and each strip secured at its apex to a common centre plate 14 so as to provide a substantially dome-shaped structure, and a covering 15 of concrete, earth or other solid material over the domw-shaped enclosure. The centre plate may be supported on a pole. The strips 10 which are similarly shaped, e.g. triangular, trapezoidal, or sectors of a sphere, may be formed of metal, bonded glass fibres, stiffened paper, or fibrous material impregnated with a waterproof compound, and may be covered with a waterproof material before the concrete is applied. The concrete, which may be reinforced, may diminish in thickness towards the crown. According to one method of erection the strips are connected together and to the centre plate to form a dome, tapering side strips of non- metallic material, e.g. vulcanized fibre are secured to two adjacent rows of bolts, a retaining layer, e.g. of bitumen coated paper with or without wire reinforcement or wire mesh, secured across adjacent strips, concrete cast into this mould, and the process repeated between each two adjacent rows of bolts. Fig. 4 shows a method of constructing the shelter in which the concrete 15 is retained by a layer of stiff material 24 with or without wire reinforcement and strips 22 secured to the bolts 11. When the strips 10 are connected without upstanding bolts, e.g. as in Fig. 5, an inner and outer domed shell may be erected and the space between filled with concrete &c., drain holes being provided at the base of the space. The strips 10 may be patterned for strengthening. The shelter may be erected over a concrete-lined hole in the ground, and a stepped entrance with covering boards constructed. Flanged sections 21 secured to the strips 10 may be used to form the opening to the shelter.

IPC: B65D39/04
Filed: 1963-03-21
Abstract: 1,018,514. Closuring containers. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. March 21, 1963, No. 11337/63. Headings B8C, B8D and B8T. [Also in Division B5] A method of'closing an opening 3 in a plastics container comprises the steps of covering the opening with a plastics lid 4, exerting pressure on the lid and causing rotation of the lid relative to the container so that the heat of friction developed at the surfaces of contact 5 and 6 on the lid and container respectively causes some melting of the material of these surfaces, stopping the rotation, and maintaining the pressure on the lid until the molten material has set. In the embodiment the container is held fixed and rotation of the lid is effected by bringing extensions 12 on a disc 11 attached to a rotating spindle 10, into engagement with lugs 9 formed in a recess 7 in the lid, pressure being applied by an annular elastic element 13 on the disc 11. To ease control of relative rotation and prevent any plastics chippings from entering the container, a thin film of oil is placed between the surfaces 5 and 6 before performing the closing operation.

Title: Improvements in grinding machines
IPC: B24B41/06
Filed: 1923-04-28
Abstract: 213,783. Dudgeon, H. A. April 28, 1923. Rollers, spindles, tubes, and the like, treating.-In a machine for grinding the periphery of pins, rollers, tubes, &c. wherein the work 6, Fig. 2, is fed in a guide channel across the face of a single grinding disc 10 and the rate of axial feed of the work is varied by adjustment of the guide channel parallel to the face of the disc as described in Specification 139,366, means are provided for effecting a limited relative movement of the workrest 2 relatively to the disc to allow of the introduction of work having an enlargement at one or both ends. The guide-channel is formed by plates 3, 4, 5 carried by the work-rest 2, which is pivoted to a carrier 8 capable of tilting about a shaft 9 to vary the direction of feed of the work. An eccentric shaft 11 journaled in a bracket secured to the work-rest 2 engages a channel 12 formed in the carrier 8. Rotation of this shaft against the action of a spring withdraws the workrest a limited distance from the disc 10. The plate 3 is omitted when work having an enlargement at both ends is operated upon. The tilting movement of the carrier is limited by adjustable stops, and in a modification, shown in Fig. 5, a cam handle 26 replaces the eccentric shaft. In the construction shown in Fig. 10, the eccentric shaft 11 is retained but the work-rest 2 slides upon a stud 42 adjustably mounted on the carrier 8. Alternatively a sleeve, nut 44, Fig. 12, may be placed around the usual feed screw 45, and by locking the hand-wheel 47 a limited movement of the work-rest is obtained upon movement of a handle 48 secured to the sleeve nut. A circular rack 30, Fig. 8, ma.y be formed in the shaft 9 or in a sleeve surrounding the shaft, so that the limited withdrawal of the work-rest 2 is effected by rotation of a pinion 29 meshing with the rack, a spring 31 effecting the return movement of the work-rest. In the construction shown in Fig. 13, the rate and direction of feed is varied by moving the work-rest approximately parallel to the disc 10 by means of a screw 54, and the limited movement is obtained by a rack and pinion 57, 58. The rack and pinion may be omitted, the limited movement necessary for insertion of the work being obtained by having the screw 54 inclined away from the disc 10. In a further modification the limited relative movement is obtained by moving the grinding-disc away from the workrest. Annular packing-rings 50 exclude water from the bearing of the shaft 9.

Title: Improvements in or relating to acrylonitrile copolymers and articles made therefrom
IPC: C08J3/09
Filed: 1951-05-17
Abstract: A homogeneous solution suitable for the production of films, fibres, adhesives, coatings and the like comprises a copolymer of acrylonitrile and vinyl chloride, containing between 30 per cent. and 75 per cent. of acrylonitrile, dissolved in acetonitrile. Dissolution is effected at elevated temperatures, e.g. up to 125 DEG C., the copolymer being insoluble at temperatures below about 50 DEG C. Stabilisers, such as organo tin and lead salts, e.g. dibutyl tin maleate and dibutyl tin di (ethylpropylacrylate), may be added. Filaments and yarns may be wet- or dry-spun at temperatures between 60 DEG  and 80 DEG C.  Excess solvent is removed from the filaments by hot air or by immersion in a non-solvent for the resin which is a solvent for acetonitrile, e.g. water, which itself may contain up to 30 per cent. acetonitrile.  This mixture is the preferred coagulant for wet-spinning.  The yarns may be stretched from 100 per cent. to 1500 per cent. at temperatures between 140 DEG  and 150 DEG C. and then heated to 150 DEG -225 DEG C. for short periods.  The desired copolymers, which have a specific viscosity of 0.15 to 0.7, are preferably prepared in aqueous emulsion in the presence of usual emulsifying agents and catalysts and, if desired, mercaptans to control the molecular weight.  A constant ratio of monomers is preferably maintained by addition of acrylonitrile during polymerisation.  For copolymers having acrylonitrile contents of 60-71 per cent., the weight ratio of acrylonitrile to vinyl chloride is within the range 1 to 3.7 to 1 to 1.7; for copolymers having 75 per cent. acrylonitrile, the ratio is 1 to 1.3.  The mercaptan may also be added during the polymerisation.
