Patent GB-1302055-A (GB)
IPC: B23K35/02
Filed: 1970-09-16
Abstract: 1302055 Welding by fusion OSAKA TRANSFORMER CO Ltd 16 Sept 1970 [16 Sept 1969] 44252/70 Heading B3R [Also in Division F2] Wire 12 (e.g. consumable electrode wire in arc welding), drawn from a supply reel and fed through a tube 11 (e.g. to a welding torch) by a roller feed mechanism 4, 8, is lubricated to reduce wire/tube friction resistance by a solid lubricant block 33 pressed transversely on to the wire. The lubricant block is preferably of graphite, MoS 2  or a bound mixture thereof, e.g. 19% powdery MoS 2  and 79% powdery graphite with 2% binder of epoxy resin. In Fig. 2, the roller feed mechanism comprises a motordriven roller 4 and a spring-pressed idler roller 8 pivoted on a structure 13. The latter has wire guide inserts 25, 27, the insert 27 being supported by a cylindrical member 14 (formed as an extension of the structure 13) and being threaded at 29 to receive the tube 11. The lubricant block is housed in aligned cavities 30, 31 in the cylindrical member 14 and insert 27, and pressed against the wire by a weight 34 which may be changed to adjust block/wire pressure. Preferably a wire accommodating groove (35) is pre-formed in the lubricant block. In Fig. 5, pressure on the block is effected by a spring 38 reacting on a threaded pressure-adjusting plug 37. A rod 40 fast in the lubricant block and extending through the plug forms a handle for temporarily raising the block clear of the wire. A plurality of lubricant blocks may be provided on the cylindrical member 14, circumferentially spaced, or diametrically opposite and axially spaced (Figs. 5-7, not shown). In Fig. 8 (not shown), two diametrically opposite lubricant blocks are housed in a cylindrical member which is made separate from the structure 13 and threaded on to the insert 27. In Figs. 9, 10 (not shown), the plug 37 has, respectively, a solid or hollow extension (41, 42) within or surrounding a spring 38 and engageable with the lubricant block, optimum spring pressure being thereby set by screwing down the plug until said extension engages the block and then unscrewing the plug one half turn. The spring is such as to provide a substantially constant pressure as the lubricant wears away. In Fig. 11, tension springs 52 act on the block via a cross-member 44b engaged in grooves 45 of an extension 36 of the cylindrical member 14. The tension springs are loaded by a screw plug 47 acting on a spring anchor cap 48. Spring loading is limited by engagement of the cap with arms 44c extending from the cross member 44b. Means holding the lubricant block clear or out of the path of the wire may comprise a transverse pin fast in the block and engageable in a bayonet slot in the cylindrical member 14 (Figs. 12, 13, not shown), a peg engageable in a transverse hole of the block-fast rod of Fig. 5 in the raised position of the rod (Fig. 15, not shown), or a plunger arranged to press upwardly on the block, said plunger being screw set (Fig. 14, not shown) or transverse auxiliary plunger detained (Fig. 16, not shown).

Abstract: 1,106,218. Stopping leaks in pipes; connecting branches. NORTH THAMES GAS BOARD. 18 Oct., 1966 [19 Oct., 1965], No. 44258/65. Headings F2'G and F2P. A leak in a pipe line is contained by securing a mounting around the pipe 5 and, by forcing a carrier 13 along a guide 11 rigidly attached to the mounting, moving a resilient tubular sealing element 15 sealed at one end to the carrier, which has a venting passage 17 communicating with the interior of the sealing member, into engagement with the pipe 5 to form an annular seal around the leak. The sealing element 15 is sealed to the carrier by entering a groove 16 provided in the latter, and the carrier is moved towards the pipe by the screws 18. A tube 14 which extends the venting passage has a screwthreaded end 19 to receive a shut-off valve. The mounting may be welded to the pipe.

Title: Improvements relating to safety devices for automobile and aeroplane travellers
IPC: B64D25/06
Filed: 1963-11-12
Abstract: 1,069,646. Safety harness. VEREINIGTE GLANZSTOFF-FABRIKEN A.G. Nov. 12, 1963 [Nov. 16, 1962], No. 44657/63. Heading A3V. [Also in Division F2] A safety braking device for vehicle occupants and parachutists is connected to a belt or harness and, in the event of sudden decelaration of the vehicle or parachute, progressively absorbs kinetic energy acting on the body of the user without being permanently deformed or destroyed itself, and after the energy absorption it either remains in the position it has reached or gradually returns to its initial position. As shown, Fig. 2, a piston rod 7 to which is connected a safety belt (not shown) is housed in an inner cylinder 4 communicating with an outer cylinder 1 through openings 8 and 9, both cylinders being filled with brake fluid. When, e.g. on sudden braking of the vehicle, a tractive force is exerted on the piston rod 7 the piston 6 forces fluid through the openings 8 into the cylinder 1 whence it returns to the inner cylinder through openings 9. Due to the progressive closing of the openings 8 and the increased friction of the fluid, an increasing braking action on the piston movement takes place. A spring 5 returns the piston slowly to its initial positon. In an alternative construction, Fig. 3, not shown, the piston rod (7) when subjected to tractive force compresses a spring (5) against abutments on clips (11) which are pivoted on the cylinder (13), for limited outward movement. At maximum compression of the spring the piston forces the abutments apart sufficiently to allow the spring to expand into the upper part of the cylinder, stops (14) preventing greater opening of the clips (11). This embodiment is rendered operational again by clamping the spring (5) between the piston (6) and the clips (11).

The wedges and plates are preferably made of quartz and the plates have a number of grooves, see Fig. 1.1, to ensure that the bending and flexing under the action of the force takes place at the grooves leaving the part of the plate with the wedges to move in the direction of the y axis without twisting &c. (see Fig. 1.1) The description and Figures deal with two ways of forming the interference fringes; the first (Fig. 3) involves radiation from a source 1 being directed through the wedges &c. as shown to be received by a number of photo-sensors 5, and the other way Fig. 4 (not shown) involves radiation that has been reflected off the wedges.
