Title: Method of and apparatus for joining two elements of metal or thermoplastics material by friction welding
IPC: B29C65/06
Filed: 1971-06-04
Abstract: 1322815 Seaming NAPHTACHIMIE 4 June 1971 [5 June 1970] 19044/71 Heading B5K [Also in Division B3] In joining two elements 2, 3 of metal or thermoplastics material member, the elements are placed with their surfaces to be joined facing one another in parallel planes, an intermediate member is placed between the surfaces and is rotated or oscillated about an axis perpendicular to the surfaces while exerting a force on at least one of the elements to move the elements relatively together and bring the surfaces into contact with surfaces of the intermediate member and the position of the intermediate member is controlled by an apparatus responsive to differences in temperature and/or softening of material of the two pairs of contacting surfaces and including a double acting ram for adjusting the position of the intermediate member, the material of the contacting surfaces being joined in friction welds. Elements, e.g. pipes, of polyethylene or polyvinyl chloride may be joined. To join a further pipe 3 on to a pipe 2 forming part of a pipe system the pipes 2 and 3 and an intermediate shorter pipe length 4 are supported by a self propelled carriage 1, incorporating an endless track 7, connected by a link 6 to a further carriage supporting the pipe 3. A clamping assembly is pivoted to the carriage 1 at 8 and comprises clamps 9, 10 for the pipes 2, 3 capable of being drawn together by a ram 11, and jaws 13 for the length 4, carrying a drive ring 14 rotatable by a motor. A double-acting ram 20 connected between the clamp 9 and the ring 14 positions the length 4. In use with the pipes 2, 3 clamped, the length 4 is rotated or oscillated and the pipes 2, 3 are then brought together until the rubbing surfaces soften, the position of the length 4 being continuously adjusted by the ram 20 to obtain identical conditions at both ends, the rotation or oscillation is stopped and the ram 11 continues to apply a force until the welds harden. A control apparatus receiving information from gauges measuring flow of metal at the weld zones and optical pyrometers measuring temperature at the weld zones, controls the operation of the ram 20. The intermediate member may be a circular collar or two collars bolted together. Two pipes at an angle to one another or two pipes of different diameters may be joined and a pipe may be joined to a flange, a valve or T-shaped conduit employing a suitable intermediate.

Title: Method of making mobile tanks for liqudis and the tanks obtained by this method
IPC: B65D90/52
Filed: 1972-04-25
Abstract: 1379617 Vehicle and aircraft fuel tanks CEGEDUR GP 25 April 1972 [26 April 1971] 19138/72 Headings B7H and B7W [Also in Division B8] A tank (e.g. a fuel tank for road or rail vehicles, ships or small aircraft, or a mobile tank for water, liquid food, chemical products or universal application) includes an outer metal wall and at least one anti-surge baffle consisting of an expanded foam core covered with a lining of plastics material, the lining also covering at least part of the outer metal wall. The baffle is made by pre-forming the plastics lining, e.g. by vacuum moulding, assembling the formed lining with the metal outer wall and injecting components which react to form an expanded foam into the space between the lining and outer wall In a first embodiment (Fig. 5) the plastics lining 4 completely covers the inner surface of the tank and consists of two halves 41, 42 which are pre-moulded and which are joined by a liquid-tight weld along flanges 411, 421. The lining 4 is then assembled with two metal tank halves 31, 32 which are joined by crimping at 3211 or by spot welding (not shown). The reaction mixture for the expanded foam is then injected through openings 3181, 3182 and 3281. The expanded foam forms a main baffle 412, 422, an optional baffle 423 and triangular edge members 414, 424 which help bond the lining 4 to the outer wall 3. This bonding may be improved by providing undercut parts, e.g. of dovetail shape (not shown) in either the outer wall 3 or lining 4. The tank is also provided with a filler tube 512, an opening 4161 for a fuel gauge mechanism and an outlet 521. In a second embodiment (Fig. 8) only the top half 61 of the outer metal wall 61, 62 is lined, a transverse baffle 72 having a foam core being formed on the upper wall 61. In a third embodiment (Fig. 10) a generally unlined tank is provided with a baffle by holding a plastics moulding 9 against the metal wall 81 and injecting a foam forming reaction mixture into the spaces 93, 94, 95 to form the foam core and to bond the baffle to the outer wall. The plastics lining and foam material may also form additional members. For example, as shown in Fig. 12, the upper lining 21 may have a projection 2100 fixed to a filler tube 117, the foam core 2121 filling the space between the lining 2100 and tube 117 and bonding them together. The lower lining 22 may be formed with a projection 2200 filled with a foamed core 2221 which co-operates with the filler tube 117 to provide a throttling effect on the liquid input and an anti-drip device.

Title: Improvements in or relating to switches for use in electric lighting systems
IPC: H01H51/08
Filed: 1919-08-05
Abstract: 145,293. Wescott, D. E. Aug. 5, 1919. Lighting systems.-A switch in an arc lamp or constant current circuit is used to control the supply through a transformer to a number of auxiliary incandescent lamp circuits which can be extinguished separately. The switch 8 is in the main arc-lamp circuit, which also contains two electro-magnets 9. 14 for the primary and secondary of the transformer. The secondary is divided, the separate lamp circuits being connected to the parts. With both switches 9, 14 closed all the circuits are under supply; with the switch 9 only closed, only a part of the auxiliary lamp circuits are energized. To enable the switch 9 to be closed, when the switch 14 is open, the latter has a rod 25 suspended from the movable contact member 16; this rod carries a cross-pin 27 which enters either deep or shallow notches in a ring 31. When in the shallow notch the switch cannot close, although the electro-magnet is energized by closing the switch 8. To move the cross-pin round from a deep to a shallow notch and vice versa the switch 8 is opened momentarily. The pin in dropping falls on inclined teeth 42 in a second ring 30 and moves round; when the switch 8 is closed again the contact in rising brings the cross-pin into the next notch and so holds the switch open or allows it to close according as to whether it was previously closed or open. When the switch 8 is left open all the lamps are extinguished. Specification 145,200 is referred to.
