Title: Method of and apparatus for use in welding pipe joints
IPC: B23K9/16
Filed: 1962-03-16
Abstract: 952,952. Welding by fusion. BRITISH PETROLEUM CO. Ltd., and R. M. BROWN. Feb. 7, 1963 [March 16, 1962], No. 10149/62. Heading B3R. Prior to welding pipes end-to-end, an interior portion of the pipes around the joint is isolated by inflating one or more inflatable members and the portion is filled with a substance, e.g., an inert gas or a flux, for aiding the welding. An inflatable member 10 is formed by forming weld seams along the lines shown in full in Fig. 1, in a pair of superimposed layers of plastic or metal, e.g. aluminium, foil, to form a pocket 15 extending along both sides and an end of the member 10. This end is narrower and fits within the other end when inflated as shown in Fig. 2. The inflatable member 10 is located in a pipe 25 by adhesive strip 32 and a fusible insert of the same metal as the pipes 24, 25 is positioned at the root of the seam. Inflation is effected through a tube connected to the pocket 15 or by a substance in the pocket 15 during preheating of the pipes. Inert gas, e.g., argon, is fed through a tube 31 in the insert to the space enclosed by the member 10 and the seam is welded by a gas shielded arc welding torch 27. Subsequently the joint is stress-relieved at a temperature that causes the member 10 to collapse or melt and the member 10 is washed away during hydrostatic testing of the weld.

Title: Improved means for signalling the passage or otherwise of coal or other material through a chute or the like
IPC: G01P13/00
Filed: 1954-04-08
Abstract: 812,545. Electric tests. CLARKE, CHAPMAN & CO. Ltd., and WOODESON, J. B. April 12, 1955 [April 8, 1954; May 31, 1954], Nos. 10390/54 and 16071/54. Class 37. [Also in Group XXX] Apparatus for signalling the passage or otherwise of coal or similar conductive material in a shoot exhibits different signals which distinguish an empty shoot, a jammed or blocked shoot and a shoot in which material is flowing normally. The invention is dependent on the conductive material producing a varying resistance across electrodes during normal flow and a constant resistance when jamming occurs. When coal is moving down shoot 2 the varying resistance through the coal then prevailing between insulated electrode 3 and the metal sides of shoot 2 produces a varying current in the primary 10 of transformer T1. The output of T1 is amplified by double triode V2 and via transformer T2 and rectifier 32 maintains pentode V3 conducting and relay A operated so that through closed contacts 55/57 so that signal lamp 62 is illuminated to indicate normal flow. If the shoot should become jammed with coal a constant resistance through the coal prevails between electrode 3 and the metal sides of shoot 2 so that no varying current flows in the primary 10 of transformer T1 and the output of T1 is zero and V3 is therefore biased to cut-off whereby relay A releases to operate alarm 64 and signal lamp 62 via relay A closed contacts 55-57 and relay B closed contacts 51/53 to indicate the jammed condition. If the shoot should become empty a very high resistance prevails between electrode 3 and the metal sides of shoot 2 so that via the primary 10 of T1 and resistor 13 the grid of pentode V1 goes more positive whereby V1 conducts and operates relay B. Also the output of T1 is again zero so that V3 is rendered non-conductive and relay A releases to sound alarm 62 and light signal lamp 63 via relay A closed contacts 55/57 and relay B closed contacts 52/54 to indicate the empty condition.

Title: Improvements in or relating to power transmission clutches and gears
IPC: F16D23/08
Filed: 1930-04-02
Abstract: 356,140. Variable speed gearing. CARLING, W. T., Tangley, Sydney Road, Guildford, Surrey. April 2, 1930, No. 10407. [Classes 80 (i) and 80 (ii).] In a clocking device, particularly to facilitate changing down in variable-speed gearing by preventing inopportune engagement of power transmitting members such as positive clutch elements or sliding toothed wheels, wherein the preventative locking takes place in two stages as described in Specifications 327,191, [Class 80 (ii), Gearing, Variablespeed &c.], and 341,906, means are provided such as an intermittent drag or friction ring operating on the locking ring during axial movement of the engaging member for preventing a state of unlock between successive stages due to rebound and/or the viscosity or turbulence of the gear box. lubricant. A toothed wheel 2 is positively clutched to a driven shaft 7 by an axially slidable clutch element 5, engaging movement of which is prevented until the speeds are synchronized by a locking element 1 freely mounted on wheel 2 and having fingers 1d passing through arcuate slots in member 5 and having staggered locking shoulders 1b, 1c. A slidable ring 3 rotatable with wheel 2 is freely mounted in a channel formed between a flange on, and quadrants 3b screwed to, the locking member 1. Disc 3 is axially moved during engagement by the engaging fork 6E acting through a spring 15 which overcomes a weaker return spring 11. Domes 1a in the locking ring are thereby intermittently engaged with recesses 2c in the wheel 2, so that on changing down with shaft 7 rotating faster than wheel 2 engagement is prevented by locking shoulder 1b. The wheel 2 is then speeded up by accelerating the engine, and consequent on a reversal of speed relation member 5 is allowed to move further and is then locked by shoulder 1c. A further reversal of speed relation consequent on slowing the engine allows the member 5 to engage fully whereon a projection 6G on its operating fork engages an extension 10b of the lever 10 moves it back against a stop 14 to relieve the ring 3 of its axial pressure. In a modification the ring 3 is not carried in a channel in the locking ring but is directly pressed against it by pivoted arms connected to a further resilient arm under the end of which passes an enlargement on the operating shaft 6, first applying a resilient pressure to the ring and afterwards allowing the arms to be spring-returned to the free position. The locking ring 1 is then disengaged by spring-pressed plungers between it and the wheel 2. Frictional engagement may replace the intermittent dome and recess arrangement described. The method of preventing inopportune meshing of sliding toothed wheels is as described in Specification 307,631, [Class 80 (ii), Gearing, Variable speed &c.]. Specification 294,301, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to in the Provisional Specification with regard to the modification described above.
