Title: Process for Pressure-Forging Thickenings on Pipe Ends
Inventor: HERTEL HEINRICH
IPC: B21J5/08
Filed: 1967-04-24
Abstract: 1,177,017. Upsetting pipe ends; stamping. H. HERTEL. 24 April, 1967 [14 May, 1966], No. 18821/67. Headings B3H and B3Q. The end of a pipe 2 is hot or cold upset by clamping the pipe at 3, enclosing the projecting pipe end in a die 1 and whilst the bore of the pipe is unrestricted, upsetting the end by a punch 4 inserted into the die. The pipe wall is thus thickened internally, Fig. 2 (not shown). Percussive impact forces, such as by explosive pressure, are applied to the hollow punch 4. The pipe may be disposed vertically or horizontally during upsetting. After upsetting the original internal diameter of the pipe may be restored by expanding it in a die by hydraulic or explosive pressure or by an internal plug. During this operation external threads may be formed.

Title: Improvements relating to electric gas-discharge rectifiers with thermionic cathodes
IPC: H02H7/12
Filed: 1930-06-23
Abstract: 353,203. Rectifying alternating currents ; valve circuits. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, CLARK, F. and FROGLEY, W. G., both of General Electric Co., Stoke, Coventry, and WATSON, D. I., of General Electric Co., Wembley, Middlesex. June 23, 1930, No. 19099. [Class 38 (ii).] In order to prevent damage to a gas-discharge thermionic rectifier by full load being applied at the moment of switching on of the rectifier, a delay is introduced by means of an indirectly heated cathode valve. A gas discharge rectifier consisting of one or more mercury rectifiers C with thermionic cathodes supplies power to a valve D. Grid bias is applied to D in a known manner by inserting a resistance A between the filament-heating circuit and earth. In series with resistance A is another resistance B of such a value that the grid bias applied by A, B in series is so great that the valve D can only take a fraction of its full load. Resistance B can be short-circuited by a relay E included in the circuit of an indirectly heated cathode valve F. When the circuit is switched on, the valve D cannot draw its full power until the valve F has developed appreciable thermionic emission and thereby has operated the relay E. In a modification the relay E short-circuits a resistance in the anode feed lead of the triode D. Specification 246,897, [Class 38 (ii), Electric currents, Converting &c.], is referred to.

A shear for severing strip, bar-stock, anglesections &c. 49 between apertured cutters 40, 41 comprises means for delivering opposite impacts to the cutters. A bush 42 in a multi-piece block 43 extending between front and back plates 10, 11 of the shear guides the cutters, which are fixed by screws 45 to rams 36, 37. These are guided in bushes 38 and operated by roller-cams 30 on oppositely rotating drums 13, 14. A gag 35 transmitting the impact between each drum and one of the rams is pressed by a pneumatic piston 93 against the ram and may be retracted clear of the cam 30 by exhausting the air beneath a diaphrag-piston 91 supporting the gag. Return movements of the rams are by bellcrank lev rs 61, one arm 64 of which engages a ram and the other, 66, a spring-loaded dash-pot plunger 67. Adjustable stops 70 in blocks 39 supporting the guides 38 limit return movements of the rams.

Title: Improvements in and relating to polysiloxane resins
Filed: 1945-08-03
Abstract: A metal naphthenate is incorporated as curing agent into a composition containing an organo-polysiloxane containing between 1 and 2 hydrocarbon radicals per silicon atom, the metal present being not more than 1 per cent by weight of the organo-polysiloxane. Suitable polysiloxanes are described in Specifications 542,655 and 548,911.  The metal salt is preferably added just before the composition is used.  It lowers the time and temperature of curing. Naphthenates mentioned are those of lead, tin, magnesium, cobalt, iron, sodium, potassium, vanadium, cadmium, copper, barium, strontium, cerium, thorium, chromium, manganese, zinc, aluminium, nickel, mercury and calcium.  Tests were made on a solution in toluene and butanol of a resin prepared by hydrolysis and condensation of a mixture of 90 per cent methyl trichlorosilane and 10 per cent dimethyl dichlorosilane, by measuring the time of gelation of the samples of the solution heated in a water bath in presence of various metal naphthenates. The lower curing temperatures make the composition useful as coatings or impregnants for paper, cotton or linen.  Methyl phenyl polysiloxane resins are particularly fast curing in the presence of the naphthenates, a film containing .02 per cent lead as naphthenate becoming quite dry in 10-20 minutes at 170 DEG  C. or 30-60 minutes at 150 DEG  C. on a base of paper, metal or cloth. Combined with paper, cotton or glass cloth the resins with added naphthenates may be used as condenser dielectrics or as wire or cable insulation.  Compositions may be used for enamels, e.g. for wire, or as varnishes for coils.  Titanium dioxide is mentioned as an enamel pigment.  The Specification as open to inspection under Sect. 91 includes the use of metal salts other than the naphthenate, provided they are soluble in the compositions and mentions as suitable acid radicals, resinate, linoleate, stearate, oleate, acetate, butyrate.  This subject-matter does not appear in the Specification as accepted.
