In an hydraulic electric resistance welding-head comprising a cylinder 10, a piston 18 slidable in the cylinder between retracted and extended positions, a first port 14 in the cylinder to conduct pressure to one face of the piston, a second port 15 to conduct pressure to the opposite face, a piston insert 17 fixed within the piston, means 29 to conduct fluid from the first post to a piston face 19 on the piston insert, and an electrode carrier 13, there is provided a compression - spring 47 between the outer end of the piston and the carrier, the spring being compressed when the piston is in its extended position and the work engaged and being able to expand and maintain a pressure on the work when the latter yields at elevated temperature. The piston 18 having an upper annular part with opposite faces 27, 43 and a lower skirt slides with a key 26 and slot 25 connection in a bore 23 of the cylinder about a piston retainer 28 fixed in the cylinder. The insert 17 is secured in the lower end of the skirt and the carrier 13 for an electrode 61 is slidable therein and is secured thereto by a pin 58 and slot 57 connection. The spring 47 in the form of stacked cone-shaped discs is arranged about a pin 49 on the carrier and acts on the head 52 of the pin and a washer 53 engaging the top of the insert. In operation hydraulic fluid is supplied to the port 14 to act on the surface 27 of the piston 18, and, via a bore 29 in the retainer, on the upper face of the insert 17 to lower the piston 18 and the electrode 61, the electrode engaging the work and the spring being compressed until the upper end of the carrier 13 engages the washer 53. After welding current is supplied the work parts yield and the spring expands so that the electrode follows up. To return the piston and electrode hydraulic fluid is supplied to the port 15 or a port 38 and through bores 45, 46 in the retainer to the underface 43 of the piston 18.

Abstract: 250,927. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. April 17, 1925, [Convention date]. Addition to 194,637. R÷ntgen-ray tubes. -- An anticathode having a hollow chromeiron portion sealed to a glass wall, as described in the parent Specifition, is provided in the chromeiron portion with metal or alloy of high heat conductivity bearing a tungsten or other block, forming the target. The metal, preferably electrolytic red copper, is placed in the chrome-iron vessel 1 having a block 8 of chrome-iron with a sloping surface carrying a target 3, and is heated so as to form, on cooling, a block 4 in contact with the target. Heating may be effected in a vacuum by high frequency induced current; or air may be excluded by adding substances forming a slag on the surface of copper, the heating being by a gas burner. The copper block 4 is subsequently tapped to receive a cooling tube 7 or rod, and the chrome-iron block and vessel are shaped, as by grinding or turning, so as to leave an opening indicated by dotted lines 9, and expose the target. In another arrangement the chrome-iron block is omitted, and the target is arranged in the base of the chrome-iron vessel.

Patent GB-703399-A (GB)
Title: Preparation of unsaturated nitriles
Inventor: ARMSTRONG GODFREY PAUL
Filed: 1950-04-15
Abstract: Alpha-beta unsaturated nitriles are produced by the pyrolysis of an alkoxy nitrile of formula <FORM:0703399/IV(b)/1> in which R1, R2, R3 may be hydrogen, unsubstituted alkyl, cycloalkyl, aralkyl and aryl radicals and R4 is an unsubstituted alkyl group.  R1, R2 and R3 may be, for example, methyl, ethyl, propyl, butyl, cyclohexyl, benzyl, phenyl, tolyl or xylyl radicals and R4 may be, for example, methyl, ethyl, propyl or butyl radicals.  The starting material is heated to a temperature between 250 DEG  and 500 DEG  C. and the reaction is preferably carried out in the vapour phase. The alpha-beta unsaturated nitrile is isolated from the reaction mixture preferably by distillation.  Preferably the starting material is R5O-CH2-(R6)CH-CN where R5 is an alkyl group and R6 is hydrogen or an alkyl group.  The pyrolysis is preferably carried out in the presence of a pyrolysing catalyst, e.g. alumina, silica gel, active earths, acid-activated earths, mixed alumina-silica gel catalysts, strong acids such as sulphuric acid and phosphoric acid, esters of strong acids such as isopropyl sulphate, ion, zinc or calcium oxide, or catalyst supports containing mineral acids, such as phosphoric acid, or salts thereof, or metal oxides.  The pyrolysis may also be carried out in the presence of an inert diluent such as nitrogen or carbon dioxide.  The reaction is preferably carried out in the presence of a small amount of a volatile acid and/or a small amount of an acid, for example, a mineral acid is added to the reaction products before they are isolated.  The most suitable acid for this purpose is a fatty acid such as acetic acid.  The process is of particular application in the production of acrylonitrile by the pyrolysis of 3-methoxy-propionitrile and of 2-methacrylonitrile by the pyrolysis of 3-methoxyisobutyronitrile.  It is also applicable to the production of atroponitrile by the pyrolysis of alphaphenyl-betamethoxy propionitrile or of cinnamonitrile by the pyrolysis of betaphenylbetamethoxy propionitrile.  In the examples 3-methoxypropronitrile is converted to acrylonitrile in the presence of various catalysts.  Specification 703,398 is referred to.
