Title: Method and apparatus for plating metal
IPC: B23K20/08
Filed: 1965-06-16
Abstract: 1,105,152. Welding by pressure. BROWN, BOVERI & CIE A.G. 16 June, 1965 [30 June, 1964], No. 25512/65. Heading B3R. In a method of plating a metal foil 2 on to a metal support 1 the required pressure wave for the operation is generated by one or more pressure generators which act upon the metal foil 2 after actuation by electric impulses. The pressure generators may be magnetic field coils 3 or may be spark gaps or evaporable wires which transmit a shock wave through a medium having a density higher than air such as water, sand or the like. The magnetic field coils 3 may be operated in a desired chronological order by having delay cables 9 controlling the time when an ignition impulse fed to connections 10 reaches an ignition pin 8 arranged in a spark gap 5. Condensers 4 are charged through connections 6 and discharge into the magnetic field coils 3 across the spark gap 5 when the ignition pin 8 receives its impulse. The pressure wave may also be obtained by supplying successive ignition pulses or by arranging the foil 2 at a slight angle to the support 1. Several layers of metal may be plated one upon the other successively or simultaneously and partial plating may be carried out by the method.

Patent GB-869829-A (GB)
Title: Preparation of vinyl esters
Filed: 1957-08-21
Abstract: Vinyl esters are prepared by a vinyl interchange reaction which comprises reacting with heat a carboxylic acid together with a vinyl ester reactant in the presence of a vinyl interchange catalyst to form a reaction product containing the corresponding vinyl ester of the carboxylic acid and the by-product acid of the vinyl ester reactant, removing the by-product acid from the reaction medium and continuing the vinyl interchange reaction until substantially complete.  The by-product acid can be removed by entrainment in the vapour of the vinyl ester reactant, for example by passing the said vapour through the reaction mixture or by rapidly distilling the said vapour from the reaction mixture while adding fresh vinyl ester to maintain the correct proportions.  The reaction medium may be passed downwardly through a heated bubble plate reaction column and the vinyl ester vapour passed upwardly through the column.  The by-product acid is then separated from the vinyl ester vapour, e.g. by distillation, and the ester is recycled to the column.  The reaction product is neutralized and stripped of vinyl ester reactant, and purified by distillation.  The product may be further purified by dissolving in a hydrocarbon solvent such as pentane, hexane or heptane and liming the solution.  The vinyl ester may be further purified by contacting with one or more absorbents comprising magnesium oxide, magnesium silicate and activated carbon.  Mercury salt-strong acid catalysts are most effective in the process, using, e.g. mercuric oxide, acetate or stearate with sulphuric, phosphoric, p-toluene sulphonic or trifluoroacetic acid.  Examples describe the preparation of divinyl sebacate, vinyl benzoate, methyl vinyl phthalate, vinyl cyclohexane carboxylate, divinyl adipate, vinyl toluate, vinyl stearatepalmitate, methyl vinyl succinate, vinyl pelargonate, and vinyl oleate.  Specification 869,828 is referred to.
