Patent GB-2145736-A (GB)
Title: Electro-chemical removal of metallic material
Inventor: THILOW ALFRED
IPC: B23H3/00
Filed: 1983-08-25
Abstract: Metallic material is removed from a workpiece 10, e.g. the combustion chamber of the cylinder head of an internal combustion engine, by means of a tool electrode 11 which is at an electrical operating voltage with respect to the workpiece 10 wherein the gap 12 between the tool electrode 11 and the workpiece 10 is filled by a liquid electrolyte, e.g. NaNO3, and a correction of the volume 12 filled by the electrolyte is carried out by the electro-chemical removal of metallic material from the workpiece 10 proceeding from different initial volumes to a predetermined greater final volume wherein the amount of the particular removal required is determined by a previously calculated final value of an electrical parameter prevailing during the machining. The volume of each combustion chamber in a cylinder head after casting may be slightly different and the invention allows the combustion chambers to be machined to exactly the same volume. In one embodiment, the electrode and workpiece are stationary, the voltage is constant and removal is continued until a predetermined current value (as a measure of the electrochemical removal) is attained. Alternatively, the resistance between the electrode and workpiece may be determined as a measure of the amount of removal required, the product or integral of the current and time required is then calculated on the basis of the resistance value, and the removal is carried out accordingly. <IMAGE>

Title: Hydraulic tool
Inventor: NORTHWOOD JOHN LESLIE
IPC: B25D17/06
Filed: 1983-08-26
Abstract: The invention relates to a hydraulic tool for delivering a controlled high power blow for instance to a corroded or abraded nut to split the nut. The tool comprises an accumulator 28, a cylinder 2 in which is a striking piston 1, and a bit 4. The striking piston 1 is moved away from the bit 4, latched to a piston 6, by hydraulic means. The accumulator 28 is supercharged by a supercharging piston 19 which subsequently releases the latch allowing the striking piston 1, under the influence of the supercharged hydraulic fluid in the accumulator 28, to move violently against the bit 4 thus delivering a very powerful blow to, for instance, a corroded nut. <IMAGE>
