Title: Improvements in electrochemical machining
Inventor: BROWN DENNIS COCKBURN
IPC: B23H9/02
Filed: 1964-12-14
Abstract: 1,137,061. Electro-chemical deburring of metal workpieces. ASSOCIATED ENG. Ltd. Dec.10, 1965 [Dec. 14, 1964], No.50852/64. Heading C7B. In a method of deburring metal workpieces by electro-chemical machining in which a deburring tool is arranged in close proximity to the region or regions to be deburred such that the tool and workpiece are maintained in fixed positions during the deburring operation, the tool and the workpiece being connected into an electrical circuit such that the workpiece forms an anode and the tool forms a cathode, electrolyte being present therebetween, the tool employed is shaped so as to conform to the shape of the region or. regions to be deburred. The tool may be formed using as pattern a workpiece which has been deburred, either by casting metal about the workpiece and removing therefrom said casting which thus conforms to the workpiece, or by means of a reverse electrochemical machining process in which the workpiece forms the cathode and a tool blank forms the anode. The tool may be partially coated with insulating material to restrict electrolytic action to the required regions, Fig. 3 (not shown). In the apparatus shown for carrying out the method of the invention a gear-wheel 18 which forms the workpiece to be deburred is mounted on a base 19 and within an enclosure 23, the deburring tool 21 being mounted above said workpiece, and electrolyte is supplied to the enclosure via pipe 25 to pass through the gap 22 between the tool 21 and workpiece 18 to discharge via outlet 27. A desired pressure may be maintained within the enclosure by means of pressure valve 28. After the deburring operation has taken place compressed air may be admitted to the enclosure via inlet 30 to blow out electrolyte from the enclosure and partially dry the workpiece.

Abstract: 1393337 Mono-crystalline films INTERNATIONAL BUSINESS MACHINES CORP 15 Nov 1973 [29 Dec 1972] 52952/73 Heading B1S Single crystal films are grown on a substrate by depositing an amorphous film of a crystallizable material on the substrate at a temperature below the crystallization temperature of the material forming the film and heating the film to propagate from a seed crystal a mono-crystalline phase throughout the material of the film. Two or more films of monocrystalline materials may be formed on the substrate. The film may in certain cases be stripped from the substrate. The seed crystal may be a substrate which promotes epitaxial deposition or a portion of such a substrate, or the seed crystal may be formed in situ from a portion of the amorphous film and propogated throughout the remainder of the film by passing a hot zone across the film from the seed crystal. The film may be applied as a pattern to the substrate which may be inert and the seed formed at a peripheral part of the pattern e.g. where it comes to a point The substrate may be a single crystal of Gd 3 Ga 5 O 12  or Sm 3 Ga 5 O 12  with an amorphous portion of SiO 2 , a quartz substrate or a plastic support from which the monocrystalline film can be stripped.

Abstract: 1,145,442. Blind riveting; crimping. SCOVILL MFG. CO. 28 Nov., 1967 [30 Nov., 1966; 2 Nov., 1967], No. 54082/67. Headings B3Q and B3U. A fluid-operated power tool comprises a cylinder 10 in which three pistons 26, 30 are slidably mounted in three chambers defined by plates 22. The pistons are spaced by cylindrical spacers 23 and the spacers and pistons are held together by a hollow tie rod 17. One end of the tie rod has a nut 16 screwed thereon which is slidable in a guide 13 mounted on the cylinder by split rings 15. The mandrel of a blind riveting assembly can be secured to the tie rod. In operation compressed air is admitted by a valve in the passage 39 to the annular manifold between the spacers and the tie rod. The fluid flows through gaps 31 between the spacers and recesses 36a, 36b, 36c in the pistons into the chambers. The plates 22 are not secured to the cylinder wall and are forced against split rings 15 by the air. The recesses 36a, 36b, 36c get progressively larger to admit equal quantities of air to each chamber. The rearmost piston abuts a resilient buffer 42 when the mandrel breaks. The valve is then moved so that the chambers may exhaust under spring bias 37. In an alternative embodiment the tool acts leftwards under air pressure and is returned rightwards under spring bias. The tool has a fixed anvil 52 and a crimping or clinching hammer 51. Alternatively the tool may have double-acting pistons and a valve 61 to supply air to either side of the pistons. To move the hammer against the anvil air is supplied through a passage 55 to the annular manifold. To retract the hammer air is supplied along passage 59 to the left of piston 30.

To obtain a substantially uniform coolant outlet temperature over the entire exit face of the core the temperature of the coolant supplied to different parts of the inlet face may be caused to be different by a number of ducts 46 connected to a phenum chamber 44 supplied with hot coolant through pipes 41, 42 and a pump 40. The coolant from the ducts 46 mixes with the coolant that has passed through the perforated lower wall of the shroud 29.
