Title: Plasma assisted diamond synthesis
Inventor: WORT CHRISTOPHER J H
IPC: H01L21/31
Filed: 1992-06-26
Abstract: ABSTRACT   The invention relates to a method of forming a plasma for assisting in the production of a ceramic material such as diamonds. The method includes the steps of providing a bell jar, and introducing a selected gas into the bell jar.The gas may comprise an active gas such as hydrogen, and a gaseous carbon compound. A beam of microwave radiation is generated from a remote source, and is focused using an array of lenses or mirrors to a focal region within the reaction chamber so as to form a plasma in this region. The shape of the plasma is independent of the inner profile of the chamber and dependent on the geometry and position of the focusing array. A substrate is located within the reaction chamber, and the plasma interacts with the substrate so as to cause chemical vapour deposition of, for instance, a plasma activated carbon component of the plasma onto the substrate. The invention extends to apparatus for use in the method.

Title: Method of plastic forming
Inventor: UEHARA TADAYOSHI
IPC: B21J5/06
Filed: 1991-07-18
Abstract: ABSTRACT OF THE DISCLOSURE        A method of plastic forming in which a blank in the die undergoes plastic deformation with the advance of a punch whose moving speed is controllable. Deformation of the die incurred by an impact caused when the punch strikes the die is prevented by slow advance of the punch until the die touches the blank. When the punch comes into contact with the die, the pressure to move the punch forward, while interfering with the advance of the punch, is raised to a limit at which plastic deformation occurs. The advance speed of the punch is controlled so that, with release of the pressure having interrupted the advance of the punch, distortion speed of the blank may be made substantially uniform almost throughout the area subjected to plastic forming. Uniform stress acting on the die as a result of uniformized distortion speed of the blank leads to a uniform amount of deformation of the die almost throughout area subjected to plastic forming, whereby lowering of precision in forming caused by fluctuations in the deformation amount of the die is prevented. With the pressure of ejecting means made relatively higher than that of the punch at the time of ejection, spring-back of the die is prevented by ejection of the blank under pressure.

Title: Shut-off valve
Inventor: CLARE MANAMOHAN
IPC: F16K43/00
Filed: 1993-06-08
Abstract: The invention provides a quick-acting shut-off valve for hydraulic installations, particularly for pressure balanced mixing valves such as might be used in a shower/tub installation. The shut-off valve includes a casing mounted to the installation housing adjacent an inlet port thereof, there being a reciprocable actuator sealingly retained within the casing for direct movement between first and second positions. The actuator carries a valve member at a distal end thereof for sealingly blocking the inlet port when the actuator is in its second position. When the actuator is in its first position the inlet port is open to normal water flow therethrough. The actuator utilizes a simple push-on, push-off ratchet mechanism to effect movement between the two operating positions thereof. The shut-off valve is readily accessible for quick operation and, when the installation needs repair, it is not necessary to locate a master control valve to terminate water flow to the installation, thereby maintaining water flow to other installations in the same hydraulic circuit.
