Title: Process for diamond growth
Inventor: KNAPP WILHELM
IPC: C01B31/06
Filed: 1986-04-11
Abstract: A "process for diamond growth" at temperatures of about 750 DEG C improved by the J. B. Hannay method, but using atmospheric pressure and decomposition of chemically pure CH4 instead of petroleum spirit (benzine, petrol). Additionally using Mg2SiO4 or MgNi2SiO4 or MgFe2SiO4 preferably Li4SiO4 as catalyst instead of Li. The same in the form of clusters, and also as paracrystals. The growth diamonds are placed on a catalyst cooled with liquid O2 and whose surface has been baked together by laser irradiation; with the growth diamonds exciting the C atoms by means of the irradiation with carbon-arc lamps. As a result of the decomposition temperature of the CH4 being reduced by the catalyst, the life time of the excited C atoms is extended, with the addition path being in the range of molecular vibrations as a result of the direct irradiation of the growth diamonds. Since the carbon-arc lamps burn in a CH4 or C2H2 atmosphere, the H atoms in the crystalliser are also activated by the spectral lines of the H atoms. In the excited state, the H forms no intermediate products in the crystalliser.

Filed: 1988-02-26
Abstract: For the purpose of applying HTSC material to workpieces by thermal spraying, ceramic powder having superconductive properties is employed as the starting material, and after spraying the superconducting properties are regenerated by a controlled (systematic) heat treatment. According to the invention, the quality and, in particular, the bond strength of the HTSC layers on various substrates is improved by a high spraying wattage being employed during thermal spraying. In a high-speed flame-spraying process, the spraying wattage is chosen to be >/= 100 kW for a mixing ratio of oxygen to propane of from 5:1 to 7:1. If the process used for thermal spraying is a plasma spraying process, the spraying wattage is >/= 50 kW.

Title: Bicycle drive having stepless power transmission/gear-shift mechanism, which can subsequently be mounted on any bicycle frame and is intended for installation in vehicles prepared for this purpose
IPC: B62M1/24
Filed: 1988-09-20
Abstract: The drive used in the invention permits stepless gear-shifting both during freewheeling and under load. All bicycle frames can subsequently be equipped with the drive. Apart from the rear wheel, the front wheel can be driven together with the rear wheel or alone. Multi-track land vehicles and watercraft and aircraft can be driven with one drive shaft. As a result of the longer lever arm of the pedal levers, the swivelling angle limited to 90@, the avoidance of co-rotating parts in the drive, and the steplessly controllable power transmission, better power utilisation and thus a higher efficiency are achieved than can be achieved by means of a crank drive having hubs or a derailleur gear shift mechanism. <IMAGE>
