Title: Working or shaping of diamonds - by heating with carbon-dissolving metal pattern
IPC: B28D5/00
Filed: 1979-06-11
Abstract: Working of diamonds is carried out by contacting the diamond with a suitable pattern at 600-1800 degrees C. under conditions such that the diamond and the pattern are at the same temp. The pattern is made of a metal or alloy capable of dissolving carbon from the diamond at the working temp. The process is carried out in vacuo, in an inert gas atmos., or in a gas which does not react with diamond but does react with the dissolved carbon at the working temp. The process can be used, e.g. to engrave, cut or bore diamonds for the prodn. of monocrystalline diamond tools or jewellery. The diamonds can be worked with high precision without the need for complicated equipment or procedures.

Title: Apparatus and method for separating mixtures of chemical substances
IPC: C01B31/02
Filed: 1992-02-25
Abstract: The invention describes the apparatus and the method for separating mixtures of chemical substances by means of a closed form of liquid chromatography in which the eluent, having left the chromatographic installation, and having been purified by evaporation, is returned to the inlet point of the chromatographic installation. A mixture of substances which are eluted very slowly can thus be separated efficiently and on a large scale without a large amount of eluent being required for this purpose. Preparative separation of a mixture of fullerenes thus produces very pure C60 (greater than 99.9%) and C70 (greater than 99%) in high yield.

Abstract: Thermal-radiation imaging devices, elements and systems are described. The device comprises on a substrate (2) e.g. of sapphire semiconductor bodies or body portions in the form of parallel elongate strips (1), e.g. of cadmium mercury telluride. Biasing-electrode means (6 and 7) e.g. of gold are spaced on the strips (1) for causing a bias current predominantly of majority charge carriers to flow along each strip (1). The bias current supports an ambipolar drift of radiation-generated free minority carriers in the opposite direction.
