Title: Magnesium low base number sulphonates
Inventor: CLEVERLEY JOHN ARTHUR
IPC: C07C309/04
Filed: 1996-02-27
Abstract: Magnesium low base number (LBN) sulphonates derived from high molecular weight sulphonic acids have low viscosity and are chloride free. The magnesium low base number sulphonates are not skin sensitisers. In their preparation neutralisation of high molecular weight sulphonic acids or partially neutralised soaps of high molecular weight sulphonic acids is completed by the use of a high base number sulphonate in conjunction with a carboxylic acid. The process does not require the use of chloride containing promoters and produces low chloride products.

Abstract: A thin film infrared emitter comprises electrically conducting diamond-like carbon in a freely suspended membrane or deposited on a substrate with low thermal capacity and diffusivity. On applying an electric current through the film, the latter is heated and emits infrared radiation. Topographic microstructures in the surface of the film influences the intensity of the radiation, its spectral characteristics and its polarisation state. The film is formed by deposition from gas or vapour phase on a substrate which in advance has been provided with embedded electric feed conductors. In embodiments of the invention with a self-supporting membrane the feed conductors also act as a support for the membrane after removing the substrate material by means of physical or chemical processes.
