Patent GB-2244216-A (GB)
Title: Anti-microbial agent
Inventor: WRENCH ERIC
IPC: A61L2/00
Filed: 1991-05-30
Abstract: Glutaraldehyde is a useful anti-microbial agent, but is dangerous and unpleasant to handle and is thermally unstable. Despite these disadvantages, it is specified for use against bacteria in cooling towers of air conditioning plants of buildings and to control anaerobic sulphate-reducing bacteria in oil wells. The invention provides the bisulphite addition complex of an aldehyde or di-aldehyde, for use as an anti-microbial agent. The complex is less toxic than free glutaraldehyde. In cooling towers it slowly oxidises to the free di-aldehyde. In oil wells, its digestion by the sulphate-reducing bacteria releases the free di-aldehyde which controls the bacteria. In these ways, a more economic and environmentally safer use of anti-microbial additives is likely.

Title: Image analysis apparatus
Inventor: MACDONALD ALAN
IPC: H04N17/04
Filed: 1993-03-04
Abstract: Image analysis apparatus comprises a two dimensional array of photodetectors (80) for receiving light from pixels of a display screen (90). The intensity values generated by the photodetectors (80) in response to incident light from the pixels are stored in a memory (40). A processor (50) determines one or more performance parameters of the display screen (90) as a function of the intensity values stored in the memory (40) and of the distance between the centres of adjacent photodetectors in the array (80). Calibration and correlation problems associated with prior art measurement techniques, such as those mentioned earlier, are avoided by mapping the spacing of the array of photodetectors onto the known geometry of the display pixel structure. Also, the apparatus can be conveniently incorporated into a handset and therefore does not require complicated positioning jigs in use. <IMAGE>
