Abstract: 1,241,957. Yeast etc. BRITISH PETROLEUM CO Ltd. Nov. 12, 1968 [Nov. 27 1967], No.53744/67. Heading C6F. A micro-organism is cultivated in the presence of a petroleum fraction consisting wholly or in part of straight chain hydrocarbons, an aqueous nutrient medium and a gas containing free oxygen, the petroleum fraction and aqueous medium being continuously fed to a fermenter containing the micro-organism wherein takes place a first stage of cultivation of the micro-organism, a product stream comprising the micro-organism is continuously passed to a second stage fermenter wherein the micro-organism is treated with a second stage aqueous nutrient medium which consists of a mixture of all or part of the aqueous nutrient medium withdrawn from the first stage fermenter together with additional water, and a product stream comprising micro-organism is continuously removed from the second stage fermenter and treated to recover the microorganism, and in the first stage of cultivation the amount of essential nutrients in the aqueous phase in the first stage fermenter is such that the rate of growth of the micro-organism is not impeded by shortage of nutrients and in the second stage the amount of at least one essential nutrient in the aqueous phase in the second stage fermenter is less than the amount required for unimpeded growth of the micro-organism in the first stage of cultivation and/or at least one essential nutrient which is present in the aqueous phase of the first stage fermenter is absent from the aqueous phase of the second stage fermenter. The second stage aqueous nutrient medium may consist of a mixture of all or part of the aqueous nutrient medium withdrawn from the first stage fermenter together with 1-8 times the volume of additional water, sufficient to reduce any toxin produced in the first stage aqueous nutrient medium to a level insufficient to substantially impede growth in the second stage. The dilution rate used in the operation in the second stage fermenter should not be lower than that used in the first stage fermenter. An example is directed to a two-stage cultivation of Candida tropicalis upon a gas-oil, in the second stage of which the aqueous nutrient medium was deficient in potassium and phosphorus (as phosphate). The cultivated micro-organism may be extracted with n-pentane or n-hexane.

To prepare screen printing formes line-byline with a pattern having a motif repeated at least in the direction of the lines, the pattern motif 1 is photo-electrically scanned once lineby-line, and the resulting signals are fed via an analogue-digital converter 3 and coding member 4 directly to the control circuit 6 of an electromagnetically controlled engraving member 7 and to the reading-in head 12 of a store e.g. a disc store 8, switches 13 and 14 being closed while the first line of the first motif is engraved by member 7 on the printing forme and the corresponding first line signal read into store 8. To engrave the first line of the subsequent motifs switches 13 and 14 are opened and switches 9 and 15 closed so that the signal produced by reading- out head 10 is fed both to the writing-in head 12 and the control circuit 6. Consequently each line signal read-out by head 10 is written in by head 12 on disc 8, the distance between head 10 and 12 corresponding to a line signal. The control circuit 6 comprises separate circuits which are activated by different code words produced by member 4.

Abstract: 1,202,879. Electro-plating with aluminium. NIPPON KOKAN K. K. Dec. 21, 1967 [Oct. 25, 1967], No.58118/67. Heading C7B. A dense adherent non-dendritic protective coated of aluminium is electro-plated onto a metal object from a fused salt bath including aluminium chloride by adding to the surface of the bath a dehydrating substance which does not react with the bath components in sufficient quantity to allow plating to occur under moisture-free conditions. The dehydrating substance may be silica gel particles, silica granules, quartz sand, minute pieces of porous ceramics, an activated clay sintered to a granular form, diatomaceous earth, charcoal, graphite, carbon black, alumina gel particles, alumina particles, glass particles, glass fibres, asbestos, or powdered anorthite, calcium sulphate, fluospar zeolite, pumice or Japanese acid clay (a mixture of acid montmorillonite clay and soluble silicic acid) or mixtures of these substances. Typically the fused salt bath consists of aluminium and sodium chlorides in a 60:40 weight ratio, with optionally some potassium chloride, and the objects coated may be of steel, iron, copper or titanium. The quantity of silica gel added to a litre of the bath (1À7 kg) is typically about 1À7 weight per cent e.g. 30g, and the aluminium content is maintained by the use of an aluminium anode. Baths containing an excess of alumina may be regenerated by passing hydrogen through them and adding dehydrating agent.
