Patent GB-794749-A (GB)
Title: Improvements in or relating to devices for indicating electro-magnetic or corpuscular radiation
IPC: G21K4/00
Filed: 1955-08-19
Abstract: 794,749. Photo-conductive devices. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 19, 1955 [Aug. 21, 1954], No. 23972/55. Class 37. [Also in Group XL (a)] The extinction or reduction of photo-conductivity by infra-red radiation is utilized in an electroluminescent radiation amplifier to convert either infra-red or X-ray images into visible images. In Fig. 1 a conductive glass plate 2 supports phosphor layer 3 of zinc sulphide activated by copper and a photo-conductive layer 5 of cadmium sulphide activated by silver and gallium, separated by an opaque layer 4 of black lacquer and enclosed between the conductive glass 2 and a transparent conductive coating 6, e.g. a thin layer of metal or of nickel oxide, or a further plate of conductive glass. An alternating voltage of frequency 500 c./s. is applied to the conductive parts 2, 6 and an infra-red image projected on to the photoconductive side of the device. An ultra-violet radiation from a lamp 12 is projected uniformly on to the photo-conductive layer and induces conductivity therein which is modified locally by the intensity of the infra-red image. The voltage variations produced thereby are impressed on the electroluminescent layer and give a negative invisible light of the infra-red image. Alternatively the photo-conductivity may be induced by particles or electrons instead of by ultra-violet radiation; e.g. by incorporating radio-active cobalt in the photo-conductive layer. In Fig. 2 (not shown), an X-ray image is projected on to the photo-conductive layer and infra-red radiation projected uniformly thereon in order to enhance the contrast of the visible image, the conductivity of the layer being reduced a greater amount by the infra-red radiation at those points where the X-ray intensity is lower. By controlling the area of infra-red radiation the contrast of various parts of the visible image may be varied at will.

Patent GB-834334-A (GB)
Title: Process of producing amyloglucosidase
IPC: C12N9/34
Filed: 1957-08-06
Abstract: Amyloglucosidase is produced by the submerged aerobic cultivation of Aspergillus phoenicis ATCC 13, 156 or A. phoenicis ATCC 13, 157 in an aqueous nutrient medium containing assimilable sources of nitrogen, carbon and nutrient minerals.  The strains of A. phoenicis are characterized by their ability to produce amyloglucosidase substantially free of alpha amylase.  Improved yields are obtained by (a) preparing an active vegetative inoculum of the micro-organism and (b) controlling the pH of the cultivation.  For (a) a sterile mixture of ground corn, corn steep water solids and starch in water of pH 7.0 is incubated with A. phoenicis ATCC 13, 156 for 24 hours at 30-35 DEG C. under aerobic conditions, the resulting vegetative culture is transplanted to a second broth which is incubated, agitated and aerated for 24 hours, the process being repeated on each of four more days, the 24-hour culture obtained from the fifth transfer being the activated vegetative inoculum.  For improved yields, the pH is controlled at 3.8 to 4.2 by the periodic addition of aqueous sodium hydroxide.  The carbon source may be white corn, potatoes, starch, ground oats, barley, wheat, corn syrup, dextrose or mixtures thereof; ground yellow corn in amounts of 5 to 15% by weight being preferred. Nitrogen sources are corn, oats, wheat, barley, ammonium sulphate, ammonium nitrate and sodium nitrate; ammonium sulphate in quantities of 0.1 to 2% being preferred. The magnesium source can be corn, oats, wheat or barley but magnesium salts especially the sulphate in proportions of 0.01 to 0.10% is preferred.  The preferred source of potassium and phosphorus is potassium monohydrogen phosphate in proportions of 0.01 to 0.20%.  The vegetative inoculum may be used in proportions of 0.5 to 10, and especially 1.0 to 2.0% by volume of the broth. Prior to inoculation the pH is adjusted to 5.8 to 6.2 and thereafter maintained at pH 3.8 to 4.2.  The temperature of incubation is 20 DEG  to 40 DEG  C. but preferably 30 DEG  to 38 DEG C., the duration 3 to 9, and preferably 5 to 7 days.  If not required for immediate use in the production of dextrose from starch (see Group VI), in which case clarification of the broth is not essential, the broth is filtered and the filtrate concentrated at 25 DEG  to 40 DEG  C.  The concentrate is stored at 3-10 DEG  C.
