Title: Oxygenated steroid compounds
IPC: C12P33/00
Filed: 1954-11-17
Abstract: 21-Hydroxysteroids are prepared by subjecting a 21-desoxysteroid to the action, under aerobic conditions, of an oxygenating enzyme produced by an oxygenating strain of a microorganism of the family Sphaeroidaceae, particularly of the genera Wojnowicia and Hendersonia.  The oxygenation is effected either by growing the organism in a nutrient medium in contact with the 21-desoxy steroid, or by adding the steroid to homogenized resting cells which have been separated from the fermentation medium.  Suitable 21-desoxy steroids are pregnanes, pregnenes, allopregnanes, allopregnenes, bile acids and their esters, sterols and sapogenins.  In an example, D 4-pregnen-11b -ol-3,20-dione in dimethylformamide is added to a culture medium inoculated with Hendersonia acicola and after aeration and agitation of mixture for 48 hours it is sterilized and extracted with ethyl acetate, from which D 4-pregnene-11b ,21-diol-3,20-dione is isolated by chromatography.  Other examples describe the preparation of D 4 - pregnen - 11b ,21 - diol - 3,20 - dione; D 4-pregnene - 17a ,21 - diol - 3,20 - dione; D 4-pregnen - 21 - ol - 3,20 - dione; D 4 - pregnene - 11a , 21-diol-3,20-dione using the following organisms: H. herpotricha, H. phragmitis, H. rubi, H. aberrans and Wojnowicia graminis.  Other 21-desoxysteroids which can be hydroxylated are: D 4 - pregnen - 3b  - ol - 20 - one, 5,6 - dichloro - pregnan - 3b  - ol - 20 - one, 5,6 - dichloropreg - nane - 3,20 - dione, 5,6 - dichloropregnan - 17a  - ol - 3,20 - dione, D 4 - pregnene - 11a ,17a  - diol - 3,20 - dione, D 4 - pregnene - 11b ,17a - diol-3,20-dione, D 4 - pregnen - 17a  - ol - 3,11,20 - trione, pregnane - 3,11,20 - trione, and pregnan - 17a  - ol-3,11,20-trione.

Title: Improvements in or relating to installations for making x-ray photographs
IPC: H05G1/36
Filed: 1957-10-29
Abstract: 840,780. Measuring X-rays. NEDERLANDSCHE RONTGENAPPARATENFABRIEK N.V. Oct. 29, 1957 [Oct. 31, 1956], No. 33685/57. Class 40 (3). [Also in Groups XX and XXXV] The tube voltage is increased throughout a radiographic exposure so that the longer the exposure the higher the voltage at the end of the exposure. The mean voltage during exposure thus increases with increasing duration of exposure and the exposure timing means can thus automatically make the mean voltage equal to the voltage which would previously have been selected for an exposure of constant voltage. In the form shown, a photo-cell 40 receives light from a fluorescent screen to be photographed. A high secondary resistance in the transformer 1 enables the voltage of the X-ray tube 7 to increase when the cathode 5 is allowed to cool during the exposure. Prior to exposure, variable resistances 16 and 17 are included in the circuit of the cathode heater transformer 14. On moving exposure switch 26 to a pre-exposure position, contacts 24 and 27 are connected and relay 19 is operated to short-circuit resistor 17 and increase the heater current. The exposure is then initiated by closing timer contacts 28, and 29 and moving contact 24 to engage both 25 and 27. Relay 12 immediately closes contacts 11 to energize X-ray tube 7 and open contact 31 to deenergize relay 20 and decrease the cathode heater current by reinstating resistor 17. The exposure is terminated by firing of thyratron 42 and the operation of relay 22 to break contacts 21 and thus de-energize relay 12. Operation of relay 20 is prevented by holding relay which is not affected by contacts 21 so that the cathode heater current is not increased. On moving switch 26 back to the open position, relays 22 and 35 are de-energized and the circuit is ready for the next exposure operation. A clockwork timer may replace photo-cell 40 and condenser 41 which fire thyratron 42. The apparatus is stated to be operable without modification from a fluctuating mains voltage having a variable resistive load and the circuit component can be chosen so that the X-ray tube can never be over-loaded. Known means may be provided to prevent fluctuations in the voltage of the cathode heater circuit.

Abstract: 855,886. X-ray diffraction apparatus. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Oct. 23, 1958 [Oct. 26, 1957], No. 34006/58. Class 98(1) In an X-ray diffraction apparatus for examining a specimen at different temperatures, the specimen is supported in an evacuable chamber, and heated by means of electron bombardment of the support. In the apparatus shown, for the powder method of analysis, the specimen is in the form of a small rod 25, fixed vertically on a thin tungsten plate 24. This is supported from a few points only, so as to avoid conduction losses, on a cylinder 23 which acts as an anode co-operating with a cathode filament 29. When a potential difference of about 2500 volts is applied, the anode, and also the support plate 24 and hence the specimen 25, is rapidly heated by electron bombardment up to 2900 degrees in about 40 seconds. The anode is supported by a casing 12 secured on three pillars 10 attached to a main platform 2. Spring-loaded screws 14 on each pillar afford some lateral adjustment of the position of specimen 25. The casing 12 is so constructed that the whole anode structure, including the specimen, is rotatable on a ball-race 16, and is driven by a motor, which may be inside the vacuum chamber, at about 1 r.p.m. The apparatus is enclosed generally in an outer demountable casing built up of sections such as 48, 7, 1, bolted together. The casing may include watercooling channels 57, 58. The lowest section 1 is mounted directly on the vacuum pump (not shown) which may also serve to evacuate the X-ray tube itself (also not shown). The X-ray beam is directed through a channelled member 60 to strike the specimen, the remainder of the direct rays passing on through a further channelled member 61 into a trap 63. Surrounding the diffraction zone is a cylindrical window 36 of beryllium, through which the diffracted radiation passes to make a record on a sensitive film mounted outside the chamber. The film may be fixed, or may have a vertical movement for continuous recording. Heat radiation from the specimen may be conserved by reflection from metal mirrors 51, 54. A window 50 is provided for observation of the specimen, and determination of its temperature by an optical pyrometer.
