Title: Improvements in or relating to the production of sodium-penicillin
IPC: C07D499/16
Filed: 1944-09-20
Abstract: Sodium-penicillin, characterised by a moisture content less than approximately 2.0 per cent and by high stability, is obtained by subjecting this compound as ordinarily obtained to severe drying conditions, e.g. exposure to high vacuum, in the presence of anhydrous calcium sulphate, magnesium perchlorate, or preferably phosphorus pentoxide, for 24-48 hours at room temperature.  In an example: sodium-penicillin solution, obtained by standard methods from culture media carrying selected strains of Penicillium notatum, is frozen and subjected to high vacuum, prior to further drying in a vacuum desiccator over phosphorus pentoxide until the moisture content of the salt falls to about 0.5-1.3 per cent.

Abstract: 530,458. R÷ntgen ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). June 23, 1939, No. 18380. [Class 39 (i)] An X-ray tube has (i) a cathode enclosed in a common single envelope with an anode comprising a tubular element of high heat conductivity with one portion extending within and another outside the envelope, tubular element being divided by a transverse wall to form an electron-receiving and a cooling chamber, (ii) an X-ray producing target on the transverse wall, (iii) an X-ray transmitting window adjacent to the wall, this window being of a material containing a large proportion of an element of an atomic number of thirteen or less. As shown in Fig. 3, the vacuum-cast copper tubular member 10 has a tungsten target 16 in the transverse portion 12. The aperture in the wall of the tubular member is covered by a beryllium plate 28 seated in the recess 26 and secured by an annular ring 64 screwed into the tubular member. Alternatively, the plate may be secured by a ring joined by screws to the tubular member 10, as shown in Fig. 5. A second similar window 72 may be clamped to the sealing cup 68 by means of a ring 74.
