Title: Improved aerobic fermentation process
IPC: C12P19/42
Filed: 1958-01-10
Abstract: In an aerobic fermentation process in which a culture of a micro-organism is added to a nutrient medium, the nutrient medium is first sterilized by the addition of hydrogen peroxide, catalase is then added to the medium and finally a culture of the micro-organism and the fermentation proceeds under conditions suitable for the growth of the micro-organism, additional hydrogen peroxide being added continuously throughout the fermentation to provide oxygen for the micro-organism.  Further nutrient medium sterilized with hydrogen peroxide may be added to the broth as fermentation proceeds. The process may be employed in the production of (a) vitamins such as B12 and riboflavin; (b) antibiotics such as penicillin, streptomycin, tetracyclines e.g. chlortetracycline and oxytetracycline, and bacitracin; (c) citric acid; and (d) oxygenation of steroids, particularly p  11-dehydrocorticosterone to cortisone and progesterone to 11-hydroxyprogesterone.ALSO:In an aerobic fermentation process in which a culture of a microorganism is added to a nutrient medium, the nutrient medium is first sterilized by the addition of hydrogen peroxide, catalose is then added to the medium and finally a culture of the microorganism and the fermentation proceeds under conditions suitable for the growth of the microorganism, additional hydrogen peroxide being added continuously throughout the fermentation to provide oxygen for the microorganism.

Title: Improvements in and relating to variable speed gearing
IPC: F16H33/10
Filed: 1939-01-13
Abstract: 595,866. Variable-speed gear. EASTON, R. W. Jan. 13, 1939, No. 1171. [Class 80(ii)] A variable-speed gear is controlled automatically by the gyroscopic resistance of two pairs of flywheels S mounted in a freely rotatable drum on spaced axes mutually at right-angles and at 45 degrees to aligned driving and driven shafts D, E, which latter each carry bevels A, engaging stepped radial bevels B, C, which engage bevel pinions on the flywheel shafts. Relative rotation between driving and driven shafts spins the flywheels S and rotates them bodily about the axes of the shafts D, E thus developing a variable resistance which eventually overcomes the load. Reference has been directed by the Comptroller to Specifications 107,251, 221,725, [both in Class 80 (ii)], 414,693 and 455,963.
