IPC: H02M7/525
Filed: 1961-08-24
Abstract: 958,948. Inverting. GENERAL ELECTRIC CO. Ltd. Aug. 24, 1962 [Aug. 24, 1961], No. 31917/62. Divided out of 958,947. Heading H2F. [Also in Division G3] The electric inverter system described in Specification 958,947 includes a series output voltage regulator, the impedance of which increases if the output voltage falls to an abnormally low value, e.g. under short circuit conditions. The output voltage is automatically maintained constant under normal conditions by a series transductor 56 having a control winding 60 which is energized by an error signal derived from a circuit including transistors 73, 76. The output voltage is applied to the primary winding 66 of a transformer 65; a voltage proportional to this output voltage is derived from a secondary winding 68, is rectified and smoothed, and is applied over a potentiometer 72 to the base of transistor 73 which, together with a reference Zener diode 74 acts as a comparator to deliver an error signal which is applied by way of transistor 76 to the control winding 60, whereby the impedance of transductor 56 is varied in dependence upon output voltage variations. If, however, the output voltage falls to a very low value, positive feedback provided by a winding 59 causes the impedance of transductor 56 to increase, whereby a finite load impedance is presented to the inverter which is thus protected against an excessive load current. The feedback winding 59 is connected to a rectifier circuit 63 so that it is energized by a rectified portion of the output of the inverter system. A circuit utilizing silicon controlled rectifiers may replace the transductor' 56. Specification 857,775 also is referred to.

Title: Therapeutically active substances and method of obtaining such substances
IPC: A61K35/74
Filed: 1935-11-19
Abstract: Active substances, specific for the decomposition of foreign proteins of diseased tissues of the body, are obtained by growing proteolytic micro-organisms on proteins of the types to be decomposed and extracting, from the products of the growths, liquids which contain the active substances.  The process is described by reference to the treatment of carcinoma tissue and the lenses of pigs which become cataractous shortly after their removal and are therefore to be regarded as equivalent to diseased living tissue.  The tissue in question is placed in a liquid culture medium, e.g. NaCl solution and inoculated with a culture of proteolytic bacteria, e.g. B. subtilis, B. histrolyticus, B. prodigiosis, B. proteus.  After a sufficient time, e.g. 24 hours and upwards, the active preparation is separated by centrifuging and filtration.  The preparation may be adjusted by acidification or alkalinization.  Treatment of sarcomatous and tuberculous tissue is also referred to.
