Abstract: 803,075. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd. Nov. 22, 1956 [Nov. 22, 1955], No. 33463/55. Class 38 (3). A traction system for supplying a D.C. motor from either a high voltage or a low voltage A.C. source comprises an auto-transformer 3, a transformer 2, and a rectifier 1, a change-over switch 9 being arranged to connect either supply to the transformer 3 so that the correct output voltage is fed to the transformer 2. As shown, the switch connects the high-voltage supply to terminal 8 and the low-voltage supply to an intermediate tap 7. In a modification, the tappings 6 on the transformer 3 are situated near the pantograph 4 which is connected directly to the winding 5, and the switch 9 connects to earth either the tap 7 or an end-terminal of the auto-transformer, Fig. 2 (not shown). The change-over switch may be either operated manually, or automatically through a signal when the vehicle passes from one voltage supply to the other.

Title: Apparatus for storing information
IPC: G05B19/07
Filed: 1971-09-28
Abstract: 1367760 Data stores NATIONAL RESEARCH DEVELOPMENT CORP 28 Sept 1971 [10 July 1970 10 Dec 1970] 33691/70 and 58730/70 Heading G4C An apparatus for storing sequences of signals includes a plurality of input terminals 10, 11, 12 connected to the write inputs 31, 32, 33 of bit stores 13, 14, 15 and, via delays 16, 17 and 18, to the address inputs 34, 35, 36 of the stores, the outputs of which are connected by feedback loops to the inputs of their associated delays. The arrangement is such that during the input to the stores of a sequence of words (one bit for each input terminal) the nth word after passing the delay addresses the stores for the input of the (n + 1)th word so that on read out a word appearing at the outputs of the stores (one bit per output) is fed back to the input of the delays, and, after passing the delays, addresses the stores so that the next word in the sequence is read out and so on. Two types of arrangement are described. In the first (as illustrated) m (the number of input terminals) = k (the number of stores) = n (where each store stores 2<SP>n</SP> bits) and the address lines 34, 35, 36 are connected as shown so that like bit stores in each of the stores 13, 14, 15 are addressed. Stores of this type, so called universal stores, are only capable of generating a sequence which has been fed to them since any address results in a word from the sequence fed in being outputted. In the second type, so called non-universal stores, Fig. 2 (not shown), m # k # n and the addressing connections are such that the bits of each word in an input sequence are stored in different, non-corresponding bit stores in each of the stores so that a random address fed in will produce an output sequence which depends on, but is not the same as the sequence fed in. In a further embodiment, Fig. 3 (not shown), additional control inputs are provided. The address inputs to the stores are connected as shown in Fig. 1 with the, or each, control input providing an additional address input for each store such that more than one sequence may be stored, each sequence being addressed by a particular combination of control inputs. In an example one control input is provided to address either a binary or a Gray code counting sequence. The apparatus is said to be applicable to the control of a sequence of operations by a machine tool or to perform Roget's Thesaurus (i.e. to provide similies of a given dictionary key word). In this latter case the sequences are rounded by linking the last word of a sequence to the first. The feedback loops are provided with switches 40, 41, 42, e.g. field effect transistors, to block the loops during input and prevent erroneous signals appearing at the outputs of OR gates 24, 25, 26.

Title: Steroid recovery process
IPC: C12P33/00
Filed: 1957-10-29
Abstract: Corticosteroids are recovered from fermentation broth wherein they are produced in a process which comprises filtering the mycelium, extracting the steroid into a water-immiscible organic solvent washing the resulting extract with an aqueous solution of a buffer at a pH of from about 7,5 to about 9,0, separating said buffer solution, concentrating the buffer washed solvent extract, adding to the concentrate an aqueous solution of a buffer at a pH of from about 7.5 to 9.0, cooling and stirring the mixture and separating the crystalline steroid compound.  As water immiscible solvent there may be employed methyl ethyl ketone, methyl isobutyl ketone, methylene chloride, ethylene chloride or cholorform.  Further purification may be effected by recrystallizing the steroid compound from a solvent system comprising a lower alkanol containing up to three carbon atoms and a water-immiscible solvent selected from methylene chloride, ethylene chloride and chloroform.
