Abstract: 1,112,201. Transistor logic circuits. WESTINGHOUSE ELECTRIC CORPORATION. 7 Oct., 1965 [29 Oct., 1964]. No. 42602/65. Heading H3T. The output transistor of a logic circuit has its input connected in parallel with a further transistor which controls a semi-conductor device such that it provides a surge of current to the output circuit when the output transistor is cut off. When, any of the input signals is at earth potential transistor 44 conducts and the output is at earth potential. When all inputs become positive, transistor 44 is cut off. Transistor 43 is also cut off allowing 52 to conduct and so to charge rapidly any load-capacitance 60, e.g. of succeeding logic stages. The values of the biasing resistors are chosen such that when the capacitance has charged, transistor 52 becomes non-conducting.

Treatment of Sirodesmins A, B or C with methanolic HCl gives the corresponding desacetyl derivatives, having the Formula (I) wherein n is 2, 4 or 3 respectively and both R<SP>1</SP> and R<SP>2</SP> are hydrogen in each case. Conversely, treatment of Sirodesmins A, B or C with acetyl halide or acetic anhydride gives the mono-acetate of each compound, having the Formula (I) wherein n is 2, 4 or 3 respectively and both R<SP>1</SP> and R<SP>2</SP> are acetyl in each case. Further reactions include (a) treatment of Sirodesmin A with triphenylphosphine in chloroform to give Sirodesmin monosulphide having the Formula (I) wherein R<SP>1</SP> is acetyl, R<SP>2</SP> is hydrogen and n is 1; (b) treatment of Sirodesmin A with sulphur in the presence of an organic base and a solvent to give a mixture of Sirodesmins B and C; (c) treatment of Sirodesmin B and/or C with thionyl chloride in an organic base to give Sirodesmin A; and (d) treatment of the antiviral complex with SO 2  in pyridine giving a further new antiviral compound Sirodesmin J. Sirodesmins D, E, F, G, H and J are identified by their N.M.R. values in deuterochloroform and their I.R. spectra in liquid paraffin. Their molecular formulae are thought to be as follows: Sirodesmin D: C 20 H 26 N 2 O 8 S x  where x is probably 4; Sirodesmin E: C 20 H 26 N 2 O 8 S x  where x is probably 3; Sirodesmin F: C 20 H 26 N 2 O 8 S x  where x is probably 3; Sirodesmin G: C 20 H 26 N 2 O 8 S 2 ; Sirodesmin H: C 20 H 26 N 2 O 8 S x  where x is not defined; and Sirodesmin J: C 20 H 26 N 2 O 8 S 2 . The various Sirodesmins are separated from each other by chromatographic techniques. The Sirodesmins A-J and the antiviral complex containing them are admixed with pharmaceutically acceptable dilents or carriers to provide antivirally active pharmaceutical compositions.

Abstract: 928,887. Electric positional control. CLYDE CRANE & BOOTH Ltd. Nov. 30, 1960 [Dec. 22, 1959], No. 43483/59. Class 40 (1). Apparatus for controlling the operation of a crane, e.g. its bodily movements, crab or jib movements, or movements of the crane hook, comprises a positional control system including manually operated control means and means for developing an error signal if the load on the crane is incorrectly positioned in relation to the setting of the control means, the error signal being used to control the field of a unit controlling the driving motor(s) of the crane whereby said motor(s) operate(s) to nullify the error signal and to position the load correctly. As shown, a control handle 6 is connected through gearing and a clutch 18 to the rotor of a selsyn transmitter 17, the rotor of the selsyn receiver 16 being connected to a crane driving motor 1. When the switch 2 is in its upper position, an error signal developed in the rotor of transmitter 17 consequent upon misalignment of the two rotors is amplified in a transistorised amplifier 9 and used to control the field of a Ward-Leonard generator 11 supplying the motor 1, which latter operates to position the load and the rotor of receiver 16 in accordance with the setting of handle 6. Feedback from the Ward Leonard generator to the amplifier limits the armature current in the motor. One or a pair of potentiometers may replace the selsyns in the error signal circuit; for example, a series of push-button switches each associated with a potentiometer setting may replace handle 6. When switch 2 is in the position shown, the motor 1 is operated by the main control arrangement which involves comparing the output of a tachometer generator 7 driven by motor 1 with a speed reference voltage obtained from a manually operated control unit 8, and feeding the difference into amplifier 9. An A.C. driving motor system may alternatively be used.
