Title: Improvements in or relating to coiling apparatus for use in rolling mills
Inventor: NORTH JOHN DUDLEY
IPC: B21C47/00
Filed: 1958-05-14
Abstract: 858,606. Rolling; coiling. BOULTON PAUL AIRCRAFT Ltd. May 11, 1959 [May 14, 1958], No. 15487/58. Class 83 (4). [Also in Group XXXV] The take-up roll 3 of a rolling mill is mounted so as to be movable under the action of the tension of the work 1 against the action of a spring 7 so as to apply a signal to a servosystem controlling the speed of the winding motor to maintain the tension of the work constant. The take-up roll 3 moves on a carriage 5 along a path inclined at 45 degrees to the direction of tension, the fluid spring 7 being charged by a pump 8 and an accumulator 9. A sensing device 11 is moved vertically downwards by an arm 13 attached to the carriage 5, as the coil diameter increases. The signal from the sensing device is amplified and applied to a torque motor 15 and control valve 16 to control the output of a delivery pump 17 supplying the hydraulic motor 4 driving the take-up roll. The speed is adjusted to maintain the position of the vertical tangent 18 to the roll and thus maintain the tension constant.

Title: Steroids and the preparation thereof
IPC: C12P33/00
Filed: 1956-05-18
Abstract: 3 - Keto - D 1,4 - steroids are obtained by contacting a D 4-steroid having from 18 to 21 atoms in the carbon skeleton with the dehydrogenating activity of an organism of the genus Nocardia, e.g. N. coeliaca, N. convoluta, N. corallina, N. crythropolis, N. gardneri, N. minima, N. polychromogenes, N. opaca and N. globerula. The process may be effected by bringing the steroid in aqueous solution or suspension into contact either with an actively growing culture of Nocardia, with cells of Nocardia removed from the growing culture and suspended in a suitable medium, or by contacting the steroid with extracts of dehydrogenating enzymes obtained from a culture of a species of the genus Nocardia.  Preferably the steroid is subjected to submerged aerated fermentation with a living culture of the organism.  As starting materials there may be used hydrocortisone, cortisone, corticosterone, Compound S, 14a -hydroxy Compound S, desoxycorticosterone, androstenedione, nortestosterone, 17a  - hydroxyprogesterone, 1 - ketoprogesterone, 9a  - fluoro - Compound F, 14a -hydroxy-Compound F, 11-epihydrocortisone, D 4,6 - androstadiendione, 11b ,17a  - dihydroxyprogesterone, D 14 - dehydro Compound S, testosterone, progesterone, 16 - dehydroprogesterone, D 9(11) - dehydro-Compound S, D 4 - pregnene - 17a ,21 - diol-3,20 - dione, D 4 - pregnene - 11b ,14a ,17a ,21-tetrol - 3,20 - dione and D 4 - pregnene - 14a , 17a ,21 - triol - 3,11,20 - trione.

Patent GB-780358-A (GB)
Title: Improvements in or relating to gas discharge tube circuit arrangements
IPC: H03K23/82
Filed: 1955-05-31
Abstract: 780,358. Electronic counting-apparatus. SIEMENS & HALSKE AKT.-GES. May 31, 1955 [May 31, 1954], No. 15614/55. Class 106 (1). In a circuit arrangement, e.g. for a counting chain, including a gas discharge tube, the anodecathode path of which is connected across a voltage source in series with a resistancecapacity combination and a rectifier so directed that at least part of the tube current flows through it in the forward direction, the rectifier comprises one arm of a potential divider, the other arm of which comprises an impedance (e.g. a resistance or rectifier) such that, if the potential of the voltage source is reduced, the residual voltage across the resistance-capacity combination will not produce any substantial reverse voltage between the anode and cathode of the tube. In the counting chain shown, comprising gas discharge tubes R1-R3 having control electrodes S1 to which pulses are applied through decoupling resistors from source G, and priming connections, comprising resistors W4-W6, between the cathode of each tube and a second control electrode S2 of the succeeding tube, the anodes are connected to voltage dividers comprising rectifiers such as G1, G4. If, e.g. tube R1 is conducting, the rise in cathode potential biases R2 whereby it is discharged in response to the next pulse from G. When the consequential sudden drop in anode voltage extinguishes R1, rectifier G1 prevents a harmful reversal in anode/cathode voltage ; and rectifier G4 prevents a sudden discharge of cathode capacitor C1 before tube R1 has deionized, so that the tube remains extinguished. A resistor and capacitor in parallel may be connected between rectifier G1 and. the anode of the tube, to compensate for the forward resistance of the rectifier ; the circuit values may be such that the capacitor is charged to half the maintaining voltage of the tube. In another form of chain (Fig. 5, not shown), the voltage dividers are connected to the cathodes and each comprise a rectifier connected in series with the RC circuit such as W12, C1, and a resistance connected to earth, the resistance having a low value compared with the reverse resistance of the rectifier.
