Title: Strip looper device
Inventor: O'BRIEN JEREMIAH WAGNER
IPC: B21B41/10
Filed: 1962-11-19
Abstract: 1,058,087. Automatic tension control. UNITED ENGINEERING & FOUNDRY CO. Nov. 1, 1963 [Nov. 19, 1962], No.43717/62. Heading G3R. In a system for automatically controlling tension in strip material passing between two units, tension is applied by a strip-deflecting member moved against a resistance such as a dashpot by a linkage so arranged that the tension is substantially independent of the deflection. As in Specification 989, 059, the tension in strip material passing between two units, e. g. stands of a rolling mill, is maintained constant and the tension is determined by the force applied by a looper device engaging the strip between the units. The tension is made independent of the extent of deflection of the strip by suitable design of a linkage through which a fluid-pressure device acts on the looper device, and the weight of the looper device is balanced out by further means. In Specification 989,059 the fluid-pressure device was hydraulic whereas in the present Specification it is pneumatic to give quicker response, any undesirable oscillation being avoided by coupling a hydraulic damper. Fig. 2 shows a plan view of rolls 12 and back-up roll 13 of one rolling mill stand. A deflection force is applied to the issuing strip (not shown) by a looper roll 15 which is movable in a substantially vertical arc by rotation of a shaft 19 to which it is attached. Torque is applied to shaft 19 through a suitable linkage by a pneumatic actuator 32 to which a constant pressure is applied and movements are damped by a hydraulic dashpot 33 coupled by an identical linkage. A further pneumatic actuator 35 cancels the otherwise unbalanced weight of the looper arrangement. The three fluid-pressure devices are trunnion mounted in a frame 29 which is adjustable about shaft 19 by a motor (not shown) to suit any change in the location of the pass line of the strip. The pneumatic and hydraulic devices 32, 33 may be arranged mechanically in series. Use of a balance weight instead of actuator 35 is referred to. Tension may be measured by means associated with dashpot 33.

Abstract: 1,019,490. Transistor blocking oscillators; circuits employing bi-stable magnetic elements. HONEYWELL Inc. Nov. 3, 1964 [Nov. 4, 1963], No. 44847/64. Headings H3B and H3T. A monostable circuit comprises a magnetic core having one winding connected to a switch and which in response to a pulse sets the core to one state and a second winding connected to a further switch which when the core is set causes it to be reset, the switches being maintained non-conductive when they are not being used respectively to set or reset the core so that unwanted conduction does not occur if the pulse is unnecessarily long. In the circuit shown, the input pulse is differentiated and the resulting spike turns transistor 21 on. Current accordingly flows in the " set " winding 12 and feedback to winding 13 maintains the transistor conducting until the core 10 is saturated. Transistor 21 then becomes non-conducting and the voltage induced in winding 15 causes transistor 36 to conduct until the current it passes through the " reset " winding 14 causes the core to saturate in the reverse sense, whereupon feedback to winding 15 terminates and the transistor becomes non-conducting. The reduction in the magnetic field produces a voltage across winding 13 but this is opposed by a voltage induced in a winding 12 and transistor 20 is not turned on again. In Fig. 3 (not shown) the input pulse is applied to transistor 35 and transistor 50 is of the S.C.R. type, the opposing winding being omitted. The supply for the S.C.R. is obtained from a capacitor 59 which stores sufficient energy to reset the core but insufficient to maintain the S.C.R. conductive thereafter.

Arithmetic unit 202 (Fig. 16). All data and information transferred between elements of the processor go through the arithmetic unit which includes A and B registers 1,603, 1,604 the A register being used for move-type instructions. In response to an address applied to AROM 1,602 control signals are applied to arithmetic and logic unit 1,601 and to gates in the arithmetic unit 202. In addition operations, carries to the next byte are held in flip-flop 1,607, a carry from the last byte resulting in flip-flop 1,636 being set. An all-zero signal on destination bus 205 is detected by gate 1,613, 1,614 and results in flip-flop 1,607 being set. Any non-zero byte results in the flip-flop being reset and it cannot then be set during the current arithmetic operation.

Abstract: A process for preparing caprolactam by the catalytic rearrangement of cyclohexanone oxime in contact with solid catalysts at elevated temperature and in the presence or absence of an inert gas, is characterized in that the gas mixture leaving the reaction chamber is quenched by liquid caprolactam, and the subsequent condensation of caprolactam is effected in a column equipped with baffles, a low boiling liquid being added at the top of the column.  Reaction is conducted at 210-450 DEG  C., at a pressure from 10 mm./Hg up to 1 at. gauge.  Suitable catalysts are phosphoric or boric acids, heteropolyacids, alkali metal bisulphates, or mixtures thereof; they may be incorporated on a carrier, e.g. alumina (which may be calcined), silica gel or TiO2.  Steam is a suitable inert gas. Specified low-boiling liquids are water, C1- 4 alkanols, C3- 5 dialkylketones, C5- 7 alkanes or benzene. The temperature difference between the gas leaving the reaction chamber and the caprolactam should be at least 10 DEG  C., and the column should contain sufficient baffles to prevent loss of caprolactam vapour.

Abstract: 1524693 Removing radioactivity from hydrocarbons SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 5 Nov 1975 [7 Nov 1974] 45915/75 Heading C5E The radioactivity level of a stream of hydrocarbons is reduced by the removal of radioactive metals or compounds thereof by passing the stream at 100-400 C. through a solid or liquid contact material at a space velocity of 0À1 to 100 Kg per hour per litre of space filled by the contact material.
