Title: Method of and apparatus for the production of seamless tubes of uniform wall thickness
IPC: B21B17/04
Filed: 1974-02-19
Abstract: 1442492 Rolling tubes SUMITOMO METAL INDUSTRIES Ltd 19 Feb 1974 [2 March 1973] 7446/74 Heading B3M A seamless tube of uniform wall thickness is produced by piercing an ingot, rolling the resulting product in an elongator mill, e.g. a multi-stand mandrel mill, to provide a tube having end portions of relatively thin wall thickness, and rolling the tube in a stretch reducing mill to produce a tube of constant wall thickness. By thinning the tube ends, the normal thickening experienced in a stretch reducing mill is compensated for. The mandrel mill may have eight stands in tandem, of which the fifth and sixth are adjusted to thin the tube at its leading and trailing ends. A suitable stand, Fig. 5, has upper and lower roll clocks acted on by hydraulic screwdowns 8<SP>1</SP>, 8<SP>11</SP>. Threaded adjustable compression rods 11<SP>1</SP>, 11<SP>11</SP> restrain movement of the chocks. A main load cell 12, and further cells 13<SP>1</SP>, 13<SP>11</SP> associated with the rods, produce output signals which are fed to electrical control units 14<SP>1</SP>, 14<SP>11</SP>, 15<SP>1</SP> and 15<SP>11</SP> for maintaining the roll gap constant irrespective of changes in rolling load. The rods 11<SP>1</SP>, 11<SP>11</SP> allow the wall thickness of a tube to be adjusted, but for thinning the ends of a tube being rolled, a control signal is fed to the control unit 14<SP>1</SP> to vary the settings of the screwdowns 8<SP>1</SP> and 8<SP>11</SP>. The rolls are equally adjusted to avoid differences a wall thickness at opposite sides of a tube, and to maintain the pass line constant. In place of the mandrel mill, a multistand plug mill or pilger mill with additional stands for rotating the tube may be employed.

Title: Improvements in and relating to the production of synthetic threads, fibres, filaments and like filamentary materials
Inventor: RAKOWSKI LECH
IPC: D01F6/72
Filed: 1951-04-04
Abstract: Preformed polythiourea threads are stretched at least 450 per cent. in the presence of a swelling agent and at an elevated temperature in such a manner that the extensibility of the stretched thread is at least 15 to 25 per cent. and then annealed without allowing them to retract.  The threads are considered to be annealed when they do not shrink more than 6 per cent. when heated in air for 20 minutes at 70 DEG  C. in freely relaxed condition.  Water is the preferred swelling agent.  The stretching may be preferably effected in stages using known stretching devices.  The annealing is carried out in a heated atmosphere after removal of the swelling agent, for example by drying when the swelling agent is water.  In an example a hexamethylene polythiourea thread is stretched 513 per cent. in water at 65 DEG C. in three stages, and then dried by passage over a heated roller. It is then annealed by heating at constant length while wound on a bobbin for one hour in air at 70 DEG  C. and then for a further hour at 90 DEG  C.  Specifications 524,795, 534,699 and 660,905, are referred to.

Title: Improvements relating to electric selective systems
IPC: H04Q3/42
Filed: 1945-03-28
Abstract: 589,726. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and LONG, D. P. March 28, 1945, No. 7866. [Class 40 (iv)] In a system in which a selector, e.g. a counting switch, hunts for a position marked by another selector, e.g. a register, over a translating field common to a number of selectors of both kinds, agreement in position between a pair of selectors, one of each kind, completes a circuit over the translating field and an individual relay winding, in which an induced current can flow, but which does not include any source of current. The invention is described with reference to a register controller of the kind described in Specification 573,885. On the operation of contact S1 to initiate the sending of the first digit, relay M pulls up and a self-interrupting circuit is made for P which at each operation energizes PA and the magnet CS of the counting switch. Each operation of PA releases M. The circuit of the high-speed stop relay SZ is thus held open until the contact marked by the register W1 is reached, whereupon an induced impulse in the right-hand winding of M, which occurs when its left-hand winding is disconnected by the energization of PA, delays its release so that it is still operated when P falls back. SZ is then energized before PA falls back, locks up and terminates the digit. Subsequent digits are similarly controlled. To prevent delay in the release of M when connected up in series with a similar relay in another sender, a rectifier MRA is included in the circuit of its right-hand winding. Specifications 462,773 and 471,987 also are referred to.
