Filed: 1958-10-14
Abstract: 843,075. Drawing wire. AJAX MANUFACTURING CO. Oct. 14, 1958, No. 32812/58. Class 83 (4). In a method of drawing wire, the wire is gripped against backward movement and a series of drawing dies are moved in succession along the wire in a sequence starting with an end die of the series. The wire 11 is held against movement to the right, as shown in the Figure, by a wedge-type gripping device 13 and is operated upon in turn by dies 17, 18 and 19 in carriers 14, 15 and 16 which are moved to the right in that order by cams 57, 64 and 80 acting upon pivoted levers 41, 42 and 43 which engage the die carriers. The return strokes of the carriers are effected by springs 68, 74 and 88. Each carrier body 31 has a chamber 33 for a drawing compound and a guide tube 34 for the drawn wire. The cams are spaced 120 degrees apart and shaped so that the drawing stroke of the carrier 15 begins as that of the slide 14 ends, and so on. Elongation of the wire due to the drawing strokes of earlier dies is taken up by later dies moving away from their operating levers so that only the latter part of the movement of those levers produces a drawing stroke of the later dies. After the operating strokes of all the dies, the wire is fed forward by feed rolls and the slides 14-16, under the action of springs 48-50, move with the wire to their original positions.

Title: Improvements in or relating to magnetic devices
IPC: G11C11/06
Filed: 1953-11-30
Abstract: 738,362. Electronic counting-apparatus. BURROUGHS CORPORATION. Nov. 30, 1953 [Dec. 3, 1952],No. 33217/53. Class 106 (1). [Also in Group XXXIX] A magnetic device comprises one or more magnetic circuits, each including a core portion of a material having substantial magnetic remanence, inductive winding means, a capacitance in circuit with at least one of the winding means and a discharge path for the capacitance through the whole or part of that winding means. In a first embodiment a core 15 is assumed to be in a state of negative remanence and a core 16 in a state of positive remarence. Positive input pulses applied via a conductor 12 tend to drive both cores to positive remanence. The winding 14 offers a relatively small impedance to the first pulse, the core merely being driven further into positive saturation, and therefore a relatively large charge is acquired by a capacitance 11. At the termination of the input pulse the capacitance 11 discharges through the winding 14, providing sufficient current to drive the core into a state of negative remanence. The winding 13, on the other hand, presents a relatively high impedance to the first input pulse, sufficient current passing through the winding, however, to drive the core into a state of positive remanence. The capacitance 10 does not acquire a sufficient charge to disturb the state of the core at the termination of the input pulse. Thus successive input pulses repeatedly reverse the opposite states of the two cores 13, 14. In another embodiment a centre-tapped winding 55, Fig. 6, on a single core 63 is connected to an input wire 54, as shown. When the core is in the state of remanence to which an input pulse tends to drive it, a capacitor 56 acquires a charge sufficient to reverse the state of the core by discharging through the lower section of the winding 55 and a resistor 570, upon termination of the input pulse. On the other hand, the high impedance presented by the winding 55 to an input pulse driving the core from an opposite state of remanence, prevents the capacitor from acquiring an effective charge. In a further embodiment (Fig. 3, not shown) a pair of cores similar to that shown in Fig. 6 are connected in parallel for operation from a single input. It is also stated that the upper terminal could be earthed and input pulses applied at the lower, previously earthed, point. Fig. 5 shows a series of two-state cores similar to that of Fig. 6 connected to form a scale-of-eight binary counting chain. In the embodiment shown in Fig. 4 an integral member 41 acts as two core members, an air gap being provided in the central limb to prevent permanent magnetization.

A method of producing pipes of a desired length comprises roughly severing the continuously produced pipe into lengths which are a multiple of the final length required, the roughly severed blanks being moved transversely to a severing machine where the blanks are rotated and cut into the finally desired lengths. The end-members 1, 2, Fig. 1, and the carriages 5, 6, 7, 8, are adjusted along the connecting bar-members 3, 4 to receive the tube and be in the correct severing positions respectively. The long tube is roughly severed from the continuously produced tube and is fed in on runways 32 to a temporary position 35, Fig. 3, in the present dividing machine. The tube is moved to a position supported by adjustable rollers 11, 12, for severing, these rollers are provided on the carriages and may be driven by gearing. Complementary rollers 13 carried by slides 14<SP>1</SP> in the carriages hold the tube on centre. The rollers 13 are resiliently mounted and the slides 14 also carry severing and chamfering tools. The severing tool 14, Fig. 2, is adjustable and the chamfering tool 15 is held retracted by an electromagnet 20 until a definite depth of cut has been reached. The magnet is then released and a spring 31 feeds the tool to make the chamfer. The rough ends of the pipes are held by chucks 28, Fig. 1, driven by motors 28<SP>1</SP>. The severed lengths of tube are moved transversely to rollers 20 driven by motors 20<SP>1</SP> or placed in an inclined arrangement to remove the tubes longitudinally. Specification 924,523 is referred to.
