Title: Improvements relating to extrusion presses
IPC: B21C35/04
Filed: 1959-12-18
Abstract: 904,671. Extruding. HYDRAULIK G.m.b.H. Dec. 18, 1959 [Dec. 22, 1958], No. 43171/59. Class 83 (4). In an extrusion process the extruded product 15 is separated from the discard 13 by inductively heating the product near the discard at 20 and applying a tensile force to constrict and finally rupture the product at the point of heating. The extrusion press has a ram 1 and dummy block 2 which extrude a billet through a die 12 mounted in a holder assembly 7-11, inclusive supported on a bolster 5. After extrusion, the product 15, Fig. 3, which may be a rod or tube, is supported on a roller table 16 and gripped by jaws 18 on a carriage 17. An inductor coil 20, Fig. 7, fed with high, medium or mains frequency current through an incandescent transmitter 19, then heats and softens the product and the carriage 17 is moved to the right to constrict and rupture the product. Simultaneously, ram 1 is withdrawn, Fig. 2 (not shown), an ejector plate 23 is placed thereon, and subsequently the container is moved to the left by driving plungers 6, to withdraw the separated end from the die and eject it together with the dummy block 2 and any residual shell 14, from the container bore. The extruded product is meanwhile withdrawn by the carriage 17. In another embodiment, Figs. 4-6, 8, 9 (not shown), the product is separated on the container side of the die after slightly withdrawing the container and introducing into the space provided a two-part inductor coil. Tensile force is applied during heating by the carriage 17 and/or by moving the container.

As shown, a pair of cutters 10 cut into the wire 11 leaving a residual portion 16 and causing a narrowing (12), Fig. 1 (not shown) of the wire in a plane at right angles to the plane of cutting. A second pair of cutters is then applied to the narrowed portion. Alternatively two pairs of cutters may be spaced longitudinally of the wire by the length of a pin and be applied simultaneously to different ends of a pin. The use of three or four pairs of cutters is contemplated. The cutters may be mounted, Fig. 5, to allow slight pivotal movement in the direction of arrow 26, i.e. in the general direction in which the pin 11<SP>11</SP> is caused to move by the action of the cutters, the stock 11<SP>1</SP> being held fast. The cutters are returned by springs 29. In an alternative form of cutter, Fig. 6 (not shown), the leading plane face is flanked by one divergent face and one face which is perpendicular to the axis of the wire.

The source/drain impedance of an FET is made to vary linearly with gate potential by connecting the substrate of the FET either directly or via an external capacitor to an intermediate point in an A.C. potential divider chain formed between the source and drain electrodes. An external capacitor is connected between the substrate and the gate electrode or separate external capacitors are connected between the substrate and the drain and source, respectively. In Fig. 2 the substrate of the FET 5 is connected to the potential divider comprising resistors 7, 8 and is also A.C. coupled to the gate electrode via capacitor 1. D.C. voltage source 3 controls the impedance R 2  presented by the circuit. In Fig. 5, resistor 8 is replaced by a parallel combination of resistors 17, 15, A.C. voltage source 14 and D.C. voltage 3, which is suitable for a modulator arrangement. The dividers of the previous figures can be capacitive as in Figs. 7, 9 (not shown) and these are suitable for H.F. work. The circuits can be used for gain control by connecting in the feedback paths of amplifiers or converters.

Abstract: 1481033 Magnetoresistive transducers COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 23 Oct 1974 [23 Oct 1973] 45967/74 Heading G5R An element I for use in a magneto-resistive read head has a magnetoresistive (MR) layer 1 arranged in a tunnel in a high permeability magnetic layer 2, 3 to which it is magnetostatically coupled, the easy axis A of layer 1 being at 45 degrees to a line joining an input E and an output S electrical terminal of the layer 1. The high permeability layer is formed by two sub-layers 2, 3 which touch one another on either side of the tunnel, and layer 1 is separated from sub-layer 2, 3 by electrically insulating non-magnetic layers 4, 5. The read head comprises a stack of such elements I, II with adjacent elements being magneto-statically coupled together at their edges and having their easy axes A, B at 90 degrees to one another. In the absence of an external magnetic field, the magneto-static coupling aligns the easy axes of the high permeability layers 2, 3 or 12, 13 of each element with the easy axis A or B of the corresponding MR layer 1 or 11, so that the vertical components Y of the magnetization vectors of layers 2, 3 are antiparallel to those Z of layers 12, 13. The effective reading window of a head having two such elements I, II separated by a non-magnetic, electrically conductive or non-conductive, layer 16 providing magneto-static coupling therebetween, is the sum of the thicknesses of layers 2, 3, 16, 12 and 13. MR layers 1, 11 may be of 300 Angstrom thickness permalloy, layers 2, 3, 12, 13 each being ten or more times as thick as each layer 1, 11 and made of iron-nickel or iron-nickel chromium. Layers 4, 5, 14, 15, may be of 1000 Angstrom thickness silica and layer 16 of 1000 to 3000 Angstroms thick silica. The head is produced by an evaporation process on a substrate with an electrically insulating protective layer on the side of the stack remote from the substrate.
