Title: Method and apparatus for cold forming shaped metal articles
IPC: B21J5/10
Filed: 1972-11-09
Abstract: 1408447 Forging nuts F GURBIN 9 Nov 1972 [9 Nov 1971] 51639/72 Heading B3H A shaped article with a through opening, such as a nut, is made by forging a metal blank of the same volume as the article in a die cavity by impact from a punch 7 to cause the blank to expand and fill the cavity. The metal displaced by the punch is forced outwards to form part of the article and not discarded as a slug. The blank is fed from a magazine into an aperture on the outer annular holder 56 of a turntable 5, Fig. 5. The turntable is axially movable against spring bias 22 so that the descending punch 7 causes the holder 5b to abut against a supporting ring 6 which forms the lower surface of the die cavity. Two blanks are fed from two magazines to two adjacent apertures in the turntable and the forging is effected simultaneously on two blanks at station 28, Fig. 7. The blanks are cut from a bar stock (32), Fig. 8 (not shown) by a pair of blades 31. A burr removal station 29, Fig. 7, has a pair of punches 13 which are forced through the apertures of the forged article, Fig. 3 (not shown). The forged articles are ejected in pairs by a pair of plungers (15), Fig. 4 (not shown), at a discharge station 30, Fig. 7. The shearing, forging, deburring and discharging apparatus are provided between an upper platen 23 and a lower platen 21 and are mounted between the platen of a press for actuation. The article may be a weld nut with a flange or a cap nut with a blind bore.

Title: Methods of manufacture and magnetic transducers made thereby
IPC: G11B5/39
Filed: 1972-11-14
Abstract: 1395059 Magnetic transducers INTERNATIONAL BUSINESS MACHINES CORP 14 Nov 1972 [20 Dec 1971] 52477/72 Heading G5R A magnetic transducer is formed from a laminate 20 comprising at least two foils or sheets, one of magnetic material forming a core portion, and one of conductive material 24 forming a winding, the foils being shaped by subtractive processes, preferably photo-etching, or possibly cutting by laser or electron beam, or mechanical cutting. As shown, the laminate 20 comprises a conductive foil 24 between two magnetic foils 22, 26, is supported by a non- conductive substrate 28, and is etched to produce parallel, single-turn, U-shaped heads 20a. The magnetic foils 22, 26 are joined in the backgap area by a deposited magnetic layer 32 or a shim, or by pinching the foils together. The heads are then mounted in a housing to produce a multi-track read/write head, Fig. 1. In alternative embodiments, Figs. 5, 6 (not shown), the magnetic foils (22, 126) are not co-extensive and are not joined in the back-gap area, and utilize no substrate. A magnetoresistive element (236), insulated from the magnetic foils by a layer (234), provides for magneto-resistive playback with a magnetic bias field provided by an adjacent member (238). If a two-foil laminate is used, having only one magnetic foil, the core is completed before or after shaping by a deposited magnetic layer or a magnetic foil. A multi-turn winding may be made by etching the initially exposed conductive foil in the shape of a coil. Laminates of more than three foils may also be used to provide multi-turn heads, or read-after-write heads with intermediate shielding. Multiple magnetic layers are separated by insulation to reduce eddy currents, but insulation from the winding is not essential because of the disparity in conductivities. The laminates are initially constructed by co-rolling foils and then annealing. Preferred magnetic foils are of alloys of Fe, Ni, Mo, while preferred conductive foils are of Cu, Ag, Au and their alloys.
