In assembly, the terminal 15, crimped to the wire 14 is inserted into the body and the rod 21 is screwed into the threaded hole in the terminal. The assembly 12 is then inserted over the rod and held captive to unit 11 by nut 22, so that a seal is formed between the plug and socket, the shield layers 19, 24 connecting. Further assemblies are added by screwing a further rod into the nut 22 &c. The assembly is terminated by the plug 13, the semi-conducting layer 26 being optional.  The insulation material may be of elastomeric ethylene-propylene terpolymer. Air pockets at the plug and socket junctions may be removed by providing across the junction a removable wire as a temporary escape path and insulating dielectric grease may be provided over the plug and socket surfaces. The terminal unit 11 may be provided with a plug member rather than a socket, and the position of the succeeding modules is then reversed.

Abstract: 1,161,724. Inspecting steel strip magnetically and photo-electrically. GILLETTE CO. Oct. 13, 1967 [Oct. 14, 1966], No.46736/67. Headings G1A and G1N. In the manufacture of razor blades the steel strip is inspected for defects during the tempering and sharpening processes, and a defect is marked with a magnetic spot for subsequent detection and rejection of the marked section. The defect sensors may also actuate counters and trigger indicator flash-lamps. Defects which may be sensed are:- (i) "sweep" (curvature in the plane of the strip) by a gimbaled roller carrying a mask to vary a light beam relative to a photo-electric cell (unit (18), Fig. 2, not shown); (ii) "dish" by a vacuum head connected to a differential-transformer-vacuum-sensor (unit (20), Fig. 2); (iii) "burrs" by direct electrical contact, (unit (22), Fig.2); (iv) "width" by mechanical contact actuating an air valve, (unit (24), Fig. 2); and after sharpening by the masking of a light beam Fig. 6 (not shown) (v) "welds" by a thickness feeler actuating a switch Figs. 7a, b (not shown), to provide a magnetic mark which is subsequently detected and the welds removed (vi) "edge" i.e. quality of the honed facet by light scattered from the facet. (vii) flaws in steel detected by a "gauss meter". Edge detector Fig. 5a (not shown) a parallel beam of light shines through a masking slit on to the blade edge and a photo-multiplier and associated optical system senses light scattered at an angle of 60 degrees to the parallel beam, (the half angle at the blade tip being 28 degrees). A second detector views the other facet about 8" along the strip. The light beams are chopped by a slotted disc to provide an A. C. signal, and may be derived from a single bulb by prism reflectors Figs. 5b, 5c (not shown). Associated circuitry for processing the sensor signals, triggering the indicator flash-lamps power supplies &c. is described with reference to Figs. 8. . 10 (not shown).

Title: Improvements in or relating to magnetic coincidence stores
IPC: G11C7/02
Filed: 1965-11-08
Abstract: 1,122,293. Circuits employing bi-stable magnetic elements. SIEMENS A.G. 8 Nov., 1965 [9 Nov., 1964], No. 47216/65. Heading H3B. In a coincident current thin magnetic film matrix store the sense conductor extends in one direction parallel to the easy axis across half of the storage cells of a row and across the remaining half of the cells of the row in the opposite direction along the easy axis. As shown in Fig. 1, a plurality of anisotropic thin films are arranged in a matrix on a metallic, non-ferromagnetic support and drive conductors X, Y, positioned as shown to define the storage locations. In operation a read pulse is applied to the selected Y conductor and after a time sufficient to allow the noise voltage induced in the sense conductor 5 to dissipate a second pulse is applied to the selected X conductor, Fig. 2 (not shown). At the same time as the X-pulse is applied the read out amplifier connected to transformer 6 is energized. If a " 1 " is stored the output is in the form of a bi-polar double pulse whereas in the case of a " 0 " a small negative pulse is produced. In the subsequent write operation the Y-pulse is kept on and the X-pulse is either positive or negative dependent upon whether a " 0 " or a " 1 " is to be written. The Y-pulse and then the X-pulse are switched off at the end of the cycle. Noise signals induced in the sense conductor due to current in the Y conductor are minimized by giving the Y current a long build-up period and employing the wiring arrangement of the sense conductor as shown in Fig. 1, wherein induced voltages cancel out. Noise signals due to capacitive coupling between an X-conductor and the sense conductor 5 are minimized by employing a metallic support member 2 connected to the X conductors and positioning the sense conductor as near as possible to the support while keeping the X-conductors as far away as possible. Noise signals due to half-energization of cells on a Y-conductor are compensated for by the wiring arrangement of the sense conductor. The magnetic thin films may be a continuous layer and the conductors may be formed by printed circuit techniques.
