Title: Improvements relating to the production of wear-resistant surface layers
Inventor: LANCASTER JOHN KEITH
IPC: C21D1/38
Filed: 1958-10-24
Abstract: 893,231. Heat treating metals. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 16, 1959 [Oct. 24, 1958], No. 34168/58. Class 72. [Also in Group XI] A process of producing a wear resistant surface on a metal article comprises depositing a surface layer of wear resistant material on the article, using the article as the cathode in an electrolytic bath, and briefly subjecting each part of the surface to a high energy electric discharge produced across a gas or vapour envelope that is formed at the surface. The layer may be a metal, e.g. W, Vi, Cr, Ta, Ni, or an alloy of Ni, Cr, 13., or may be a lubricant, e.g. molybdenum disulphide or graphite, and may be applied by spraying or electrodeposition. As shown, the article 3 having a layer 4 is made the cathode in an electric circuit comprising a source of power 11, a condenser 6, and an anode 9, the article and the anode being immersed in an electrolytic bath, e.g. a solution of sodium carbonate in water. When the condenser is discharged a gas envelope 13 forms on the surface of the article opposite the anode and a high energy discharge takes place across the envelope. In a modification, Fig. 2 (not shown), a continuous discharge is used and the surface of the article is scanned by an apertured plate so that each part of the article is subjected to the discharge. Specifications 893,232 and 893,233 are referred to.

Title: Semiconductor devices
IPC: H01L23/522
Filed: 1965-08-13
Abstract: 1,113,344. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 13 Aug., 1965 [20 Aug., 1964], No. 34866/65. Heading H1K. In a semi-conductor device comprising an inclusion of one conductivity type in the surface of a region of the opposite type the inclusion is surrounded by a metallic layer in contact with said region and having a portion spaced from the surface of and extending inwardly over part of the region to shield it from electric fields which might cause inversion at said surface and give rise to leakage paths. A typical transistor of this type, shown in Fig. 3, comprises a P + silicon substrate with an epitaxial P layer in which base and emitter regions and a P + guard ring have been formed by successive diffusions of phosphorus and boron through oxide masking. The shield electrode 43, which in this case extends from the guard ring, is formed of chromium or molybdenum. Silica is pyrolytically deposited from an oxysilane compound to form a layer 38 on which the extended emitter and base contacts 40, 39 are formed by evaporating metal over the entire surface and then etching it to the desired form. The guard ring is optional and the emitter and base contacts need not extend over the oxide layer. In the latter event the pyrolytically deposited silica layer is unnecessary. In a further embodiment, Fig. 11 (not shown), a P + guard ring used to isolate a resistor and a transistor formed within adjacent N-type inclusions at one surface of a P-type body is provided with a shield electrode which extends over the junctions between the guard ring and the adjacent body material. In a similar arrangement, Fig. 10 (not shown), in which the resistor and transistor are formed within P-type inclusions in an N-type boly, isolation from the body is effected by N + rings and associated shield electrodes within the inclusions and surrounding the resistor and base region of the transistor respectively. Finally, in an assembly consisting of transistors formed by diffusion in an epitaxial N layer on a P substrate and mutually isolated by diffused P + walls extending through the epitaxial layer, a shield electrode extends along the walls to protect the parts of the layer adjacent the walls (Fig. 12, not shown).

IPC: H01R13/41
Filed: 1956-11-17
Abstract: 815,135. Binding-posts. WINGROVE & ROGERS Ltd. Nov. 7, 1957 [Nov. 17, 1956], No. 35213/56. Class 38 (1). A lead-through or stand-off insulated terminal, comprising a central conducting pin having a roughened medial portion connected to a portion of reduced diameter by a tapering portion and an insulating sleeve surrounded by a metallic collar, is mounted by inserting the sleeve and collar in a panel hole and forcing the centre pin into the sleeve so as to expand the collar and lock the assembly in the hole. The metallic collar 12 has a flange 12b which abuts the panel 13 a smaller flange 12c having chamfered sides by which it is retained in the panel, and it is split to enable it to expand. The insulated sleeve 11 may be of a plastic such as polytetrafluorethylene and as a flange 11a which abuts the flange 12b of a collar 12. The central pin 10, which may be of brass, has a narrow portion 10c, a tapering portion 10d and a knurled or roughened portion 10b. On assembly the sleeve 11 and collar 12 are inserted into the hole in the panel 13 and then the pin 10 is forced through the sleeve 11 until a flange 10a on the pin 10 abuts the flange 11a. The expansion of the sleeve 11 at 11b prevents it being withdrawn and the pin 10 is retained by the roughened surface 10b. The ends of the pin 10 may be screw threaded and provided with nuts or drilled to constitute sockets; for use as a stand-off insulator one end may be shortened.

Filed: 1938-12-03
Abstract: 522,039. Autographic registers. FANFOLD, Ltd. (United Autographic Register Co.). Dec. 3, 1938, No. 35289. [Class 106 (i)] In an autographic register with a supply compartment, a platen, a record compartment, means for feeding folded strips over the platen, and means for directing a strip into the record compartment has the supply end of the platen disposed at or near to one end of the record compartment and extends from its said supply end over the record compartment. A voucher strip 15 and record strip 16 pass from a supply compartment A<SP>1</SP>, over a platen A<SP>3</SP> to crank-operated feed rollers 30, 31 whence the voucher strip issues past a cutting edge 28 to the outside of the machine while the record strip is directed downwardly past a fixed cutting edge 19 into a storage compartment A<SP>2</SP>. Perforations in the strip co-operate with the rollers to determine the extent of feed and align the weakened folds of the strip in alignment with the cutting edges. The operating crank is given two rotations at each operation and is controlled by a detent that is manually disabled at the beginning of the operation and disabled by a cam at the end of the first cycle. Re-folding of the strip is ensured by an oscillating guide 45 and by a pair of cam-actuated clamping members 55, 62, the forward clamping member 55 being raised out of contact with the strip and behind a shield 61 during each operation,' while the rearward clamping member 62 is raised during alternate operations. To assist in correctly loading the machine, a verticallymovable slide 44 is cam-operated to indicate whether the leading form should bear an even or an odd number. The partition 9 between the supply and storage compartments is removable to increase the size of the supply compartment when no record is to be stored in the machine, thus permitting the use of a strip having more distantly spaced folds or the insertion of two connected packs of voucher strip.

Abstract: 800,580. Velocity-modulated tubes. WESTERN ELECTRIC CO., Inc. Dec. 13, 1955 [Dec. 14, 1954], No. 35740/55. Class 39(1). [Also in Group XL(c)] A velocity-modulated tube has an input means, such as helix coupler 74, Fig. 4, an interaction region, such as travelling-wave helix 72, a collector 71 and, between the interaction region and the collector, a region 80 along which the field varies periodically to focus on the collector electrons having predetermined velocities and to defocus other electrons. As shown the field is magnetic with pole-pieces 81, excited by coils or permanent magnets to give a series of spatially alternating fields and this produces the velocity-collector current characteristic shown in Fig. 2b characterized by pass bands 31, 32, 33 with "stop bands" between them. By working at a mean voltage such as X a velocity-modulated beam 36 gives an asymmetrical collector current 37 having a rectified component. The same arrangement may be applied to a klystron. Instead of simple detection of an input signal, the device of Fig. 4 may be used as a pulse generator (see Group XL(c)), the cathode 63 being pulsed, and the auxiliary radio-frequency input from source 92 being adjusted so that a negative pulse is obtained at collector 71, this being recirculated, with delay, to maintain a repetitive pulse sequence.
