Title: Improvements in the application of coatings of enamel and other material to rectangular wire
IPC: C23D5/02
Filed: 1947-02-13
Abstract: 621,265. Coating wires. BRITISH INSULATED CALLENDER'S CABLES, Ltd., and KRETSCHMER, J. M. [Representative of KRETSCHMER, H. E.]. Feb. 13, 1947, Nos. 4139 and 8062. [Class 140] A die for use in coating a rectangular wire 1, Fig. 4, with enamel, comprises four elements 11, 12, 13, 14, each consisting of a group of thin metal plates placed side-by-side in planes parallel with the die axis and in which the operative surface of each element is formed with projecting ribs, the four elements being resiliently held together to permit the elements to follow irregularities of the wire surface. The ribs in the surface of each element are formed either by sharpening the edges of the plates or by making some of the plates project. The ribs need not be in straight lines and the channels between the ribs may be of different cross-section. The ribs may be arranged to allow increased flow of enamel near the rectangular corners of the wire. In a further modification, Fig. 6, parts of the die elements 11 and 13 are cut away to form recesses 36 and 39 and these recesses in conjunction with surfaces 35 and 40 permit the die elements to move inward without mutual interference.

Abstract: 1300096 Voltage dependent resistors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Jan 1970 [1 Feb 1969] 4358/70 Heading H1K A voltage dependent resistor comprises a one grain thick layer 1 (Fig. 3) of zinc doped gallium phosphide in a polyurethane binder 3; the grains projecting in either side of the binder and layers 4, 5 of aluminium being applied to contact the projecting parts. The electrode layers 4, 5 (Figs. 1, 2) each comprise two rows of islands 4A, 4B, to 4F, 5A, 5B to 5F located on opposed sides of the grain layer; each island 4B to 4F partially overlapping consecutive islands 5A to 5F and vice versa. Islands 4A, 5F have aluminium layer or wire conductors 6, 7 attached thereto, between which two sequences of series connected sections 8 of the grain layer interposed between the overlapping parts of islands 4A to 5F are connected in parallel. The current/voltage characteristics (a) between conductors 6/7 and (b), between opposite islands over a single region 8, are given (Fig. 4, not shown) and non-linearity is obtained from the non-linear metal/semi-conductor contact junctions between the electrode layers and the grains. A selected intermediate island 4 (Fig. 1) has a metallic layer tapping 9 connected to a further voltage dependent resistor formed by electrode 10, the grain layer, and an opposed electrode 11. The grains may be of N-type conductive silicon, and the granular layer may be ionically bombarded; after which the aluminium layers are vapour deposited over a mask and the contact formed by a short initial current pulse between the layers. In a modification (Fig. 5, not shown) the non-linear characteristic is obtained by PN junctions in silicon grains having a highly doped P-type core partially surrounded by an N-type layer and a P-type layer; the electrode layers respectively constituting ohmic contacts with the core and with the outer P-layer. A single coherent electrode layer on each side of the granular layer provides an asymmetric characteristic, while a series combination for even number of regions provides a symmetric characteristic. Other semi-conductor grains and electrode materials may be used.

Abstract: 751,475. Angular bending. BABCOCK & WILCOX, Ltd. Feb. 19, 1954 [Feb. 19, 1953], No. 4742/53. Class 83 (4). Apparatus for hot bending metal tubes includes a rotary former to which the tube is attached and around which the tube is bent, and electric induction heating means arranged internally of the tube to heat the narrow zone of tube being bent as the zone moves along the tube. A straight pipe 1 is positioned between a former 13 and a reaction roller 14, which are grooved, Fig. 2, so that the bases of the grooves are not engaged by the pipe. An induction heater 16 is positioned inside the pipe between the former 13 and roller 14 and the end of the pipe fitted over a flange 6 of an hydraulically actuated cross-head 2. A supporting shoe 7, slidable in a guide 10, is secured to the pipe and the pipe is secured at 32 to the former 13. The pipe is then pushed longitudinally by the cross-head 2 to rotate the former 13 and thus bend the pipe, the bent pipe being cooled by air from a nozzle 22. The induction coil 16 is carried by a lance 18, comprising concentric copper tubes, and it and the lance are water cooled. A radiation pyrometer 23 measures the temperature of the hot zone. The induction heater 16 may be positioned nearer one side of the pipe than another. The former 13 may be controllably braked, to keep the temperature of the hot zone constant, Fig. 6 (not shown) or driven in the direction in which it is rotated by the cross-head and such. drive may be sufficient to carry out the bending without the application of drive to the pipe. According to the Provisional Specification the former may be water cooled and have a ceramic insert, relay means may control the rate of movement of the tube and the cross-head 2 may be advanced by motor-driven screw means.

Title: Improvements in or relating to electrical time circuit arrangements and oscillation generators
IPC: H03K4/12
Filed: 1935-02-14
Abstract: 452,017. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, and YOUNG, A. J., 61, Galveston Road, Putney, both in London. Feb. 14, 1935, No. 4793. [Class 40 (v)] A valve employed for the sudden discharge or charge of a condenser in a relaxation oscillator, or for other high-speed non-mechanical switching, is associated with two other valves in such a way that when the first is conductive the other two are nonconductive and vice versa, the third valve being back-connected to control the first. As shown, the condenser 1 is charged in known manner through a screen-grid valve 4 from a voltage source connected across the terminals 2, 3, and is suddenly discharged through a resistance 11, and a triode valve 12. As the discharge starts, the plate of the valve 12 becomes less positive in voltage and this voltage change is transferred through a condenser 15 to the grid of the second valve 17. The current through this valve is thereby reduced. Its path includes the space between the screengrid and the cathode of the third valve 24, shunted by a high resistance 22 which may be omitted. The reduction of the screen-grid current of the pentode valve 24 causes a reduction of its plate current through the variable resistance 26, and thus increases the conductivity of the first valve 12, which has its grid connected to the plate of the third valve 24. Thus when the discharge of the condenser 1 has once started it is accelerated by the action of the valves 17, 24. The discharges may be synchronized by impulses applied to a grid of the pentode valve 24 through a condenser 31 and a tapped resistance 30. In a modification, Fig. 2, (not shown), the valve 12 is a tetrode with. its plate connected directly to the condenser 1, and with the resistance 11 in the circuit of its outer grid. In another arrangement, two triodes with grids connected are substituted for the valve 12, one serving to discharge the condenser directly, the other providing resistance-capacity coupling to the next valve 17, Fig. 3 (not shown).

Abstract: 1,211,415. Cleaning and slitting gizzards. GORDON JOHNSON-STEPHENS Ltd. 30 Jan., 1968 [9 Nov., 1967], No. 4805/68. Heading A2U. A method of cleaning and slitting gizzards of birds comprises applying jets of pressurized liquid (e.g. water) to the internal walls of the gizzard to clean the gizzard before slitting the gizzard open. In the apparatus shown a gizzard attached to the bird by a connecting strand is fed by hand towards vertically reciprocable plate 11, the strand being guided by guides 32, 33. The strand is engaged and pulled by neck 36 of horizontally reciprocable member 13 so that the gizzard is drawn on to the plate 11 which is moved upwardly so that the gizzard is jammed between plate 11 and a plate 17a on intermittently moving roller conveyer 14. The member 13 is then reversed in movement and knife 37 thereon cuts the strand to free the gizzard. As the conveyer 14 is moved the gizzard is forced by element 18a on plate 17a along the plate 11 and on to tube 26 which passes through the gizzard. As the gizzard is moved along pipe 26 it is internally cleaned by jets of pressurized water from apertures 38, slit open by saw toothed rotating disc 12, and further cleaned by jets from apertures 40. The gizzard may then have its inner skin removed. The movements of conveyer 14, member 13 and plate 11 may be controlled by pneumatic cylinders 23, 54, 31 or other mechanical means, the sequence of movements being initiated when plate 34 is tripped by the gizzard or the hand conveying the gizzard towards plate 11. The plate 11 and element 18a have co-operating undulating surfaces.
