Title: Improvements in machines for severing metal strips
IPC: B23D15/00
Filed: 1958-05-09
Abstract: 838,573. Making electrical connectors; shearing; jointing by stamping. AMP Inc. May 9, 1958 [May 31, 1957], No. 14893/58. Classes 83 (2) and 83 (4). A machine for severing a metal strip comprises a shear plate and a shear blade mounted for relative reciprocating movement. to sever the strip on the closing stroke, means. to move the strip axially. so that the severed end projects over the shearing edge of the plate, means to hold the strip against axial and transverse movement after the axial movement and means on the blade to burnish the severed end on the opening stroke. A strip of taper-pin electrical connectors 6 are fed to an anvil 4 where a ferrule-forming portion 8 is crimped about the end of a conductor by a resiliently mounted die 14 carried by a ram 16 reciprocable relative to abase. Spaced shear plates 18, 20 co-operate with a shear blade 22 carried by the ram to shear out a link 30 between the two leading connectors, slightly before the crimping operation but after the portion 8 is lightly engaged by the die 14. The crimping operation causes slight axial extrusion of the connection e.g. 0.015 inch so that the trailing end overhangs the shear plate 18 and extends into a recess 36, Fig. 5, in the shear blade 22. On the upstroke of the ram the camming surface 38 on the shear blade 22 burnishes the end of the crimped connector and bends any burr or stump upwards. During burnishing, the die 14 and a hold-down plate 68 which bottoms on the base are held down by the pressure of springs 60 and 78 and the extent of the burnishing may be adjusted by governing the release of the holding action of the die 14 by means of a screw 52 (not shown). Shoulders are formed in the ferrule-portion 8 during crimping which assist in axially holding the connector during burnishing.

Title: Process and apparatus for making laminated sheet materials
IPC: D04H13/00
Filed: 1946-05-17
Abstract: 621,867. Compound sheet materials. SYLVANIA INDUSTRIAL CORPORATION. May 17, 1946, No. 14933. Convention date, May 17, 1945. [Class 140] Laminated material is made by interposing a porous mat of unwoven fibres between a pair of preformed solid synthetic resin films, and causing the material of one or both films to flow through the mat and unite with the other film, e.g. by heating. One or both films may be supported on a temporary backing sheet which is stripped from the laminated material after its formation. Stripping may be facilitated by cooling the combined sheets. The mat may be formed from cotton, hemp, jute, flax, kapok, wool, hair, fur, silk, asbestos, glass fibres, rock wool, casein, gelatin, zein, or viscose rayon fibres, or may be made wholly or in part from thermoplastic fibres of higher melting point than the films, such as cellulose esters and ethers, vinyl polymers or copolymers, polyvinylidene chloride, or nylon. The fibres may be carded, and one or more carded webs used as the mat, or the carded web made into slivers or strands which are arranged side-byside or crossed to build up a mat. Alternatively, fibres a may be formed or dispersed in a gaseous atmosphere in a chamber 24 by means of a spray-gun 25 and settle to form a mat on the surface of a synthetic resin film B<SP>6</SP> carried on an endless belt 12a, a second synthetic resin film B being united with the other layers between heated rolls 16. Alternatively a warp of continuous filaments may form the mat. A second warp may be placed across the first layer to give strength in two directions. The films may be of thermoplastic synthetic resin or thermosetting resin in the thermoplastic stage. Resins specified are polyvinyl and polyacrylic resins, polystyrene, polyvinylidene chloride, polythene, synthetic rubbers such as polybutadiene, olefine polysulphides, neoprene, polyisobutylene, thermosetting resins such as urea-, phenol-, or sulphonamidealdehyde resins, and alkyd resins. A minor proportion of short fibres may be included in the films. To facilitate adhesion, a solvent or plasticizer for thermoplastic fibres in the mat or the film may be incorporated in the fibres or the film. Several fibrous mats may be combined with a larger number of films so that films are on the outer surfaces of the final product. The films may contain resin, wax, asphalt, mildew- or fire-proofing materials, or colours. The films may be embossed or printed before, during, or after laminating. The product may be used for wrapping, or making bags or tubes.

Abstract: 1488216 Overvoltage protection circuit TEKADE FELTEN & GUILLEAUME FERNMELDEANLAGEN GmbH 15 April 1975 [10 May 1974] 15393/75 Headings H2H and H2K A circuit for limiting the output voltage of a supply U 1 , designed to provide constant current to a load 9, in the event of a fault in the load circuit, comprises a first resistor 5 in series with a first thyristor 6 across the supply U 1  and a second resistor 2 and thyristor 3 also in series across the supply, a capacitor 4 being connected therebetween as shown, and means 7.1-7.7 for firing the first thyristor 6 when the output voltage U 1  exceeds a limit value, and further means 10.1-10.5 for triggering the second thyristor when the current as sensed by the voltage drop across resistor 8 again reaches a prearranged value when the fault is no longer present. In the embodiment described Zener diode 7.6 conducts when the excess voltage is present and current will then flow through transistor 7.3 to charge capacitor 7.5 and thereby ultimately cause U.J.T. 7.2 to conduct to provide a pulse via transformer 7.1 to fire thyristor 6. A similar F.E.T. circuit fires thyristor 3 when the voltage drop across resistor 8 exceeds a limit value and this causes thyristor 6 to be turned off by the reverse discharge current of capacitor 4, the resistor 2 ensuring thyristor 3 also extinguishes when capacitor 4 is discharged. An optical coupling 11 ensures that the circuit 10 can only function when thyristor 6 is conductive.

Abstract: 960,379. Tunnel diode circuits; pulse signalling. STANDARD TELEPHONES & CABLES Ltd. April 28, 1961 [May 4, 1960], No. 15661/60. Headings H3T and H4L. In a pulse regenerator, a sine wave at the basic repetition frequency of pulse code modulated signals fed to terminals A, B is extracted in a tuned circuit L1, C1 in which losses are reduced by a tunnel diode TD1. A circuit comprising two tunnel diodes TD1, TD2 in series is provided to enable each pulse at terminals A, B to gate a half-cycle of the basic frequency from L1 to serve as a regenerated pulse. The tunnel diodes are preferably biased by direct current fed along the signal line connected to terminals A, B to a potential divider formed by Zener diodes ZD1, ZD2, ZD3. The input pulses are coupled via a tapped inductor L2 to the tunnel diodes TD2, TD3 so that during a pulse at terminals A, B, TD3 exhibits high impedance, hence the greater part of the half-cycle from L1 is passed to the output terminals A<1>, B<1> as a regenerated output pulse. According to the Provisional Specification, the timing signals from L1 C1 may be replaced by locally generated clock pulses.

Title: Improvements in or relating to cathode ray devices
IPC: H01J31/12
Filed: 1948-06-10
Abstract: 653,092. Cathode-ray tubes. WESTERN ELECTRIC CO., Inc. June 10, 1948, No. 15694. Convention date, June 11, 1947. [Class 39 (i)] A cathode-ray tube comprises an evacuated container, an electron gun therein for producing a beam of electrons, a screen or target upon which the beam impinges, and a resonant chamber therein for varying the number of electrons which reach the screen in accordance with signals applied thereto. The television receiver tube 10 shown acts both as a reproducer of signals and as a detector of incoming ultrahigh frequency signal-modulated carrier waves. These are applied directly through a coaxial cable or wave-guide 11 to a resonant chamber 12 within the tube 10. This tube comprises an evacuated container 13 enclosing a cathode 14 focusing control element 15, anodes 16, 17, 18, 19, the resonant chamber 12 between the anodes 16, 17 and two pairs of deflecting plates 20, 21 and 22, 23. A coating 28 forms the final anode. On the end of the tube is a fluorescent screen 24. The anodes 16, 18, 28 and the chamber 12 are all at the same potential, supplied by a source 29. The anodes 17, 19 are connected to intermediate tappings on the source 29. Electrons emitted from the cathode 14 and formed into a beam by the cylinders 15, 16 pass through a gap 32 in the toroidal resonant chamber 12, to which are applied the ultra-high frequency signal-modulated carrier waves. The beam is then directed towards an aperture 33 in the electrode 18 by means of the anodes 17, 18 and has a final acceleration and focussing action by the anodes 19, 28. The electrons passing through the aperture 33 are deflected in coordinate directions by fields of frame and line scanning frequency applied to the deflecting plates 20, 21 and 22, 23. The beam may normally be brought to a sharp focus at the aperture 33 so that a maximum number of electrons pass through the aperture, the beam being defocused by the action of signals applied to the resonant chamber field to decrease the number of electrons passing through the aperture. Alternatively the beam may be normally defocused at the aperture and the focusing increased by the signals so that the number of electrons passing through is increased. One or two additional resonant chambers may be included in the tube for amplification, and are arranged with their apertures in line with the beam. The input to the chamber 12 causes a voltage across the gap 32, varying the velocity of the electrons passing through this gap. In passing from the gap 32 to the gap in the next resonant chamber this velocity variation is converted to a density variation, which produces oscillations in the second resonant chamber and so on, the velocity variation being increased at each stage.
