Title: A resistance circuit element composed of a tunnel diode and a backward diode
IPC: H01L29/00
Filed: 1961-03-03
Abstract: 979,794. Tunnel diode switching, amplifying and modulated oscillator circuits. SONY CORPORATION. March 3, 1961 [March 4, 1960], No. 7903/61. Headings H3R, H3T and H4L. A negative resistance or non-linear positive resistance device comprises a tunnel diode and a backward diode connected in parallel. Fig. 8 shows a tunnel diode TD connected in parallel with a backward diode BD through a blocking capacitor 4 and biased from voltages E, E<SP>1</SP>. The tunnel diode has the dashed characteristic 1 (Fig. 9), while the backward diode has one of the chain-dotted characteristics 4a to 4d depending on the value of the bias so that the combined characteristic is as shown at 9a to 9d, depending upon the bias. The backward diode may be used in the forward or in backward direction in a region where it does not present negative resistance. Fig. 10a shows an oscillator comprising a tunnel diode connected in parallel with a tuned circuit 11 and 12 and biased by means of a supply 14 connected across a by-pass capacitor 13, the output being obtained from a coil 21. The tunnel diode is connected in parallel with a backward diode BD, the bias on which may be varied by a modulating source 17 so as to vary the amplitude and frequency of oscillation. The modulating source may alternatively be connected in series with the backward diode (Fig. 10B, not shown). If the tuning capacitor 12 is omitted relaxation oscillations are obtained (Fig. 10C, not shown). The circuit may be modified to operate as a frequency changer by connecting an intermediate frequency output circuit in series with the tunnel diode (Fig. 11, not shown). It is also stated that the combination of tunnel diode and backward diode may be used in an amplifier circuit with an automatic gain control voltage applied to the backward diode. Alternatively, if the tunnel diode is biased to a suitable point on its negative resistance region the circuit may be used as an amplifier which symmetrically limits the signal. The combination of tunnel diode and backward diode may also be used in switching circuits, more particularly where two tunnel diodes are used, the backward diodes being added to equalize the characteristic curves of the tunnel diodes.

Title: Arc welding apparatus
IPC: B23K9/09
Filed: 1970-02-19
Abstract: 1,271,481. Welding by fusion. MITSUBISHI DENKI K.K. 19 Feb., 1970 [19 Feb., 1969], No. 8109/70. Heading B3R. [Also in Division H2] Arc-welding apparatus comprises two sources of current the second source being connected in parallel with the first source whenever the welding electrode and the workpiece are shortcircuited and is disconnected therefrom whenever an arc exists between the electrode and workpiece. Prior to the institution of a welding operation a potential difference obtained from a first current source 10 appears between conductors 16, 18. A relay 22 is thus energized opening contacts 22a, 22b; the contacts 22a reducing the current through the relay 22 to a holding value and the contacts 22b preventing energization of a relay 32. Simultaneously a contactor 38 is energized to close contacts 38a so connecting the second current source 20 in parallel with the first current source 10. When the consumable electrode 12 makes contact with the workpiece 14 the potential difference between conductors 16, 18 disappears and relay 22 is de-energized thus closing contacts 22a, 22b. Relay 32 does not become operated however until the current supplied by the two sources 10, 20 has caused the electrode 12 to burn back sufficiently to cause a potential difference across the arc between conductors 16, 18 which is adequate to operate the relay 32, the relay 22 being arranged so that it is inadequately energized at this potential difference thus causing contacts 22b to remain closed. Operation of relay 32 will open contacts 32b so de-energizing contactor 38 and opening contacts 38a thereby disconnecting the second current source 20 from the first source 10. The relays and the contactor may be replaced by thyristors of transistors.

Filed: 1924-04-01
Abstract: 236,274. Jensen, C. A., (International Metal Products Co.). April 1, 1924. Purifying and refining.- In the manufacture of ingot iron by the open-hearth process, the molten iron in the ladle, prior to pouring into the mould, is degasified and deoxidized by adding sufficient deoxidizing agent, such as aluminium, to result, when using a mould of ordinary size, e.g. 18 inches by 20 inches by 72 inches, in an ingot having a top characterized by a rim of substantially 1 to 2¢ inches in thickness surrounding a cup or depression 2-6 inches in depth. An example of such a top is shown in Fig. 1. If the ingot produced is a large one, as for example in a mould 25 inches by 25 inches by 72 inches, the top of the ingot will have a central projection or projections at the base of the depression, the rest of the base of the depression being substantially flat. An example of such an ingot is shown in Fig. 2. The temperature of the moulds should not be above 500‹ F. When the desired amount of deoxidizing agent has been determined by the above process, the proper proportion of deoxidizing agent is then added to subsequent ladle charges from the same heat. Specifications 27201/09 and 236,273 are referred to.

Inventor: MERCER FRANK BRIAN
IPC: B29C48/05
Filed: 1960-03-09
Abstract: 900,914. Extruding netted fabrics. PLASTIC TEXTILE ACCESSORIES Ltd. Feb. 24, 1961 [March 9, 1960], No. 8256/60. Class 87(2). In a method of manufacturing integral plastic netting, comprising the continuous extrusion of plastic materials to form a net, tension applied to the net is increased during the periods of extrusion of the mass strands to form necks in the strands prior to their solidification. Apparatus for manufacturing said netting 1 includes a screw extruder 4 which feeds plastic material to the annular space 5 between die members 6 and 7 which are rotated in opposite directions by drive chains 8 and 9 from the gear box 12 driven by a motor 13 and which die members are provided with an equal number of strand forming grooves so that integral net intersections are formed when the grooves are in registration. The extruded net is hauled over a former 19 and through a setting bath 16 by and between rollers 17 and 18 driven by a motor 27 via a chain 28 and a shaft 29. A reciprocating crank 31 is journalled on the shaft 29 and is coupled to said shaft by a clutch 30 when said crank and shaft have the same rotational direction. The crank 31 is coupled with a connecting rod 32 adjustably connected to a rotary crank 33 driven through agear chain 34-39 by the motor 13. The management and timing are such that cyclic increments of rotational acceleration are imparted by the crank 31 to the rollers 17 and 18 to give an increased tension in the net to produce necking of the unset strands in the zone 21. Alternatively, the apparatus for varying the net tension may be such that (a) the distance between the extrusion point and the haul off rollers 17 and 18 is variable or, (b) the length of the path along which the net travels between the extrusion point and the haul off rollers is variable or (c) supplementary haul off rollers are included, between the extrusion point and the rollers 17 and 18, to operate during the periods of formation of the strands. Specification 836,555 is referred to.
