Title: Apparatus and method of electroslag welding
IPC: B23K25/00
Filed: 1971-10-22
Abstract: 1336348 Welding by fusion AIR PREHEATER CO Inc 22 Oct 1971 [23 Oct 1970] 49281/71 Heading B3R A method of determining the adequacy of flux present in a slag to produce a good weld during an electroslag welding operation involves connecting an A.C. voltmeter 52 isolated from D.C. by capacitor 54 between one of a plurality of the metal members 10, 12 to be welded together and a consumable electrode, e.g. wire 26. The voltmeter indicates, it is stated, an alternating potential difference therebetween clue to the presence of alternating current generated by the passage of direct welding current from a source 32 through the slag lying between the electrode and said metal members. Insufficiency of the amount of flux or slag is indicated by a high voltage reading, i.e. above 0À8 volts. Flux is inserted into the gap preferably by being coated on to one or more tubular guides 22 of consumable filler material and additional flux may be inserted manually by pouring down the guide 22 or by an automatic flux adding device which operates in accordance with the reading on the meter. An audible signalling device may alternatively be incorporated. An apparatus for the operation includes a support bracket 20 temporarily welded at 28 to member 12 but electrically isolated therefrom by insulation 25 and which holds the guide 22 and a reel 24 of welding wire. The wire is fed automatically. Water-cooled copper containment shoes 16 and a plate 23 temporarily welded to members 10, 12 contain the molten metal in the gap between the members 10, 12. Temporary holding bars 14 hold the members in position. The guide or guides 22 may be made to oscillate across the gap to provide an even distribution of heat.

Abstract: 507,180. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEALL, 0. E. Dec. 10, 1937, No. 34312. [Class 40 (v)] A carrier modulated by a standard frequency is converted into the same carrier modulated with twice the standard frequency or with the standard frequency and harmonics, by separating out one side-band, reversing its phase, and adding a variable amount of the reversedphase side-band to the original modulated carrier. In the arrangement shown, a crystal P sharply resonant to one side band is connected in series with phase-changing networks A, B to a tapping on a circuit I tuned to an intermediate-frequency carrier. The selected side-band reversed in phase is amplified in a valve V2 and combined with the original modulated carrier amplified in V1, the amplification of one or both of the valves being variable, e.g. by an adjustable self-biassing resistance R2. If the adjustment is such that the net amplitude of the selected side-band in the common output circuit is the same as that of the other, the output carrier will be modulated with twice the standard frequency, but if the amplitude of the selected side-band is zero or is increased, the output carrier will be modulated with odd and even harmonica of the standard frequency. In a modification, Fig. 2 (not shown), the crystal is connected in a bridge circuit variably coupled magnetically to circuit I and also coupled to a circuit, tuned to the selected side-band, connected across the networks A, B. The - invention may be used at stations controlled from a central station which transmits a carrier frequency modulated by a master frequency.
