Title: Improvements in and relating to arc welding
IPC: B23K9/007
Filed: 1957-12-12
Abstract: 839,904. Welding by fusion. UNION CARBIDE CORPORATION. Dec. 12, 1957 [Dec. 17, 1956], No. 38592/57. Class 83 (4). [Also in Group XXXV] In a process of gas shielded arc welding in which striking of the welding arc is facilitated by a pilot arc between the welding electrode and an auxiliary electrode, the voltage supplying the pilot arc is approximately the welding voltage and the work is initially electrically neutral, the pilot are being transferred from the auxiliary electrode to the work by connecting the auxiliary electrode to the work prior to connecting the work in the welding circuit. The process is applicable to seam welding or to spot welding superposed sheets, say, stainless steel sheets about 1 mm. thick. A filler strip 32 is held in place on the work 18 by an insulating template 34 having apertures 36 for locating the gas nozzle 24. The gas nozzle which is of metal, e.g. copper, and constitutes the auxiliary electrode has gas exit passages 37, recesses 38 for the filler strip 32 and a stepped inner portion 31 to prevent erosion of the end surface by the pilot arc. The pilot arc is struck between the non-consumable welding electrode 12 and the nozzle 24 and is transferred by the flow of gas e.g. argon to the work 18 when the nozzle 24 is pressed against the work. After a delay to preheat the work switch 22 is closed and the weld effected. When switch 22 is opened the welding arc ceases and the pilot arc post heats the work and separates the strip 32 from the weld plug 40. Removal of the welding head transfers the pilot arc to the nozzle 24. The process may be manual or automatic. Instead of a filler strip, small discs or a sheet of filler metal can be used.

Title: Methods of simultaneous kinematography and television
IPC: H04N5/225
Filed: 1960-11-14
Abstract: 916,416. Kinematography and television lighting. FERNSEH G.m.b.H. Nov. 14, 1960 [Nov. 13, 1959], No. 39062/60. Class 98 (2). [Also in Group XL (b)] In simultaneous kinematographic recording and televising, the general illumination is supplemented by one or more spotlights (for kinematographic purposes) the spectral characteristic of which and /or the television camera is such that the spotlight will not be effective in producing a charge on the television camera target. As shown in Figs. 1 and 2, the light from spotlight SB may be filtered by a filter F 1  (OG1) so that only the longer wavelengths, which will affect the film in cinecamera FK, reach television camera FSK. An additional filter F 2  (BG12) admits only shorter wavelengths of the general illumination from source GB. This second filter may be formed by the window of the television tube. If the photo-cathode is not responsive to the longer wavelengths, the second filter may be dispensed with. Instead of a second filter, a decelerating potential applied between the photo-cathode and the target electrode prevents low-energy electrons, due to light of longer wavelength, from reaching the target. The filter F 1  may be dispensed with if the spotlight has a spectrum of discrete wavebands (e.g. sodium). These may be filtered out of the television camera system by absorption filters or interference filters. Fig. 3 shows a unit combining a cine-camera FK and a television camera FSK using a single objective and a beam splitter T. An attenuating filter E comprises a cell with variablyseparable faces containing a neutral absorbing liquid. A wavelength-selective filter F 2  may be of similar construction but containing coloured liquid.
