Abstract: 1,162,929. Recording and playback. SONY CORP. 19 June, 1968 [19 June, 1967; 22 July, 1967], No. 29245/68. Heading G5R. Signals from a source 3 are fed to two rotary magnetic heads 8a, 8b alternately to record separate tracks on a tape 11 without such an overlap between the tracks as would normally cause the generation of a beat noise during playback. In video recording, the switching circuit 6 for distributing the video signals between the heads is controlled by signals derived from the vertical synchronizing pulses, and control signals are also recorded on the tape by means of a fixed head 23. The switching is effected sufficiently gradually to avoid magnetization of the heads and may be such that one head continues to receive signals at a reduced level while the other head is receiving signals at full strength. The vertical synchronizing pulses control, through a phase comparator circuit 16, the motor 14 driving the rotary record/playback heads 8a, 8b.

[Classes 83 (ii) and 83 (iv).] Making rods; shearing.-In making coated welding electrodes or welding rods bv coating wire with a paste and subsequently cutting into lengths, the freshly coated wire is subjected to a comparatively intense heat so as to harden the surface of the coating to prevent it running and is then cut to length and thoroughly dried. The electrodes &c. may thus be automatically made continuously at high speed from a coil of wire. The wire may be drawn from a drum 1 through a straightener 2 by rollers 3 and then passed through a head 4 on which asbestos or cotton yarn or wire is wound so as to centralize the paste which is applied by an extrusion device 5. The wire then passes through an electric heater 6 to harden the surface of the coating and is received by pairs of gripping jaws on a chain 7. These indent the wire and draw it forwards. The wire is cut into lengths at the indentations by a pair of cutters 8 rotated in synchronism with the gripper and the lengths are deposited on a conveyer 9 which transfers them to a gas-heated drier. The flux mixture may contain silica powder, mineral or synthetic silicates such as felspar, kaolin, iron or magnesium silicates either as yarn or powder, with or without carbonates or oxides of iron, aluminium, manganese, calcium, barium, magnesium, titanium, uranium and zirconium, and/or fluor spar.
