Title: Process for the manufacture of products containing aluminiumoxide and one or severalsulphides
IPC: C01F7/40
Filed: 1929-11-02
Abstract: A process for the manufacture of a product containing aluminium oxide and one or several sulphides, for instance, of barium, magnesium, or calcium, in addition to aluminium sulphide, by melting materials containing aluminium oxide, such as calcined bauxite, with a reducing agent such as coke and a heavy metal sulphide, is characterized by introducing a considerable part of the heavy metal sulphide in the form of lumps so that it has insufficient time to melt with the aluminium oxide and carbon, but will sink through the charge to the metallic layer, there to react with any metallic aluminium to form aluminium sulphide.  Thus the formation of aluminium carbide is avoided.  As heavy metal sulphide, pyrites or zinc sulphide or both may be employed, preferably briquetted with metallic iron and about 10-20 per cent of a substance normally containing and capable of liberating moisture, such as uncalcined bauxite, clay, aluminium hydrate or sludge from the conversion of the sulphide melt. Specification 232,549, [Class 1 (iii), Oxides &c., Metallic], is referred to.

Title: Editing system for video tape recordings
IPC: H04N5/7826
Filed: 1966-07-26
Abstract: 1,147,402. Video recording. AMPEX CORP. 26 July, 1966 [2 Aug., 1965], No. 33606/66. Heading G5R. In an editing system for video tape recording which can be used with different tape speeds or television standards, the timing intervals between the detection of a frame sync. pulse, the switch on of a video erase head and the subsequent application of a video signal to a recording head is determined by a counter counting pulses generated by a tachometer which provides an indication of the tape-head speed. The tachometer pulses are also applied with control track pulses to a servo system controlling the video head and tape transport speeds. Assuming that new video information has to be inserted between two previously recorded items by re-recording over a portion of the old information, the video erase head 27 has to be energized when it is adjacent the guard band following a track containing a frame sync. pulse and subsequently the video record heads have to be energized with the new information when the tape is positioned to record the first track following the guard band at which erasure was initiated. To commence operation a start pulse is applied to multivibrator 57 which in turn triggers flip-flop 54. The output of the flip-flop and the subsequent played back frame pulse produce an output from flip-flop 58 which opens gate 59 to allow tachometer pulses to enter counter 61. After a first count which is a function of tape speed and the television standard employed a pulse is issued on lead 62 which after undergoing a first selected delay by multivibrator 66 and a second delay by multivibrator 67 triggers flipflop 69 which in turn energises the erase head via switch 44. This energization takes place when the head is opposite a guard band following a track containing a frame sync. pulse. The issue of the pulse on lead 62 additionally resets the counter which now counts the tachometer pulses occurring when the leading edge of the erased portion of the tape moves up to the recording head. This count is again selected as a function of tape speed but is fixed for the various standards. When one less than the selected number is counted an output appears on line 64 to switch the leads from playback to record and when the selected number is counted a pulse on line 63, after delay in multivibrator 76, switches on the supply to the video recording leads.

Abstract: 447,909. Electrolytic etching machines. BRITISH INSULATED CABLES, Ltd., Prescot, Lancashire, S. D. SYNDICATE, Ltd., 31, Earl Street, London, HARTEL, E. G., The Hollies, The Drive, Wembley Park, Middlesex, and BRISLEE, F. J., Wayside, Rupert Road, Huyton, and BLACKBURN, R., Deans House Hotel, Prescot, both in Lancashire. Nov. 24, 1934, No. 33843. [Class 41] The cathode consists of a curved grid or open structure through which electrolyte is propelled to or from the anode, the centre of the cathode lying nearer to the anode than outlying parts ; in this way excessive etching at the edges of the anode is avoided. In the apparatus shown, the plate 3 to be etched rests on rubber-faced ledges on carrier strips 7 extending the width of the tank, these being adjustably mounted on bars 5 to accommodate different sizes of plate. The strips 7 which extend downwards to near the cathode also serve to limit the etching of the edges. Connection to the anode is made by a recessed disc 10 resting on it, the disc having an insulating casing 11. The cathode consists of a perforated cylinder 13 mounted on a shaft 4 and in communication with enlarged perforated insulating drums 21. Electrolyte is drawn into the cathode and discharged from the drums by centrifugal action. Stationary supplementary cathodes may be mounted on either side of the cvlinder 13 for further control of the current distribution. In a modification, the cylindrical cathode is built of metal rings interleaved with rings of insulating material, the metal rings decreasing in diameter from the centre towards the ends ; by this means distance between anode and cathode increases from the centre outwards in two directions at right angles. In this form the drums 21 are dispensed with and the centrifugal flow is outwards through the cathode. In another modification, the cathode consists of a stationary grid of semicircular bars with their convex sides presented to the anode ; the bars are of equal diameter, but are spaced further apart at the ends, the distribution of current density in two directions being thereby controlled. An independent rotating agitator is mounted beneath the cathode. All metal parts in contact with the electrolyte should be of the same metal as that being etched.
