Abstract: 1357678 Dehalogenation of halogenated aromatic amines RHONE-PROGIL 16 Nov 1972 [30 Nov 1971] 53026/72 Heading C2C A process for the preparation of aromatic amines containing at least one halogen atom in the meta-position relative to the amine group comprises contacting at least one polyhalogenated aromatic amine containing at least one halogen atom in the meta-position relative to the amine group and a total number of halogen atoms greater than in the desired product, with hydrogen at a temperature of 280-420‹ C. in the presence of a hydrogenation catalyst with a controlled action, i.e. excluding metals of high catalytic activity such as noble metals and reduced nickel, the preferred catalysts being copper or silver salts, such as the chloride, oxide, nitrate, sulphate or chromite. The polyhalogenated aromatic amine used as starting material may be prepared in situ by introducing the corresponding polyhalogenated aromatic nitro compound into the reaction zone. Examples are described using polyhalogenated aniline.

The aromatic stream 121 is distilled under reflux at 139 and 145 to provide benzene, toluene and xylene. According to Fig. 2 (not shown) a stream containing some benzene, toluene and xylene is recycled to the primary extraction. Suitable primary solvents are water free, water soluble, and have higher boiling points than and are non-azeotropie with the hydrocarbon feed; e.g. dipropylene glycol, triethylene glycol, tripropylene glycol, dibutylene glycol, tributylene glycol, the methyl, ethyl, propyl and butyl ethers of ethylene glycol or of diethylene glycol, sulpholane and N-methyl pyrrolidone, and can also contain "antisolvents" such as ethylene glycol, diethylene glycol, propylene glycol and butylene glycol.

Abstract: 1314669 Electrophonic musical instruments MATTEL Inc 24 Nov 1971 [30 Nov 1970] 54545/71 Heading G5J Apparatus for use in generating musical sounds comprises an endless record having a plurality of harmonizing tracks with re-entrant paths and a plurality of tone tracks. The record has fifty seven tracks, the innermost thirty seven being the tone tracks which each produce a constant frequency note upon the corresponding key on the keyboard being depressed. An accompaniment panel arranged adjacent to the keyboard controls the outer twenty harmonizing tracks, the outermost five of which are used to produce special effects such as an introduction or ending measure for a melody or even applause and yelling. The remaining fifteen harmonizing tracks produce sounds which are useful for accompanying a melody produced by the tone tracks. All of these harmonizing tracks are in the same meter, have the same number of clear beats with the same spacing in each measure, have the same relative note patterns and flourishes and are all in the same tempo. Additionally, the harmonizing tracks are synchronized such that on changing from one track to another at the beginning or middle of a musical measure the new track begins at the corresponding beat in the new track. A thin slit of light mounted above the record illuminates separate photo-cells associated with each track, the output from the photo-cells being connected to an amplifier and loud-speaker via switches operated by the keys on the keyboard and accompaniment panel.

Abstract: 1,145,519. Welding by pressure. P. OPPRECHT. 21 Dec., 1966 [22 Dec., 1965], No. 57245/66. Heading B3R. A welding machine having one or more driven electrodes arranged to move work forwards is provided with means for accelerating the work before the work enters the welding station to a velocity corresponding to that of the electrode or electrodes. In an embodiment the machine comprises a fixed lower arm 3 carrying a roller electrode 9 and a pivoted upper arm carrying a roller electrode 7, electrode wires passing over the roller electrodes being driven by rollers 41, 57. Rails 13 on the arm 3 support a carriage 11 having a holder 15 for the work and a belt 17, connected to the frame of the machine and the carriage, normally urges the carriage to its position shown in Fig. 1. An abutment 19 on the carriage engages a buffer 21 on a bar 23 adjustably secured in a tube 25. The tube 25 carries a control member 29 controlling a limit switch 31 and an abutment plate 35 for movement between two stops 33, 36 fixed to the machine frame. A control bar 37 of triangular crosssection is secured to the plate 35 and is arranged between a roller 43 movable vertically by a piston/cylinder device 47, 49 and the roller 41 for driving the lower wire electrode. With the machine in its start position as in Fig. 1, the work (sheets 59, 61) are secured to the carriage 11 spaced from the rollers 7, 9, the plate 35 contacts the stop 36 and the bar 37 is spaced from the wire driving roller 41. The upper arm 5 is lowered to bring the rollers 7, 9 together and when welding pressure is obtained the rollers 41, 57 drive the wires 53, 55. When the welding pressure is reached air is forced through a conduit 51 to raise the roller 43 and thus the bar 37 against the roller 41. The bar 37 and thus the carriage 11 is moved towards the rollers 7, 9 the plate 35 strikes the stop 33 and the carriage continues towards the rollers 7, 9 to advance the work between the wire electrodes and roller electrodes. The welding current may be reduced to 50-80% e.g. 70-75% of normal as the work initially comes between the roller electrodes and as it leaves the electrodes.
