Title: Improvements in and relating to electric discharge tube systems
IPC: H05B41/24
Filed: 1955-11-16
Abstract: 850,961. Control systems for discharge lamps. WARNER, A. R., and WARD. D. A. Nov. 9, 1956 [Nov. 16, 1955], No. 32782/55. Class 38 (4). An electric discharge tube installation is provided with two sources of power, one being of zero or low frequency, the other of high frequency, the voltage of the zero or low frequency source being -without the assistance of the voltage of the high frequency source-unable to initiate a discharge in the discharge tubes in the installation. A discharge tube installation comprises a number of discharge tubes Ta, Tb ... Tn, these tubes being supplied in parallel from a direct current source A, the voltage of which is insufficient to initiate a discharge in any of the tubes. The discharge in tube Ta is initiated by the application of a high frequency voltage thereto from a source B, the voltage gradually increasing from zero to a maximum, thus the discharge gradually spreads along the tube from one end. When the tube Ta is fully ignited a relay Ra operates to change over contacts Ral so that the high frequency voltage from the source B is applied to the tube Tb. As the voltage rises once more from zero the discharge spreads along the tube Tb as in the first tube, the operation proceeding until all the tubes in the installation are ignited. The return of the high frequency voltage to zero after each tube is ignited is caused by a pulse which is induced in a transformer Trp in the direct current supply at the completion of the discharge in each tube, the pulse being applied to the high frequency source through a noise limiting device C. The on and off times of the tubes are controlled by a device D. The magnitude of the voltage of the D.C. source may be such that it may-or may not-sustain the discharge in the tubes as desired. The D.C. source may be replaced by a low frequency A.C. source. Specification 679,368 is referred to.

POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE, and COMPAGNIE DE CONSTRUCTION MECANIQUE PROCEDES SULZER. 18 July, 1967 [16 Aug., 1966; 16 Oct., 1966], No. 33014/67. Heading C1A. In a 2-stage catalytic process for deuterium exchange between liquid NH 3  and gaseous H 2 , the 2nd stage (which produces NH 3  richest in NH 2 D) is operated at a temperature 10-100‹ C. higher than the 1st stage, both stages being at temperatures such that NH 3  + HD # NH 2 D +H 2 . In Fig. 2, feed N 2 +H 2  gases (G) pass through tower T 1  to NH 3  synthesis S. The liquid NH 3  produced passes through T 1  in countercurrent to the feed gases and is thereby enriched in NH 2 D. It then passes through T 2  for further enrichment, is evaporated at E (the concentrated solution of catalyst being recycled) and product is withdrawn at P. The remaining D-rich NH 3  is cracked at C into N 2  and H 2  which pass through T 2  and join the feed. The catalyst solution is recycled through tower T 3  in isotope exchange with low-D NH 3  coming from S. T 4  is an isotope exchange tower for saturating feed gases with NH 3 . The gases leaving T 2  contain some slightly deuterated NH 3 , which may be condensed out and (a) recycled directly to the liquid NH 3  entering T 2  (Fig. 3, not shown), (b) revaporized and used in T 3  instead of the NH 3  from S. The catalyst solution is then passed through a further tower T 5  in isotope exchange with the low-D NH 3  from S, which is then used in T 4  (Fig. 4, not shown), or (c) used in tower T 4  instead of the NH 3  from S (Fig. 5, not shown). The temperature in T 1  may be - 10‹ to - 70‹ C., e.g. - 30‹ or - 40‹ C., and that in T 2  may be - 40‹ to + 60‹ C., e.g. 0‹ C. The number of plates in T 1  may be 58, 40, or 37 and in T 2 , 16 or 14. The feed gases (G) may come from a hydrocarbon cracking plant or coke oven recovery gases.

Title: Process of hydrogenating esters of diarylketone carboxylic acid
IPC: C07C51/09
Filed: 1961-09-18
Abstract: A dicarboxylic acid of a diaryl methane and/or an ester thereof is produced by melting a solid ester of a diarylketone carboxylic acid in which the keto-group of the ester is directly connected to both aryl groups and one carboxylic ester group is attached to an aromatic ring in each aryl group and subjecting the molten ester to hydrogenation in the presence of a hydrogenation catalyst and hydrogen, the solid ester being heated to a temperature above 235 DEG C. and hydrogenated whilst at this temperature.  The aryl groups in the ketone may be, for example, phenyl, biphenyl, naphthyl, phenanthryl, anthryl, indyl, dihydronaphthyl, or cyclohexylphenyl, and may carry from 0 to 4 radicals selected from C1-16 alkyls, halogens, amino or hydroxyl groups. The two carboxylic groups are preferably arranged symmetrically in their respective aromatic rings. Preferably the temperature is in the range 240 DEG  to 275 DEG  C., the hydrogenation pressure is at least 14 kilograms per square centimetre gauge, and the contact time at least 0.25 hours.  Suitable hydrogenation catalysts are nickel, cobalt and copper chromite, at least 5% by weight of catalyst, based on the ester charge, being used.  If ester only is required as product, the water produced by the hydrogenation is removed from the reaction system as it is formed.  If the water remains in the system, a mixture of the acid and ester is formed. To obtain the acid alone as the final product, sufficient water is added to hydrolyse the ester to acid.  The solid acid may be separated from catalyst by forming a water-soluble alkali salt, filtering and converting back to the acid.  An example describes the hydrogenation of the dimethyl ester of benzophenone-4,41-dicarboxylic acid to diphenylmethane-4,41-dicarboxylic acid with a small proportion of ester.

[Also in Division G3] In a modification of the automatic carding plant according to the invention of the parent Specification, the fibre supply means is provided with a surplus tuft-receiving return shaft from which the returned tufts may be directly returned to the distributing or circulating duct without passing through a nip and a heating apparatus which therefore receives only the tufts initially fed into the system. Fresh tufts are automatically fed according to a demand determined by a measuring device located at the inlet end of the circulating duct and producing an electric control signal whereby the armature voltage of an electric motor (driving devices for supplying fibre to the feeder) is regulated through a magnetic amplifier. In the feeder shown, unused fibre returns to a shaft 20 having a perforated wall 21 escape of air through which to a shaft 23 is regulated, according to the air pressure within shaft 20 as it fills from the bottom with fibre, by pivoted weighted flaps 22. Delivery rollers 24 withdraw the fibre but release it, before it can be seized by the beater 18, to be conducted over a cleaning grid 19 to suction duct 3 and returned to the circuit. Air escaping into shaft 27 is returned through a dust filter 25 to outlet 26 of beater 18 and used as the medium for conveying fibre through the circulating ducts. In a modified feeder, Fig. 4 (not shown) the outlet of the discharge funnel of shaft 20 is adjacent the beater 18, the rollers 24 are omitted, and the fibre-laden air is not filtered before return to the circuit.
