Title: Improvements in or relating to Substituted Piperidinoalkylthianaphthenes and Benzofurans
IPC: C07D333/60
Filed: 1968-02-15
Abstract: 1,176,091. Substituted piperidinoalkylthianaphthenes &c. SMITH KLINE & FRENCH LABORATORIES. 15 Feb., 1968 [6 March, 1967; 22 Sept., 1967], No. 7566/68. Heading C2C. Novel compounds having the general formula (I) or a pharmaceutically acceptable acid addition salt thereof, wherein R is at the 5- or 6-position and is H, Cl, Br, F, CF 3 , alkyl of 1 to 4 carbon atoms, or alkoxy of 1 to 4 carbon atoms; R<SP>1</SP> is H, Cl, Br, methyl, CF 3 , F, or methoxy; R<SP>2</SP> is H or methyl; R<SP>3</SP> is H or alkanoyl of up to 6 carbon atoms; Y is oxygen, sulphur, or sulphone; and n is an integer from 2 to 4, are prepared, when n is 3, by condensing a 2 (or 3)- R<SP>2</SP>-3 (or 2)-halomethyithianaphthene or benzofuran substituted at the 5- or 6-position by R, as defined above, with diethyl malonate in the presence of a base to give a substituted malonic ester, hydrolysing this ester with aqueous alkali to give the corresponding malonic acid, decarboxylating this acid by heating to give the corresponding propionic acid, condensing this propionic acid with ethylchloroformate to give the corresponding ester anhydride, and reacting the anhydride with a 1 (or 2)-R<SP>1</SP>-4- phenyl-4-piperidinol to give the intermediate amide having the Formula (II) The intermediates of Formula (II) are described and claimed in Specification 1,176,093, and reducing this amide with lithium aluminium hydride. When n is 2, the same procedure is followed but the acetic acid derivative corresponding to the propionic acid derivative is converted to the acid halide and then condensed with the appropriate 1 (or 2)-R<SP>1</SP>-4- phenyl-4-piperidinol. When n is 4, a similar process is used but the propionic acid intermediate is first homologated by the Arndt- Eistert reaction by conversion to the corresponding propionic acid halide, then condensation with diazomethane and treatment of the resulting diazoketone with the required piperidinol. All compounds of Formula (I) in which R 3  is alkanoyl may also be prepared by acylating the corresponding compounds in which R 3  is hydrogen and in which Y is sulphone by oxidizing the corresponding compounds in which Y is sulphur. 3-Halomethylthianaphthenes are prepared by treating substituted thiophenols with chloroacetone, cyclizing the resulting 1-phenylmercapto-2-propanones and halogenating the resulting 3-methylthianaphthenes. 2-Halomethylthianaphthenes are prepared by reacting thianaphthenes with butyl lithium and formaldehyde and halogenating the resulting 2-hydroxymethylthianaphthenes. 2-Halomethylbenzofurans are prepared by reducing coumarilic acid and halogenating the resulting 2-hydroxymethylbenzofurans. Pharmaceutical compositions containing compounds of the Formula (I) or their pharmaceutically acceptable acid addition salts and having tranquillizing activity (when R<SP>3</SP> is H in Formula (I)) and analgesic activity (when R<SP>3</SP> is alkanoyl in Formula (I)) in association with standard pharmaceutical excipients are administered orally or by injection.

Abstract: 394,085. Gas scrubbers and washers. BRYANT, D. Y., 291, Crow Road, Broomhill, Glasgow, and BLAKELEY, SONS, & CO., Ltd., F., Vulcan Ironworks, Church Fenton, Yorkshire. March 15, 1932, No. 7630. [Class 55 (ii).] Fuel gases are scrubbed in a wash-tower C fed with tarry liquor from a separator G, before proceeding to a superimposed scrubber O packed with tiles, where they are washed with a condensate which is circulated from the separator G through a cooling tank L and a pump N. The scrubbed gases, after progressive cooling in the tower O, may be reheated by returning them through vertical tubes B running the height of the tower and bubble washer, to an outlet T. The height of liquor in the seal may be controlled by means of an adjustable weir plate H in the separator. In a modification the gases pass from the scrubber through a supplemental outlet at the top of the tower, the tubes B then serving as cooling tubes.

Title: Improvements in or relating to radioactive compositions
Inventor: HARVEY BERNARD GEORGE
IPC: C22B60/02
Filed: 1943-05-12
Abstract: Compositions containing uranium X1 are prepared by agitating an aqueous solution containing uranium and radioactive decomposition products thereof with a cation-exchange material in a finely divided condition and separating the cation-exchange material from the solution.  The cation-exchange material may be of the sulphonated coal type or the synthetic resin type, e.g. a hydrogen ion-exchange material known as zeokarb or tannin resin. The uranium X1 may be recovered by incinerating, treating the ash with aqueous acid and precipitating with a water-insoluble polyvalent metal compound, e.g. ferric hydroxide.  The solution of uranium compound may contain ionium, thonium and uranium X1, whereby a composition is produced containing ionium, thorium and uranium X1.  Subsequent treatments of the uranium solution when it has again acquired a uranium X1 content will yield compositions free from ionium and thorium.  The cation-exchange material or a composition prepared therefrom which contains ionium, thorium and uranium X1 may be stored until substantially all the uranium X1 has undergone radioactive decay to uranium II, which is removed by bringing the elements into aqueous solution and precipitating ionium and thorium with ferric hydroxide.

Title: Improvements in or relating to Controlled Speed Motor Arrangements
IPC: H02P5/74
Filed: 1968-02-21
Abstract: 1,198,944. Control of two A.C. motors. SIEMENS A.G. 21 Feb., 1968 [22 Feb., 1967], No. 8337/68. Headings H2A and H2J. An asynchronous motor and a synchronous machine are coupled through gearing so that the machine operates either as a motor or as a generator in accordance with the load on the drive system. The synchronous machine has a nominal mechanical power between 40% and 50% of the maximum output power of the drive system, whilst the asynchronous motor has a power output which corresponds with the difference between the maximum power output and the motor power which can be developed by the synchronous machine. The gearing is arranged to match the speed of the asynchronous motor, at which it produces the desired power to the speed of the synchronous machine. Due to the coupling between the machines, the asynchronous motor is forced to maintain a constant speed and slip, which determines the output power, load fluctuations being absorbed by the synchronous machine.

Title: Post cure method for wire reinforced high pressure rubber hose
IPC: B29D23/00
Filed: 1968-02-22
Abstract: 1,208,320. Reinforced rubber hose. CATERPILLAR TRACTOR CO. 22 Feb., 1968 [27 Feb., 1967], No. 8593/68. Heading F2P. A post cure method for treating highpressure, helically wound, wire reinforced rubber hose, subsequent to the removal of a mandrel associated therewith and an outer wrap on the hose used during vulcanizing comprises heating the hose at a temperature from 200 to 350 F. substantially to remove atomic hydrogen in the wall structure of said hose and age the hose. The method is stated to overcome failure of the reinforcing wires due, it is thought, to hydrogen embrittlement of the wire reinforcement, a realistic curing temperature being suggested as between 250-300 F. for a period of 24 hours, the upper limit of 350 F. obtaining because of the rubber in the hose. Lower curing temperatures require longer curing periods. The outer wrap, which is used during vulcanization and subsequently removed, consists of a nylon shrink tape or, a lead wrap. The Specification suggests that the post cure method drives the chemical reactions, which produce the hydrogen atoms during the vulcanizing process, to completion before the hose is subjected to high pressures and temperatures in use.
