Patent GB-693754-A (GB)
Title: New therapeutic compounds
Filed: 1950-04-06
Abstract: The invention comprises amines of the formula <FORM:0693754/IV (b)/1> where R1 and R2 are methyl or ethyl (same or different), R3 and R4 are methyl or one may be hydrogen, and R5 and R6 are phenyl.  These are made from the corresponding amino-alcohols R1R2N-CHR3-CHR4-CR R6OH by conversion into the chlorides with thionyl chloride at 30-80 DEG  C. and then splitting off hydrogen chloride.  This may happen spontaneously, or if not, the chloride is treated with a tertiary amine, preferably a further mol. of the amino-alcohol.  The chlorides and the alkenes may be isolated in the form of salts. The products were originally believed to be the ethers of the amino-alcohols.  In the examples: (1) b  - dimethylaminobutyronitrile is made from allyl cyanide and dimethylamine and converted into the ethyl ester of the corresponding acid, e.g. by ethanolic hydrogen chloride; the ester is treated with 2 mols. of phenylmagnesium bromide to give 1 : 1-diphenyl-3-dimethylaminobutanol (isolated as hydrochloride); treatment of the latter with thionyl chloride gives 1 : 1-diphenyl-3-dimethylaminobutene-1 directly, purified as hydrochloride; (2) a -methyl-b -dimethylaminopropiophenone is made (as hydrochloride) from propiophenone, dimethylamine hydrochloride and paraformaldehyde, and treated with phenylmagnesium bromide to give 1 : 1-diphenyl-2-methyl-3-dimethylaminopropanol; the hydrochloride of the latter with thionyl chloride forms the salt of 1 : 1 - diphenyl - 2 - methyl - 3 - dimethylaminopropyl chloride; treatment of the latter with a further mol. of the amino-alcohol yields the hydrochloride of 1 : 1-diphenyl-2-methyl-3-dimethylaminopropene-1; (3) as in (2) using pyridine instead of the amino-alcohol in the final step.  The invention does not include compounds when made by the process of Specification 624,117.ALSO:Analgetic compositions comprise a compound of the formula <FORM:0693754/VI/1> where R1 and R2 are methyl or ethyl (same or different), R3 and R4 are methyl or one may be hydrogen, and R5 and R6 are phenyl, together with morphine or a derivative thereof or a synthetic analgetic of the morphine type. Examples of the latter are amidone i.e. dl-6-dimethylamine-4,4-diphenyl-3-heptanone, pethidine i.e. N - methyl-4-phenyl-4-carbethoxy-pi-peridine and ketobemidone i.e. 4-(m-hydroxyphenyl)-1-methyl-4-piperidyl ethyl ketone.

Abstract: 994,204. Control of two A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 5, 1964 [March 7, 1963], No. 9122/63. Heading H2J. A three-phase motor 1, having a wound rotor, and an auxiliary motor 2, having a squirrel cage rotor, are carried on a crab of a gantry crane which also carries a clutch 3 and brake 4. Trolleys 5, 6, 7, movable with the crab engage stationary conductors connected to remote controller 11. The secondary circuit of motor 1 is connected through collector 8, 9, 10 to resistors 12. When the controller is moved to a first notch, the secondary circuit of the motor 1 is not completed. Relay R is actuated to energize the motor 2, release the brake, and engage the clutch. When the controller 11 is moved to a second notch, relay RCR is connected across a portion of resistor 12 for energization by current induced in the secondary circuit of the motor 1 so that the auxiliary motor and clutch are disconnected. Energization of relay AX causes the rotor circuit of the motor 1 to be completed, and, as the controller is moved to further notches, the speed of the main motor is controlled by varying rotor resistance. The auxiliary motor is not started when the controller is returned to the " off " position, the rotor circuit of the main motor being maintained to allow the motor to come to rest, but being interrupted before restarting of the auxiliary motor is possible. Reverse current braking is provided for the main motor by moving the controller through the " off " position. In another arrangement, a capacitor is connected across the clutch-winding, and some relay contacts are arranged at other points in the circuit.

Title: Improvements relating to the washing and cooling of gases containing sulphur dioxide
IPC: C01B17/56
Filed: 1952-04-09
Abstract: Roasting and combustion gases containing sulphur dioxide are washed and cooled in two or more stages by direct cooling with a liquid which is circulated in a separate cycle for each stage, the whole or a part of the cooling liquid from the first stage being subjected to a direct cooling operation by the evaporation of water therefrom and the cooling liquid in subsequent stages being cooled by cooling surfaces.  Evaporation of water from the first stage cooling liquid may be effected exterior to the washing zone under vacuum or by passage therethrough of cold air in a tower or rotating tube, or by trickling the cooling liquid over acid-resistant material stacked in the open air.  In each case the cooled liquid is passed through a settler to remove solid deposits, chiefly arsenic trioxide, before recirculation.  The first stage cooling is effected at as high a temperature as possible to minimize sulphur dioxide losses. According to examples (1) gases containing 10 per cent by volume SO2 are cooled from 400 DEG  to 78 DEG C. in a first stage cooling by means of 45 per cent sulphuric acid entering at 55 DEG C.  A portion of the hot acid is then passed to vacuum vessel where by evaporation of water the temperature is lowered to 35 DEG C.  The cooled acid passes to a settler where arsenic trioxide is removed and then to a mixing vessel where it is mixed with the remainder of the hot acid to adjust the temperature to 55 DEG C. and to form a mixture no longer saturated with arsenic trioxide, which is then recycled.  The gas from the first stage is passed to a second stage where it is cooled to 30 DEG C. by spraying with a recirculated wash liquid from which the heat is removed by cooling surfaces.  (2) In cooling a gas as in Example 1 from 400 DEG  to 70 DEG C., the washing liquid entering at 60 DEG C., leaves at 90 DEG C. and part is cooled to 35 DEG C. by passing air at 20 DEG C. therethrough.  Impurities are removed as before and the cooled liquid mixed with the remainder to re-form a mixture at 60 DEG C. which is recycled.  The second stage cooling is as before.  Specification 742,052 is referred to.
