Title: 1-n-benzyl-beta-methoxy-3-trifluoromethylphenethylamine
IPC: A61K/
Filed: 1971-07-27
Abstract: 1308264 I-N-Benzyl-#-methoxy-3-trifluoromethyl-phenylethylamine SMITH KLINE & FRENCH LABORATORIES 27 July 1971 [28 July 1970] 35156/71 Heading C2C [Also in Division A5] The title compound is prepared by treating the dl form in a lower alkanol with an optically active levorotatory organic acid to form the corresponding optically active salt which is then treated with a base to liberate the l-isomer. Alternatively an aqueous lower alkanol solution of the racemic mixture is treated with an optically active organic acid, (e.g. D-tartaric acid) to remove the d-isomer of the amine then the mother liquor is made basic and subsequently treated with the corresponding enantiomer of the optically active organic acid (e.g. L-tartaric acid) to form a salt from which the l-isomer of the amine is subsequently liberated. The title compound may be. converted into pharmaceutically acceptable acid addition salts such as the hydrochloride.

Abstract: 363,102. Coils for dynamo-electric machines. PUNGA, F., Darmstadt, and ROOS, H., Cannstatt, Stuttgart, both in Germany. Nov. 21, 1930, No. 35167. Convention date, Nov. 22, 1929. [Class 35.] A coil for a rotating field magnet of a dynamoelectric machine is made up of two preformed half coils, the interconnections being made outside the axes of the conductors. As shown in Fig. 5, a strip conductor at the top of a pile a is given two right-angled bends and soldered or welded at c to a similarly bent conductor b which may be the lowest or other conductor in another pile. The ends to be joined may abut or they may overlap. In a modification, Figs. 8 and 9, the two sets of conductors to be joined are spaced apart and the connections c lie at the top in the intermediate space between the two piles. A filling piece d may be employed to make a flat upper surface. If the circumferential space at the end of a core is limited, the coil may be divided into a number of groups with staggered connections as shown in Fig. 10. The conductors in the slots may be bent so as to leave channels for cooling air.

Filed: 1929-12-03
Abstract: 301,756. Hollandsche Maatschappij tot Het Maken van Werken in Gewapend Beton. Dec. 1, 1927, [Convention date]. Sea walls and the like.-Relates to the production of floating caissons and other bodies of concrete for the foundations of quays, waterside embankments and the like. Hitherto a fixed dock 1, Fig. 1, has been connected to the shore by a bridge consisting of two longitudinal bearers 2, over which, and over the walls of the dock 1, travels a crane 3 with a traveller or crab 4 which serves for the transport of the shuttering and the iron for the building of caissons &c. 5 in the dock 1. A traveller 6, 7 on a crane beam 8 conveys the shuttering parts and concrete to similar caissons &c. 9, 10, which are being finished outside the dock. When the structure 9 or 10 is completed it is floated away, and the structure 5, if ready, is floated out of the dock 1, and moored in place of the structure 9 or 10. According to the present invention, the building of the caisson &c. is commenced in a floating dock 16, Fig. 2, parallel with the shore, and as the construction proceeds, the dock 16 is hauled under a bridge consisting of two high lattice girders 11, 12, and carrying a traveller or crab 20, a crane 21, and trucks 22. Below the bridge and guided by piles 14 are unfinished caissons &c. 15, 18, and another, 17, is in the dock 16. When one of the structures 15 or 18 is completed, the unfinished structure 17 is floated out into the place of the structure 15 or 18, and finished there.

Abstract: 427,569. Friction couplings. HALL, C. T., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Dec. 21, 1933, No. 35951. [Class 80 (ii)] A friction coupling comprises a pair of shoes 4 pivotally or slidably mounted on a flange 1 of the driving (or driven) shaft 2 and normally urged by spring means into contact with a driven (or driving) drum 3 so as to provide a slipping drive, control means being provided whereby the shoes can, at will, be moved positively against the drum so as to provide a substantially non-slipping drive. As shown, the free end of each shoe is acted on by one arm of a lever 6 pivoted on the flange 1, the other arm of the lever pivotally carrying a bell-crank lever 8, one arm of which carries a roller 13 engaging a control sleeve 14 slidable on the shaft 2 and having two conical parts 15 and 16 separated by a cylindrical part 17. The other arm of the lever 8 carries an adjustable screen 10, a spring 12 being interposed between the lever 6 and a flange 11 of the screw 10. A spring 24 tends to move the shoes away from the drum 3. The screw 10 is so adjusted that, so long as the roller 13 contacts with the part 15 or 17 of the sleeve 14, the screw 10 does not contact with the lever 6, and the latter is thus controlled by the spring 12. But when the sleeve 14 is moved to bring the roller 13 into contact with the part 16, the screw 10 contacts with the lever 6 and the levers 6 and 8 thus function as a rigid unit. Alternatively, the lever 6 may be actuated directly by the sleeve 14, a spring acting directly on the shoe or on the end of the lever ; or two sets of shoes may be provided, one set being spring loaded and the other set being positively actuated.

An anchorage for an insulatingly sheathed armoured cable laid in a conduit comprises a sleeve cast from hardenable resin around the cable at a region from which the sheath has been removed to expose subjacent armour, and means for fixing the sheath relatively to the mouth of the conduit. As described, the armouring comprises transverse armour tapes 5 and 6 wound around a longitudinal armour tape 4 and covered by a polyethylene or P.V.C. sheath 7. At the region where the sleeve is to be formed the sheath is removed and the exposed part of one armoured tape 6 is replaced by a wire 10, their ends being either soldered together or each soldered to the subjacent armour 4. The sleeve is preferably formed of ethoxylinic-type resin, hardenable in the cold state to which may be added, if required, suitable fillers or hardening agents. The resin sleeve is cast in a mould and after hardening adheres to the armour and the two ends of the cut sheath. The mould forms a recess on the outer surface of the sleeve which provides a bearing surface for members 12, 13 adapted to be clamped around the sleeve by means of bolt 14 and plates 15, the latter preventing transverse movement of the cable.
