Filed: 1946-07-05
Abstract: 7-Halogenocholesteryl halides are obtained by treating cholesteryl chloride or bromide in a suitable solvent with a halogenating agent, e.g. N-bromosuccimide, N-bromophthalimide, unsubstituted N-chloro- or bromo-amides of fatty acids having not more than 6 carbon atoms in the molecule, N-chloro- or bromo-acetanilides, having on the para position and, if desired, on either or both of the ortho positions of the benzene ring, groupings such as will prevent the migration of the N-halogen into the para and/or ortho position, these substituents being of such a nature as to be inert to the reagents or products in the reaction mixture, substances having the formula R.CO.NH.X, where X is chlorine or bromine and R is phenyl or substituted phenyl, excluding such substituents as would react under the conditions of the reaction either with the halogenating agent or with the halogenated steroid.  Suitable solvents are those which under reaction conditions are inert both to the reaction components and products, e.g. petrol b.p. about 80 DEG  C.  Preferably, the reaction is brought about by heating to the b.p. of the solvent.  The 7-halogencholesteryl halide may with or without isolation be dehydrohalogenated by methods described in Specification 574,432. Detailed examples are given of methods using N-bromosuccinimide as a halogenating agent.

Abstract: 1,255,228. Building motions. SANT' ANDREA NOVARA OFFICINE MECCANICHEE FONDERIE S.p.A. 22 April, 1969, No. 20598/69. Heading DID. The ring rail in textile machines is vertically displaced by rotations in opposite directions of a drive shaft 1 which is controlled by two microswitches 14, 15 carried on a crank arm attached to the drive shaft. The microswitches are spaced apart in the axial direction of the shaft and are electrically connected to an electromagnetically controlled valve 10 which controls the supply of pressure fluid to a double-acting fluid pressure device 4 arranged to rotate the shaft in opposite directions. The microswitches 14, 15 are actuated by cams which are simultaneously angularly displaceable about the axis of the drive shaft 1 in the path of the microswitches 14, 15. As shown, the cams are mounted on discs 18, 19 which are rotated about the drive shaft 1 by a step-by-step motor 19 in accordance with a programme set in control unit 23. The discs can be rotated by a synchronous motor which is operated at equal time intervals and which rotates only for a preset number of revolutions. This preset number is counted by a perforated disc which is driven by the motor and which cooperates with a transducer connected to the counter, (Fig. 3). The above arrangements provide the ring rail with a stroke of varying magnitude. If it is required to keep the stroke magnitude constant, but to move the mean point of the stroke, the cams 14, 15 can be mounted on a single disc (Fig. 2).

[Class 7 (v)] In an engine starter comprising a starter clutch-jaw member 16, a motor 36 having a shaft 38 for rotating the member 16 and a reduction gear train for transmitting the rotation of the shaft to the member 16 at a reduced speed, a rotative gear member 32 meshes with a gear 28 at the higher speed end of the train and is rotatable by driving-element receiving means 52 when the motor is de-energized and disconhected therefrom when the motor is energized, the means 52 being located at a position spaced from member 16 and operatively connected with the gear member 32 through a flexible shaft 54. A rotatable barrel 2, supports planet gears 26 operating between a stationary orbitalgear 24 and a sun gear 30, the latter being fixed to the internal gear 28 the teeth of which are engaged by a pinion 34 that is part of gear 32. The gear 32 is in mesh with another pinion 40 on the shaft 38 which shaft has attached thereto a flywheel 42. The barrel 20 is connected by a multi-plate, friction clutch 22 to an axially-stationary nut 12 threaded to a screwshaft 14 to which is splined the jaw-member 16, whilst a spring 18 is interposed between the shaft 14 and the jaw-member 16, the spring surrounding the front end of a mesh rod 122 and a shoulder on the rod being in engagement with the rear of the screwshaft. A hollow pinion 48 is in permanent engagement with the gear 32 and an overrunning free-wheel clutch 50 is located inside the pinion 48, the clutch being connected by the flexible shaft 54 to the receiving means 52. The hollow pinion and clutch 50 could be replaced by a screw-and-nut mechanism such as that described above for operating the jaw-member 16. The element 52 is connected to a step-up gear-train 172 which is either operated manually or by a portable electric motor (not shown). The mesh rod is either moved manually by a ring 178, cable 182 and lever 128 or by a solenoid (not shown), whilst another ring 186 and cable 188 is used to lift the motor brushes 102 when the alternative drive through clutch 50 is to be used. A ball 126 is provided on the cable 188 to lock the brushes in the lifted position. When the motor 36 is operated and the flywheel 42 is brought up to speed, the ring 178 is pulled to move the mesh rod 122 axially until the shoulder of the latter pushes against the screwshaft 14 and causes it to turn in the nut 12 and so through the spring 18 to move the member 16 into engagement with the engine jaw-clutch 46 whereupon the shoulders 116 and 118 on the shaft and nut respectively abut so that member 16 is rotated and cranks the engine. To effect starting independently of the motor 36 the ring 186 is pulled to lift the brushes, and the gear train 172 is operated to rotate the flywheel through clutch 50. Oil seals 130 and 126' are provided, respectively, at the rear of the screwshaft and the member 16 whilst the latter has a seal 112 around its periphery.
