Title: 5,10-methano-dibenzo-a,d-cycloheptene derivatives and a  process for their manufacture
IPC: C07C61/39
Filed: 1971-04-19
Abstract: 1336634 5,10 - Methanodibenzocycloheptane derivatives CIBA-GEIGY AG 19 April 1971 [13 Feb 1970 12 Jan 1971] 21368/71 Heading C2C Novel amines of the Formula (I) R 1 -alk-A, wherein R 1  is a 10,11-dihydro-5,10-methano- 5H - dibenzo - [a,d] - cycloheptenyl - (10) radical, alk is C 1-7  alkylene or alkylidene and A is a free, mono-substituted or disubstituted amino group in which amino group a substituent may be bonded to the alk radical or in which disubstituted amino group the substituents may be bonded together, may be obtained (a) by reducing X in a compound of formula R 1 -X in which X is a radical which can be converted to -alk-A by reduction and which has an oxo group on a carbon atom adjacent to the amino group, or (b) in a compound R 1a -alk-A in which R 1a  is a 9,10-dihydro-9,10-ethano anthryl- (11) radical corresponding to the 10,11-dihydro- 5,10 - methano - 5H - dibenzo - [a,d] - cycloheptenyl-(10) radical R 1 , which in the 11-position has a radical which can be split off to leave a carbonium ion (e.g. a free or reactive esterified hydroxyl group), this radical is split off with rearrangement to R 1  (e.g. by solvolysis) and, if desired, in the resulting compounds, in the 11- position, a hydroxyl, C 1-7  alkoxy or acyloxy radical is replaced by H, or a hydroxyl or acyloxy group is oxidized to the oxo group. Novel starting materials of the Formula IXa: wherein -alk b -CH 2 - is the same as -alk-, may be obtained by amidizing a compound of the formula R 1 -alk b -COOH or a derivative thereof which is functionally modified at the carboxyl group, or by solvolysing a compound of the formula R 1a -alk b -CO-A, where R 1a  is as defined above. The preparation of intermediates is described as follows: 11-oxo-9,10-dihydro-9,10-ethanoanthracene is reacted with γ-dimethylaminopropyl magnesium chloride to give 11-(γ-dimethylaminopropyl) - 11 - hydroxy - 9,10 - dihydro - 9,10 - ethano - anthracene; 10 - carboxy- 11 - hydroxy - 10,11 - dihydro - 5,10 - methano- 5H - dibenzo - [a,d] - cycloheptene is hydrogenated in the presence of palladium/charcoal to yield 5,11 - dihydro - 5,10 - methano - 5H - dibenzo - [a,d] - cyclohextene - 10 - carboxylic acid which is converted to the acid chloride by warming with oxalyl chloride. Pharmaceutical compositions, useful as psychotropic and sedative agents, comprise compounds of Formula I above together with a pharmaceutical carrier in forms suitable for oral administration. The compounds may also be added to animal fodder since they result in better foodstuff utilization and weight increase of the animals. Compounds with a N-(α-alkylaralkyl)-substituted aminoalkyl group in the 10- position are also useful for the treatment of angina pectoris. The amides of Formula IXa are also useful as psychotropic agents and may be similarly formulated into pharmaceutical compositions.

[Class 7 (v)] In an engine starter in which fluid pressure acting on a piston 21 causes engagement and rotation of a driving clutch 15, 11, auxiliary means is provided for causing both meshing and driving operation independently of the fluidactuated piston. As shown, the piston 21 is secured to a sleeve 22 externally splined at 23 to engage a splined sleeve 20, which is secured to the cylinder 17 by a split clamp 47 attaching the cylinder to a casing 10 bolted on the engine crank-case 13. The sleeve 22 is connected to a sleeve 27 carrying the clutch member 15 by helical grooves 28, 29, these grooves and the splines 23 being provided with anti-friction balls. The clutch member 15 is connected to the sleeve 27 by a sleeve 106 and a friction sleeve 107 having an oblique slot engaged by a pin 108 on the sleeve 106 ; the sleeve portion of the member 15 also has ratchet teeth engaged by similar teeth on a spring-pressed clutch element 98 splined on the sleeve 106. Operation independently of the piston 21 is effected by means of a worm shaft 71, driven by hand or power, and a worm wheel 74 forming part of an adjustable multiple-disc clutch 77, which is connected to the sleeve portion of the clutch 15 by ratchet-tooth clutch elements 84, 94.

Title: Improvements relating to the continuous hydrogenation of fatty oils and fatty acids
IPC: C11C3/12
Filed: 1951-09-20
Abstract: <PICT:0723887/III/1> Fatty oils or fatty acids are hydrogenated by causing the material mixed with catalyst to flow along a channel so the upper surface of the stream is continuously exposed, agitating the stream by jets of hydrogen admitted throughout its length and optionally also by mechanized means, and withdrawing excess hydrogen continuously from the whole area of the upper surface of the stream. Suitable apparatus comprises a vessel 8 divided by baffles 10 into compartments 9 constituting a zig-zag course for the liquid flowing from inlet 1 to outlet 7.  Each compartment is fitted with cooling coils 3, an external heating element 4, and an agitator 2 comprising a rotating hollow shaft having a series of jets arranged in line along its length.  Hydrogen is supplied to the interior of the shafts and by its emergence through the rotating line of jets agitates the liquid.  Unabsorbed hydrogen is withdrawn at 6 and recycled.  The hydrogen supply and temperature of each compartment may be separately adjusted and the length of the liquid path may be varied by the provision of outlets at intermediate points.
