Patent GB-678589-A (GB)
Title: Improvements in the synthesis of beta-phenylethyl alcohol
IPC: C07C29/132
Filed: 1950-04-28
Abstract: b -Phenylethylalcohol is prepared by a method which comprises subjecting styrene oxide in liquid phase to the action of hydrogen at room or ambient temperature and moderately super-atmospheric pressure in the presence of a hydrogenation catalyst and a low alkanol which is a solvent for the styrene oxide and resulting b -phenyl ethyl alcohol and thereby effecting conversion of the styrene oxide to b -phenylethyl alcohol.  Hydrogenation catalysts mentioned include nickel, e.g. in the form of Raney nickel, palladium or platinum and compounds of palladium and platinum. Preferably the reaction is carried out in the presence of an alkaline-reacting material which suppresses catalyst poisoning caused for example by thiophenic impurities in the styrene oxide. Preferred alkaline reacting materials include alkali metal hydroxide such as sodium hydroxide though alkali metal carbonates such as sodium carbonate may be used. The reaction may be carried out by a batch or continuous process.  In examples styrene oxide in ethyl alcohol solution in the presence of sodium hydroxide and Raney nickel is treated with hydrogen under pressure at room temperature.  The product is neutralized with hydrochloric acid and extracted with ether and b -phenylethyl alcohol is separated by distillation.  Specification 320,424, [Class 2 (iii)], is referred to.

Filed: 1923-04-20
Abstract: 208,078. F³ber, M. April 20, 1923. Lock mechanism, lever - type. - In a lock having several levers or tumblers, a single spring controls the levers, which are mounted one above the other, the rearmost t one being pivoted to the lever behind it, the spring acting directly on the front lever only. The Figures show three levers, d, d<1>, d<2>, the rearmost one d being pivoted to the casing at b, the next d<1> being pivoted on a pin e carried by the lever d, and the third d<2> being pivoted on a pin f carried by the lever d<1>. The levers are gated to engage a stump on the bolt a in the usual way. The spring g, secured at i to the casing, acts directly on the front lever d<2> only. The increasing distance from the pivot pins of the various levers from the point of application of the spring pressure on the lever d<2> compensates for the decrease in direct pressure by the spring and tends to distribute the pressure of the spring uniformly over all the levers.
