Abstract: The invention comprises 17-cyan-17-ol-estr-4 - en - 3 - one, 3 - ethoxy - 17 - cyan - 17 - ol-estr-3,5-diene, and 3-ethylenedioxy - 17 - cyan-17-ol-estr-5-ene and a process for the preparation of 17-alkyl- and 17-ethynyl-19-nor-testosterones of the general formula <FORM:0838756/IV (b)/1> wherein R represents an alkyl group containing 1 to 4 carbon atoms or an ethynyl group, by converting ester-4-en-3,17-dione into 17-cyano-17 - ol - estr - 4 - en - 3 - one, converting this compound into a 3-ethoxy-17-cyan-17-ol-estr-3,5 - diene or 3 - ethylenedioxy - 17 - cyan - 17 - ol - estr - 5 - ene, and converting the 3-ethoxy or 3-ethylenedioxy derivative into the desired 17-alkyl-or 17-alkynyl-19-nor-testosterone.  The first step may be carried out using acetonecyanhydrin either alone or in alcoholic solution as the reagent to form a mixture of the 17a - and 17b -epimers.  The second step may be carried out using either ethyl ortho-formate in the presence of an alcoholic solution of hydrochloric acid to form the 3-ethoxy derivative, or ethylene glycol to form the 3-ethylenedioxy derivative.  Detailed examples are given.

Title: Improvements in and relating to the production of dehydrating agents for drying gases
IPC: B01D53/26
Filed: 1935-05-30
Abstract: A process for the production of a dehydrating agent for drying gases consists in impregnating carbon with an aqueous solution of calcium chloride.  55 kilograms of charcoal in pieces 5--20 millimetres in size are taken after passing 4 hours in a stove at a temperature 110--120 DEG .  While still hot the charcoal is impregnated preferably in vacuo with an aqeuous solution of calcium chloride having a density of 1,38 and containing 38,6 per cent actual calcium chloride.  After complete impregnation the product is dried by suction or in a centrifugal dryer.  The product is then desiccated in a sheet metal tower supplied with a current of hot air rising from 140 to 170 DEG .  There then remains 100 kilograms of dry product of which 45 per cent is anhydrous calcium chloride.  It is stated to fix 70 to 75 per cent of its weight of water.

Additionally, a safety device is incorporated lest one of the ropes breaks. The device takes the form of two brake bands 116 (normally slack) which are connected to blocks 110, 111 operated by rollers 118, 119. Wheel 102 is mounted in frame 108, 109 pivoted at 500 to cage 36 so that, when one rope brakes, the frame pivots about 500 to cause one of the rollers 118 or 119 to strike a stop 120 or 121, thus applying one of the brakes. This brakes the unwinding of the unbroken rope from wheel 102 to prevent the snapping of this rope as it continues to support the cage.
