Title: Improved manufacture of hormones
IPC: C07J5/00
Filed: 1937-05-26
Abstract: Unsaturated polycyclic alcohols are oxidized by treatment in presence of an alcoholate of aluminium or of magnesium chloride with an aldehyde or a ketone which acts as a hydrogen acceptor. The process is preferably carried out in the presence of an indifferent solvent such as benzene and at a raised temperature of 50-140 DEG  C.  As hydrogen acceptors there may be used ketones and aldehydes of the aliphatic, alicyclic and aromatic series.  The process of the invention may be applied to polycyclic oxyketones such as dehydroandrosterone, as well as to unsaturated oxy-esters such as androstendiol-acetate-17, and to sterol alcohols such as cholesterol. As the alcohol of the alcoholate there are mainly used tertiary alcohols such as trimethy-carbinol, amylene hydrate, and triphenyl carbinol.  The process may be applied either to pure starting materials or to crude concentrates.  In examples: (1) an acetone solution of cholesterol is treated with a solution of tertiary aluminium butylate in benzene, and the mixture refluxed for seven hours, to give substantially pure cholestenone; (2) a benzene solution of dehydroandrosterone is heated under reflux with acetophenone and aluminate of amylene hydrate for 14 hours to give androstendione; (3) an acetone-benzene solution of 17-methyl-D 5.6-androstendiol-3 : 17 is refluxed with tertiary chloro-magnesium butylate for 20 hours; (4) an acetone-toluene solution of the 17-monoacetate of androstendiol-3 : 17 is refluxed with tertiary aluminium butylate for five hours, to give testosterone acetate; (5) a gasoline solution of ergosterol is mixed with an acetone solution of tertiary aluminium butylate and the mixture refluxed for eight hours to give ergostatrienone.

Title: Improvements in magazine pencils
IPC: B43K21/22
Filed: 1926-06-14
Abstract: 253,907. Feldman, E. D. June 14, 1926. Pencil holders. - In a magazine pencil holder having step-by-step adjustment of the lead, a carrier ring 5 is carried by the lower end of the tubular magazine 3 and is formed with a central passage in which the upper end of an unattached lead gripping and guiding member 7 is adapted to reciprocate, and a spring 12, serving to maintain the carrier ring in normal position, is mounted between the carrier ring and an anchoring-member 10 secured in the lower end of the casing. The lead gripper 7 consists of a split tube having a head of preferably polygonal cross-section and the passage through the ring 5 is preferably round in crosssection and tapering. The ring 5 is secured to or is formed integral with the magazine tube which is slidable in the outer casing 1 and is provided with a detachable operating-cap 4. The ring is formed with slots through which pass arms 14 on a plate 13 forming the bottom of the magazine compartment, and the arms 14 are formed with shouldered ends engaging slots in the member 10 to hold the parts 13 14 immovable relatively thereto. The member 10 is secured in the casing by the tip 11. The lower end of the lead gripper is guided in a part 9 of the bore of the member 10. Pressure on the cap 4 causes the tube 3 and ring 5 to slide in the casing 1, the gripper being carried along with the ring 5 until the lower end strikes the bottom of the bore 9. Further movement of the ring 5 releases the split head of the gripper 7 which, owing to its own resilience,. or under the influence of a spring ring secured thereto, releases its grip on the lead. Release of the pressure on the cap 4 allows the return of the parts to their original positions by the spring 12, the gripper being carried along by the ring 5. without engaging the lead, until the head strikes against the plate 13 and is forced into the bore of the ring. In a modification, the plate 13 is so formed as the upper end of a cylindrical member secured to the member 10, the walls being provided with slots in which slide lugs on the ring 5.
