Title: Improvements in or relating to cyclopropane-(2,3;2,3)-androstane derivatives
IPC: C07J75/00
Filed: 1963-01-03
Abstract: The invention comprises steroids of the formulae <FORM:1029431/C2/1> (wherein R2 is hydrogen or a hydrocarbon carboxylic acyl group of less than 12 carbon atoms which is optionally substituted; and R1 is hydrogen or a C1- 6 alkyl group) and their preparatio by treating an acylate of D 2-androsten-17b -ol or a 17a -alkyl derivative thereof with an alkali metal salt of trichloroacetic acid, an alkali metal salt of monochlorodifluoroacetic acid, phenyl trihalomethyl mercury, a haloform, ethyl trichloroacetate or hexachloroacetone, the haloform being used in the presence of an alkali metal alkoxide, in a solvent inert to the reaction having a boiling point of between 125 DEG  and 160 DEG  C. at reflux temperature, to give the required 17-acylates which may then be saponified to the corresponding 17-ols.  The a - and b -difluorocyclopropane compounds may be separated by chromatographic methods.  The 17-ols may be reacylated by conventional methods. Examples are given.  17a  - Methyl - D 2 - androsten - 17b  - ol acetate is prepared by oxidizing D 2-androsten-17b -ol to give D 2-androsten-17-one, treating this with methyl magnesium bromide to give 17a -methyl-D 2-androsten -17b -ol, and acetylating this.

Title: Improvements in diamond tools
IPC: B24B53/12
Filed: 1941-01-15
Abstract: 543,879. Trueing grinding wheels. MEESON, E. L., and MEESON. J. I. Jan. 15, 1941, No. 565. [Class 60] A diamond tool for trueing a grinding wheel 15 &c. is supported in a reciprocating holder 12 arranged to present it to the work in position to give a trailing cut in both directions of travel and to rock automatically from one position to the other.

The tool may be tipped with a number of diamonds as described in Specification 543,633.
Patent GB-918627-A (GB)
Title: Improvements relating to electric pull switches
Inventor: PICKERING IAN JACK
IPC: H01H17/00
Filed: 1960-01-07
Abstract: 918,627. Cam-operated switches. RAYDEX Ltd. Jan. 9, 1961 [Jan. 7, 1960], No. 566/60. Class 38 (5). A switch actuated by successive pulls on a flexible member 19 comprises a base body part 13 carrying two pairs of fixed contacts 15 (Fig. 2) offset on each side of the section plane of Fig. 1, and a lower body part 16 which carries the moving members of the switch and is riveted to the base 13. A contact actuator 23, formed in one piece and preferably of nylon, has a central part of square section with a cylindrical bearing- part 2311 on each side thereof and a cam 23<SP>111</SP> extending from each end. The cord 19 is attached to a U-shaped leaf-spring 18 reciprocable in a guideway 17 depending from part 16 and housing a coil-spring 22 which urges a loose collar 21 against lugs 20 on member 18. When cord 19 is pulled a pawl 24 carried on one arm of member 18 engages an edge of actuator 23 and rotates it through 90 degrees (Fig. 5, not shown). Return movement under action of spring 22 does not affect the position of actuator 23 and cams 23<SP>111</SP> therefore maintain bridging contacts 25 out of engagement with contacts 15 (Fig. 6, not shown). Another pull on cord 19 rotates actuator 23 a further 90 degrees to restore the parts to a contacts-closed position, as shown in Figs. 1 and 2. Instead of opening and closing two sets of contacts in unison, the actuator 23 may have only one of the cams 23<SP>111</SP> utilized to operate a single bridge 25 (Fig. 10, not shown), or may have the cams 23<SP>111</SP> mutually displaced by 90 degrees so that while one cam permits bridge 25 to engage its associated contacts 15 the other cam holds its bridge 25 out of engagement with the second pair of contacts 15 (Fig. 11, not shown). In a modification (Fig. 12, not shown) the leaf-spring 18 is replaced by a rigid member sliding in guideway 17 and carrying a resilient pawl for engagement with the actuator which is formed with four ratchet teeth in place of the square-section part.
