Title: Process for the preparation of keto-steroid compounds
IPC: C07J71/00
Filed: 1952-07-24
Abstract: The invention comprises the 12-cycloethylenemercaptol of 22-isoallospirostan-3b -ol-11-one, and also a process for the preparation of 3-ol-11-keto-steroids which comprises oxidizing 3 : 12-diol-11-keto-steroids with bismuth oxide in the presence of a lower fatty acid to give a mixture of the corresponding 3-ol-11 : 12-diones and the 11-enol derivatives thereof, and thereafter removing the 12-keto group by either (a) treating the mixture with hydrazine hydrate in the presence of an alkali and an ethylene glycol, or (b) treating the mixture with an alkane dithiol, particularly ethane dithiol, to form the corresponding 12-cyclo-alkylene mercaptol derivative and thereafter desulphurizing with Raney nickel.  The process is applicable to compounds of the sapogenin series and to those compounds possessing in the 17-position a hydroxy-alkyl, hydroxy-alkylene, keto-alkyl, keto-alkylene, carboxy-alkyl, carboalkoxy-alkyl, alkyl, alkylene, CH3.CH(OH)-, or CH3-CH(OR)- group (R is an esterifying group).  In examples: (1) methyl 3a  : 12b -dihydroxy-11-keto-cholanate is refluxed with bismuth oxide in acetic acid and the product acetylated with acetic anhydride-pyridine to give methyl 3a  : 11-diacetoxy-12-keto-D 9(11)-cholenate.  Allopregnan-3b  : 12b -diol-11 : 20-dione similarly yields D 9(11) - allopregnen-3b  : 11 - diol - 12 - one diacetate; (2) 22 - isoallospirostan - 3b  : 12b  - diol - 11 - one is oxidized as in (1) to give a mixture of 22-isoallospirostan - 11 : 12 - dione - 3b  - ol and D 9(11) - 22 - isoallospirosten - 3b  : 11 - diol - 12-one, the latter being isolated as its diacetate; (3) the mixture obtained in (2) is refluxed with hydrazine hydrate in ethylene glycol and then heated in the presence of potassium hydroxide to produce 22-isoallospirostan-3b -ol-11-one, together with a little of the corresponding 3b  : 11b -diol; (4) a cooled solution of the mixture obtained in (2) in ethane dithiol is treated with dry HCl gas yielding the 12-cycloethylenemercaptol of 22-isoallospirostan-3b -ol-11 : 12-dione, which on refluxing with Raney nickel in ethanol produces 22-isoallospirostan - 3b  - ol - 11 - one.  Specification 721,953 is referred to.

Patent GB-357261-A (GB)
Title: Improvements in or relating to yarn cutting means for knitting machines
IPC: D04B9/32
Filed: 1930-06-24
Abstract: 357,261. Circular knitting-machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-Assignees of Gagne, A.; Central Falls, Rhode Island, U.S.A.) June 24, 1930, No. 19203. Convention date, July 18, 1929. [Class 74 (ii).] Relates to an auxiliary cutter for cutting splicing yarn at each course during the formation of a high splice. At about 90‹ from the mouthpiece 2 into which the yarns from fingers 3 .. 7 are fed the latch ring bracket carries an extension 10 on which the latch ring is pivoted. On this bracket is attached an arm 12 projecting across the needle circle and split at 13. The split ends encircle a post 15 supporting a binder plate 17 on which are carried the usual pattern controlled cutting and clamping mechanism 18, 19. The pattern lever 22 has connected thereto a link 24 pivoted to the movable cutter 18<1>. A member 25 connected to the link 24 has a downwardly turned end 25<1> which opens the clamp 19 to permit a withdrawn yarn to enter between it and the plate 17. Positioned above the yarn lever 7 and fixed to the shaft 27 is a lever arm 26 with an auxiliary spring plate 261. The shaft 27 has a cranked extension engageable under a pin 33 on the movable cutting element 34 of the auxiliary cutter. The corresponding cutting element 35 extends below the plate 17 to catch the floating yarn. The movement of the lever 7 to feeding position is so timed that the leading short butt needle is the first to knit in the reinforcing yarn. The short butt needles continue to knit in the main and reinforcing yarns until the leading needle reaches a position about opposite the lever 7 at which time the last short butt needle is knitting the reinforcing yarn, which is then taken out of action. As the cylinder continues to rotate the portion of yarn extending from the last short butt needle to the lever 7 first engages a pin 21 and then passes into the clamp 19 which is inactive during the knitting of a high splice. The yarn then passes between the clamp 20 and the upper face of the plate 17 and then beneath the blade 18<1> of the main cutter. Finally it passes between the separated blades of the auxiliary cutter. Subsequently the lever 7 drops into position to feed the next course of yarn to the short butt needles. This movement releases the arm 26 and permits the cutter 34 to sever the portion which would otherwise float. The device can be used in connection with wrap stripe threads carried by a rotating disc 43 as described in Specification 300,605, [Class 74 (ii), Knitting &c.]. By preventing the yarn from forming a float it is prevented from interfering with the floats of the wrap strip yarns and thereby drawing them out unduly. A modification is described. Specification 20101/09, [Class 74 (ii), Knitting &c.], also is referred to.
