Abstract: 1,147,342. Steroids. UPJOHN CO. 6 April. 1966 [7 April, 1965], No. 15370/66. Heading C2U. Novel compounds of the formula wherein # is a generic expression denoting α- or #-bonds and mixtures thereof; R 1  and R 2  are selected from hydrogen or methyl, Y<SP>1</SP> is selected from the carbonyl radical or a thioketal radical of the formula wherein n is 1 or 2 and R is hydrogen or a (C 1 -C 6 ) alkyl radical; Z is selected from H or (C 1 -C 12 ) acyl radical of an organic carboxylic acid, Q represents H, CH 3 , -C#CA, -CH= CHA, or -CH 2 CH 2 A where A is selected from H, (C 1 -C 12 ) alkyl, chlorine, bromine and CF 3 , are obtained by reducing the corresponding 3-keto #<SP>4</SP> compound to saturate the double bond and if desired reducing the 3-keto product to form a 3-hydroxy compound. The reduction of the α,#-unsaturated ketones may be effected with lithium in ammonia and that of the 3- keto compounds with lithium tri-t-butoxyhydride. 3-Desoxy compounds may be obtained by forming the corresponding 3-thioketal derivatives followed by desulphurization e.g. with sodium metal in liquid ammonia. The compounds may be oxidized e.g. with chromic acid to form 17-keto compounds which after protection of the 3-keto groups if present by the formation of an enamine or ketal, may be treated with the appropriate alkynyl magnesium halide to form a 17α-alkynyl-17#-hydroxy compound. Alternativel an alkyl lithium compound yields the corresponding 17α-alkyl-17#-hydroxy compound. The 17α-alkynyl compounds may be hydrogenated with a Pd catalyst to obtain the corresponding saturated side chain compounds. Pharmaceutical compositions having anabolic, androgenic, sedative, tranquilizing, central nervous depressant, anti-fertility, anti-androgenic and anti-estrogenic activities and containing the above compounds are administed orally or parenterally.

Abstract: 687,638. Automatic liquid concentration control. IMPREGNATION. June 28, 1951 [June 28, 1950], No. 15389/51. Class 38 (iv). [Also in Group XL (b)] The concentration of a liquid, e.g. glue size is controlled by photo-electric detection of changes in the refractive index to operate valves admitting glue or water to the utilization tank. A steam heated glue melting pot 1 supplies glue solution to a thermostatically controlled steam heated storage vat 13 feeds a steam-heated utilization tank 31 through a normally open magnet valve 28 and funnel 25. Overflow from the tank 31 passes into an adjacent tank 38 and is pumped back to the storage vat. The diluting water supply passes through a warming coil 19 in the vat and is controlled by a normally closed magnet valve 22. A photo-electric refractometer 41 (see Group XL (b)) is mounted on the side of the tank 31, to respond to deviations in the concentration of the solution (i.e. its refractive index). Glue is admitted to the tank until the refractive index increases above the preset limit when the refractometer operates to close the glue valve and open the water valve; when the concentration falls below the limit the glue valve opens, and the water valve closes.

Abstract: 959,599. Fuelling reactors. C. A. PARSONS & CO. Ltd., NUCLEAR POWER PLANT CO. Ltd., and A. E. I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. March 20,1962 [May 2, 1961], No. 15888/61. Heading G6C. An arrangement for lowering a string of fuel elements into the channel of a reactor core utilizes a jig which supports the fuel elements at the lower end of the string, the upper end of the jig being connected to the lowering means, the jig being removed after the fuel elements have been inserted in the channel. As shown, the jig comprises a casing 1 having its lower portion formed by four limbs 2, there limbs enclosing the string of fuel elements. The extremities of the limbs have slots 3 for receiving guide vanes 20 on the lowermost fuel element and pawls 5 pivoted at 5a on the limbs 2 extend through slots 20a in the vanes whereby the fuel element load is transmitted to the jig, Fig. 6. Abutments on the limbs prevent counterclockwise rotation of the pawls from the Fig. 6 position. When the lowermost fuel element reaches the bottom of the fuel channel 17 and the jig continues to be lowered the lower edges of the slots 20a in the vanes 20 engage the underside of the pawls and tilt them until they are locked in a free position, Fig. 9, by spring-loaded stops 6 carried by the limbs 2. The jig may then be withdrawn from the channel. To prevent unwanted release of the pawls during lowering of a fuel element string into a channel the uppermost fuel element 19 is located in the recessed end 8a of a rod 8 held in a fixed position by levers 10 pivoted to the jig at 12, these levers being maintained in the Fig. 1 position during lowering of the string by the engagement of rollers 13 on the levers with the inside of a guide tube 14 extending from the reactor charge face 16 to the charge pan above the core 15. When the fuel elements reach the bottom of the channel the rollers 13 leave the bottom end of the tube 14 enabling a spring 9 to raise the rod 8 and thus the limbs 2 may move relatively to the vanes 20 and cause the pawls 5 to move to the Fig. 9 position. Expansion of the fuel element string relatively to the jig is permitted by a member 24 loaded by a spring 23 and having a bridge 24a supporting the lever pivots 12.
