Title: Enolates of 9alpha-halo-11-ketosteroids and products prepared therefrom
Inventor: BARTON D H R
IPC: C07J21/00
Filed: 1970-11-17
Abstract: 1376123 #<SP>11</SP>-Enolates; 12-halosteroids RESEARCH INSTITUTE FOR MEDICINE & CHEMISTRY Inc 15 Nov 1971 [17 Nov 1970] 54671/70 Heading C2U The invention comprises (A) a process for the 11,12-enolization of a 9α-halo-11-oxosteroid having at least one 12-hydrogen atom, by treating it in a polar aprotic medium with a strong base; (B) a solution of a 9α-halosteroid- 11,12-enolate in a polar aprotic solvent; and (C) 9α,12,12-trifluoro-11-oxo and -11-hydroxysteroids.  Thus a 9α-halo-11-oxo-12-unsubstituted steroid is converted by process (A) to a Na, K, Li or Mg enolate (the Li enolate being obtainable either directly with Buhi, or by treating an initially obtained Na enolate with LiCl, or by treating a corresponding enol ester with a lithium base). The enolate may be converted to (i) an enol ester by reaction with an acid derivative, e.g. benzoic anhydride; or (ii) an enol silyl ether by reaction, e.g. with Me 3 SiCl; or (iii) a 9α,12-dihalo-11-oxo steroid by reaction with Cl 2 , Br 2 , ClO 3 F or FOCF 3 . The 9α,12-dihalo-11-oxo steroid may be converted to (i) the corresponding 11-ol by reaction with, e.g. NaBH 4 ; or (ii) an enolate by process (A). The enolate may be acidified to give the 12-epimer of the initial 9α,12-dihalo- 11-oxo steroid, or may be converted by methods analogous to those described above to (i) an enol ester; or (ii) an enol silyl ether; or (iii) a 9α-halo-12,12-difluoro-11-oxo steroid. The latter may be reduced to the corresponding 11-ol and any protecting groups (e.g. 3-ketal, 3-enol ether and 17,20;20,21-bismethylenedioxy) removed.  In the examples the starting materials for the above conversions are protected derivatives of 9α-fluorocortisone and 9α-fluoro-16α-methylprednisone.

Abstract: 1325817 Controlling coke ovens KOPPERS CO Inc 30 Nov 1971 [30 Dec 1970] 55638/71 Heading F4K Apparatus for controlling the operation of a battery of coke ovens comprises a movable reversing plate 37 Fig. 5, a number of members 61, 63, 65, 67, Fig. 6 which are capable of movement with the reversing plate and which are connected to respective air and gas control valves of the coke ovens and means for moving the reversing plate and selected ones of the members 61-67 from a neutral position to a first operative position at start of a heating cycle of the coke ovens and to a second position to cause reversal of the heating cycle. The operative ones of the members 61-67 are selected by a locking plate 35, Figs. 4, 6 which moves transversely of the members 61-67 under the control of an hydraulic ram 33. Flanges 39 embrace the reversing plate 37 so that both plates move sideways together guided on rollers 83. Only the reversing plate moves longitudinally. Both plates have cut-away flanges 41, 43 which according to their transverse position engage or do not engage the shoulders of the members 61-67. When the plates are in theposition of Fig. 6 members 61, 63 and 65 are engaged with the flanges 43 of the reversing plate and therefore move with it. Member 67 is engaged with the flanges 41 of the locking plate and is therefore locked against movement. When the plates are in the position of Fig. 60 member 61 is locked and the others move. The locking plate is provided with an interlock to prevent it moving from one position to the other unless the reversing plate is in the neutral position. The reversing plate is moved by an hydraulic ram 31 having two doubleacting cylinders, one piston rod 109 being connected to a fixed point 111 and the other 99 has a head 101 engaged in a guide 97 on the reversing plate 37. By expanding neither, one or both cylinders the first, neutral and second positions are selected. The members 61-67 have extensions 119, 121, 123, 125, Fig. 1 which are connected by chains and pulleys to actuator rods 165, 167, 169 and 195 at the sides of the battery and 183, 185 and 187 along the front. Gas and air valves are actuated by the rods as shown in Figs. 7 and 8. Rod 165 operates valves 201 and 203 or 202 and 204 by similar mechanism movement of the rod from the position shown causes pin 243 on bracket 241 to turn lever 239 clockwise. Rotation of shaft 211 causes locking wedge slider 225 to move to the left and release the lugs 227 of the valves. Further rotation causes clutch 232 to rotate the other part of shaft 211 and lift the valves. Meanwhile pin 243a slides idly in slot 235a of lever 239a. Movement of rod 165 in the opposite direction opens valves 202 and 204 in the same way. The supply of hydraulic fluid is controlled by timing devices through valves so that the air and gas valves open in a desired regular sequence.

Abstract: 1,253,928. Heart assist pump. UNITED STATES ENERGY COMMISSION. 8 Dec., 1969 [24 Dec., 1968], No. 59769/69. Heading A5R. [Also in Division F1] A heart assist pump for either implanted or external application in series with the heart and aorta, comprises a main body 14, and inlet and outlet tubes 12, 16, preferably constructed from polyurethane, and a pair of flexible walls 28, 32 attached to a piston head 34 dividing the body 14 into two chambers 24, 26 and connected to a controlling means by a rod 36 for synchronising the pump with the heart. A left ventricle pulse forces blood to flow along tube 12 through check valve 38 into chamber 24. The pressure compresses a bellows 78 connected by a fluid line 22 to a second bellows 76, which expands moving rod 82 upwards. Rod 82 is linked by a pin 84 to a rod 86 linked by pins 74 and 56 to rods 72, 36 respectively. The rod 86 lifts rod 72 and spool valve 58, allowing a fluid under pressure to pass from a manifold 73, through ports 64, 68 into the chamber above a control piston 52 mounted on the rod 36. The pressure increases and the control piston 52 is forced downwardly against a biassing spring 54 in a cylinder 48 and so forces the piston 34 and walls 28, 32 down, closing valve 44 and forcing blood from chamber 26 through valve 42. At the end of the left ventricle pulse, the pressure in chamber 24 drops, allowing bellows 78 to expand, which operates the spool valve 58 to allow the fluid in the chamber above the piston 52 to vent through ports 68, 66 to return the pistons 52, 34 to their starting positions. Valve 38 closes and blood is forced from chamber 24 to chamber 26 through the open valve 44.
