Abstract: The invention comprises compounds of the formula <FORM:0739591/IV (b)/1> wherein R is an organic radical derived from a mono-carboxylic acid anhydride R2O, and R1 is an esterified hydroxy group; together with a process for the mono-enolesterification of 11 : 20-diketo-steroids to form the corresponding 20-enol esters of D 17(20) compounds by reacting said diketones with a mono-carboxylic acid anhydride in the presence of perchloric acid and a solvent which has a dielectric constant substantially less than that of the anhydride employed and is unable to act as a "Lewis" base for acylium ions.  Specified solvents are halogenated hydrocarbons, particularly carbon tetrachloride; and the acid anhydrides preferably contain from 4-10 carbon atoms. The reaction is preferably conducted between -20 DEG  and 80 DEG  C., and the products are normally converted without isolation to 17 : 20 epoxide derivatives and thence to 17a -hydroxy-20-keto-steroids. Other methods of enol-esterification are mentioned, dispensing with the particular class of solvent, and using p-toluene sulphonic acid or perchloric acid as catalyst.  In examples (1) 3b -acetoxy-11 : 20-diketo-allopregnane in carbon tetrachloride is treated with a cooled solution of perchloric acid in acetic anhydride, and the mixture, after standing, washed with water, sodium bicarbonate solution, and then the solvent removed, leaving 3b  : 20 - diacetoxy - 11 - keto allo pregn-17 (20)-ene. (2) As in (1), thereafter treating the crude product with monoperphthalic acid in ether and saponifying the resulting epoxide with methanolic potassium hydroxide to yield 3b  : 17a  - dihydroxy - 11 : 20 - diketo - allopregnane.  (3) General details are given for carrying out the process, using as solvents: acetic anhydride, carbon tetrachloride, trichloroethylene, benzene, chloroform, methylene chloride and n-hexane. Specification 739,592 is referred to.

Abstract: 1,015,191. Automatic cop-changing looms. METAPIC S. A. HOLDING LUXEMBOURGEOISE. June 6, 1962 [March 20, 1962], No.21811/62. Heading D1E. A cop of the required colour is released from the magazine by depression of the appropriate rod 18 to rock a cop retainer 15. A connection 33 from the pattern mechanism imparts horizontal movements to a frame 25 carrying a toothed bar 21 so that a tooth lies over the rod 18 corresponding to the weft in the active shuttle; the frame also carries tumblers 43, of which the one corresponding to the active shuttle registers with a striker 82 on the armature 81 of an electro-magnet 78. When the cop feeler detects depletion of an active shuttle, the electro-magnet is operated to tilt the corresponding tumbler to the position shown at 43, thereby storing the need for replenishment of that shuttle. The upper arm of the tumbler is then able (either immediately or when the shuttle again becomes active) to deflect a continuouslyreciprocating striker 76 into line with an abutment 60 on the frame 25, whereby the toothed bar 21 depresses the appropriate rod 18 to release a cop. A fixed abutment 52 returns the tumbler to its normal attitude during descent of the frame 25.

Abstract: 1,159,891. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORP. 15 May, 1967 [12 July, 1966], No. 22363/67. Heading G4H. In a keyboard terminal unit, depression of a key connects together two leads, one from each of two groups of eight leads (Figs. 2A, 2B, not shown), each lead of each group also being connected via diodes (20, 22, Figs. 3A, 3B, not shown) to a corresponding combination of three output leads ("1," " 2 " and " 4 " bits for one group and " 8," " A " and " B " bits for the other) so that as a result of a key depression a corresponding combination of six output leads is marked, and means are provided (Fig. 4, not shown) to inhibit any output if two or more keys are depressed simultaneously. Parity bits for each group of eight leads are also generated, from which a single resultant output (" C " bit) parity bit is produced. Means are also provided (Fig. 6, not shown) whereby a receiving device (e.g. a computer) can issue a busy signal which will inhibit further output from the keyboard until it is ready to receive the next character. Fig. 5 shows the operative coding elements when key W (= "1," " 2 " and " A " bits) is depressed. As a result one H2 of a first group of leads H1-H8 is connected to one V6 of a second group of eight leads V1-V8, to cause current to flow from an "A" bit line which is associated via diodes with the H2 line and from a "2" and a " 4 " bit line which are associated via diodes with the V6 line, to earth via a transistor 70-6. This results in leads " 2," " 4 " and " A " being marked (earthed). Similar circuit techniques are used for parity bits and for the inhibit signal.

Title: Actuating Mechanisms for Control Rods used in Nuclear Reactors.
Inventor: HANSON DOUGLAS OLIVER
IPC: G21C7/14
Filed: 1967-05-16
Abstract: 1,154,687. Controlling reactors. NUCLEAR POWER GROUP Ltd. 9 May, 1968 [16 May, 1967], No. 22671/67. Heading G6C. [Also in Division G3] An actuating mechanism for a nuclear reactor control rod comprises a rotatable member around which passes a flexible member supporting the control rod, electromagnetic clutch means operable when energized to transmit a driving torque to the rotatable member to permit the rod to be raised or lowered, but when de-energized permitting the rod to fall under its own weight, and a mechanical variable inertia device for controlling the acceleration of the rod during its fall. The variable inertia device comprises a casing 21 housing a centrifugal governor 22 comprising a sleeve 22a and arms 22b, the sleeve 22a being mounted for rotation on the shaft connecting the rotatable member to the driving means. A pinion 23 on this shaft meshes with a gear-wheel 24 which drives a step-up gear unit 25 through a free-wheel coupling 26, the gear unit 25 being coupled to a pinion 27 which meshes with gear teeth on the sleeve 22a. Rotation of the shaft when the control rod begins to fall under its own weight drives the sleeve 22a and the arms 22b move outwards due to centrifugal force thus increasing the inertia of the device. The radial movement of the arms 22b is controlled by the vertical position of a sleeve 28 sliding over the sleeve 22a. The drive to sleeve 28 is through a gear-wheel 29 which meshes with the pinion 23, and through a reduction gear 30. The output shaft 31 from reduction gear 30 is threaded and carries a nut 32 to which is coupled a fork 33. This fork 33 is hinged 34 and is moved vertically on rotation of the shaft 31. The two arms of the fork 33 are pinned to the sleeve 28. The reduction gear 30 is chosen so that the shaft 31 makes only a limited number of revolutions (e.g. two) during the whole of the downward travel of the control rod. As the rod falls, the rotation of the shaft 9 produces a vertically downwards movement of the sleeve 28 thus permitting the outward movement of the arms 22b. A suitable contour is provided on the part of the inner face of the sleeve 28 which is in contact with the arms 22b such as to allow for an initial downward travel of the rod before any outward movement of the arms occurs, thus providing constant acceleration initially.
