Title: Improvements in or relating to electric automatic substations
Filed: 1926-06-07
Abstract: 253,144. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). June 6, 1925, [Convention date]. Vapour apparatus, arrangements of.-A rectifier installation for a substation is arranged so that the regulator can only function when the rectifier is ignited, and the rectifier is connected and disconnected when the load exceeds or goes below predetermined values. The direct-current circuit is supplied by several sources, and when the voltage across this circuit falls to a certain value, a relay u closes to operate another relay s which in turn excites the closing coil q of the main three-phase switch a. Thereupon the rectifier c is excited through the transformer b, and as soon as it is ignited, a relay n closes to connect the regulator mechanism h to the alternating current supply. A contact-making ammeter d controls the mechanism h through relays z to keep the load constant. A minimum current relay v functions through a time relay m to excite the opening coil r of the switch a to shut down the installation when the load falls off. A maximum current relay e opens the direct current circuit on the occurrence of an overload, and a device o thereupon makes three attempts to release the relay e. If the overload still persists the apparatus remains disconnected.

Title: Improvements in or relating to the preparation of steroid compounds
Inventor: LONG ALAN GIBSON
IPC: C07J75/00
Filed: 1953-05-21
Abstract: 2:4-Dibromoallocortisone esters are prepared from the corresponding 2:2-dibromo isomers by rearrangement with hydrogen bromide in the presence of an inert solvent, characterized in that the time of treatment with the hydrogen bromide is within the range of from approximately 3 to 180 minutes.  The 2:2-dibromo isomer is preferably formed in situ by the action of 2 molecular proportions of bromine on an allocortisone ester, and rearrangement effected without isolation of an intermediate bromo compound.  Specified solvents are halogenated hydrocarbons and aliphatic carboxylic acids containg from one to four carbon atoms. The reaction is effected in the range -20 DEG  to +50 DEG  C., preferably between 15 DEG  and 35 DEG  C., and hydrogen bromide is normally added to supplement that produced in the initial bromination stage.  In examples: (1) 21-acetoxy-17a -hydroxy - 3:11:20 - triketoallopregnane in acetic acid (or acetic and formic acids) containing hydrogen bromide is treated with bromine at 16 DEG C., when 2:4-dibromo-21-acetoxy-17a -hydroxy-3:11:20-triketoallopregnane is extracted with methylene chloride and purified by precipitation from a boiling mixture of ethyl acetate and cyclohexane.  (2) As in (1) only using different reaction conditions and effecting the bromination in the following solvents: acetic acid-chloroform, chloroform, methylene chloride, methylene chloride-ether, and methylene chloride-ethanol.  (3) 21-acetoxy-2-bromo-17a -hydroxy-3:11:20-triketoallopregnane in acetic acid containing potassium acetate is treated with bromine (one mol.), and the mixture poured into brine, when 21-acetoxy-2:2-dibromo - 17a - hydroxy - 3:11:20 - triketoallopregnane separates.  Subsequent treatment with hydrogen bromide in acetic acid yields the 2:4-dibromo isomer.

Abstract: <PICT:1060429/C3/1> Sliced beef tendons are placed in perforated container 16, the bottom 18 of the container being hinged in two parts about 19 and having catches 22 which hold the two parts in place. The container rests by means of arms 26 and plungers 27 of hydraulic cylinder 32 in tank 10 containing enzyme solution.

Abstract: 334,840. Smith, W. S., Garnett, H. J., and Dean, J. N. May 9, 1929. Insulating coverings for cables and conductors. -An electric cable, stated to have a low electrostatic capacity, is formed by applying to a conductor a layer of thermoplastic insulating material such as guttapercha, balata, rubber or rubber-bitumen mixtures, treated to develop a cellular structure The cellular structure may be developed by the inclusion of air or other gas under pressure in the thermoplastic material followed by the release of the pressure, or by the incorporation of a substance, such as ammonium carbonate or bicarbonate, which is resolved into a gas at moderate temperatures. In order to render the cable waterproof, a covering of commercial guttapercha or rubber may be applied over the cellular insulation. In an example, a cable is formed by spirally winding a tape of rubber on a copper core, a layer of normal guttapercha being then applied. In a further example, a mixture of guttapercha and finely powdered ammonium carbomate. is extruded upon the conductor at a temperature of 70‹ C. The die from which the mixture is extruded is heated to the full decomposition temperature of the ammonium carbonate-about 120‹ C. In order to allow expansion of the thermoplastic material, without decentralization of the conductor, the die is tapered and elongated. A covering of normal guttapercha completes the cable. In cases where a high breakdown resistance in a power cable is required, the core may be insulated with a cellular insulating material of the type in which the cells intercommunicate, the cells being filled with an impregnating compound having a, low dielectric constant, such as flexible bitumen compounds or mixtures of bitumen and wax. When normal rubber and gutta percha are used in the manufacture of the insulation, an undercoating of purified rubber or other material having a low leakance and low waterabsorbing power may be applied to the conductor. Specifications 307,390; 320,370, 322,208, [both in Class 70, Indiarubber &c.]; 329,275 and 331,454 are referred to.

Title: Separation of propylene oxide from water

Abstract: 1,253,943. Propylene oxide. ATLANTIC RICHFIELD CO. 25 March, 1970 [4 April, 1969], No. 14579/70. Heading C2C. Propylene oxide is separated from water by (a) distilling a feed mixture of propylene oxide and water in the presence of a paraffin or cycloparaffin containing 8-12 carbon atoms and removing the major proportion of propylene oxide and paraffins as bottoms and the major proportion of water as overhead. Preferably the paraffin is present in an amount of 5-40 parts by weight per part of propylene oxide. Since the overhead contains some propylene oxide in addition to water the efficiency of the reflux may be enhanced by cooling the overhead to a temperature at which the maximum solubility of water in propylene oxide is exceeded and a separate water phase occurs. This water phase can be decanted and a portion of the enriched propylene oxide stream used as reflux. The amount of water in the reflux can also be reduced by injecting paraffin into the overhead. The bottoms can be subjected to further separation to remove the paraffin from the propylene oxide.
