Title: Improvements in circuit interrupting means for a high voltage d-c circuit
IPC: H01H33/666
Filed: 1966-10-17
Abstract: 1,116,699. Arcing preventing in switches; vacuum switches. GENERAL ELECTRIC CO. 17 Oct., 1966 [14 Dec., 1965], No. 46364/66. Heading H1N. A system for interrupting a high voltage D.C. circuit employs a vacuum switch 25, a charged capacitor 35 and means arranged to discharge the capacitor through the vacuum switch during interruption so as to create an artificial current zero, a normally saturated inductor being connected in series and a capacitor 45 in parallel with the vacuum switch 25. The inductor becomes desaturated as the current is reduced and thus inserts an impedance into the circuit so that the rate of current decay just prior to the current zero is reduced; the capacitor 45, which is in series with a damping resistor 46, serves to reduce the rate of voltage recovery after the interruption. The capacitor 35 may be discharged through a second vacuum switch 38 or alternatively through a triggered spark-gap such as that shown in U.S. Specification 3,087,092. The main switch 25 is retained closed by a latch 30 releasable by a solenoid 64 energized by an overload relay 62 or manually, 80.

Title: Steam generation in nuclear reactors
IPC: G21C1/08
Filed: 1962-12-27
Abstract: 1,023,094. Nuclear reactors. ALLMANNA SVENSKA ELEKTRISKA A.B. Dec. 27, 1962 [Dec. 28, 1961], No. 48627/62. Heading G6C. In a boiling water reactor wherein water flows first along the outside of a fuel assembly and is heated up to or almost to its boiling point, and thereafter flows in the opposite direction through the interior of the fuel assembly, the coolant is caused to rotate rapidly, after passing along the outside of the fuel assembly, by means of inclined guiding surfaces, thus producing a pressure drop, and the coolant enters a funnel-shaped surface up which the liquid coolant flows due to the centrifugal force, the pressure drop causing increased boiling in the inclined contact surface between liquid and vapour. In the drawing the fuel 1 is contained between inner and outer tubes 2 and 3, and coolant is supplied from a duct 4 to the space between tube 2 and tube 5 which separate the coolant channel from the moderator 12. At the upper end of the fuel element the coolant is led between inclined guiding surfaces 6 which cause rotation and increased boiling in the liquid part of the coolant which forms a layer on the tapered surface 7; the edge of the surface 7 may be provided with longitudinal grooves to convert the tangential component of velocity into heat. Steam is collected in a tubular member 8 and water is collected in space 13, being guided if necessary by a partition 14, and returned to duct 4. Steam is led down through the interior of the fuel element and is caused to rotate by inclined guiding flanges 9 attached to the tube 3. The rotation causes any liquid present to pass to the inner wall of the fuel element where it is vaporized and increases the density of the vapour next to the heat emitting surface and so improves heat transfer. The steam superheated inside the fuel element passes to a collecting space 10. The guiding flanges 9 may comprise separate short guiding blades, as shown, or continuous helical surfaces attached to the tube 3, or a number of long helical ribs running close together and formed on the tube 3. When a fuel element has to be changed the cover 11 is removed, and a sealing plug (not shown) is applied from below at the opening to the steam space 10 to prevent coolant flowing from duct 4 into the steam space. The sealing plug is preferably provided with an axial duct through which any liquid inside a newly inserted fuel element may be withdrawn.

The antibiotic is prepared by aerobic cultivation of Streptomyces canadiensis or a mutant thereof which produces she said antibiotic, an aqueous nutrient medium containing assimilable sources of carbon, nitrogen and inorganic salts, suitably at pH 6.0 to 7.8 and 23 DEG  to 38 DEG C.  The micro-organism is said to be a new species, and has the culture deposit number NRRL 3155.  The antibiotic may be obtained from the culture medium by filtering at an acid pH below 5, extracting the filter cake with aqueous C1 to C5 aliphatic alcohol, or by passage of the medium at pH 7.0 through a strongly basic anion exchange resin and elution with an electrolyte solution in aqueous alcohol, or by extraction directly at a pH below 4.0 with a water-immiscible lower alcohol, e.g. butanol.  The extract may be purified by reduction of volume in vacuo, followed by cooling and/or addition of a non-solvent for the antibiotic (e.g. ether, acetone, ethanol, esters, chloroform, benzene or hexane), which precipitates it; final purification may be effected by adsorption on highly basic anion exchange resin, elution with electrolyte solution (e.g. chlorides of Na, K, Ca, Mg or NH4) in aqueous alcohol, dialysis, reduction in volume and precipitation with a non-solvent, when the antibiotic is obtained as the corresponding salt, alternatively fractional elution from an alumina column may be used.  8036 R.P. is active against many named gram-positive organisms, and may be used in pharmaceutical compositions per se, or as a non-toxic salt. Pharmaceutical compositions comprise the said antibiotic or the non-toxic salts thereof with an inert carrier or diluent, suitably in parenterally administerable forms, i.e. intramuscular or subcutaneous injections.  Carriers may be aqueous or non-aqueous, or the compositions may be freeze-dried in ampoules for later reconstitution.
