Title: Improvements in deferred action electric batteries
IPC: H01M6/38
Filed: 1959-07-28
Abstract: 861,806. Batteries. ELECTRIC STORAGE BATTERY CO. July 28, 1959 [Sept. 12, 1958], No. 25828/59. Class 53. The electrolyte of a deferred-action battery is contained in a collapsible reservoir 17 closed by a frangible diaphragm 19 situated above a manifold 12 leading through openings 13 to the battery cells. The diaphragm is ruptured by a knife 20 when the cells are to be filled. The knife is enclosed in the reservoir and is attached to a rod 25 carrying a piston 24 which when forced downwards causes the knife to rupture the diaphragm and to be withdrawn into a recess 31 in the battery casing. If the battery is not evacuated of air before activation chambers 14, 15 are provided connected to the cells through openings 16 to receive the air displaced by the electrolyte. When the battery is to be activated the piston 24 is forced downwards by gas pressure from an electricallyoperated squib 26, and the reservoir 17 is collapsed by gas pressure from a squib 38. As the diaphragm 19 must be ruptured before the reservoir is collapsed, the squib 26 is fired before the squib 38. In an alternative method of operation the casing 36 and squib 38 are omitted, and the battery cells are stored under vacuum, the reservoir 17 collapsing under atmospheric pressure when the diaphragm 19 is ruptured. The chambers 14, 15 may then be dispensed with.

Filed: 1973-05-31
Abstract: 1412514 Nuclear reactor safety apparatus GROUPEMENT POUR LES ACTIVITIES ATOMIQUES ET AVANCEES 31 May 1973 [2 June 1972] 26130/73 Heading G6C Nuclear reactor safety apparatus comprises a container intended to be disposed in the reactor with its lower part in the core and neutron absorber retained in an upper part above the core, the lower part having an aperture extending to the outside of the container and normally sealed by a closure member, certain reactor conditions causing unsealing of the aperture to result in the neutron absorber moving into the lower part. In one embodiment (Fig. 1) the container 1 is internally partitioned into three compartments 4, 5, 6 and contains a central tube 7 leading to a gas-inlet valve 8 and a sealed opening 9. A conduit 10 penetrates the bottom wall of the container 1 and is sealed by a brazed in uranium plug 11. Gas is supplied to the interior of the container 1 via valve 8 and, by repetitive pressurisation and depressurization boron carbide powder 20 in the lower compartment 4 is raised into the intermediate compartment 5 to lie on the turns of a helical blade 17. Gas is stored in the upper compartment 6 under pressure. In operation, with an increase in neutron flux in the core causing a rise in temperature thereof, the braze melts, plug 11 is expelled causing depressurization of the lower compartment 4 and the powder 20 moves rapidly from the intermediate compartment 5 (above the core) to the lower compartment 4 (in the core). In another embodiment (Fig. 2) a block 23 of sintered boron carbide is retained by frangible elements 25 in the upper part 22 of the container 1 whose lower part mounts a shock-absorber 26. The interior of the container 1 is pressurized by gas injected through valve 29. In the event of expulsion of the closure plug 28, gas pressure above the block 23 causes the elements 25 to break and the block 23 to fall to the lower part 21 (in the core). In a modification (not shown) for use in a gascooled reactor, the bottom aperture is sealed by a frangible diaphragm and the container contains gas at reactor pressure. In the event of loss of reactor pressure, the diaphragm ruptures.

Title: Improvements in or relating to process of polymerizing rosin and the product resulting therefrom
IPC: C09F1/00
Filed: 1939-09-20
Abstract: 536,218. Polymerized rosin.  NEWPORT INDUSTRIES, Inc. Sept. 20, 1939, No. 26219. Convention date, Sept. 28, 1938. [Class 2 (iii)] [Also in Group III] A polymerized and disproportionated rosin is prepared by dissolving rosin in an inert solvent therefor, dehydrating the solution, e.g. by heating under reflux, and then heating the dehydrated solution with anhydrous zinc chloride, anhydrous conditions being maintained. A disproportionated rosin is an admixture of dehydro- and dihydro-rosin acids. By this process, the melting point of the rosin is increased, the acid value is substantially maintained, and yields approaching 100 per cent. are obtainable. Specified rosin solvents are a petroleum hydrocarbon boiling between 105 and 140‹C., benzene and toluene. The amount of zinc chloride used is generally about 1.5 -3 per cent. of the weight of the rosin. The amount of rosin in the solution is preferably 62-70 per cent. by weight of the solution, and the reaction temperature is preferably not above 145‹C. After heating has been completed, nigre may be precipitated by the addition of further solvents and the solution may then be treated with an aqueous solution of an acid, such as formic, acetic, sulphuric or hydrochloric acid, to produce a water-soluble salt of.any zinc present, which salt is then completely removed by washing with water. Solvent may then be removed by steam-distillation, and the rosin product subjected to heating at 250-300‹C. to effect further disproportionation. The resultant product may then, if desired, be fractionally vacuum-distilled, to separate it into a dextrorotary distillate and a laevo-rotary residue.
