Title: Improvements in utilization of nuclear energy
IPC: E21B43/24
Filed: 1958-08-25
Abstract: The thermal energy released by the detonation of a nuclear device, is utilized for the recovery of values from an underground deposit of a non-metallic mineral by at least partial conversion thereof to gaseous products of pyrolysis, by preparing a chamber in the deposit at a depth sufficient to contain the force of the explosion and detonating the nuclear device therein.  A roughly spheroidal zone about the detonation chamber is heated sufficiently to produce the gaseous products which collect in fissures and fractures caused by the explosion, the gases being withdrawn through wells drilled down into the fissures and fractures.  The detonation chamber is formed by drilling down into the deposit and filling in above the nuclear device with sand or drill cuttings.  Preferably a number of low power devices are detonated, rather than one or a few high explosive-power devices. A number of detonation chambers are prepared, the detonations being preferably effected at substantial intervals rather than in close succession or simultaneously.  The underground deposit may be carbonaceous, e.g. petroleum, gas shale, bituminous tar sands, and, in the latter case, the bituminous component is converted to flowable liquid hydrocarbons.  If the deposit comprises an inorganic sulphate, e.g. gypsum, the gas produced is mainly sulphur trioxide which may be converted to sulphuric acid by absorption in water at the surface.  If the detonation is in a sulphur deposit or in a bed of pyrites, sulphur vapour is recovered from the wells, whilst carbon dioxide gas is recovered from a detonation in a limestone deposit.

Patent GB-736589-A (GB)
Title: Improvements in the separation of quinaldine from other bases
Inventor: ARNALL PAUL
Filed: 1951-11-20
Abstract: Quinaldine is obtained from a concentrate derived by the fractional distillation of coal tar bases and containing quinaldine and other heterocyclic nitrogenous bases of similar boiling point, viz. boiling within 5 DEG  C. of quinaldine, by a process comprising adding urea or thiourea to the concentrate, separating the resulting precipitate including a quinaldine-urea or -thiourea complex and decomposing the complex to yield quinaldine.  The complex consists of two quinaldine molecules linked to the urea molecule but the reaction is quantitative using excess of the urea.  The complex is preferably formed from aqueous urea in the presence of a solvent for quinaldine that is inert to both urea and quinaldine, such as toluene or other aromatic hydrocarbon, the reacting mixture being heated to above 80 DEG  C. and then cooled to precipitate the complex.  In place of the aromatic solvent, a solvent for urea and quinaldine may be used such as ethanol or the urea may be used in very dilute aqueous solution. The complex may be recovered by filtration and then decomposed by heating with water, preferably in the presence of a solvent for quinaldine which is inert to urea and quinaldine and separable from quinaldine by distillation.  The recovered quinaldine may be further purified by re-crystallization of its complex from ethanol to remove traces of isoquinoline.  An example is given.

Title: Connector crimping assembly
IPC: H01R43/048
Filed: 1963-07-10
Abstract: 968,179. Jointing by stamping. AMP Inc. July 10, 1963 [July 25, 1962], No. 27351/63. Heading B3Q. Apparatus for crimping electrical connectors simultaneously to the ends of two juxtaposed electrical wires arranged in parallel comprises a pair of juxtaposed spaced connector crimping die sets and a wire separating mechanism in which the wires are separated by relative movement between the wires and a wire separating blade, a pair of spring-loaded members arranged to urge the wires against the blade during relative movement between the blade and wires, the members being moved apart during the movement, to locate each wire end in a connector disposed between the dies of one of the die sets. Mounted on a press ram 1 are, a blade 2, a first crimping die 3 having recesses 4, 5 and a second die 6, a shear blade 7 and a pair of spring-biased axially slidable bolts 8 which co-operate with a pair of slides 22, an anvil 16, strip shear plates 13, 14 and a wire support 17, respectively, mounted on a base. The support 17 is spring- biased and mounted on a pair of adjustable bolts 19 slidable in a frame 20 and contains the pair of slides 22 spring-biased towards each other, each slide having an extension 24 protruding through a slot 25 in a wall 26 perpendicular thereto. In operation the bared ends 35 of an insulated electrical twin wire having an insulation separating cut 37 are placed on the extensions 24 and advanced until the ends thereof actuate a microswitch 11 to initiate a press cycle. As the ram descends the leading connectors of strips being fed simultaneously along guide channels 29 lie on the anvil 16 and the blade 2 parts the wires and forces the slides 22 apart, trapping each wire between one side of the blade and one of the walls 26. Further lowering of the ram causes the bolts 8 to depress the support 17 against springs 18 so that the wire ends enter the ferrule portions of the connectors, the bolts 8 move up against their springs 10 and the ferrule portions 31, 32 are crimped about the insulation and bared core of the wires whilst the slug connecting the strip of connectors is sheared therefrom. During the final stroke of the ram the end of the blade 2 is lubricated by entering an oiled felt pad disposed beneath the extensions 24. In a modification the wires are positioned over a blade 2<SP>1</SP> rigidly mounted on a base and a spring-biased carriage 39 lowered so that the surfaces 45 of a pair of spring-biased members 42 pivoted thereon, engage the wires, the members being forced open by the blade to effect separation of the wires which are subsequently trapped between the surfaces 45 and shoulders 47 adjacent to the blade at which point the wire ends are in their crimping position. Continued lowering of the tool holder 9<SP>1</SP> compresses the springs 41 and effects crimping of the ferrules, as before.

Abstract: 966,367. Aircraft controls. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN KOMM. GES.]. July 11, 1963 [July 17, 1962], No. 27495/63. Heading B7G. A mechanical aircraft control system with at least two control inputs 2, 3 acting on a common regulating element 8, e.g. a control surface linkage, has an hydraulic locking device 11 associated with one of the inputs and adapted to allow movement of that input to be transmitted to the regulating element but to prevent movement of the other input or the regulating element from being transmitted to the first input. As shown, the link 8 is connected to an automatic control 3 and through the locking device 11 to a control stick 2. The locking device 11 comprises a cylinder filled with oil and containing a piston 13 having passageways 16, 17 in series, each closed by a non-return valve 18, 19. The piston is fixed to a shaft 23 (Fig. 2), 9 (Fig. 1) and has a recess in which fits a shaft 28 leading to the control stick. The shaft 28 has a bolt 25 mounted at one end, which opens one of the valves 18, 19 when the shaft 28 is moved to allow oil to pass through the passages and allow the piston to move. The shafts 23, 28 are connected together with some end play to allow sufficient relative movement to open the valves. In another embodiment (Fig. 3), the passages 16, 17 in the piston are in parallel so that if the force in the rod 23 exceeds a predetermined value one of the valves is opened to allow the piston and rods to move.

Title: Process for producing chloride dioxide
Inventor: PECHUKAS ALPHONSE
IPC: C01B11/02
Filed: 1956-09-11
Abstract: <PICT:0796778/III/1> Chlorine dioxide is obtained by contacting an aqueous acid solution containing a trivalent chromium compound and a chlorate dissolved therein with a hot inert gas, preferably steam, in amount sufficient to heat the solution with consequent formation of chlorine dioxide, and to strip the chlorine dioxide from the solution.  In the preferred embodiment the reacting solution is contained and prepared in vessel 1, and consists of an alkali metal chlorate and chromic sulphate in an acid aqueous medium, the acid concentration being preferably between 2 and 4 mols./litre. The preferred acid is sulphuric acid.  To prevent reaction it is desirable to prepare and keep this solution below 40 DEG  C.  It is preferred to have between 20 and 120 per cent excess chromic compound present, and particularly 50 to 100 per cent excess. This solution passes downwardly through a gas-liquid contact column 3 in countercurrent to hot steam which enters at 7, heating the solution usually to between 80 DEG  and 100 DEG  C., and stripping out the chlorine dioxide as it is formed.  The vapours pass into scrubber 25 where they are condensed by contact with water to form a solution of chlorine dioxide, which is stored in tank 31.  To avoid explosions it is preferred to use a large excess of steam or other inert gas, for example at least 5 and preferably 9 or more volumes per volume of chlorine dioxide.  The solution passes from the bottom of column 3 into chamber 18, where it is treated with sulphur dioxide to regenerate the chromic sulphate, and is then recycled to vessel 1. Sodium sulphate may be removed by crystallization before the regeneration.  Specifications 581,931 and 796,779 are referred to.
