Abstract: 1,014,528. Arc furnaces. UNION CARBIDE CORPORATION. Sept. 17, 1963 [Sept. 24, 1962], No. 36460/63. Heading H5H. In an arc furnace 26 the melt is heated by an arc torch 26 consisting of a metal nozzle 27, having an annular passage 28 through which a coolant is passed, and an axially aligned electrode 30. The tip of the electrode 30 is either above a nozzle passage 31 or flush with or below the passage. The nozzle is insulated by insulators 32, 32 from the electrode and furnace. A gas flows under pressure into the cold-walled nozzle which directs the gas stream into intimate contact with the arc whereby a portion of the gas stream is ionized and directionally stabilized to provide the stable arc path or column to the melt. A pilot arc is first established between the electrode tip and the nozzle 31 by means of a supply through a ballast resistor 35. The main arc is then established between the electrode 30 and a charge material 36. The arc current path is completed through an electrode 38. Stirring of the charge material is effected by the material acting as a current carrying conductor in a field set up electromagnets 39, 40 having windings 41, 42 carrying the arc current. Movement of the material is such as to set up a rolling action in the melt. In an alternative arrangement, the electrode 38 is offset to one side of the furnace and a coil carrying the arc current is arranged annularly with the furnace, the coil axis being vertical, so causing a circulatory stirring action. It is stated that the extent of stirring can be controlled by tilting the axis of the arc torch 26.

Abstract: 1,034,223. Removal of radioactive contaminants from milk. CHEMICAL SEPARATIONS CORPORATION. April 1, 1964 [April 1, 1963], No. 13423/64. Heading A2E. A continuous process for the removal of radioactive contaminants from milk comprises (i) acidifying the milk to reduce its pH to between 5 and 6; (ii) flowing a first portion of the milk into the decontaminating section of a cation-exchange column loop having a shiftable cation exchange resin bed therein, thereby exchanging strontium 90 cations for at least one cation of the class calcium, magnesium, sodium, and potassium; (iii) simultaneously treating a second portion of the resin in a regenerating section of the loop by contacting with a balanced aqueous solution of calcium, magnesium, sodium, and potassium chlorides; (iv) substantially simultaneously interrupting the flow of milk and regenerating solution; (v) shifting the resin bed from one section of the loop to another contiguous section, thereby replacing at least a portion of the resin in the decontaminating section with a portion of resin which has been regenerated, and displacing a portion of the spent resin from the decontaminating section and transferring it to the regenerating section; (vi) re-establishing the milk content of the decontaminating section, whilst maintaining this section free from any other liquid; (vii) simultaneously flowing a second porteion of acidified milk and regenerating salt solution through the decontaminating and regenerating zones; (viii) repeating (iv to (vii) as often as required, and (ix) treating the milk removed from the decontaminating section to restore the original pH of the milk. Step (ix) may be effected in an anion-exchange column, operated in substantially the same fashion as the cation-exchange column described, regeneration being effected by an aqueous alkali solution. This process will at the same time remove iodine-131 from the milk. The acidification of step (i) may be effected by the addition of hydrochloric acid, or alternatively the milk may be passed through an electrolytic cell, wherein basic metallic cations are replaced by hydrogen ions, and step (ix) is effected by flowing the milk through another electrolytic cell, wherein hydrogen ions are discharged and basic metallic cations are reintroduced. The regenerating salt solution may itself be regenerated for recycling, for example by adding an aqueous solution of strontium chloride and calcium sulphate to precipitate the strontium 90 as the sulphate, maintaining the mixture at 80-95C. for about 1 hour, filtering, and restoring the thus-recovered solution to its original composition. Alternatively, the solution may be contacted with a cation-exchange resin having a high affinity for strontium, eluting the strontium from the resin by means of sodium ions, precipitating the strontium by means of sodium carbonate and ferric chloride, filtering to recover a reusable sodium ion solution, and subsequently conditioning the sodium-form cation exchange resin with a solution of calcium, magnesium, sodium, and potassium chlorides for reuse.

During cruise, propulsion is solely by ram-jet engine having one or more combustion chambers 15, Fig. 5, and a nozzle formed by surfaces 31a, 31b, the undersurface 32 of the fuselage, and flaps 30. During take-off and acceleration up to Mach 3, gas turbine engines 14 are used, the secondary ramp being lowered about pivot 65 by jack 66 so that ridge 24 is parallel to ridge 17 to provide an air intake, and surfaces 31a and 31b being lowered and raised by jacks 88, 89 respectively to form an exhaust passage. Flap 30 is pivoted to the fuselage at 78, and the flat member 21 is supported by pivot 30a on flap 30 and by bell crank levers 74 connected to jacks 70. At higher speeds when the gas turbines are shut down, jacks 70 and 95 are operated to raise member 21 approximately parallel to itself to reduce the combustion chamber cross-section, and to lower flap 30 to increase the nozzle exit area and, according to the Provisional Specification, the lifting component of thrust. Supersonic diffusion is obtained during operation of the gas turbine engines by a change in the slope of the ridge 17 at 90. The secondary ramp has two skins 52, 54, the former, in the cruise position, abutting surfaces 16 while the latter defines a gap 44 for removal of the boundary layer (see Division F2). The gas turbine engines may be replaced by ducted fans driven by turbines operating on fuel and oxidant carried by the aircraft. Rocket boosters may assist take-off and acceleration through the transonic range.

Abstract: 1,054,206. Coated sheet material. SOC. RHODIACETA. Nov. 25, 1964 [Dec. 6, 1963; June 26, 1964]. No. 47975/64. Heading B2E. [Also in Divisions B5 and C3]. Microporous coatings are made by depositing on a support a layer of a solution of a water-insoluble linear polyurethane in a volatile solvent miscible with water in all proportions, treating the layer with water at 80 to 100C, for a lengh of time sufficient to coagulate the polymer and thereby cause the layer to become converted into a solid coating, washing the resulting coating with water (preferably at a temperature lower than 80C) to remove residual solvent from the coating, and drying the coating and its supports. The treatment with water is preferably preceded by partial evaporation of the solvent, e.g. for 1 to 5 minutes in air heated to about 70C, and the resultant skin is then treated with water at 80 to 100C. The water may contain a small proportion of a surface-active agent. The substratum on which the layer of the polymer solution is deposited is one to which the coating adheres. In this case it is preferable to use a substratum possessing good permeability to air and water vapour. Woven, knitted and non- woven fabric and paper may be employed as such substrate. The solvent is preferably dimethyl-formamide. The coatings may be employed as substitutes for leather.
Patent GB-1225241-A (GB)
IPC: G03C1/08
Filed: 1967-04-21
Abstract: 1,225,241. Photo-sensitive materials. GEVAERT-AGFA N. V. March 21, 1968 [April 21, 1967], No. 18542/67. Heading G2C. Multi-contrast light sensitive materials comprise a support bearing a layer containing two independently prepared silver halide emulsions which are both spectrally sensitized by the same dye or dye mixture to light in a spectral region (same for both) outside the region in which the emulsions are inherently sensitive, so that the difference in sensitivity of the emulsions to light in the inherently sensitivity region differs from the difference in sensitivity in the sensitized region so that grey wedge prints having different gradations are produced by exposures in the inherently sensitive and sensitized regions respectively followed by development under identical conditions. By exposing the materials to light containing different proportions of light to which the materials are sensitized and inherently sensitive, different contrasts are obtained. The dye(s) may be incorporated (a) in both emulsions during the independent preparations, (b) in a water-permeable layer adjacent the emulsion layer, or (c) in diffusible form in one of the emulsions and allowed to diffuse to the other after mixing.
