Title: Method of preparation of uranium chloride and fusible electrolytes containing the same
IPC: C01G43/08
Filed: 1956-08-24
Abstract: Uranium chloride free from oxygen is produced by introducing into a fused salt bath consisting of one or more of the alkali metal and alkaline earth metal (including magnesium) chlorides, uranium oxide or uranium compounds such as the nitrate, carbonate oxalate, acetate, or other organic salts, which at the temperature of the bath will decompose to give the oxide, and then treating the fused mass with a chlorinating agent, which is preferably gaseous, such as hydrogen chloride, phosgene, carbon tetrachloride, or chlorine in admixture with either carbon monoxide or carbon.  The uranium chloride may either be extracted from the melt by conventional techniques, or the melt may be used for the production of uranium by electrolysis.  In examples, a eutectic mixture of sodium and potassium chlorides was melted at 700 DEG  C. and hydrogen chloride bubbled through the melt. Uranyl nitrate, which may be partially decomposed by prior heating, was added to the melt in small portions, the hydrogen chloride passing through the melt continuously.  Alternatively, the sodium and potassium chlorides were mixed with about two thirds of the uranyl nitrate and this mixture was then melted and hydrogen chloride passed in.  The remainder of the uranyl nitrate was then added as before.

Abstract: 796,792. Coating with metals. BRENNAN, J. B. Sept. 13, 1955 [Dec. 20, 1954], No. 26168/55. Class 82(2) [Also in Group VIII] A method of making a porous strip is charaterized in that reinforcing metallic particles are fed to a batt of inwoven fibres so that they are spaced among and intermingle with the fibres, and the metallic particles are heated and then cool and coalesce with and band together fibres in the batt, forming a non - continuous reinforcement therefor. There may be added to the reinforced batt a further supply of metallic particles which are heated and then cool and band together and to the fibres whereby the strip is rendered conductive transversely and longitudinally. As shown, a fibrous batt B, which may be of cotton or ceramic fibres (e.g. aluminium oxide) is unwound from roll 1, passes under roll 2 and thence under hopper 4 whence metal powder (e.g. aluminium) 5 is fed by rotary screw 6 so as to fall past heating means 3 where it is melted or at least rendered molten on the particle surfaces. Thence the particles drop gently on to and in between the fibres of the batt B which is supported on travelling belt 7. The heating means may employ flames. The batt then passes between rolls 9 whereby it is bonded to form a coherent strip and thence around roll 10 where one side of the batt is subjected to metal spray field 11; then around rolls 12 and 13 to roll 14 where the other side of the batt is subjected to a further metal spray field 11. The completed strip is then wound up on roll 15. The metal sprayed in the fields 11 may be molten aluminium.

Title: Improvements in or relating to charge forming devices for internal combustion engines
IPC: F02M1/00
Filed: 1928-09-22
Abstract: 297,458. Delco-Remy Corporation, (Assignees of Aseltine, F. E., and Teeter, W. H.). Sept. 22, 1927, [Convention date]. Dashpots. - In charge forming devices for internal-combustion engines additional air is admitted through a valve the opening movement of which is damped by a dashpot the resistance of which decreases as the valve is opened. Air is admitted from an inlet 93, Fig. 4, through an opening 95 the admission being controlled by a suction-actuated valve 96 normally held against its seat 97 by a spring 98. The valve is mounted on a spindle 99, guided in a sleeve 100 supported by a spider 101. The lower wall 103 of the manifold has an opening 104 to facilitate assembly and is closed by a washer 105 secured to a plate 106. An adjustable sleeve 107 has a grooved flange 108 by which it may be moved to adjust the tension of the loading spring 98 and to prevent the air valve from opening at starting. To provide for enrichment of the mixture during acceleration and to prevent fluttering of the air valve on sudden opening the throttle, the valve movements are retarded by a dashpot. This comprises a cylinder 115, adjustable in a sleeve 116 attached to the frame 21, holes 117. 118 being provided in the cylinder and sleeve walls below the fuel level in chamber 22. Within the cylinder is a piston 119 sliding on a piston rod 120, Fig. 6, secured to the lower end of the air valve spindle 99. The piston roll has a. flange 121 against a rim 126 on which the piston is normally forced by a spring 122 bearing against an adjustable collar 123. The piston and flange have holes 124, 125, a check valve 127 for the latter being provided. A by-pass 129 has its upper end normally covered by the piston. When the throttle is opened on low or intermediate speeds, suction is transmitted to valve 96 and it descends but not with sufficient force to compress the spring 122; the movement at first is therefore slow. As the by-pass 129 is uncovered, however, the fluid resistance is reduced and the valve opens more rapidly. The greater the throttle opening at the time of acceleration, the less will be the retarding action. Under certain running conditions e.g. coasting, when a very sudden increase in depression would occur on reaching a level or an incline, it is not desirable to retard the opening movement. In such a case the vacuum is great enough to compress the spring 122 so that the flange 121 is separated from the piston, permitting escape of liquid through holes 124 and reducing resistance. To provide an additional retardation, the dashpot cylinder may be raised as the throttles are opened by a bifurcated arm 130, Figs. 4, 6 fixed on a rock shaft 131 which is actuated from the throttle shaft, through an adjustable cam and resilient and adjustable linkage, Figs. 5, 9, 10 (not shown).
