  • Patent number: 4069695
    Abstract: Disclosed is a bar-tumbler type safety lock, as well as a key and a coding process for said lock. According to a single-key-entry embodiment, this lock comprises a body, a two-piece washer, a latch holder and a barrel having recesses in which notched tumblers can slide and which is maintained rotatingly and removably toward the front of said body by a stud and a stopping finger retained in two annular slots made radially in this body and which can be retracted by the introduction of a special extraction key into the lock; the coding of the lock is obtained by the turning, in the annular washer-assembly groove, of notches made simultaneously in each of the tumblers with the key inserted.
    Type: Grant

  • Patent number: 4035180
    Abstract: The present invention provides a process for the catalytic reduction of aluminum chloride by manganese to form a high aluminum content alloy, separating the catalysis metal from the alloy, and separating the manganese in the alloy to produce essentially pure aluminum. As a preferred embodiment, liquid aluminum chloride is contacted with solid manganese metal in the presence of a Group IIB metal or compound thereof at a relatively low temperature and at a pressure to maintain the reactants in such phases.

  • Patent number: 4035169
    Abstract: A process is disclosed for collecting and purifying aluminum chloride from gases like those produced from the chlorination of bauxite, clay and other aluminous ores. The method comprises first dissolving the aluminum chloride at about atmospheric pressure in a molten salt solvent in which most of the other principal metal chloride vapors, like SiCl.sub.4 and TiCl.sub.4, are substantially insoluble; then vaporizing and separating the AlCl.sub.3 to produce a purified liquid product. This process eliminates the previous use of costly and/or hazardous compressors and scraped-wall condensers and provides for economical recovery of purified liquid aluminum chloride.

  • Patent number: 3938969
    Abstract: A process for purifying aluminum chloride gas such as that produced in the chlorination of bauxite, clay and other aluminous ores is disclosed. The method first selectively dissolves or liquefies AlCl.sub.3 from an anhydrous mixture of gaseous metal chlorides which may also include the chlorides of Si, Ti, Fe and other metals. More specifically, the method of the present invention provides for selectively dissolving AlCl.sub.3 vapor at substantially atmospheric pressure without the use of costly or hazardous compressors, or the scraped-wall condensers formerly required for this purpose. In addition, the present method allows for economical recovery of the liquefied AlCl.sub.3.

  • Patent number: 3935297
    Abstract: A process of carbo-chlorination of AlPO.sub.4 wherein AlPO.sub.4 or AlPO.sub.4 -containing material is introduced into a reactor along with chlorinating agents and a source of carbon. The reactor is heated to approximately 600.degree. to 1200.degree.C and forms aluminum chlorides, phosphorous oxides, phosphorous chlorides, phosphorous oxychlorides and carbon oxides. These reaction products are then separated into three fractions by condensation, the first fraction being P.sub.2 O.sub.5, the second fraction being AlCl.sub.3 and AlCl.sub.3 .POCl.sub.3 and the third fraction being remaining gasses, namely PCl.sub.3, PCl.sub.5, P.sub.2 O.sub.3, CO and CO.sub.2. The second fraction is reacted in a further reactor to give AlCl.sub.3 and P.sub.2 O.sub.3 which are separated by distillation. The phosphorous chlorides from the third fraction are oxidized, along with the P.sub.2 O.sub.3 of the second fraction, to form P.sub.2 O.sub.5.
