Title: A Process for Extracting Copper from its Ores or Mineral Compounds
Inventor: GATHY JEAN
Filed: 1906-08-18
Granted: 1907-08-01
Abstract: 1 8,5 7 4. Gathy, J. Aug. 21, 1905, [date applied for under Patents Act, 1901]. Cuprous chloride; hydrochloric acid; carbonic oxide; arseniuretted hydrogen; antimoniuretted hydrogen; phosphoretted hydrogen; sulphuretted hydrogen.-In a process for the extraction of copper from its ores or mineral compounds, the metal is obtained in the form of cupric chloride by a known process. The cupric chloride is treated with sulphurous acid in an absorption tower, cuprous chloride being precipitated. The cuprous chloride is washed, dried out of contact with air, and is then mixed with carbonaceous matter and heated to a dull red heat in a furnace into which steam is introduced. The hydrogen thus liberated reduces the chloride and the hydrochloric acid evolved is used in the earlier part of the process for obtaining the chloride. The carbon monoxide evolved may be collected and used for heating or power. The Specification in its original form as published under the Act of 1901 states also that cupric chloride and lead chloride maybe reduced similarly to cuprous chloride, and that small quantities of sulphur, phosphorus, antimony, or arsenic which might be present with the treated chloride, are eliminated by the hydrogen in the form of volatile compounds. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in Inverted Repulsion Electric Motors.
Filed: 1907-08-08
Granted: 1908-04-09
Abstract: 18,045. Felten & Guilleaume - Lahmeyerwerke Akt.-Ges. Aug. 15, 1906 [date applied for under Patents Act, 1901]. Motors, controlling.-The ordinarily shortcircuited stator windings of an inv e r t e d repulsion motor are supplied with a regulable electromotive force in phase with the potential of the mains whereby the power-factor is improved and the motor enabled to work at high overloads without sparking. The field windings g, h are connected to the variable secondary of a transformer t, which produces a current in the windings in quadrature with the potential of the mains. The field produced in the winding g by this current induces in the armature a potential between the brushes b, the arrangement being such that the potential so produced is of the same sign as that supplied directly to the brushes. Further to improve the power-factor and to prevent sparking, a winding c is arranged in the vicinity of the commutation zone, fed by means of a variable transformer u in parallel with the mains. The windings g, h may be combined into a single winding forming an angle with the axis of the brushes. At starting, it is preferable to short-circuit the stator windings g, h, and gradually to take more and more potential from the transformer.
