Abstract: A cobaltic oxide hydrate is mixed with spent sulfate electrolyte and the slurry is sparged with air to liberate any entrained chloride ions as gaseous chlorine. Thereafter a reducing agent is used to enable dissolution of the cobalt and obtaining of a chloride-free solution from which, after purification, cobalt can be electrowon.

Abstract: The invention is directed to a process for producing metal powder through atomizing in which a molten metal stream is subjected to the influence of a plurality but correlated sets of atomization jets by virtue of which a disintegrating medium exits from the jets at a velocity of at least Mach No. 1, the medium from one set of jets being angled to strike the falling molten body at a point below and at an angle less than the medium dispensed from the other set of jets, whereby less flake and filigree are formed, a higher powder yield obtains, lower medium pressure can be used, etc.

The rim-portion is used to maintain an electrolyte-tight seal in operation.

Abstract: A method and apparatus for detecting predetermined operating conditions of a machine driven by an electric motor, in which a filtered electric signal is utilized. The filter is designed to signal the occurrence of frequencies within a predetermined band, thereby enabling detection of an event characterized by the occurrence of such frequencies. The output of the filter can be used, for example, in a further device to operate an alarm, turn off the motor, reduce the feed to the machine, or any other suitable control action.

Abstract: Nickel forms, such as pellet and shot, are useful as electroplating anode materials; however, due to their small size, it is difficult to retain the nickel forms within conventionally used titanium mesh plating baskets. Nickel forms that have been work flattened are readily retained in conventional anode baskets and provide, in addition, a surprising increase in activity and a desirable coarse residue.

Abstract: The invention relates to an improved silver/silver-chloride reference electrode adapted for use in aqueous corrodent solutions at high temperatures and high pressures. The reference electrode provides a useful standard for measuring electrochemical phenomena related to the corrosion process so that metals can be compared on a thermodynamically useful scale. The formation of bubbles within the reference electrode, which can cause open circuit conditions, is substantially avoided by equalization of internal and external pressure through the use of a heat sealing vent means within the electrode body. Ionic conduction between the electrolyte contained within the reference electrode and the corrodent solution is controlled by a bridge containing tightly gripped fibers which are subjected to additional compression during heating and subsequent pressurization.

Abstract: An article such as a screen printing cylinder prepared from a hard nickel electrodeposit is characterized by improved resistance to embrittlement when exposed to temperatures above about 200.degree. C. Electrodeposits affording improved resistance to embrittlement contain 0.007-1% sulfur and 0.02-5% manganese. The amount of manganese in the electrodeposits is correlated to the amount of sulfur present so that the manganese is present in an amount in excess of the stoichiometric amount required to form manganese sulfide. The electrodeposits which are also characterized by usefully low levels of internal stress are prepared using conventional nickel plating baths modified by the addition of sources of manganese ions and sulfur.

Abstract: A method for coating a metal wire with a thin layer of a second powdered metal. A metal flake powder having a residual surface lubricant from a prior milling operation is placed in the lubricant holding box of a conventional draw bench. The wire to be coated is passed through the metal flake powder and drawn through a conventional drawing die to provide a green-coat wire having a mechanically adherent metal flake powder coating. The green-coat wire is subsequently sintered to metallurgically bond the coating to the wire surface.
