Abstract: A method for spot electroplating aluminum onto a metallic substrate without submersion or dipping of the metallic substrate in an electroplating bath, the method comprising: (i) spot coating said metallic substrate with an aluminum ion-containing electrolyte contained within a protective structure possessing at least one aperture, and releasing said electrolyte from said at least one aperture onto said metallic substrate to form a coating of said electrolyte thereon, wherein said electrolyte is in contact with an anode; and (ii) applying a voltage potential between the anode and metallic substrate polarized as cathode when the aluminum ion-containing electrolyte is released from said aperture and forms a coating on the metallic substrate, to produce a coating of aluminum on the substrate. Devices, such as brush and ball pen plating devices, for achieving the above-described method are also described.

Abstract: A room temperature electrolyte comprising a fused salt mixture of aluminum trichloride and an alkyl pyridinium chloride wherein the alkyl radical is selected from the group consisting of ethyl, methyl, 1-propyl and 1-butyl radicals.

Abstract: A thermally activated reserve battery operable within a temperature range of about 165.degree. to 250.degree. C and composed of a lithium-aluminum alloy anode, a molybdenum pentachloride cathode and a separating electrolyte composed of sodium tetrachloroaluminate.

Abstract: A method for preparing alkyl pyridinium chlorides by effecting a direct reaction between the corresponding alkyl chloride and pyridine.

Abstract: An electrolytic process for removing aluminum from a solid two-phase matrix of aluminum and trialuminum nickelide filaments by passing an electric current between an inert anode, a cathode composed of the matrix while both are immersed in an aluminum halide containing molten salt electrolyte.
