Patents by Inventor Hugo Spalinger

Hugo Spalinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Device for rounding off granular particles of solid material
    Patent number: 4592707
    Abstract: Granular solid particles, in particular hard, comminuted material of any given shape, are kept continuously in relative movement in a funnel-shaped container by means of a stream of liquid whereby they are rounded off. The rounded-off particles are suitable as filler material for wear-resistant coatings.
    Type: Grant
    Filed: April 12, 1984
    Date of Patent: June 3, 1986
    Assignee: Swiss Aluminium Ltd.
    Inventors: Werner Borer, Janos Lukacs, Hugo Spalinger

  • Process for melting material
    Patent number: 4220843
    Abstract: A high temperature reactor is fitted with a plasma gun at an anode chamber and is provided with a graphite cathode. The reactor is cooled by means of pipes in the refractory lining of the reactor, and rests on essentially horizontal bearings. The charge to be melted e.g. oxides or oxide mixtures is fed from above at an angle .alpha. at most 90.degree. to the main axis of the reactor in the direction of the plasma stream, and the molten product is tapped off at an exit port which is also close to the entry port of the plasma stream so that the plasma stream covers and therefore heats the area around the exit port.
