  • Patent number: 5935170
    Abstract: A device for disconnection of a connecting device between an implant (2) and a device (12) connectable thereto, which coupling device is of the type incorporating a first and a second coupling part (6 and 11, resp.
    Type: Grant
    Filed: September 30, 1997
    Date of Patent: August 10, 1999
    Assignee: P & B Research AB
    Inventors: Bo H.ang.kansson, Peder Carlsson
  • Patent number: 5735790
    Abstract: A device for interconnecting an implant (2) anchored in the skull bone of a person with impaired hearing, which acts as or supports a first coupling part (7) and a second coupling part (14) interconnectable therewith and connected to a vibration exciting apparatus, whereby said coupling parts are constituted by a substantially cup-shaped female part (7) and a male part (14), which is insertable therein under mutual flexing, the female part (7) being designed as a rigid cup-shaped seat, whereas the male part (14) is designed to be resilient in radial direction in order to permit a snap-in introduction into the female part (7).
    Type: Grant
    Filed: December 1, 1995
    Date of Patent: April 7, 1998
    Assignee: P & B Research AB
    Inventors: Bo H.ang.kansson, Peder Carlsson
  • Patent number: 5653861
    Abstract: The invention relates to a method of producing pulp comprising a step of forming green liquor containing alkali metal sulfide and alkali metal carbonate. The method further comprises a step of electrochemically treating the green liquor to oxidize at least part of the sulfide therein.
    Type: Grant
    Filed: April 4, 1996
    Date of Patent: August 5, 1997
    Assignee: Eka Nobel AB
    Inventors: Johan Landfors, Bo H.ang.kansson
  • Patent number: 5624545
    Abstract: Sulphide-containing white liquor is treated in a continuously operating electrolytic cell having separate anode and cathode compartments separated by a partially permeable barrier. White liquor is introduced into the anode compartment of the cell, and an aqueous solution of alkali metal hydroxide is introduced into the cathode compartment of the cell so that sulphide is oxidized in the anode compartment, while at the same time alkali metal cations are transported through the barrier into the cathode compartment, where water reacts to form hydroxide ions. An electrolytic cell suited for implementing the method is also disclosed.
    Type: Grant
    Filed: December 18, 1995
    Date of Patent: April 29, 1997
    Assignee: Eka Nobel Inc.
    Inventors: Johan Landfors, Bo H.ang.kansson, Maria Norell
  • Patent number: 4904233
    Abstract: The present invention relates to an arrangement in a hearing aid comprising an oscillator apparatus, which via a coupling portion can be connected and anchored to the skull bone of a person with impaired hearing ability, said apparatus serving the purpose of an emitter for mechanical transmission of sound information to the skull bone.
