  • Patent number: 8752125
    Abstract: There is disclosed an authentication method comprising requesting a user of a personal mobile terminal to enter a personal code into a personal mobile terminal in response to receipt of an authentication request transmitted to the personal mobile terminal, the authentication request being related to an action that requires user authentication, and processing an entered personal code together with challenge data corresponding to the authentication request to determine whether one or more predetermined conditions are met and, if one or more predetermined conditions are met, producing a valid and signed authentication code that the user can provide in order to authenticate the action.
    Type: Grant

  • Patent number: 6152210
    Abstract: Twin roll caster for casting metal strip comprises casting rolls (11) between which is formed a casting pool (16) of molten metal. The casting pool is confined at each end of the roll nip by end closure plate (22). Alternating electric current is supplied to electrical conductors (33) disposed outside the closure plate (22) so as to generate an electromagnetic field which extends through the closure plate and pushes back molten metal at the conjunctions (27) between the closure plate (22) and the rolls (11).

  • Patent number: 6106620
    Abstract: A hot dip coating pot (2) having a strip inlet passage (3) and electro-magnetic plugging means to prevent leakage of bath liquid form the pot through that passage, wherein: the plugging means comprises two magnetic field generator (7) disposed one on each side of the passage; each generator projects an oscillating magnetic field into the passage from at least two poles of opposite polarity that are adjacent the passage and spaced apart in the through direction of the passage; the said at least two poles of each generator are respectively in substantial alignment with the corresponding poles of the other in the transverse direction of the passage; the magnetic field projected by the generators have flux patterns which are substantially mirror images with reference to a plane of reflection coinciding with a centre plane of the passage; and both generators operate at a frequency of more than seven kiloHertz. When no strip is present the fields combine and extend transversely of the passage.

  • Patent number: 5845699
    Abstract: Twin roll casting of metal strip by introducing molten metal between chilled casting rolls (16) to form casting pool supported on the rolls and confined by refractory end closures (56), and rotating the rolls (16) so as to cast a solidified strip delivered downwardly from the nip between the rolls (16). Prior to casting refractory end closures (56) are preheated by positioning adjacent their inner faces a pair of metal plates (130) and exposing those plates to electromagnetic fields to cause them to rise in temperature and so heat the closures (56). Plates (130) have hooked top flanges (131) for location on the refractory end closures (56).
