Abstract: A mutant virus for use as a vaccine, wherein the genome of the virus is defective in respect of a gene essential for the production of infectious virus. In one aspect the mutant virus is capable of protecting a susceptible species immunized therewith against infection by the corresponding wild-type virus. In another aspect, the mutant virus acts as a vector for an immunogenic protein derived from a pathogen and which is encoded by foreign DNA incorporated in the mutant virus. The mutant virus can be produced in a recombinant host cell which expresses a gene complementing the defect. The mutant virus is preferably infectious for the host to be protected, but the defective gene allows expression in the infected host of at least some of the viral genes, which can provoke a cell-mediated immune response.

Date Feb. 16, 1995The invention relates to a method in a sequential bending furnace for bending glass sheets. According to the method, carriages are advanced in the furnace into a section downstream in the traveling direction of the carriages for a subsequent bending cycle essentially by using at least two transfer assemblies, providing a transfer mechanism and including first and second locking elements which are in a transfer-force transmitting relationship during the course of a transfer. This is followed by disengaging the locking elements and then transfer and locking rods included in the transfer assemblies are returned to a transfer commencing position in such a manner that at least one transfer assembly is in a locking position during transfers. Finally, the second locking elements included in the transfer and locking rods returned to the position for commencing a transfer of the carriages are clamped to the first locking elements of the carriages for a subsequent transfer of the carriages effected between the sections.
