Heat resistant thermosetting prepolymers are prepared by reacting one or more methylated pyridines or pyrazines with one or more aromatic dialdehydes, and isopropenyl phenols. The prepolymers can be further reacted with bismaleimides to make prepolymers with lower cure temperatures and faster cure rates. The total number of methyl groups on the pyridine or pyrazine can vary from 2 to 4. The prepol...

The invention concerns a decapitating apparatus for fish in which the fish to be processed is conveyed by entrainers essentially transverse to its axis and by fixing its longitudinal position by a holding element engaging the eye-hole and accompanying the fish. For adjusting the holding element a guide bar is arranged for engaging the holding element in a guiding manner in the region of a severing...

Solid particles or viscous liquid droplets of core material (27) are encapsulated in a coating material (21) largely as single particles with a single coherent coating, by feeding a suspension of the two materials onto a rotating surface (13). The suspension is centrifugally dispersed by the rotating surface into relative large coated particles (27, 27a) and relatively small droplets (21a) of coat...

Transformed human lymphocyte cell lines have been produced which secrete human monoclonal antibodies to serotypic determinants on LPS molecules of gram-negative bacteria. These antibodies have been found to be protective against lethal challenges of the homologous bacteria. Pharmaceutical compositions containing these antibodies and their prophylactic and therapeutic use in the management of gram-...
