Abstract: A packet communications system provides for point-to-point packet routing and broadcast packet routing to limited subsets of nodes in the network, using a routing field in the packet header which is processed according to two different protocols. A third protocol is provided in which a packet can be broadcast to the limited subset even when launched from a node which is not a member of the subset. The routing field includes a first portion which contains the route labels necessary to deliver the packet to the broadcast subset. A second portion of the routing field contains the broadcast subset identifier which can then be used to deliver the packet to all of the members of the broadcast subset. Provision is made to backtrack deliver the packet to the last node identified before the broadcast subset if that last node is itself a member of the subset. <IMAGE>

Abstract: To enhance the catalytic activity of plate-type catalytic converters the invention provides that a plate-type catalytic converter comprising multiple plates (2, 4) coated with a catalytically active substance and arranged in a unit casing has means (6, 14, 16, 20, 22) for diverting the flow medium from a main flow direction (12) at least partly within the same reaction space (24, 26) and at least partly into adjacent reaction spaces (24, 26). An alternative solution is provided by diverting the flow medium at least partly from the main flow direction (112) in at least one reaction space (106, 136) by means of a structure (108, 110, 132, 134) and arrangement of the plates (102, 104, 126, 128) or adjacent plates (102, 104, 126, 128) in relation to each other. A reaction space is delimited between every two immediately adjacent plates and the unit casing which is permeable to the flow medium on inflow and outflow sides. With the resulting high-level turbulence of the flow medium the flow guidance-induced contribution to the catalytic activity of the plate-type catalytic converter is increased. The invention can essentially be used with all plate-type catalytic converters through which a liquid or gas medium flows.
