Abstract: A rebar forming apparatus includes a malleable material supply station for continuously supplying a malleable planar material and a malleable material forming station for forming the malleable material into first and second corresponding shell portions and related rebar products. The apparatus also includes a core pultrusion station and a cladding forming station for respectively forming core and cladding layers. A shell forming station is positioned downstream of the core and cladding forming stations which unites the first and second shell portions to form an outer shell with the core and cladding layers contained therein. The rebar product includes shell portions which are matably configured to form a disposable outer shell over the core and cladding layers. Related reinforcing composite product forming methods also include the use of a removable outer shell.

Abstract: Methods, systems and computer program products are provided for transferring a Virtual IP Address (VIPA) from a first application instance to a second application instance executing on a cluster of data processing systems having a plurality of communication protocol stacks. A list of dynamic VIPAs is distributed among the protocol stacks and a hierarchy of backup communication protocol stacks for the dynamic VIPAs is determined based on the list of dynamic VIPAs. Upon receiving notification of failure of the first stack the second stack evaluates the hierarchy of backup stacks to determine if it is the next stack in the hierarchy for the VIPA associated with the first application instance. If so, then the VIPA associated with the first application instance is transferred to the second communication protocol stack associated with the second application instance.
