Abstract: The invention relates to composite sleeves for producing a cured in place pipe, to materials and methods for producing the composite sleeve, to methods for repairing a native pipe with the composite sleeve, and to improved cured in place pipes. The composite sleeve has multiple layers including a core layer of a curable one-part resin composition. The curable one-part resin composition is a solid material at 25° C. Preferably the resin composition is pliable at 25° C. so that it can be flexed during manufacturing and/or during installation in a native pipe.

Abstract: A system for performing a function with respect to a zone includes a controller, a network, and a plurality of subsystems. The controller issues a first series of commands. Each command of the first series has a first ordinal. The plurality of subsystems is coupled to the controller via the network. A particular subsystem determines a role in accordance with a physical position of the particular subsystem relative to another subsystem of the plurality of subsystems. The particular subsystem counts commands of the series to determine for a particular command the first ordinal. The particular subsystem performs a function with respect to the zone in accordance with the particular command of the series, in further accordance with the first ordinal, and in further accordance with the role.
