Abstract: A rigid composite panel 10 for insulating an installation such as a furnace or cooler (HVAC units). The panel 10 has a thermally insulating core 20, at least two laminate assemblies 30 which are bonded to the core 20 thus forming a sandwich, and an edge band 40 adhesively applied to the edges of the sandwich 50 so as to provide a smooth, continuous, and impermeable seal around said edges. There is also claimed a method for manufacturing a rigid composite panel 10 having an edge band 40, each laminate assembly being pretreated by plasma before the edge band 40 is bonded to the panel 10. Each laminate assembly 30 consists of a thin layer of polymer 38, as well as sheets 36 bonded to the surfaces of the layer 38.

Abstract: A method, system and storage medium for monitoring power control loops in an optical communication network. The method includes polling network elements to obtain power management information for the network elements. A set of power management rules is selected based on the power management information along with network configuration, channel types, etc. The power management rules are applied to determine the validity of open and closed power control loop in the network elements.

Abstract: A power-operated and hand steerable machine for stripping linoleum, tile, mastic, grout, adhesive and the like from a floor and also for re-surfacing the floor after the stripping operation. The machine includes a support frame, a drive plate driven by a motor about a vertical rotational axis, a reversible work plate mounted under the drive plate and carrying cutter blocks with cutter inserts at one face and abrasive-carrying devices at the opposite face. Therefore, after a floor stripping operation by the cutter inserts, the work plate can be reversed and a floor re-surfacing operation be carried out by using the abrasive-carrying devices. A change speed system enables to drive the work plate at a higher speed during floor re-surfacing than during floor stripping. Longitudinally adjustable weights are carried by the support frame to adjustably bias the work plate against the floor.
