Abstract: A coated substrate is disclosed, including a solvent-sensitive substrate and a polyester coating disposed on the solvent-sensitive substrate, wherein the polyester coating includes a polyester copolymer of a polyol and a polyacid. A method for forming a coated substrate is disclosed including spraying solvated polyester material from a spray nozzle onto a solvent-sensitive substrate and drying the solvated polyester material to form a polyester disposed on the solvent-sensitive substrate, wherein the solvated polyester material and the polyester coating include a polyester copolymer of a polyol and a polyacid.

Abstract: A traffic signal system for congested trafficways has a plurality of stationary alarm light/sensor-reader combinations and mobile alarm light/sensor-reader combinations monitoring each other and monitory tags placed on individuals, machines, and hazards to provide real time alarms to not only pedestrians but also machine operators, who are potentially approaching harm's way, or have the better ability to avert potential harm. Different forms of alarms are provided to indicate different kinds of alarm conditions and to reduce complacency to alarms, and thus improve effectiveness.

Abstract: A drainage installation (20), for a warehouse and/or factory floor that has a surface level (26), has a drainage channel (24) recessed into the floor and a plurality of sections of flat grating (22) seated inside the drainage channel (24). The drainage channel (24) has an axially-elongated, square-U shaped channel portion which is flanked by horizontal shoulders (30), which then transition into vertically-depending skirt portions (32). The horizontal shoulders (30) as well as the sections of flat grating (22) are arranged to be more less planar with the surface level (26). Wherein, the skirt portions (32) are formed with a series of apertures (36) which either allow the injection of wet cement underneath the shoulder portions (30) of the drainage channel (24), or alternately the venting of the wet cement when the cavity under the shoulder portions (30) are over-filled.
