Coating is removed from polyester film which is formed into flakes by use of an alkali stripping solution containing surfactant wherein the surfactant is not optimized in a stripping step to remove redeposited coating but rather is optimized to aid in rinsing based on residual surfactant present on the stripped flake.

An automatic steering system which reduces formation of a wheel track by changing a relative position of a vehicle (10) with respect to a road. A reference line (13) is provided along a road so that the vehicle (10) moves along the reference line. The vehicle moves on the road while an amount of shift from the reference line (13) is controlled to be equal to a target amount of shift. The amount of...

A platoon running control system which is able to recognize the position of a vehicle within a platoon and to appropriately respond to a change, for example, when another vehicle leaving the platoon. If the vehicle is not in a platoon running mode, a communication control ECU assigns an ID = 1 to the vehicle, and a vehicle control ECU operates the vehicle in an auto-drive mode based on a signal su...

A biaxially-oriented polymer film having dual-sided appearance, i.e., the color of each side is chromatically different. Also a method for making such films.

The addition of additives, in particular colourants, to polyesters such as polyethyleneterephthalate is achieved by dissolving or dispersing the additive into an ester of an alcohol and a substantially straight chained fatty acid having from C14-C22 carbon atoms. The advent of a liquid colourant has particular advantages to the food packaging industry. The preferred carrier is the ester of oleic a...

The operational fitness of a vehicle-mounted magnetic sensor (90) for detecting buried magnets which identify zones of operation of the vehicle can be tested from time to time by an electromagnet (92) installed in proximity to the sensor. The electromagnet is a small coil of wire mounted near the sensor, such as a Hall effect device, which when energized, generates a test magnetic field. The analo...

A method of producing an open cell rigid polyurethane foam which comprises reacting a polymethylene polyphenylisocyanate prepolymer with a polyol at an NCO/OH equivalent ratio of 1.3 to 3.0 by use of a blowing agent substantially comprising water in the presence of a catalyst, a foam stabilizer and a cell opening agent.

A polymeric film has a polyester substrate layer and an adherent layer of an acrylic resin and a phthalate ester. The adherent layer preferably contains an additional cross-linking agent. The adherent layer exhibits improved adhesion to the substrate and to a range of subsequently applied layers, such as inks and lacquers, vinyl chloride polymer.
