摘要: The invention provides progressive addition lenses in which lens unwanted astigmatism is reduced and channel width through the intermediate and near vision zones is increased as compared to conventional progressive addition lenses. This result is achieved by combining two or more progressive addition surfaces, which surfaces in combination provide the dioptric add power of the lens.

摘要: A modular color changer provides selected paint colors for spraying and recirculates nonselected colors. A module is provided for each paint color to be selected, and each module has an inlet for connection with a respective supply of paint, a recirculate outlet, a delivery outlet and a single valve member. The valve member may be selectively engaged with either a first or a second seat, depending upon whether paint at the inlet is to be directed to the recirculate outlet for return to the supply or to the delivery outlet for flow to a paint applicator. Solvent and air purge valves are upstream of the modules for cleaning the color changer of one color of paint in preparation for supplying another.

摘要: A coating applicator has a rotary atomizer detachably mounted directly on a front end of a rotor of an air driven turbine for convenient removal and cleaning of the atomizer. The rotor and atomizer are forward of bearings that rotatably mount a shaft for supporting the rotor, which isolates the bearings from coating material delivered to the atomizer, and turbine exhaust air augments shroud air in shaping the pattern of atomized material.

摘要: A rapidly cleanable rotary atomizer is characterized by a passageway extending between a rearward coating material cup of the atomizer and a forward coating material feed surface, from an edge of which atomization occurs. The passageway initiates in the material cup at a non-zero radius from the atomizer axis and terminates on the material feed surface at the axis. During changes of coating material, the passageway enables flushing media to be introduced from the material cup onto the material feed surface immediately at the axis of rotation of the atomizer for quickly and thoroughly cleaning the entirety of the material feed surface.
