Abstract: A polymer based coating for application to rolled stock, such as aluminum is provided. A device for applying the polymer based coatings is also provided. Polymer based coatings applied to rolled stock, such as aluminum, are advantageous compared to anodized coatings since the polymers are self-leveling and may be applied to lower grades of aluminum, while still providing a smooth and durable surface finish.

Abstract: A reflector formed on a polished aluminum base which is lightly anodized (0.2-0.5 microns thick) as a protective coating over which is vacuum deposited a thick (0.05 to 2.0 microns) layer of non-porus oxide underlying an aluminum reflectance layer which supports a pair of quarter wave length reflectance-enhancing layers.

Abstract: Improvements in the method and apparatus of vacuum deposition of a highly reflective surface onto aluminum base, including unanodized roll-polished aluminum, wherein a coil of the aluminum is disposed within the vacuum chamber, both as it unwinds and as it rewinds, and the water vapor created by heating the aluminum web is made available to other vacuum deposition processing compartments within the vacuum chamber including a glow discharge chamber typically fueled by argon gas. A relatively thick layer of oxide is vacuum deposited onto an unanodized aluminum base as a substrate for the reflective surface.

Abstract: Improvements in the method and apparatus of vacuum deposition of a highly reflective surface onto aluminum lighting sheet wherein a coil of aluminum is disposed within the vacuum chamber, both as it unwinds and as it rewinds, and the water vapor created by heating the aluminum web from the coil is made available to other vacuum deposition processing compartments within the vacuum chamber including a glow discharge chamber normally fueled by argon gas.

Abstract: Apparatus and method for increasing the time that a quartz crystal can sense the rate at which evaporated material is broadcast onto a substrate wherein a chopper employing a disk with a slot is disposed between the source of the evaporated material and the crystal to reduce the exposure of the crystal to evaporated material to a fraction of the time that the substrate is exposed wherein the chopper frequency is not in tune with the dither frequency of the material evaporator. Barrier means prevents the chopper slot from significantly changing dimensions due to the build up of material on its defining edges, while shield means prevents the a crystal from being exposed to evaporated material from a source that it does not control.
