Abstract: A lens assembly includes a lens, a lens barrel, and a heater element. The lens has an inner surface and an outer surface. The lens barrel supports the lens and defines an optical axis, the lens arranged along the optical axis such that the inner surface of the lens is within the lens barrel and the outer surface of the lens is outside the lens barrel. The heater element is in intimate mechanical communication with the inner surface of the lens and has a heater element electrical lead extending radially therefrom to provide power to the heater element. Lens heating methods are also described.

Abstract: The present invention discloses the use of calcium sulfonate based greases compounds for use in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces such as those present in threaded connections, and, especially in threaded connections associated with oilfield applications. The present invention also discloses methods for making and using such greases and compounds in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces.

Abstract: An anti-seize compound is disclosed for use on surfaces of threaded connections made of speciality alloys such as high nickel or chrome ferrous alloys or other speciality alloys prone to galling under high stress conditions. The compound using a metal fluoride as the anti-seize film forming agent at least above about 5 wt %.
