Abstract: The present invention describes a pipe sealing compound/adjunct lubricant used to prevent gas or liquid leaks when applied to pipe threads and other connections of the same. The compound relies on silicone oil lubricant(s) and one or more friction modifier(s), viscosity builder(s) and filler material(s). The compound contains a viscoelastic liquid that does not have a curing phase and is resistant to hardening and/or drying. The compound is chemically resistant to a wide variety of liquids and gases, is food safe and can withstand extreme high or low temperatures and precipitous temperature fluctuations. The compound has been found to exhibit an inverse pressure to leak rate phenomena.
Abstract: An additive concentrate package for a marine engine cylinder lubricant is made by mixing an oil of lubricating viscosity, a metal detergent and an oil-soluble alkoxylated alcohol.

Abstract: A grease composition is disclosed which is intended primarily for use in constant velocity joints (CV joints), especially ball joints and/or tripod joints, which are used in the driveline of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, at least one thickener, zinc sulfide, at least one copper sulfide and molybdenum disulfide and/or tungsten disulfide. Further, the present disclosure relates to a constant velocity joint comprising such a grease composition.
Abstract: A first wafer has a first stop layer deposited on a substrate, the substrate used to form a base support structure. A second wafer has a second stop layer deposited on a sacrificial substrate, and a filter layer deposited on the second stop layer. A rib layer is deposited on one of: the first stop layer of the first layer; or a third stop layer that is deposited over the filter layer. A rib pattern is formed in the rib layer. The first and second wafers are flip bonded such that the rib pattern is joined between the filter layer and the first stop layer. Elongated voids are formed within the filter layer. The base support structure is formed within the substrate of the first wafer such that there is a fluid flow path between the base support structure, the rib layer, and the elongated voids of the filter layer.
