The object of the invention is a traction sheave elevator and a rope that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands laid from metal wires and which rope is lubricated with a lubricant. Another object is the use of the aforementioned lubricant for lubricating the rope. The lubricant comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant.

Compositions having a plurality of hard particles and a plurality of lubricant nanoparticles are disclosed. Methods of making and using the compositions are also disclosed.

The invention relates to water-based lubricants for conveyor belts. More particularly, the invention relates to water-based lubricants for conveyor belts for the drinks industry.

Nanoparticle compositions and greaseless coatings are disclosed, including, for example, a greaseless lubricant nanoparticle coating on drill pipe threads. The lubricant coating may be multifunctional, including, for example, anti-corrosives. The coating may be a spray, or otherwise.

An image bearer protective agent is provided. The image bearer protective agent includes a fatty acid metal salt and an inorganic lubricant. The inorganic lubricant includes a first inorganic lubricant having a tap density of from 0.30 to 0.8 g/cm.sup.2.

Compositions having a plurality of nanoparticles and nano-sheets are disclosed. Methods of making and using the compositions are also disclosed.

A functional fluid composition containing a fluid base stock (e.g., a phosphate ester fluid base stock) as a major component, and an erosion inhibitor mixture as a minor component. The erosion inhibitor mixture contains at least a first erosion inhibitor (e.g., a perhalometallate or perhalometalloidate salt) and a second erosion inhibitor (e.g., an alkali metal salt of perfluoroalkyl sulfonic acid). Erosion inhibition of the functional fluid composition is improved as compared to erosion inhibition achieved using singly the first erosion inhibitor or the second erosion inhibitor, as measured by one or more of ASTM D2624, ASTM D974, ASTM D130 and ASTM D6304. A method for operating and lubricating a hydraulic system by utilizing as a hydraulic fluid, the functional fluid composition. A method for identifying erosion inhibition effectiveness of the functional fluid. The functional fluids are useful as aircraft hydraulic fluids.

A fabrication fluid composition, such as a metal cutting fluid concentrate, contains water, a first surfactant which is an anionic surfactant, a second surfactant which is an amphoteric surfactant, a third surfactant which is selected from an anionic surfactant and an amphoteric surfactant, the third surfactant being different from the first and second surfactants, and water, along with at least one of an anti-rust agent, a coloring agent, and a de-foaming agent. The concentrate may be combined with water to provide a fabrication fluid such as a metal cutting fluid composition that may be applied to a piece of metal being cut for a time and in an amount effective to dissipate heat from the metal being cut.

Additive packages including multifunctional additive molecules are disclosed, including, for example, organic medium intercalated with lubricant nanoparticles. The additive package may be greaseless or may be added to materials such as base oils or greases, greaseless materials, or anti-corrosives, for example. The additive package added to materials may form a coating or lubricant that may be added to a surface of an object.

Lubricating compositions are provided. The lubricating compositions can include a lubricating agent, a flexibilizer, a dispersing agent, and a charge imparting agent. The lubricating compositions can optionally include a carrier.
