A working fluid composition for a refrigerating machine, containing: a refrigerant containing trifluoroiodometbane; and a refrigerating machine oil containing a polyol ester and a hindered phenol compound, wherein a content of the hindered phenol compound is 0.6 to 10% by mass based on a total amount of the refrigerating machine oil.

A method for improving wear control in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and encapsulated boron-containing microscale particles, as a minor component. The minor component preferably contains no metal or sulfur, and preferably no phosphorus. The encapsulated boron-containing microscale particles include an encapsulating material and a boron-containing compound encapsulated by the encapsulating material. The boron-containing compound is a boron oxide, a boric acid, or mixtures thereof. The encapsulating material is a carboxylic acid selected from an aliphatic carboxylic acid, a cycloaliphatic carboxylic acid, an aromatic carboxylic acid, and mixtures thereof. The lubricating oils are useful in internal combustion engines.

A sliding screen system (101) for a sliding screen comprising a linear slide bar (110) and at least one sliding member (120, 120). The linear slide bar (110) has a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide bar (110) with low friction. The sliding system (101) is arranged to support a sliding screen (130), such as a sliding door or a sliding curtain, connected to the sliding member (120) to allow for linear movement of the sliding screen (130) along the longitudinal axis of the linear slide bar (110).

Provided are microalgal compositions and methods for their use. The microalgal compositions include lubricants that find use in industrial and other applications.

The purpose of the present invention is to provide organometallic salt compositions that are useful as lubricant additives and/or in lubricant additive compositions to reduce friction and wear, and also have improved solubility in all four types of hydrocarbon base oils (Groups I-IV) at a variety of concentrations and under a variety of conditions. The organometallic salt composition is derived from at least one long chain monocarboxylic acid and a single metal in combination with at least one short or medium branched-chain monocarboxylic acid. The compositions are particularly useful in combination with activated complexes comprising a first metal component, a second metal component and particles comprising the first metal component.

A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate)), as a minor component. The lubricating oils are useful in internal combustion engines.
