Abstract: An interdental cleaning tool composed of a U-shaped arch and a handle, which can be used with various types of dental floss. The tool is made of a stainless steel wire, and hence can be used repeatedly. Two ends of the U-shaped arch part of the floss holder are each provided with a ring groove, and the dental floss is wound around the ring grooves to ensure that the dental floss will not come loose. A gap is provided at an end of the handle between two segments of the steel wire of which the handle is made, and the two segments of the steel wire of the remaining part of the handle should be tightly attached together. Following winding, the end of the dental floss is clamped in the gap in the middle of the handle for fixation.

Abstract: A lubricant contains alcohol initiated propylene oxide homopolymer, an oil soluble polyalkylene glycol other than the alcohol initiated propylene oxide homopolymer, and a calcium salt of dinonylnaphthalene sulphonate where the lubricant is further characterized by containing less than ten weight-percent of polyol esters based on total lubricant weight is useful as a lubricant for compressors.

Abstract: A concentrated metalworking fluid comprising from 60 to 90 percent by weight base oil selected from the group consisting of water soluble polyalkylene glycols, methoxypolyethylene glycols, polyethylene glycols, and combinations of two or more thereof; from 5 to 20 percent by weight glycol ether; from 0.01 to 5 percent by weight oil soluble polyalkylene glycol; and from 0.2 to 6 percent by weight one or more additives selected from the group consisting of anti-weld agents, corrosion inhibitors, extreme pressure additives, buffers, biocides, lubricity additives, and combinations of two or more thereof is provided. Further provided is a metalworking process.

Abstract: An oil in water lubricant fluid for use in steel cold rolling, comprising an oil in water emulsion having a particle size of 1 ?m or less, consisting of an oil phase and water, where the oil phase includes about 5 wt % to about 40 wt % of at least one polymeric surfactant, about 25 wt % to about 95 wt % base oil, about 0.2 wt % to about 10 wt % extreme pressure lubrication additives, and about 0.5 wt % to about 6 wt % other functional additives.
