Abstract:
Complex sulfides of antimony combined with either molybdenum disulfide or graphite are used as mixtures to impart synergistic effects in imparting extreme pressure and antiwear properties to lubricants.
Abstract:
A lubricant additive for gear oils and an improved gear oil are disclosed. The additive comprises about 0.01 to about 65 percent, by weight, of solid lubricant particles selected from the group consisting of molybdenum disulfide, graphite, cerium fluoride, zinc oxide, tungsten disulfide, mica, boron nitrate, boron nitride, borax, silver sulfate, cadmium iodide, lead iodide, barium fluoride, tin sulfide, fluorinated carbon, PTFE, intercalated graphite, zinc phosphide, zinc phosphate, and mixtures thereof; combined with about 0.1 to about 25 percent, by weight, of a stabilizing agent consisting of an ethylene-propylene copolymer; and a fluid carrier. The lubricant additive provides the gear oil with improved demulsibility, stability, and compatibility characteristics of the gear oil when contaminated with water.

Abstract:
The pasty damping agent is used to damp mechanical and/or acoustic oscillations. The agent contains as a minimum compound a solid finely divided substance or a mixture of solid finely divided substances, as a liquid phase, a silicone oil, a polyglycol, a mineral oil and/or a saturated or aromatic aliphatic carbon dioxide ester, an agent for increasing the activity of the limit layer or a surfactant, a magnesium and/or aluminum silicate and/or a silicon dioxide finely divided as a viscosity stabilizer and possibly a small quantity of an empty oxidiser. The damping agent is used in different hydraulic damping devices or for industrial vibration shock absorbers.
Abstract:
Fluid concentrates for aqueous functional fluids useful in hydraulic systems or as metalworking compositions contain
(a) a cloud point raising metal dialkyldithio-phosphate additive having the following structural formula: wherein R 1 , R 2 , R 3 , and R 4 are individually linear or branched alkyl, alkenyl, aryl, arylalkyl and alkylaryl groups having from 1 to 24 carbon atoms; and M is Zn, Sb, Sn, Mg or Mn; preferably Zn or Sb; (b) a polyether nonionic surfactant; and (c) an associative polyether thickener.
Abstract:
The apparatus comprises a first pair of photosensors (50E, 80W) arranged at symmetrically opposed positions on a first horizontal axis (16) rotatable around a third vertical axis (14), and a second pair of photosensors (50N, 50S) arranged at symmetrically opposed positions on a second axis (18) perpendicular to and rotatable around the first axis. To the first and third axes are connected driving means which operate when there are differences in outputs between the first pair of photosensors and between the second pair of photosensors, respectively.
