A fluid display arrangement is disclosed for a rolling-traction continuously-variable ratio transmission unit in which drive is transmitted from one race to another by at least one rotating roller whose outer circumference engages the races, the fluid supply arrangement comprising a shroud mounted in proximity to the roller and a fluid supply conduit, and being characterised in that the shroud has an inner surface providing a circumferential portion adjacent the roller's outer circumference and two radially extending portions adjacent respective flanks of the roller, a fluid receiving chamber being thereby defined between the roller and the shroud, and the fluid supply conduit being arranged to deliver fluid into the fluid receiving chamber.

A lubricant composition, uses for the lubricant composition, and methods of lubricating devices using the lubricant composition. The lubricant composition includes base oil component having a first base oil derived from a gaseous source, and optionally, a second base oil derived from a liquid petroleum source. The base oil component of the lubricant composition includes from about 5 to about 100 percent by weight of the base oil derived from a gaseous source. An additive and a solubilizing agent selected from the group consisting of an adipate ester, a polyol ester, an alkylated naphthalene, an alkylated sulfone, a naphthenic base oil, an aromatic base oil, an akylated benzene, and a combination of two or more of the foregoing agents are also included in the lubricant composition.

A clean performing gear oil for use in transmission oils and axle lubricants is provided. The gear oil having a Brookfield Viscosity at -12.degree. C. ranging from about 1,000 to about 150,000 cP, comprises a base oil having a kinematic viscosity at 100.degree. C. ranging from about 4.0 to about 41.0 cSt. Combined with the base oil is preferably a dispersant pour point depressant and/or a dispersant viscosity index improver. In a further preferred embodiment, the gear oil is essentially devoid of carboxylic-type ashless dispersants (e.g., succinimide dispersants) and Mannich base dispersants, thus realizing a cost saving over conventional gear oils which are used as transmission and axle lubricants. Functionalized polymethylacrylates (PMA) are disclosed as agents that improve the properties of the gear oil and allow for the omission of conventional dispersants.

Certain hydrogenated oligomers of 1-alkene hydrocarbons have been found to be substantially biodegradable upon exposure to microbiological agents of types widely available in the environment. Thus, in an operation wherein lubricating oil or functional fluid is released into the environment, there is provided for use as the lubricating oil or functional fluid a substantially biodegradable lubricating oil or functional fluid at least 10 percent by volume of which is composed of at least one substantially biodegradable liquid hydrocarbon of lubricating viscosity formed by oligomerisation of 1-alkene hydrocarbon having 6 to 20 carbon atoms in the molecule and hydrogenation of the resultant oligomer.
摘要:
Hydrolytic degradation of oleaginous fluids susceptible to hydrolytic degradation in the presence of moisture and the development of acidity in adventitious water are inhibited by including in the oleaginous fluids at least one oil-soluble compound containing at least one 3,5-dihydrocarbyl-4-hydroxybenzyl group attached to a primary, secondary or tertiary amino nitrogen atom, the two alpha-positions of the benzyl group being substituted by two hydrogen atoms, by two organic groups, or by one hydrogen atom and one organic group. Other phenolic compounds such as hindered phenolic antioxidants are incapable of providing such protection against hydrolytic degradation and acid buildup.

The disclosure is directed to a method of enhancing a fuel value for a used or waste lubricating oil, lubricating oils having improved combustion and emission characteristics, and a business method for distributing and using waste oils as components of primary combustion fuels. In one embodiment, there is provided a lubricating oil composition having improved combustion and emission properties when burned as a used lubricating oil composition. The lubricating oil composition includes a major amount of oil of lubricating viscosity and a minor combustion improving amount of a combustion improving additive.
摘要:
Lubricants and additive packages that give exceptional performance as heavy duty gear lubricants are described. Four essential oil-soluble additive components are used in combination, viz., a metal-free sulfur-containing antiwear and/or extreme pressure agent having a copper corrosion test activity of not more than 65; a metal-free phosphorus- and nitrogen-containing antiwear and/or extreme pressure agent; an organic carboxylic acid; and an organic amine. Tests comparing the performance of the invention against a commercial premium API GL-5 gear oil additive package selected as the best available package by a well-known OEM have shown the superiority of the present compositions under a number of test conditions.
摘要:
A gear oil composition, a method for operating an automotive gear, and a method for improving performance of a gear oil that includes a) a major amount of a base oil having a lubricating viscosity; b) a polysulfide extreme pressure agent; and c) a reaction product of an acylated copolymer and a polyamine.
摘要:
An apparatus for the removal and replacement of a lid on a metallurgical transport vessel such as a ladle or a torpedo car. The apparatus comprises a frame, means for supporting the frame such that the vessel may be moved into position thereunder, a linkage including at least one lifting member pivotally connected to the frame, and at least one actuator connected to the linkage. The actuator is operable to move the lifting member such that when the vessel is moved to a designated position below the apparatus, the lifting member can be moved by the actuator and linkage from a first position providing clearance above the vessel, through a curved path to an intermediate position where it engages the lid, providing a vertical lifting force and a horizontal hinge releasing force to the lid, and to a second position where the lid is raised to a sufficient height to clear the vessel. The lifting member may subsequently be moved back by means of the actuator and linkage through a reverse curved path to the first position, and thereby lower the lid back on to the vessel.
