摘要： Automatic transmission fluids are described which contain a dispersant having a nitrogen to phosphorus mass ratio between about 3:1 and about 10:1, and at least one friction modifier. The use of dispersants having a nitrogen to phosphorus mass ratio between about 3:1 and about 10:1 provides automatic transmission fluids which exhibit good anti-shudder properties as well as a higher mid-point torque, a higher static torque in shifting clutch applications and better frictional durability as compared to similar automatic transmission fluids which contain dispersants having a nitrogen to phosphorus mass ratio of less than 3:1.

摘要： A system and methodology for building highly scalable Network Management Systems (NMS)s for the management of large voice and data networks is provided. The NMS of the present invention is designed to manage a plurality of network elements communicating through network controlled links. The elements are combined into management groups of no more than n elements. A first functional subsystem controls and manages the communication functions associated with a first group of elements. Each function or process inside the subsystem is guaranteed to communicate with only one instance of every other type of process or function. As additional network elements are added to the system, additional management groups are also added, one functional subsystem for every management group of elements. The plurality of other functional subsystems are substantially the same as the first functional subsystem. Limiting the management process to intra-subgroup communications greatly simplifies expansion of the system. When a total of m management groups exist, at least (m−1) functional subsystems are replicated from the first NMS subsystem. Thus, the network is scaled up by using size-limited subsystems.

摘要： A "cold-clash" gear problem associated with vehicular manual transmissions exposed to the cold is overcome by use of a special all-synthetic gear oil composition. The composition is composed of base oil and specified additive components. The base oil is a blend of dialkyl ester of an aliphatic dicarboxylic acid having a maximum pour point of about -55.degree. C. and a maximum kinematic viscosity at 100.degree. C. of about 4 cSt, and three hydrogenated poly-.alpha.-olefin oligomers having kinematic viscosities at 100.degree. C. of about 40, about 4-8 cSt and about 2 cSt in specified proportions. The additive components comprise an organic sulfur-containing antiwear and/or extreme pressure agent, an organic phosphorus-containing antiwear and/or extreme pressure agent, a copper corrosion inhibitor, a rust inhibitor, a foam inhibitor, and an ashless dispersant. The gear oil has a boron content of about 0.0025 to about 0.07 wt %.

摘要： A novel a multi-functional polymer viscosity modifier comprising an additive reaction product obtained by reacting a first monomer comprising an alkylacrylate with a second monomer comprising an olefinic carboxylic acylating agent under conditions effective for free radical polymerization of the first and second monomers to provide a base polymer comprising an acylated alkylacrylate copolymer, and wherein the base polymer optionally may be further reacted with an amine compound to provide a multi-functional polyalkylacrylate copolymer. The base polymer has good thickening efficiency. The multi-functional polyalkylacrylate copolymer dispersant viscosity modifier has good thickening efficiency. The base polymer and the multi-functional polyalkylacrylate copolymer viscosity modifier have good thickening efficiency, low temperature properties, dispersancy, and antioxidancy properties. They also have no precipitation or sedimentation, nor cause or encourage such formations in finished fluids incorporating them.
