20130068564Lube by Number - An architecture is presented that provides a lubricating kit that discloses an easy to follow system of product application. The lubricating kit comprises a lubricating guide and a purpose built case for housing the lubricants. The lubricating guide provides lubrication instructions and identifies each product and surface where each product is applied. The purpose built case comprises all types of industrial lubricants that technicians or other lubricant users may need. The lubricants comprise product labels that follow the lubrication guide. Specifically, the product containers of the lubricating kit are color coded and numbered to correspond with the colors and numbers on the lubricating guide, thus allowing a user to identify a specific product for a specific surface and purpose. Thus, the lubricating guide identifies a surface in need of lubrication, recommends a specific product for the task, and provides basic application directions and durability estimates.03-21-2013
20090211852Self-lubricating fasteners - Self-lubricating fastener devices with interlocking rails or interlocking members of a polymer and a slip system additive with a roughening agent and lubricant dispersed throughout the polymer are provided. Methods for production of self-lubricating fastener devices and their use in liquid-resistant or liquid-proof articles are also provided. A particular advantage is the ability of the devices to repeatedly reestablish a self-lubricated surface, even after solvent cleaning.08-27-2009
20080277203ADDITIVES AND LUBRICANT FORMULATIONS FOR IMPROVED PHOSPHORUS RETENTION PROPERTIES - A method and compositions for lubricating surfaces with lubricating oils exhibiting increased phosphorous retention. The lubricated surface includes a lubricant composition containing a base oil of lubricating viscosity, an amount of a phosphorus-containing compound and an amount of at least one hydrocarbon soluble titanium compound effective to provide an increase in phosphorus retention of the lubricant composition greater than an increase in phosphorus retention of the lubricant composition devoid of the hydrocarbon soluble titanium compound.11-13-2008
20090065306LUBRICATING OIL SUPPLY DEVICE - A lubricating oil supply device includes a casing including a cylindrical bore and a guide passage whose one end opens to an inside of the casing and whose the other end opens to the cylindrical bore, a rotational shaft including a center bore, an accommodating groove, and a discharge passage which corresponds to the guide passage and whose one end opens to the accommodating groove and whose the other end opens to the center bore, and a lubricating oil guiding member accommodated within the accommodating groove and including a cylindrical portion, a guide hole, which has a first inner side surface connected to an outer circumferential surface of the cylindrical portion so as to form an angle therebtween and a second inner side surface and which is always connected to the discharge passage, and a guide groove extending along the outer circumferential surface of the lubricating oil guiding member.03-12-2009

Each automatic grease dispenser comprises a driving mechanism for driving a piston to dispense the lubricating grease, a microprocessor-based control unit for the setting of the lubricating cycle and for checking the grease dispensing amount subject to the detection of the rate of turn of the driving mechanism through a sensor and a black and white reflective plate.10-20-2011
184004000 WINDMILL LUBRICATION 1
20120211307LUBRICATION SYSTEM FOR A GEAR SYSTEM PROVIDING EMERGENCY LUBRICATION - A lubrication system for a gear system for a wind turbine is disclosed. The lubrication system comprises a reservoir adapted to contain lubricant, first pump means arranged to supply lubricant from the reservoir to the gear system via a first fluid connection, and vacuum generating means arranged in fluid connection with the reservoir, thereby maintaining a total air pressure in the reservoir which is lower than an ambient pressure during normal operation. The lowered total air pressure in the reservoir draws lubricant from the gear system into the reservoir, thereby increasing the lubricant level in the reservoir and decreasing the lubricant level in the gear system, allowing the lubrication system to be operated in a ‘dry sump mode’. In the case of an emergency or during start-up the vacuum generating means is stopped, thereby increasing the total air pressure in the reservoir. This causes a decrease in the lubricant level in the reservoir and an increase in the lubricant level in the gear system, allowing the lubrication system to be operated in a ‘wet sump mode’.08-23-2012
