  • Publication number: 20010009315
    Abstract: A spring assembly having a coil containing a core and methods and apparatus for manufacturing same are disclosed. The coil includes a core between reduced portions of the coil. One device for manufacturing the coil includes a coiling machine having an insert device operable with a coiler. The coiler is programmed to form coils of appropriate diameter along the length of the coil, including a diameter sufficiently large to contain the core and two diameters sufficiently small to retain the core in the coil. The insert device transfers the core to the coil after the first small diameter is formed and before the second small diameter is formed. The coil with the core contained between the two small diameters is thereby manufactured in a unified automated process.

  • Patent number: 5565094
    Abstract: An apparatus and method for removing free and emulsified water as well as solid contaminants from an oil/water mixture produced in lubricating the bearings of a steam turbine employs a singular, closed housing having a lowermost, filter-free gravity chamber, an uppermost filter element chamber, and a filter-free water collection chamber between the gravity chamber and the filter element chamber. The oil/water mixture introduced into the housing has its free water component removed in the gravity chamber and has its emulsified water and solid contaminant components removed by coalescence in the filter element chamber. Free water, emulsified water and solid contaminants are collected, monitored and selectively drained from the water collection chamber and gravity chamber.

  • Patent number: 4095803
    Abstract: The disclosure illustrates an oil seal assembly for a keyway which receives a pin for an interconnection between an accessory drive pulley and a shaft extending from a diesel engine accessory drive gear box. The oil seal consists of an L-shaped elastomeric seal with one leg of the L extending into the keyway and the other leg providing a shoulder which abuts the shaft adjacent the keyway end. A nut threaded onto the end of the shaft holds a washer against the L-shaped seal thus compressing it. So compressed, the seal expands against the walls of the keyway to form an effective seal against the flow of oil therethrough. Preferably, the seal is formed from material which swells exceedingly when immersed in petroleum products. As a result, any leakage causes the seal to expand and stop further oil flow.
