Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition.

Abstract: A ball valve includes a body having a passageway there through with a ball member disposed in the passageway and mounted for selective rotation between valve open and valve closed positions to control fluid flow. A pair of flange grooves are provided in the body on opposite sides of the ball, each flange groove extending radially from the passageway. A pair of seat rings are disposed in the passageway on opposite sides of the ball. Each seat ring has a first sealing surface in contact with an outer surface of the ball and a radially extending annular flange or tab received in an associated one of the flange grooves. The seat design further includes a pair of annular flange seals each disposed in a respective one of the flange grooves. The seat configuration achieves a cantilever effect to improve the temperature and pressure cycling performance of the valve.

A pair of seat rings (16) are disposed in the passageway on opposite sides of the ball. Each seat ring has a first sealing surface (24) in contact with an outer surface of the ball and a radially extending annular flange or tab (30) received in an associated one of the flange grooves (34). The seat design further includes a pair of annular flange seals (18, 20) each disposed in a respective one of the flange grooves.

Abstract: An onboard unit consisting of a tape recorder, and associated data handling components utilized to provide records of vehicular operating information including speed, distance, power level, braking level, traction motor current and other control events. Each quantity is associated with an incremental distance and/or time which is fixed. In the case of a rail guided vehicle, location signals provided by ground mounted markers are also recorded. Summation of incremental distances as determined from each marker provides an exact location. A magnetic tape unit provides both data storage and operations instruction for a microprocessor based system, allowing convenient alteration or variations in unit function without internal modification. Each unit retains a unique non-volatile serial number which is transferred to each tape allowing convenient correlation of recorded tapes to onboard units.

Abstract: A dual flexible drive is pprovided between a torque converter and a transmission to compensate for parallel misalignment therebetween. The flexible drive includes a coupling having a drive tube with enlarged flanges and with laminated flexible plates secured to said flanges and to the output of the torque converter and to the input of the transmission. Pilot guides are provided between the inner and outer periphery of the flexible plates.
