摘要： A vehicular propeller shaft is configured to transmit a rotational force output from a drive force source to drive wheels. The vehicular propeller shaft includes a stepped pipe-shaped member including a compressive load weakest part with respect to an axial compressive load of the vehicular propeller shaft and a torsional load weakest part with respect to a torsional load around an axis of the vehicular propeller shaft. The compressive load weakest part and the torsional load weakest part are positioned apart from each other in a radial direction of the stepped pipe-shaped member.

摘要： In a mud-lubricated bearing assembly for a downhole motor, a mechanical seal is provided between the mandrel and the lower end of the bearing housing to prevent discharge of drilling fluid (mud) from the bearing assembly into the wellbore annulus. The mechanical seal is effected by mating wear-resistant annular contact surfaces provided on the mandrel and the bearing housing, with biasing means preferably being provided to keep the contact surfaces in sealing engagement during both on-bottom and off-bottom operational modes. The diverted drilling fluid passing through the bearings is redirected into the bore of the mandrel via ports through the mandrel wall to rejoin the main flow to the drill bit, such that substantially all of the drilling fluid flows through the bit.

摘要： A device for detecting pressure and/or temperature changes in a fluid-channel and method thereof are disclosed. The device includes a main duct with an inlet and an outlet, a branch ductwork with a first branch end branching off the main duct downwards the inlet and with a second branch end discharging into the main duct upwards the outlet, and at least one dead-end channel with a first end that branches off the branch ductwork and a second closed end. The dead-end channel is adapted to trap a gas bubble within the dead-end channel when the device is primed or filled with a liquid fluid, wherein the gas bubble changes its size or position if a change in pressure or temperature occurs in the device.

摘要： A locking paddle handle assembly for closures has a housing with a paddle handle pivotally mounted therein, a latch which latches and unlatches the closure upon rotation of the paddle handle, and a exterior key lock with a movable member that shifts between locked and unlocked positions. A deadbolt lock selectively engages the closure frame in the locked position to positively retain the closure closed. The deadbolt lock is operably connected with the movable key lock member, such that movement of the latter between the latched and unlatched positions contemporaneously shifts the deadbolt lock between the locked and unlocked positions. A remotely operable controller is operably connected with the deadbolt lock to power shift the same between the locked and unlocked positions from a remote location.
