Torsional damper having variable bypass clutch with centrifugal release mechanism

A torsional damper (10) rotatably supported for translating torque between a prime mover and the input of a transmission including a torque input member (12) that is operatively connected for rotation with the power take-off of a prime mover, an output member (14) operatively connected for rotation with the input to a transmission and a plurality of damping elements (16) interposed between the input member and the output member. The damping members (16) act to translate torque between the input and output members and to dampen torsional forces generated between the prime mover and the transmission. A bypass clutch (40) acts to translate torque directly between the input and output members thereby providing a path for partial torque translation that bypasses the damping elements at low rotational speeds of the input and output members. In addition, the torsional damper (10) includes a clutch release mechanism (42) that is responsive to centrifugal forces acting on the torsional damper to disengage the bypass clutch (40) to reduce the torque translated directly between the input and output members at high rotational speeds.

A support for a pad computer and the like includes a body support strap which may be placed around the neck or shoulders of a user, and a body propping unit that positions a computer outwardly from the torso of the user. The body support strap connects to the body propping member preferably at a location proximately aligned with the center of gravity of the combined mass of the computer and computer support when the body popping member is deployed in its stand-off position. In a preferred variant the body propping member is a U-shaped strut assembly with two arms joined by a bridge. The body support strap connects to the arms. The arms are hinged at the sides of the computer. The bridge may be swung from an in-use orientation spacing the computer outwardly from a user, to a parked position wherein the bridge lies adjacent to an opposite transverse edge of the computer in the plane of the computer.

Reducing effects of magnetic and electromagnetic fields on an implant's magnet and/or electronics

An implantable magnet that can freely turn in response to an external magnetic field, thus avoiding torque and demagnetization on the implantable magnet. The implantable magnet can be combined with an electric switching function depending on the orientation of an external magnetic field, thus protecting an implanted coil and / or implant electronics against induction of over-voltage or performing an electric switching function for other various purposes. The magnetic switch may further include, for example, a first switching contact and a second switching contact. A magnetically soft body that includes an electrically conductive surface is shiftable between a first position where the body is in simultaneous contact with the first and second switching contacts, and a second position where the body is out of contact with at least one of the first and second switching contacts. The body and the implantable magnet are positioned such that the body is shifted to one of the first position and the second position as a function of the external magnetic field resulting in a magnetic force between the magnet and the magnetically soft body.

Earth boring tool

InactiveUS20060237234A1Without adversely affecting cutter performance and drilling rateAvoid excessive wearDrill bitsBorehole drivesReamerDrill bit
An earth boring tool includes two coaxially-aligned, positive displacement motors. One motor turns a pilot bit and the other turns a reamer concentric with the pilot bit. The central bit bores the center of the hole and the reamer enlarges it. The central bit is rotated relatively faster, while rotation of the larger diameter reamer is relatively slow. The tool can thus be used to bore larger diameter holes without slowing drilling rates or adversely affecting performance of the cutter elements due to higher tangential velocities.

Control device and control method for vehicle

InactiveUS20090227409A1Reduce torqueSuppresses the increase in rotational speedHybrid vehiclesElectrical controlAutomatic transmissionEngineering
During downshifting, a control for restricting an output of an engine to constantly maintain electric power balance between a first electric motor and a second electric motor or a control for suppressing a rate of increase in engine rotational speed by a control on the engine, such as ignition timing retardation control or fuel injection amount reduction control, is executed to thereby allow torque of the second electric motor to be reduced during downshifting. In addition, the engine rotational speed is decreased before downshifting, and, after the engine rotational speed is decreased to a rotational speed at which a protection control is not activated, an automatic transmission downshifts. With the above control, it is possible to suppress an increase in rotational speed of the second electric motor during downshifting. Thus, shift shock may be suppressed, and the friction material of the frictional engagement element may be protected.

System and method for generating power

A system and method for generating power includes a motor assembly, an inertia-assisted, torque-enhanced gearbox, including a flywheel assembly and a clutch assembly, and a generator assembly. The motor assembly is used to drive the flywheel assembly up to the generator's designed operating speed. When the flywheel assembly reaches the generator operating speed, the clutch assembly engages and connects the flywheel assembly to the generator assembly. When the flywheel assembly is connected to the generator assembly, it supplies the generator with the starting torque required to start the generator. The motor assembly then supplies the torque necessary to operate the flywheel assembly and the generator assembly at the generator's designed operating speed. When the generator encounters peak loads, the flywheel assembly also supplies peak load torques to the generator assembly. The generator assembly is operable to supply power to a load connected to the generator assembly.

Low torque hydrodynamic lip geometry for bi-directional rotation seals

A hydrodynamically lubricating geometry for the generally circular dynamic sealing lip of rotary seals that are employed to partition a lubricant from an environment. The dynamic sealing lip is provided for establishing compressed sealing engagement with a relatively rotatable surface, and for wedging a film of lubricating fluid into the interface between the dynamic sealing lip and the relatively rotatable surface in response to relative rotation that may occur in the clockwise or the counter-clockwise direction. A wave form incorporating an elongated dimple provides the gradual convergence, efficient impingement angle, and gradual interfacial contact pressure rise that are conducive to efficient hydrodynamic wedging. Skewed elevated contact pressure zones produced by compression edge effects provide for controlled lubricant movement within the dynamic sealing interface between the seal and the relatively rotatable surface, producing enhanced lubrication and low running torque.
