Sustained over-tensioning of a power transmission device, such as a chain drive in an internal combustion engine, is prevented by overriding a tensioner ratchet mechanism to permit retraction of a tensioner. Tooth angle of the ratchet mechanism and pawl spring rate and preload are selected so that a sufficient axial force generated by chain/belt tension will produce a transverse force that overrides a biasing force acting on a pawl engaging a rack of the ratchet mechanism to retract a tensioning piston against hydraulic pressure and spring pressure by at least one tooth to reduce the sustained tensioning force applied to the chain/belt, while not adversely affecting the rack extension function. The tooth geometry of the pawl and/or rack of the ratcheting mechanism may have an angle chosen to be slightly less than the self-locking friction angle to permit retraction.

A modular welding wire feed drive for use in a welding system. The welding wire feed drive is designed to be detachably connected to the welding wire feed system of the welding system. The welding wire feed drive includes a drive housing designed to be detachably connectable to the welding wire feed system, a wire contact arrangement designed to controllably feed welding wire through the welding wire feed drive, and a drive motor that is connected to or interconnected to the wire contact arrangement to at least partially drive the wire contact arrangement.

A method and apparatus for monitoring a predetermined condition of a medium by; transmitting acoustical waves through the medium, continuously measuring changes in the transit time of the acoustical waves resulting from changes in the monitored condition; and utilizing the changes in transit time to provide a continuous measurement of the changes in the monitored condition. The acoustical waves are bending waves wherein cross-sections of the medium have a rotational movement orthogonally to the axis of propagation of the waves through the acoustical channel. Several examples of such method and apparatus are described, including a highly sensitive pressure sensor for sensing changes in pressure applied to a displaceable membrane, and a highly-sensitive vibration sensor for sensing earth or other vibrations.

The bioabsorbable band system includes a needle system and a bioabsorbable band including a bioabsorbable locking member. The bioabsorbable band includes a length having an at least partially oriented structure. The bioabsorbable band further includes a locking mechanism with a locking member. Also a method for producing the bioabsorbable band.

The invention discloses a tensile force detecting device for a conveyer belt. The tensile force detecting device comprises a chassis, a pipe, a spring, a pulley, a connecting block and a pressure sensor, wherein the chassis is hollowed and is arranged between the upper side and the lower side of the conveyer belt; the pipe is connected with the chassis, is hollowed and is arranged along a vertical direction; the spring is placed in the pipe; the pulley is arranged at a first end of the spring through a pulley support; a rotating shaft of the pulley is arranged on the pulley support; the pulley is held out against the inner surface of the conveyer belt which moves towards the lower side; the connecting block is arranged at a second end of the spring; the connecting block is placed in the chassis; the pressure sensor is placed in the chassis and is in contact with the connecting block; and the pressure applied by the connecting block to the pressure sensor can be detected by the pressure sensor. According to the tensile force detecting device for the conveyer belt, the real-time tensile force of the conveyer belt is detected through the spring and the pulley; the tensile force is collected from the lower side of the conveyer belt so as to remove the interference caused by the materials borne by the conveyer belt; and the spring ensures that the pulley can be clung to the conveyer belt all the time, so that accurate tensile force can be acquired.

A standard for supporting a game net above a playing surface is provided with an internal net tensioning system which allows the standard to be stored beneath the playing surface. A plurality of pre-set height stops are provided along the length of the standard to allow the net to be set at one of several different heights to accommodate the playing of different games by different playing abilities. Power cylinder mechanics permits the automatic raising and lowering of the standard with respect to the playing surface. A quick attachment system is provided for quickly and easily engaging and disengaging the net from the standard.

An electric power steering apparatus comprises a speed reducing mechanism for decelerating the rotation of a rotatable shaft in an electric motor and a converting mechanism for converting the output rotation of the speed reducing mechanism into the axial movement of a steering shaft extending toward the right and left sides of a vehicle. The speed reducing mechanism comprises an input pulley driven by the electric motor, an output pulley arranged with the steering shaft enclosed thereby, a belt for connecting the input pulley and the output pulley to each other, and means for adjusting the tension of the belt.

A second tether member is made of a long cloth member. Its rear end is fixed to a specified lower-side position of a fifth pillar which is located below the middle portion of this pillar in the vertical direction (i.e., at the position which is away from the top end of the fifth pillar by a distance of about 100 mm or greater) via a fixing pin. Its front end is fixed to a body portion of a curtain member via a seam portion. Accordingly, there can be provided the interior structure of a vehicle equipped with a curtain airbag which can properly form the tension line at the curtain member.
