Disclosed herein is an apparatus for variable fluid damping. The apparatus comprises a mount. The apparatus also comprises a damper coupled to the mount to apply a damping force in response to movement of the mount. The apparatus further comprises an electrical element positioned to correspond to the damper. The apparatus additionally comprises a rheological fluid disposed in the damper. The rheological fluid changes viscosity in response to a change in an output of the electrical element to change the damping force of the damper. The apparatus also comprises a controller to provide input to the electrical element in response to a normal operating condition or an emergency operating condition.

An automatic tensioning apparatus is provided that includes a tensioning drive unit having: a longitudinally extending stationary base frame with a plurality of guides extending between a lower portion and an upper portion, and a plurality of rotatable feed wheels axially secured at the lower portion, as well as a translatable drive frame slidably coupled to the plurality of guides with a drive assembly coupled to the drive frame, the drive assembly including a drive motor and a tensile member interface for engaging and rotationally translating a tensile member. The tensioning drive unit further including a plurality of drive frame actuators actuatable to move the drive frame between a bottom frame position and a top frame position, as well as a sensor for at least indirectly sensing the position of the drive frame along a longitudinal base frame axis.

A rotating painting apparatus includes a plurality of painting stations rotatably mounted to a base plate and each station having 2, 3, 4, or more faces on which to apply paint. A painting station includes a drive shaft rotatably coupled to the base plate. Rotation of the drive shaft causes the painting station to swivel, i.e., to rotate. The stretched frame member includes upstanding side support members extending from the bottom wall and about which a length of canvas may be stretched to form a painting station having two faces (front and rear), three faces (triangular), or four faces (cube), and so on. A chain drive operated by a drive motor enables all of the frame assemblies to be rotated together. The apparatus may include a motion sensor operable to actuate the motor and drive shaft to cause rotation when motion is detected.

To provide a chain guide that can improve transportability and assembly operation efficiency, while also ensuring stable running of a timing chain and enhancing durability, with a simple structure. The chain guide has a guide shoe that slidably guides a chain, and a chain guide body that supports the guide shoe. A compression limiter having an attachment hole through which a mounting bolt for attaching the chain guide to an attachment target member passes is fitted in a fixing through hole extending through the chain guide body in a width direction thereof. A compression limiter holding mechanism is provided either to the compression limiter or to a hole rim part including the fixing through hole of the chain guide body in order to hold the compression limiter.

An object of the present invention is to provide a tensioner lever that allows for reduction of the number of components and the weight, while being able to prevent vibration and noise during the running of the chain. The tensioner lever according to the present invention is configured such that a lever body rotatably supported on an attachment surface is urged to rotate toward the chain by the resilient force of a coil spring. The coil spring includes a pressing arm extending from one end of a helical part and contacting the lever body, and a support arm extending from another end of the helical part and supported by the attachment surface. The lever body includes an engagement portion configured to allow the support arm of the coil spring to be hooked thereon by resilient deformation, and to removably engage therewith by rebound resilience of the coil spring.
