Abstract: A tensioner for a chain or similar power transmission medium comprises a spring-biased plunger having annular rack teeth with gradually sloping forward surfaces and steeper rearward surfaces. The teeth are engaged by radially movable balls received in inclined grooves in an axially movable annular ball seat disposed in an annular groove formed in the wall of a plunger-accommodating hole in a tensioner housing. The bottoms of the inclined grooves face a steep rearward surface of a rack tooth, and the annular ball seat is axially movable in the annular groove and biased in the plunger protruding direction by a spring that exerts a biasing force greater than the biasing force exerted on the plunger. The balls and the movable annular ball seat block retraction of the plunger on engine start-up, but permit retraction when excessive force is imparted to the plunger while the plunger is in a protruding condition.

The hoist attachment includes controls operating the primary winch, boom, and hydraulic support legs. The base frame also includes a plug to which a remote may be attached for remote operation, the plug being connected to an electrical power source.

Abstract: Continuously variable speed drive (CVT) have improved performance due to use of two groups of flyweight cams, each group being mounted on separate rotational members of a centrifugal clutch. One set of flyweight cams provides force to close the sheaves through the entire movement of the shift, whereas the other set of flyweight cams provides force only through an initial portion of the shift and then signs off. This provides a two stage shift behavior for the CVT that enhances power transfer to the driven pulley.

Abstract: A reversible seat belt tensioner includes an electric motor (2), a belt shaft (1) drivable in the belt winding direction by the electric motor (2) via a drive wheel (10), and a drive shaft (9) transmitting the rotational movement of the electric motor (2) to the drive wheel (10). The drive shaft (9) is connected to at least one of the drive wheel (10) and the electric motor (2) via a helical gear unit. The use of a helical gear unit provides the advantage that the rotational axes of the meshing components can be arranged at angles other than 90 degrees with respect to each other because the components in the helical gear units only come into punctiform contact.

Abstract: A method and an installation are used for inspecting a surface of a coiled metal strip, wherein the coil to be inspected is unwound along a moving plane so as to cause at least part of the strip to move to a position for inspecting the surfaces. Accordingly, the method consists in moving the part of the strip to be inspected along a substantially vertical inspection plane, between an unwinding device and a winding device arranged on two vertically spaced apart levels on either side of an intermediate inspection level. Thus, the inspection is visually performed on both surfaces of the strip by an operator moving about on a floor at the intermediate inspection level.
