Abstract: A jig apparatus is used in extending a belt across a pair of pulleys of a variator for a transmission of a motor vehicle. The variator has the pair of pulleys, a groove width of each of which is variable, and a belt for driving the pulleys. A supporting bar and a supporting pipe hold the pulleys such that an axial line of rotation of each of the pulleys becomes parallel to each other. A groove width of at least one of the pulleys is pneumatically or mechanically widened. A sheave half of each of the pulleys is brought into a pulley groove of the other of the pulleys.

Abstract: Successive road elements of a road barrier, a partition or the like are turnable relative to one another by means of hinge elements connected to their facing walls. They can be transferred by a device having a substantially C-shaped hollow guiding element with opposite ends spaced from one another in a transverse direction, and a plurality of carts each having a substantially vertical shaft articulately connected with two successive road elements in the area of the two successive road elements, so that when the guiding element is longitudinally displaced, the carts are displaced inside the guiding element without engagement of the road elements with the guiding element, and the carts with the successive road elements are transferred from the area of one end to the area of the other end of the guiding element transversely.

Abstract: A bicycle chain derailleur is biased against the movement of a cable by a first spring that has enhanced biasing characteristics. In accordance with one embodiment of the present invention, the enhanced biasing characteristics are provided by the addition of a second spring element, where the second spring is an elastomer coating formed on coils of the first spring. In another embodiment a torsion spring is disposed in the chain derailleur which works in concert with the first spring to enhance the biasing characteristics. In yet another embodiment, both the elastomer coating and the torsion spring are employed.

Abstract: A belt of a variator is automatically assembled into a pair of pulleys. The pulleys are held by a pulley holding unit which has a pair of holding members for holding the pulleys such that axial lines of the pulleys become parallel to each other. The pulleys are arranged to be relatively moved such that a sheave half of each of the pulleys is brought into a groove of the other of the pulleys. A belt feeding unit feeds the belt. A belt assembly head pinches the belt to be fed from the belt feeding unit for extending it across the pair of pulleys. The belt assembly head has belt pinching devices and an arrangement for moving the belt pinching devices which pinch an intermediate portion of one side of the belt and an intermediate portion of the other side of the belt.

Abstract: A portable apparatus is provided for affixing a lacer assembly to one end of a belt. A lacer assembly is in the form of a plurality of paralleled metal lacing hooks each having a pin receiving loop, the lacing hooks each having opposed sharpened ends that are spaced to receive the end of a belt therebetween. The apparatus has a base that supports a backup anvil and moveable anvil that receives a lacer attached therebetween. The lacer attachment includes an elongated bolt extendable through the loop of each of the lacer hooks by which a lacer assembly is temporarily retained. A manually operatable jack is supported to the base and has a moveable portion that engages the moveable anvil. When one end of a belt is positioned between the sharpened ends of the lacer hooks positioned in the lacer attachment the jack can be actuated to force the lacer attachment jaws towards each other to deform the lacer hooks to attach them to the belt.

Abstract: A self-propelled and reversible compactor 10 includes a motor 12, a motor mounting plate 14, a tamper plate 16, a vibrator assembly 30, a driven pulley 38, a drive pulley 48, and a directional control arm 54. The vibrator assembly 30 is pivotally attached for selective pivotal positioning of a vibrator housing 36 of the vibrator assembly 30 at a first end 26 or a second end 28 of the compactor. The driven pulley 38 is mounted on a shaft 34 of the vibrator housing 36. The directional control arm 54 provides a manually operated control for providing the selective pivotal positioning of the vibrator housing 36. An endless flexible belt transmits the power from the drive pulley 48 to the driven pulley 38. Components mounted on the engaging end 58 of the directional control arm 54 engage one of the two tangential strands of a flexible endless belt 52 for pivotally displacing the vibrator housing 36 from the first end 26 to the second end.

Abstract: A belt tensioner for a twisted belt that tends to elongate during usage includes a tensioning pulley for operably engaging the twisted belt, a carrier for the pulley pivotally connected to a frame, a tensioning device for applying continuous force to the tensioning pulley carrier so as to tension the belt, and an unidirectional locking mechanism that allows the carrier to swing in only one direction and not in a reverse direction.

Abstract: The articulated pontoon floating bridge arrangement comprising plurality of pivotably interconnected pontoon modules. The actuation means installed inside of each module facilitate rapid folding and unfolding operation. Pontoon modules when unfolded in extended position provide articulated pontoon bridge arrangement used for vehicular traffic applications. When transported, the pontoon modules assembly is folded together in upstanding vertical juxtaposition and towed or transported rapidly and safely in a pontoon carrier to the operating site.

Abstract: A belt tensioner of the Zed type with a pivot-arm attached to an off-set cylindrical member supported by sleeve-type bushings with axially spaced-apart bearing surfaces disposed over a pivot where the bearing surfaces have an axial length that is sized for an average pressure contact. The tensioner may include a spring activated damping mechanism with a brake shoe having oppositely facing inside ramp surfaces which operate in such a manner to provide a normal force that is greater than a spring force applied to the brake shoe.

Abstract: An integrated chain tensioner having a tensioner arm that includes a first side, a second side, a first end, and a second end. The tensioner arm also includes a fluid reservoir defined by at least a portion of the first side, the second side, the first end, and the second end. Further, a pivot bore is disposed in the first end and a tensioner bore is disposed in the first side of the tensioner arm. A hydraulic tensioner is disposed in the tensioner bore such that the hydraulic tensioner is in communication with the reservoir.
