Abstract: A lift has two tines that project forward and are movable up-and-down to raise and lower pallets and skids. Two outriggers are pivotal between a stored position and a deployed position, and the outriggers project forward in the deployed position to stabilize the lift when the tines are elevated.

An opening is formed in the region between the upper and lower link webs, which has, in plan view, a substantially trapezoidal shape with sides of substantially equal lengths and an upper side and lower side of different lengths. The upper side is assigned to the upper link web and the lower side to the lower link web.

The components downstream of the rotating conduit rotate at a different speed than components upstream of the rotating conduit.

Abstract: A cord winding device for a window covering includes a casing, a reel rotatably mounted on the casing, a torsion spring biased between the casing and the reel, a limit ring secured on the casing and abutting the reel to limit the reel between the casing and the limit ring, and a pull cord attached a bottom of the casing. Thus, the lift cord of the window covering is wound around and stored in the reel of the cord winding device so that the lift cord is rolled up to a higher position to prevent the children from being tangled with the lift cord so as to protect the safety of the children.

Abstract: A synthetic fiber rope can be used to the limit of failure by setting a sensitivity of detection of the state of wear of the rope. Strands of the rope have indicator fibers or indicator yarn that have a high probability of losing electrical conductivity and thereby indicate a worn cable. The indicator yarn consists of indicator fibers and of synthetic fibers, the indicator yarn fibers being inferior in relation to stress than the synthetic fibers of the strands.

Abstract: In an oil buffer for an elevator, at least one cylindrical intermediate plunger is inserted into a base cylinder. An upper-stage plunger is inserted into the intermediate plunger. An orifice is provided in a bottom surface portion of the upper-stage plunger. A pin rod is provided upright in the base cylinder. The pin rod is inserted into the orifice in a middle of a stroke of the upper-stage plunger. A return spring causes the intermediate plunger and the upper-stage plunger to return to positions in an unloaded state.

Abstract: A method and an arrangement are provided for fixing the compensating ropes of an elevator to an elevator car or to a counterweight, which elevator includes at least a hoisting machine and hoisting roping, suspended by which the elevator car as well as the counterweight are arranged to travel, and between which elevator car and counterweight compensating ropes are fixed such that the first ends of the compensating ropes are fixed to the counterweight, from where the compensating ropes are led downwards to pass below a compensating pulley, after which upwards to the elevator car, where the second ends of the compensating ropes are fixed by wedge housings in connection with the elevator car. When fixing the ends of the compensating ropes in connection with the elevator car or the counterweight, the wedge housings are turned into an inclined attitude before disposing the ends of the compensating ropes in the wedge housings.

Abstract: A system and method for lubricating components where the lubricant is applied in mist form within a substantially enclosed cavity. The cavity contains a draining aperture which collects excess lubricant for subsequent re-use by the system. The cavity is defined by a spray head that includes a base having attached thereto a cover plate with an opening adapted to receive therethrough a component to be lubricated. The cavity and lubrication chamber prevents the escape of excess lubricant. The collection and reuse of excess lubricant provides a closed loop system that reduces lubricant waste.

In a specific example, the links have a clevis-like portion and an arcuate segment defining a drive-surface with a characteristic outer diameter, and the arcuate segment of the first link pivotally engages the clevis-like portion of the second link to form the pinned connection. The arcuate segment extends circumferentially about only a portion of the pivot axis by an angle. The drive-train sprockets have a body having a root diameter corresponding to at least a characteristic outer diameter of the arcuate segment and the angle by which each arcuate segment extends circumferentially about the corresponding pivot axis.
