Abstract: An adjustable wrappage film feeding device includes a chassis having end plates rotatably supporting a driving shaft therebetween. The driving shaft is driven by a motor via a worm—worm gear transmission. Two first bevel gears are mounted on the driving shaft to be rotatable in unison with the driving shaft while being allowed to axially move with respect to the driving shaft. A screw rod is rotatably supported by the end plates and threadingly engages two movable carriages that are spaced from each other a distance. By rotating the screw rod, the carriages are driven toward/away from each other and thus changing the distance therebetween. Each carriage rotatably carries a roller adapted to drivingly engage and convey a film in a predetermined direction toward an article to be packaged. Each roller is coupled to a corresponding one of the first bevel gears by a second bevel gear that mates the corresponding first bevel gear.

Abstract: A slack puller has symmetrical sheave assemblies on each side of a cable path. The sheave assemblies each include a driven sheave mounted on an arm. When the sheaves are engaged with the cable by an actuator, tension in the cable pulls the sheaves in a way which tends to increase the compressional forces exerted by the sheaves on the cable. The self actuating nature of the slack puller allows compressional forces on the cable to be kept small until the cable comes under tension. The sheaves are driven by positive displacement hydraulic motors connected in series with a hydraulic pump. This permits the sheaves to turn quickly when the cable is not under tension and slows the sheaves as tension in the cable increases. The slack puller operates more quickly and causes less cable damage than conventional slack pullers. The slack puller has particular application in skyline logging operations where its compact size is an additional advantage.

Abstract: An automatic photographic developing machine allows a rack to be pushed up only if a feed mechanism of such rack is put under excessive load, and is made of fewer parts and is simple in structure. The rack has a feed mechanism for feeding photosensitive material and is inserted in a treating tank. The rack has an input shaft at its upper portion. The input shaft carries a helical gear in mesh with a worm of a drive shaft. A resilient piece made of synthetic resin is supported on a presser holder slidable in the axial direction of the drive shaft. An end of the resilient member is located opposite the end of the input shaft to prevent the rack from being pushed up. If the force urging the rack upward exceeds the resilience of the resilient piece due to an excessive load applied to the feed mechanism, the resilient piece is resiliently deformed by the input shaft. The rack is thus pushed up, and the helical gear is disengaged from the worm.
