Abstract: An apparatus for automatically cleaning the clips on a web processing apparatus is described. The apparatus includes a scraper for scraping the web supporting surface of the clips on the web transporting machine, and also desirably includes a clip opener, for facilitating opening of the clip to enable the scraper to easily access the clip web support surface. The scraper is desirably supported in a manner that enables it to move upwards and downwards relative to the web supporting surface of the clips, to account for variations in clip height and positioning. The clip cleaner can be readily applied to existing web processing apparatus, such as tenter frames, and desirably can be selectively moved from an operative position to an inoperative position.

Abstract: The present invention concerns a conveying device with an endless conveyor belt, which has catches extending essentially transverse to the conveying direction. In order to further develop a previously known conveying device so that small bulk articles, which tend to stick, are reliably removed from the conveying device at an end point of the conveying device, which cannot be reached satisfactorily with the known devices for stripping, it is proposed that the catches be deepened trough-like or elevated ridge-like modifications of the conveying surface in comparison with the conveying plane, and that the catches can be completely swept by means of at least one stripper lying elastically against the conveying surface.

The apparatus comprises a platform frictionally engaging a plurality of the rollers such that the apparatus is conveyed along the roller conveyor by the rotation of the rollers, and a first cleaning element secured to the platform, wherein the first cleaning element engages a portion of the surface of the rollers as the apparatus is conveyed along the roller conveyor.

Abstract: The disclosed conveyor-belt cleaning assembly includes a ribbed cleaning roller that is restrained by a blocking device against moving closer to the belt than an operating position at which the ribs of the cleaning roller sweep at high speed along or close to the belt, while spring bias acting on the cleaning roller firmly but yieldably biases the cleaning roller toward the blocking device. The spring bias and the blocking device are adjustable independently of each other so that the operating position can be adjusted to compensate for wear of the ribs while the spring bias remains unchanged. The cleaning roller is supported by composite spherical/rotary bearings that allow the roller to tilt. A hole in a frame plate accommodates removal and insertion of the cleaning roller lengthwise without disassembling the frame plate when the cleaning roller is to be replaced.

Abstract: A screw conveyor for tacky media has members such as chains disposed in rest positions extending into the trough laterally of the screw axis. These members are engaged and deflected by the screw blade as it progresses along said axis. The members are subject to a restoring moment, such as the force of gravity, tending to forcefully restore the members to the rest position from the deflected positions so that the media is forcefully impacted by the members and adherent media is dislodged from the blade and agglomerates are disintegrated.

Abstract: A water based dredge includes a grizzly with a sieve and a pair of bi-directional rakes. The rakes translate relative to the stationary sieve to slide waste or recoverable material off of the grid and onto a refuse barge or material processing apparatus, respectively. A grab deposits dredge material onto the sieve and an operator determines whether the material includes waste such as clay or the like or recoverable material such as rocks, dirt, or sand. If the operator determines that the dredge material is waste, the rakes will be actuated for movement from a first direction to thereby push the waste off of the grizzly and onto a refuse barge. If the operator determines that the dredge material includes recoverable material, the rakes will be operated in a second direction so the recoverable material is slid from the grizzly and into a crusher or other appropriate processing apparatus.

During the reciprocation of the cleaning carriage the wiper blade wipingly moves along the glass lining. The excess cleaning liquid and the cleaning liquid which accumulates during the wiping of the glass lining is received and drained by a lower one of guide rails at which the cleaning carriage is guided.

Abstract: Chairlift or gondola lift with a carriage supporting a gondola or a chair and having a detachable grip for coupling on a continuously moving cable. In the terminals the carriage is uncoupled from the cable and it runs on a transfer rail. This transfer rail is equipped with friction drive wheels disposed along the carriage travel path for engaging the friction face of a running plate rigidly secured to the carriage so as to brake, accelerate or drive the carriage on the rail. During the night or bad weather periods a cover plate covers the friction face of the carriages disposed on the line and this cover plate is raised away in the terminals to clear the friction face. For removing the snow or ice which covers the friction face and hinders the correct friction drive of the carriage a brushing or rubbing device may be disposed along the carriage travel path so as to brush the friction face.
