Structure for stripping cotton bolls from cotton stalks comprising a rubber batt having a rounded head and a toed foot; said foot being formed so that it may be installed into a lipped channel strip for connection to a rotatable shaft. The rounded head of the batt provides a buffering contact area between the batt and a cotton stalk thereby preventing excessive chipping of bark from the cotton stalk during harvesting operations. This results in production of a more pure cotton product by minimizing a cotton stripper's collection of foreign matter together with the desired cotton bolls.

A fixed grip chairlift comprises a continuously moving conveyor for transporting the skiers to the loading point, where they are catched up by the chair which moves at a higher speed. The chair impact is thus reduced and the chairlift speed may be increased. The conveyor comprises an endless belt which passes around two drums, each drum being barrel like shaped to centralise the belt on the drums during running. The drum outer surface has holes to allow the snow transported by the belt towards the drum to escape.

A contaminant removal head is disposed on a holder which is movable along a printing cylinder. The contaminant removal head includes a timing belt having a plurality of contaminant removal blades disposed at a predetermined pitch along the timing belt. The timing belt is rotatably disposed on a pair of spaced-apart timing pulleys driven by a motor that intermittently rotates the timing belt. A control unit controls the motor to position one of the contaminant removal blades adjacent the printing cylinder to remove contaminants therefrom. After contaminants have been removed from the printing cylinder, the motor rotates the timing belt to position a portion of the timing belt between adjacent contaminant removal blades adjacent the printing cylinder.

A conveyor for transferring loose bulk material, such as fertilizer and the like, in a manner which minimizes the creation of airborne dust includes structure for movably supporting the material to be transferred, structure for automatically cleaning the movable support during movement of material thereon and for causing the structure for movably supporting the material to be transferred to move.

An abrasion resistant material is combined with a flow promoting material to provide a conveyance that is flow promoting and wear resistant. Holes formed in a UHMW conveyance allow a ceramic overlay to bond to itself creating a mechanical bond with the UHMW. In a first embodiment, a ceramic composite overlay is form fit to UHMW mixing paddle. The paddle has a tongue with holes therethrough. The ceramic overlay fills the holes creating a mechanical bond between the paddle and the ceramic composite. In another embodiment, a ceramic overlay is bonded to a steel insert received in a channel formed in the distal end of a mixing paddle.
