A roller for use in a developing unit of an image forming apparatus may include a non-conductive shaft member and a non-conductive member to surround at least a part of an outer periphery of the shaft member. The shaft member may include a cylindrical rolling part and a pair of support parts formed to project from both ends of the rolling part in a lengthwise direction. The rolling part of the shaft member may be arranged opposite a charge roller in a developing unit and may rotate in contact with the charge roller to absorb and remove foreign substances adhered to a surface of the charge roller.

A tree liner is formed from a composition of a sheet of brown coir to which a latex mixture is applied, preferably by spraying. The tree-liner may be inserted in a wire basket and used to wrap, cover and/or protect the roots of young trees and bushes during the lifting, preparation, packaging and shipping process from the nursery to the final user. The tree-liner comprises approximately 80% coir and 20% latex composition by weight. There is also provided a standalone plant container formed from a sheet of the same coir/latex composition. The composition may also be used for bedding, insulation and other various applications.

A method for fabricating a mixing device comprises the steps of: a) providing a grooved conveying plate; b) bonding recessed first and a second cover plates to respective surfaces of the conveying plate, thereby to define first and second sets of separated interdigitated channels and first and second distribution manifolds; and c) forming respective supply ports through surface(s) of the cover plates. Each port is disposed in fluid communication with a respective distribution manifold. A dispenser apparatus is formed by connecting a header having a first and a second passage formed therein to the mixing device so that the first and second passages in the header are respectively disposed in fluid communication with the first and second supply ports in the mixing device.

An elastic membrane is provided for use in a flow-control device comprising a housing with a seat of a predetermined shape and dimensions for the membrane such that when the membrane is mounted in the seat, the membrane is deflected by a pressure differential between its two opposite sides. The elastic membrane has a predetermined shape and dimensions matching the seat and is made of foamed elastomer with closed cells of predetermined cell density and morphology.
