Chemically modified unpyrolyzed Poaceae fibres having a length of less than 200 mm advantageously comprised between 2 and 100 mm, such as between 2 and 10 mm, said fibres having a water content of less than 40% by weight, and being treated with a treating aqueous dispersion comprising less than 1% by weight of surface treating mixture comprising at least a silanol terminated polydimethylsiloxane, as well as an amino coupling agent.

Poaceae fibres and building products

A roller intended to be in contact with toner particles is provided with a cured resin layer having homogeneously dispersed carbon black aggregates and having a thickness of less than 200 &#x3bc;m, whereby the carbon black aggregates have a weight average size lower than 30 &#x3bc;m, a DPB absorption of more than 110 ml/100 g, a BET-surface area greater than 250 m/g, and coated with an amino silane compound.

Roller for a printer, fax machine or copier

Sealing film having a substantially longitudinal central strip to be torn out between a first end and a second end, whereby the central strip has a substantially constant width and a substantially longitudinal central axis, and whereby an end of the central strip adjacent to one end selected from the first end and the second end has a width which varies from the substantially constant width of the central strip to an end width lower to the substantially constant width of central strip.

Sealing member for toner cartridge

A device for coating an element is described. The device is capable of bearing and using a swab impregnated with a coating composition and includes a mobile carriage for bearing the swab. The carriage is movable along a guiding path. The device further includes an element for pushing the swab towards the element to be coated so that a quantity of the composition released from the swab coats an element. The device also includes an element for distributing the composition, so that the coating is substantially uniform.

Device for coating an element and coating process

Sealing member formed by a sealing film with a substantially longitudinal portion to be torn out, wherein the sealing film is connected to a pulling strip made of a layer, with fibers extending in a direction forming an angle between &minus;60&deg; and &plus;60&deg; with respect to the tearing direction of the longitudinal portion to be torn out.

Composition for treating substrate and process of treatment

Sealing member for toner container having a tearable central strip and being associated with connecting elements ensuring the pressing of the lateral portions of a compressible cleaning element, with respect to the portion of the cleaning element intended for cleaning the torn central strip.

Process for coating a siliceous substrate with a silicon containing layer

The doctor blade consists of at least a substrate provided with an element having a face adapted for working with a magnetic roller, the element being made at least partly of an elastic material, wherein the face adapted for working with a magnetic roller has an abrasion resistance of less than 0.5 g (measured according to the method ASTM D4060).

Doctor blade, toner cartridge using such a doctor blade and copying process

Parts of toner cartridges are attached by means of hot-melt means, so that the reconditioning of the toner cartridge is facilitated. The sealing member comprises a sealing film with hot melt means.

Sealing member for toner assembly

Member for a printer, a fax machine, a copier or a toner cartridge, in which said member has a face in contact with toner particles, said face being provided with a top layer in contact with toner particles, said top layer comprising substantially spherical particles with a Mohs hardness of more than 3 or equal to 3 and an average particle size lower than 100 &mgr;m.

Component for a printer, fax machine, copier or the like

A process is presented for recycling a toner cartridge, including a used magnetic roller and a used doctor blade. The process requires: (1) removal of the doctor blade and magnetic roller from the cartridge; (2) treatment of the doctor blade to restore the shape of said doctor blade; (3) coating of the doctor blade and magnetic roller with an antistatic and anti abrasive coating; and (4) placement of the doctor blade and magnetic roller back into the cartridge. Additional processes involving reuse of other toner cartridge components are also described.

Process for recycling a toner cartridge

A siliceous substrate having a face which is at least partly provided with a water-repellent layer having a thickness of no greater than 5000 Angstroms, said layer being a layer of at least one fluoro aliphatic silane compound having at least one silicon atom chemically bound to the siliceous substrate and chemically bound to the silicon atom of another fluoro silane compound of the layer.

Siliceous substrate with a silane layer and its manufacture

The doctor blade consists of at least a substrate provided with an element having a face adapted for working with a magnetic roller, said element being made at least partly of an elastic material, wherein the face adapted for working with a magnetic roller has an electrical surface resistivity of less than 9.9 10,&OHgr; per square and wherein the element has thickness of at least 100 &mgr;m.

The device for coating an element with a swab impregnated with a coating composition includes a mobile carriage bearing the swab wherein the carriage is movable along a guiding path, a member for pushing the swab towards the element to be coated so that a quality of the composition released from the swab coats the element, and a member for varying the release of the composition so that the coating is substantially uniform.
