Abstract: A method of making a high-temperature and fire-resistant fabric is described in which staple carbon fiber yarns are woven into a unified multi-layer woven fabric. The warp ends and filling picks of the unified multi-layer woven structure are positioned such that they prevent penetration of fire flames, welding sparks and molten metal spatter from penetrating through the unified multi-layer fabric.

Abstract: A composite pad is made of two layers joined together at their interface. The top layer of the composite pad, which has a smooth surface has a dense and firm fine denier fibrous structure. The bottom layer of the composite pad has a lighter and softer coarser denier fibrous structure in order to be able to have a large fluid holding capacity. A method of manufacturing the composite stamp pad is described.

Abstract: The present invention teaches formulations, apparatus and a method of applying high thixotropic index polymer thick-film resistive pastes for making polymer thick-film resistors with improved tolerances by providing a squeegee with a blade tilted at an angle of 10° to 85° to the surface of the printed circuit board thus causing a fluid rotational motion within the bead of the polymer thick-film resistive paste as the squeegee blade moves relative to the printed circuit board. This rotational motion increases the shear strain rate experienced by the paste within the bead and results in a more effective filling of the resistor-shaped cavity without including air bubbles, experiencing elastic recovery of the paste and, without surface fractures of the paste.
Abstract: A composite stamp pad is made of two layers joined together at their interface. The top layer of the composite stamp pad, which contacts the raised points side of the stamp, has a dense and firm fine denier fibrous structure in order to be able to transfer ink to the raised points of the stamp with high precision and without depositing ink into the recessed areas located between the raised points of the stamp. The bottom layer of the composite stamp pad has a lighter and softer coarser denier fibrous structure in order to be able to have a large ink holding capacity. A method of manufacturing the composite stamp pad is described.
