Abstract: A powder-rubbing apparatus comprises: a rotatable rubbing roll having a rotational axis; a substrate path; an oscillating mechanism for oscillating the rotatable rubbing roll along the rotational axis; and a powder coating die comprising an inlet port in fluid communication with an outlet port disposed adjacent to the substrate path. The substrate frictionally contacts the rotatable rubbing roll within a rubbing zone. A dispenser for dispensing gas-borne powder is in fluid communication with the inlet port of the powder coating die. The dispenser is aligned such that at least a portion of a gas-borne powder dispensed from the powder coating die is deposited directly onto at least one of the rotatable rubbing roll or the substrate and conveyed into the rubbing zone. A method of using the powder-rubbing apparatus and a powder-rubbed web preparable thereby are also disclosed.

Abstract: A device includes a connected array of cells formed in a stack of flexible sheets. Each pair of adjacent sheets in the stack includes a first sheet and a second sheet bonded together at multiple bond locations. Each sheet has an electrically conductive layer disposed on an electrically non-conductive layer, the conductive layer comprising an electrically conductive non-metal material. Each pair of adjacent sheets in the stack is arranged so that the non-conductive layer of each first sheet is between the conductive layers of the first and second sheets. The cells of the array reversibly transition between an open state and a closed state in response to an electric potential having a magnitude greater than a threshold value applied between the conductive layers of the first and second sheets.

Abstract: Multi-layer cover tape constructions include a polymeric substrate with a low adhesion backsize coating layer on one surface and an adhesive layer on the other surface, with a conductive film construction adhered to a portion of the adhesive layer such that portions of the adhesive remain exposed. The conductive film construction includes a polymeric substrate with an exposed layer of abrasion-resistant, electrically conductive nano-scale graphite coated by buff coating. Other multi-layer cover tape constructions include a polymeric substrate with a low adhesion backsize coating layer on one surface, and an exposed layer of abrasion-resistant, electrically conductive nano-scale graphite particles coated on the other surface. Stripes of adhesive are present on a portion of the electrically conductive coating such that portions of the electrically conductive coating remain exposed between the adhesive stripes. Carrier tapes include a plurality of indented segments for accommodating electronic components and are releasably sealed by a cover tape.
