The invention relates to conductive heaters, and has its objective to provide a material that exhibits a uniform heating effect over the full area of the heater, relatively free from hot and cold spots, a further objective being to maintain the heater pliable. These objectives are met by a conductive material comprising finely divided carbon particles uniformly dispersed in an elastomeric carrier there being carbon particle levels of 20% to 75% by dry weight to carrier levels. Preferably, the carrier is an elastomeric polymer. A further aspect of the invention is a method of forming a compound for an electrically conductive heater comprising stirring fine carbon particles into a polymer base containing an anti-adsorption compound, to achieve carbon particles to polymer levels of 20% by dry weight to 75% by dry weight, and subjecting mixture to high speed stirring for a pre-determined period of time, with the maintenance of the mixture below a predetermined level, to grind the carbon particles to a predetermined final fineness.

A method, an apparatus and a system for providing secondary or backup Internet access are disclosed. The system includes a local network server having a primary router for directing data to/from a primary Internet backbone and a secondary router for directing data to/from a secondary Internet backbone. The primary router is connected to a primary local communications circuit employing a primary transmission medium. A primary point of presence is connected to the primary local communication circuit, and thereby provides primary Internet access via a primary Internet backbone. The secondary router is connected to a secondary local communications circuit employing a secondary transmission medium different than the primary transmission medium. A secondary point of presence is connected to the secondary local communication circuit, and thereby provides secondary Internet access via a secondary Internet backbone. The system employs control logic for detecting a failure to provide Internet access via the primary router, and for directing communication to the secondary router. A method and an apparatus for providing secondary Internet access are also disclosed.

A method of manufacturing flexible card-clothing for use in textile carding comprising the steps of producing a foamed polyvinylchloride compound having a density of between 0.6 and 1.00 grams per cubic centimeter; applying a sealing coat of a material which is compatible with the foamed compound to a fabric layer; applying a layer of the foamed p.v.c. onto the seaing coat to produce a finished foam layer of between 2 and 5 millimeters thickness on the fabric; heating the applied foamed layer to p.v.c. to cause the foamed layer to fuse; applying a surface layer of sealing material onto the exposed surface of the foamed layer to provide a smooth non-absorbent external surface, with the fabric, foamed p.v.c and surface layer together forming a composite foundation face, combining the foundation face with a foundation back to form a laminated foundation, and then inserting card-clothing wires into the foundation so that parts of the wires project from the surface layer.

A lighting fixture for filming motion pictures includes a lamp housing having a rear bezel and a front three-sided frame. A rear reflector slidably attaches to the rear of the lamp housing over the bezel. A snoot has a rear bezel slidably fit into the three-sided front frame on the lamp housing. The snoot has a front frame similar or identical to the front frame on the lamp housing, so that a second snoot can be slidably attached onto the first snoot. The frames form slots for receiving and holding gels. The lighting fixture may used as a simple open front reflective lighting fixture, or the snoots or gels may be added to achieve various lighting conditions.

Textile-finishing agents are provided by compounds of the formula(Rf).sub.m --A-- (X).sub.nwherein Rf represents a fluorocarbon chain, A represents a linking group, X represents a sulphonazide or azidoformate group and m and n are integers. The Rf group may be a linear or branched fluorocarbon chain containing 2 to 12 carbon atoms, and the linking group A may be a simple organic linking group or it may be a macromolecular linking group. The simple linking groups may have one or more fluorocarbon chains and one or more azido groups attached thereto, while the macromolecular linking groups may have a considerable number of fluorocarbon and/or azido groups attached thereto.

A foldable board is useful for developing, presenting to clients and storing key video and audio portions of proposed TV commercials. The board preferably has three panels joined together by a decorative backing or cover and foldable along vertical lines. Each panel has a front facing having two or more vertically spaced windows cut out in the shape of a TV screen and adjacent the window is a slot through which a sketch of a TV scene may be inserted. Below each window is space to attach a label bearing an audio statement corresponding to the video scene in the window. Behind the facing is a sheet of vinyl or other material and behind the vinyl is a stiffener of cardboard or the like. Each sketch is inserted through the appropriate slit and adheres to the vinyl by friction and tight fit. Scenes and labels may be changed as production of the commercial develops.
