Title: Method and apparatus for enhanced audio/video services with watermarks and associated data
Inventor: HOLLAR MARK A
IPC: H04N5/775
Filed: 2000-02-25
Abstract: Method and apparatus for controlled copying of an audio or video signal transmitted over a cable television or direct satellite broadcast system or the Internet. Copyrighted (or other) audio or video material is protected from unwanted copying (recording) by the combination of a watermark embedded in the audio or video signal at the head end together with additional copy protection data inserted in the audio or video signal, either a ticket or a second watermark. Video line (21) in the vertical blanking interval for (NTSC TV) is used to hold the ticket (cryptographic counter). An audio or video watermark is embedded in the active portion of the audio or video signal. Only if the consumer is willing to pay a fee is the video signal with both the watermark and the ticket transmitted to his recording device which then matches the watermark to a mathematical function of the ticket, and only if they match is recording permitted. Alternatively, this consumer control may operate on a second watermark in the audio or video. The corresponding playback device outputs an audio or video signal which does not have the ticket and hence no further copying is permitted. This enables a single copy to be made upon payment.

Title: Binder resin and synergist composition including a parting agent and process of making lignocellulosic articles
Inventor: WILSON JOE C
IPC: C08G18/64
Filed: 2001-11-23
Abstract: A method for preparing compression molded or pressed lignocellulosic articles is disclosed. The method involves forming a binder resin by combining a polyisocyanate component with a parting agent and preferably a synergist. The parting agent is the reaction product of an isocyanate compound and an isocyanate-reactive compound of the general structure R-(ao)n-Y where: R is a hydrophobic group containing alkyl, alkaryl, polyaryl, or siloxane moieties; (ao) is an alkylene oxide or mixture of alkylene oxides; n is from 1 to 25; and Y represents a monofunctional isocyanate-reactive group. A resinated lignocellulosic mixture is formed by combining the binder resin with lignocellulosic particles. Then a compression molded or pressed lignocellulosic article is formed by compressing the resinated lignocellulosic mixture at an elevated temperature and under pressure. It is particularly preferred that the binder resin further include a synergist of either a C1-4 N-alkylpyrrolidone, gamma-butyrolactone, or a mixtures of them. The most preferred synergist is N-methyl-2-pyrrolidine.

The system comprises at least an upper and a lower elongate rail. Each rail has a hollow interior defining a substantially I-shaped cross-section including at least a first slot and a second slot. A  plurality of pickets are transversely slidable through openings in an upper surface of the rails and a channel in a lower surface. The pickets each have at least a first notch or indentation near a first end and a second notch or indentation near a second end. The distance from the first end to the first notch or indentation is preferably shorter than the distance from the second end to the second notch or indentation. An elongate retaining rod slidable within at least one rail cooperates with a notch or indentation on each picket to secure the picket to the rail. Rather than the retaining rod, spring clips, threaded fasteners or the like may cooperate with a hole in each picket to secure the picket to the rail. The pickets are invertible, such that they extend a distance x or a distance y above the upper rail depending upon whether the first or second notch or indentation or hole engages the retaining rod or other fastening member. Finials and decorative inserts may be secured to the fence to provide more aesthetic styles. Further, the upper rail is invertible, wherein a smooth cap may be secured to the upwardly facing surface of the upper rail, providing the fence with a smooth upper end having no protruding pickets.
