Abstract: Une installation d'enregistrement vidéo prévient toute copie analogique et numérique d'un programme protégé contre les copies. Cette installation prévoit en entrée et en sortie des signaux vidéo analogiques et numériques. A l'entrée analogique, un détecteur (26) détecte une protection anticopie classique dans le signal d'entrée vidéo analogique et interdit alors l'enregistrement de ce dernier. A l'entrée numérique, un premier détecteur (20) détecte une signature de droit d'auteur dans le programme et interdit alors l'enregistrement de ce dernier. Un magnétoscope, un lecteur (10, 100) ou un décodeur de table spécialement adapté protège un programme vidéo doté d'une signature de droit d'auteur contre la copie. La signature est placée dans un site déterminé du signal vidéo à protéger. Le magnétoscope, le lecteur (10, 100) ou le décodeur de table, lors de la détection de la signature du droit d'auteur, au point d'entrée ou en lecture, modifie le signal vidéo de sortie normalisé (NTSC) par un processus de protection anticopie classique, et le signal de sortie numérique avec une nouvelle signature de droit d'auteur. Le signal numérique d'entrée peut présenter un brouillage complétant la signature de protection anticopie. De plus, on peut ajouter une signature d'authentification à ce signal vidéo numérique pour qu'elle soit détectée comme faisant partie du processus de protection anticopie. Pour utiliser cette protection, un téléviseur comporte un système de protection anticopie et de décryptage.

IPC: B65D65/22
Filed: 1997-02-11
Abstract: A protective cover for disposition over the crown of a single broccoli plant or the crown of a "bunch" (two or more of such plants) in order to maintain the freshness of the broccoli, potentially  increase  shelf  life  and  to protect  against contamination.  The protective cover comprises a relatively thin cover  film which  is  sized and shaped to  form an  internal compartment  for  receiving the  crowns  of  the broccoli.

Title: Process for separating enantiomers from a racemic mixture
Inventor: A CAMPO COR PETER MATHILDE GER
IPC: B01D61/24
Filed: 1995-10-16
Abstract: Proposed is a process for separating enantiomers from a racemic mixture by countercurrent extraction using at least two substances, one of them a liquid in which the racemic mixture to be separated is present, the other containing a chiral adjuvant which is combined with or part of a gel forming substance in the form of discrete particles in a liquid separated from the countercurrently flowing liquid containing the racemate to be separated by a microporous membrane having a pore size such that the pores can no longer be penetrated by the gel forming particles separated on conclusion of the extraction, followed by the setting free therefrom of one of the enantiomers under the influence of a stimulus, after which the particles are re-incorporated into the extracting process if so desired. During the extraction process the gel forming material preferably is in the swollen state, taking the form of discrete particles, and flows through a microporous membrane preferably made of polypropylene.

Title: Retainer for reel toothbar bearing
Inventor: KELLER MELVIN WILLIAM
IPC: A01D57/02
Filed: 1997-05-15
Abstract: A bearing or bushing retainer comprises two identical, separate segments which are generally c-shaped so as to permit the segments to each be removed from a cylindrical split plastic bearing mounted on a reel toothbar once bolts holding the two segments together are released and the segments moved axially relative to each other so as to disengage respective axially extending tabs of the segments from gaps defined between opposite ends of the segments. The segments have a relatively heavy cross section and are made of sintered powdered metal of relatively high carbon content, and are heat treated thereby resulting in a part having a long wear life and having a natural lubricity resulting in the extension of the wear lives of the retainer and of the bearing retained thereby.

Title: Dynamic mechanically switched damping system and method for damping power oscillations using the same
Inventor: KHAN AFTAB H
IPC: H02J3/24
Filed: 1996-01-29
Abstract: A dynamic mechanically-switched damping (DMSD) system is described which utilizes one or more mechanical switches and appropriate controls to switch series or shunt reactive impedances (14) in order to provide power oscillation damping in power systems. The DMSD system provides a controller (16) which can be configured based on the number of mechanical switches in the DMSD system, the type of reactive impedances interfaced to the power system by each switch and the magnitude of each of the reactive impedance. The DMSD system monitors parameters of the power system (17, 18) and the controller generates a modulation signal based on the monitored parameters. The modulation signal is processed to identify a reactive impedance of the available DMSD system reactive impedances required to damp power oscillations. Appropriate switches (32) are selected for supplying the required reactive impedance. A switching control signal is generated and output to each of the selected switches to synchronously open or close the switch at a predetermined instant.
