Title: Zirconium modified synthetic alkali metal silicate pigment and method of making
Inventor: FREEMAN GARY M
IPC: C09C1/28
Filed: 1998-07-09
Abstract: A synthetic alkali metal silicate pigment is modified with a source of a water soluble zirconium ion to form an oxy-hydroxy zirconium  species  precipitate  on  the  pigment  surface.    The surface modified pigment is made by slurrying the pigment and reacting it with the source of a water soluble zirconium ion.          The   surface  modified  pigment  provides   improvements   over conventional synthetic alkali metal silicate pigments in terms of optical  properties,  particularly  in  paper  applications,  and physical properties, particularly in rubber applications.   The surface  modified  pigment  is  also  useful  as  an  extender  or replacement  for  TiO2,  a  conventional  synthetic  alkali  metal silicate  such as a sodium-aluminosilicate pigment,  a clay,  a calcined clay or the like.

Title: Digital video recorder error recovery method
Inventor: WEHMEYER KEITH REYNOLDS
IPC: H04N5/44
Filed: 1997-01-31
Abstract: A method for operating a video recording apparatus in one of a digital recording mode and an analog recording mode. The method involves recording a digital video bit stream in the digital recording mode and switching to the analog recording mode for recording the corresponding analog video signal in response to a fault condition. For example, the fault conditions may occur in response to improper copyright information, an analog recording media being loaded into the video recording apparatus or the digital video bit stream being absent while the video recording apparatus operates in the digital recording mode. The fault condition may be indicated to a user and switching to a different mode, such as the analog recording mode, may occur in response to receiving a user initiated command responsive to the indicated fault condition.

Patent CA-2249462-A1 (CA)
Inventor: AUDEBERT YVES
IPC: G06F21/35
Filed: 1997-03-21
Abstract: Le système comprend une première unité (2) sous forme d'une carte destinée à coopérer avec une seconde unité (3) pouvant donner accès à la fonction (1) sous certaines conditions seulement. Les deux unités sont équipées pour exécuter des logiciels permettant d'engendrer des mots de passe par chiffrement de plusieurs variables dynamiques, telles que par exemple une variable fonction du temps et/ou une variable fonction du nombre de demandes d'authentification formulées. Le chiffrement se fait à l'aide d'une clé de chiffrement dynamique. Afin de synchroniser les valeurs des variables engendrées de concert mais indépendamment les unes des autres dans les deux unités, seulement quelques digits de poids le plus faible de chaque variable sont transférés de la première unité (2) à la seconde (3) en les ajoutant au mot de passe transféré. L'information de synchronisation est combinée avec des variables correspondantes dans la seconde unité afin d'y calculer une valeur conduisant normalement à une concordance entre les mots de passe calculés respectivement dans les deux unités. La concordance peut alors libérer l'accès à la fonction.

Abstract: A resaw includes a frame having at least one head. The head includes a horizontal mounting beam with four wheels operatively mounted to the mounting beam. The wheels comprise an inner pair of wheels and an outer pair of wheels. The centers of the inner wheels are vertically offset from the center of the outer wheels. A band blade is mounted about the four wheels to define a first blade portion and a second blade portion which are spaced from each other.  A single head can simultaneously make two slices in a cant to cut two or more boards from the cant. The inner and outer wheels can be moved as a unit relative to the path of travel of a cant and the inner wheels can be moved relative to the outer wheels to enable adjustment of the thickness of the boards cut from the cant. In variations, the resaw can have two heads, and each head can have one, two, or more band blades. With a two head resaw, four slices can simultaneously be made in the cant. Where each head of the two head resaw has two band blades, eight slices can simultaneously be cut in the cant.

Patent CA-2271194-A1 (CA)
Inventor: WRONSKI LESZEK DARIUSZ
IPC: H05K7/14
Filed: 1997-10-24
Abstract: A compact, high speed switch packaging arrangement or package provides reduced path lengths for electrical paths through the package. In particular, a printed circuit board switch backplane supports a switching subsystem and connects the switching subsystem to pairs of electrical connectors with the pairs of connectors being positioned on opposite edges of the same side of the backplane. A plurality of port boards for processing signals to be switched by the switching subsystem each include pairs of connectors which intermate with the pairs of connectors on the backplane. Port circuitry on the port boards is connected to the port board connectors to minimize trace lengths on the port boards by routing ports to the nearest one of the two connectors. The port boards are mounted to the backplane such that signals from the port boards are routed to the switching subsystem from two opposite sides of the switching subsystem. This routing results in a star or radiating pattern of trace paths on the backplane to reduce trace lengths. Further, since the connectors on the backplane are placed on opposite sides of the switching subsystem, the port boards coupled with the connectors can extend over and above that portion of the backplane which supports the switching subsystem thereby placing the connectors as close as possible to the switching subsystem and, in turn, further reducing trace lengths on the backplane.

Abstract: A vacuum apparatus for easily forming a vacuum in any bottle or the like vacuum containers and for providing a stable sealing. A lower cylindrical member together with a disc member forms a space portion in which a vacuum or an atmospheric pressure is applied, and the lower portion of an upper cylindrical member is inserted in the space portion and divides the space portion into upper and lower spaces. With a downward movement of the upper cylindrical member, the upper space expands and draws air inside of a bottle, and with an upward movement thereof, the air introduced into the upper space is vented outside. At this time, a check valve is selectively opened and closed and is operated by a pressure difference applied thereon. By repetitive reciprocating movement of the upper cylindrical member, a high vacuum is formed in the bottle and is sealed by the check valve. The apparatus is adaptable in a vacuum bottle, a medical suction instrument or the like.
