Patent CA-2209715-A1 (CA)
Title: Systeme et procedes de radiocommunications par paquets, permettant d'acheminer de facon independante d'un protocole un paquet de donnees dans des reseaux de radiocommunications par paquets
Inventor: KARI HANNU
IPC: H04B7/26
Filed: 1996-01-08
Abstract: On décrit l'acheminement, indépendant d'un protocole, de paquets de données entre une station mobile de réseau de télécommunications par paquets et un intervenant (ordinateur central) connecté à un réseau extérieur. Un paquet de données d'un protocole étranger (IPX) est transféré par un réseau de radiocommunications par paquets à l'aide d'un deuxième protocole (X.25) en étant incorporé dans un paquet de données conforme à ce deuxième protocole. Le réseau de radiocommunications par paquets qui effectue ce transfert n'est donc pas tenu de comprendre le protocole du paquet de données étranger transféré ou d'interpréter la teneur de ce paquet de données. Un réseau de transmission de paquets de données est connecté à d'autres réseaux de radiocommunications par paquets, à des réseaux de données ou à un réseau de base reliant des réseaux de transmission de paquets de données par l'intermédiaire d'un node de porte (GPRS GSN) qui utilise le protocole interne au réseau (X.25), à destination du réseau spécialisé de transmission par paquets, et le protocole de chaque réseau à destination de ces autres réseaux. Quand un paquet de données est transféré par l'intermédiaire d'un node de porte d'un réseau à un autre, le paquet de données est incorporé dans un paquet conforme au protocole du nouveau réseau. Quand ce paquet de données, ainsi incorporé, arrive à un node qui accepte son protocole, il est dépouillé de ses éléments d'incorporation et acheminé en aval en fonction de son protocole.

Title: Image-recording element
Inventor: VISKI PETER
IPC: G03C8/40
Filed: 1997-01-31
Abstract: There are described heat-developable photosensitive image-recording elements which have an alkali-generating system incorporated therein. In the alkaligenerating system, a slightly water-soluble metal compound is reacted with a salt of 2-hydroxy-pyridine-N-oxide, or its derivatives, in the presence of a fluid such as water, to form an insoluble precipitate and the alkali required for silver image development during processing. The image-recording materials are useful as image-forming materials in thermographic and photothermographic processes.

Patent CA-2219285-A1 (CA)
Title: Transmission of text and data from crt
Inventor: BRZEZINSKI PHILIP S
IPC: G04G21/00
Filed: 1996-04-17
Abstract: A system and method is provided for remotely and optionally transmitting data to or programming a portable information device, such as a programmable watch (14), using a visual display device, such as a CRT monitor (16). The monitor displays a sequence of changing optical patterns ¢30(1) - 30(10)! used to optically transmit a serial stream of data. The optically programmable watch has an optical sensor (15) which detects the sequence of optical patterns to optically receive the data stream. The optical patterns transmit machinereadable serial data that can be detected by the optical sensor, but no meaningful information to a user. The visual display device therefore also displays a human-readable image in alphanumeric text that explains to a user the sequence of optical patterns being used to transmit the data stream. The human-readable image is displayed in a manner that renders it undetectable by the optical sensor of the programmable watch.

Title: High surface intermeshing profile reactor
Inventor: LOHE HANS
IPC: B01J19/18
Filed: 1998-01-14
Abstract: Disclosed is a polycondensation reactor for polyesters, polyamides or polyarylates in which a low I.V. material is introduced into the reactor and a relative high I.V. polymer exits the reactor. The reactor has at least two overlapping cyclindrical interior chambers, each with a rotating shaft through its length. Each shaft has a plurality of stirrers and spacers designed to wipe all interior surfaces of the reactor. The stirrers can be shaped as a cycloid or involute profile, for example. Generally the stirrers on each shaft are indexed from one another preferably by 90° and interdigitate with stirrers on the adjacent shaft.      Stirring the low I.V. material by rotating the stirrers (on the shafts) through the material spreads it into a plurality of thin films. At the temperature and vacuum conditions of the reactor, a volatile component is removed, thus causing the material to polymerize, by condensation, forming a relatively high I.V. polymer.

Patent CA-2237772-A1 (CA)
Inventor: YEUNG KWONG YU
IPC: E03D1/00
Filed: 1998-05-15
Abstract: Apparatus and a process is provided for restricting that portion of the flow of water which is directed through a tube to refill the bowl of a toilet after a flush. Typically, the bowl refills before the toilet tank fills so that some water overflows the bowl and is wasted down the sewer. Accordingly, a conduit is connected to the discharge of the bowl refill tube. The conduit has a tapered bore which diminishes continuously from its inlet to its outlet. The diameter of the bore at the conduit's outlet does not permit sufficient water to discharge and refill the bowl after a flush. The conduit is formed of material which is readily cut. An objective bowl water is established. In a process of progressively trimming back the outlet of the conduit, an ever larger and larger diameter bore is exposed, increasing the amount of water discharged. Eventually, enough of the conduit is trimmed so that the operating water level in the bowl is tailored to the toilet's unique characteristics, reaching the objective water level and avoiding waste.

Abstract: A coarse particle kaolin clay is provided having an average Stokes equivalent particle diameter of about 4.5 - 6.0 microns, a BET surface area of about 8 - 11 m2/g, and preferably having a median Malvern particle size of about 9.0- 10.5 microns as determined by laser light-scattering measurement and a high aspect ratio preferably of about 12-14 as determined by Sphericity Model calculations. The coarse particle kaolin clay provides low viscosity build, good reinforcement properties and excellent surface finish qualities as a filler in thermoset composite materials, such as polyester molding compounds, and also provides excellent pigmenting properties in paints and industrial coatings. Preparation of the coarse particle clay involves blunging and degritting a crude kaolin clay, conducting three separate centrifugation steps with the desired product stream being, in sequence, the coarse underflow clay from the primary centrifuge, the coarse underflow from the secondary centrifuge, and then the fine overflow from the tertiary centrifuge, followed by magnetic separation, screening, chemical leaching, drying and milling to produce a kaolin clay product having the above-described physical properties and performance characteristics.

Patent CA-2253950-A1 (CA)
Inventor: QUINN MARTIN S
IPC: H04L29/12
Filed: 1998-03-17
Abstract: A network system includes a hierarchical directory which includes a plurality of nodes in a tree structure. Each node contains a set of address mappings relating a first address to a second addres. An address resolution request attempts to resolve a first address to a target address in a node in which the first address is located. If the resolution of this first address cannot be accomplished in this first node, the process moves to a next higher node in the hierarchy and again attempts to resolve the request. The address mappings become less specific as the process moves up the hierarchy and, as a result, more general addresses will be used to resolve the first address to the target address.
