Patent CA-2442490-A1 (CA)
Title: Acidic-wastewater treating material and method of treating acidic wastewater
Inventor: OISHI TOHRU
IPC: C02F1/66
Filed: 2002-03-28
Abstract: A method of treating an acidic wastewater containing sulfate ions and iron ions, especially a wastewater from a pit; and a solid wastewater-treating material for use in the method. The wastewater-treating material is obtained by solidifying a mixture of rock wool with an inorganic binder comprising as major components one or more of the silicates, hydroxides, and oxides of alkaline earth metals and alkali metals and has a void content of 50 % or higher. When this wastewater-treating material is brought into contact with an acidic wastewater containing iron ions or sulfate ions, not only the wastewater can be neutralized but iron and harmful heavy metals such as arsenic can be removed therefrom. After use, the wastewater-treating material can be easily treated.
Patent CA-2448406-A1 (CA)
Inventor: GORDON NORMAN S
IPC: A61B17/58
Filed: 2002-06-04
Abstract: L'invention concerne un dispositif d'ancrage osseux, servant à fixer un tissu conjonctif à un os, qui comprend un disque conçu pour être inséré dans une partie d'un os auquel le tissu conjonctif doit être fixé. Le disque peut passer d'une position pliée dans laquelle il présente une section transversale réduite à une position déployée présentant une section transversale plus importante. La position pliée permet d'insérer le disque a travers un petit orifice dans une région d'os poreux située sous la couche corticale, puis le disque est actionné pour être placé dans sa position déployée de façon à être ancré en permanence dans l'os spongieux, étant donné qu'il est devenu trop large pour repasser en position proximale par ledit orifice et retourner ainsi dans la couche corticale. L'invention concerne deux modes de réalisation. Dans le premier mode de réalisation, le disque se présente initialement sous sa forme déployée, en acier à ressorts. Dans le deuxième mode de réalisation, le disque se présente initialement sous sa forme pliée, et l'acier à ressorts n'est pas requis.

Patent CA-2461913-A1 (CA)
Title: Ladle
Inventor: COLE JAMES BARRY
IPC: B22D41/02
Filed: 2004-03-25
Abstract: A liner for a ladle is formed of a body of refractory material defining a hollow interior which is bounded by a continuous sidewall. Within the interior is a barrier of refractory material which faces the interior surface of part of the sidewall and is spaced inwardly therefrom in the hollow interior of the body to define with said facing part of said sidewall a spout for discharging molten metal, in use, from the ladle. The barrier has two longitudinal edge surfaces received at two facing inner portions of the sidewall respectively which are extended inwardly. By providing these inward extensions the barrier can be positioned within the interior of the liner thereby obviating the need for an outward extension from the liner body to define a spout. This enables the liner to be used with ladle shells without the shell requiring modification to accommodate such an outward extension.

Patent CA-2468921-A1 (CA)
Title: Service access and conferencing system and method in a telecommunications network
Inventor: CHANEY ADAM
IPC: H04L29/06
Filed: 2002-12-06
Abstract: A system and method of providing a subscriber service to service users in a telecommunications network. In an Internet Protocol (IP) telecommunications network, a conference call may be established between a conference owner and a plurality of other conference participants. In networks utilizing Session Initiation Protocol (SIP) control signaling for call setup and control, the SIP REGISTER message is modified to indicate service capability information and optionally a traffic load indication for service providers. The REGISTER  message is sent to a modified Presence and Instant Messaging (PIM) server that stores presence information and the service capability information for registered service providers such as a conference server. The PIM server then notifies subscribing service users, such as conference participants, of the identity of the service provider that is registered on the network. The PIM  server may utilize the traffic load information to balance the traffic load between service providers by providing users with the identity of the service provider that is the most lightly loaded. For a conference call, after a conference owner identifies the conference participants and provides criteria for initiating the conference, the conference server identifies each participant's serving CSCF, and sends a request to each CSCF to notify the conference server when served participants are present and available. When the predefined number of participants are present and available, the conference server initiates the conference call.

Inventor: EROZ MUSTAFA
IPC: G08C25/00
Filed: 2004-09-03
Abstract: An approach is provided for generating Low Density Parity Check (LDPC) codes. An LDPC encoder generates a short LDPC code by shortening longer mother codes. The short LDPC code has an outer Bose Chaudhuri Hocquenghem (BCH) code. According to another aspect, for an LDPC code with code rate of 3/5 utilizing 8-PSK (Phase Shift Keying) modulation, an interleaver provides for interleaving bits of the output LDPC code by serially writing data associated with the LDPC code column-wise into a table and reading the data row-wise from right to left. The above approach has particular application in digital video broadcast services over satellite.

Title: Collision energy-absorbing device
Inventor: LONGO THOMAS W
IPC: B60R19/34
Filed: 2003-04-17
Abstract: A collision energy-absorbing device includes a body member connected between the frame assembly of a motor vehicle and a bumper beam. The body member collapses as the bumper beam and the frame assembly are moved relatively toward one another during a vehicle collision. The body member has a first telescoping portion and a second telescoping portion that are connected by a connecting portion. The telescoping portions have different cross-sectional dimensions to enable the telescoping portions to move one within the other into collapsing telescoping relation as the body member collapses with the connecting portion being deformed and received between the telescoping portions. One or more protrusions extending from one of the telescoping portions interfere with relative movement of the other of the telescoping portions to retard movement of the telescoping portions into telescoping relation.

Abstract: System and methods for data storage, retrieval, manipulation and display provide search engines and computer-based research tools for enabling multiple hierarchical points of view. Category definitions in the hierarchical data structures (105) can include lists of set members, like word arrays of set members (104), generative descriptions for determining set members (126), and fitness functions for determining fitness of a presented item for being a member of a set (328). Significance and interest values can be assigned to search categories to set threshold confidence levels for returning search results and for weighing the results, respectively. A user interface can present results in the form of browsing multiple hierarchical representations (163), wherein matching categories are differentiated from non-matching categories. Peer ratings can represent the ranking of search term results with relation to results using other search terms, providing an indication of the fitness of the search terms of returning satisfactory results.
