Title: Catalyst deterioration-determining device of an internal combustion engine
Inventor: TOYODA KATSUHIKO
IPC: F01N3/20
Filed: 1994-12-20
Granted: 1997-09-23
Abstract: A catalyst deterioration-determining device for an internal combustion engine, in which a temperature sensor for detecting the temperature of a catalyst body is eliminated, but high-precision determination can be made to the deterioration of the catalyst body.  To this end, a control unit determines, on the basis of a warm-up counter used for a catalyst body, whether or not the catalyst body is in a predetermined warm-up state.  The warm-up counter reckons in relation to any engine load of an internal combustion engine.  If the catalyst body is found to be in the predetermined warm-up state according to the above determination, the control unit determines whether or not deterioration-determining conditions for the catalyst body have been fulfilled.

Patent CA-2150063-C (CA)
Title: Completion of intelligent network telephone calls
Inventor: CARLSEN RALPH
IPC: H04W4/16
Filed: 1995-05-24
Granted: 1998-12-29
Abstract: Intelligent network telephone calls are processed by an intelligent terminal which cooperates with network elements such as the database that contains information with respect to such calls. When a call requiring intelligent network treatment is first made from an intelligent terminal, the terminal does not have the requisite information to complete the call; the call is thus processed by network elements such as the originating switch and the network database which attempt to find routing information for the call. However, if the call contains an indication that (a) the calling party requests a down load, and the database record associated with the dialed number indicates that routing information stored in the database is marked for down loading, then the routing information is down loaded and stored in the intelligent terminal. When a subsequent call to the same number and therefore requiring the same treatment is again made, the intelligent terminal now contains the requisite routing information needed to complete the call. In this circumstance, the call does not have to be processed by intelligent network elements such as the network database. The routing information can be a destination number, or an indication of the particular network (e.g. wireline, cellular or CATV) that will carry the call, or other similar information.

Abstract: This invention relates to improvements in meat treatment and more particularly to improvements in methods and apparatus for treatment of meat in handling, storage, transportation and at sale.      The invention comprises primarily the method of treatment of meat by exposing said meat to a controlled gas environment including oxygen under pressure in excess of atmospheric for a predetermined period of time. The method may also include the step of pre-treating the meat in a substantially anaerobic environment for a sufficient time to achieve a predetermined close down of aerobic bacteria on the meat, and suspension of most biochemic effects of oxygen on the meat. Subsequently, the method includes the treating said meat in the aerobic conditions including oxygen under pressure. The method also includes the prepackaging of meat in at least partially gas permeable packaging suitable for use in a retail safe environment, prior to aerobic gas pressure under treatment.     When treated according to the invention, the applicant's have found improved shelf life and appearance of meat over traditionally handled product.

Title: Technique for obtaining and exchanging information on world wide web
Inventor: ANUPAM VINOD
IPC: G06Q10/10
Filed: 1997-05-26
Granted: 2000-04-11
Abstract: Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. The users or collaborators in a session are connected by one or more controllers in the server system.  When a collaborator creates or joins a session, mobile code is transmitted from the system to the collaborator's computer to create a surrogate thereon, which monitors the collaborator's interaction with a web browser on the computer.  The controllers communicate with all the surrogates of the collaborators to coordinate the collaborative browsing effort.  When one of the surrogates detects a change by a collaborator of a uniform resource locator (URL), the new URL is communicated through the controllers to the surrogates of all other collaborators in the session.  As such, the collaborators are able to move from one URL to another to browse information in a synchronous manner.  In addition, the collaborators can interactively communicate with one another in real time through the respective surrogates during the session.

Granted: 2007-01-09
Abstract: Un maillon (1) de raccordement de chaîne comprend un assemblage de pièces que l'on peut désassembler, qui permet audit maillon (1) d'être ajusté sur deux sections adjacentes de chaîne et est composé d'éléments (2) d'extrémité en forme de U, lesquels sont destinés à retenir lesdites sections de chaîne, présentent des parties femelles (7) servant à loger des parties mâles (4), et permettent ainsi de joindre les éléments (2) afin d'assembler le maillon. Chaque partie femelle (7) présente une largeur supérieure à celle de la partie mâle (4) correspondante, et la différence de largeur (espace) est occupée par une clavette (8), que l'on ajuste dans cet espace de manière à ce que s'exerce sur le maillon une précharge déterminée; à cette fin, on place d'abord la clavette (8) dans l'espace, dans une première position ne requérant pas d'ajustage en force, puis on l'entre en force sur une distance déterminée afin de la déplacer de cette première position vers une seconde position, provoquant ainsi une précharge de compression sur la partie mâle (4) ainsi qu'une précharge de tension sur le matériau entourant la partie femelle (7). On termine l'assemblage du maillon par une colonnette (15). On a prévu un outil spécial pour déplacer la clavette (8) et mettre celle-ci dans la seconde position. On a également prévu des moyens (13) pour faciliter la libération de la clavette (8) afin de la remettre dans sa première position pour désassembler le maillon. Cette configuration permet d'obtenir la précharge voulue sans qu'il soit nécessaire d'usiner avec une précision coûteuse la partie mâle et la partie femelle.

Abstract: A blanket passes over a concave shoe which is urged against a backing roll to form a press nip. The ends of the blanket are attached to circular heads. The transition from the nip-imposed cardioid shaped to the circular shape maintained by the heads results in a region of the blanket subject to fatigue. The heads are mounted on journals for motion between inboard stops and outboard stops which are spaced apart approximately 4 inches in the cross machine direction. Positioning of the heads on the journals is controlled by four hydraulic pistons mounted between the support beam and each head. Multiple hydraulic systems are controlled to extend the life of the blanket by alternating between holding the back head fixed and letting the front head float and fixing the front head and letting the back head float.
