Title: Composite steel/concrete column
Inventor: VINCENT RICHARD
IPC: E04C3/34
Filed: 1998-05-14
Abstract: The composite steel/concrete column (2) comprises a longitudinally extending H-shaped steel assembly (4) having a pair parallel flange plates (6) and a web plate (8) interconnecting the flange plates and defining two opposite channel-shaped spaces (10). A plurality of spaced-apart transversal tie bars (12) are disposed along the steel assembly on each side of the web plate for interconnecting the flange plates.

Abstract: A method and a system for sharing bookmark information between a plurality of computer users, as well as for permitting a single computer user to retrieve the bookmark information from a plurality of computers. The bookmark information includes at least the URL of the Web page, but may optionally include other information as well, such as a brief description of the contents of the Web page, or of the area of interest according to which the Web page may be classified. The bookmark information may be selected, such that only a portion of the personal bookmark information of a computer user is shared. Furthermore, the other computer user or users with which the information is shared may be selected according to specific identification, according to which one or more individual users are identified as recipients, according to a category of such users, or a combination thereof. The category of users may be determined according to a shared area of interest, for example.   Preferably, such bookmark information is shared between users according to a "delta", such that only that information which has been altered since the last exchange of information is exchanged, in order to avoid multiple exchanges of entire bookmark information repositories between users. Also preferably, the bookmark information is exchanged between users who are subscribers to a system providing these services, such that for example advertisements may be sent to these subscribers. Furthermore, preferably statistics are kept with regard to the Web pages bookmarked by the users, for example in order to rate a Web page. As another option, such information may be used in order to provide a search engine with more details than simply keywords for searching for relevant Web pages according to a request of a user. For example, the search engine optionally determines the relevance of a particular Web page to a particular area of interest according to the number of users who have bookmarked that Web page. Thus, the system and method of the present invention are able to augment search engines as well as to enable sharing of bookmark information between two or more users.

Title: Method for measuring the availability of router-based connectionless networks
Inventor: D SOUZA KEVIN L
IPC: H04L12/26
Filed: 2000-02-28
Abstract: The availability of a connectionless network (10) is determined by first identifying all possible data destinations. Stated another way, all possible network endpoints are determined. Thereafter, the routing tables (36, 38 and 40) within the routers (12, 14, 16) of the network are examined to determine whether a route exists to each endpoint. The availability of the network is then established by comparing the available routes to endpoints to the number of endpoints. If a route exists to every endpoint, then the network 10 is fully available. The lack of a route to an endpoint diminishes network availability.

Title: Stud tensioning device for flange cover
Inventor: MALSBURY ALLEN S
IPC: B01J3/03
Filed: 1998-10-22
Abstract: A mechanism (1) for selectively securing a cover to a flange of a pressure vessel (15). The cover (14) and flange (12) each have openings that are aligned when the cover (14) is in position facing the flange (12). The mechanism (1) includes an anchor plate (18) having a hole therethrough. A piston (34) is slidable in a direction normal to the cover (14) in alignment with the opening therethrough. A stud (10) extends from to the piston (34) with a stud head (42) remote from the piston (34). The stud head (42) fits through the opening of the closer of the cover (14) and flange (12) and through a wider portion of the anchor plate (18) hole, and is positioned opposite the flange (12) and cover (14) from the piston (34) when the cover is positioned over the flange (12). The stud head (42) does not fit through a narrower portion of the anchor plate (18) hole. A resilient member (16) biases the piston (34) away from the cover (14). A selectively activated actuator overcomes the resilient member (16) and forces the stud head (42) away from the flange (12) and the anchor plate (18) moves between (i) a locking position, in which the narrower portion of the hole is aligned with the openings so that the resilient member (16) can bias the stud head (42) against the anchor plate (18), and (ii) an unlocked position, in which the wider portion of the hole is aligned with the openings so that the resilient member (16) can bias the stud head (42) into the enlarged portion of the anchor plate (18) hole.

Ce plastique est introduit sous forme de petites billes sélectionnées dans le groupe comprenant des billes de polyoléfine et polyphényloxyde qui ont été pré-expansées selon une réduction de densité de l'ordre de 75 %. La pression d'air est utilisée pour amener les billes dans la cavité (14) du moule, et la vapeur est injectée pour ramollir les billes et les lier de façon à former une masse intégrale. De plus, la couche extérieure de billes est liée à la feuille (18), une pièce d'un seul tenant étant retirée du moule. L'invention porte également sur l'ajout à la pièce finie, en un seul tenant, d'une structure cadre (30) de façon à faciliter sa fixation à une porte métallique ou autre support. Le cadre (30) peut être associé à des parties (10) du moule au moyen d'un certain type d'éléments de fixation. Le cadre (30) est ensuite intégré à la pièce en plastique au cours d'une étape de moulage, la pièce pouvant être ensuite fixée facilement à une porte métallique ou autre.
