Patent CA-2359573-A1 (CA)
Inventor: BABICH JOHN W
IPC: A61K47/48
Filed: 2000-01-19
Abstract: The present invention provides novel agents for specifically targeting and detecting or treating focal sites of infection or inflammation in a subject.  The diagnostic agents of the invention rapidly localize at sites of infectio n or inflammation. In addition, the agents exhibit a relatively high target-to - background ratio and rapid clearance from the background and the target particular when administered as a bolus intravenously. Further, clinical pharmakonetic studies indicate that administration of colony stimulating factors in an amount effective for targeting would be relatively safe. The invention is based, at least in part, on the surprising finding that radiolabeled G-CSF effectively localizes to sites of infection. This empiric al result is surprising, since the expression level of CSF receptors on cells h as been found to be relatively low, compared to the expression level of other growth factor receptors on hematopoietic cells (Park et al., "Hemapoietic Growth-Factor Receptors" p. 39-75 in). Based on the cross-reactivity between  CSFs and CSF receptors (Walker, F., and A.W. Burgess (1987) J. Cell. Physiol . 130:255-261), it is expected that other CSFs will also bind to sites of infection.

Abstract: The "Buoyant Gravity Engine" (hereafter referred to as BGE) is a mechanical device used to create electrical energy. The BGE has two main parts: The engine housing, a reinforced concrete boxlike structure which is firmly anchored to the earth or the sea floor, and the float chamber, a reinforced concrete box which floats within the engine housing. The float chamber is air filled and contains the generating system.  Continuous cables are suspended vertically from the center ceiling of the engine housing into the center of the float chamber around a spool and back down to the center of the engine housing floor. These cables provide tension to turn the spool and the generators as water enters and leaves the area. surrounding the float chamber. In an ocean version, the tide will provide lift and fall. In the land version, any low volume water source suffices.

IPC: G06Q10/00
Filed: 2002-02-01
Abstract: A method and system for computing the price for shipping goods. The method includes causing a computer to deliver first information to a user prompting the user to enter at the computer information about a rail transportation service for shipment of goods by one or more railcars. Information about a basic pool of railcars is received and filtered based on one or more filtering criteria to produce a filtered pool of railcars. The computer is then caused to deliver second information to the user prompting the user to select at the computer one or more railcars among the filtered pool of railcars for the shipment of goods. A price for the shipment of the goods is then computed at least in part on the basis of the rail transportation service and the one or more characteristics of the railcars in the filtered pool of railcars selected by the user.

IPC: B42C11/00
Filed: 2000-06-23
Abstract: A system for automating the creation of a printing master and a cover templa te for a document so that the cover would perfectly wrap around the document to  form a book. The system prepares the document for binding by setting up page - by-page printing instructions, scaling the document if required, and setting  up a template for a cover. The system sets up printing instructions for the document by collecting instructions for each page "range" in the book. The operator of the application may specify the type of paper to be used for eac h of the page ranges and the printing format. Once the page range printing instructions have been specified, the system next determines the size requirements for the cover based on the size of the original file and the thickness of the document, which is based on the type of paper used and the number of pages involved for each type of paper. The application optimizes ("scales") the text and page size to fit within the cover. Finally, the syst em next creates three output files: (1) the formatted document, (2) a template for the cover, and (3) a job summary file.

Title: Press and delivery system for a press
Inventor: WHITE JOHN
IPC: B23P19/06
Filed: 2000-12-15
Abstract: A press has a bush (56) set in a cylinder (54) which may then be rotated to position a stud (14) over a sheet of metal into which it is to be inserted. The cylinder is then lowered to insert and fix the stud in place. In a stud delivery system, studs (14) are fed through a delivery tube (12) shank first into a breech (20) in which a pair of pivoted members (24, 26) form a half barrel.  The pivoted members (24, 26) are biased towards each other and their ends remote from the delivery tube (12) are shaped to form a conical aperture (34). A thrust member (38) can push a stud (14) along the breech (20) so that the stud tip passes into the tapered aperture (34), the stud shaft then being horizontal. As the stud is pushed further along the breech, passage of the stud head (18) through the tapered aperture (34) forces the pivoted members (24, 26) apart.  After passage of the head (18), the pivot members (24, 26) return to their former position.

Inventor: BERTENYI BALAZS
IPC: H04L12/28
Filed: 2001-04-10
Abstract: In a technique for setting up calls in IP mobile networks, when an application level in a mobile station sends a setup message to set up a multimedia call, before sending such a message over the radio interface, the mobile station performs the appropriate procedures to setup the appropriate bearers over the radio interface and in the network to satisfy the call requirements specified by the application level in the setup message. The technique applies to both mobile originated calls and mobile terminated calls, the mobile station performing the transport level procedures after having received a setup message and before sending a confirmation/call acceptance message back to the calling party. Furthermore, the allocation of radio resources for PDP contexts that will be used to carry the media of a multimedia IP call is delayed so that no radio resources are allocated to the PDP contexts activated before the call control signaling is exchanged. The radio resources are allocated only when the call signaling has been completed and the called party has accepted the call and indicated the call characteristics that it can support. An indication is forwarded from the SGSN to the GGSN advising that no packets are to be sent on the PDP context because there are no radio resources for the PDP context. Quality of service negotiations for RAB are effected with an additional parameter that contains either a list of alternative values or the lowest acceptable value.

Abstract: La présente invention permet de palier les inconvénients des systèmes de commande de moteur de centrifugeuse de l'état de la technique, un système de commande (144) de moteur de centrifugeuse comprenant un module de commande logique (146), une ou plusieurs cellules d'énergie (148), et un ou plusieurs contacteurs (150). Le module de contact logique est capable de servir d'interface avec le système de commande de centrifugeuse principal et sert à commander les cellules d'énergie et les contacteurs pour fournir une montée en tension permettant d'accélérer le panier de centrifugeuse. En tant que tel, le module de commande logique permet d'éviter les problèmes de courant de fuite liés au démarrage direct du moteur de centrifugeuse. Les cellules d'énergie reçoivent une tension de l'alimentation électrique principale (152), et fournissent aux contacteurs une puissance variable servant à commander la vitesse du moteur de centrifugeuse. De plus, la configuration des contacteurs multiples permettant d'inverser la puissance alimentant les enroulements du moteur de centrifugeuse, peut permettre de supprimer la nécessité d'utiliser un second moteur à direction inverse.

Title: Isolator bar for acoustic instruments used in downhole formations
Inventor: BRADLEY RICHARD W
IPC: G01V1/52
Filed: 2003-03-11
Abstract: An isolator bar of acoustic instruments used in downhole applications is made of a substantially cylindrical tube of metal of the type from which downhole instrument housing is usually made. A plurality of slots are placed in the tube at angles which are between 10 to 80 ° angle relative to the longitudinal axis of the tube. The isolator bar is equipped with traditional mechanical means with which it is incorporated in the acoustic instrument, placed between an acoustic transducer and an acoustic sensor or sensors utilized in the instrument. The angled slots cause sound waves traveling through the isolator bar to travel through multiple and extended path to the acoustic sensor, without significantly weakening the structural strength of the isolator bar.
