Title: Electronic mail system with advertising
Inventor: SHAW DAVID E
IPC: G06Q30/02
Filed: 1997-04-11
Abstract: A system (100) for providing scheduled messages to a remote user (101) in a batch oriented system. In a preferred embodiment of the present invention, a user (101) creates and/or reads electronic mail locally. While the user (101) creates the electronic mail, a message is displayed to the user (101) on a portion of the local monitor, the message preferably changing in accordance with a local display schedule and stored on a local storage device. The message is preferably targeted to the particular user (101). When the user (101) is ready to transmit the e-mail created and/or receive e-mail addressed to him, the user's local client establishes a connection via a modem (102) with a remote e-mail server system (104). The remote e-mail server system (104) not only receives the e-mail transmitted by the user (101) and/or transmits e-mail addressed to the user (101), but also, updates the user's local messages in accordance with a distribution schedule. After, the e-mail and message updates are transmitted, the user's local client computer is disconnected from the remote e-mail server system (104).

Title: Process for returning finely dispersed solids discharged with a carrier gas from a reactor vessel
Inventor: SCHENK JOHANNES
IPC: C21B13/00
Filed: 1997-10-24
Abstract: In a process for returning finely dispersed solids discharged from a reactor vessel (1) with a carrier gas through a discharge point (2) of the reactor vessel (1) to a return point (15) of the reactor vessel (1), the solids are separated in a solid separator (4), in particular a cyclone separator, then returned with a carrier gas to the reactor vessel (1) while a differential pressure is maintained between the solid separator (4) and the return point (15). When the solids enter the reactor vessel (1), they are at least partially gasified and/or burned with oxygen supplied for that purpose. To enable the solids to be returned without moving parts which would be exposed to abrasion, in a continuous and controlled manner, the separated solids are directly and continuously aspirated by the solid separator (4) by means of a propellant gas and by an injector effect, accelerated and supplied to the reactor vessel (1).

Title: An improved method for the production and purification of adenoviral vectors
Inventor: CHO TOOHYON
IPC: A61K35/761
Filed: 1997-11-20
Abstract: The present invention addresses the need to improve the yields of viral vectors when grown in cell culture systems. In particular, it has been demonstrated that for adenovirus, the use of low-medium perfusion rates in an attached cell culture system provides for improved yields. In other embodiments, the inventors have shown that there is improved Ad-p53 production with cells grown in serum-free conditions, and in particular in serum-free suspension culture. Also important to the increase of yields is the use of detergent lysis. Combination of these aspects of the invention permits purification of virus by a single chromatography step that results in purified virus of the same quality as preparations from double CsC1 banding using an ultracentrifuge.

Patent CA-2275218-A1 (CA)
Title: Positive flow valve
Inventor: BUI DENNIS M
IPC: A61M5/00
Filed: 1997-12-15
Abstract: A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip. The fluid space within the valve automatically and reversibly increases upon insertion of the medical implement into the cavity and decreases upon withdrawal of the medical implement, such that a positive flow from the valve toward the catheter tip is effected upon withdrawal of the medical implement, thereby preventing a flow of blood from a patient into the catheter when the medical implement is removed from the valve.

Patent CA-2277438-A1 (CA)
Inventor: FRIED TOMAS
IPC: H04W72/08
Filed: 1998-01-09
Abstract: A method and apparatus are provided for assigning radio network control in a mobile communications system (10) that offers two or more types of bearer services (14, 16). The mobile network (12) broadcasts an initial control message that orders certain mobile terminals (20) to suspend use of their normal terminal-based radio network control decisions and to accept radio network control orders from the land mobile network (12). A subsequent control message can order the resumed use of normal terminal-based radio network control decisions. Consequently, the mobile network (12) can use virtually the same control logic for all of the mobile terminals (18, 20) that it serves, regardless of the type bearer service (14, 16) being carried. As a result, radio signal interference between mobile terminals (18, 20) carrying the different bearer services (14, 16) can be minimized.

Patent CA-2280549-A1 (CA)
Inventor: BYRD ROBERT K
IPC: A01D34/73
Filed: 1999-08-20
Abstract: A cutter blade is pivotally attached to a blade carrier so that it may operate as a flail. The blade carrier itself rotates about a drive shaft spaced from the pivot axis. A pivot pin is received in respective bores of the cutter blade and the blade carrier; a distal, protruding portion of the pivot pin is threaded. A pair of clamping collar halves each have a threaded surface which threadedly engage the threaded portion of the pivot pin shaft. After the correct amount of axial play between the cutter blade and the carrier is adjusted by rotating the collar halves on the shaft threads, the collar halves are clamped together on the pivot shaft using fasteners so as to affix the clamping collar halves to the shaft.

Abstract: On améliore la conservation de la membrane cellulaire des globules rouges et des concentrés de plaquettes en ajoutant entre 1 mM et 10 mM de L-carnitine et de dérivés de celle-ci. Cette amélioration permet d'étendre la période de viabilité de globules rouges et de concentrations de plaquettes conditionnés au-delà des périodes admises jusqu'à présent. En outre, les matières traitées de la sorte présentent une demi-vie de circulation étendue lorsqu'elles sont transfusées à un patient. L'amélioration de la conservation de la membrane résultant de ce procédé permet d'irradier des récipients hermétiquement fermés de produits sanguins et de rendre sensiblement stériles ces derniers tout en détruisant les leucocytes qu'ils contiennent.

Patent CA-2291927-A1 (CA)
Inventor: RUSSELL PAULINE H
IPC: B65G57/24
Filed: 1999-12-07
Abstract: An end effector designed to be used with a computer- or processor-controlled industrial robot and to grasp layers of containers wrapped in packaging material. The end effector has a main body and two hands mounted on the main body, opposite one another. Each hand is powered by an actuator and operable to move between a first retracted, position and a second, extended position. Each hand has a plurality of fingers. In one embodiment each hand has numerous, relatively thin fingers that are designed to flex slightly when gripping a load. In another embodiment of the invention each hand has relatively few fingers and each finger is relatively rigid. Regardless of the type of fingers used, to pick up a load the end effector is moved into position by the robot over a layer of boxes and the hands are closed around it. A synchronization mechanism coupled to the first and second hands helps ensure that the hands open and close at a uniform rate. A vacuum assist system is then engaged to help maintain the grip on the layer of boxes. The vacuum assist system includes two vacuum plates coupled to the main body by an actuator and a row of vacuum devices coupled to the plates.  The row of vacuum devices is movable by means of the two actuators between a first, upper position and a second, lower position. Once the hands have grasped a layer of boxes, the vacuum devices are lowered to engage the seam between adjacent boxes and provide additional gripping, i.e., a "vacuum assist."
