Patent CA-2344041-A1 (CA)
Title: Apparatus and steam injection method for making a consolidated cellulosic product
Inventor: DODD WILLIAM R
IPC: B27N3/08
Filed: 1999-08-04
Abstract: Disclosed herein is a cellulosic composite article and steam injection press methods of making the same by combining a resin binder with cellulosic material to form a mixture and, thereafter, forming a mat from the cellulosic material/resin binder mixture and consolidating the mat in a pressing apparatus under heat, steam, and pressure to form the consolidatted cellulosic product. A steam injection platen includes elongated openings for injection of steam to the mat through an adjacent steam distribution plate. The steam distribution plate includes slots in fluid communication with the steam injection platen openings and is disposed over the openings in the steam injection platen to achieve homogeneous and complete steam distribution throughout the mat during consolidation. The steam is injected and removed through the same steam injection platen so that an opposed press platen can be textured or deeply contured to provide a variety of embossed designs in a major surface of the consolidated cellulosic product.

Title: Hypodermic syringe with selectively retractable needle
Inventor: BUSH CHARLES L JR
IPC: A61M5/50
Filed: 2001-05-25
Abstract: A syringe has a retractable needle and a barrel having an open proximal end and an open distal end defining a receiver with an inward shoulder. The barrel has a hollow bore, an elongate plunger with a proximal end and a distal open end with a cavity therewithin. A stopper occludes the open end of the cavity. The syringe has an elongate hub with a proximal flange. The hub is within and sized for slidable movement within the receiver at the distal end of the barrel with the flange defining a distal end of a chamber. There is a sleeve sized to fit with a clearance about the hub disposed between the shoulder and the flange when the hub is in the receiver, the sleeve having a sharpened proximal end disposed against the flange. The needle has a pointed distal end and a proximal end connected to the passageway of the hub with the pointed end of the needle extending outwardly. There is a spring disposed about the hub compressed to provide a bias between the receiver and the flange so that when a force greater than required to expel fluid from the chamber is applied, the plunger causes the cutting surface to cut through the flange and stopper and expose the cavity to allow the spring to urge the hub into the cavity in the plunger and retract the needle to a position within the syringe.

Title: Intelligent cell recovery
Inventor: O'DONNELL OWEN
IPC: H04W24/04
Filed: 1999-11-02
Abstract: A technique for restoring operation to a plurality of cells within a wireless communication system includes the step of estimating the traffic within each cell to provide a plurality of traffic measurements. These traffic measurements are stored. In the event of a disruption in service provided by the communication system, the measurements are retrieved. The system then restores operation to cells within the wireless communication system in an order based on the retrieved traffic measurements, e.g., such that the cell which had the heaviest traffic at the time of system disturbance is restored before other cells. This maximizes the revenue produced by the system and minimizes customer dissatisfaction.

Title: Systeme d'amorcage pour charges propulsives, fonctionnant par induction
Inventor: KERN HEINZ
IPC: F42B5/08
Filed: 2000-01-15
Abstract: Des différences de pressions gazeuses indésirables peuvent, notamment sur la plage inférieure de températures, apparaître dans les systèmes d'amorçage pour charges propulsives. Elles peuvent entraîner des augmentations de pression incontrôlées et endommager voire détruire le système d'arme. Les tentatives pour empêcher ce phénomène par des réductions de la quantité de poudre ont cependant entraîné, sur l'ensemble de la plage de températures, des pertes de puissance perceptibles de la munition, en ce qui concerne la portée et la force de pénétration des projectiles. Pour résoudre ce problème, il est prévu, selon l'invention, des corps de charge propulsive (1) comportant une douille (2) dont la paroi (6) présente au moins une bobine primaire (7a, 7b, 7c).
