Patent CA-2377777-A1 (CA)
Inventor: MILLAR CAROLINE ELIZABETH
IPC: H02N2/00
Filed: 2000-06-22
Abstract: The invention relates to a piezo-electric transformer circuit (200) incorporating a piezo-electric transformer (10) comprising a multi-element primary region (12) and a single element secondary region (14) mutually join ed together. In operation, the circuit (200) applies a drive signal to the primary region (12) to excite the primary and secondary regions (12, 14) int o longitudinal resonance, thereby generating a high potential signal at the secondary region (14). The drive signal is derived from the signal at the secondary region (14) in a self oscillating feedback loop configuration. The  transformer (10) is fabricated from a hard piezo-electric ceramic material having a dielectric loss of substantially 0.005 or less at 1 kHz. Although such a hard ceramic does not provide as high a charge coefficient as softer piezo-electric ceramic materials, it is found that hard ceramics provide surprisingly improved energy conversion when used in piezo-electric transformer power supplies.

Abstract: In a biomass extraction circuit there is a need for an improved evaporator. An evaporator (12) includes an inlet for a liquid solvent/biomass mixture, the inlet including a spray nozzle (27). The evaporator (12) includes a heated vessel wall (20a, 20b). When the solvent/biomass mixture flows through the nozzle (27), the pressure drop vaporises some of the solvent. The heated walls (20a, 20b) vaporise the remainder of the solvent. The solvent vapour vents from the evaporator (12) for recycling. Liquid biomass extract collects in the base of the vessel for draining and subsequent use.
Patent CA-2384716-A1 (CA)
Title: Improved magnetic hook or clip
Inventor: ADAMS WILLIAM E
IPC: F16B45/00
Filed: 2002-05-03
Abstract: A magnetic hook, jaw-type clip or spring clip has a rectangular housing containing magnets. A conventional hook or clip is attached to the housing. A finger tab extends from one edge or wall of the housing. When a user desires to remove the magnetic hook from a mounting surface he or she places a finger tip on a curved portion of the finger tab causing the upper edge of the magnetic hook to move away from the mounting surface. This results in a pivoting action forcing the magnetic hook away from the mounting surface with little or no sliding. A flexible fin may be placed adjacent the magnets and extend slightly beyond the housing. When the magnet is placed against a metal surface the flexible fin will bend to a smaller height and bear against the metal surface thereby improving the load carrying capacity of the device.

Abstract: La présente invention concerne un procédé permettant d'éliminer un fragment d'ADN cible ayant une longueur de paires de bases prédéterminée, à partir d'un mélange de fragments d'ADN, ledit procédé comprenant les étapes suivantes: un mélange contenant des fragments d'ADN, qui peut contenir les fragments d'ADN cible, est appliqué à une colonne de séparation contenant un milieu ayant une surface non poreuse, non polaire, le mélange de fragments d'ADN se trouvant dans un premier mélange de solvants contenant un ion antagoniste et une concentration de liaison d'ADN d'un solvant d'entraînement dans un cosolvant; les fragments d'ADN cible sont séparés du milieu grâce à leur mise en contact avec une deuxième solution de solvants contenant un ion antagoniste et une concentration de solvant d'entraînement dans un cosolvant qui a été préparé pour permettre d'éliminer du milieu les fragments d'ADN ayant la longueur de paires de bases de fragments d'ADN cible. Les fragments d'ADN cible peuvent être recueillis et éventuellement amplifiés. Lorsque le procédé est appliqué pour recueillir un fragment putatif, si celui-ci est présent, aucun fragment d'ADN ayant la longueur de paires de bases de l'ADN cible ne peut être présent dans le mélange. De façon alternative, des fragments d'ADN ayant la longueur de paires de bases de l'ADN cible sont présents dans le mélange. Cette invention concerne également un dispositif à pression ambiante ou à basse pression, servant à séparer des fragments polynucléotidiques d'un mélange de fragments polynucléotidiques, ledit dispositif comprenant un tube présentant un compartiment supérieur d'entrée de solution, un compartiment inférieur de réception d'éluant, et une unité fixe du milieu de séparation qui s'y trouve. Le milieu de séparation présente des surfaces non polaires qui sont dépourvues de cations plurivalents qui réagiraient sinon avec l'ion antagoniste pour former une couche polaire insoluble à la surface du milieu de séparation.

Title: Injection unit for a plastic injection moulding machine
Inventor: DANTLGRABER JORG
IPC: B29C45/50
Filed: 2001-04-28
Abstract: An injection unit for a plastic injection molding machine having a screw, having a motion spindle as first drive element, via which the screw can be rotationally driven for the plasticization and is movable in the axial direction for the injection, having a spindle nut as second drive element, which is coupled to the motion spindle via a motion screw thread, having a large electric motor which is arranged so as to be fixed to the frame and by which, while one drive element is held against rotation, the other drive element can be rotationally driven for moving the screw during the injection, and having a device which is arranged so as to be fixed to the frame and by which a rotational speed of the one drive element can be preset during the plasticization, this rotational speed being different from the rotational speed at which the large electric motor simultaneously drives the other drive element. In a known injection unit of this type, two equally large electric motors, which can both apply a large torque, are used, by which such a counter-torque is exerted on the motion spindle during the injection operation that the motion spindle does not rotate. On the whole, the known injection unit is quite expensive on account of the two electric motors designed for a high torque. In order to provide a more cost-effective injection unit, the drive element held against rotation during the moving of the screw for the injection can be locked by a releasable mechanical brake.

Abstract: A method of allocating data transmission resources in a packet-switched telecommunications system which comprises a terminal and a fixed network to which an operational entity is defined for defining resources for a radio bearer. Radio bearer resources are defined for the terminal on the basis of an application used on the radio bearer, and the used compression method of header fields in data packets is selected before the radio bearer resources are defined, the resources being defined in such a manner that they also comprise the capacity required by the selected compression method of header fields in data packets. The compression methods of header fields in data packets, which are supported by the terminal, are transmitted to the operational entity in the fixed network for defining the compression method to be used. Capacity is defined for the radio bearer in two directions, if the selected compression method of header fields in data packets requires a bi-directional connection.
