Title: An injection syringe
Inventor: HANSEN STEFFEN
IPC: A61M5/315
Filed: 1999-01-28
Abstract: In an injection syringe comprising a housing (1), a piston rod (6) with a not circular cross section and an outer thread (7), a piston rod drive comprising a piston rod guide (85) mating the cross section of the piston rod (6) and a nut (4) which is not axially displaceable and mates the thread (7) of the piston rod (6) to form a self locking thread connection, and a dose setting mechanism comprising a not self locking thread connection along which an injection button by rotation of a dose setting element (81) is screwed out to project from the housing (1) and which thread connection by axial returning of the injection button (88) transforms this axial movement into a rotation of one of the piston drive elements (85) relative to the other one (4). A unidirectional coupling between the nut member (4) and the piston rod guide (85) allows rotation in one direction by which the piston rod (6) is transported in a distal direction. The coupling has an initial reluctance to be overcome before rotation takes place said reluctance being large enough to resist torques exerted during the dose setting.

Title: Procede d'extraction de fluide d'eclosion produit par du saumon de l'atlantique et d'utilisation dudit fluide
Inventor: RONG CHUNJUN J
IPC: C12N9/64
Filed: 1998-12-11
Abstract: Procédé permettant d'obtenir des endoprotéases (ou zonases) ayant une valeur commerciale à partir d'oeufs de saumons de l'Atlantique produits dans des écloseries. L'éclosion synchronisée, par exemple par élévation de la température, est suivie par le filtrage à travers des toiles à fromage. Le filtrat (fluide d'éclosion) peut être stocké pendant des mois ou des années (selon les conditions) sans perte d'activité. Les matières étrangères sont éliminées par centrifugation (16.000g, 2 x 15 mn) après ajout d'urée (2 ou 4 M, ou plus). On obtient ainsi des zonases extrêmement pures par des procédures chromatographiques simples (filtration sur gel, chromatographie d'affinité, isoélectrofocalisation) qui permettent d'atteindre une pureté élevée une fois que ces trois phases ont été effectuées en séquence. Toutes les préparations de zonases de saumon possèdent des propriétés enzymatiques précieuses pour ce qui est de la protolyse, à la fois en termes de catalyse et de stabilité.

Patent CA-2332013-A1 (CA)
Title: Process for the production of ultrafine powders
Inventor: MCCORMICK PAUL GERARD
IPC: C01F17/235
Filed: 1999-05-17
Abstract: A process for the production of ultrafine powders consisting of individual particles with sizes in the range of 1 nm to 200 nm, which is based on the mechanical milling of two or more non-reacting powders. The process includes subjecting a suitable precursor metal compound and a non-reactant diluent phased to mechanical milling which through the process of mechanical activation reduces the microstructure of the mixture of the form of nano-sized grains of the metal compound uniformly dispersed in the diluent phase. Heat treating the milled powder converts the nano-sized grains of the precursor metal compound into a desired metal oxide phase. Alternatively, the precursor metal compound may itself be an oxide phase which has the requisite milling properties to form nanograins when milled with a diluent. An ultrafine powder is produced by removing the diluent phase such that nano-sized grains of the desired metal oxide phase are left behind. The process facilitates a significant degree of control over the particle size and size distribution of the particles in the ultrafine powder by controlling the parameters of mechanical activation and heat treatment.

Title: Apparatus for producing orthohydrogen and/or parahydrogen
Inventor: CHAMBERS STEPHEN BARRIE
IPC: C25B9/17
Filed: 1999-06-21
Abstract: An apparatus for producing orthohydrogen and/or parahydrogen. The apparatus includes a container holding water and at least one pair of closely-spaced electrodes arranged within the container and submerged in the water. A first  power supply provides a particular first pulsed signal to the electrodes. A coil may also be arranged within the container and submerged in the water if  the production of parahydrogen is also required. A second power supply provides a second pulsed signal to the coil through a switch to apply energy  to the water. When the second power supply is disconnected from the coil by the switch and only the electrodes receive a pulsed signal, then orthohydrog en can be produced. When the second power supply is connected to the coil and both the electrodes and coil receive pulsed signals, then the first and seco nd pulsed signals can be controlled to produce parahydrogen. The container is self-pressurized and the water within the container requires no chemical catalyst to efficiently produce the orthohydrogen and/or parahydrogen. Heat is not generated, and bubbles do not form on the electrodes.
