Title: Liquid flow rate control device
Inventor: DARLING PHILLIP H JR
IPC: A61M5/40
Filed: 1996-09-24
Abstract: A fluid flow rate control device comprises a first vented fluid chamber (60) having an upper fluid inlet end with a hollow spike (46). A free floating float valve (70) in the first chamber blocks the flow of fluid into the first chamber from a fluid container (12) providing a constant pressure head. A  lower end of the chamber is connected, through a flow regulator (66), to an upper inlet end of a second, vented, drip chamber (62), the lower end of which is adapted for connection to a discharge tube. A second, free floating float valve (140) in the second chamber blocks the flow of fluid from the second chamber into the discharge tube when the fluid level in the second chamber is at or below a preestablished minimum level and blocks flow of fluid into the second chamber when the level in the second chamber reaches a preestablished level.

Patent CA-2256934-A1 (CA)
Title: System for electronic repository of data enforcing access control on data retrieval
Inventor: MIRLAS LEV
IPC: H04L9/00
Filed: 1998-12-23
Abstract: When an electronic document is made available for review by other entities, it is often convenient to store the document in a repository or database managed by a third party. A system is provided in which the originator of the document is able to ensure the integrity and security of its document filed with a third party repository without having to trust the administrator of the repository. Both the document originator and the repository administrator have vault environments which are secure extensions of their respective work spaces. The vault of the document originator encrypts a document that it receives from the originator, prior to forwarding it on to the vault of the repository. On receipt of the encrypted document, the repository's vault signs the encrypted document itself before storing the document in the electronic repository and returns to the originator's vault proof of deposit of the encrypted document in the form of a copy of the signed encrypted document. An access control list identifying access ownership privileges for the document are also stored in the repository. Updates to the access control list are under the control of document originator, or another computer designated by the document originator. When a request is made to view the document, it is made from the vault of the requesting party (a secure extension of the requesting party's work space) to the repository's vault. The repository's vault retrieves a copy of the encrypted document which it forwards, along with the requestor's identity to the originator's vault. The originator's vault verifies that the access control is valid, then verifies that the requestor is authorized to view the document from the access control list, then decrypts the document and forwards the decrypted document directly to the requestor's vault. The requestor provides proof of receipt of the decrypted document.

Abstract: Le procédé de notre invention est un anti-bactéricide et anti-viral; le plus proche du plasma sanguin. Donc, le plus compatible des anti-viraux existants pour l'être humain. De ce procédé, tant de sous produits peuvent être utiles à l'Homme. D'une part, ce procédé peut être développé dans les milieux tels que: médical et médicinal, médecines vétérinaire, dentisterie, dermatologie et, d'autre part, agricole, sanitaire, etc. Par nos expériences, il est démontré que l'eau de mer possède les mêmes compositions chimiques que le sang humain. Quant à l'utilisation d'un antibiotique biologique pour l'être humain, nous pouvons donc conclure qu'il est acceptable sous tourtes ses formes. Selon les recherches élablies sur l'eau de mer, notre invention a pour but de commercialiser un ou plusieurs produit(s) efficace(s) à l'être humain sous différentes formes, tels que: nébuliseur nasal propulsé par le protoxyde d'azote et un buccal propulsé par le monoxyde d'azote, rince-bouche, produits nu dérivés sanguins injectables ou transfusables ainsi que des produits pour la culture biologique. Il est nécessaire de préciser qu'il n'y a aucun effets secondaires ni de contre-indications pour l'être humain et, par conséquent, aucun inconvénient n'est à signaler quant à la fabrication ou à l'utilisation de quelconque produit issu de ce procédé. Il s'avère donc sans danger pour quiconque puisque l'eau de mer et le sang sanguin sont de même composition chimique.

Inventor: HASAN RIAZ
IPC: B25B21/00
Filed: 1999-04-12
Abstract: In a roofing washer-dispensing and fastener-driving machine, which has a fastener-feeding tube, a fastener-engaging pawl is mounted operatively to the tube, near its upper end. The pawl is pivotable between a normal position wherein the pawl is arranged to engage a fastener dropped into the tube so as to prevent the fastener from dropping through the tube and a pivoted position wherein the pawl is arranged to disengage from the fastener. An elongate rod is arranged to pivot the pawl from the normal position into the pivoted position when the machine is operated. In the same machine, a magazine adapted to hold a stack of such washers is improved so as to have a bridge mounted pivotably to one of two side walls of the magazine and a cover is mounted adjustably to the bridge, so that the cover in an upwardly adjusted position is inserted into the magazine, above a stack of such washers in the magazine, when the bridge spans the side walls and so that the cover is removed from the magazine when the bridge is pivoted to a position wherein the bridge does not span the side walls. The cover is mounted to the bridge via a rod, along which the cover is movable. In the same machine, a shuttle adapted to be reciprocatingly driven is improved so as to have a transverse groove, in which an elongate brace having a pivot pin at each end is fixed by fasteners so as to bear against the leading and trailing edges of the groove, and a transverse rib adapted to engage the lowermost washer in a stack in the magazine is defined by a removable element.

IPC: G02B6/36
Filed: 1997-10-29
Abstract: La présente invention concerne un arrangement à centrage automatique de corps microstructurés, en particulier de composants microoptiques sur l'un des substrats servant de support. C'est un procédé bien connu de doter les composants microoptiques de pièces ajoutées qui s'intègrent dans les cavités prévues à cet effet. La présente invention vise à améliorer l'orientation des composants (K1, K2) les uns par rapport aux autres de telle manière que, lorsque l'on introduit les pièces ajoutables (Z1, Z2) dans lesdites cavités (A), il en résulte une déformation. Cette déformation peut concerner les pièces ajoutées ou les cavités directement ou un matériau façonné situé entre les pièces ajoutées et les cavités. Cette déformation entraîne une amélioration des caractéristiques d'autocentrage. En outre, les tolérances de fabrication sont plus faciles à compenser. Lorsque le corps ne peut être pourvu d'une pièce ajoutable appropriée, on utilise un support intermédiaire, à savoir un corps plastique fabriqué par exemple selon la technique LIGA.
