Patent CA-2348787-C (CA)
Inventor: RICHTER GEORGE NEAL
IPC: C02F11/12
Filed: 1999-12-03
Granted: 2004-11-30
Abstract: The high intracellular water content contained within the cell walls of the bacterial cells of a dewatered biosludge is reduced by removing the intracellular water in a denaturing operation. This operation comprises heating the biosludge (2) at a temperature (4) sufficient to weaken the bacterial cell walls. The weakened cell walls are then exposed to a reduced pressure (g) sufficient to form vapor within the cell and to thus rupture the weakened cell walls and thereby release the intracellular water. The water-reduced concentrated biosludge (24) can then serve as a fuel source in a partial oxidation reaction for the production of synthesis gas.
Patent CA-2357340-C (CA)

Abstract: La présente invention consiste en un système de résistivité à la propagation qui fait appel à une ou plusieurs antennes à cadre de transmission, ou « transmetteurs », et au moins deux antennes à cadre de réception, ou « récepteurs ». Le système fait appel à un outil de résistivité de puits de forage qui peut prendre la forme d'un outil de mesure de fond pendant le forage (MWD), ou d'un outil de réseau filaire. Deux transmetteurs ou plus peuvent être espacés également de chaque côté de deux ou de plusieurs récepteurs. Deux ou plusieurs fréquences sont transmises et reçues simultanément. Des fréquences multiples peuvent être transmises de chaque transmetteur ou de transmetteurs séparés au même moment. Des fréquences multiples sont reçues et analysées simultanément par les récepteurs électroniques, réduisant de la sorte le temps de mesure pour des mesures de fréquences multiples. Dans une réalisation de l'invention, les deux transmetteurs émettent simultanément. Un transmetteur fonctionne à haute fréquence, et le second transmetteur, à une fréquence plus basse. Le signal à haute fréquence pénètre une distance radiale relativement peu profonde dans la formation, et la fréquence plus basse, une profondeur radiale que dépasse celle de la haute fréquence. Des mesures composées prises aux deux profondeurs radiales servent à compenser des facteurs qui ont des effets négatifs sur les mesures de résistivité dans la région immédiate du trou de puits, par exemple l'invasion, les variations des dimensions du trou, le fluide du puits, et ainsi de suite.

Title: System and method for electronically exchanging value among distributed users
Inventor: LEVCHIN MAX
IPC: G06Q40/00
Filed: 2000-04-28
Granted: 2012-02-07
Abstract: A system and method are provided for facilitating a value exchange transaction involving multiple parties. The system may comprise a synchronization server for exchanging transaction details with client devices, a communication server for registering new users, a financial server for interacting with external financial institutions, and a security server for ensuring the security of value exchange transactions. In one method, a first party initiates a transaction on a client (e.g., a mobile computing device) by selecting or inputting an identifier (which may be pre-existing, such as a telephone number) of another party and a value to be exchanged. The transaction may be conducted while the parties' client devices are electronically connected or may be conducted by one user on one device. Transactions are communicated to a system server during a synchronization between a party's client device and a system server. When the transaction is submitted to the system, if the second party is not a registered user of the system he or she is invited to register and complete the transaction.

Title: Dual ended hair remover
Inventor: PORAN YEHUDA
IPC: B26B19/26
Filed: 2001-06-14
Granted: 2009-02-03
Abstract: A dual ended hair remover which includes a casing having a motor, an epilating head for plucking hairs from the skin of a user attached to one end of the casing, a depilating head for cutting the hairs from the skin of the user attached to the other end of the casing, and a handle which covers on of the epilating and depilating heads while providing power to the other one of the epilating and depilating heads. The handle fits over one or the other end of the casing and provides power to the head which is not covered. The handle may also simultaneously provide power to the head which is covered. The handle protects the user and the unused head by covering the unused head and provides power to at least the head which is in use. Further, by incorporating the epilating and depilating heads on the casing at the same time and at opposite ends, ease of use is obtained. Still further, in the instances that only the head which is in use is being driven, power conservation is achieved.
