Title: Method and associated device for removing material from body
Inventor: GELBFISH GARY A
IPC: A61B10/00
Filed: 1995-12-15
Granted: 2007-06-26
Abstract: A pull push device for removing a clot. The device includes an elongate tubular member having a suction port and an irrigation or fluid pressurization port respectively con-nectable to a vacuum source and a pressurizable fluid reser-voir. The tubular member also has a clot intake port positionable through a patient's skin inside a clogged vas-cular vessel. The vacuum source enables clot suction into the clot intake port for severing while liquid pressure supplies fluid for clot ejection and device clearance. A single piece rotating or reciprocating cutter and intake closure component is mounted inside the tubular member for closing the clot intake port upon each small vacuum assisted severing of clot mass by the cutting element. By simultaneously severing the clot and closing the intake port by the closure component, the device automatically converts from a suction to a pressure mode, thus ejecting any clot through the suction port. The ordered and continual suck, cut, push, pull tandem ejection system is aided by an automatic anticlogging mechanism which is operative when a sucked clot obstructs suction through the tubular member. This self-limiting feature closes off further suction and ends the process of clot intake. Only after window closure and clot ejection has occurred is vacuum restored to the intake port so that more clot may be sucked into the device for processing.

Title: An inverted e-shaped antenna
Inventor: SMITH MARTIN STEVENS
IPC: H01Q9/30
Filed: 1997-12-17
Granted: 2000-08-22
Abstract: The present invention relates to radio communications antennas and in particular relates to an antenna for such. An inverted E-shaped antenna is disclosed comprising a radiating element and a ground plane. The antenna is suitable for placement in a mobile communications handset.      The antenna finds particular applicability in dual mode handsets, where two or more antennas may be located in close proximity. The small dimensions of the antenna relative to the operating wavelength, achieved by folding back an element of the antenna, provides a simple solution to such problems as antenna coupling since its small size allows it to be placed as far away as possible within the small confines of a radio communications handset. A method of operating a mobile communications arrangement is also disclosed, the arrangement comprising a microphone, an audio speaker, a transceiver, and an antenna, wherein the antenna is in the form of an inverted E.

Abstract: On obtient des isolats de protéines ayant une forte teneur en protéines et une faible teneur résiduelle en matières grasses, sous une forme sensiblement non dénaturée, par extraction d'une farine de graines oléagineuses ayant une teneur importante en matières grasses, en particulier de la farine de colza Canola, avec une solution aqueuse de sel alimentaire pour provoquer la solubilisation des protéines et des matières grasses dans la farine de graines oléagineuses et former une solution aqueuse de protéines. Les matières grasses sont retirées de cette solution par refroidissement et élimination des matières grasses qui se séparent du reste. On accroît ainsi la concentration des protéines dans la solution dégraissée, tout en maintenant la force ionique sensiblement constante. On peut procéder, sur la solution concentrée de protéines, à une nouvelle opération d'élimination des matières grasses, suivie de la dilution donnant une force ionique inférieure à environ 0,2, afin de déclencher la formation de particules séparées de protéines dans la phase aqueuse, sous la forme de micelles de protéines. On fait en sorte que ces micelles se déposent pour former une masse d'isolat de protéines agrégées sous la forme d'une masse micellaire de protéines amorphe, gélatineuse et collante, analogue au gluten, qu'on sépare des matières qui surnagent et qu'on sèche pour obtenir une poudre protéique.

Title: Dual string backup tong
Inventor: BOULIGNY VERNON
IPC: E21B19/16
Filed: 1997-02-28
Granted: 2008-08-19
Abstract: A backup tong (1) having an inner throat (19) sized to accommodate a second pipe string while a first pipe string is held within the jaws (12, 13) of the tong is disclosed. The inventive backup tong facilitates operations on dual pipe strings by allowing the tong to grip not only the closer of two pipe strings, but also the farther of the pipe strings by allowing the nearer pipe string to reside in an inner throat of the backup tong, between the gripping members (16, 17) of the tong and the body of the backup tong, while the farther pipe string is held between the gripping members. The inventive backup tong thereby allows the operator to grip either of the pipe strings from a single side, eliminating the side-to-side movement (and corresponding time and risk of harm) which is required when using prior art backup tongs.

Abstract: A generic communications network (100) provides an encrypted communications interface between service networks (130, 132, 134) and their subscribers. When communications are initiated between a subscribing communications terminal (118) and the generic network (100), the terminal (118) compares a stored network identifier associated with a stored public key, with a unique identifier broadcast by the generic network (100). If a match is found, the terminal (118) generates a random secret key, encrypts the secret key with the stored public key, and transmits the encrypted secret key. The generic communications network (100) decrypts the secret key using a private key associated with the public key. The secret key is used thereafter by the terminal (118) and the generic network (100) to encrypt and decrypt the ensuing radio traffic. Consequently, the network (100) can maintain secure communications with the terminal (118) without ever knowing the terminal's identity.
