Abstract: L'invention concerne un procédé pour préparer des vaccins polyvalents à protéosomes-déterminants amphiphiles, convenant à une administration parentérale ou mucosale par diafiltration ou ultrafiltration. Les déterminants amphiphiles comprennent des lipopolysaccharides de bactéries Gram négatif, par exemple de S. flexneri, P. shigelloides et S. sonnei. Les protéosomes sont obtenus à partir des méningocoques du type 2b du groupe B. Les complexes protéosomes actifs-déterminants amphiphiles (complexes non covalents) du vaccin sont obtenus par diafiltration ou par ultrafiltration, pour éliminer le détergent. L'utilisation de la diafiltration ou de l'ultrafiltration diminue le temps de traitement et les risques de contamination. Egalement, on peut travailler à température ambiante et on peut facilement augmenter la taille des installations. En plus, le procédé permet une surveillance continue et sûre du dialysat, ce qui améliore l'efficacité de tout le procédé. La durée de la dialyse pour la production d'un lot de vaccin passe de plus de 7-10 jours à moins de 72 heures et habituellement moins de 48 ou 24 heures. L'utilisation du procédé optimise la présence de chaque composant antigénique dans la préparation de vaccins polyvalents.

Title: Large round baler having wrapping mechanism for placing net over edges of bale
Inventor: LEIBER YUVAL
IPC: A01F15/07
Filed: 1998-09-08
Granted: 2002-02-26
Abstract: A large round baler includes a net wrapping device mounted to the rear and bottom of the discharge gate of the baler. A spare roll of net material is stored above an active roll of net material which rests upon and is caused to be rotated by the upper roll of a pair of net material feed rolls. The rolls of material are wider than the baling chamber of the baler and net spreader rolls, including both raised spirals and spiral grooves, are provided along the net feed path so that the net is at its full width when it arrives at the inlet to the bale chamber which is located at a lower bale-forming belt support roll extending between opposite sidewalls of the gate at the lower front of the gate. A pair of guide plates are mounted to the insides of the bale chamber sidewalls and extend about an upper portion of the circumference of a net spreader rolls located at the opposite ends of the belt support roll. These guide plates are shaped and positioned such that they perform the functions of creating a space between the bale end and the side wall for receiving marginal portions of the net, defining together with the side walls, a channel which leads from the net spreader rolls to the space created for receiving the net, rounding the end edges of the bale for better reception of the marginal portions of the net and deflecting crop material away from the spirals of the net spreader rolls so as to prevent them from wrapping with crop which would interfere with the feeding of the marginal portions of the net to be placed over the edges or corners at the opposite ends of the bale. First and second alternate embodiments respectively have only the recess or the entire shape of inner surfaces of the guide plates formed into the sidewalls. In the latter case, openings are provided in the sidewalls adjacent the trailing part of the formed shape, as considered relative to the direction of rotation of a bale engaging the formed shape.

Title: Method of and apparatus for interference rejection combining and downlink beamforming in a cellular radiocommunications system
Inventor: OSTMAN THOMAS
IPC: H04L25/08
Filed: 1997-05-27
Granted: 2006-02-21
Abstract: Recently, interference rejection combining techniques have been proposed which can increase significantly the performance of the uplink in C/I limited environments.      Another interesting property of the IRC techniques is that their C/I performance does not degrade as the correlation between the received signals increases. This feature of IRC techniques is exploited in the present invention to allow for a reduced spacing between the antennas. According to another aspect of the present invention, the performance of the downlink is improved using beamforming techniques to "steer" base station transmissions toward a desired mobile station.      In this way, the performance of the downlink is improved using beamforming techniques to a degree similar to that at which the uplink has been improved using IRC techniques.      This allows the system designer to more fully exploit the variations in system design associated with improving the uplink performance.

Abstract: L'invention porte sur un nouveau procédé et une nouvelle structure pour amorcer par contact un chalumeau à plasma. Un composant électroconducteur ou un anneau de turbulence est mis en contact avec une électrode par un élément élastique à ressorts. On crée un arc pilote en faisant circuler du courant dans l'interface électrode/composant. Puis le composant se translate sous l'influence de la pression du gaz dans la chambre à plasma formée entre l'électrode et le composant, ce qui comprime l'élément élastique et amorce l'arc pilote. L'élément à ressorts peut faire partie de la buse, de l'anneau à tourbillons ou du bouchon de retenue, ce qui facilite la dépose et le remplacement de l'élément à ressorts avec les éléments consommables du chalumeau. Les ressorts utilisables peuvent être par exemple du type à rondelles ondulées, à rondelles à doigts, à rondelles courbes, à boudin comprimé, à fils plats comprimés ou à diaphragme.

Title: Counterpulsation device using noncompressed air
Inventor: SHABTY PAUL
IPC: G05B15/02
Filed: 1998-08-13
Granted: 2009-06-02
Abstract: A counterpulsation device that operates without the use of compressed air or pressurized gas includes at least one inflatable cuff that is adapted to be placed about a selected portion of the patient's body. A conduit connects the inflatable cuff to an air transfer device so that noncompressed air can be transferred from the air transfer device to th e cuff through the conduit to inflate the cuff. The conduit also connects the cuff to the air transfer device so that air can flow through th e conduit to deflate the cuff. Another conduit is coupled to the first so that the air in the system can be selectively vented into the atmosphere. A series of valves are placed on the conduit to selectively control whether air is supplied to or withdrawn from the inflatable cuff. Th e air moving device preferably is a cylinder having a piston that moves through the cylinder to move the air from within the cylinder through the conduit and into or out of the cuff as desired. The piston moves through the cylinder through the use of a linear servo actuator that is controlled by an appropriately programmed electronic controller so that the inflation of the cuff is timed with portions of the patient's EKG signal and peripheral plethysmographic wave.

Title: Laser beam adjustment
Inventor: HOLLANDER MILTON BERNARD
IPC: G02B23/04
Filed: 2000-09-15
Granted: 2012-03-13
Abstract: The invention relates to instruments, such as radiometers, which generate a laser beam for striking a target at a distance to assist in aiming the instrument at a selected area of a target. Provision is made for splitting a single beam, used for instance for centering the instrument on the target, into a plurality of beams for creating a pattern or for defining an area on the target. When a single beam is split, the resultant plural beams produced are of relatively lower power, which may be insufficient for visibility on a target at a distance. The beam splitting apparatus may be an attachment releasably engaged on the instrument, the attachment having a body structure with a relatively movable carrier incorporating a beam splitter device. Relative movement of the carrier serves to actuate switching means controlling the power of the laser beam.
