Title: Resource capacity reporting to control node of radio access network
Inventor: BROUWER FRANK
IPC: H04W24/02
Filed: 2001-10-05
Abstract: A base station node ( 28 ) of a radio access network determines a number of connections that can be added for each of plural spreading factors to the base station node, and sends to a radio network controller (RNC) node ( 26 ) a capacity indication ( 110 ) including the determined number of connections. In a first message mode of the invention, the capacity indication is included in a conventional 3GPP "Resource Status Indication" message, while in a second message mode the capacity indication is included in a separate supplemental message known as the capacity message. To prepare the capacity indication, the base station tracks actual usage of base station resources for determining the number of connections that can be added to the base station node, and assesses the capability of the base station node to add new connections.

Title: Elimination des dechets dans la fabrication de papier
Inventor: HEINZEL GUNTER
IPC: C02F9/00
Filed: 1996-05-02
Abstract: La présente invention concerne un agent destiné à extraire les contaminants de l'eau utilisée dans la fabrication du papier et de produits connexes, de la formule générale (ZO)nAln(OH)n-mClm (ou d'une formule empirique très proche de celle-ci), dans laquelle Z est dérivé d'une matière d'alumino-silicate, ledit agent ayant été éventuellement recouvert de polymère. L'agent est préparé de la façon suivante: on active la matière d'alumino-silicate en la traitant avec de l'acide ou en la soumettant à un échange d'ions ammonium, et on chauffe ensuite la matière ainsi activée en présence d'un agent cationique, pour la revêtir d'un polymère. L'alumino-silicate préféré est un minéral contenant de la zéolite d'une structure de clinoptilolite et l'agent cationique préféré est sélectionné parmi un polyaluminiumchlorure, une épichlorhydrine (ou un dérivatif polymère de celle-ci) ou un dicyanodiamide. Le polymère de revêtement préféré est un polyacrylamide. L'utilisation de cet agent entraîne une augmentation de la production et une réduction à la fois de la formation de boues, de la charge de contaminants, des besoins en oxygène chimique, ce qui est source d'économies.

Patent CA-2000672-A1 (CA)
IPC: F41G7/32
Filed: 1989-10-13
Abstract: ABSTRACT      A fiberoptic leader (20) connected between a missile (10) and a launch tube is paid out upon missile launch with a controlled degree of bend in the fiberoptic fila-ment (50), and is furthermore protected from blast effects in the launch.  The fiberoptic filament (50) is stiffened within a leader (30) comprised of a TEFLON sleeve (52) insulating the fiberoptic filament (50).  A protective sheathing of high tensile strength longitudinally wires (54) are disposed about and encase the TEFLONTM sleeve (52), and in turn are encased within an outer sleeve.  The stif-fened leader is led along the longitudinal length of a retainer (20) attached to the side of the missile. The retainer (20) is disposed upon a longitudinal portion of the missile in a channel.  The stiffened leader (20) is laid against and under one of the retainer arms from the aft end of the missile (10), where the fiberoptic leader (30) is fed out during launch, to a forward end of the missile (10) and retainer (20).  The leader (30) is then led across the width of the channel to the opposing arm of the channel.  The stiffened leader (30) is then led partly aft along the opposing arm of the retainer (20) and then out to an open longitudinal slot defining the ends of the channel and is coupled to a fixed point within the launch tube from which point optical communications are provided to the missile (10) during flight.  As the missile (10) is launched, the bend propagates down the retainer (20) tear-ing the stiffened leader from a longitudinally perforated tape which secures the leader (30) into and under one of the arms of the retainer (20).

Abstract: Abstract A steering roller arrangement for a three-wheeled vehicle A steering roller arrangement  for a trackless  floor vehicle in the form of a so-called three-wheeled vehicle is described. With this vehicle,  in addition to two running wheels, a steering roller is provided which can be swiveled about a vertical axis by means of a ring mount for traveling in a curved line and to achieve a trailing effect. Relative to the rotatable part of the ring mount, the steering roller is movable between two opposite trailing positions such that, with a reversal of the direction of travel, the required alteration of the steering roller trailing effect is brought about by a corresponding adjustment of the steering roller. In this way uncontrolled veering of the vehicle is avoided which occur with conventional three-wheeled vehicles on account of the rotation of the steering roller by 180° caused by the trailing effect of the steering roller. The steering roller is expediently displaceable in a straight line by a linear guide between the two trailing posi-tions. The linear guide can serve at the same time as a self-aligning bearing, by means of which the steering roller can be tilted about a horizontal axis to adapt to unevenness in the floor.

Abstract: Highly immunoreactive regions of gp41 of HIV-1, gp32 of HIV-2 and p24 of HIV-1 were identified using synthetic peptides. Superior immunoassay performance is obtained with these peptides linked to carrier proteins as compared to use of the free peptides. Additional natural and unnatural variants of these reactive regions to define a set of peptides that, as cysteine-linked peptide-protein conjugates, provide optimal immunoassay performance including high immunoreactivity with HIV antibody positive samples, low reactivity with negative samples, high discrimination between positives and negatives, and high specificity. These peptide conjugates further permit simultaneous detection of HIV-1 and HIV-2 antibodies, and make possible rapid and simple test formats that require no instrumentation for detection of these antibodies.
