Une autre réalisation porte sur des compositions comprenant un vecteur d'expression incluant, sous forme exprimable, des séquences codant pour l'antigène du VPH et des séquences codant pour la protéine du stress. Le vecteur d'expression peut être introduit dans les cellules d'un sujet. Mais il peut également servir à la transduction de cellules du sujet ex vivo, ce qui aboutit à l'expression d'une protéine hybride protéine du stress - antigène du VPH qui doit normalement stimuler la réponse immunitaire du sujet à l'antigène du VPH. L'invention concerne également, non seulement des compositions comprenant une protéine du stress liée à un antigène du VPH et un autre composant pharmacologiquement acceptable, mais aussi des hybrides et des conjugués protéine du stress - antigène du VPH, et enfin des vecteurs d'expression codant pour et capable de diriger l'expression dans les cellules d'un sujet dans le cas d'une protéine hybride comprenant une protéine du stress et une séquence antigène du VPH.

Title: Image rejection sub-harmonic frequency converter realized in microstrip, particularly adapted to be used in mobile communication equipments
Inventor: POLITI MARCO
IPC: H03D9/06
Filed: 1998-09-14
Abstract: It is described an image rejection, sub-harmonic frequency converter, realized in microstrip, particularly adapted to be used in mobile communication equipment.      The converter avails of two identical sub-harmonic mixers employing each one or two pairs of diodes in antiparallel, obtained on a same silica substrate, and of a structure of hybrids performing appropriate phase combination adapted to suppress the image band in the converted signal.      The mixers include filtering structures preferably consisting, but no limited to the same, of stubs .lambda./4 long, at the local oscillator frequency, having a free end, in short or open circuit, respectively. According to an alternative embodiment, said stubs are replaced by appropriate filter, implemented with concentrated structures (L and C) performing the same transfer function of the stubs in microstrip. The sub-harmonic converter and a traditional converter can be jointly employed in a terminal mobile equipment operating in "Dual Mode service hand-held" (GSM 900 and DCS 1800) sharing a unique 900 MHz local oscillator.
Patent CA-2307817-A1 (CA)
Inventor: GROTHE HORST
IPC: B22D11/128
Filed: 2000-05-08
Abstract: In a method and a device for manufacturing continuous cast steel products, a cast strand of steel having a liquid core when leaving the casting die is cast by continuous casting. The liquid core of the cast strand is deformed by guiding the cast strand through a deforming gap of a deforming roller pair. In the deforming step, the strand removal force is determined as an actual value, wherein the strand removal force results from a set adjusting force of the roller pair, a deformation thickness of the cast strand, and a material parameter. The actual value is compared to a set value defined as a removal force resulting when the liquid core tip is precisely positioned in the deforming gap. Based on a deviation of the actual value and the set value, the relative position between the liquid core tip and the deforming gap is adjusted such that completion of solidification occurs directly within the deforming gap.

Title: Method and apparatus for performing handoff in a cdma system through the use of repeaters
Inventor: BAKER KENNETH R
IPC: H04B7/26
Filed: 1998-11-25
Abstract: A method and apparatus for providing handoff between two communication systems. The systems can be CDMA systems operating at different frequencies or systems employing different technologies. In the first system, a base station (4) is configured to provide communications to two or more sectors, with at least one sector assigned to a corresponding repeater (8) which provides coverage overlapping that of both systems. As the remote station (6) moves into the coverage area of the repeater (8), the pilot signal of the repeater (8) is identified, measured and sent to the first system. If the measured pilot signal is above a predetermined add threshold, the repeater (8) is added to the active set of the remote station. The first system can handoff the remote station (6) to the second system: (1) upon initiation of a soft handoff by the base station of the first system; (2) if the pilot signal strength of the repeater (8), as measured by the remote station (6), exceeds a predetermined handoff threshold; (3) if the base station (4) of the first system is dropped from the active set of the remote station (6); (4) if the repeater of the first system is dropped from the active set of the remote station (6); or (5) if the base station (4) and repeater (8) of the first system are dropped from the active set of the remote station (6).

Title: Electric steering column
Inventor: WARASHINA TOSHIHIKO
IPC: B62D1/181
Filed: 2000-06-22
Abstract: An electric steering column for a motor vehicle is provided, which has a steering shaft. A jacket tube extends along the steering shaft to cover the same. A worm wheel is rotatably held by the jacket tube and has a center bore through which a given portion of the steering shaft loosely passes. A collar member is tightly disposed on the given portion of the steering shaft defining an annular clearance between the collar member and the worm wheel. An elastically deformable structure is put and compressed in the annular clearance in such a manner as to induce a rotation of the collar member when the worm wheel is rotated. An electric motor rotates the worm wheel with an electric power. Due to provision of the elastically deformable structure, a possible ill-alignment between the worm wheel and the collar member is absorbed or compensated.

Title: Oiless rotary scroll air compressor antirotation lubrication mechanism
Inventor: JONES CHARLIE E
IPC: F04C18/02
Filed: 2000-11-17
Abstract: A lubrication apparatus for an anti-rotation assembly of an oiless rotary scroll compressor is disclosed. The scroll compressor includes a stationary scroll element and an orbiting scroll element which orbits about the stationary scroll element in a non-rotational fashion. At least one anti-rotation assembly is provided for preventing relative rotation between the orbiting and stationary scroll elements. The anti-rotation assembly, which includes a first rotational bearing component mounted on the interior of the housing, a second rotational bearing component mounted on the orbiting scroll element and an offset crank member interconnecting the first and second rotational bearing components, is lubricated via a lubrication channel. The lubrication channel extends from a lubrication port disposed on the exterior of the housing, through the first rotational bearing component, thereafter through a channel provided in the offset crank member, thus allowing the lubricating agent (e. g., grease) to reach the second rotational bearing component. The provided anti-rotation assembly can thus be periodically lubricated without significant contact between the lubricating agent and the gas being compressed (e. g., air or refrigerant). Accordingly, any possible contamination of the exiting compressed gas is significantly reduced.
