La présente invention concerne une porte ou paroi d'enceinte climatique et en particulier une porte ou paroi vitrée. Selon l'invention, la porte ou paroi est constituée essentiellement d'un panneau isolant composé d'au moins deux substrats en verre entre lesquels un vide a été réalisé, séparés l'un de l'autre par des plots répartis sur toute la surface et réunis à leur périphérie par un joint de s...

A system and method for displaying MPEG-2 packets as a hierarchy of tables within a window of a graphical display. This hierarchial display is updated continuously as new packets are received, thus providing a real time display. When a packet is received, and the location of that packet has not been identified, the packet is placed at the top of the hierarchy. Once a subsequent packet is received ...

Routines for manipulating data in a database are performed by a database server by determining whether or not a database manipulation routine is to be isolated from a specified range of memory, and, in response, selectively switching memory access permission to the specified range of memory (e.g., from read/write to read-only) for the database manipulation routine under consideration. The database...

Une installation de séparation d'un mélange gazeux comprend au moins deux colonnes (1, 3, 5) ayant la même hauteur. Les têtes de deux des colonnes sont à la même hauteur.; Cryogenic distillation plant for separating gas mixtures comprises two or more upright distillation columns, of which at least two have their top ends on one level and at least two are of equal height.

The invention relates to a spinal disc endoprosthesis. The endoprosthesis has a resilient body formed of one or more materials which may vary in stiffness from a relative ly stiff exterior annular gasket portion to a relatively supple central nucleus portion. Concavalconvex elements at least partly surround that nucleus portion so as to retain the nucleus portio n and gasket between adjacent verte...

This invention relates to a pillow (1) and a mattress (6) the anatomical shape a nd rigidity of which help to combat pathological lordosis of the forward convex cur vature particular to the cervical region and spondylitis in the dorsal region of the ve rtical column. The pillow (1) consists of two rounded lobes (2) and (3) with an anatomical shap e for resting the head when the body is lying down ...

The present invention relates to a high density tethered polymer surface materia l comprising two regions: (1) a polymer shell characterized by an optimal surface concentrati on of aldehyde, hydroxyl or sulfhydryl groups; and (2) polymer chains tethered to the shell via the surface groups. The chains function to exclude biomolecules and polymers from ap proaching the polymer core, thereby minimizi...

Shingling of paperboard sheets cut from a web with a helical blade cutoff knife utilizes the downward deflection of the trailing edge of the cut sheet and simultaneous lifting of the leading edge of the web to position the sheets for shingling immediately downstream of the knife. A vacuum outfeed conveyor takes advantage of the initial downward deflection of the sheet caused by cutting to pull the...

Rolling method for thin flat products, used in the production of flat rolled products with a final thickness in the range of 0.6 DIVIDED 1.5 mm or more, up to 2.0 DIVIDED 3.0 mm, in a plant suitable to work thicknesses of up to 25.4 mm, the method being applied to slabs with a thickness of between 50 and 90 mm if arriving directly from the continuous casting machine or on slabs with a greater thic...

A system is provided for controlling a D-C motor which is constructed to propel a golf car. The motor is controlled to provide performance according to a predetermined field current map which calls for a particular performance response to specified performance events. The performance events are detected by sensing actual speed and armature current and the performance response is triggered by adjus...

The present invention relates to a method, and the product thereof, of reducing one or more metal centres of one or more organometallic precursors in the presence of a metal surface to deposit sub-monolayer, monolayer or multilayer quantities of the metal centres thereon. Further, the invention relates to a method, and the product thereof, of hydrogenating an organometallic precursor over a metal ...

A current collector includes a thin porous substrate and a hydrophilic material, where the hydrophilic material is provided to holes of the thin porous substrate or surfaces of skeleton elements of the porous substrate so that hydrophilic areas formed. by the hydrophilic material successively pass through the thin porous substrate between both surfaces of the thin porous substrate. In the current ...

Patch, comportant une couche de polymère hydrophobe, fixée sur une couche support et contenant: a) des premières particules d'au moins un composé actif hydrosoluble, b) des deuxièmes particules d'huile, c) au moins un composé actif liposoluble. La couche de polymère contient, en outre, des troisièmes particules d'un agent hydro-absorbant, dispersées de façon homogène dans la couche de polymère. Ce...

A magnetic bearing system must rely on position feedback information for control . Position signal noise degrades performance of the magnetic bearing control and avoidance of the introduction of noise can result in increased controller perfor mance. A digitally controlled magnetic bearing system requires anti-alias filtering on al l sampled channels to attenuate noise above the Nyquist rate to a l...

A magnetic bearing control system may require rotational sensor information for data acquisition and/or control purposes. The scheme presented provides a method to reliably input such rotational sensor information without the need for user inte rvention.

Active magnetic bearings are used to suspend shafts of rotating equipment subjec t to load spectra which vary with respect to time. Control of the position of the rotating assemblies of such equipment is effected by electromechanical systems which combine the use of feedback control to switching amplifiers. The output of these amplifiers must vary of the order of thousands of cycles per second in ...

The strips are applied to a variety of surfaces in order to provide a distinct relief pattern by spraying a liquid through an oval nozzle at right angles to the surface. The distance between the nozzle and surface is controlled to ensure the distance between nozzle and surface divided by the required strip width is equal to 3.2 plus or minus 1.
