Abstract: Cette invention se rapporte à un procédé pour amplifier un signal d'entrée HF au moyen d'un amplificateur de puissance (105, 107 ou 205, 207), ce procédé consistant à diviser ou à séparer en quadrature (103) le signal d'entrée HF en un signal en phase et en un signal de phase en quadrature. On fait varier un signal d'entrée de polarisation d'amplificateur de porteuse (111, 211) par rapport à l'amplitude du signal d'entrée HF. On fait varier un signal d'entrée de polarisation d'amplificateur de crête (113, 213) par rapport à l'amplitude du signal d'entrée HF. Le signal en phase est amplifié au moyen d'un amplificateur de porteuse (105, 205), pour produire un premier signal amplifié. Le signal de phase en quadrature est amplifié au moyen d'un amplificateur de crête (107, 207), pour produire un second signal amplifié. Le premier signal amplifié et le second signal amplifié sont combinés (115, 117), en phase, pour produire un signal de sortie.

Abstract: Method and apparatus for detecting and/or determining ethanol in fluid samples using a substantially non-porous barrier (membrane) of un-plasticised polyvinyl chloride (PVC) interposed between the sample to be analysed and a detecting means responsive to ethanol. The ethanol diffuses through the barrier membrane and then is measured at the detecting means. The PVC membrane can be made by solvent casting, and is usually 10 to 40 νm thick. Measurement can be by any known means, but preferably electrochemically (e.g. amperometrically). The PVC membrane may be part of a multiple membrane system. The method and sensor are useful for analysis of alcoholic liquors or beverages (for example beer, wines and other fermentation products), in their final form or at intermediate stages in their manufacture or storage, and also for the monitoring of a wide range of process, waste and effluent liquids.

Title: Spiral vacuum pump
Inventor: GIGON RENE
IPC: F04C18/02
Filed: 1997-09-16
Abstract: The invention concerns a pump with spirals comprising means (29, 19, 19A) for preserving a minimum clearance between the joints (5) arranged on the ridges of each spiralling wall (27, 28, 33, 34) and the flat wall (25, 26, 31, 32) facing it. Such an arrangement, which is made possible by the low pressure difference prevailing between the two adjacent transfer chambers (50, 51), prevents the wear of the joints, the soiling of the transfer chambers as well as overheating caused by friction between the joints.

Abstract: Notches (21a, 21b) are formed at the corners of only
one side edge (19a) of a metal jacket blank (19) of a
rectangular metal strip. The blank (19) is rolled into a
cylindrical shape so that its opposite sides (19a, 19b)
are adjoined to each other forming an abutment joint (10)
and a lower end (19c) of the blank (19) is inwardly curled
and crimped to form a bottom, thus completing an outer
metal jacket (18). After a cell member (26) is loaded
into the metal jacket (18), the upper end (19d) of the
blank (19) is inwardly curled and crimped to cause the
notches (21a, 21b) to abut the other side edge (19b) of
the blank (19), forming a curled abutment joint (20) along
a direction (S) being different from the radial direction
(R) of the metal jacket (18). This arrangement prevents
any dents caused by the buckling of the outer metal jacket
(18) while being crimped, and allows dry cells to be more
efficiently produced.

Abstract: An image encoder or other image processing apparatus includes a segmentation apparatus for assigning image pixels to regions, in accordance with predetermined criteria. The segmentation apparatus provides a temporally consistent segmentation throughout a motion picture sequence, and comprises: means (102) for predicting the segmentation for a current frame (F0) upon the basis of the segmentation (S1) of the preceding frame and estimated motion vectors (M); means (104 to 106) for modifying the predicted segmentation in dependence upon the accuracy of pixel values (F0') predicted for the current frame on the basis of the motion vectors (M). In particular, for portions of the image where pixel values are not accurately predicted by the motion vectors, it is assumed that the predicted segmentation is invalid, and such portions are re-segmented and merged into the predicted segmentation to obtain the temporally consistent segmentation. In the embodiments, pixels on the borders of regions in the predicted segmentation are also considered and re-assigned to neighbouring regions according to various criteria.

Abstract: L'invention porte sur un procédé et un appareil fournissant une ressource à une armoire (100B) ou à une enceinte (100C) une ressource capable d'affecter la fabrication d'un produit. La ressource épurée est fournie à l'armoire (100B) où elle affecte la fabrication du produit lors d'une ou plusieurs phases très sensibles aux contaminants présents dans la ressource. La ressource contaminée par la fabrication du produit est ensuite envoyée dans une enceinte (100C) où elle affecte la fabrication dudit produit ou d'un autre lors de phases moins sensibles aux contaminants présents dans la ressource. Comme l'armoire (100B) est extrêmement sensible aux contaminants de la ressource, la ressource moins pure parvenant dans l'enceinte (100C) ne peut avoir d'effet adverse sur la fabrication du produit présent dans l'enceinte (100C), et il n'est donc pas nécessaire de fournir une ressource épurée à l'enceinte (100C).

Abstract: An advantageous configuration of an adsorption medium in a drying plant is described. At least one cartridge containing the adsorption medium for a gas to be dried is removably disposed in a container of the drying plant. A pressure prevails between the adsorption medium and the cartridge such that the adsorption medium remains stationary in the cartridge, in particular even under changing operating and/or environmental conditions. Using the cartridge enables the adsorption medium to be changed rapidly and safely on site. In addition, the invention ensures a high quality of gas drying, in particular without the added risk of the particles being released. Different cartridges can also be used for different adsorption media and can therefore be optimized to suit the most varied of drying plants.

Abstract: A centrifuge or other vibration-prone apparatus (20)
incorporates a detector (18) for detecting movement of the
device over a surface (44) supporting the device. The
detector comprises a ball (24) engaging the surface (44)
and supporting, by way of a laterally flexible bound-coil
spring (38), acting as a vertical strut, a plunger (34) on
the upper surface of which bear the operating levers of
microswitches (40). The ball (24) and plunger (34) are
guided for vertical sliding in a sleeve (22) supported by
the apparatus. In the event of a transverse displacement
of the apparatus, the ball (24) rolls along the supporting
surface (44), laterally displacing the lower end, bearing
on the ball (24), of the spring (34) so that it no longer
serves as a vertical strut supporting the plunger (34), and
as a result the plunger (34) drops under its weight and the
bias provided by the microswitches, so that the latter
switch off the motor of the centrifuge or like device (20).
