Patent EP-0897414-A1 (EP)
Inventor: AMICHE FREDERIC
IPC: C09D7/61
Filed: 1997-04-22
Abstract: The invention discloses a method for preparing hollow particles comprising a dense silica core, by precipitating active silica from an aqueous alkaline metal silicate on a core constituted in a material other than silica and by elimination of the material without destroying the silica shell. The said particles are used as insulating materials, as hollow fillers for polymers, building materials, rubber, paper, paint, as abosrbing agents, as toothpaste abrasives or additives, as support for the absorption and/or graining out active matter, the liberation of the said active matter being effected by the destruction of the silica core by mechanical rupture or by dissolving the silica shell in a basic medium or by diffusion, as sun screening agents or sun screening agent supports or for the formulation of liquid matter in solid form.

Abstract: L'invention concerne un circuit d'amplificateurs à pont comprenant deux amplificateurs dans une configuration en pont comportant une voie de rétroaction connectée à la sortie d'un des amplificateur et à l'entrée de référence de l'autre amplificateur. Des moyens de compensation sont également fournis afin de réduire les variations de tension au niveau de l'entrée de référence. Ce procédé réduit le décalage et la distorsion, bien que le gain du circuit d'amplification ne soit pas affecté par la présence de la voie de rétroaction.

Title: Article a systeme de revetement protecteur comprenant une couche d'ancrage perfectionnee, et sa fabrication
Inventor: BEELE WOLFRAM
IPC: C23C28/04
Filed: 1997-06-02
Abstract: On obtient un nouvel article fabriqué en recouvrant un substrat composé d'un superalliage à base de nickel ou de cobalt d'un système protecteur résistant aux attaques thermiques, de corrosion et d'érosion. Une couche de liaison est disposée sur le substrat et une couche d'ancrage sur la couche de liaison. La couche d'ancrage est constituée par un composé de nitrure, plus particulièrement de nitrure d'aluminium. Un revêtement en céramique est disposé sur la couche d'ancrage. Celle-ci prévient la transmission d'éléments à activité de diffusion à travers la couche d'ancrage jusqu'à la couche barrière thermique, réduit l'oxydation des couches sous-jacentes et assure une bonne transmission de chaleur à travers ladite couche.

Abstract: L'invention porte sur l'utilisation de la magnétohydrodynamique (MHD) dans le but spécifique de détruire des populations de micro-organismes dans des matériaux traversant un passage ou une cellule statique. La cellule MHD (16) comporte un passage de confinement de liquides (48) muni d'électrodes (50, 52) placées entre les pôles d'un aimant (42) avec un décalage de phase de 90° avec eux. Un courant est envoyé transversalement dans le liquide, à angle droit avec les parties en mouvement autres que le liquide lui-même. Les champs électrique et magnétique croisés produisent des déplacements d'ions atteignant ou dépassant la vitesse des ions dans l'eau bouillante. Dans un système de stérilisation par MHD à flux traversant (10) le matériau passe devant un transducteur (12) tandis qu'un conduit de matériau conducteur régule le flux en fonction de la capacité de stérilisation effective du système. D'autre part, l'ordinateur (20) du système donne l'instruction à l'alimentation réglable la tension correcte de fournir aux bornes des l'électrodes (50, 52) de la cellule MHD. L'invention porte également sur un système statique de stérilisation (60) par MHD dans lequel le passage traversant la cellule MHD (62) est fermé à l'une de ses extrémités.

Abstract: When a processing unit of a vector computer
detects an optimization directive line for optimizing
a list accessing method during the compilation, an
access method is automatically changed according to
an instruction of the directive line. For example,
data to be accessed are copied to a work array, the
access order is changed at random, and a scalar load
process is performed. As a result, high-speed list
access can be realized without a bank conflict at a
vectorization.

Abstract: A regulator (300) has an output transistor (310) which transfers an input (391) to
an output (305) wherein the output current I OUT  at the output (305) is limited. A driver
portion (311) for controlling the output transistor (310) comprises a mirror transistor
(380) coupled to the output transistor (310), a resistor (330) which carries a scaled
replica (I CL ) of the output current (I OUT ), and a transistor chain (335) which transfers a
potential (V CL ) at the resistor (330) to an input node (351) at a control input (394) and
which transfers a control signal (V IN ) from the control input (394) to the output
transistor (310). The potential (V CL ) at the resistor (330) corresponds to the output
current (I OUT ). An increase of the input node potential (V X ) is limited by a clamping
transistor (352) at the input node (351). A rise of the output current (I OUT ) is
communicated to the input node (351) by the chain (335). Since a further increase of
the input node potential (V X ) is prevented by the clamping transistor (352), the driver
portion (311) does allow the output transistor (310) to drain current only below or at a
predetermined maximum (I OUT MAX ).

Abstract: There is provided a transient electromagnetic method
and apparatus for inspecting objects using a moving sensor.
The apparatus (13) includes a sensing portion (27) which
has a transmitting antenna (29) and at least one receiving
antenna thereon (31). The sensing portion (27) is located
adjacent to the object which is to be inspected such that
the antennas (29,31) are adjacent to the object. The
sensing portion (27) is moved along the object at the same
time as the transmitting antenna (29) is inducing current
in the wall and the receiving antenna (31) is producing a
receiving signal of the induced current diffusion in the
wall. Because the antennas (29,31) are moving during data
acquisition, the speed of inspection is increased. The
data is then interpreted to determine the thickness of the
object.
