Patent EP-0110959-A4 (EP)
Title: Electric fluid flow heater having precise temperature control.
Inventor: LEHRKE KENNETH E
IPC: F24H1/12
Filed: 1983-05-16
Abstract: An electric fluid flow heating apparatus for heating of paints, lacquers, varnishes and other coating materials in industrial coating operations to control viscosity of a coating material being applied by a spraying apparatus utilizes a pair of low mass electric resistance heating elements (14) located within the legs of a U-shaped fluid flow passageway defining hollow tube (10) havig an inlet manifold (16) and an outlet manifold (18). A fluid mixer (12), formed as a helical metallic spring member having diametrically opposed, axially extending baffles (32) projecting inwardly from the outer diameter of the helical member surrounds each heating element (14) and causes the flow of liquid to follow a generally helical path directed radially inwardly at the baffles (32), to produce continuous mixing of the liquid. Overtemperature safety switch (26) is attached to the outside of the tube (10). The outlet manifold (18) mounts a temperature probe (25) having a thermistor (34) embedded in a conical housing (36) projecting into the fluid flow path and contacting the heating element (14). A proportional-control, slope compensated, electronic temperature control circuit monitors temperature conditions across the flow path sensed by the temperature probe (25) as well as the ambient workplace temperature sensed by an ambient temperature compensator (R3) and regulates the output of the heating elements (14) to provide precise temperature control under varying static and dynamic liquid flow conditions and changing ambient workplace temperature conditions. The control circuit reduces the watt density of the heating elements (14) under conditions of complete static flow to prevent development of excessive liquid temperature.
Patent EP-0111538-A4 (EP)
Inventor: PRICE EDWIN A
IPC: F28D20/00
Filed: 1983-05-13
Abstract: Echangeur thermique du type à ailettes à rendement élevé (A), pouvant être facilement reproduit, s'appliquant à de nombreuses utilisations, présentant de faibles coûts de production, un volume relativement compact ainsi qu'un faible poids. La construction permet d'obtenir une faible résistance à un milieu en écoulement, grâce à l'utilisation d'un réseau d'ailettes très thermo-conductrices (3, 26), chaque ailette (3) faisant saillie dans une pièce continue, au travers d'une séparation (1, 23) de plus faible conductivité thermique qui sépare deux milieux. L'intersection est fermée hermétiquement, de manière à empêcher la transcontamination entre les deux milieux. Une capacité élevée d'échange thermique est obtenue par une configuration dans laquelle le milieu en écoulement entre en contact de manière répétitive avec le réseau d'ailettes très thermo-conductrices (3), lesquelles ailettes extraient la chaleur contenue dans le milieu et véhiculent cette chaleur au travers de la cloison de séparation (1, 23) dans le deuxième milieu. Le dispositif et le procédé présentent une utilité particulière dans un certain nombre d'applications, telles que: la récupération de la chaleur perdue (Fig. 1-6, 9 et 12); des dispositifs de chauffage d'eau (Fig. 8); une combinaison de pot d'échappement et de dispositif de chauffage (Fig. 10); des tubes de terre (Fig. 7); des systèmes de transfert d'énergie solaire (non illutrés); ou nombreuses applications de dissipation thermique, où les ailettes (3, 26) sont soit noyées dans un organe conducteur (Figs. 13 et 14) soit elles font saillie au travers d'un organe conducteur plus petit (23, 28, 29) (Fig. 11), et s'étendent vers l'extérieur dans l'atmosphère ambiante.

Patent EP-0145750-A4 (EP)
Title: Methods for decontaminating soil.
Inventor: PETERSON ROBERT L
IPC: D06M16/00
Filed: 1984-05-25
Abstract: A reagent mixture is admixed with soil to first desorb and then hydrolyze and thereby increase the biodegradability of a toxic or otherwise hazardous polyhalogenated organic compound with which the soil is contaminated. Essential constituents of the reagent mixture are: (1) an alkali metal hydroxide, an alkali metal hydroxide/alcohol or alkali metal hyroxide/glycol mixture, or an alkoxide; and (2) a sulfoxide catalyst. The hydrolyzed compounds can be biologically degraded into compounds which pose little if any hazard to the environment or its inhabitants by naturally occurring or artifically introduced Pseudomonas sp. and other microorganisms with adjustment of soil pH (and perhaps orther parameters) to provide a viable environment for the bacteria being carried out after the chemical treatment if inoculation with bacterial cultures is employed. If a mixture of non-biodegradable and biodegradable contaminants is present, a preliminary biodegradation step can be optionally used to rid the contaminated area of the latter before hydrolysis of the contaminated soil with the reagent mixture is undertaken.

Title: Photoresist stripper composition.
Inventor: MARTIN THEODORE A JR
IPC: C11D7/50
Filed: 1987-09-10
Abstract: A photoresist stripper composition comprises a mixture of (a) pyrrolidone, N-substituted pyrrolidones, butyrolactone or caprolactone as the major component and (b) from about 2 to about 10 percent by weight of a tetraalkylammonium hydroxide or a trialkylaralkylammonium hydroxide. Optional components of the mixture include surfactants, diluents and metal corrosion inhibitors. Extraneously added water is avoided.

Patent EP-0331749-A4 (EP)
IPC: G05D13/62
Filed: 1988-09-09
Abstract: Lorsqu'un mandrin principal (10) est mis en rotation et que le mandrin principal et une pièce à usiner se déplacent selon un mouvement linéaire et selon un mouvement relatif l'un par rapport à l'autre dans la direction axiale (Z) du mandrin principal, par exemple lors de l'opération de filetage d'une machine-outil, un servomoteur de mandrin (12) et un servomoteur d'avance (22) qui servent de source d'entraînement doivent être actionnés pendant que s'effectue leur synchronisation. Généralement, le servomoteur de mandrin entraîne directement le mandrin principal sans recourir à un engrenage de réduction, mais le servomoteur d'avance entraîne une tête de mandrin principal (18) par l'intermédiaire d'engrenages de réduction (26, 28). Par conséquent, la synchronisation est généralement gouvernée par la performance d'accélération/décélération du servomoteur de mandrin. La synchronisation peut être obtenue avec une efficacité maximum grâce à l'accélération et à la décélération du mandrin principal, pendant que le servomoteur de mandrin est actionné en ligne avec ses courbes de limite de couple (L1, L2).

Patent EP-0473717-A4 (EP)
Title: Dispensing closure
IPC: B65D47/26
Filed: 1990-05-22
Abstract: A dispensing closure having a base ring with means for attachment to a container which permits rotation of the ring without axial movement. A lid is connected to the base ring by a hinge which allows the lid to be swung from a closed position blocking access to a container opening to an open dispensing position. A cam element on the lid effects initial movement of the lid towards an open position when the base ring is rotated. The lid cam element cooperates with a cam surface on the container. A fitment can also be used to attach the closure to a flat can top or to other container configurations. When a fitment is used, the cam surface will be on the fitment rather than the container.

Un paquet de commande de multiplexage, produit (104) pour chaque champ, précise pour chaque service quelle portion de la région de données de service est attribuée audit service. Un plan de multiplexage (104) est émis avec chaque champ, ce qui permet de moduler de façon dynamique le nombre et la position des paquets champ par champ.
