Patent EP-0637128-A1 (EP)
Inventor: VORENKAMP PIETER C O INT OCTRO
IPC: H03F3/45
Filed: 1994-07-21
Abstract: A differential voltage-current converter has two input transistors (T1, T2) and two cross-coupled transistors (T3, T4) arranged in a translinear loop, the difference voltage across the emitter resistors (10, 12) of the cross-coupled transistors (T3, T4) being equal to the difference voltage across the input terminals (2, 4). The difference current through the cross-coupled transistors (T3, T4) is replicated in the output transistors (T5, T6), thereby enabling a larger output signal amplitude to be obtained. In order to increase the permissible input voltage the bases of the cross-coupled transistors (T3, T4) are coupled to the input transistors (T1, T2)  via  emitter-followers (T7 ,T8). By connecting the collectors of the emitter-followers (T7, T8) to the collectors of the output transistors (T5, T6) a compensation is obtained for the decreasing current gain at high frequencies.

Abstract: A box corner forming apparatus (10) is disclosed for forming non-rectangular corners on cigarette boxes (27) and the like. A plurality of wedge-shaped spacers (14, 16) defining a plurality of parallel-sided pockets (12) are arranged around a drying drum carousel (10) for receiving opposed walls of a partly formed box having projecting side flaps (44E). A pair of folding plates (42) are provided for folding down the side flaps along corner formations defined by parallel striations (45A) between the opposed walls and the side flaps so as to form corners (44F). Corner support means in the form of a pair of retractible wedge-shaped cheek plates (28, 28A) are mounted slidably on opposite sides of the corresponding wedge-shaped spacers for supporting and maintaining the shape of the corner as it is being formed. The invention extends to a method of forming rounded or chamfered corners for a box.

Abstract: Therefore, according to the present invention, one or more bond pads of a memory device are connected to a corresponding address buffer or address buffers by a selection circuit which selectively allows the address buffer to ignore a signal on the bond pad. In order to define a smaller density memory device, the signal on the bond pad is ignored, and the selection circuit internally forces a logic state on the address buffer which points to the desired smaller density memory device. The memory devices and the smaller density memory devices are packaged and bonded identically and then sorted and branded such that it is not necessary to use the double inking technique. The present invention may be applied to a plurality of bond pads and corresponding address buffers. According to a preferred embodiment of the invention, the selection circuit is comprised of a plurality of fuses which may be selectively blown to cause the address buffer to ignore a signal on the bond pad. Nonvolatile devices such as EPROM, EEPROM, Flash EPROM or PROM devices may also be used instead of fuses. The present invention can make use of ESD transistors or nonvolatile devices and fuses.

Abstract: Afin d'obtenir un support de catalyseur ayant un corps de support perméable aux gaz et une couche superficielle poreuse contenant une proportion élevée d'acide silicique, et qui soit résistant aux hautes températures et aux acides, sans qu'il soit nécessaire d'appliquer une couche lavis, le corps de support et la couche superficielle forment une structure chimiquement et physiquement homogène façonnée en une seule opération dont la teneur en SiO2 s'élève à au moins 99 % en poids et qui a une surface spécifique comprise entre 5 m2/g et 50 m2/g. Selon un procédé de fabrication d'un support de catalyseur en particules synthétiques amorphes d'acide silicique contenant plus de 99 % en poids de SiO2, on forme une pâte plastique avec les particules d'acide silicique, en les mélangeant à un liquide et à un liant, et on forme avec la pâte un compact vert, qui est ensuite fritté. Afin d'obtenir un procédé économique en continu, on ajoute à la pâte des agents plastifiants, on extrude la pâte en un boudin vert monolithique, on ajuste la teneur en alcali et en bases alcalino-terreuses de la pâte de sorte qu'elle ne dépasse pas 200 ppm et on fritte le compact vert à une température comprise entre 800 °C et 1400 °C.

Abstract: Described is a method for determining the potency of bovine somatrotopin. The level of biologically active bovine somatotropin protein in the bovine somatotropin sample is measured by size exclusion HPLC employing as the stationary phase a hydrophilic porous polymer gel having an average particle diameter of about 5 νm to about 15 νm and as a mobile phase a buffered aqueous solution having a pH of about 8 to about 12 and which is non-denaturing to the boving somatotropin sample. The potency of the bovine somatotropin sample is determined based upon the level of biologically active bovine somatotropin protein so measured. The method provides an expedient, precise and accurate measure of the potency of a bST sample.

Title: Composition de mousse et procede iteratif d'utilisation de cette mousse pour le traitement de puits
Inventor: THOMAS TODD R
IPC: C09K8/38
Filed: 1994-01-14
Abstract: Au cours de l'enlèvement de matières particulaires d'un puits de forage, tel que le forage pneumatique permettant la récupération d'hydrocarbures, un mélange d'un agent moussant amphotère et, généralement, d'un agent tensioactif anionique est utilisé. Une solution aqueuse de ce mélange, présentant un pH d'au moins 9,5, est utilisée pour générer une mousse permettant d'enlever les matières particulaires; la mousse est ensuite affaissée par l'introduction d'un acide afin de réduire le pH à une valeur inférieure à 4, les particules sont mécaniquement enlevées, le pH est ramené à une valeur supérieure à 9,5, et la solution moussante est réintroduite dans le puits. Cette solution peut être utilisée à plusieurs reprises; des pertes partielles de l'agent moussant, au cours du procédé, peuvent aisément être remplacées au cours de chaque cycle. Des agents tensioactifs cationiques peuvent être utilisés au lieu d'agents anioniques, le moussage et l'affaissement de la mousse étant régulés de façon à présenter des pH opposés. Des économies peuvent être réalisées en ce qui concerne l'eau, les produits de forage chimiques et les tours de décantation et autre servant à enlever des matières particulaires de la mousse.

Date Apr. 6, 1995A dispenser container for a paste is provided. The dispenser container is formed from a cylinder open at one end for holding the paste, a displaceable tightly fitted follower plate means is arranged at the open end of the cylinder and a dispenser for transporting the paste from the container is arranged to cooperate with the follower plate. A motor and transmission are mounted near the center of the follower plate and has a shaft which extends through the follower plate and has mounted thereon a multiple blade stirrer. The stirrer rotates in the paste below the follower plate. The dispenser removes the paste from the container at a position away from the center of the follower plate in an area below which the multiple blade stirrer rotates. The multiple blade stirrer by rotating in the paste lowers the viscosity and permits the paste to be more easily transported from the container by the dispenser.
