Abstract: The digital input (3) is intended for a device for the detection of a digital signal when a particular event occurs in a process. Said digital input (3) can advantageously be used in a distribution network for electrical power, in the case of which the particular event initiates the operation of a switching device. The digital input has two first electrical connections (10, 11) to which direct current is applied from an external voltage source. Two second electrical connections (13, 14) are connected to a transmitter element (12), for example an auxiliary contact of the switching device, which emits the digital signal when the particular event occurs. A circuit which carries the digital signal to an optocoupler (22), which provides DC isolation, is also connected to the two second electrical connections (13, 14). The digital input (4) furthermore has a device (15) for converting the direct current, which is supplied from the exterior, into direct current which is DC-isolated from it. This device is operatively connected on the input side to the two first electrical connections (11, 12) and on the output side to the signal circuit. In contrast to digital inputs according to the prior art, only signal currents are supplied via the two second electrical connections (13, 14). In consequence, only very simple protective measures need be taken against the electrical and electromagnetic interference level on these electrical connections (13, 14). <IMAGE>

Abstract: A process is disclosed for the production of alkyl tertiary alkyl ethers in C₄+ hydrocarbon streams rich in isoolefins, typically containing catalyst deactivating amounts of dienes and/or compounds containing heteroatoms. The process is especially advantageous in extending the cycle length for the zeolite catalyzed etherification of isoolefins in C₄+ FCC gasoline by reducing catalyst aging. It has been discovered that if hydrogen is co-fed with the alkanol and C₄+ isoolefin rich feedstreams to an etherification reaction catalyzed by acidic zeolite wherein the zeolite has been impregnated with a noble metal the rate of catalyst aging or deactivation is stantially lowered. The process is especially effective, i.e., catalyst aging is particularly reduced, when hydrogen is co-fed to an etherification reaction using acidic zeolite Beta catalyst containing palladium.

Abstract: An image (MI) is defined, in correspondence with a predetermined polyhedral meshing of a portion of space, by a digital value for each vertex of the meshing. A polygon processing (30; 1450; 1650) receives a representation of a plane polygon (F) with p vertices, p respective values for these p vertices, and a threshold (S); it supplies, in correspondence with the polygon F, a list of oriented segments linking points of the edges of the polygon which are interpolated as equal to the threshold, with a predetermined direction convention. A polyhedron processing (20; 1445; 1645) receives a representation of a polyhedron (POLYED) with the values at its vertices and a threshold; then it invokes the polygon processing means (30) for all the faces of the polyhedron, which supplies a list of oriented segments; then it associates with a polyhedron a list of closed and oriented cycles, constituted by segments of the said list of segments. Main processing means (10; 1440; 1640) sequentially present a plurality of polyhedrons of the said meshing to the polyhedron processing means, with the values associated with their vertices and a threshold. The cycles thus obtained belong to an iso-surface of the image for the said threshold value. <IMAGE>

Abstract: System consisting of a non-absorbent mineral litter and of a device making it possible to increase its efficacity over time by sterilising processing and regular and automatic drying of the water from urine and faeces. The invention relates to a process making it possible to increase the longevity and the efficacy of mineral litters for small domestic pets by rapid and active drying of the grains making up this litter. It consists of a rectangular tray (1) having a central orifice (lower chimney) (2). In this tray, at mid-height, a slotted floor (3) is arranged, with a more or less loose frame supporting the bottom (4) containing the treated non-absorbent mineral litter (7). A low-power (20-40 watt) electric radiator (5), fed with 12 volts is placed under the slotted floor (3) and heats the air of this enclosure, creating a vertical convection, the hot air escaping via the upper chimneys (6).   The urine of the cat dissolves the adsorbed bactericidal products, and releases the perfumes contained during its vertical travel. On contact with the bottom (4), the urine diffuses laterally in a very rapid way, creating a patch of large diameter which is rapidly dried by the hot air flowing in this enclosure. On contact with this bottom, the urine also undergoes bactericidal treatment and releases a perfume into the air current of the lower enclosure. By the rapid drying of the litter as well as by the bactericidal and perfuming action, the device described allows preservation and enhancement of the performance of non-absorbent mineral litters for small domestic pets. <IMAGE>

Title: Improved mask for photolithography
Inventor: CHEN JANG FUNG
IPC: G03F1/36
Filed: 1993-01-15
Abstract: An improvement for reducing proximity effects comprised of additional lines, referred to as intensity leveling bars, into the mask pattern. The leveling bars perform the function of adjusting the edge intensity gradients of isolated edges in the mask pattern, to match the edge intensity gradients of densely packed edges. Leveling bars are placed parallel to isolated edges such that intensity gradient leveling occurs on all isolated edges of the mask pattern. In addition, the leveling bars are designed to have a width significantly less than the resolution of the exposure tool. Therefore, leveling bars that are present in the mask pattern produce resist patterns that completely developed away when a nominal exposure energy is utilized during exposure of photoresist.

Abstract: La présente invention concerne un procédé et un appareil conçu pour supprimer et/ou égaliser un signal fantôme. Un signal de test reçu est comparé avec une version idéale de ce signal de test. Les coefficients d'un filtre de correction appliqué au signal test reçu sont ajustés de manière à ce que le signal de sortie du filtre corresponde le plus possible au signal de test idéal. Mais la longueur du filtre est limitée et dans beaucoup de cas une annulation suffisante du signal fantôme n'est pas possible. Selon l'invention, un premier filtre adaptatif long LMS (LMS1) qui peut avoir plus de 1000 prises réduit au minimum l'erreur (epsilon) entre le signal de sortie filtré (y) du signal d'entrée déformé(x) (signal de référence transmis) et un signal de référence idéal. Un positionneur (14) prend les coefficients (C1) du premier filtre LMS et détermine le sous-ensemble de petits filtres le plus utile, séparés par des retards variables. L'information de position (PI) calculée dans le positionneur comprend les longueurs de ces retards. Le sous-ensemble de filtres,avec les retards variables, forme un second filtre adaptatif (LMS2) avec un nombre de prises correspondant à celui du premier filtre LMS. Les coefficients correspondant aux retards "bornes" peuvent être considérés comme réglés à zéro et les emplacements des éléments à retard du second filtre LMS demeurent fixes. Les coefficients des parties de filtre (correspondant aux petits filtres) sont modifiés de manière adaptative jusqu'à ce que la meilleure correspondance entre le signal de référence reçu filtré et le signal de référence idéal, soit atteinte. Le premier et le second filtres LMS n'ont pas besoin de travailler en temps réel. Après l'établissement de la modification des coefficients de filtre des sous-ensembles, ces coefficients (C2) sont copiés sur un filtre principal en temps réel (MF) travaillant sur le signal d'entrée entier, par exemple un signal TV, à l'exception dudit signal de référence. Le filtre principal comprend un sous-ensemble respectif de
