Patent EP-0422681-A1 (EP)
Inventor: FU CHERNG-CHYI ROGER
IPC: A61K47/42
Filed: 1990-10-12
Abstract: An ophthalmologically acceptable collagen containing aqueous composition is disclosed. The composition contains collagen and is a flowable liquid at temperatures below mammalian eye temperature (32°C to 42°C) and forms a gelled sustained release matrix after administration to the mammalian eye. The composition is comprised of ophthalmologically acceptable collagen material, a pharmaceutically active non-steroidal antiinflammatory drug, optionally an antibiotic, a buffer, a nonionic ethoxylated alkylphenol surfactant, a quaternary ammonium preservative, a tonicifier, a chelating agent, and optional excipients in an aqueous carrier. The collagen in the composition undergoes a change from a flowable liquid to a gelled matrix after the formulation is administered to the eye. The gelled matrix of the formulation traps and physically holds the drug in the matrix. When applied, the gel will remain in place in the cul-de-sac of the eye substantially longer than liquid formulations and will allow for a sustained release method of delivery of the drug to the eye. The drug release from the matrix and the drug half life are such that the formulation allows for once a day or even less frequent dosing which increases the convenience and improves patient compliance.

Abstract: A solution to the problem in differential buses that the bus state for a given line pair is undefined when no unit is driving either of the bus lines in the pair. The lines in the bus pair are terminated to different voltage levels, thereby establishing a desired default condition when no unit is driving either line. The voltage offset between the two bus lines must be sufficient that differential receivers coupled to the bus when the bus is not driven can respond to the offset. At the same time, the offset must not be so great that a driver attempting to drive the bus pair cannot overcome the offset with enough margin for the receivers.

Abstract: Device for winding a web between winding rollers which act on the roll circumference and which initially form an essentially closed winding space and are arranged on a fixed rolling head, on the one hand, and a movable rolling head, on the other hand, the movable rolling head being moved during the increase in the roll diameter. A better accessibility of the roll, a higher winding speed and a larger roll, even where sensitive material is concerned, can be achieved if the movable rolling head is pivoted during this movement into a position having the function of a supporting roller. Furthermore, the control can be managed in such a way that the roll inside diameter is set different from the initial width of the winding space and a predetermined outside diameter for a given web length is thereby obtained. <IMAGE>

The amplifier circuit of the first branch is from an amplifier circuit having an H(s) transfer function of zero order, and an amplifier circuit having a LOW-PASS H(s) transfer function of one-order, in order to set the range of operating frequencies of the activated filter. The low frequency gain of the H(s) transfer function of the first branch amplifier circuit is regulated by control means applied to this circuit in order to adjust the characteristics of the activated filter, in said range of operating frequencies, between the band-stop and all-pass filter characteristics; the transfer function of the activated filter is of order two. Applications: in frequency doublers; and 0-90 DEG phase-shifters.

Abstract: @ A method for properly migrating seismic data which has been elevation-static corrected. The method is comprised of assigning a zero (or very small) migration velocity for data located below a datum, yet above the original recording surface elevation. A best estimated earth velocity is input into the migration algorithm to represent the earth below the original recording surface. For seismic data collected in water-covered environments where the water bottom is irregular, the method contemplates that the data lying above the water bottom are migrated using the migration velocity of water. The data lying at or below the water bottom are migrated with a migration velocity of zero. In a second step, are elevation-static corrected and migration is performed where the velocity is zero between the datum and the original surface. Data below the surface is migrated using the estimated earth velocity.

Abstract: Municipal sanitary sewage sludge is disposed of by an improved partial oxidation process without polluting the environment. Aqueous slurries of sewage sludge are upgraded by being sheared without heating, concentrated if necessary, and then mixed with a supplemental fuel, preferably coal. In one embodiment, the aqueous slurry of sewage sludge and the supplemental coal and/or petroleum coke are introduced into a shearing mixer for simultaneous shearing and mixing together. A pumpable aqueous slurry of sewage sludge-coal and/or petroleum coke is thereby produced having an increased amount of total solids and an increased heat content (HHV) as well as containing an increased amount of sewage sludge for reacting with free-oxygen containing gas in a free-flow partial oxidation gas generator. Hot quench water or steam produced by cooling the hot raw effluent stream of synthesis gas, reducing gas or fuel gas from the gasifier may provide heat for indirect heat exchange with other streams in the process.

Cette voie d'avance présente une première zone de mouvement, dans laquelle la partie de corps avance dans une position non fléchie, et une seconde zone de mouvement dans laquelle la partie de corps avance dans une position fléchie. Des organes magnétiques permanents pouvant fonctionner comme la partie de corps pendant le mouvement alternatif de la tige de lisse amènent la partie de corps à se déplacer de la position non fléchie à la position fléchie. Des organes de blocage fixes sont disposés sur un des côtés de la première zone de la voie d'avance et sont destinés à se placer en prise avec le prolongement de blocage situé sur la partie de corps, uniquement lorsque celle-ci se trouve dans la position fléchie.
