Abstract: "PROCESSO PARA SUPRIMIR A FORMAçãO DE ESPUMA EM UM SISTEMA AQUOSO". A presente invenção refere-se a um processo para supressão de espuma de um sistema aquoso que envolve combinar água e pelo menos uma composição desespumante que possui peso molecular equivalente de hidroxila de 4000 Da, e um ponto de névoa menor ou igual a 30<198>C em solução aquosa a 1 %. Os desespumantes com alto peso molecular equivalente de hidroxila da presente invenção apresentam excelentes propriedades desespumantes em um ponto de névoa baixo. Adicionalmente, desespumantes da presente invenção apresentam propriedades desespumantes que são melhores do que desespumantes tendo o mesmo ponto de névoa que são baseados em copolímeros de polioxialquileno preparados na presença de hidróxido de potássio. As propriedades de desformação de espuma superiores dos desespumantes da presente invenção são particularmente úteis na fabricação ou processamento de produtos alimentícios.

Abstract: An interlocking collar (72) secures a bag neck (46) in a keg aperture (42) of an alcohol beverage keg container (22). The interlocking collar is mounted in press fit surrounding relation with a peripheral wall portion of the bag neck. The collar has an outer peripheral wall portion sized larger than that of a keg aperture. The collar (72) has a recessed groove (76) in the collar outer peripheral wall portion for receiving in press fitting and sealing relation a keg flange (40) that defines the keg aperture. The collar outer peripheral wall portion has a resilient edge portion (78) adjacent the recessed groove that deflects to permit the interlocking collar to pass through the keg aperture and receive the keg flange in the recessed groove. The interlocking collar has a plurality of locking passageways (80) placed around the interlocking collar and axially extending through the interlocking collar between the neck and recessed groove. A latch member (82) has a plurality of locking fingers (84) that extend axially through the locking passageways to prevent deflection of the resilient edge portion of the interlocking collar after the collar is placed in the keg aperture.

Abstract: A nozzle assembly for extruding a tube has an outer housing sleeve having an inner surface centered on an axis and having an axially forwardly directed front end and a core formed of attached-together front, intermediate, and rear core ports. The front core part lies within the sleeve at the front end thereof and forms with the inner housing surface an annular axially forwardly open extrusion passage. The intermediate core part lies within the sleeve axially behind the front core part and is formed with a pair of grooves opening radially outward into the passage and each defined by a respective annular rear face extending generally perpendicular to the axis, a respective annular front face confronting the rear face and extending generally perpendicular to the axis, and a heart-shaped annular surface axially bridging the respective faces, facing radially forward, and having a portion forming a radially forwardly directed point. The rear core part lies within the sleeve axially behind the intermediate core part and axially rearwardly closes the passage. At least one feed passage in the rear and intermediate core parts serves for feeding a mass to be extruded under pressure to the grooves at locations therein generally diametrally opposite the respective points. Each of the grooves has its region of greatest radial depth at the respective location and the feed passage opens radially into the grooves.

Abstract: A frame start word derived by superframe formation is found by testing for the presence of a correct binary value combination each bit position in a time window having the length of as many bits as framing bits are spaced apart, with the inclusion of so many overframes that a decision can be reached on the possibility of a relationsip to the frame start word. If this is to be excluded the corresponding bit position is flagged and thereafter no longer taken into consideration. Otherwise, the next binary value of the corresponding bit position is inferred from the binary value present. The procedure is continued, always including the same number of overframes until only one unflagged bit position remains.

Abstract: A safety apparatus includes a safety device and a centrifugal force speed governor for preventing overspeed conditions of an elevator car in both the downward direction and the upward direction. A bracket attached to the elevator car slidably retains a shaft at right angle to a guide rail attached to an elevator shaft wall. A U-shaped frame is attached to an end of the shaft and rotatably carries a running wheel. A compression spring extends over the shaft between the bracket and the frame to bias the running wheel against the web of the guide rail. On each side of the running wheel, a pair of release levers are rotatably supported to rotate during travel of the car in normal operation. In response to an overspeed condition, the release levers pivot into engagement with a pair of stationary ratchet wheels which are connected with a pair of actuating levers. The ratchet wheels are rotated by the running wheel which movement rotates the actuating levers. The actuating levers each move a release arm and one of the levers is connected to an actuating rod, which in turn is in connected to a release arm of another safety device on the car. The release arms extend into a wedge box of the safety device to actuate wedge-shaped jaws to engage the guide rail. For resetting the safety apparatus, the elevator car is restarted after a safety stop in the opposite direction of travel.

Abstract: A thermosetting powder coating composition according to the present invention comprises as binder a co-reactable particulate mixture of a carboxylic acid-functional polyester component and a curing agent having groups reactive with carboxylic acid groups, characterized in that the carboxylic acid-functional component comprises a semi-crystalline polyester having an acid value of from 10 to 70 mg KOH/g and a hydroxy value of no more than 11 mg KOH/g. Generally the semi-crystalline polyester has one or more Tg values less than 55 DEG C, a sharp melting point of 50 to 200  DEG C and preferably a number average molecular weight of at least 1600. The composition may, if desired, include an amorphous polyester and the curing agent may be, for example, an epoxy resin or a bis(beta-hydroxyalkylamide). Coating compositions of the invention cure faster than in the absence of semi-crystalline polyesters and the thermoset coatings prepared therefrom have improved appearance and mechanical properties (especially flexibility).

Abstract: Detecting and localising specific nucleic acid sequences in a sample involves the use of Probe Nucleic Acids, the production of nucleic acid binding regions and the use of nucleic acid Target Binding Assemblies to detect and localise specific Target Nucleic Acids. The detection and localisation of the Target Nucleic Acid is accomplished even in the presence of nucleic acids which have similar sequences. The method provides for a high degree of amplification of the signal produced by each specific binding event. In particular, methods and compositions are presented for the detection of HIV and HPV nucleic acid in samples. These methods and compositions find use in diagnosis of disease, genetic monitoring, forensics, and analysis of nucleic acid mixtures.

Abstract: A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus having an outer cylinder having an inner cylindrical surface coaxial with a smaller radius cylindrical mandrel. An endless base structure for the endless belt structure is disposed within the outer cylinder on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose, is then inserted into the outer cylinder forming a nip of converging geometry between the nose and the inner cylindrical surface. Polymeric resin material is dispensed continuously into the nip while the cylindrical mandrel is gradually moved completely into the outer cylinder. The nose forces the polymeric resin material into the endless base structure, and air bubbles out, while forcing the endless base structure against the inner cylindrical surface. After the polymeric resin material is cured, the endless belt structure, having a totally impregnated, air-bubble free endless base structure with a coating on its inner surface, may be obtained upon removal from the apparatus.
