  • Patent number: 6183179
    Abstract: The present invention relates to a process for riveting materials by means of a blind rivet and corresponding blind rivets. The process of the invention in particular carries out the step of stretching the body of the sleeve (31) before blocking it from one part to another of an assemblage (13, 14) between an abutment head (50) and a blocking head (51). The extending of the body of the sleeve is especially permitted by the cooperation of a stop means (44) with a shoulder (36a) of the shank of the mandrel (32), and by the pulling exerted on the mandrel. The present invention also relates to blind rivets adapted to be set by the process of the invention.

  • Patent number: 6165371
    Abstract: Apparatus and method for accommodating and handling excess deliveries of combined sewage overflows to a sewage treatment plant supported and contained within an offshore moored vessel or platform, by diverting the excess deliveries to ballast tanks for temporary displacement of clean ballast water and to be returned to the treatment system when excess deliveries of combined sewage overflow are relieved. Fluids contained within the ballast tanks are utilized to provide buoyant support for process tankage. Baffles within the ballast tanks minimize undesirable mixing of the combined sewage overflows with the resident clean ballast water.

  • Patent number: 6073481
    Abstract: A method and device for sampling the pressure of inert purge gas flowing in two pipes to be welded at a joint comprising a sleeve for encircling the pipes during their coaxial alignment in end to end abutment, and an associated element with the sleeve forming a sealed chamber surrounding the joint and receiving gas that leaks out from the joint at the same pressure as the gas in the pipes, and a connection for connecting the chamber for measuring the pressure of the gas therein as an indication of the pressure of the gas flowing in the pipes; the method includes clamping the device around the pipes or sliding the pipes into the device.

  • Patent number: 5902484
    Abstract: Biological processes for treating wastewater include the conventional activated sludge process, which has continuous flow in and out of each treatment cell, and the sequencing batch reactor (SBR) process, which operates on a batch fill and draw basis. The first process operates at a constant level and requires the use of dedicated, relatively expensive external clarifiers to settle mixed liquor suspended solids and recycle activated sludge. The second process does not use separate clarifiers because treatment and settling of mixed liquor suspended solids is accomplished in a single basin, but has a variable level operation and resulting inefficient use of the treatment volume. This substantially constant level biological wastewater treatment process and system enables efficient treatment of wastewater, combining the advantages and eliminating the disadvantages of both SBR and activated sludge processes.
