Title: Pipe connector and method of applying same
IPC: E21B29/12
Filed: 1988-01-11
Granted: 1993-01-07
Abstract: Disclosed are an improved repair connector 12 for a subsea tubular member 10 and the method of making such repair. The improved repair connector includes an annular housing 18 and an annular guide 16, the annular housing having internal grooves 32 filled with pressure compensating material, a concave recess 36 having serrations therein, a rib 26 having a downwardly facing shoulder on the interior of said housing, and threads 24 on the upper interior of said housing for receiving a string. Means 22 are carried by the guide for sealing against the exterior of a string on which the connector is to be installed. Also, a band of brittle material 42 is positioned within a groove 40 in the exterior of the housing which generates a noise upon the deformation of the housing responsive to completion of the forming of the tubular member therein. The method of connecting the improved connector includes the steps of preparing the casing at a level below the defect, lowering the improved connector into engagement with the upper end of the prepared casing within the well bore, exerting deforming pressure within the upper end of the casing to deform the casing into sealing engagement within the internal grooves in the connector, and releasing and recovering the means generating the deforming pressure.

Title: Sewage treatment plant
IPC: C02F3/12
Filed: 1988-02-04
Granted: 1992-08-05
Abstract: A sewage treatment plant in which sewage is introduced into a tank (1) or other suitable container, to form a mixed biomass and sewage liquid for treatment within the tank (1), by means of both fixed and suspended biomass. The fixed biomass attaches itself to a plurality of free draining media surfaces (18, 20) that are alternately exposed and submerged by the raising and lowering of liquid levels within the tank. The raising and lowering of the liquid surfaces is achieved by displacing liquid with pressurised air from an inverted box (13) that also contains a plurality of media surfaces (14). The treated sewage overflows into a final zone (24) which contains random media surfaces. Surplus sludge collecting in the final zone (24) is fed back close to the inlet by gravity through a non-return valve (23).

Then introduction of hygroscopic material into the hollow molding is continued, interrupted at the next location of a corner, the walls are made to bulge, until four locations of the sidewall in the hollow molding have been provided with a bulge, and the hollow molding is completely filled. Also, a device is described suitable for performing the process. This device comprises a stamp (16) for indenting the hollow molding and an ultrasonic sensor which responds to the filling level of the hygroscopic material in the hollow molding.
