Abstract: A pipe coupling comprising a housing which can be clamped about pipe ends which are to be interconnected possesses radially inwardly flexed end flanges. The housing encloses an inwardly open sealing gasket having a substantially C-shaped axial cross-sectional configuration made from an elastomeric material such as synthetic rubber. Both ends of this sealing gasket are supported upon the inner or confronting jacket surface of a respective truncated cone-shaped clamping ring. These clamping rings are supported in the housing at the region of their outer edge or outer region by means of the end flanges. The inner edge or inner region of these clamping rings is structured to mechanically engage or dig into the surface of the pipe ends during clamping of the housing. The inner edge or inner region of the clamping rings possesses a concave profile in order to reduce, on the one hand, the necessary force required during clamping of the housing for digging the inner edge or inner region into the pipe ends and, on the other hand, to clearly limit the depth to which the inner edge or inner region penetrates into the pipe ends.

Abstract: This invention relates to a method of reducing the particle size of solid particles and is applicable to the production of very fine particles of a wide variety of solids, includuing relatively hard solids. The method comprises milling a liquid suspension of solid particles in an agitated media mill (13), pumping the milled suspension through a particle size classification device (16) to separate the slurry into a coarse fraction (17) and a fine fraction (18), the particles of the coarse fraction having a greater median particle size than the particles of the fine fraction, recycling the coarse fraction (17) from the particle size classification device to the input of the mill (13), and recycling the fine fraction (18) by pumping (15) it to the classification device, wherein recycling of both coarse and fine fractions are continued until solid particles of the desired reduced particle size are produced. Preferably a single classification device and a single mill can be used, and particles having a median particle size of 0.3 microns or less and a relatively narrow particle size distribution can be produced, even using a hydrocyclone as the classification device.
