Abstract: Abstract A rotatable filter assembly comprises a rotor, in bearings in a container for fibre suspension. The centre of the rotor is formed by axial discharge tubes, into which hollow filter elements, forming annular filter discs open. A collecting hopper is provided extending into the centre of the filter assembly. The filter elements are provided to keep separately, at least dur-ing part of the rotation turn, a lower pressure inside than outside. Accor-ding to the invention the filter assembly is characterized in that each of the axial discharge tubes (6) is permanently connected to its own accumula-tor chamber (9) for filtrate, which is provided to keep during a first part (16) of the rotation turn of said drum (4) such a pressure, preferably atmospheric pressure that filtrate is brought to accumulate in the accumula-tor chamber (9), and that during a second part of the rotation turn of said drum (4) said accumulator chamber is provided to communicate with a device for filtrate discharge (11, 26) which is dimensioned to discharge the filt-rate from tube and accumulator chamber during this second part of the rota-tion turn.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method of forming a skelp into a rounded tubular form in the preparation of an electric resistance welded steel pipe.  Different from conventional methods, the skelp is bent in the initial and intermediate forming stages with-in a limited region alone along the centerline thereof to have a U-shaped forming flower.  Thereafter, the edge por-tions of the bent skelp are bent in the upstream fin pass rolls to have a curvature of at least 80% of the final curvature with simultaneous over bending in the boundary regions on both sides of the side portions of the rounded skelp.  Finally, the rounded skelp is pressed down in the direction to decrease the vertical diameter to bulge out in the transverse direction with simultaneous unbending the over-bent portions into the final curvature.

Abstract: Abstract of the Disclosure Bearing Race Retention Device and Method A bearing race retention device for a ball or roller bearing assembly mounted between a pair of relatively rotatable members is disclosed.  An annular race defines a smooth notchless cylindrical surface and a preselected diametral slip fit clearance with the first member for ease of assembly, and an annular groove of uniform and generally rectangular cross section is formed in the first member and is defined generally by a cylindrical seat and first and second side walls.  Advantageously, a swellable elastomeric ring of unrestrained uniform circular cross section is compressibly disposed in the groove during initial installation of the race to a mean groove fill condition of at least 65% in volume, is constrained by the side walls spaced apart about 1 1/3 times the diameter of the elastomeric ring and is of a thermoset material sufficient for volumetrically swelling upon exposure thereof to a petroleum-based lubricating fluid in the clearance so that it substantially fills the groove and frictionally holds the race from rotating.
