Abstract: An apparatus for separating undesired particles from a suspension flow of pulp and for dividing the suspension flow into fractions is described. The apparatus comprises a housing having a first chamber with an inlet for the suspension flow and a first outlet for the undesired particles, a second chamber with a second outlet and communicating with the first chamber through a first annular gap, and a third chamber with a third outlet and communicating with the second chamber through a second annular gap, the radial extension of the second gap being less than that of the first gap. First and second rotating discs are carried by a shaft for common rotation therewith. The first disc is disposed in the first chamber in front of the first gap to separate the undesired particles by means of teeth protruding from the first disc. The second disc is disposed in the second chamber in front of the second gap to remove, by means of teeth protruding from the second disc, particles in form of twigs, undissolved fiber bundles and any remaining undesired particles from the suspension flow in front of the second gap. The discs have cavities axially aligned with the first and second gaps, respectively, to form axial passages, said second disc and said second gap cooperating to divide the suspension flow into a coarse fraction which is removed through the second outlet and a finer fraction which passes through said second annular gap and is removed through the third outlet.

Title: Casting of gradient gels
Inventor: SOANE DAVID S
IPC: C08F20/52
Filed: 1990-05-01
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are presented for the casting of gradient gels, without voids,  in confined support structures such as thin slab-type configura-tions.  Furthermore, by using a differential activation scheme for the casting, the method makes it possible to produce such gels in slabs of capillary cross-sectional dimension.  According to a preferred method, a gradient slab gel  is cast by filling a countable number of grooves in a first plate with a first gelling liquid. A gel casting region for a slab gel is formed by spacing the first plate apart from a second plate so as to provide a flow path between the first and second plates which has a directional component orthogonal to the grooves.  A second gelling liquid is injected into the gel casting region between the plates, such that the first liquid mixes with the second liquid as the second liquid encounters each groove, thereby forming a gelling mixture  with  a  composition gradient.    The  gelling mixture is then caused to gel in the gel casting region, thereby forming a gradient slab gel.

Filed: 1991-04-29
Abstract: ABSTRACT OF DISCLOSURE      A vehicle hub  and bearing assembly which  includes  a sensor for use with an anti-lock braking system (ABS). The hub and bearing assembly in accordance with this invention includes a hub which rotates relative to a bearing pack assembly adapted to  be  mounted  to  a  steering  knuckle  or  other  suspension component.   A  sensor exciter  ring  is  fit onto the hub and rotates with the hub upon wheel rotation.

Abstract: A method of and an apparatus for the high-resolution sea bottom prospecting, in which an electroacoustic paraboloidal transducer (P1-P10) is placed into water, the electrodes of which are near the focus of the paraboloid and are connected both to a capacitor bank (C1-C10) the capacitance of which may be varied at will and to a supply circuit (G) for the generation of an electroacoustic discharge between said electrodes. As the capacitance varies the delay time between the primary pulse or underwater prospecting pulse and the cavitation pulse is recorded at any discharge, and at the same time dominant frequency of the prospecting signal spectrum is determined. Afterwards capacitance values are set so as to provide both cavitation pulses the contribution of which to the resulting pulse is minimum and a dominant frequency spectrum as broad as possible. The preset capacitance values are assigned to a capacitor array (C1-C10) connected each to an electroacoustic paraboloidal transducer (P1-P10) dipped in water, the electrodes of which are supplied so as to generate the underwater prospecting pulse.
