Abstract: A B S T R A C T                    MAGNETIC SEPARATION PROCESS      In a process for separating relatively magnetic mineral particles Pm  having magnetic susceptibilities X , with Xm > O from relatively non-magnetic particles P , having magnetic susceptibilities Xn, with Xm > Xn, all said particles are suspended in a liquid stream, which is supplied to a separating container. Said container is provided with an inlet and an outlet and forms a passageway for said stream therebetween. Furthermore an arrangement of magnetizable matrix elements provided in said passageway is magnetized. Said supplying and magnetizing are conditioned in such a way, that depositions of particles are obtained predominantly upon the downstream side of said elements. From all said particles magnetic particles Pm are captured to an effective amount upon said downstream side, thereby resulting in a high grade deposition.

Title: Fines retention in papermaking with amine functional polymers
Inventor: SMIGO JOHN G
IPC: D21H11/14
Filed: 1993-01-18
Abstract: ABSTRACT   Polyvinylaminals, optionally as the formed copolymer with polyvinyl hemiaminals, and polyvinyl acetals are added to a papermaking pulp slurry to improve the retention of fines in the final paper product.  This polymer is provided by reacting a poly(vinylamine) which can be a homopolymer or a copolymer containing vinyl alcohol and vinyl amine units with a monoaldehyde.  The aldehyde, such as butyraldehyde, modifies the structure of the polymer and increases its hydrophobicity.  The use of these polymers in papermaking involving the recycle of waste papers provides notable advantages in fines retention because of the high level of fines which normally accompany such recycle paper waste.

Abstract: ABSTRACT OF THE DISCLOSURE :               Quadrature signal generation circuit A quadrature signal generation circuit  (QGM)  is proposed that allows to directly control the phase shift between an in-phase (IS) and quadrature-phase (QS) carrier signal derived from a master carrier signal (CS) having a desired carrier frequency.         The circuit (QGM) derives first and second signals which are roughly orthogonal through an untuned RC- and CR-filter  respectively  (IRC,  RCQ)  and  then  derives  the mentioned carrier signals (IS, QS) by cross-wise adding to these first and second amplified signals, the output signals of the above filters. The orthogonality of the above carrier signals may then be controlled via a phase adjust signal (PAS) which modifies the sign and the amplitude with which the  above  mentioned  output  signals  are  added  to  the amplified signals.
