Patent EP-0012501-B1 (EP)
IPC: C12N1/18
Filed: 1979-10-18
Granted: 1982-06-30
Abstract: Acid whey, the by-product from the manufacture of fresh cheeses such as cottage cheese, is clarified, filtered and subjected to lactose hydrolysis, splitting the lactose disaccharide into the monosaccharides glucose and galactose. The liquid is sterilized and cultured with Saccharomyces yeast e.g. Baker's yeast and used as a growth medium for that yeast. After yeast growth is substantially completed the yeast solids are separated and the liquid remaining is discharged into waste-water receiving systems, the liquid significantly reduced in organic waste loading as compared to untreated acid wheys.

Abstract: The method removes a contaminant, such as adhesive or ink particles, from wastepaper pulp. The method includes the steps of dispersing a monomer in the pulp so as to form droplets or beads which take up the particles e.g. by a process in which the particles are coated, absorbed or dissolved by, or adhere to the droplets or beads of monomer. The monomer is then polymerized to increase the rigidity of the droplets or beads, and the droplets or beads are separated from the pulp, e.g. by screening. The monomer or a mixtures of monomers are dispersed in the pulp by strong mechanical agitation and the agitation can be controlled to provide droplets or beads of monomer within a certain size range. Suitable monomers includes styrene, vinyl acetate, methyl methacrylate or mixtures of the same. The viscosity of the monomer phase may be increased by dissolving a homopolymer in the monomer to reduce the effect of shear forces caused by agitation. Benzoyl peroxide may be added to initiate polymerization.

Abstract: A method and apparatus for classifying desirable particles of powder metal by size and removing particles of undesirable material of a different density than the metal particles. There is included a housing 14 defining a closed flow path for a recirculated stream of protective gas otherthan ambient air. A supply device 34 introduces particles into the housing at a controlled rate in a downwardly falling stream. A plurality of receptacle trays 40 are disposed in the housing generally vertically below the supply device, each having a forward lip . 52 positioned forwardly in the direction of the gas flow of the trays thereabove. An electrostatic gas ioniser 42 is disposed upstream of the supply device and a screen 44 is disposed in the stream of gas between the ioniser and the supply device for attracting the ionised gas from the ioniser while allowing the passage of the gas therethrough for establishing the recirculated stream of.gasto impinge the stream offalling particles to impart to each particle a horizontal component of velocity so that the trajectories of the particles will vary depending upon size and density thereof for falling into the various receptacle trays. Because of the charge placed thereon, clusters of particles are broken up, i.e. the particles in such a cluster repel one another and separate.
