Title: Polymer emulsion products
Inventor: RANKA AJAY I
IPC: C08F265/02
Filed: 1986-12-11
Granted: 1991-12-24
Abstract: Abstract of the Disclosure Polymeric latices formed by free radical initiated polymer-ization of a polymerizable alpha, beta-ethylenically unsaturated monomer component which contains from 0.1 to less than 30 percent by weight of an epoxy group-containing alpha, beta-ethylenically unsatu-rated monomer in aqueous medium and in the presence of a salt of an acid group-containing polymer are disclosed.  The resultant polymeric latices have higher molecular weights than polymeric latices prepared without the epoxy group-containing alpha, beta-ethylenically unsatu-rated monomer.  The polymeric latices are useful as resinous binders in coating compositions where they provide for excellent adhesion and flexibility in the coating.

Title: Method of treating cemented carbide bodies regarding their compositions and structures
Inventor: EKEMAR CARL S G
IPC: C22F1/00
Filed: 1987-01-29
Granted: 1992-01-28
Abstract: ABSTRACT            The present invention relates to a unique and advantageous method making possible a superior technical and economical separation of cemented carbide bodies based upon their com-positions and structures.            The critical point of the method is, that after formation of a melt by melting of the binder metal including dis-solved elements from the hard constituents there are so strong driving forces dependent on the grain size vari-ables, proportions and compositions of the hard constituent phases, that melt is re-distributed between cemented car-bide bodies in communicating contact. The re-distribution is determined by differences of mean grain sizes, grain size distributions, relative proportions and compositions of the hard constituent phases of the bodies.
