Abstract: A dental articulator. The articulator holds a dental model of the upper teeth of a patient in selected orientations with respect to a dental model of the patient's lower teeth and permits the dental models to be readily removed from and reattached to the articulator in a desired selected orientation between the models.

Abstract: High solids latex suitable for no-gel foam applications is prepared by polymerizing an aliphatic conjugated diolefin, optionally with at least one copolymerizable monomer e.g. styrene, acrylonitrile or vinylidene chloride, in an aqueous emulsion containing less than 6 parts by weight per 100 parts monomers of a polymerization promoting synthetic emulsifier system e.g. sodium alkyl sulfate or ether sulfate and/or sodium sulfosuccinate and from about 0.001 to less than 0.2 parts by weight of a water dispersible agglomerating agent comprising the reaction product of a polyoxyalkylene glycol having a molecular weight of at least 5,000 with the polyepoxide obtained by reacting epichlorohydrin with a polyhydric phenol.The latex is stable and can be compound with fillers and then frothed in the absence of gelling agents to produce a uniform foam.
