Abstract: The present invention generally relates to a turbine coating apparatus and a spray gun assembly therefor. More specifically, the present invention relates to a spray gun assembly comprising a gun support mountable to the turbine coating apparatus and at least one spray gun mounted to the gun support. The spray gun is adapted for providing a spray of a coating substance onto a cluster of solid forms to be coated in the apparatus, where the spray defines a spray angle of less than 90 degrees relative to the coating plane defined by the cluster of solid forms in movement.

Abstract: Disclosed is a pharmaceutical controlled release tablet containing an active ingredient in combination with a carrier made of cross-linked amylose in which hydroxymethylpropylcellulose (HPMC) with a viscosity higher than or equal to 4000 cps is added as an adjuvant. The addition of HPMC to the tablet permits to control the effect of enzymes, and more particular alpha-amylase present in the intestinal medium, on the cross-linked amylose used as a carrier, and thus to reduce the dependence of the kinetics of release upon the concentration of enzymes present in the medium.
