Abstract: An apparatus is disclosed for facilitating heat dissipation in an electrical device hat includes a core structure traversing a substrate when the core structure is in an installed orientation. The apparatus comprises: (a) at least one aperture through the substrate for accommodating traversing by the core structure; each respective aperture has periphery defined by a respective circumjacent face extending a height substantially equal with the substrate thickness; (b) a layer of thermally conductive material situated discontinuously on the circumjacent face of at least one respective aperture. The respective aperture is configured to establish a thermally conductive engagement with at least one facing portion of the core structure traversing the respective aperture in the installed orientation.

Abstract: Process for making rigid polyurethane or urethane-modified polyisocyanurate foams comprising the step of reacting an organic polyisocyanate composition with an isocyanate-reactive composition comprising a polyester polyol in the presence of an amine catalyst characterised in that the pKa of the conjugated ammonium salt of said amine is less than 12.

Abstract: A tablet rotary compression press for the manufacture of multi-layered tablets, comprising a rotationally driven rotor which has a die-plate with die-plate bores and top and bottom rams aligned towards the die-plate bores which are guided in ram guides of the rotor and are axially actuated by stationary control cams, an insertion device for a portion of the tablet-forming compacts which has two or more arms guided in a radially movable manner at the each end of which a compact is held and can be aligned towards a die-plate bore, wherein said rotor has circumferentially included thereon a support ring or support surfaces on which the compacts can be deposited in the positions approximately aligned towards the die-plate bores, the radial arms are disposed in the rotor, rotate therewith, and have radially movable gripping portions adapted to be radially moved to each other, and the rotor has provided therein a stationary guide with first and second guide cams the cam followers of which are interacted with by the

Abstract: A die for a rotary compression press, comprising a die holder axially supported in a guide bore and a die insert which is seated in the end-side bore of the die holder via a trunnion-shaped projection and is adapted to be mounted via releasable fastening means, wherein the projection is helically guided in the bore between axially spaced stops and is biased by a spring towards the associated front-end face of the die holder.
