Abstract: The present invention provides methods and systems of incorporating a mineral based particulate into Portland cement including agglomerating a particulate material and an agglomerating material to produce an additive, introducing the additive into a raw feed before burning the raw feed. By introducing the additive before burning, minerals are added to cement clinker.

Abstract: A delivery system a soldering paste to an electronics package includes a pressurized supply of via fill paste and a pressure head attached to the pressurized supply of via fill paste. The pressure head includes a main body and a wear portion. Attached to the wear portion is a gasket positioned along one surface of the pressure head. The pressure head also includes a flow dispersion regulator which includes a feed tube positioned within the main body, the feed tube has a plurality of flow regulating openings. The flow regulating openings in the feed tube are sized to maintain a substantially constant pressure at each of the flow regulating openings. Positioned between the main body and the wear portion is a flow equalization grid. The flow equalization grid includes a multiplicity of openings. Attached to the wear element is a gasket. The pressure source preferably includes a ram press.
