Abstract: An anti-acid pharmaceutical composition for the rapid and prolonged neutralization of gastric acidity with mucosa-protecting activity in powder form to prepare, by dispersion in water, a pharmaceutical solution or suspension for oral use characterized in that the composition includes sodium alginate; an anti-acid soluble agent or a combination of anti-acids; an inhibitor of proton pump; diluent and sweetening agents, wherein a) at least 30% of sodium alginate present in the formulation along with the total of the inhibitor of proton pump are homogeneously distributed over the surface of the total soluble anti-acid agent of the combination of anti-acids of the composition; and b) the rest, about 70%, of sodium alginate present in the formulation contains a percentage of humidity of less than 2%.
Abstract: An apparatus and method for welding strap connections between inner grid straps of a spacer grid using a laser tool, and a spacer grid manufactured by the same, in which the strap connections between the inner grid straps of the spacer grid are seam-welded continuously or intermittently using the laser tool, so that the structural strength of the spacer grid is increased, a spattering phenomenon, in which a welded material is spattered during welding, is reduced, and thermal deformation is reduced. Further, fine welding is possible, and thus the welded bead of each strap connection between the inner grid straps can have a small size, and the number of welding defects can be reduced. In addition, the flow resistance of a coolant is reduced, and thereby the pressure drop of the coolant can be reduced As a result, the load on a flow pump for the coolant can be reduced, and economic efficiency and safety can be improved.
