    摘要: Shock absorbing devices utilize rheopexic fluid contained in a deformable sealed chamber which is subjected to external shock forces. Upon application of the shock forces to the deformable sealed chamber, the rheopexic fluid filled therein is exerted with shear stress which causes the rheopexic fluid to increase its consistency and shock absorbent characteristics as a function of increasing shear stresses applied thereto. Additionally, when used in an application wherein the device is placed against a body part of a user, the rheopexic material "molds" itself to the body portion of the user. When left at rest, the rheopexic material returns to its initial fluid, low-consistency state.

    摘要: Compositions comprising calcium carbonate and processes for making such compositions are provided. The invention provides a granulation comprising about 95% to about 99% by weight calcium carbonate, about 0.5% to about 5% by weight of a binder and about 0.03% to about 3% by weight of a porosity increasing agent. A pharmaceutical or nutritional composition prepared from such a granulation comprises about 90% to about 99% by weight calcium carbonate, about 0.03% to about 3% by weight of a porosity increasing agent, and about 1% to about 10% by weight of other excipients. The composition provides a smaller tablet than conventional calcium carbonate compositions, for improved ease of swallowing.
