Abstract: A process for treating calcium phosphate fine particles which includes the step of compacting the particles under pressure to form a sheet.

Abstract: Improved magnesium phosphate fast-setting cements comprising an effective amount of fiber to increase the impact strength of the cement. These fibers include glass, metal, organic and mixtures thereof.

Abstract: The coefficient of friction between floors and shoes, particularly in food plants, can be increased by applying thereto, an anti-slip composition comprising sodium bicarbonate and an abrasive, preferably calcium carbonate. Food grade compositions can be provided.It has also been found that sodium bicarbonate alone or in combination with an abrasive can be used to absorb oil, grease and chemicals from surfaces. An abrasive can be added to improve the anti-slip characteristics of the absorbant.

Abstract: Elemental phosphorus contained in waste ponds can be appropriately passivated to render them substantially less pyrophoric by bringing the elemental phosphorus-containing wastes into contact with an oxygen-containing gas. Substantially pure oxygen can be used to appropriately sparge the elemental phosphorus-containing wastes submerged in the waste pond. If desired, phosphorus values can be recovered in the form of an aqueous phosphate solution.

Abstract: Fish fillets, particularly those from high fat fish, can be storage stabilized and yield stabilized by means of a composition containing an alkali metal tripolyphosphate hydrated with lemon juice solids, an alkali metal acid pyrophosphate and an alkali metal sorbate at sorbate levels significantly less than required by prior art and without citric acid.

Abstract: A particulate solid activator comprising a porous material containing absorbed ammonium phosphate can be prepared by a process which comprises: heating a slurry of the porous material and an ammonium phosphate solution; and then spray drying the slurry to obtain the particulate solid activator. The porous material can be diatomaceous earth. The resulting particulate solid activator can be dry blended with a magnesium-containing compound, e.g. MgO, and an optional aggregate to form a magnesium phosphate fast-setting cement mixture. This mixture reacts in the presence of an aqueous component at ambient temperature to form a monolithic solid.
