Abstract: In accordance with the principles of the present invention, a food steamer is provided. The food steamer includes an upper generally bowl-shaped portion defining a plurality of apertures and a lower portion comprising a stand. The upper generally bowl-shaped portion includes a lip that defines a plurality of scallops. A handle portion extends upwardly from at or near the center of the generally bowl-shaped upper portion. The upper generally bowl-shaped portion, the handle portion, and the lower portion formed of one piece molded silicon.

Abstract: The present invention provides methods for making manganese sulfide without the need for recycling a significant amount of manganese sulfide back to the reaction chamber. The methods are performed by admixing substantially pure manganese, substantially pure sulfur, and iron pyrite. The manganese and sulfur are then reacted to form manganese sulfide. Iron pyrite regulates the reaction and enables the use of conventional equipment in the methods of the present invention. After the reaction ends, the manganese sulfide product is separated from the unreacted manganese, sulfur, and iron.

Abstract: In a process for the production of 2-nitrobutylmorpholine from 1-nitropropane, morpholine and formaldehyde the improvement comprising mixing 1-nitropropane and morpholine, heating to about 55-60.degree. C., adding formaldehyde over about a 3-4 hour period, holding the reaction mixture at about 55-60.degree. C. for about a 2-3 hour period to make a total addition/holding period of at least six hours, cooling the reacton mixture to form a two phase oil/aqueous system and concentrating the oil layer to 2-nitrobutylmorpholine by removing excess water and 1-nitropropane.

Abstract: An improvement in the process for the production of P-1487 from the reaction of 1-nitropropane, 37% formaldehyde and morpholine, the improvement comprising mixing 1-nitropropane and 37% formaldehyde at a temperature of 40.degree.-42.degree. C., adding morpholine maintaining the temperature at 40.degree.-42.degree. C., holding the mixture for two hours at 40.degree.-42.degree. C., cooling to allow layer separation, separating the upper oil layer and concentrating the oil layer to P-1487 by removing excess water.
