Abstract: Industrial processes for the alternating conversion of glycerol to either an amino alcohol product or propylene glycol are disclosed. Glycerol is converted to hydroxyacetone which may then be directly reduced to obtain propylene glycol or optionally reacted with an amine compound to produce an adduct that may be reduced to obtain an amino alcohol product.

Abstract: Processes for converting glycerol to an amino alcohol product involving reacting glycerol with a metal catalyst to obtain hydroxyacetone, and reacting the hydroxyacetone with an amine compound to obtain an adduct that is then reduced using a reducing agent to obtain an amino alcohol product are described.

Abstract: Processes for the conversion of glycerol to a product mixture of an amino alcohol product and propylene glycol are disclosed. Glycerol is converted to hydroxyacetone and the hydroxyacetone is reduced with a reducing agent or reacted with an amine compound to give an adduct which is reduced using the reducing agent to obtain a product mixture of propylene glycol and an amino alcohol product.

Abstract: A method for the reduction of acrylamide in food products, food products having reduced levels of acrylamide, and an article of commerce. In one aspect, the method comprises adding to a food material a multivalent cation, in one embodiment a water-soluble, non-chelated multivalent cation. In yet another aspect, an article of commerce communicates to the consumer that a food product has reduced or low levels of acrylamide.

Abstract: A measuring system includes a first circuit that produces a first signal. A transmission line has a first end and a second end where the first end is interconnected with the first circuit so as to receive the first signal. A second circuit is remotely located from the first end of the transmission line and interconnected with the second end of the transmission line so as to detect the first signal. The second circuit in response to detecting the first signal produces a second signal that is received by the second end of the transmission line. The first circuit detects the second signal and in response determines the length of the transmission line. The first signal and the second signal preferably have different frequencies and the transmission line is preferably a fiber optic cable.

Abstract: A rotary air classifier for separating light material from a mixture of heavy and light material, or for separating large particles from small particles in a single material or a mixture of materials, such as in the sorting of municipal garbage, in which a tapered, e.g. frusto-conical, vessel is mounted about an axis, so that the lower surface of the vessel slopes downwardly towards the open lower end. Air is caused to spiral from the open lower end to the open upper end and takes with it the ligher fraction of material to be classified. The heavy articles slide or roll downwardly out of the open lower end.
