Title: Rollingly transportable press die apparatus
Inventor: KEIZER HAROLD F
IPC: B30B15/02
Filed: 1991-07-18
Abstract: A die structure for use in conjunction with a metal working press is provided without the usual large bottom plate member secured to the undersides of the spaced apart parallel members  projecting downwardly  from the underside of the shoe portion of the die.   To permit the plateless die structure to be rollingly  transported  from place  to place along a horizontal support surface, a plurality of specially designed lifter devices are secured to the die parallels and rotatably carry a plurality of roller members.  The lifter devices are pneumatically operable and,  when actuated,  drive the roller members downwardly beyond the common plane in which the bottom sides of the parallels lie to thereby elevate the die structure above a horizontal support surface and rollingly support the die structure thereon.   Upon deactivation thereof, the lifter devices permit the undersides of the die parallels to settle back down onto the support surface, thereby  stationarily  positioning  the  plateless  die  structure thereon.

Filed: 1991-08-07
Abstract: Disclosed is a method of removing sulfate ion from an aqueous sodium chlorate liquor. A crystallization temperature is selected between about -15 and about 0°C and the maximum concentration of sodium chlorate that is soluble in the liquor at that temperature is determined. The liquor is diluted so that the concentration of sodium chlorate in the liquor is less than that maximum concentration and the liquor is cooled to that temperature so that the sulfate ion in the liquor crystallizes as sodium sulfate decahydrate but the sodium chlorate does not crystallize.

Title: Esterified polyoxyalkylene block copolymers as reduced calorie fat substitutes
Inventor: COOPER CHARLES F
IPC: A23L5/10
Filed: 1991-10-10
Abstract: ABSTRACT OF THE DISCLOSURE   Esterified polyoxyalkylene block copolymers are useful as reduced calorie fat substitutes in food compositions due to their resistance to enzymatic hydrolysis and absorption upon ingestion.          The fat mimetics contain hydrophilic polyoxyalkylene inner blocks which tend to promote thickening or gelling of the composition when mixed with a minor amount of water, thereby lessening problems with anal leakage and short bowel transit times.

Abstract: 2102128 9220441 PCTABS00017 Encapsulated particles comprise a core surrounded by a coacervate coating that comprises a low critical solution temperature polymer and a water removal depressant for the temperature of reversible insolubilisation of that polymer. The composition is either in the form of dry particles or is an aqueous dispersion at a temperature below the temperature of reversible insolubilisation of the polymer in the absence of the depressant but above the temperature of insolubilisation in the presence of the depressant. The coating dissolves when the composition is mixed with water. The composition is made by forming a dispersion of the core particles in a solution of the polymer, heating the solution to cause it to precipitate as a coacervate, and then adding the depressant. The composition can be an aqueous dispersion or dry particles.
