  • Patent number: 5597416
    Abstract: The present invention is a new crystalline sugar product and method of making same which includes forming a bi-dimensionally stabilized sugar crystalline frame from an outer portion of an amorphous shearform sugar mass, and, subsequently, converting the remaining portion of the mass to a substantially completely crystalline structure which retains the cross-sectional dimension of the sugar crystalline frame. The present invention also includes co-crystallizing an additive, especially a bio-affecting additive, during the process to provide a co-crystallized product. The structure of the crystallized product can also be loaded with a non-solvent liquid by force of capillary action in the space created within the structure during the conversion from amorphous mass to crystalline structure.

  • Patent number: 5545312
    Abstract: A method and apparatus for replacing particles in a process that transfers particles is disclosed. This invention employs a seal zone which is in communication with two zones of the process and in which particles that are being added to the process are purged. This invention allows particles to be replaced without reducing the normal rate of particle transfer through the process, which results in a savings in downtime costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

  • Patent number: 5538624
    Abstract: An improved catalytic process for heavy hydrocarbon conversion (usually but not necessarily in the presence of nickel and vanadium in the feedstock and on the catalyst) to produce lighter and selective molecular weight fractions. This process is specifically targeted as a means of retaining specialty high-valued, preferably microspherical additives (SHVA) which assist in attaining preferred conversion products such as gasoline, especially the recent gasolines meeting compositional requirements of "Reformulated Fuel".Selective magnetic retention of these high-cost specialty additives can be achieved by incorporating into them selective magnetic moieties, preferably manganese, the heavy rare earths and superparamagnetic iron. Selective retention is achieved by passing spent or regenerated catalyst containing small amounts of these SHVAs through a magnetic separator, and selectively recycling them back to the circulating catalyst.

  • Patent number: 5535469
    Abstract: An improved abrasive pellet for use in abrading fabrics during a wash cycle. A pellet is formed of a mixture of plastic resin, plasticizer resin and abrasive filler mixed at temperature sufficient to maintain the mixture as a liquid. The mixture is then extruded through a die of a desired shape and cut so that a pellet of desired cross-sectional shape and size is formed. The pellet is hard at room temperature, but becomes pliant at normal wash water temperatures. The abrasive filler provides the desired abrasive qualities in the pellet.

  • Patent number: 5523014
    Abstract: An originally viscous, non-flowable and non-pumpable cleaning composition made less viscous, and flowable and pumpable by the addition of at least one thickening agent to the composition. The cleaning composition includes an oil phase including at least one of a hydrocarbon oil and a hydrocarbon solvent and mixtures thereof, and at least one of a fatty acid and a non-fatty acid soap surfactant; and a water phase including water and a base. The addition of at least one thickening agent in various amounts relative to the amount of water in the composition makes the composition flowable. In particular, the addition of from about 2 to about 38 percent by weight of at least one thickening agent has been found to be suitable to provide a flowable composition containing between about 30 and 55 percent water. A method for the preparation of flowable cleaning compositions is also provided. The cleaning composition (13) forms a novel combination with a container (10) as a replacement element for dispensing apparatus.
