    摘要： Relatively pure monopotassium phosphate is produced from wet process phosphoric acid in a process wherein the phosphoric acid is mixed with potassium chloride and recycled components from downstream product and by-product recovery steps and heated to permit hydrogen and chloride to evolve from the melt as gases and wherein the melt is subsequently treated so as to remove impurities so that the monopotassium phosphate may be recovered as a relatively pure crystalline product with low chloride content.

    摘要： An apparatus for producing phosphoric acid by the recovery of P.sub.2 O.sub.5 from a phosphate ore is disclosed. A slurry of a phosphate ore in an aqueous phosphoric acid solution is formed in each of a plurality of reaction zones connected in series. Phosphate ore is introduced into the first reaction zone and phosphoric acid into the last reaction zone whereby the reaction of the phosphoric acid with the ore forms a slurry of coarse solids, fine solids and monocalcium phosphate in the phosphoric acid solution. A first process stream comprising coarse solids is removed from the first reaction zone and each of the other reaction zones and is tranferred to the adjacent, successive reaction zone. A second process stream comprising fine solids is removed from the last reaction zone and the other reaction zones and is transferred into the adjacent, preceding zone in a direction which is countercurrent to the direction of flow of the first process stream and is concurrent with the direction of flow of the phosphoric acid from the last to the first reaction zones. A differential of phosphoric acid concentration is maintained between the reaction zones with the concentration decreasing in each reaction zone in the direction of flow of the first process stream.

    摘要： A pneumatic tocodynamometer (“pTOCO”) (10) having a guard-ring (13) with a thin elastic membrane (18) stretched across a shallow spherical depression (12) trapping a small volume of air in the center of the guard-ring (13). A pressure transducer (17) may be molded into the body 11 of the pTOCO (10). In an alternative embodiment, the air volume beneath the membrane (18) of the pTOCO (10) may be connected via a low volume air conduit (14, 15) to a separate pressure transducer (16).

    摘要： Systems and methods for providing an alternative delivery point code may comprise receiving delivery data corresponding to a delivery point. Furthermore, the systems and methods may include determining if the delivery data includes a secondary element. Moreover, the systems and methods may include creating the alternative delivery point code based upon the secondary element if the delivery data includes the secondary element. The secondary element may comprise a descriptor or a secondary number associated with the delivery point. If the delivery data does not include the secondary element, a normal delivery point code may be created.

    摘要： Systems and methods consistent with the present invention encode a list so users of the list may make inquires to the coded list without the entire content of the list being revealed to the users. Each item in the list turns on one or more bits in the array 110. Once each item in the list has been encoded by an encoder, a bit array with high and low values is used to represent the items in the list. The bit array may be embodied in a validation system for allowing users to query the list to determine whether an inquiry item is on the list 105. The validation system determines which bits to check by executing the same coding process executed by the encoder. If all the bits are high, then the inquiry item is determined to be part of the list, if at least one of the bits is low, then the inquiry item is determined not to be part of the original list. An exemplary encoder and validation system comprises a standardizer, a hashing function unit, an extraction circuit, and an offset circuit.

    摘要： A method and system for sequencing deliverables using combined delivery codes and partial delivery point bar codes (DPBCs) provides pre-sequencing of deliverables for delivery carriers that has improved ordering with respect to the actual delivery route and accounts for un-coded new delivery points in the ordering process. A partial DPBC field is combined with a delivery code to generate the ordering sequence. The DPBC field is combined by generating delivery sequencing tables having sequence numbers splitting ZIP+4 codes into multiple entries delineated by ranges of the last two digits of the DPBC, that can then be flagged for ascending or descending delivery and assigned unique sequence numbers. The full address of actual delivery points is thereby concealed by the table, while providing more accurate sequencing conforming to actual deliver routes. New delivery points within a ZIP+4 code can be assigned a sequence number by reference to the last two digits of the actual address, providing further utility to the method.
