  • Patent number: 11746101
    Abstract: Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.

  • Patent number: 10116582
    Abstract: In response to receiving a request from a user to initiate a new resource pool, a determination of a purpose of the new resource pool is made. The system identifies suggested resource allocations for the new resource pool, as well as suggested modifications for current resource pools of a user, and presents both to the user. The suggested resource allocations are determined based on the purpose of the new resource pool and user data associated with the user or other users. The user selects suggested resource allocations for the new resource pool and current resource pools. The processing systems initiate the selected resource allocation and/or the suggested modifications selected by the user at the time of initiating the new resource pool, and thus reduces the processing requirements for processing resource allocations since the allocations occur at the initiation of the new resource pool.

  • Patent number: 6682571
    Abstract: A process for making a pattern according to intended design on cloth or clothing, particularly denim clothing, dyed with a colorant or a dye through decolorizing is provided. Fabric or clothing dyed with a colorant or a dye is impregnated with a substance forming an oxidized active species upon electrolysis and inserted between a pair of electrodes, and electricity is applied to the electrodes, whereby only a part where electricity is applied is selectively decolorized to make a pattern with gradated effect.

  • Patent number: 6663677
    Abstract: Improved methods for wool whitening and garment washing are provided. More particularly, methods of the present invention employ a first reducing agent, preferably a borohydride material, and a second reducing agent, preferably a bisulfite material, to increase the brightness (whiteness) of wool and to reduce color components in certain garments, particularly denim. Methods of the present invention are particularly useful in the garment and piece goods industries.

  • Patent number: 6665678
    Abstract: Provided is a method, system, and program for performing a cursor operation. A result table is generated including rows corresponding to a subset of rows in a base table having data in one or more columns that satisfy a query predicate clause. A command is received to perform a cursor operation with respect to a subject row in the result table. A lock is obtained on a row in the base table corresponding to the subject row in the result table. An operation specified in the received command is performed with respect to the subject row after obtaining the lock. The lock on the row in the base table is released after performing the operation.

  • Publication number: 20030056296
    Abstract: A recycling process for liquid treatment of denim scrap comprising placing denim scrap on a support surface to form a thickness of flat, layered denim scrap. To the top surface is applied a compression plate to form the thickness of denim scrap into a compact cake. Then treatment liquid is passed through the interior of the compact cake in a direction parallel to the surfaces of the scrap, the liquid passing between opposed surfaces of the denim pieces. The denim scrap is preferably cut into relatively uniform sizes having their largest dimension less than about 4 inches.

  • Patent number: 6494923
    Abstract: In the method of temporarily coloring and later decoloring hair a hair colorant is applied and allowed to remain on the hair for an exposure time of 10 to 45 minutes at 20 to 50° C. and then rinsed out. Then at a later time, as desired, the hair is decolorized. The aqueous hair colorant contains 0.01 to 5 percent by weight of at least one dye compound of formula (IV), or a physiologically tolerated salt thereof; wherein n=0, 1 or 2 and R1 represents a C1- to C4-alkyl group, a hydroxyethyl group, a dihydroxypropyl group, a methoxyethyl group, a carboxyethyl group, a C1- to C4-sulfoalkyl group, an unsubstituted or substituted phenyl radical with halogen, sulfonic or carboxylic acid substituents; R2 represents a hydrogen, a methyl group, a carboxylic acid group, a carboxylic acid group esterified with a C1- to C4-alcohol or a carboxamido group; and Y represents an aromatic five-membered heterocyclic ring, which may or may not be benzoanellated.
