  • Patent number: 9909804
    Abstract: A method of cooling using an extended binary refrigerant system containing methane and a C3 hydrocarbon such as propylene and/or propane is disclosed. The extended binary refrigerant from a compressor final discharge is separated into a methane-rich vapor fraction and at least one C3 rich liquid fraction so as to provide various temperatures and levels of refrigeration in various heat exchange stages. The method and corresponding refrigeration system can be utilized in plants utilizing low pressure or high pressure demethanizers.

  • Patent number: 9326440
    Abstract: An apparatus for maintaining a tillage implement such as a plow at a consistent working depth utilizes a spring biased quadrilateral linkage to maintain the tillage implement in a position having to float forwardly and upwardly from the working depth thereby preventing unwanted flotation of the tillage implement from the working depth until the tillage implement encounters a substantially vertical load.

  • Patent number: 8230021
    Abstract: A method for adding a customizable reply function to an interface in an instant messaging (IM) client, including the steps of identifying a string of characters to be associated with the reply function, choosing an action of the IM client to be associated with the reply function, selecting presentation characteristics of a representation of the reply function in the interface of the IM client, and incorporating the reply function into the interface of the IM client, where a subsequent user selection of the incorporated representation of the reply function in the IM client interface instructs the IM client to output the string of characters associated with the reply function and to perform an action associated with the reply function.

  • Patent number: 7787598
    Abstract: A method (100) and system (30) to enable automatic generation and testing of voice applications includes generating (102) a test driver application (TDA) (32) and generating (104) a modified original voice application (34) to be tested by the TDA within a call flow builder (10). The modified application can include or generate (106) “test hooks” or more particularly DTMF tones and DTMF grammars that can be used to synchronize the modified original voice application with the TDA. The TDA can test (110) all possible paths of the modified original voice application. Note the TDA and the modified original voice application can be generated and/or tested (112) in a test environment within the call flow builder or a telephony environment. The TDA can be automatically generated (108) to exercise all possible flows where the DTMF tones define the current state and location of the modified application.

  • Patent number: 7525007
    Abstract: An ethane or other hydrocarbon feedstock is steam cracked to produce an ethylene stream which is processed in an ethylene plant recovery section to separate an ethane recycle and a polymer grade or chemical grade ethylene product stream. A portion of the ethylene product stream may then be reacted by dimerization to produce a butene stream. These formed butenes and/or butenes recovered from other sources and another portion of the ethylene product stream are reacted by metathesis to produce a propylene stream which is deethanized and separated from heavier hydrocarbons to produce the propylene product. The butene product stream may also be deethanized and is separated from heavier hydrocarbons. The overhead from the metathesis section deethanizer may be recycled to the ethylene plant recovery section. The reflux for the metathesis section deethanizer may be generated from the overhead or may be a portion of the ethylene product stream.

  • Publication number: 20070191572
    Abstract: Resol beads are disclosed, having a relatively narrow size distribution, prepared in high yield by reaction of a phenol with an aldehyde, with a base as catalyst, in the presence of previously-formed resol beads, a colloidal stabilizer, and optionally a surfactant. The resol beads may be thermally treated to prevent sticking and clumping and have a variety of uses, such as in the formation of activated carbon beads.
