Abstract:
A design-time status schema model describes the progress of a data object through a computing process. The status schema model includes status variables, processing actions and constraints for performing actions. The status schema model also may describe permitted changes to a status variable in response to performing an action. At runtime, the status schema model is used to control processing performed by, or on, an instance of a data object corresponding to the status schema model.
Abstract:
A computer-implemented method for a collaborative process of exchanging messages through an asynchronous messaging network. The method is embodied by a computer program that causes a computer system to retrieve information on local states and local state transitions related to each participant system from a first storage location, including information specifying local states of the corresponding participant system and events triggering, and resulting from, the respective local state transition; process the information to generate, and store in a second storage location, information on collaboration states and collaboration state transitions; retrieve information stored in the second storage location; process the information retrieved from the second storage location to generate information on incompletely specified terminal collaboration states among said collaboration states; and generate a result data object containing information on every incompletely specified terminal collaboration state found.
Abstract:
A computer-implemented method or computer system develops a process specification for a collaborative process involving distributed computer-based participant systems exchanging messages through an asynchronous messaging network. In operation, a computer retrieves, from a first computer system, information on process states and process state transitions in relation to each participant system. Information on collaboration states and collaboration state transitions of the process are stored in a second computer system and used to generate information on dead-end collaboration states.
Abstract:
A method of isolating 1-[N2-((S)-ethoxycarbonyl)-3-phenylpropyl)-N6-trifluoroacetyl]-L-lysyl-L-proline (lisinopril (TFA) ethyl ester, LPE). The solvent or solvent mixture used for the extraction is also a main constituent of the solvent or solvent mixture from which the crystallization takes place. High yield as well as good purity of the end product are obtained, without distillation. 1-[N2-((S)-ethoxycarbonyl)-3-phenylpropyl)-N6-trifluoroacetyl]-L-lysyl-L-proline (lisinopril (TFA) ethyl ester, LPE) is described as a precursor for producing an ACE inhibitor.
Abstract:
A method of preparation for acetals utilizing saturated or unsaturated aldehydes, in particular, the preparation of dimethylacetals of acetaldehyde, acrolein and methacrolein. The production of the acetal takes place in a liquid phase in the presence of a solid acid catalyst, such as a strongly acidic ion exchange resin or zeolite. The conversion mixture is extracted by means of water and by means of water insoluble organic solvents. There is obtained not only the desired acetals, but in addition also the unconverted initial quantities of the starting materials by a simple method and with very good yields.
