  • Publication number: 20220211073
    Abstract: The present disclosure relates to processes for recovering valuable products from Fabaceae family plant fractions, in particular from Medicago sativa ssp. The processes disclosed herein include processes for obtaining macrofibers, microfibers, a saponin precursor, chloroplast liquid and dry compositions and a Rubisco precursor. There is also disclosed herein processes for extracting from Fabaceae family plants valuable compounds such as proteins, enzymes, peptides, amino acids, fatty acids, fatty alcohols, terpenes, phenols and pigments. The processes may comprise at least one of separating plant fibers while attenuating shear forces, maintaining the temperature at or below 45° C., maintaining the pH above 4 and adding antioxidant and/or antimicrobial agents. Compositions comprising these recovered Fabaceae family plant products and uses thereof are also disclosed.

  • Publication number: 20060117012
    Abstract: A critical parameter/requirements management process model for managing a development program for a product and an associated product structure-driven critical parameter/requirements management tool and environment is provided. In one embodiment, the process includes a product structure classification scheme, a parameter/requirements classification scheme, a parameter/requirements process and maturity model, and in-process and requirements conformance views. In one embodiment, the tool includes a user interface layer, a business layer, a data layer, and a database. The user interface layer may include a product structure feature group, an add/edit/link feature group, a manage maturity feature group, and a manage conformance feature group. The tool may be implemented as a web server accessible to user workstations operating as thin clients.

  • Patent number: 4914382
    Abstract: A high voltage measuring circuit for broadband measurement of transient signals occurring in high voltage apparatus. The measuring circuit is housed in a shielded housing having an input sensing circuit for connection to a capacitive grounded tap of the high voltage apparatus. The sensing circuit is connected to an output circuit through an electrical shielded connection. The measuring circuit generates output signals which are replicas of the transient signals appearing on the bushing of the high voltage apparatus. The broadband of the measuring circuit extends over a frequency range of from about 1 Hz to 1 MHz and has a signal level higher than background noise.
