Title: Biological systems for manufacture of polyhydroxylalkanoate polymers containing 4-hydroxyacids
Inventor: SKRALY FRANK A
IPC: C12N9/02
Filed: 1998-09-18
Abstract: The gene encoding a 4-hydroxybutyryl-Co A transferase has been isolated from bacteria and integrated into the genome of bacteria also expressing a polyhydroxyalkanoate synthase, to yield an improved production process for 4HB-containing polyhydroxyalkanoates using transgenic organisms, including both bacteria and plants. The new pathways provide means for producing 4HB containing PHAs from cheap carbon sources such as sugars and fatty acids, in high yields, which are stable. Useful strains are obtained by screening strains having integrated into their genomes a gene encoding a 4HB-CoA transferase and/or PHA synthase, for polymer production. Processes for polymer production use recombinant systems that can utilize cheap substrates. Systems are provided which can utilize amino acid degradation pathways, .alpha.-ketoglutarate, or succinate as substrate.

Title: Media depositing system and method
Inventor: ZICKELL THOMAS J
IPC: B05C5/00
Filed: 1997-10-09
Abstract: A system (10) and method for depositing a pattern of media (2) on a moving surface (22) includes a media depositing apparatus (10) that deposits media (2) in a predefined pattern on the moving surface (22). A  media applicator roll (12) having a media receiving region (18), such as engraved or raised portions, receives the media (2) from a media feeder (16) as the media applicator roll (12) rotates.

Abstract: According to the invention multiple shared-memory processors (11) are introduced at the highest level or levels of a hierarchical distributed processing system (1), and the utilization of the processors is optimized based on concurrent event flows identified in the system. According to a first aspect, so-called non-commuting categories (NCCs) of events are mapped onto the multiple processors (11) for concurrent execution.  According to a second aspect of the invention, the processors (11) are operated as a multiprocessor pipeline, where each event arriving to the pipeline is processed in slices as a chain of internal events which are executed in different stages of the pipeline. A  general processing structure is obtained by what is called matrix processing, where non-commuting categories are executed by different sets of processors, and at least one processor set operates as a multiprocessor pipeline in which an external event is processed in slices in different processor stages of the pipeline.
