  • Publication number: 20190260816
    Abstract: A system for delivering content at varying qualities from a server to multiple client across a network has a server side converter and a client side converter. The server side converter makes unicast requests to a server for representations of content and converts these to multiple representations to be delivered as multicast streams. The client &de converter receives a request for content from clients, determines a representation of content to obtain and subscribes to an appropriate multicast stream. The client side then converts the multicast stream back into segments available to a client by unicast request. In this way, data is delivered efficiently across a network from a server side to a client side whilst maintaining compatibility that client devices can issue traditional unicast requests.

  • Publication number: 20070128728
    Abstract: The invention relates to a novel phagemid display system for packaging phagemid DNA into phagemid particles which completely avoids the use of helper phage. The system of the invention incorporates the use of bacterial packaging cell lines which have been transformed with helper plasmids containing all required phage proteins but not the packaging signals. The absence of packaging signals in these helper plasmids prevents their DNA from being packaged in the bacterial cell, which provides a number of significant advantages over the use of both standard and modified helper phage. Packaged phagemids expressing a protein or peptide of interest, in fusion with a phage coat protein such as g3p, are generated simply by transfecting phagemid into the packaging cell line.

  • Patent number: 6884760
    Abstract: The invention relates to water based wellbore fluids used during a hydrocarbon recovery process, such as drilling, fracturing, gravel packing and wellbore workover. According to the present invention, said wellbore fluid comprises a fluid loss additive and a bridging material that are hydrophobic in nature, hydrophobically modified or oil wettable. The wellbore fluid generates an active filter cake that once formed, is impermeable to an aqueous phase, thus reducing fluid loss and ensuring reduced damage to the formation, yet simultaneously is permeable to the back flow of hydrocarbons during a hydrocarbon recovery process.
