The present invention provides apparatus and methods for injection molding polymeric cannulae from liquid polymeric materials. The method includes injecting pressurized liquid polymer into a mold cavity and into an overflow and forming a conduit by forcing pressurized working fluid through the solidifying liquid polymer into the overflow. The invention provides a mold for fluid-assisted injection molding articles from polymeric materials, the mold comprising at least two parts defining a cavity having a conduit portion incorporating a needle portion; a channel for liquid polymer ingress; a channel for pressurized fluid ingress; and an overflow in communication with the conduit portion. The mold may incorporate a plurality of cavities. Preferably the volume of the overflow is equal to or greater than the volume of the conduit portion. Preferably the mold incorporates a separating means for separating the overflow from a cannula portion of an article formed in the mold.

Method and apparatus for generating a low tar, renewable fuel gas from biomass and using it in other energy conversion devices, many of which were designed for use with gaseous and liquid fossil fuels. An automated, downdraft gasifier incorporates extensive air injection into the char bed to maintain the conditions that promote the destruction of residual tars. The resulting fuel gas and entrained char and ash are cooled in a special heat exchanger, and then continuously cleaned in a filter prior to usage in standalone as well as networked power systems.
摘要:
A telecommunications assembly including a housing and a plurality of modules mounted within the housing. The modules includes a rear face in which is mounted at least one fiber optic connector. Within an interior of the housing are positioned at least one fiber optic adapters. Inserting the module through a front opening of the housing at a mounting location positions the connector of the module for insertion into and mating with the adapter of the housing. The adapters within the interior of the housing are mounted to a removable holder. A method of mounting a telecommunications module within a chassis.

A method of delivering an audio video asset is described. The method includes: receiving an order specifying an audio video asset to be delivered and a delivery destination for the audio video asset, wherein a delivery destination represents one or more physical delivery recipients; determining delivery paths representing different delivery technologies that could be used to deliver the audio video asset to the delivery destination; retrieving a set of path capacity timelines for the delivery paths, wherein path capacity timelines in the set of path capacity timelines each model a quantity of available capacity varying over time; processing the path capacity timelines to yield delivery path capacities; applying an allocation algorithm to the delivery path capacities to yield candidate delivery allocations, wherein candidate delivery allocations each includes one or more time periods during which one or more time periods a defined quantity of capacity can be allocated for delivery of the audio video asset; applying a cost function to the candidate delivery allocations to yield cost values, wherein the cost values each represent a cost of delivering the audio video asset according to the candidate delivery allocations; calculating scores for the candidate delivery allocations in dependence on a cost value for that candidate delivery allocation and one or more other objectives; selecting a candidate delivery allocation having a lowest score to yield a selected candidate delivery allocation; and delivering the audio video asset according to the selected candidate delivery allocation. Related apparatus and methods are also described.
摘要:
A fiber optic enclosure includes a housing and a cable spool assembly disposed on an exterior surface of the housing. The cable spool assembly has a first tear-away end and a second tear-away end. The first and second tear-away ends include at least one area of weakness extending from an inner diameter of the cable spool assembly to an outer diameter of the cable spool assembly. A mounting plate is rotationally engaged with the cable spool assembly such that the cable spool assembly and the housing selectively and unitarily rotate about an axis of the mounting plate.

A telecommunications assembly includes a chassis and a plurality of fiber optic splitter modules mounted within the chassis. Each splitter module includes at least one fiber optic connector. Within an interior of the chassis are positioned at least one fiber optic adapter. Inserting the splitter module through a front opening of the chassis at a mounting location positions the connector of the splitter module for insertion into and mating with the adapter of the chassis. The adapters mounted within the interior of the chassis are integrally formed as part of a removable adapter assembly. A method of mounting a fiber optic splitter module within a telecommunications chassis is also disclosed.
