摘要:
A manufacturing method, within a modularized manufacturing environment for stabilizing a phylon article that is produced utilizing a heat press, is provided. Initially, the method includes immersing a phylon article in a first tank, with a fluid disposed therein, and withdrawing the phylon article from exposure with the fluid. Typically, the midsole is heated from its production with the heat press when it is placed into the first tank. The immersion in the first tank acts to cool the phylon article, thereby stabilizing the heated phylon. The phylon article may be next placed in a second tank, with a fluid disposed therein, and withdrawn from exposure with the fluid. The fluid of the first tank may reside at a temperature comparable to or higher than the temperature of the fluid of the second tank. Recursively exposing the heated phylon article to the fluid of the tanks incrementally decreases the volume of the article.

Customized articles of footwear are produced by defining options that can be selected by a customer when submitting a custom order. These options typically include model options, functional options, and aesthetic options. These options are created by a design source, such as a shoe designer within a particular market, and presented to the customer when making the order. Upon a customer selecting one or more of the options at a user interface, the selected options are converted to specifications associated with the order. A work-load engine is employed to generate, based on the specifications, a work order that includes a dataflow for selecting appropriate stations on a manufacturing floor to participate in a manufacturing process, and a workflow for instructing each of the appropriate stations to perform a sequence of operations, within the manufacturing process, that result in fabricating individual components of the article of footwear according to the order.
摘要:
Shoes having midsoles with heel support, specifically designed to facilitate production via efficient shoe manufacturing methods and systems are described. In embodiments, the shoe upper is designed by way of a flat forming process. Additionally, in embodiments upper forms may be coupled with dual hardness midsole structures that provide heel support and eliminate the need for a heel counter in the shoe upper.

A premixed partial oxidation (POx) syngas generator is provided. The syngas generator includes a premixing device configured to mix a fuel stream and oxygen in a premixing region to form a gaseous pre-mix. The premixing device includes a fuel inlet configured to introduce the fuel stream within the premixing device and a flow conditioning device configured to pre-condition the fuel stream. The premixing device also includes an oxygen inlet configured to introduce oxygen into the fuel stream to facilitate premixing of the fuel stream and oxygen in the premixing region located downstream of the flow conditioning device. The syngas generator also includes a combustion chamber configured to combust the gaseous pre-mix from the premixing device to produce a synthesis gas enriched with carbon monoxide and hydrogen gas.

A pulse detonation combustor (PDC) assembly includes an upstream chamber forming an inlet plenum, a downstream chamber including a downstream portion of at least one PDC tube, and an integrated PDC head coupled to the upstream chamber and the downstream chamber. The integrated PDC head is configured to facilitate fuel injection and ignition within the PDC tube. The PDC tube includes an inner seal surface and an outer seal surface configured to mate with the inner seal surface, wherein the inner seal surface includes an elevated section thereon that engages with the outer seal surface such that the PDC tube is free to partially pivot about a longitudinal axis thereof.
摘要:
An aircraft engine is provided with at least one pulse detonation device, and the operational frequency of the pulse detonation device is varied over an operational range of frequencies around a mean frequency value. The pulse detonation device can be positioned upstream, downstream or adjacent to a turbine section of the engine. An additional embodiment of the present invention is an aircraft engine provided with more than one pulse detonation device, and the operational frequency of one, or more, of the pulse detonation devices is varied over an operational range of frequencies around a mean frequency value.
摘要:
A syngas turbine comprises a combustor for reacting a hydrocarbon fuel with at least one of an oxidant and steam at an elevated temperature and pressure to produce a synthesis gas enriched with carbon monoxide and hydrogen gas. A turbo-expander is in flow communication with the combustor for extracting work from and for quenching the synthesis gas.
