摘要:
The cathode region of a sodium sulphur cell has hitherto sometimes been sealed by a thin metal member welded at its outer periphery to the metal casing and at its inner periphery to the alpha alumina lid of the electrolyte. The welding operation damages the essential protective coating of the thin metal member. This invention discloses sealing the cathode region with a thin metal member (5) secured to a concentric outer thicker metal member (4), the thin member being sealed to the lid (15) and the thicker member being sealed to the casing (1). The thickness of the outer member eliminates the need for a protective coating so that the combined seal has greater integrity than previous seals.

A resource set comprising a set of resources may be provided to the public. It may be desirable to associate with the resources a set of public names, such as friendly URLs that may be more memorable, may indicate to users the type of resource so named, and may promote indexing of the resources by search engines. A name hierarchy (such as a portion of a file system) may store at least one reference that associates a public name with a resource. A name hierarchy navigation logic may facilitate navigation through the name hierarchy, and may specify a particular location within the name hierarchy where a reference associated with the public name is to be stored. This manner of associating public names with resources may promote the scalability and efficiency in associating public names with resources and in retrieving a resource associated with a particular public name.

Alkali metal energy conversion device comprising sealing components made of a metal or metal alloy substrate. A solid phase bonded coating of aluminum/silicon alloy is provided on an internal surface thereof. The aluminum/silicon alloy coating has the composition by weight of 0-0.5% Mg, 0-0.4% Cu, 0-1.0% Fe, 0.5-4.0% Si, up to 0.5% other trace elements, some oxygen present as an oxide and remainder Al.
摘要:
A sodium/sulphur cell includes a case and a closure member. Each of the case and the closure member is formed of a composite material consisting of a substrate and a deformable metal layer mechanically fixed to the substrate. The substrate is formed of a material which is harder than the deformable metal. An outwardly extending annular flange is formed at the open end of the case. The closure member is secured to the annular flange by a solid phase bond thereby to close the case.

A system for maintaining the operation of a work vehicle comprises a processing element in communication with a memory element. The processing element is configured to execute software components including a device abstraction layer component, a plurality of application programming interface components, a plurality of common machine layer components, and a state manager component. The device abstraction layer component is configured to send data to and receive data from physical components of the work vehicle. The application programming interface components are configured to adjust the data. The common machine layer components are each configured to provide control and monitoring of a physical component. The state manager component is configured to monitor a state of each common machine layer component.
