摘要:
Silicon deposits are suppressed at the wall of a fluidized bed reactor by a process in which an etching gas is fed near the wall of the reactor. The etching gas includes tetrachlorosilane. A Siemens reactor may be integrated into the process such that the vent gas from the Siemens reactor is used to form a feed gas and/or etching gas fed to the fluidized bed reactor.
摘要:
A communication resource system and method for determining communication product capacity in a communication network based on the physical capacity of individual network components. The communication resource system compiles spare capacity information for the individual network components into information on a quantity of communication products that may be provided based on the capacity available on the individual network components. The communication resource system includes a processing coupled to an interface system. The processing system is configured to process equipment capacity information and circuit capacity information to generate the product capacity information. The interface system is configured to receive the equipment and circuit capacity information and provide the product capacity information for the processing system.

Ethylene/carboxylic acid ionomers may be made, using a meltspun, and particularly meltblown process, into microfibers and thence to filter webs which are efficient gas filters for removing particles having a diameter of from 0.5 to 20 microns from a gas. The webs are effective without a deliberate specific post-charging operation during production. A deliberate post-charging operation can also be carried out to result in further efficiency.

A steering arrangement for construction vehicles and the like comprises a steering column assembly pivotally mounted on a stationary support for selective adjustment about a pivot axis disposed transversely relative to such assembly. A steering handle, rotatably mounted on the assembly, is operatively connected to a steering valve by linkage means for selectively steering a vehicle in response to rotation of the steering handle. The linkage means includes a push-pull cable having its upper end pivotally mounted about a pivot axis coincident with the pivot axis about which the steering column assembly is pivotally mounted on the stationary support to prevent actuation of the steering valve upon adjustment of the steering column assembly.

A method for recharging a crucible with polycrystalline silicon comprises adding flowable chips to a crucible used in a Czochralski-type process. Flowable chips are polycrystalline silicon particles made from polycrystalline silicon prepared by a chemical vapor deposition process, and flowable chips have a controlled particle size distribution, generally nonspherical morphology, low levels of bulk impurities, and low levels of surface impurities. Flowable chips can be added to the crucible using conventional feeder equipment, such as vibration feeder systems and canister feeder systems.

A method inhibits formation of deposits on a cooling surface of an electrode. The electrode is used in a manufacturing system that deposits a material on a carrier body. The cooling surface comprises copper. The system includes a reactor defining a chamber. The electrode is at least partially disposed within the chamber and supports the carrier body. A circulation system, in fluid communication with the electrode, transports a coolant composition to and from the cooling surface. The coolant composition comprises a coolant and dissolved copper from the cooling surface. A filtration system is in fluid communication with the circulation system. The method heats the electrode. The cooling surface of the electrode is contacted with the coolant composition. The material is deposited on the carrier body, and the coolant composition is filtered with the filtration system to remove at least a portion of the dissolved copper therefrom.

An object oriented date and time control in a graphical user interface of a computer system is composed of a plurality of child objects, e.g., spin buttons. Changes to the children of the control are consolidated in a massaging mechanism which includes a message format including a control identifier of the control and a name of the detected change. In this way, the owning application does not have to monitor element of the control separately. Each child object has a range of allowed values which the user may select. The child objects interact such that a range of allowed values in one child object, the child object which sets the day value, is set according to the value for another child object, the child object which sets the month value. Responsive to changes in the month value, the range of allowed values for the day value may change accordingly. The date and time control is sensitive to locale or country specific data. In response to a given locale for the owning application, the order of the day, month and year elements of the date control and the 12 hour or 24 hour modes of the time control may be set compatibility to the conventions of the given locale.

A basic cab unit, mounted on the frame of a construction vehicle such as a wheel loader, comprises a substantially flat rear panel having a generally rectangular opening formed therethrough. The opening is defined by a plurality of mounting flanges adapted to have the mounting flanges of a window unit secured thereto. In a first embodiment of this invention the window unit, having mounting flanges extending outwardly therefrom, is secured to the mounting flanges of the basic cab unit along with flanges formed on a roll-over protection structure (ROPS). The latter structure further comprises a reinforced canopy which extends over a top panel of the basic cab unit. In a second embodiment of this invention a window unit constitutes the sole component secured to the basic cab unit by flanges formed thereon to extend inwardly towards each other.
