摘要:
A system for removing packing coke from baking chambers of a furnace for baking carbon bodies includes a crane mounted for movement along a rail, a silo supported by the crane, a suction tube connected to the silo and insertable into packing in a furnace baking chamber, and structure for supplying vacuum to the suction tube to remove the packing coke therethrough from the chamber into the silo. The vacuum structure includes a closed vacuum duct extending parallel to the rail, the vacuum duct having an upper slide surface and a plurality of valves spaced along the slide surface. A stationary vacuum source is connected to the vacuum duct and creates therein a vacuum. A sliding box is supported by the crane and is movable thereby along the vacuum duct over the valves on the slide surface. Each valve is openable by a respective pneumatic cylinder. An activating rail is mounted on the sliding box and is operable upon movement of the sliding box along with vacuum duct to activate the pneumatic cylinders to open respective valves, thereby communicating the vacuum from the stationary vacuum source through the vacuum ducts, the opened valves and the sliding box to the silo and the suction tube. The sliding box has supporting wheels rolling on the vacuum duct and guide wheels positioning the sliding box on the vacuum duct. The sliding box has a sliding gasket sealingly contacting the slide surface. The sliding gasket includes a rubber skirt into which is fitted an elastic gasket of a material with a low coefficient of friction and sliding along the slide surface.

Methods and systems for content initiation are described. In one embodiment, execution of an executable application is initiated. The executable application is associated with source code of a gaming application and a compiled version of a gaming application. Advertising data is received through a network. The source code of the gaming application is recompiled using the advertising data to create a recompiled version of the gaming application. Game play of the recompiled version of the gaming application is initiated. The game play includes presentation of advertising based on at least a portion of the advertising data. Additional methods and systems are disclosed.

A collapsible container includes a cylindrical sidewall extending between a top and a bottom of the container. The sidewall is formed of a flexible material which enables the container to be opened to an expanded configuration or closed to a collapsed configuration. A coil spring biases the container to the open configuration. The coil spring has a top coil adjacent the top of the container and a bottom coil adjacent the bottom of the container. A durable bottom layer is affixed to the bottom of the container.

A suction tube unit for removing packing coke from vertical spaces within a ring furnace for producing carbon bodies includes a plurality of elongated suction and air supply tubes, the tubes being arranged to extend parallel to each other and being aligned in a single straight row, with each adjacent pair of the suction tubes being separated by a separate one of the air-supply tubes, thus forming an elongated assembly adapted to fit within the vertical space of the furnace. The assembly is supported at an upper portion thereof by a telescopic mounting. All of the tubes are open at lower ends thereof. A suction device is connected to the upper end of the suction tubes for creating a vacuum within the suction tubes to thereby withdraw the packing coke therethrough. Upper portions of the air-supply tubes have therein orifices to supply ambient air into the air-supply tubes and to aid in withdrawal of the packing coke through the suction tubes.
摘要:
A method is described for forming a memory structure using a hardmask (65). The hardmask (65) protects the second polysilicon layer (55) during a SAS etch process. In addition, sidewall structures (95) are formed which protect the inter-polysilicon dielectric layer (45) during the hardmask (65) etch process.

A device for removing weeds from the ground comprises an elongated shaft, a handle mounted to an upper end of the shaft, a pair of blades mounted for opposed pivotal movement at a lower end of the shaft, and a plunger. Each blade has an upper section located above a pivot point of the blade and a lower section located below the pivot point. The plunger is mounted for reciprocal sliding movement between an extended position intermediate the lower sections of the blades and a retracted position intermediate the upper sections of the blades. The plunger and the upper sections of the blades include cam surfaces configured such that movement of the plunger from the extended position to the retracted position forces the upper sections of the blades away from one another, whereby tips of the blades are forced to converge towards one another to capture the weed and accompanying root structure. The weed and surrounding soil plug can be released by squeezing a hand-lever.
