Abstract:
A method of controlling a digital printing system includes updating information provided to a metadata packet. Information is provided in a metadata packet that is associated with a point of interest of a media. The location of the point of interest of the media is monitored as the media moves through the digital printing system along a media path. An operating parameter of the digital printing system is monitored. The initially provided information in the metadata packet that is associated with the point of interest is modified based on the monitored operating parameter of the digital printing system and the monitored location of the point of interest of the media.
Abstract:
In the gasification of granular solid fossil fuel in a reactor wherein the fuel forms a fixed bed moving from top to bottom of the reactor under gravity, oxygen-containing gases and water vapor are fed into the fuel bed through nozzles in the lower portion of the reactor, molten slag at a temperature of about 1350.degree. to 1500.degree. C. is discharged through a conduit which is inclined to the horizontal, and product gas is withdrawn from the reactor above the fuel bed, the improvement which comprises feeding oxygen gas into the reactor adjacent to the inlet of the slag discharge conduit and directed from above onto the molten slag, thereby forming a leakage gas at a temperature of at least about 1500.degree. C. which leakage gas is withdrawn through the slag discharge conduit co-current with the slag. The leakage gas is separated from the slag in a lock chamber and mixed with the product gas. The temperature and/or composition of the leakage gas in the slag discharge conduit may be used to control the rate at which leakage is produced. A corresponding apparatus is described. This simplifies slag discharge and prevents clogging.
Abstract:
An apparatus for gasifying solid fuels such as coal, in a packed bed by a treatment with a gasifying agent such as free oxygen-containing gas and water vapor under pressure, comprising a water-cooled reactor housing provided in its lower portion with gasifying agent inlet openings, a fuel distributor mounted on a vertical axis, a stirrer on a shaft disposed in the fuel bed in the upper portion of the reactor, and independent first and second drive means for independently rotating the fuel distributor and stirrer. Advantageously the distributor includes a hollow bearing shaft coaxial with the shaft of the stirrer and the stirrer shaft also has a bearing, a common bearing support cooperating with both of the bearings.
Abstract:
Coal such as caking coal is continuously gasified, with lump formation inhibited, under superatmospheric pressures and elevated temperatures by treatment with oxygen and water vapor and, if desired, additional gasifying agents in a reactor having a rotatable feeder which continuously feeds coal to be gasified and one or more stirrer arms which rotate in the upper portion of the coal bed. Each stirring arm is rotated at a peripheral velocity which is at least about 1 meter per minute at its end approximate the axis of rotation and at least 1.5 meters per minute at its end remote from the axis of rotation.The reactor for carrying out this process includes a rotatable feeder and one or more stirrer arms which rotate in the upper portion of the coal bed. Each stirrer arm extends from an axially extending body which has a diameter of from 0.3 to 0.7 times the inside diameter of the upper region of the reactor. The cross-sectional profile of each stirrer arm is preferably approximately an obtuse-angled triangle with the upper side of the triangle rising at an angle of 17.degree.-25.degree., the under side at an angle of 2.degree.-7.degree. and the trailing side at an angle of 60.degree.-80.degree. from the horizontal direction which is opposite to the direction of movement of the stirrer arm.
Abstract:
A method of controlling a digital printing system that uses multiple metadata packets is provided. A controller including a metadata channel is provided. Information in a first metadata packet that is associated with an initial point of interest of a media is provided by a primary metadata packet creation unit. The first metadata packet is inserted into the metadata channel of the controller. A second metadata packet including new information associated with a new point of interest of the media is created using a secondary metadata creation unit. The second metadata packet with the new formation is inserted into the metadata channel of the controller based on the location of the new point of interest of the media.
Abstract:
The invention concerns an electrical plug connector with an insulating contact carrier that contains a number of electrical contacts in the form of contact pins or contact sockets that are arranged parallel to each other, and which can be inserted axially into a plug connector housing, with the contacts being accessible from the front side of the contact carrier, and with the contacts having connecting elements on a rear side of the contact carrier for a connection with electrical power supply lines. The invention proposes to divide the plug connector housing in the insertion direction into a front and a rear housing section that are connected to a hinge joint by means of a swivel axle that is oriented orthogonally to the insertion direction. In a straightened operating position of the plug connector housing, the axially inserted contact carrier that at least partially engages the two housing section and is in lateral contact with said housing sections at least is some sections reliably prevents the swiveling of the housing sections and therefore the opening of the plug connector housing.
Abstract:
An electrical plug connector part with a locking nut that is rotatable relative to the plug body and can be screwed onto an associated matching plug part and that is secured against unintentional rotation relative to the plug body by matched latch elements, wherein first latch elements are rigid and are molded onto the locking nut, and corresponding second latch elements are mounted rotation-proof and with spring action on the plug body. The locking nut and the plug body of the plug connector part have an equal number N of first and second latch elements that are spaced from each other and are arranged in sequence in circumferential direction, with the first latch elements being located on an inner circumference of the locking nut, and the second latch elements being located on an outer circumference of the plug body. The spacing of the first latch elements is different than that of second latch elements. The N first and second latch elements do not follow each other directly, with the first latch elements specifically not forming a locking ring gear.
Abstract:
A method for selecting test site locations on a substrate, by a) specifying a subset of all test site locations on the substrate, and b) selecting a desired number of candidate test site locations from within the subset of test site locations on the substrate. c) While selecting one of the candidate test site locations and holding all others of the candidate test site locations as fixed, determining a new location for the selected one of the candidate test site locations, which new location increases a test sensitivity, as estimated by a trace of a variance-covariance matrix. d) Repeating step (c) for each candidate test site location in the subset of test site locations, to produce a finalized set of candidate test site locations, until a desired end point is attained.
Abstract:
Coarse-grained solid fuels in particle sizes of at least 2 mm are gasified under a pressure of 5 to 150 bars in a fixed bed which is slowly descending and into which the gasifying agents are introduced from below whereas the incombustible mineral constituents are withdrawn as solid ash or liquid slag from the lower end of the bed. Fine-grained solid fuels are gasified in a fluidized bed under a pressure of 1 to 100 bars. Oxygen, steam and/or carbon dioxide are used as gasifying agents for the gasification in the fixed bed and in the fluidized bed. The product gas from the fluidized-bed gasifier has a temperature of 700.degree. to 1200.degree. C. and is indirectly cooled with water. The resulting steam is fed as gasifying agent to the fixed-bed gasifier. The product gas from the fixed-bed gasifier can be indirectly cooled to produce steam and at least part of said steam is fed as gasifying agent to the fluidized-bed gasifier. The steam fed as gasifying agent to the fixed-bed gasifier has a temperature of about 300.degree. to 600.degree. C., preferably of about 400.degree. to 500.degree. C.The steam produced by an indirect heat exchange with the product gas from the fixed-bed gasifier can be superheated by an indirect heat exchange with the product gas from the fluidized-bed gasifier before said steam is fed as gasifying agent to the fluidized-bed gasifier.
Abstract:
Solid fuels are gasified in a fixed bed with gasifying agents passed through the fixed bed from below. The gasification residues are withdrawn as solid ash or as liquid slag under the fixed bed. The reactor is charged with solid fuels through a lock chamber and with tar through a supply conduit. The tar is delivered to the fuel in numerous individual streams, which are distributed over the cross-section of the fixed bed.In the gasifying reactor, an inclined distributor surface is disposed over the fixed bed and has numerous passage openings for the tar and the solid fuels. The outlet end of the tar supply conduit is directed to the upper portion of the distributor surface. A tar tub having outlet openings is associated with the distributor surface and serves to receive the tar. The distributor surface is rotatable on a vertical axis.
