Abstract: A fluid pumping assembly for pumping particulate material includes a pump housing defining a pump cavity including a pumping chamber for handling particulate material, a motive fluid chamber, and a moveable diaphragm. The fluid pumping assembly also includes devices for loading particulate material into the pumping chamber, and for injecting a high pressure, high volume purging fluid into the pumping chamber. Further, the fluid pumping assembly includes a control system having a control valve for shutting off flow of high pressure, high volume purging fluid into the pumping chamber when particulate material is being loaded into the pumping chamber, thus enabling dense phase loading of particulate material, and thereby optimizing a particulate material pumping capacity of the fluid pumping assembly.

Abstract: Gyricon balls are provided with magnetic pads that allows them to be located into two different positions by means of a further stationary magnetic pad. The magnetic pads are engulfed and sequestered from sight so they do not decrement the brightness of the display. The magnetic pads are made by dispersing magnetic pigments into the polyethylene plastic. The addition of aluminum octoate to one hemisphere of the gyricon ball causes the pigmented plastic on that side of the ball to attempt to envelope the pigmented plastic on parts of the ball that does not have aluminum octoate added during the ball making process.

Abstract: A digital printing system (10) includes a method to request and receive customized job status information. A document assembly tree (300) is extended to include the ability to enter status report frequency specifications at a compilation node (310), or at any other node, such as an intermediate sheet node (330) or sub-compilation node (342). The method consumes less control bus (31) bandwidth than other systems by providing only the required information at a configurable interval.

Abstract: A method and system compensates for the line width growth or shrinkage in an image rendering system that supports high-addressability. The amount of width adjustment can be a function of the line width. The method is applied after rendering, to the sub-pixel, bit patterns and is compatible with antialiasing and other sub-pixel rendering techniques such as half-bitting. The method and system also require less scan buffering for marker line width compensation than conventional methods. More specifically, the method and system require N+3 scans to detect and adjust widths up to N pixels for leading edges or trailing edges rather than the 2N+3 necessary conventionally. Moreover, the detection and adjustment of widths up to N pixels may be performed for both leading edges and trailing edges using a buffer that can handle 2N+3 scans.

Abstract: A concentration sensor 11y and a level sensor 12y measure the toner concentration and the volume of a developing solution in a storage tank 3y. A carrier feed pump 6 and a toner feed pump 7y are driven and controlled in real time based upon values detected by the sensors 11y and 12y during the printing operation, in order to feed a concentrated toner or a liquid carrier into the storage tank 3y to maintain the volume and the toner concentration of the developing solution in the storage tank 3y within predetermined ranges. The concentration and the volume are adjusted in real time during the printing operation which therefore needs not be interrupted for adjusting the developing solution. This makes it possible to continue the printing operation for extended periods of time.

Abstract: A developer circulation system includes a storage tank which stores a developer, a development device, a developer supply passage through which the developer is supplied to the development device from the storage tank, a developer return passage through which the developer is returned to the storage tank from the development device, a circulation pump, and an agitation member which agitates the developer in the storage tank. An outlet of the developer return passage and an opening of the developer supply passage are located in the storage tank, so as to promote a flow of the developer generated by the rotation of the agitation member, at positions furthest from each other along a flow of the developer from the outlet of the developer return passage and the opening of the developer supply passage.

Abstract: The present invention presents an image processing apparatus that performs rotation, enlargement, reduction, clipping or overlapping processing of images at high speed using low capacity memories instead of page memories and without the need to read image data in repetition. A first band data storing element receives input image data line by line and stores it as local data. The local data stored in the first band data storing element is transformed by local data transforming element and then stored in a transformed data storing element. The local data is then read in the order it is to be output and stored in a second band data storing element. An image output element then outputs the local data as an output image.

Abstract: When a thermoplastic spacer is applied to a glass pane in the production of insulating glass panes, the nozzle from which the plastic with the desired cross sectional shape is extruded along the edge of the glass pane. The speed with which the plastic is applied along the edge of the glass pane is chosen depending on the temperature of the plastic. Here, for a stipulated temperature setpoint the speed with which the plastic is applied along the edge of the glass pane is stipulated. If the temperature increases, the speed is increased; conversely, when the temperature drops below the setpoint, the speed with which the plastic is applied along the edge of the glass pane is reduced. This ensures that the correct amount of thermoplastic is always extruded onto the glass pane and a spacer with a uniform cross section is obtained.

Abstract: A fluid-filled heat sink is positioned on the emission surface of a laser diode. The light beam emitted by the laser diode aperture will propagate though the optically transparent fluid to be transmitted through an output window of the heat sink. Heat generated by the laser diode will be transferred by the thermally conductive fluid to the heat sink housing which will radiate the heat or transfer the heat to a secondary heat sink.

Abstract: A security control system for remote computers includes a first local input/output device for entering a user name and regular password. A password generator (10) returns a single-use password which is an encrypted combination of the user name, a representation of the regular password, and date and time information. A second local input device is used for entering the single-use password. A remote computer (50) receives the single-use password. The remote computer (50) has a cache (76) of previously received single-use passwords. The remote computer (50) compares the single-use password to the cache (76) of previously received single-use passwords. If there is a match further access is denied. Also included is a decryption key (78) which is used to regenerate the user name, the representation of the regular password, and the date and time information. If the date and time is older than a predetermined date and time threshold further access is denied.

Abstract: An improved method of upgrading an image transfer engine such as, for example, an ink jet fluid printer or plotter using liquid ink, or a xerographic device using a liquid toner is disclosed. A removable ink flush tank/cartridge containing an ink cleaner is substituted for a removable ink tank, permitting complete cleaning of ink from the ink fluid flow paths in the engine. This results in less contamination of new inks with previously used inks in the engine.
