The printing device includes a purge tray, the purge tray being configured to, in a purging operation, collect fluid purged from the print unit, and a recording medium transport unit configured to transport the recording medium in a transport direction. The print unit has a length extending in a printing range direction, the printing range direction being perpendicular to the transport direction. The purge tray has a length extending in the printing range direction, the length of the purge tray being smaller than the length of the print unit. The purge tray is configured to, in the purging operation, move underneath the print unit in the printing range direction.

Abstract: The disclosure relates to a method for avoiding contamination of a printing plate given surface-covering coating of a dust-forming recording medium (e.g. an uncoated paper) with a coating substance (e.g. a primer) in an inkjet printing operation. The method can include feeding the recording medium at a feed velocity that is greater than 20 meters per minute; continuously printing of the coating substance onto the recording medium by at least one print head including a plurality of print nozzles, the coating substance being printed at a constant, predetermined applied quantity per area. A nip between the print head and the recording medium is provided such that a fluid-dynamic eddy is created between the recording medium and the print head and/or the printing plate. The disclosure also related to a printing system that is configured to implement the method.

Abstract: In a method for preventing or reducing air vortex formation between a print plate and a recording medium upon printing to the recording medium with a coating substance (e.g. primer), the recording medium is provided at a feed velocity of at least 20 meters per minute, and a plurality of print nozzles of a print head are alternately activated to print the coating substance on recording medium to cover a surface of the recording medium with the coating substance. The activation can include only activating a portion of the plurality of print nozzles simultaneously. Further, a predetermined applied quantity of the coating substance per area is constantly printed onto the recording medium.

Abstract: Methods for displaying advertisements on a computer are provided. One method includes: detecting keyword information from a source module with a data processor wherein the keyword information is visible to a user on a display component of the computer; comparing the keyword information to a keyword database wherein the keyword database associates the keyword information with one or more keywords; comparing the one or more keywords to an advertisement database wherein the advertisement database associates the one or more keywords with one or more advertisements; and displaying the one or more advertisement on the display component through a sidebar module, wherein the sidebar module is viewable by the user independently of the visibility of the source module. The advertisements may be ranked according to perceived user benefit and/or social-media popularity. Associated computer program products and advertisement display systems are also provided.

Abstract: The invention is a method for delivering targeted web advertising to internet users via a network capable of rating, annotating, linking, meta-tagging and otherwise annotating any definable data accessible through a global computer network. The system is comprised of a graphical user interface (GUI), a database, and software to connect the two. The system stores and caches data and related annotations in a database. The software searches and organizes the database inputs. The GUI displays the result to the user. The user, through a web-browser or other means, would access a definable set of internet data (e.g., a web page) and through the proposed system be able to view ratings of that data as well as other relevant inputs from other users.

Abstract: This disclosure relates to novel adhesive compositions and composite structures utilizing the same, wherein said adhesive compositions contain an elastomer, a chemically compatible ethylenically unsaturated monomer, a tackifier, an adhesion promoter, and optionally, pigments, fillers, thickeners and flow control agents which are converted from the liquid to the solid state by exposure to high energy ionizing radiation such as electron beam. A particularly useful application for such adhesive compositions comprises the assembly of certain composite structures or laminates consisting of, for example, a fiber flocked rubber sheet and a metal base with the adhesive fulfilling the multiple functions of adhering the flocked fiber to the rubber sheet as well as adhering the rubber sheet to the metal base.
