Abstract: For printing to a recording medium in the form of a web that is moved in a horizontal direction to the printing position by a web carriage. There, the recording medium is raised up to the print heads. To clean the print heads, a maintenance carriage is used that is moved horizontally into a maintenance position below the print bars. There, a cleaning unit with covering caps is then driven upward to the print heads in order to either place a covering cap onto the print heads or clean the print heads. The web carriage and the maintenance unit are moved only in a horizontal direction while the printing unit remains stationary.

Abstract: A device for generating an output signal, formed as a pulse sequence, with a sensor and a controller. The sensor generates a sensor signal based on a measurand determined by the sensor. The controller determines a number of pulses of a timing signal that are generated chronologically between two pulse edges of the sensor signal, the timing signal being generated by a timing signal generator. The controller also generates an intermediate timing signal formed as a pulse sequence, where the period duration of the intermediate timing signal is equal to the period duration of the timing signal multiplied with a factor that is equal to the determined number of pulses of the timing signal, divided by a predetermined divisor. The controller generates the output signal based on the intermediate timing signal.

Abstract: Aspects of the disclosure relate to a method and a compensator via which the input edges of the encoder signal of an encoder may be transformed into a compensated encoder signal such that requirements with regard to a dot resolution of a printing device and with regard to a maximum activation frequency of the dot generators of the printing device are satisfied.

Abstract: In a method for determining a print quality of an inkjet printing system, at least one artifact filter is applied to print data to identify a partial region of a print image to be printed in which a print image artifact may be present in the actual printed print image. The print quality of the inkjet printing system can then be determined based on the identified partial region.

Abstract: A method for stabilizing a print quality in an inkjet printing system is described. The inkjet printing system can include a nozzle arrangement that may be activated with a number of control signals that can be used to fire ink droplets with corresponding different droplet sizes onto a recording medium. In the method for stabilizing a print quality in an inkjet printing system, a rastered image for an image template can be created. The rastered image can be printable by the inkjet printing system using a subset of the different droplet sizes. Further, the nozzle arrangement can be activated with a control signal for an unused droplet size of the different droplet sizes to induce the nozzle arrangement to generate a prefire pulse.

Abstract: In a method to determine concentration of toner particles in a carrier fluid in a liquid developer system for a printer or carrier, a suspension of the carrier fluid in the toner particles is charged with an ultrasonic wave. A propagation time of the ultrasonic wave in the suspension is determined. A concentration of the toner particles in the suspension is determined from the propagation time. A system is also provided employing the above steps.

Abstract: In a method to determine concentration of toner particles in a carrier fluid in a liquid developer system for a printer or carrier, a suspension of the carrier fluid in the toner particles is charged with an ultrasonic wave. A delay of the ultrasonic wave in the suspension is determined. A concentration of the toner particles in the suspension is determined from the delay. A system is also provided employing the above steps.

Abstract: In a method for control of an electrophotographic printer or copier, information that refer to a single sheet are determined from print data supplied to the printer or copier. Dependent on said information, a transport path of the single sheet through the printer or copier to generate at least one print image on at least one side of the sheet is determined. A system time of the printer or copier is provided that is the same for at least first and second control units of the printer or copier. At least one desired point in time at or until which at least one sensor signal is expected or at least one actuator is activated is established dependent on the transport path, the desired point in time referring to the system time of the printer or copier.

Abstract: Bone replacement parts consisting of glass ionomer cement are superior to those made of ceramics especially since they may easily be produced and machined using common grinding and milling tools. The required prosthesis part may therefore be formed of freshly mixed glass ionomer cement during the respective operation, or an industrially prefabricated formed body approximating the idealized shape of the bone part to be replaced may be adapted to the anatomic conditions given.

Abstract: An implantable active substance depot material which contains a glass ionomer cement and one or more chemotherapeutic agents. The active substance depot materials ensure an initially high release rate of the active substance therein and subsequently a discharge of the active substance in small doses until complete depletion of the deposited active substance has occurred.

Abstract: Curable compositions are described which contain a binder and a high propion of fillers having a mean grain size of <50 .mu.m. The filler proportion of the curable compositions is so high that they cannot be used for the intended purpose because of their high viscosity However, they can be liquefied by exposure to oscillation in the frequency range of 20 Hz to 20 MHz with an amplitude of 1 .mu.m to 5 mm so that they are workable and can be employed for the intended purpose.

Abstract: The invention relates to the use of glass ionomer cements in a method of guided tissue regeneration. In the method, cavities are artificially created by forming glass ionomer cement coverings over bone substance defects, so that osseous regeneration can take place without a growing-in of connective tissue or bacteria colonization occurring in the bone defects.
