    摘要： Disclosed are apparatuses and methods for forming films having uniform thicknesses across the entire width of the film. The films are also disclosed. The apparatus for forming the film includes a first nip roller and a second nip roller, each of the first nip roller and the second nip roller being configured to compress the powder as it passes between the first nip roller and the second nip roller and thereby form the film, whereby in the absence of a force counteracting the pressure of the passage of the powder between the first nip roller and the second nip roller the first nip roller is deflected to a greater degree than the second nip roller. Furthermore, the first nip roller and the second nip roller are each associated with one or more eccentric bearings that rotate to apply force vectors to the first nip roller and the second nip roller.

    摘要： A marking system includes a valve body including an orifice plate including multiple orifices and multiple micro-valves. Each micro-valve includes an actuating beam movable from a closed position in which a corresponding one of the orifices is sealed by a portion of the actuating beam such that the micro-valve is closed, into a peak position in response to application of a control signal. A controller is configured to generate a control signal for each of the actuating beams, each control signal including a drive pulse having a predetermined voltage such that the actuating beam moves from the closed position into the peak position in which the corresponding orifice is open and returns to the closed position in a characteristic period, wherein the drive pulse has a duration that substantially corresponds to the characteristic period such that the actuating beam is in the closed position after the drive pulse is complete.

    摘要： A torque support for absorbing drive torques of at least one shaft drive, having two first force-conducting elements, each of which is rotatably fixed to the shaft drive at a distance from one another by a first end, and having a support element arranged at a distance from the shaft drive, to which support element the first force-conducting elements are each fixed rotatably and at a distance from one another by a second end opposite the first end, and spaced apart from one another, and having two second force-conducting elements which are each fixed at a first end to the support element in a rotatable manner and spaced apart from one another and are each fixed at a second end, opposite the first in each case, to a fixed element which is independent of the shaft drive in a rotatable manner and spaced apart from one another. A corresponding roller arrangement is further disclosed.
