Abstract: Described is a method and a device for screen calibration for the true-to-original reproduction of surface colors, the spectral reflection distribution of which is known, wherein by setting parameters the screen can be influenced using software and an electronic controller in each partial region of the screen. The disclosure is characterized in that an observer adapts the reproduced color impression of the screen to the color impression of an original in each partial region of the screen, wherein the original is compared to the screen colors immediately thereafter on the screen surface and the screen parameters are varied until the color impressions of the original and of the screen appear identical to the observer on the respectively viewed partial screen, viewed from a predefined observer angle, and the settings performed are stored in a screen profile.

Abstract: A device for screening of outside light from the view of a video monitor is described. The device is constructed such that it may be fully or partially deployed, allowing for various configurations. In the fully collapsed configuration, the invention permits the user to employ the monitor without the light blocking shades as well. In a preferred embodiment, the device additionally includes a light source for illuminating the surface of the monitor.

Abstract: A rotatable separator drum includes a vertical rotating axis of rotation and at least one flow channel having an inlet opening and an outlet opening. Also included is at least one retaining dam arranged in the at least one flow channel in a region between the inlet opening and the outlet opening. The at least one retaining dam is configured to allow an overflow of liquid over the at least one dam and to provide for an accumulation of solids in front of the at least one dam. The at least one dam includes at least one rib arranged in a transitional region between opposing wall sections and a distributor base cover and the at least one rib includes portions having differing heights.

Abstract: The invention relates to a device for shading extraneous light and for creating defined lighting conditions on a monitor (9) and optionally on a pattern, having shading elements, comprising two side walls (2), a panel (5) and an upper part (3). The invention further comprises a base plate (1) and a device (4, 9.2) for preventing extraneous light to enter from the back and at least one light source (7) for illuminating a monitor surface. The invention is characterized in that at least some of the shading elements are designed to be movable and the at least one light source is integrated in the front region of the shading elements such that it does not illuminate the monitor after the shading elements are pushed back.
