摘要： The photographic copying apparatus comprises a first exposure arrangement for exposure of photographic negative and positive copy masters and a second exposure arrangement for exposure of screen copy masters onto photographic copy material. The second exposure arrangement includes a cathode ray tube with control system. The cathode ray tube is arranged at approximately a right angle with respect to the exposure light path of the first exposure arrangement. The second exposure arrangement further comprises a color filter assembly, an objective and a mirror for directing the screen copy master emitted by the cathode ray tube to the photographic copy material. The color filter assembly, the objective and the mirror are combined as a structural unit to constitute an imaging optical system, which can be positioned into the exposure light path instead of an reproduction objective of the first exposure arrangement.

摘要： A draft protection device for a balance, which encloses a weighing compartment surrounding a weighing pan, has at least one opening that can be closed by a window. The at least one window has at least two slidable window sections which partially overlap each other in any of their positions. According to the invention, a drive mechanism is provided for the opening and closing of the window, which drive mechanism couples the window sections to each other in such a way that all of the window sections move simultaneously and at different speeds during the opening and closing, wherein a fixed ratio between the respective speeds of the window sections can be predetermined by design.

摘要： A balance (1, 101) has a draft protection device (2) that encloses a weighing compartment surrounding the weighing pan (15). A rear wall (22, 122) delimiting the weighing compartment on one side is made of a material (26) that diffuses the transmitted ambient light. The translucent, light-diffusing material (26) is in particular a frosted glass.

摘要： Disclosed is a photographic capturing device for the capturing of photographic image information from photographic media with a light source, with a stage for the photographic medium to preset a reference position for the projection of the photographic medium by way of a projection optics onto a detection element which detects the light originating from the light source and modulated by the photographic medium according to the image information, whereby a sample carrier with a sample is provided for the control of the focus of the projected image, and a positioning mechanism which removably places the sample carrier at the reference position for projecting the sample onto the detection element by way of the projection optics.
