摘要： A web with overlays for use in the document presentation device of a photographic copying machine has several sheet-like sections with overlapping portions which are separably coupled to each other by snap fasteners and carry overlays which are welded thereto by the application of heat and pressure. The overlays are applied to those sides of the sections which are coated with layers of photographic emulsion.

摘要： An image consisting of a multitude of image points is formed by effecting relative transport between a plurality of light-emitting diodes and a recording medium. The diodes are arranged in rows. The rows are arranged successively in the transport direction. The rows extend at an angle relative to the transport direction. The diodes of each single row are offset relative to those of the other row, in direction transverse to the transport direction, by an amount equal to the distance between adjoining diodes in a single row divided by the number of rows, and/or multiples of that amount. Each diode is provided with an optical unit which projects onto the recording medium a reduced image of the light emitted by the diode. The diode-control signals corresponding to a single line of image points of the image to be formed are applied to the individual diodes with different respective time delays dependent upon the rate of transport and corresponding to the different distances among the rows as measured in the transport direction.

摘要： Relative movement is effected between a recording medium and a row of light-emitting diodes (LED's). The row of LED's extends parallel to the direction in which the line of image points to be formed extends, and transverse to the direction of relative movement. Reduced-scale images of the LED's are projected onto the line on the recording medium on which the line of image points is to be formed. The LED's and/or the optical units forming the reduced-scale images are oscillated in a direction parallel to the direction in which the line of image points to be formed extends. Each image of an LED sweeps a straight linear region on the recording-medium line at least equal in length to the distance between adjoining LED's of the LED-row. During each n.sup.th half-period of oscillation, a succession of control signals is applied to each LED, determining a succession of adjoining image points which the respective LED forms upon the recording-medium line in question; n is an integer. The resultant line of image points contains a number of image points equal to an integral multiple of the number of LED's in the row of LED's.

摘要： Apparatus for wet treatment of webs of photographic material has a series of chambers each of which defines an upper and a lower horizontal path for the transport of webs therethrough and a discrete liquid collecting tank below each chamber. Each chamber has an upper section above the upper path, a median section between the two paths and a lower section below the lower path, and each section has an inlet which receives liquid from the tank through the medium of a pump and an upright pipe which latter can constitute a support for the respective chamber. The liquid which issues from the inlet of the median section of a chamber is divided into two streams which respectively contact the undersides and upper sides of webs in the upper and lower paths. The upper sides of webs in the upper path are contacted by liquid issuing from the inlet of the upper section, and the undersides of webs in the lower path are contacted by liquid issuing from the inlet of the lower section. Each chamber allows the liquid to escape therefrom by flowing in and counter to the direction of transport of the webs, and such liquid is intercepted by guide members which direct the intercepted liquid into vertical ducts serving to return the liquid into the tank. The ducts are adjacent to the sides of the upper and lower paths and prevent the descending liquid from contacting the surrounding atmosphere.

摘要翻译： 用于湿处理照相材料幅材的设备具有一系列室，每个室限定用于输送纸幅的上部和下部水平路径，以及每个室下方的离散液体收集罐。 每个室具有在上路径上方的上部部分，两条路径之间的中间部分和下部路径下方的下部分，并且每个部分具有通过泵和直立管的介质从罐接收液体的入口， 后者可以构成对各个室的支撑。 从室的中间部分的入口发出的液体被分成两股，分别接触上下路径中的腹板的下侧和上侧。 上部路径中的腹板的上侧与从上部入口引出的液体接触，并且下部路径中的腹板下侧与从下部区域的入口排出的液体接触。 每个室允许液体通过流入和相对于幅材的输送方向而从其中逸出，并且这种液体被引导构件拦截，引导构件将截留的液体引导到将液体返回到槽中的垂直管道中。 导管与上下路径的侧面相邻，防止下降液体与周围大气接触。

摘要： An electrostatic copying machine wherein the copying drum and the cleaning unit for the photosensitive layer of the drum are mounted in the plastic casing of a module which can be inserted into the stationary main portion of the housing upon pivoting of a cover to open position. The main housing portion and the cover carry rollers which automatically center the copying drum of a properly inserted module when the cover is moved back to closed position. The casing of the module has a vessel for a supply of developing or fixing liquid and means for automatically feeding liquid to a tank in the main portion of the housing when the supply of liquid in the tank descends below a predetermined level. One of the rollers can be driven by the motor of the copying machine to rotate the drum when the latter is properly centered in the housing.
