摘要： A driving arrangement for filters, shutter blades or analogous light-obstructing elements of photographic cameras or photographic printing apparatus comprises an electromagnet having an armature which is turnable within a predetermined angle to turn a one-armed lever which is rigid with the light-obstructing element. The motion transmitting connection between the armature and the lever comprises a gear segment on the armature, a gear provided on an intermediate shaft which carries a crank arm, and a pin-and-slot connection between the crank arm and the lever.

摘要： A photographic copying machine wherein the copying station is located between two feeding stations for a web of photographic material. The web is guided by fixedly mounted and pivotable guide members which define at each feeding station an opening through which loop-shaped intermediate portions of the web can enter a basket-shaped magazine. Two intermittently driven wheels at the first feeding station draw the web from a supply cassette and feed it directly into the adjacent magazine from which the web is withdrawn by intermittently driven wheels at the second feeding station whereby the web enters the other magazine from which it is withdrawn in response to rotation of the takeup reel in a second cassette. Pivotable flaps can seal the magazines from the path for the web during threading of the leader of a fresh web into the copying machine, and forked intercepting devices are provided adjacent to the magazines to intercept folded-over portions of the web.
摘要翻译：一种照相复印机，其中复印站位于用于照相材料幅材的两个供给站之间。纸幅由固定安装和可枢转的引导构件引导，引导构件在每个进给站处限定了一个开口，通过该开口，卷筒纸的环形中间部分可以通过该开口进入篮形盒。在第一馈送站的两个间歇驱动的轮子从供应盒中抽出纸幅并将其直接送入相邻的盒中，在第二馈送站中间隔地驱动纸卷从纸幅中取出纸幅，由此纸幅进入另一盒响应于收起卷轴在第二盒中的旋转而撤回。透视襟翼可以在将新鲜卷筒的引导件穿入复印机的过程中将纸盒从用于卷筒纸的路径中密封，并且在杂志附近提供叉形截取装置以拦截卷筒纸的折叠部分。

摘要： An arrangement for controlling the exposure times of duplicators. In addition to the light source used for carrying out the exposure, a constant light source is used for applying the light to the photoelectric device in the duplicator, when the duplicator is not in use, for the purpose of maintaining the photoelectric fatigue effect constant. The constant light source is also used for calibrating the controlling circuitry for the exposure time. A timer connected to the switching circuitry which establishes the exposure interval gives an indication of the measured time interval. Adjustable resistors permit settings and compensations for the varying characteristics of the duplicating paper, as well as the characteristics of the individual duplicating machines.
摘要翻译：用于控制复印机的曝光时间的装置。除了用于进行曝光的光源之外，为了维持光电疲劳效应的目的，当复印机不使用时，使用恒定的光源将光施加到复印机中的光电装置。恒定光源也用于校准曝光时间的控制电路。连接到切换电路的建立曝光间隔的定时器给出测量的时间间隔的指示。可调节电阻器允许对复印纸的变化特性以及各个复印机的特性进行设置和补偿。

摘要： Light is transmitted through the original onto photosensitive material in each of three primary colors. Three secondary electromultipliers furnish electrical currents which vary as a function of the light received by the photosensitive material in each color. Each current is integrated by a capacitor, the voltage on the capacitor compared to a reference voltage, and a relay energized when the capacitor voltage and the reference voltage have a predetermined relationship. Each relay has a first set of contacts for terminating the illumination in the corresponding color and a second set of contacts for shorting out part of a resistance connected in series between the supply voltage terminal and a transformer supplying voltage to the secondary electron multiplier corresponding to the other colors. This increases the sensitivity of the other electron multipliers, increasing the charging rate of the capacitor, and thus decreasing the exposure time in the other colors.

摘要： A web of photographic paper is provided with indicia in the form of parallel grooves which are impressed into the rear side of the web by a reciprocable or pivotable ram- or wheel-shaped tool having one or more projections in the form of teeth, ribs or rings. The grooves are deep enough to be detectable by a needle, elastically mounted blade or other mechanical scanning means which cooperates with a transducer serving to produce signals for actuation of a device which severs the web between neighboring prints or for actuation of an evaluating circuit which receives a signal upon detection of the last print forming part of a customer order. The grooves extend at right angles to the longitudinal direction of the web. The projections of the tool can be heated to insure the formation of lasting grooves even if the web is caused to pass through one or more liquid baths before it reaches the scanning station.

摘要： CONTROLLED REPRODUCTION OF UNDERCORRECTED IMAGES OF COLOR PHOTOGRAPHIC NEGATIVES ON PRINT MATERIAL WHICH IS SENSITIZED IN THE PRIMARY COLORS IS ACHIEVED BY DEFLECTING THREE SECONDARTY LIGHT BEAMS FROM A BEAM OF WHITE LIGHT ISSUING FROM A PRINTING LAMP AND PASSING THROUGH A NEGATIVE TOWARD THE PRINTING STATION, BY PLACING INTO THE PATH OF EACH SECONDARY LIGHT BEAN A COMBINATION FILTER WHICH INCLUDES A COLOR FILTER CAPABLE OF PERMITTING PASSAGE OF LIGHT IN ONE OF THE PRIMARY COLORS AND A GREY FILTER SO THAT SOME LIGHT PASSES THROUGH THE COLOR FILTER AND THE REMAINDER OF THE LIGHT PASSES THROUGH THE GREY FILTER, DIRECTING THE THUS MIXED LIGHT AGAINST SECONDARY ELECTRON MULTIPLIERS, AND UTILIZING SIGNALS PRODUCED BY THE MULTIPLIERS TO CONTROL THE DURATION OF EXPOSURE OF PRINT MATERIAL TO LIGHT IN THE RESPECTIVE PRIMARY COLORS.
