摘要： The invention relates to an operating system for an externally operated part of a closing unit, in particular for a mold carrier of a closing unit. During operation, the entire closing unit (12) moves in a predefined first direction (D) and the externally operated part (18) can be moved between at least two positions. The externally operated part (18) includes a guide element in the form of a cam roller (22) which is moveable for reaching at least one of the positions in a predefined second position (A) by at least one operating unit (29) arranged separately to the closing unit (12). The operating unit (29) includes at least one gripper member (48) which grabs the cam roller (22) for moving the part (18) to the predefined second position (A) and moves it in this direction. To minimize wear, the gripper member (48) includes two freely moveable guide rollers (50) arranged in parallel relationship at a particular spacing from one another and having axes in substantial parallel or tangential alignment to the first direction (D). The spacing between both guide rollers (50) corresponds essentially to the diameter of the cam roller (22) or is slightly greater than the diameter of the cam roller (22), and the cam roller (22) is able to move into this spacing for moving the externally to-be-operated part (18) in the predefined second position (A) and subsequently is able to move out of the spacing.

摘要： A photographic processor wherein parallel webs consisting of photosensitive material and/or other material and having identical or different widths are transported lengthwise through one or more liquid baths each of which receives identical quantities of replenishment chemicals at a frequency which insures that the activity of the baths remains unchanged. The device which feeds replenishment chemicals is controlled by a circuit having two inputs one of which receives first signals at a frequency corresponding to the rate of transport of unit lengths of the webs through the bath or baths and the other of which receives cyclically second signals, one for each photosensitive web and each persisting for a period of time which is proportional to the width of the respective photosensitive web. The control circuit causes the feeding device to admit a predetermined quantity of replenishment chemicals in response to the generation of each first signal during the persistence of a second signal. First signals are generated on closing of a microswitch which is actuated by a loop former associated with one of the webs and moving up and down at a frequency which is proportional to the speed of the corresponding web. Second signals are generated by a photoelectric cell which is moved at a constant speed back and forth transversely of the paths of webs and whose transducer reacts only to light which is reflected by a photosensitive web.

摘要： A web of photographic paper is trained over several rollers so that it can be advanced along a meandering path through successive chambers in a developing machine. At least one of the rollers is mounted on a driven shaft with the interposition of a coupling which engages the shaft with the roller when the tension of the running web which is trained over such roller exceeds a certain value. The roller is normally held against rotation under the action of the web and/or under the action of the bearing which is rotatable on the shaft and yieldably maintains the roller in a position of coaxiality with the shaft. A braking device for holding the roller against rotation has a first plastic ring which is rotatably mounted on the shaft and is connected to or made integral with the bearing for the roller, and a second plastic ring which surrounds and is in frictional engagement with the first ring. The second ring is held against rotation with the first ring by a partition or by another stationary part of the machine.

摘要： Fluid is withdrawn from plural fluid-filled tanks via respective outflow conduits leading into a common mixing conduit which includes a mixing pump, and then branches off through respective inflow conduits for return of intermixed fluid back to the individual tanks. Each inflow conduit is provided with a valve unit comprising a vessel-like housing having an inlet port and an outlet port. The flow from the inlet port to the outlet port is regulated in dependence upon the height of fluid in the respective tank. The fluid height is sensed indirectly by sensing the height or pressure of fluid in the interior of the vessel-like housing, the latter being at least partly lower than the height of fluid in the respective tank. Thus, the return of fluid into each tank is regulated to maintain a respective fluid height therein independently of the other tanks.

摘要： A continuous processor for exposed webs of photographic paper has several tanks and a system of hoses which connect the outlets in the lower portions with the inlets in the upper portions of the tanks. The liquid developer is circulated by a pump and is heated by a heater before it reaches the inlets. The pressure of liquid in the system of hoses is monitored by two pressure responsive switches which cause a control unit to arrest the motor of the pump and to deactivate the heater when the pressure drops below or rises above a range of acceptable pressures. The pressure drops in response to leakage of developer, and the pressure rises in response to clogging of a filter which is installed in the system of hoses between the heater and the inlets of the tanks.

摘要： A continuous developing machine for exposed photographic material has a vessel with one or more outlets close to its bottom and one or more inlets at its top, conduits which connect the outlets with the inlets, a pump which circulates the developing solution from the outlets to the inlets, and a heating device which is installed in the conduits downstream of the pump and has a primary heater which is activated with a first delay whenever the temperature of developed solution downstream of the heating device drops below and is deactivated with a second delay whenever the temperature of developing solution rises above a preselected value, and an adjustable auxiliary heater which is actuated during each interval of admission of a liquid replenisher into the conduits upstream of the pump. The auxiliary heater is adjusted in dependency on changes in temperature and/or rate of admission of the replenisher. The temperature of the mixture of developing solution and replenisher is monitored immediately downstream of the heating device for the purpose of activating or deactivating the primary heater. A heat exchanger preheats the replenisher prior to admission into the conduits upstream of the pump.

摘要： An arrangement for transporting strip-shaped material, particularly photographic paper, includes a one-piece elongated holding element which extends along a triple-turn hairpin course to form four holding sections which are substantially parallel to one another and define with each other three spaces for strip-shaped material. Two brackets which are welded to the end portions of the two outer sections of the holding element and are bent at right angle to the remainder of the respective outer sections support the holding element on a conveyor belt for travel therewith. The four sections of the holding element resiliently contact one another to clamp the strip-shaped material therebetween when such strip-shaped material is received between neighboring sections.
