Definitions

  • the invention relates to a device for developing microfilms, in which the exposed film successively passes through various workstations, such as developer bath, fixing bath, pre-watering, post-watering and drying, along a horizontally arranged path with the aid of a motor-driven pair of rollers.
  • workstations such as developer bath, fixing bath, pre-watering, post-watering and drying
  • an apparatus for developing microfilms in which the film to be developed passes through a consisting of guide rollers track and this Rol - lenbahn by further guide and deflection rollers to a closed path of an endless, driven belt , in particular a reinforced, chemical-resistant plastic film belt or similar conveyor belt, on which the film to be developed is attached to the inlet into the developer bath and is released therefrom before winding up the fully developed and dried film.
  • the microfilm to be treated runs through the individual baths, with the liquids washing around the microfilm on both sides.
  • the conveyor belt is held on a frame with all the rollers, the drive, the unwinding and the reeling bearing for the microfilm and can be inserted and removed with it in the individual baths or workstations.
  • This measure allows the development device to be taken apart in a simple manner, so that the individual baths or work stations and also the transport device can be cleaned or new bath liquids can be added.
  • the individual Bath fluids are exchanged and the baths are cleaned.
  • Special containers are required for dic discharge of used liquids and accordingly the fresh and unused liquids are transported and stored in their own containers.
  • the invention has for its object both to simplify the film guide system within the device and to improve and simplify the circuit with respect to the fresh and unused liquid and the used liquid to be discharged in such a way that half the number of transport containers is eliminated - a further object of the invention consists in reducing the dimensions of the bathrooms of the individual workstations and making the consumption of chemicals cheaper.
  • each vessel supplying a work station with a liquid and designed as a transport container has a feed pipe and a suction pipe, the suction pipe having the liquid via a liquid pump and a self-contained subsequent heating via pressure pipes leads to a bath of the assigned work station, in which it is sprayed against the horizontally running underside of the film and gets back into the vessel via a liquid and film guide body and the feed pipe.
  • the vessel serves at the same time as a transport vessel for the liquid in question and as a storage and supply tank in circulation for the respective bath of the work station.
  • the suction pipes are preferably guided via a pump provided with four suction and pressure chambers. This ensures that all baths are flowed through with the same amount of liquid per unit of time.
  • the heater is designed as a heat exchanger which, in a space filled with suarzsand and enclosed by a jacket, has a centrally mounted and axially running, electrically operated heating rod, which is surrounded by the pressure pipes.
  • This measure ensures that all baths are tempered evenly so that the liquids in all workstations have the same working temperature. It is advantageous to regulate the heating power of the heating element in which the pressure tube for supplying the first work stations has a temperature regulator. This is connected to a temperature sensor and when regulating the heating power on the basis of the temperature values determined, it is ensured that the same pressure is also applied to the other pressure pipes.
  • a motor-driven pair of rollers for the film transport is arranged in front of the first work station, so that a complex and complicated roller system is unnecessary.
  • the device shown in Fig. 1 is in a housing, not shown, the front flap in open state the vessels 2, 3, 4 and 5 releases.
  • the vessels 2 to 5 are designed as vessels that can be closed with a screw cap.
  • the vessel 2 serves to supply the work station 16 with developer solution and the vessel 3 contains a fixing solution to supply the work station 17.
  • the vessels 4 and 5 supply the work stations 18 and 19, which are used for preliminary and main watering and therefore contain appropriate watering agents.
  • Each vessel 2 to 5 is connected to a corresponding intake pipe 10, 11, 12 or 13.
  • the suction pipes lead to a liquid pump 14, which has four suction and four pressure chambers.
  • the pipes 40, 41, 42 and 43 running on the pressure side of the liquid pump 14 pass through a heater 15, which will be explained in more detail later with reference to FIG. 2.
  • the individual workstations 16, 17, 18 and 19 are constructed in principle in the same way, with the exception of an upper crosspiece, which will also be discussed in more detail later, so that it is also sufficient to understand the device if the workstation 16 is described in detail as an example . 3 is used at the same time.
  • the entire work stations including the drying station 47 are covered by a removable cover part 1 during the work process.
  • a liquid and film guide body 20 is arranged, which has an H-shaped cross section, the vertical supports 24 and 25 of which are on the floor 26 of the bath Support work station 16.
  • the distance between the vertical supports 24 and 25 is slightly smaller than the width of the film 31 (see FIG. 3).
  • grooves 33 and 34 extending in the longitudinal direction are provided in the vertical supports 24 and 25 above the crosspiece 32.
  • the crossbar 32 is provided with a central bore 35 directed towards the film surface, which is connected to the pressure tube 40.
  • the length of the liquid and film guide body 2U is less than the length of the bath of the work station 16, so that the developer solution flowing from the bore 35 onto the crossbar 32 reaches the bottom 26 of the bath and into the feed pipe 6, which is connected to the vessel 2. Since the length of the liquid and film guide bodies is less than the longitudinal extent of the baths, the film between the individual baths is completely exposed, so that the liquid is not carried over from one bath to the subsequent bath.
  • the grooves 33 and 34 in the vertical supports 24 and 25 are dimensioned such that the film 31 receives sufficient play.
  • the film 31 is approximately at a distance of 2 to - 3 mm out above the transverse web 32 so that an extremely small perfused with liquid space is available. This brings the underside of the film into intensive contact with the developer solution.
  • a transverse web 36 and 37 are located in the work stations 16 and 19 between the vertical supports 24 and 25 of the liquid and film guide bodies 20 and 23 above the film guide grooves 33 and 34.
  • a transverse web 36 and 37 are located in the work stations 16 and 19 between the vertical supports 24 and 25 of the liquid and film guide bodies 20 and 23 above the film guide grooves 33 and 34.
  • the rollers 45 and 46 are driven via gears 49 and 50 by means of a transmission 51 from the motor 52.
  • the transmission 51 also actuates the film winding roller 53 and two drying rollers 54 and 55 via its gears 56 and 57. No drive is required for the film reel 58, since the pair of rollers 45 and 46 unwinds the film from the roller 58 and this through the film guide grooves 33 and 34 pushes.
  • the heater 15 consists of an electric heating element 39, which is surrounded by the pressure pipes 40, 41, 42 and 43 at a distance. This room is filled with quartz sand, the is enclosed by the jacket 38.
  • the pressure pipe 40 is connected to a temperature controller 44 which controls the heating power of the electric heating element 39 with the aid of an electronic circuit.
  • the liquid pump 14 and the heater 15 are switched on, so that a continuous liquid circulation is already started before the film 31 is in the device.
  • the motor 52 is actuated and the film 31 is fed to the rollers 45 and 46, which grip it and guide it through the film guide grooves 33 and 34 of all liquid and film guide bodies 20 to 23. If the film reaches the liquid and film guide body 20, it cuts through the liquid flow, the upper transverse web 36 ensuring that a liquid space is also formed above the film. Since the film 31 has sufficient play in the grooves 33 and 34, the capillary action ensures that an adequate flow and thus renewal of the liquid is also formed. As already mentioned at the beginning, it is only necessary to provide upper transverse webs 36 and 37 if the upper side of the film is to be wetted. In the other cases, the upper crossbars can therefore be omitted.
  • Vessels 2 to 5 perform three different functions. So they serve once for the transport of the still fresh liquid, form a storage tank within the device, which is located in the circuit of the respective liquid and also serve for the removal of the used liquid. Compared to the previously known devices, half the number of vessels is therefore eliminated. A laborious cleaning of the storage tanks is no longer necessary. Within the workstations there is the advantage that they can be dimensioned relatively small because of the intensive flow circulation, but still a constant effect on the film is achieved. Overall, this has the advantage that the device according to the invention can be used not only in the usual laboratories, but also in other rooms that do not have any special facilities, as are customary for laboratories, since no contamination can occur due to any cleaning processes .
