摘要： The level of chemical treatment baths is automatically, compensated, in film developing machines. A vessel (90) contains a supply of water which is directed by a pump (50) and a pipeline (51) through a manifold (7) to baths (11, 12, 13, 14, 15) by way of feed pipelines (71, 72, 73, 74, 75). Each pipeline is controlled by respective solenoid valve (61, 62, 63, 64, 65) controlled to operate simultaneously with the pump (50) by way of an electronic control unit (41) in receipt of signals relayed from sensors (21, 22, 23, 24, 25) designed to detect a drop in the level of the solutions in the baths (11, 12, 13, 14, 15). The feed outlets of the pipelines (71, 72, 73, 74 75) discharge above the level of the baths (11, 12, 13, 14, 15) so as to prevent any possibility of reflux. In the case of the pipeline (75) serving the final bath (15), water is supplied by way of a tubular element (81) with holes (85) strategically placed to generating jets directed onto at least one roller (321) of a set of paired squeeze rollers (32).

摘要： A device for washing machines to control the introduction of detergent. It is intended especially for washing machines and combined machines for the washing and drying of laundry, which have a microprocessor and a distributor with several separate compartments for the detergents and additives to be introduced into the machine tub during the laundry-washing cycle, and which are equipped as well with a selector 13 that may be set to the several compartments by means of two jointed levers 15 and 16. One such lever 15 is associated with two PTC sensors 20 and 21 containing wax which is heated when such sensors are powered. According to the invention, the device includes the connection of the PTC sensors 20 and 21 to a triac 32 powered by the machine electric circuit through a diode 34 and 35 for the purpose, so as to allow one, the other, or both PTC sensors 20 and 21 to be turned ON for every positive or negative half-wave of the electric current. This, in turn, causes the displacement of the selector 13 by means of the levers 15 and 16 to the corresponding regulatory position. A device made in this way proves to be simple and operationally reliable.
