Abstract:
The invention concerns a method and a device for the selective extraction of the halide ions from photographic baths. According to the invention, the solutions to be treated are subjected to a first nanofiltration step 2 in diafiltration mode, then to a second nanofiltration step 3 in concentration mode. The method makes it possible to prolong the activity of the fixing or bleaching/fixing baths during the processing of photographic products.
Abstract:
The present invention concerns an electromagnetic motor of the type including a stator (4), a rotor (6) mounted for rotation relative to the stator, and a cage (2a, 2b, 2c, 2d, 2e) fixedly engaged relative to the stator, such cage including a bottom (18), a cover (22) and a body (20), the rotor being mounted for rotation in the interior of the cage, such motor being characterized in that the cage (2a, 2b, 2c, 2d, 2e) is formed from a synthetic material, while mechanical anchoring and positioning means are provided between the wall (P) of the cage body (20) and the stator (4) which leave the wall (P) free. This motor is intended for fitting out a timepiece in particular.
Abstract:
Cooked-extruded-expanded sweet snack having a porous texture, a low specific weight and a biscuit and caramel flavor. The snack includes non-fat milk solids, an oil or fat, hydrolyzed amylaceous material having a DE of from 5 to 45, and optionally, non hydrolyzed amylaceous material, a sugar or a phosphate. The snack has a diameter of 10 to 20 mm, a length of 30 to 100 mm, or both, and can be coated with a chocolate or sugar coatings.
Abstract:
The invention concerns a method and a device for extracting the halide ions from fixing or bleaching/fixing photographic solutions containing mainly thiosulfate as the fixing agent, bringing the solutions into contact with a nanofiltration module including at least two membranes of different types. The method enables the activity of the fixing or bleaching/fixing baths to be extended during the processing of photographic products.
