Patent ES-8404410-A1 (ES)
Title: Process for preparing 2-keto-L-gulonic acid.
IPC: C12R1/18
Filed: 1983-03-04
Abstract: 2-keto-L-gulonic acid is prepared directly from D-glucose by microbial conversion utilizing mixed culturing on a medium containing D-glucose, employing two types of microorganisms: the first, a 2,5-diketo-D-gluconic acid producing microorganism which belongs to the genus Erwinia and the second, a 2-keto-L-gulonic acid producing microorganism which belongs to the genus Brevibacterium or Corynebacterium. The incubation of the microorganisms in a medium containing D-glucose is used in the disclosed process. By-production of 2-keto-D-gluconic acid, the undesired isomer of the intended product, is effectively prevented by employing the mixed culturing because of the co-existence of the both microorganisms in the medium during at least part of the entire cultivation. Namely, 2-keto-D-gluconic acid produced by the second microorganism is utilized by the first microorganism to produce 2,5-diketo-D-gluconic acid which is subsequently converted into 2-keto-L-gulonic acid by the second microorganism.

Patent ES-8503417-A1 (ES)
Title: Slack adjuster for a disc brake.
IPC: F16D65/56
Filed: 1984-04-11
Abstract: A slack adjuster is for a disc brake of the type which includes a disc mounted for rotation about an axle and a caliper brake having a housing mounted on the axle in alignment with a friction surface of the disc. A braking piston is mounted in the housing for axial movement toward and away from the friction surface of the disc. Brake actuation produces rotation of a powershaft mounted in the housing which will in turn produce a corresponding axial movement of the braking piston through a non-rotating powershaft nut. An adjusting sleeve between the piston and the powershaft nut is threadably coupled to the piston and capable of rotation in a first direction relative thereto to adjust the axial position of the piston toward the disc. A clearance sensing ring is mounted about the adjusting sleeve for axial movement therewith and has an angled groove in its outer surface for receipt therein of a cam pin which is secured to the housing. The angled groove has opposite parallel walls with an axial distance therebetween equal to an axial thickness of the pin plus a predetermined maximum distance corresponding to the desired running clearance for the piston. Camming between the groove and the pin will cause rotation of the clearance sensing ring in the first direction when the axial movement of the adjusting sleeve toward the disc exceeds the predetermined maximum distance and in an opposite direction when the axial movement of the adjusting sleeve away from the disc exceeds the predetermined maximum distance. A clutch element is mounted on the adjusting sleeve with the clearance sensing ring mounted thereon to produce corresponding rotation of the adjusting sleeve in the first direction until the piston contacts the friction surface of the disc and to prevent corresponding rotation of the adjusting sleeve in the second direction.

It is preferable to stop the articles in their free fall by one (or more) front stop(s) and if appropriate a rear stop. The corresponding device permits, for example, the stacking of light-alloy discs without mutual excess relative friction at a rate ranging up to 5 articles per second.
Patent ES-8607759-A1 (ES)
Title: Process and apparatus for keeping a predetermined pulp level in a flotation cell
IPC: B03B13/00
Filed: 1985-05-09
Abstract: Known pulp level controls in flotation cells for froth flotation of fine-grain substances, in particular coal, are carried out with great instrumental complexity and high costs, where variations in pulp feed must have equally large variations in pulp withdrawal or froth withdrawal as a consequence in order to prevent overflow of the pulp into the froth outlet. According to the invention, maintaining a predetermined pulp level in a flotation cell is simplified and improved in terms of engineering by withdrawing the floated pulp, depending on the pulp feed rate into the flotation cell, in part beneath the foam discharge and in part at the bottom out of the flotation cell by separate outlet pipes for the floated pulp.
