Patent ES-518440-A0 (ES)
IPC: F04D27/00
Filed: 1982-12-22
Abstract: The invention relates to a method of improving the part-load behavior of a turbo machine operating with a rotor 13 having fixed vanes 14. Such method uses the feature of applying auxiliary fluid injection nozzles 18 near the inlet 11 of the rotor for adding a small amount of fluid to the main fluid flow. The additional amount of fluid is projected in direction such that a substantial velocity component of the movement of this additional fluid is directed tangentially with respect to the rotation of the rotor 13.

Abstract: Hydrocarbon streams such as naphtha are treated by the oxidation of mercaptans into disulfide compounds which remain in the hydrocarbon stream. The conversion is effected during passage of the hydrocarbon and an aqueous stream downward through a cylindrical mass of liquid-liquid contact material (6). The liquids then flow through a cylindrical screen (8) into an annular separation zone which surrounds a lower part of the contact material. After decantation in the separation zone, the aqueous material, which preferably contains the oxidation catalyst, is recycled.

IPC: B60T8/18
Filed: 1985-02-12
Abstract: o A brake control system for a multiple unit train of mixed motor cars and trailer cars - of the type usually to be found operating as metro or mass transit trains - and in which the motor cars have dynamic brakes operation of which is blended with, but given preference over, the friction brakes of all units. A brake demand signal calling for a given level of train retardation is weighted on each vehicle, according to the load of the vehicle, and the level of dynamic braking effort invoked on each motor car is limited in accordance with a maximum adhesion level calculated in proportion to the measured load of that car. In a modified arrangement the adhesion level is calculated in accordance with the load of the lightest loaded motor car. Signals representing the amount of dynamic brake effort achieved by each motor car is supplied to a trailer car and subtracted from the load weighted braking effort for the trailer car and the result used to actuate the friction brakes of the trailer.

IPC: G11B5/58
Filed: 1983-05-06
Abstract: A misposition correction system for correcting misposition errors due to spindle runout and other slowly varying errors in a servo positioning system of a magnetic disk storage device. The system includes means for dynamically measuring misposition error with respect to a data track centerline using an anti-aliasing analog filter, means for digitizing the measured analog signal and for removing selected harmonics of the fundamental-frequency of the resulting cyclic error signal, means for transforming the digitized error signal by a matched digital filter whose transfer function contains independently adjustable DC gain, fundamental-frequency gain, and phase lead components thereby to generate a misposition error correction signal that matches the electrical and mechanical response characteristics of the servo system. Further, the system include means to iteratively refine the correction signal by re-applying it to the servo controller when measuring misposition errors with respect to the data track centerline. The system stores separate misposition correction signals for each transducer on the disk so that one of several correction signals can be selected depending on which transducer in the device is selected. The system further includes means for generating a bias force correction signal to correct for non-linear position errors resulting from variations in bias forces acting on the transducer carriage over its range of radial displacement.

Abstract: An axially elongated rock drill includes an axially extending shank and a drill head on one end of the shank. The drill head has a drill face extending transversely of the axial direction of the rock drill. A hard metal cutting plate and hard metal cutting pins are set in the drill face. The cutting pins reduce the wear on the cutting plate and afford better support of the drill. The cutting pins are arranged, in part, parallel to the axis of the drill, and, in part, inclined to the drill axis. The cutting plate has a cutting edge which generates a cutting plane as the drill is rotated with the ends of the cutting pins projecting from the drill face being located in the generated cutting plane.

Abstract: S-(-)-atenolol (4-(2-hydroxy-3-isopropylaminopropoxy)phenyl acetamide) is obtained by a process including the step of stereo-specific epoxidation by an ester of 4-allyloxyphenylacetic acid using a micro-organism capable of stereo-selective epoxidation, e.g. Pseudomonas oleovorans, to produce the corresponding ester of 4-(2,3-epoxypropoxy)phenylacetic acid which is predominantly in S configuration. Pseudomonas oleovorans ATCC 29347 produces at least about 90% of the epoxypropoxy compound in S configuration. The resulting epoxypropoxy compound can be converted into atenolol, maintaining the high proportion of S configuration, by reacting the epoxypropoxy compound with isopropylamine and converting the ester group to an amide group by reaction with ammonia.
