Patent ES-426704-A1 (ES)
Title: Braking circuit for alternating current induction motor
IPC: H02P3/18
Filed: 1974-05-28
Abstract: A braking circuit is provided for squirrel-cage induction motors supplied from a variable frequency inverter to obtain increased braking torque when the motor is used for dynamic or regenerative braking, as in traction drives. This is accomplished by connecting resistive means in series relation with the motor windings to cause a voltage rise across the windings when the motor is driven as a generator. Control means are also provided for removing the resistive means from the circuit during motoring operation, and for controlling the effective value of resistance during braking to control the braking torque.
Patent ES-438589-A1 (ES)
Title: Manufacture of lower aromatic compounds
IPC: C07C67/00
Filed: 1975-06-16
Abstract: Certain acidic heterogeneous catalysts produce large yields of benzene, toluene and xylene from alkyl aromatics of at least nine carbon atoms by a mechanism different from the classical disproportionation reaction characteristic of acid catalysts. These catalysts are characterized by a zeolite of the ZSM-5 type or zeolite ZSM-12 or zeolite ZSM-21. The reaction has the unique function of providing aliphatic by-products of higher molecular weight than is to be expected by splitting side chains from benzene rings. Typically, aromatic mixtures so derived from such charge stocks have unusually low content of ethyl benzene, thus greatly simplifying separation of xylene isomers.

Title: Air-conditioning duct in particulat for mine and tunnel workings
IPC: F16L31/00
Filed: 1977-05-31
Abstract: Each duct (1, 2) consists of a flexible plastic tube which has identical end rings (4, 7) at its two ends. The end rings (4, 7), fitted into each other, of the adjacent ducts (1, 2) form a first coupling which absorbs axial forces. The second coupling consists of a sleeve (8) which surrounds the first coupling consisting of end rings (4, 7) from the outside. Each sleeve (8) is split into two halves (9, 10). A fastening (24) serves to join together the facing edges (19, 20) of the halves (9, 10). The fastening (24), which advantageously consists of lacing cord, is pulled through recesses (21, 22) in each sleeve half (9, 10). Separation of the ducts (1, 2) from one another is avoided by the second coupling even at maximum pressures. In addition, the sealing capacity of the tube connection in the couplings is improved.

Abstract: In a process and an apparatus for controlling oxides of nitrogen in exhaust gases from combustion equipment by decomposing the oxides, in the presence of oxygen, with ammonia blown into the equipment and associated ducting at temperatures within the range from 700 DEG to 1300 DEG C., a catalyst assembly is arranged, with the catalytic surfaces of the component units substantially in parallel to the direction of exhaust gas flow, in a region where the temperature of the gas after the decomposing treatment is between 300 DEG and 500 DEG C., and the gas after the decomposing treatment is caused to pass through the catalyst assembly to decompose residual nitrogen oxides and ammonia in the gas to innocuous substances. An additional supply of ammonia, in an amount from 0.5 to 1.5 times equivalent (in molar ratio) to the amount of nitrogen oxides in moles in the gas is introduced into the space immediately upstream of the catalyst assembly, thereby to accelerate the decomposition of the oxides in the gas to make it harmless.

Title: Speed control system for combine harvesters
IPC: H02P23/00
Filed: 1979-05-12
Abstract: The speed of a harvester is controlled by electrical signals derived from the functioning of the harvester. A first signal is obtained by sensing the density of some or all of the harvester output and a second signal is obtained from the drive for the harvesting apparatus. The first and second signals are compared to produce a difference signal with which the forward speed of the harvester is controlled so as to reduce the difference signal to a minimum. An indication of whether the actual speed of the harvester is correct or too slow or too fast at any instant, for a given crop loss is provided by three differently coloured lamps. The output from the straw shaker, the output from the sieve due to the air blast, and the output from the main sieve are sensed to provide output signals which are either treated separately or jointly to provide three individual signals or a composite signal relating to output density.
