Title: Method and apparatus for separating water-hydrocarbon mixtures
IPC: B01D17/02
Filed: 1968-02-03
Abstract: "Cleaning" water containing hydrocarbons and sediment, e.g. from the tanks of an oiltanker, is admitted at 9, de-gassed at 8, and led to the bottom of a separator 1 at 5. The mixture passes upwards between bottom 3 and cone 11 and is discharged radially inwards at 14 to a first separating stage 15. From here, hydrocarbons rise at 16 to be discharged at 42, 43 while water flows upwards through a funnel 20 to the space between cones 19 and 22. From here, the mixture is again discharged radially inwards, this time at 25 into second stage 26. Hydrocarbons rising at 27 are again discharged at 43. After a third separation stage, residual hydrocarbons are discharged at 54 and water at 44. Sediment may be collected in space 10 by opening valves 11a 22, 32a simultaneously (47, 46), and discharged therefrom by opening valve 4. In a modification, the incoming mixture flows horizontally in a half-annular path at the top of the apparatus, where air is released and where partial gravitational separation occurs. The liquid parts of the mixture pass over a lower weir at which sediments are arrested and periodically discharged, and then separated hydrocarbons pass over an upper weir on their way to the final hydrocarbons discharge. The remaining mixture then flows downwards to a bottom entry to the apparatus as before. Angled vanes are provided at each of the locations corresponding to the diffusers 14, 25 and 35 and between diffuser 35 and the interior, three concentric cylinders with vertical baffled slots (forming a kind of filter) are provided to assist separation. In a further modification, the angled vanes just referred to are replaced by upwardly and inwardly-directed vanes radial with respect to the apparatus these vanes are extended downwards nearly to the funnels 20, 31 in each case to form numerous radial partitions between the pairs of cones 19, 22 and 30, 33, respectively.

Title: Method of providing an anti-implosion clamping band around the envelope of a picture tube
IPC: H01J29/87
Filed: 1969-04-11
Abstract: A steel anti-implosion clamping band 7 which is initially smaller than the cathode-ray tube faceplate 1 it is to surround, is applied to the tube by first coating the tube with thermal insulation, then heating the band 7 so that it will slide into position, preferably with one edge against a mould match line 17, and then allowing the band to cool and shrink into place. The temperature to which the band is heated may be 450 C. and should be such that on shrinkage the band is tensioned to its yield point in spite of the tolerances in dimensions of the band and of the faceplate. When the band is entirely on the cone side of the mould match line a tensile force of 500-700 Kgm is required, and this may be obtained by reinforcing the band with a separate band 8, or by folding over the edge of the band either outwards or inwards (Figs. 3 and 4, not shown) possibly with a reinforcing band arranged in the fold (Figs. 5 and 6, not shown). The material 6 may be polyvinyl acetate or epoxy resin, and the space at the rear of the band may be filled with adhesive 18 such as epoxy resin, urea or sulphur, which should not extend over the seal 3 between the cone 2 and the faceplate 1.

Patent ES-385016-A1 (ES)
Title: Apparatus for the noise-compensated measurement of high d.c. currents
IPC: G01R1/20
Filed: 1970-10-29
Abstract: The invention relates to an apparatus for measuring current intensity in a direct current circuit through which much current flows, e.g., electrolysis of sodium chloride, by measuring the voltage drop in a conductor included in the high current circuit. Noise would normally be generated in the measuring circuit by changes in the magnetic field surrounding the conductor as a result of changes in current flow in the conductor and this would cause errors in current measurement corresponding to said changes. Accordingly, a multi-turn coil is included in the measuring circuit and it is positioned in such a way that the voltage induced into the coil by changes of the magnetic field compensates the noise voltage induced into the other part of the measuring circuit. The exact magnitude of the voltage induced into the coil is controlled by a variable resistor so that it can be equated to said noise voltage.

Patent ES-400662-A1 (ES)
Title: Method of manufacturing a component for use in a roller clutch assembly
IPC: B23P15/00
Filed: 1972-02-28
Abstract: A component for a roller clutch assembly includes a sleeve having a head part and a shank part, and the component is produced by first cropping a steel bar to produce a slug having a length to diameter ratio of not less than 0.75. The slug is then deformed into a substantially cylindrical billet having a diameter substantially equal to the diameter of the head part of the finished component. After heat treatment of the billet to remove work hardening, an axially extending, centrally disposed bore is formed in the billet and the billet is positioned in a die. Within the die, a punch is used to perform a first impact extrusion process on the billet so that metal flows in the direction of movement of the punch and produces a preform defining the shank part of the sleeve and having a head portion which tapers inwardly to towards said shank part. The preform is then heat treated to remove work hardening and a further punch is then used to perform a second impact extrusion process on the preform. In the second extrusion process, metal flows in the opposite direction to the direction of movement of the further punch and effects shaping of the preform so that the included angle of the tapering head portion of the preform is increased to produce the head part of the sleeve and thereby, the finished component.

Patent ES-456385-A1 (ES)
Title: Method for gaseous reduction of metal ores
IPC: C22B5/12
Filed: 1977-02-28
Abstract: An improvement in a method for the batchwise gaseous reduction of iron ore to sponge iron in a multiple unit reactor system including a cooling reactor and a series of reduction reactors. Reduction is effected with a gas composed largely of carbon monoxide and hydrogen generated by reforming a mixture of steam and natural gas or other gaseous hydrocarbons at an elevated temperature. The reducing gas pressure drop through the system is decreased by using an out-of-line cooling reactor and cooling gas loop, thereby making it feasible to use three or more reduction reactors in series and thus enhance the efficiency of utilization of the reducing gas.Also the use of an out-of-line cooling reactor permits independent control of both the gas flow rate and gas composition in the cooling loop.
