Title: Vacuum vessel for degassing molten metals
IPC: C21C7/10
Filed: 1968-04-26
Abstract: In a vacuum degassing vessel of the type having an intake pipe at its lower end for dipping into the metal to be treated, the refractory lining of the vessel merges at the top into a substantially cylindrical neck having a steel jacket, the neck being surrounded by an annular chamber having a closed top, and the vacuum connection being made through the outer wall of the chamber so that the direction of flow of the gases passing from the vessel to the vacuum connection is changed through at least 180 degrees whereby loss of heat and carryover of spray to the vacuum pipe is reduced. As shown in Fig. 1 the vessel 1 tapers to a neck 9 around which is a jacket forming an annular passage 10 from which leads the vacuum connection 4, the opening of neck 9 lying above the level of outlet 11.

Abstract: An aqueous silica sol contains 10-25% by weight of particles of silica of average diameter 2 to 5 millimicrons, has a SiO 2 /Na 2 O ratio by weight of greater than 15 and has a pH of 9-11. The sol may be prepared by treating an acidic silica sol, containing at least 5% SiO 2 and having a particle size less than 5 millimicrons, with a water soluble sodium base, e.g. hydroxide, carbonate, bicarbonate or silicate, to give a SiO 2 /Na 2 O ratio of at least 7À5 thus providing an alkaline sol, and evaporating at below 150 F., if desired at constant volume by adding either alkaline or acid sol continuously. The starting sols are preferably prepared by passing sodium silicate through ion exchange columns according to known methods (U.S.A. Specification 2,244,325, Canadian Specification 623,562 referred to), and preferably have a particle size of 1-2 millimicrons. The evaporation may be carried out under vacuum. The product sols have a conductivity greater than 3000 microohms and a storage stability of over 6 months.

Patent ES-377272-A1 (ES)
Title: Improvements in or relating to load equalising devices for two carrying cables of lifting winches
IPC: B66D1/26
Filed: 1970-03-07
Abstract: A load compensator for maintaining equal loads in the cables 21 of two winches carrying a load 22 centrally supported therebetween on a crossbar 1, comprises on the crossbar, attachment points 3, 4 for the cables and a point 5 for the load, forming an isosceles triangle whereby any tilting of the crossbar from the horizontal, causes, due to a reduced moment arm b1, a greater torque to be applied to the winch having the decreased payout. The drives for the two winches are connected together such that one winch pays out whilst the other winds in until any unequal torque between the winches is compensated for and the crossbar returns to its horizontal position. In the embodiment of Fig. 2 (not shown) the isosceles triangle is formed by a pair of chains attached at one end to each winch cable and having their remote ends attached one to each end of the crossbar. In the embodiment of Fig. 3 (not shown) each winch drum is driven from a motor through a differential gear, the two gears being interconnected to facilitate the compensation motion between the two drums. The interconnected pinions of the two differential gears may be braked so that each winch operates independently. In the embodiment of Fig. 4 (not shown), each winch is driven by an hydraulic motor, the circuits of which are interconnected through shut-off valves so that one motor acts as a pump during unequal torque conditions between the two winches, while the valves are open.

Patent ES-454996-A1 (ES)
Title: One-component developer powder and process for its preparation
IPC: G03G9/08
Filed: 1977-01-13
Abstract: Electrically conductive developer powder for developing electrostatic images by inductive attraction is provided, with avoidance of practical disadvantages of known "one-component" developer powders, by incorporating finely divided water-insoluble quaternary ammonium salt into thermoplastic resin particles forming the powder, with or without other finely divided additives such as coloring material and/or magnetically attractable material. The specific resistance of the resin particles is lowered to between 107 and 1011 ohm. cm by from 8 to 35% by weight of the quaternary ammonium salt, and can be lowered further by additions of fine conductive material such as carbon black. The resin particles remain sufficiently fusible even when they also contain enough magnetically attractable material, e.g. about 50% by weight, to render them transportable by a magnetic powder-applicator. A further important feature of the invention consists in preparing thermoplastic resin particles of suitable size with the quaternary ammonium salt already finely dispersed in them simply by coagulating an aqueous resin emulsion that contains one of the ions required for forming said salt, in a coagulant liquid containing the other of said ions. When so desired, the other additives can also be finely dispersed in these resin particles via the coagulant liquid.

Each magnetic core ring is symmetrical about the plane of symmetry of the two coils which it threads comprises an assembly of two generally arcuate parts arranged to facilitate threading of the coils on the rectilinear sides before the said core parts are joined by adhesive, the parts being separated along a plane perpendicular to the said plane of symmetry by sawing and is made of a binder-impregnated, laminar stack of magnetic sheets of at least two different widths such that two contiguous rectilinear sides of two adjacent cores threading a single coil combine to give a magnetic circuit within the coil having a right cross-section which includes steps at the changes from one thickness of sheet to another and thereby forms a closer approximation to an ellipse than would a rectangular made from magnetic sheets all of the same width.

Patent ES-479542-A1 (ES)
Title: Opto-electronic focussing error detection arrangement
IPC: G11B7/1381
Filed: 1979-04-11
Abstract: An opto-electronic focussing-error detection arrangement is described for the detection of a deviation between a radiation reflecting surface and the plane of focussing of an objective system. In the path of the beam which is reflected by the surface a beam-splitting element is disposed and behind said element two radiation-sensitive detectors are arranged which are each associated with one of the subbeams formed by the beam-splitting element. The detectors are grating-shaped detectors and are effectively divided into two detector sections by selection devices, the bounding line being adjustable. A focussing error signal is obtained which is highly independent of a positional error of the radiation-sensitive detection system relative to the beam axis.

Title: Device fabrication by plasma etching
IPC: C23F4/00
Filed: 1979-07-30
Abstract: High density fine-line integrated structure fabrication is expedited by use of plasma etching systems which assure straight vertical walls (absence of undercutting). Critical to the sytems is choice of appropriate plasma chemistry. Appropriate systems are characterized by inclusion of recombination centers, as well as active etchant species. Recombination centers which effectively terminate etchant species lifetime in the immediate vicinity of resist walls afford means for controlling etching anisotropy. Use is foreseen in large scale integrated circuitry (LSI) and is expected to be of particular interest for extremely fine design rules, i.e., in Very Large Scale Integrated circuitry.

Patent ES-8105231-A1 (ES)
Title: Process for preparing hydrogen fluoride.
IPC: B01J8/18
Filed: 1980-07-11
Abstract: A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.
