Patent ES-372713-A1 (ES)
Title: Refractory hollow body
IPC: C21C5/46
Filed: 1969-11-20
Abstract: The invention relates to a refractory hollow body serving especially as protection for probes or lances with which the progress of metallurgical processes is tested, to a method for producing such hollow body and to a device useful in carrying out such method. The high demands placed in such protection jacket are met by providing two layers for the refractory hollow body, i.e., an inner layer of unsintered refractory mass, containing 25 - 35 percent of fine particles and 30 - 40 percent of coarser particles, and a dense, sintered outer layer of the same material, the thickness of said outer layer amounting to preferably from one-sixth to one-tenth of the wall thickness of said body. Such jacket body, whose total porosity preferably amounts to 15 - 20 percent is produced by forming a hollow cylindrical body out of a granular, refractory mass under the addition of water and consolidation by shaking, drying said body and burning said outer layer to become dense at a temperature higher than the sintering temperature, while said inner layer is cooled by a coolant.

Title: Video reproduction system for photographic and other images
IPC: H04N9/11
Filed: 1972-07-13
Abstract: An improved system for reproducing transparent photographic and other film images and opaque images on a television screen is provided in which the television picture tube upon which the image is displayed is utilized as a flying spot scanner for the image. The scanning spot from the tube is focused upon the image by a suitable lens. Light-sensitive means is positioned to receive such scanning light from the television tube which passes through or is reflected from the image and is responsive to the intensity of such light, which varies with the optical density or reflectance of the image, to produce electrical signals related thereto. These signals are amplified and returned via a suitable feed back circuit to the television unit to modulate the intensity of the screen illumination at any instantaneous spot in accordance with the signal intensity representing the corresponding spot on the image, and thereby reproduce the image upon the screen. This invention is adaptable to transparent and opaque image reproduction, still and motion picture reproduction, black-and-white and color reproduction and positive to positive and negative to positive reproduction, and may be readily employed in a home television entertainment system.

Title: Precision current-source arrangement
IPC: G05F3/26
Filed: 1975-04-21
Abstract: A precision current source arrangement with a multiple current source which supplies a number of currents which are identical in a first approximation.

Title: Apparatus for distinguishing between failures in a digital transmission network
IPC: H04J3/14
Filed: 1978-03-10
Abstract: At a channel bank, such as a D-type channel bank used in the Bell System, a steady visual alarm is exhibited if the source of a detected failure is at a location either within the channel bank or in the digital hierarchy of a digital transmission network. Unfortunately, a craftsperson is unable to distinguish between the two failure locations. To distinguish between the locations, apparatus for indicating the failure location to be in the hierarchy is situated between the hierarchy and the channel bank and, responsive to an alarm failure signal from the hierarchy, extends a predetermined cyclic code signal to the channel bank. Without modification of the channel bank and responsive to the code signal, a cyclic visual alarm in lieu of the prior art steady alarm is provided thereat.

Title: Coated absorbent structures
IPC: A61L15/60
Filed: 1978-08-07
Abstract: A method of manufacturing absorbent structures e.g. menstrual towels, nappies, surgical dressings and wiping towels, wherein a liquid- absorbing material e.g. in the form of a powder, is secured to a support e.g. a film or fibrous pad by depositing a binding agent for example poly(vinyl alcohol), particularly in the form of an aqueous solution or dispersion.

Patent ES-473471-A1 (ES)
Title: Steep gradient static characteristics electrical transformer
IPC: H01F27/28
Filed: 1978-09-19
Abstract: In an electrical transformer the primary and secondary coils 2, 3 each comprise a conductive band substantially as wide as the coil. Each primary coil is mounted on the same magnetic core column as one or more secondary coils so that the primary and secondary coils are coaxial and face one another with a gap between them. At high currents the current through the coils tends to shift to the outer (non-adjacent) edges of the conductor bands, and the gap encourages dispersed flux 6 which does not link both coils. These factors increase the slope of the output characteristic such that the short circuit current can be only twice the operating current.
Patent ES-477707-A1 (ES)
Title: Ozone generating cell.
IPC: C01B/
Filed: 1979-02-14
Abstract: Ozone generating cell. The ozone generating cell which is the object of this Invention Patent is devised n order that instead of obtaining a uniform electrostatic field gradient, as occurs in practice in known cells, several points of very high electrostatic field gradient are achieved, thanks to geometry of the electrodes, managing in this way to form intense electric discharges in these points, and, therefore, the abundant generation of ozone.  Additionally, and with the aim of aiding the freeing and the movement of the generated ozone, the electrode is not in contact with the dielectric intermediate, there being a space of some tenths of a millimetre between the electrode and the dielectric; this arrangement further increases the formation of ozone since the air situated between the electrode and the dielectric is almost entirely transformed into ozone.

Title: A Method of Rolling Angular Sections
IPC: B21B1/08
Filed: 1979-05-08
Abstract: An angular metal section is produced by rolling a rectangular elongate metal blank to form a lengthwise triangular ridge having an apical angle equal to that at which flanges of the section are to be set with respect to each other, and bending portions of the blank about this apical angle to form the flanges. The triangular ridge is formed by rolling from a rounded protuberance previously rolled on the blank. In each rolling pass, the thickness of the blank is reduced by about one third. In an additional optional pass to which the blank is subject before it is bent, the corners thereof exclusive of those bounding the surface carrying the triangular ridge are rolled to effect rounding thereof.
