Title: Method and apparatus for the production of helical seam pipe
IPC: B21C37/12
Filed: 1974-01-18
Abstract: Apparatus is provided for forming a generally cylindrical pipe having a helical welded seam from a continuous strip of metallic material, said apparatus comprising a pipe forming mechanism which includes a plurality of individually adjustable bending rollers, means for feeding the strip to the pipe forming mechanism, measurement means located upstream from the pipe forming mechanism for measuring various dimensions of the strip prior to its entry into the pipe forming mechanism, adjustable pipe guide means located downstream from the pipe forming mechanism and arranged to engage the formed pipe to adjust the angular position thereof relative to the pipe forming mechanism, and control means whereby signals derived from the measurement means may be applied to adjust the operative positions of the pipe guide means and of the bending rollers to insure that the bending operation occurs in a manner which is correlated to the dimensions of the strip being passed therethrough. Control signals derived from the measurement means are applied to control the bending operation through a control unit which, by delaying the application of the signals, correlates the bending function with the measured values of portions of the metal strip whose measurements are taken at locations upstream of the bending apparatus. The bending apparatus and the measuring apparatus each comprise a plurality of rollers arranged in rows parallel longitudinal axes. The metal strip passes obliquely of said longitudinal axes and the measurement thereof is taken along a line which is substantially parallel and equidistant from the longitudinal axes of the bending rollers.

Title: Automatic production apparatus for manufacturing of split tile
IPC: B28B15/00
Filed: 1976-02-27
Abstract: An apparatus for the continuous and automatic manufacture of both glazed and unglazed split tiles by accepting automatically produced uncured newly cut and/or stamped split tile and thereafter automatically glazing and/or hacking same for kiln firing. A first conveyor system is provided where previously cut unglazed split tiles are placed on a conveying system in a spaced-apart fashion, and moved to a transfer position. Thereafter, a whole row of the unglazed spaced-apart split tiles are transferred to a grouping table where layers for a hack are formed by a plurality of adjacent transferred rows. Each layer is subsequently transferred to a kiln car and oriented 90 DEG with respect to the just previously deposited layer so as to maintain the desired spaced relationship in the final hack. A second alternative conveying system is also provided in the preferred exemplary embodiment which moves unglazed split tiles individually through a glazing area where both sides are glazed. Thereafter, the glazed split tiles are dried and grouped in a spaced-apart fashion similar to the unglazed tiles. When a predetermined row length has been formed, such row is transferred to the same grouping table where hack layers are formed and incorporated within a hack in the same way that unglazed tile are handled.

Patent ES-448552-A1 (ES)
Title: Magnetohydrodynamic generator
IPC: H02K44/10
Filed: 1976-06-04
Abstract: The electrode (14) has an elongated first electrode element (22) which is arranged inside a second electrode element (26), forming an annular gas (24) through which gas flows. An arc is struck between said electrode elements in order to generate a plasma. The electrode (14) is arranged parallel to the direction of the magnetic flux, which results in the arc rotating about the first electrode element (22). In order to increase the power and/or to suppress erosion, the electrode material, current density and gas pressure are selected such that a cathode spot occurs, the first electrode (22) having a uniform cross-section along its operating section. This longitudinal movement is superimposed on the rotation and can be further intensified in various ways. In this way, the arc of an electrode can move much more intensively within a cavity which is located along one or more openings in the electrode. This results in the ionised gas filling the entire cavity and being forced into the generator duct, where it acts as a gas electrode. At the same time, erosion is in this way suppressed so that it is possible to operate with higher current densities than in the past. The high temperature of the electrode prevents carbon slag being deposited on the electrode opening so that a path which is electrically conductive to a large extent remains open for the load current.

Patent ES-453901-A1 (ES)
Title: Treating airborne web material
IPC: B65H20/10
Filed: 1976-12-02
Abstract: Web material is carried on air to advance the material in a fixed stable floating position through one or more decks of a treating plant, preferably a drier. The air is supplied through pairs of apertures arranged in the upper surface of blow-boxes distributed in the conveying path of the material which apertures eject the air in pairs of streams facing away from each other. To reduce deflection of the material between said pair of apertures the space between said apertures is supplied separately with a great volume of secondary air of the same static pressure as that prevailing on the upper surface of the material, which secondary air is taken along by ejector effect by the primary air streams ejected from the apertures of the blow-boxes.

Patent ES-467181-A1 (ES)
Title: Process for the continuous production of solids, in particular protein concentrates, from aqueous solutions, and apparatus for the practice of the process
IPC: H04M3/18
Filed: 1978-02-21
Abstract: A process for continuously producing dried protein concentrates, namely blood meal, from an aqueous solution of animal blood, in which the solution is atomized in superheated steam at a temperature of about 400 DEG C. The atomization of the solution is accomplished, at least in part, by a centrifugal atomizer that throws the solution radially outward in an extremely thin layer of finely divided droplets having diameters less than 100 microns. The small droplets pass into the stream of superheated steam, which causes the liquid to evaporate, and the dried blood solids to precipitate to the bottom of the collector where they are discharged by a conveyor. The superheated steam, which was cooled to about 200 DEG C. by the drying process, goes to a cyclone separator which removes any entrained solids, and is then returned to the heat exchanger, where it is again heated to about 400 DEG C. for re-use in the process.

Patent ES-475734-A1 (ES)
Title: Self-grinding valve mechanism
IPC: F16K29/00
Filed: 1978-12-05
Abstract: Improved self-grinding valve is provided with corrosion-protecting features and an improved floating coupling between the valve stem and valve disc whereby, when the valve disc is brought into contact with its seat, a selected rotation of the valve disc will produce a grinding of the seat, followed by a disengagement of the valve stem from the valve disc. When this disengagement takes place, the full torque load of the stem can be imposed upon the valve disc to obtain the desired seating of the same. The valve stem is advantageously comprised of improved telescoping and theadedly engaged sections that operate to relieve the forces used to hold the valve disc against the seat upon the initial opening of the valve whereby the amount of torque required to ultimately rotate and free the valve disc from its seat is materially reduced and seizing of the valve disc relative to its seat avoided.

Patent ES-484627-A1 (ES)
Title: Controllable inlet header partitioning
IPC: F22B37/26
Filed: 1979-10-01
Abstract: An improved reheater for a moisture separator reheater includes an inlet header, an outlet header and a plurality of heat-exchange tubes connected therebetween. The inlet header is partitioned to provide at least two separate sections. Piping and control valves are also provided to supply steam to each section of the inlet header from the reheater inlet pipe. The improved reheater includes at least one bundle of tubes communicating with the header(s) via tubesheet(s). The inlet ends of the tubes may be differentially orificed whereby in combination with a nominal flow rate to the partitions, in-tube condensate subcooling is substantially eliminated with minimal scavenging steam at design conditions. At off-design, or low power level, conditions, where fixed resistances of orifices and fixed partitions cannot accommodate changes in heat transfer demand from tube to tube, the aforementioned control valves are automatically adjusted. This invention effects a controllable inlet header partition resulting in minimal scavenging steam required to substantially eliminate condensate subcooling across the turbine load range.
