Patent ES-462924-A1 (ES)
Title: Process for the direct production of steel
IPC: C21B13/02
Filed: 1977-10-05
Abstract: Steel is obtd. directly from iron oxides by (a) converting the iron in the oxides to iron carbide and (b) converting the iron in the iron carbide to steel in a basic oxygen furnace. The heat for operation of the BOF is obtd. by oxidising the carbon of the iron carbide to carbon monoxide. Pref. the oxides are reduced and the iron converted to iron carbide in one step in a fluidised bed with a mixt. of hydrogen bearing gas and carbon contg. material, the amt. of H2 being >50 (esp. >60)% of the CO present. The iron carbide is added to the BOF and processed to steel without the addn. of external heat. Pref. the steps (a) and (b) are simultaneous and the process is auto-thermal. Steel is obtd. from iron oxide without using a blast furnace. Sources of heat for making the BOF process autothermal are obtd. in situ, i.e. sensible heat from the off-gases or the CO in the off-gases can be burned, or the CO can be reacted with the iron carbide of step (a) to raise the ratio of Fe2C to Fe3C in the charge so that sufficient carbon is available for combustion.

Title: Method of making a stator connection assembly
IPC: H02K3/04
Filed: 1978-10-13
Abstract: Dynamoelectric stator assemblies and methods of fabricating stator assemblies with new and improved winding interconnection arrangements are disclosed. In one disclosed method, windings are generated and disposed in slots of a magnetic core with end turn portions thereof being disposed adjacent a core face. At a tap insulating station, selected winding tap wires are insulated and routed to a common connecting region. The core with winding turns therein is then moved to an end turn pressing station to compress and shape the winding end turns and to condition the end turns to subsequently receive and support a connection insulator. At a connection station, a tap support and aligning means is interfitted with the core for receiving the tap wires and lead wires therein. After interconnections between respective tap wires and lead wires have been made by a connection apparatus, a connection insulator comprising a plurality of holsters is placed over connection points resulting from the interconnections thereby supporting and electrically isolating the connection points. The core and tap support and aligning means are removed from the interfitting relationship. The connection insulator is then positioned within a deformed section at the outer peripheral surface of the winding end turns established during the pressing operation. The connection insulator is retained in position by a retention means and then subsequently secured to the winding end turns by disposing lacing material about the end turns and connection insulator at a lacing station.

Title: Apparatus for winding or unwinding of a cord-shaped material
IPC: B65H19/00
Filed: 1979-03-09
Abstract: An apparatus for winding or unwinding of a cord-shaped material, e.g., of electrical cables, steel cables, or ropes, on and off a spool. The apparatus has two downwardly pointing arms, the lower ends of which each carry a sleeve for receiving the spool. Since the exchange of particularly heavy weight spools previously was time consuming and physically very strenuous, whereby in addition a great danger of injury exists for service personnel, for the elimination of these disadvantages the invention provides that about a horizontal axis at least one of the sleeve arms is able to be swung up out to over the space assumed by a spool which has been set on the floor, and the apparatus is open on the side of the swingeable-up sleeve arm to an extent facilitating a relative movement of the spool and the apparatus.
Patent ES-481542-A1 (ES)
Title: Device for moulding foamed plastic articles.
IPC: B29C39/00
Filed: 1979-06-13
Abstract: In the course of this method, an amount of expansible mixture is poured into a mould, after which the mould is obturated by means of a plug. A vacuum is created in the chamber of the mould by way of the plug so as to cause the foaming of the mixture. The vacuum is maintained for a period after the foamable mixture has filled the whole of the volume of the mould. At the end of the polymerization of the foamable mixture, the vacuum may be re-applied in the mould, preferably for several cycles, so as to cause the cells of the foam obtained to burst.

Patent ES-8100723-A1 (ES)
Title: Jet impingement solar collector
IPC: F24S10/80
Filed: 1979-10-24
Abstract: A solar collector is described in which air passed through the collector is heated by exchanging heat with a plate which absorbs solar energy. The collector includes a lightweight frame of rectangular cross-section having an inlet and outlet for passage of air, with the top of the frame sealed by a light-transmissive cover such as a sheet of glass. Also included in the collector are an absorber plate mounted in the frame below the cover, and a jet plate spaced a prescribed distance below the absorber plate. One or both of the plates is corrugated, and holes are provided in the jet plate at locations where the gap between plates is a minimum so that during operation of the collector, jets of air are directed through the holes and impinge on the lower surface of the absorber plate to produce efficient heat transfer, while channels defined by the corrugations facilitate flow of the spent jets to the collector outlet with minimal interruption of downstream jets. The disclosed collector provides cost effective solar energy collection since it achieves high air heating efficiencies, is inexpensive to construct, easy to handle and install, long-lived, and is readily adaptable to multi-stage assemblies.

Abstract: A process for removing arsenic from aqueous mediums by adding, in the presence of phosphorus, sufficient calcium hydroxide to adjust the aqueous medium to a pH of from about 7.0 to 11.5, whereby precipitates of both arsenic and phosphorus are formed and are subsequently separated from the aqueous medium. As a secondary treatment, calcium salts of arsenic and phosphorus in oxidation states lower than +5, and thus dissolved in the aqueous medium are oxidized, as by the addition of chlorine or hypochloride to such medium, and thereby converted to more insoluble forms which are separated from the aqueous medium as precipitates.

Title: Data processing system
IPC: G06F15/16
Filed: 1980-03-11
Abstract: In a data processing system central processor units (10 and 10A), input/ output units (12), memory units (11) and secondary storage units (24, 25, and 26, 27) are interconnected by a bus (14). When one of the units, for example the processor unit (10), is to transfer information to a second unit, for example the controller (20) of the memory units (11) over the bus (14), the first unit, to prevent other units gaining access to the bus, generates a first signal onto a line in the bus (14) for a predetermined number of clock pulses, e.g. one cycle conflicting requests for bus access being resolved by priority arrangements. The second unit then takes over generation of the first signal on the bus line after the predetermined number of clock pulses up to the end of the transfer.
