Patent ES-451275-A1 (ES)
Title: Device for controlling and cutting the weft threads in looms with weft inserters
IPC: D03D47/34
Filed: 1976-08-27
Abstract: The present invention relates to means for controlling and for cutting the weft threads in looms with weft inserters. The combination of the means for controlling and for cutting the weft threads comprises a thread cutter carried by the loom framing, as well as a threader and a lowering hook carried by the sley. The thread cutter is constituted by a vertically-movable knife which co-operates with a component provided towards the rear with a weft thread retaining hook. The knife has, towards the rear, an extension for guiding the weft thread into the shed. The threader is formed by a horizontal ramp ended at its rear by an upwardly and forwardly open loop, located above the path of the entry needle, while the lowering hook may adopt, selectively, a high position above the weft thread portion connecting the threader loop to the cloth and a low position in which it presses down and holds one point of said weft thread portion below the path of the nippers of the entry needle. The invention is applicable to loom with weft insertion needles, especially for the manufacture of cloths which comprise effect or fancy threads.

Title: Means for improving ionization efficiency of high-voltage grid systems
IPC: H05F3/04
Filed: 1977-01-26
Abstract: A method and system for ionizing air passing through a metallic duct, e.g. to maintain precise electrically neutral, positive or negative atmosphere in an area, such as a textile mill, by adding charged ions to air being pumped into that area, with at least one electrical grid mounted in the duct by means of one or more insulator posts connecting the grid to a duct wall and adapted for connection to a DC high voltage source whereby buildup of conductive material such as grease or lint in a conductive path between the grid and duct wall is prevented. In one embodiment this is accomplished by providing an insulating sleeve within the duct and surrounding the grid, this sleeve by protecting against short circuits also permitting high currents to be safely used. In a second embodiment air deflectors mounted on the grid wall deflect the air in the duct away from the insulator posts, preferably with the aid of clean air injected between the air deflectors and duct wall.

Patent ES-460032-A1 (ES)
Title: Recovering magnesium from magnesium and monoooxide carbon mixture
IPC: C22B26/22
Filed: 1977-06-23
Abstract: Magnesium is recovered from a hot gaseous mixt. of Mg and Co (such as the prod. stream resulting from the redn. of MgO with carbon at >1000 degrees C), by rapidly cooling the gas in contact with a molten aluminium-magnesium alloy which simultaneously dissolves the Mg. Pref. the alloy contains >=25 wt.% esp. 30-70 wt.% Mg so that the m. pt. is as low as possible (e.g. the alloy contg. 35% Mg is fully molten at 450 degrees C). Recovery of Mg is increased if the alloy has the biggest possible surface area, which is achieved e.g. by spraying the molten alloy into the hot gas stream in the form of droplets. Process gives good recovery of Mg before it recombines with the CO to form MgO+C. The use of Mg/Al alloy is an improvement on the molten Pb or Sn previously used, since it avoids the necessity of recovering Mg from the Mg/Pb or Mg/Sn alloys, which themselves have little commercial application. The Mg is easily recovered from the Mg/Al alloy e.g. by distn.

Patent ES-463516-A1 (ES)
Title: Metal coating process
IPC: B29C65/00
Filed: 1977-10-25
Abstract: Metal substrates, such as steel sheeting or steel plates of large containers and similar structures, are coated in a continuous operation by arranging a polymer stratum that comprises a heat or melt bonding composition in contact with the metal substrate and by directing electromagnetic radiation in the radio frequency range through the polymer stratum without substantially heating the latter onto the substrate for briefly heating a surface area of the substrate to a temperature where the heat or melt bonding composition in contact with the substrate is activated to form a heat or melt bonded connection between the polymer stratum and the metal substrate. The heated surface area is moved continuously so as to bondingly coat the surface of the substrate, e.g. the fuel-receiving compartments of a tanker, with the polymer stratum. An apparatus for the coating process is disclosed and comprises an inductor loop for directing radio-frequency radiation through the polymer stratum onto the metal substrate. The inductor loop can be made to conform with the surface of the substrate that is to be coated and made resistant against corrosion.

Title: Protective relay apparatus
IPC: H02H3/46
Filed: 1979-11-07
Abstract: Protective relay apparatus for developing signals responsive to subsynchronous current oscillations in a three-phase electrical power system, and for analyzing the signals to determine when corrective action is necessary. The positive sequence component of a subsynchronous current oscillation is developed via a summing arrangement, which eliminates the need for sequence filters. The positive sequence component of a subsynchronous current oscillation is processed to determine if it is an electrical transient which would shock the mechanical system of a turbine generator, or machine, to be protected, into mechanical resonance. It is also processed to determine if it is due to a growing mechanical oscillation of a turbine generator, such as might be initiated by a change in a parameter related to the turbine generator.
