Patent ES-381813-A1 (ES)
Title: Ignition arrangements for internal combustion engines
IPC: F02P1/08
Filed: 1970-07-15
Abstract: An arrangement for providing ignition pulses for an internal combustion engine while at the same time inhibiting ignition pulses from being applied when said engine is operated in the improper direction. Ignition pulses are produced through an ignition coil which has its primary winding connected to a capacitor charged through a magneto generator. Discharging of the capacitor is controlled through a thyristor which, in turn, is fired through the application of pulses derived from pulse emitters. The thyristor is switched to the conducting state, during improper operating direction of the engine, by the voltage pulse which causes charging of the capacitor when the thyristor is in the nonconducting state.

Title: Device for dispensing fluids
IPC: A61M15/00
Filed: 1972-07-17
Abstract: A device for dispensing fluid from an aerosol container of the kind which meters discrete doses, operable to dispense the dose when suction is applied. The preferred form of the device has a recess to hold the aerosol with the outlet of the aerosol sealingly secured in a cavity, and a resilient element to seal the outlet from the cavity, which opens into an air duct. The resilient element is held against the cavity outlet by a spring-loaded pivoted arm, and a vane on the arm is located in the air duct, so that suction applied at the outlet of the duct will cause the vane to pivot the arm and release the element. In use, the aerosol is operated to meter a dose, which is held partly in the aerosol outlet and partly in the cavity until suction applied at the outlet of the duct causes the cavity to be opened and the dose dispensed into the duct.

Title: Refrigerated cabinet construction
IPC: F25D23/06
Filed: 1974-06-27
Abstract: A disclosed refrigeration cabinet has an integrated construction of sheet material and insulating foam which substantially eliminates the need for mechanical fasteners and welding, minimizes assembly operations, and permits the use of prefinished sheet panels.

Patent ES-437875-A1 (ES)
Title: Reducing the contents of heavy metals in solution
IPC: C02F1/52
Filed: 1975-05-07
Abstract: For the purification of effluents containing heavy metal compounds, these waters are contacted with an element selected from those more electropositive than hydrogen. The reduction reaction must be carried out at a pH less than or equal to 3. The water to be treated is caused to flow through one or more columns filled with the more electropositive element in the form of granules, beads, strips, shavings or any form compatible with the dimensions of said column. If, for example, the waters to be treated contain chromates, the element used is iron. In this case, the exit pH from the reduction system is kept below the value corresponding to that at which the iron is precipitated as hydroxide. In this way, purification of the waters is achieved with a reduced consumption of more electropositive elements, in this example, iron.

Filed: 1976-07-24
Abstract: The stage section comprises a pair of planar stage surface members hinged together for movement between a compact folded position, and an operative position. Pairs of main support legs are pivotally attached to each stage surface member so as to remain substantially vertical to support the stage in both the operative and folded positions. Castor wheel assemblies are mounted near the bottoms of the support legs, and a manually actuated mechanism is provided for controlling the retraction or extension of the wheels into ground engaging position, independently of the unfolding of the stage, so that the stage can first be unfolded, then moved precisely into the desired position before retracting the wheels to transfer the stage load to the support legs. A safety locking mechanism for stabilizing the stage in its unfolded, operative position has a lever which projects alongside the edge of the stage in its unlocked position, so as to prevent inadvertently juxtaposing a plurality of stage sections to form a large stage surface, while the sections are in their unlocked position. Telescoping support legs, and adjustable cross braces cooperate to provide great stability of the structure even at very high positions of the stage.

Patent ES-474463-A1 (ES)
Title: Radiation detection device
IPC: A61B6/03
Filed: 1978-10-26
Abstract: A radiation detection device comprising a housing which comprises an entrance window and in which at least one ionization chamber detector is arranged. The detector comprises a flat high-voltage electrode which is directed transversely transverse the entrance window and a flat collector electrode which is arranged to be at least substantially parallel to the high-voltage electrode. The end faces of these electrodes which face the entrance window are in electrical contact with a flat auxiliary electrode which extends parallel to the entrance window. As a result, a small direct current flows in a direction transverse to the other electrodes during operation, because the auxiliary electrode has a low electrical conductivity. Consequently, the electrical field in the ionization chamber detector is very homogeneous, with the result that the measuring speed can be optimized.
