Patent ES-506912-A1 (ES)
Title: A carburettor and a method of carburation.
IPC: F02M11/02
Filed: 1981-11-06
Abstract: The invention provides a carburettor for an internal combustion engine, comprising an upper plate element, a lower plate element and a side wall structure which spaces the plate elements from one another to define a mixing chamber within its surround. A tangential inlet to the chamber is defined in the side wall structure while a central outlet from the chamber is provided so that fluid entering the inlet follows a vortical path en route to the outlet. In a preferred arrangement the inlet is provided with a variable throat which includes a hinged flap adapted automatically to open the throat in proportion to air flow therethrough so that velocity through the throat remains substantially constant until the flap is fully open. A fuel jet is disposed a short distance downstream from the free end of the flap so that with the flap partially open, the jet is subjected to a constant pressure differential and in order to compensate for increasing airflow, a number of jets are provided successively upstream from the first jet. Once the flap is fully open, increased air flow results in an increased pressure differential over the jets so that the air fuel ratio remains substantially constant. A feature of the invention is that during low engine speeds, for example, during starting and idling, the air velocity is sufficiently high to effect vaporisation of liquid fuel.While the carburettor is of extremely simple construction, the mixing chamber ensures a high degree of vaporisation of liquid fuel without the application of heat or dependancy upon a manifold for the internal combustion engine.

Title: Electrode set for an electrochemical generator, process for its manufacture and apparatus for carrying out said process.
IPC: H01M10/14
Filed: 1982-04-29
Abstract: A strip of an ionically permeable material (45) is wound round the lateral edges of the electrodes (30) having connecting lugs (30a), by going from the central electrode towards the peripheral electrodes, so that a sheet of this material separates the adjacent electrodes. Once the set is completed, the strip (45) is cut and soldered with the aid of a heating wire (41). The edges of the sheets of strip adjacent to the lower edges of the electrodes 30 are brought together either by a layer of thermoplastic material or by soldering all the sheets gathered one against another. In order to manufacture this electrode set two templates (27, 28) are used to position the connecting lugs for the positive, respectively negative electrodes, and these templates are rotated step by step in order to wind up the strip (45) and at the same time set down the positive and negative electrodes.

Patent ES-8305935-A1 (ES)
Title: Threshold circuit without hysteresis
IPC: B61L1/18
Filed: 1982-08-31
Abstract: This threshold circuit has two active operating states and one passive failure state. It can be used for determining the position of an alternating voltage to be evaluated, for example a track voltage in a track circuit, with respect to a reference voltage, any disturbances (for example due to component failure) being indicated by the passive state which can be distinguished from the two operating states. The invention makes use of the finding that the instantaneous frequency of an aggregate voltage produced from the addition of two voltages of different frequencies is a function of the amplitude ratio of the added voltages. Accordingly, the threshold circuit according to the invention consists of an adding circuit (AD) in which a reference voltage (U2) with a frequency (f2) which is different from the frequency (f1) of the voltage (U1) to be evaluated is added to the voltage to be evaluated and of an evaluating circuit (AWS) for detecting the instantaneous frequency (f1) of the aggregate voltage (U1) and for comparing this instantaneous frequency with a nominal value. Various variants of the evaluating circuit are the subject-matter of the subclaims.

Title: Method and device for stowing goods which can be destroyed by condensed water.
IPC: B63J2/12
Filed: 1984-05-14
Abstract: Bulk cargo which is sensitive to condensate is confined in the cargo area of a seagoing or other vessel in such a way that it comes into direct contact with the walls surrounding the cargo area and is also in contact with moisture-laden air filling the remainder of such area. In order to prevent condensation of moisture on the walls surrounding the cargo area, the temperature of the walls as well as the temperature of air in the cargo area is maintained at a value such that the moisture cannot condense on the walls. This can be achieved by heating the confined air and/or the walls and/or by reducing the moisture content of confined air and/or by a combination of such undertakings.
