Patent ES-362530-A1 (ES)
Title: Gain controlled amplifier
IPC: H03G3/30
Filed: 1969-01-15
Abstract: A gain-controllable amplifier comprises a transistor with its collector-emitter path connected to output terminals and having variable insertion loss means connected for coupling input signals across the series connection of the base-emitter junction and a variable impedance a gain control signal is applied to control the variation of the variable insertion loss means and also the variable impedance, in such a manner that at first the variable insertion loss means is not varied while the variable impedance means progressively degenerates the signal gain of the transistor, and for further reduction of gain the attenuation provided by the variable loss means is increased. Emitterfollower 28 is coupled to the base of transistor 12 in cascode pair 12, 14 via an attenuator comprising the collector to emitter path of transistor 26. Transistor 12 is emitter-coupled to a further transistor 36, the common emitter load comprising resistor 42 shunted by diode 40. An automatic gain control voltage is applied to the base-of transistor 30, the collector of which, together with base of transistor 28 is biased to the fixed potential 3V be , and the emitter potential of which controls the base potentials of transistors 26, 36 via resistor 34 and diode 38 respectively. At maximum gain, transistor 30 is biased to be saturated, its emitter current then causing transistor 26 to be conductive and of low impedance and also transistor 36 to conduct, rendering diode 40 conductive whereby it is of low impedance, so that negative feedback in the amplifier 12, 14 is at a minimum. As transistor 30 is biased back, transistor 26 at first remains conductive, while the reduction in current caused in transistor 36 causes diode 40 to be rapidly cut-off, whereby negative feedback in amplifier 12, 14 increases until it is controlled by the emitter circuit impedance of transistor 36. Beyond this point, transistor 26 is increasingly biased back and provides additional attenuation.

Patent ES-431140-A1 (ES)
Title: Current output frequency and phase comparator
IPC: H03L7/091
Filed: 1974-10-18
Abstract: A signal combining circuit supplied current to both amplifiers of a first differential amplifier and to an error voltage storage circuit. The first differential amplifier is controlled by the difference between a first input waveform and its average value or a reference value and this difference results in charging and discharging of the error voltage storage circuit to raise and lower its voltage respectively. A second differential amplifier alternately keys the first differential amplifier into conduction in response to a second input waveform to update the error voltage and subtracts the output current from the signal combining circuit to shut off the first differential amplifier and hold the error voltage in a high impedance circuit until the next updating period.
Patent ES-435994-A1 (ES)
Title: Hybrid soybean production
IPC: A01H5/10
Filed: 1975-03-25
Abstract: Heretofore there has been an unfilled need for an efficient process for the production of seed capable of growing F1 hybrid soybean plants. The first commercially practicable solution to this need is described. A substantially uniform first population of atypical soybean plants having exposed floral stigmas and the propensity to yield seed of a small size is grown adjacent to a substantially uniform second population of soybean plants having the propensity to yield seed of a larger size. The soybean plants of the first population are capable of undergoing cross-pollination with the aid of pollen carrying insects as well as self-pollination. Following cross- and self-pollination and seed formation seed selectively is recovered from the plants of the first population, and is segregated on the basis of seed size with the relatively larger seed resulting from the cross-pollination being capable of growing F1 hybrid soybean plants. In a preferred embodiment of the process the plants of the first population additionally exhibit a characteristic wherein the dehiscence of anther tissue to discharge pollen is delayed at least until the florets open, and/or produce less than the normal quantity of viable pollen commonly observed in soybean plants thereby tending to enhance the relative proportion of cross-pollination occurring in the first population. The relative purity of the resulting F1 hybrid seed following separation on the basis of seed size can be confirmed by providing a recessive genetic gene marker (e.g. a particular flower color) in the first population of plants and a corresponding dominant gene marker in the second population plants. When cross-pollination occurs, the recessive marker which is perpetuated upon self-pollination is no longer observable. If desired the seed capable of growing F1 hybrid plants may be used as foundation seed for the production of F2 planting seed which continues to exhibit an appreciable degree of enhanced vigor and seed yield compared to standard later generation soybean varieties, following the self-pollination of same.

Title: Method and apparatus for controlling the amount of fuel metered into an internal combustion engine
IPC: F02D41/26
Filed: 1977-04-04
Abstract: Method and apparatus for controlling the amount of fuel metered to an internal combustion engine through electrically-controllable valve means, such as electromagnetic fuel injectors. The valve means delivers the fuel to the engine in a quantity that varies as a function of an electrical signal representing the mathematical product obtained by multiplying a binary number electrical signal by an electrical signal representing a condition of the engine. The binary number electrical signal is a coefficient of the engine-condition electrical signal and is calculated, by a programmed digital computer, from a function or functions describing a desired relationship between the coefficent value and various electrical signals representing variable conditions of engine operation. The binary number electrical signal is repetitively recalculated by the digital computer. However, the product electrical signal is generated continuously or at a rate greater than the rate at which the repetitive calculation of the binary number electrical signal takes place. Consequently, with respect to variations in the engine-condition electrical signal, the product electrical signal used to determine the amount of fuel metered to the engine is up-dated continuously or at a rate greater than that at which the digital computer updates the binary number electrical signal.

Patent ES-475458-A1 (ES)
Title: Crimped hollow fibers for fluid separations, bundles containing the hollow fibers, and apparatus and process for separating fluids
IPC: D02G3/02
Filed: 1978-11-28
Abstract: Hollow, semi-permeable fibers which are intended for use in fluid separations have crimps with amplitudes up to 50% of the external diameter of the fiber and an average crimp period of less than 5 cms. The fibers are sufficiently rigid to retain its crimp form during fluid separation. Preferred fibers have an outside diameter of 150-800 microns, a wall thickness of 50-200 microns and a crimp amplitude of 15-250 microns. The tensile modulus is at least 40 kg/mm<2>. The relatively low amplitude crimps enable good fluid dispersion through a bundle comprising substantially parallelly-oriented hollow fibers such that shell-side (i.e., the exterior sides of the hollow fibers) feed of the fluid mixture to be treated can be attractive, even when the flow of the feed is predominantly axial to the hollow fibers. Shell-side feed of the fluid mixture to be treated is often particularly advantageous since the fluid mixture can frequently be recovered from the fluid separation with a relatively low pressure drop.

Title: Methods for the continuous conversion of magnetic values into electrical values.
IPC: H01F/
Filed: 1980-09-05
Abstract: The magnetization of the core of an inductance diminishes its reactance. The magnetization of the core, common to two or more inductive circuits, modifies the characteristics of a local oscillation, the mutual induction and the transference of energy. The phenomenon is governed by the composition, the form and the dimensions of the core, by the value and the construction characteristics of the inductive and oscillatory circuits and by the reciprocal position of the components with respect to the core. This method for the continuous conversion of magnetic values into electrical values is based on the determined premagnetization of various core-types of one or various inductive and oscillatory circuits, to obtain significant electrical changes in these circuits, by little alterations of the initial premagnetization.
