Patent ES-343224-A1 (ES)
Title: Ignition arrangement for internal combustion engines
IPC: H02K21/38
Filed: 1967-07-20
Abstract: In a generator for producing a triggering ignition impulse, the pick-up coil 31 receives flux from a pole-shoe 107 whose leading edge is so curved that the required threshold voltage is reached sooner at higher speeds, thus providing automatic spark advance. The rate of increase of width of the pole-shoe 107 presented to stator pole 55 is inversely related to the angular position so that a required rate of flux charge will depend on its angular position with respect to this pole, in addition to the rate of rotation. The shaped pole-shoe 107 is part of a cylindrical or conical surface 108, from which it is magnetically isolated but which carries the working flux not employed at any instant. This flux is generated by a permanent or electromagnet 54 and passes through shunt 111 to the surface 108, or through core 65 carrying the coil 31, depending on the position of the rotating pole 55. The polepieces may be laminated or of ferrite.

Title: Methods of Establishing a Connection on Printed Wiring
IPC: H05K3/22
Filed: 1967-08-24
Abstract: In making a soldered connection between two points on a printed wiring board by means of a substantially U-shaped wire inserted into two spaced orifices in the board, the part of the U connecting the limbs has a shape deviating from a straight line on the side remote from the limbs and after the limbs are inserted into the orifices the connecting part of the U is straightened by pressure exerted normally to the board so that the limbs are caused to diverge sufficiently to prevent the wire falling out of the orifices, the wire being subsequently soldered to the wiring board. An insulating board 1 with printed wiring 3, 5 on its lower side has orifices 7, 9 extending through the wiring and into the orifices are inserted the limbs 13 of a U-shaped wire having a kinked connecting portion 11. A stamp exerts pressure on the portion 11 to straighten it and cause the limbs to diverge so that the wire may not fall out during transport. The wire is finally secured by dip soldering. In a modification for use with more widely spaced orifices, the U connecting portion has a kink near each limb. Alternatively, the connecting portion may be shaped as a circular arc.

Patent ES-369316-A1 (ES)
Title: Self-clocked binary data detection system with noise rejection
IPC: H03K5/01
Filed: 1969-07-09
Abstract: Apparatus for indicating error in an input signal which periodically alternates in polarity and is coded to represent a train of binary digits, comprises first threshold means effective to indicate when the signal exceeds a first threshold for either polarity, second threshold means effective to indicate when the signal exceeds a second higher threshold for either polarity, and means giving an error indication if there is no output from the second threshold means to coincide with the output from the first threshold means delayed. As described, each threshold means comprises two threshold devices to detect when the threshold is exceeded positively and negatively, respectively, in the differentiated output of a reading head sensing a magnetic recording medium. The leading edges of the outputs from the threshold devices for the first (low) threshold (indicating zero crossings approximately) produce clock pulses which are used to decode the data in data detect circuitry as in Specification 1,213,688 referred to, and also produce pulses which are delayed and used to sample the inverted AND of the outputs of the positive threshold devices ORed with the inverted AND of the outputs of the negative threshold devices, any pulse produced by the sampling resetting the data detect circuitry since if the high threshold level has not been reached within the delay referred to after the low threshold level was reached it was presumably (inter-character) noise which exceeded the low threshold level. Each high threshold device, once its threshold has been exceeded, maintains its output until the signal falls below the low threshold. A single threshold device, responsive to both polarities, could be used in each of the two (high and low) threshold means. Parity is also mentioned.

Title: N-substituted cycloserine compounds, salts thereof, and processes for preparing them
IPC: A61P31/04
Filed: 1974-07-23
Abstract: Stabilized cycloserine compositions, having enhanced stability, and effective in releasing cycloserine compounds in vivo, are prepared by reacting D-4-amino-3-isoxazolidinone or its 5-methyl derivative with 2,4-pentanedione or alkyl-substituted-2,4-pentanedione to form the corresponding N-substituted-cycloserine compound in which one of the hydrogens attached to the primary amino group is replaced by 1-methyl-3-oxo-1-butenyl or an alkyl substituted-1-methyl-3-oxo-1-butenyl grouping.

Patent ES-434313-A1 (ES)
Title: High voltage protection circuit
IPC: H04N3/20
Filed: 1975-01-31
Abstract: A horizontal deflection system driven auxiliary supply for a television receiver has as a rectifying device an integrated thyristor-rectifier (ITR). When the deflection system is operating under normal conditions, the rectifier portion of the ITR provides direct operating current through conventional filter circuitry to other receiver circuits, such as the vertical deflection system, whose performance is essential to the production of a viewable display. When the horizontal deflection system generates excessive voltage which results in an undesirable increase in the picture tube anode voltage derived from the deflection system, the peak cathode voltage of the rectifier portion, and thus the peak anode voltage of the thyristor portion of the ITR, rises. When the anode of the thyristor goes sufficiently positive with respect to its cathode, the voltage drop across the thyristor exceeds its breakover voltage and the thyristor begins to conduct heavily, removing the operating current from the other receiver circuits and rendering the display unviewable.
