Patent ES-8202296-A1 (ES)
Title: Electronic track current switching relay system
IPC: B61L1/18
Filed: 1980-10-16
Abstract: An electronic system which emulates the operation of a polar relay for applying coded pulses to railway tracks has separate signaling circuits having signaling devices responsive to a separate inputs which provide operating power to the circuits. The circuits are interlocked by connecting the inputs to the signaling devices in inverse relationship. One input excludes the other. The signaling devices may be light emitting isolators with switching transistors which control the application of current pulses through the rails of the track while isolating the track battery which supplies the current for these pulses from the local battery which provides the inputs to the signaling circuits. The signaling circuits establish current paths through the light emitting signaling devices at predetermined times after the inputs are applied to emulate the pickup and drop away time of the polar relay. The switching circuits use complementary symmetry power transistors which provide fail safe operation in the signaling system in the event of a short-circuit failure mode throughout. Dual sets of bridge circuits and transient absorbers protect against voltage surges from the track such as may be due to lightning. Operating windings for local circuit relays are connected in series with the power transistors and operate only in response to actual signaling conditions. The signaling circuits and the switching circuits are arranged so that operating current for a circuit which functions to produce track current pulses of one polarity is available only if the circuit which would provide track current pulses of the opposite polarity is inoperative so as to guard against unsafe signaling conditions.

Patent ES-8300224-A1 (ES)
Title: Raster distortion corrected deflection circuit
IPC: H04N3/233
Filed: 1981-06-30
Abstract: An inverter applies a square-wave exciting voltage of horizontal deflection frequency to the primary winding of a ferroresonant power transformer. A square-wave alternating polarity output voltage developed across a secondary winding of the ferroresonant transformer is half-wave rectified and applied to an input choke of a horizontal deflection circuit. The input choke is coupled to the series arrangement of a horizontal deflection winding and a trace capacitor. A pincushion correction circuit switching transistor applies a DC voltage to the input choke at a controlled instant within the nonconduction interval of the half-wave rectified output voltage. The peak-to-peak horizontal scanning current is a function of the average voltage developed across the trace capacitor. This average voltage equals the average value of the voltage applied to the input choke. By varying at a vertical rate in a parabolic manner the controlled instant at which the switching transistor applies the DC voltage to the input choke, the peak-to-peak horizontal scanning current is modulated at a vertical rate in a parabolic manner to provide side pincushion correction.

Title: Laminated core of transformer
IPC: H01F3/02
Filed: 1982-01-28
Abstract: In the conventional stacking method of the laminated core of a transformer, grain-oriented silicon steel sheet pieces of an identical grade or the identical magnetic properties are used as legs and yokes of the core. In a highly oriented silicon steel sheet having a high B8 value due to excellent magnetic properties in the rolling direction of the sheet, the excellent magnetic properties cannot be fully utilized for the watt loss reduction in the conventional stacking method. In a laminated core of the present invention, the transformer core comprises a grain-oriented silicon steel sheet having a higher orientation used for a leg(s) and a grain-oriented silicon steel sheet having a lower orientation used for a yoke(s). The former steel has the B8 value of generally 1.88 Tesla or higher and preferably 1.89 Tesla or higher. The latter steel has the B8 value of generally 1.86 Tesla or lower. A low watt loss, particularly at a low or medium magnetic flux density, can be achieved by the present invention, while decreasing the cost of the transformer.
