Patent ES-292129-A1 (ES)
Title: Electrostatic frosting
IPC: G03G16/00
Filed: 1963-10-02
Abstract: A xerographic plate (produced as described in Division G2-G3) with an image pattern having a frosted appearance with a random pattern of ridges and valleys is covered with ink made up of equal parts of " Strip " (Registered Trade Mark) Fountain Pen Ink and isopropanol and then pressed against a piece of paper to produce a visible copy of the frosted image. Ink patterns can also be uniformly or selectively transferred by electrostatic forces. Alternatively, an ink prepared by adding colloidal graphite to a gelatin solution is lightly wiped over a frosted image and allowed to dry. The image is then lightly wiped with tissue paper, such that the ink is retained only in the frosted areas. When a piece of adhesively coated plastic tape is pressed against the image it removes the ink to form a continuous tone image. A replica of a frosted image for use in printing can be formed by applying softened wax, resin or gelatin to the image, hardening and removing to form a mould for casting the replica.

Patent ES-344209-A1 (ES)
Title: Electronic switching circuit
IPC: H03K17/60
Filed: 1967-08-18
Abstract: In a circuit in which the on and off state of an electronic switch is controlled by an oscillator, excessive switch current causes a second electronic switch to damp the oscillator and reduce or interrupt the switch current. One or other of the transistors T5, T6 oscillates, according to the polarity of the input signal, and the output from its winding 1 is rectified to bias the corresponding transistor T1, T2 conducting whereby the negative or positive supply is - U, + U connected to output terminals A. The output current flows through a small resistor R1 or R2 and if, for example, the current through R1 is excessive the voltage thereacross renders a transistor T3 conductive. This damps the output circuit of the oscillator, reducing the drive to T1 and thus the current therethrough. Damping transistor T3 is reverse biased by a potentiometer R3, R5 in dependence upon the voltage across the load so that if the load is short-circuited the reverse bias is reduced and a small current through R1 is sufficient to render the damping transistors T3 conducting. A capacitive load would draw a large current when the transistors T1 and T2 switch on and capacitors C4 and C5 prevent this current rendering T3 and T4 conducting. Diode D1 protects T3 against excessive reverse base voltage, D3 provides a threshold voltage and D1, which alternatively may be connected across T1 protects against interference voltages received from the output line connected to A. A capacitor in the input circuit C1 slows conduction changeover to prevent both output transistors conducting together. In Fig. 1 (not shown), the damping transistors T3 and T4 are replaced by thyristors and these so reduce the output of the oscillator as to cause transistors T1 and T2 to cease conduction.
Patent ES-344476-A1 (ES)
Title: Improvements in or relating to Oscillators
IPC: H03B5/32
Filed: 1967-08-17
Abstract: In an oscillator having a crystal tuning means CR comprising a crystal body CW coupling two resonators, one resonator PR is connected in the feedback path of an amplifier, e.g. transistor TR, the other resonator SR is adapted to supply output signals to a load network LN and the coupling is such that depending on whether the other resonator SR is terminated by a low or high impedance the resonators pass energy over substantially only a first or a second pass-band respectively. The trimmers CT 1 and CT 2 tune the primary and secondary resonators PR and SR to the same operating frequency. The coupling between the resonators PR and SR may be critical or less than critical and is varied by adjusting the mass loading of the electrodes E1-E4 or the spacing between electrodes. Frequency drifts of the oscillator tuning relative to the filter tuning due to temperature changes are avoided by forming the resonators PR and SR on the same crystal body.
