Patent ES-347474-A1 (ES)
Title: Apparatus for indicating tuning of frequency-modulated signal transmissions
IPC: H03J3/14
Filed: 1967-11-22
Abstract: The presence of amplitude modulation components indicating inaccurate adjustments in reception of f.m. signals is indicated by having in the receiving arrangement a demodulator to detect frequency components, which are selectively applied to a peak to peak detector responding to any amplitude modulation to produce a signal which is applied to an indicator circuit already indicating signal strength. A difference in the reading between when the signal is applied and not applied indicates the presence and size of a.m. components. A meter M1 is connected between the emitter of the first stage Q1 of the I.F. amplifier and the emitter of a transistor Q2, which carries a constant current when switch S1 is open the circuit constants may be such that the meter indicates zero when no signal is present and full scale deflection when the input signal is of maximum expected amplitude. The output of the I.F. amplifier 11 is rectified by a diode D1 to provide AGC voltage which fluctuates in accordance with any amplitude modulation present and is fed through switch S1 when closed, to the base of transistor Q2. The output of this transistor feeds a peak detector D2, D3 which biases the transistor and varies the emitter potential. The deflection of meter M1 is therefore reduced, in accordance with the amount of amplitude modulation present in the I.F. signal. In a modification, Fig.2 (not shown), the meter Ml is connected between a fixed potential and the emitter of Q2 the AGC line is coupled to the base of Q2 through a resistance (R16), and a capacitor (C6) connected to the base is coupled by a switch (S2) either to the point 17 or to earth. Thus in one position of the switch a signal representing amplitude modulator is coupled to the base of Q2, and in the other position it is filtered out.

Title: Impression control mechanism
IPC: B41J7/94
Filed: 1967-12-27
Abstract: A power driven typewriter, in which a selected serrated cam 41 coacts with a continuously driven power roll 47 to effect an impression, includes impact adjustment mechanism responsive to a case shift wherein a greater striking force is initially applied to the type bar 11 when in the upper case and a stop finger 61 responsive to the case shift disengages the cam from the power roll after a time of contact such as to compensate for the increase in striking force applied, adjustment also being effected during a case shift operation. The impression density of each character is controlled by a finger 61 resting on an individually adjustable upper or lower case stop screw 57, 59 by engaging a heel 63 of the cam 41 to disengage the cam from the power roll. The stop screws 57, 59 are mounted on a bar 56 which is rocked about a pivot 71 by the case shift mechanism. The position of the bar 56 is adjustable by an impact control lever (105), Fig. 2 (not shown), for collective adjustment of the impression density as described in Specification 1,169,810. The case shift mechanism rotates a plate 23 mounted on a shaft 25 to move the pivots 13 of the type bars through linkage (not shown). A pin 79 on the plate 23, moves a link 73 after a delay caused by lost motion in a slot 83 by sliding in a slot 85, the link 73 being connected to the bar 56 through a bracket 77, thus rocking the bracket about the pivot 71. The delay enables the impression density to be correct when case shift and character keys are redepressed simultaneously.

Patent ES-383379-A1 (ES)
Title: Multiplex fm transmitter
IPC: H04B7/208
Filed: 1970-09-03
Abstract: A first variable attenuator is coupled between the FDM baseband source and the FM modulator. The output signal of the first attenuator is RMS detected to provide a control signal for this attenuator to adjust the amplitude of the baseband signal applied to the FM modulator and, hence, the frequency deviation thereof. An increase in frequency deviation enables a reduction in the EIRP (effective isotropic radiated power) for the same S/N, or an increase in S/N for the same EIRP. A second variable attenuator controlled by the same control signal operates in an inverse fashion, as compared to the first variable attenuator, on the carrier amplitude to maintain a constant S/N ratio.
