Title: Receiver for the reception of single sideband signals having  an unsuppressed or only partly suppressed carrier
IPC: H04B1/30
Filed: 1972-08-23
Abstract: 1329930 Radio receiving circuits; transistor amplifying circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Aug 1972  [26 Aug 1971] 39228/72 Headings H3Q and H3T The invention relates to a receiver for single side-band signals having an unsuppressed or only partly suppressed carrier, comprising a frequency-changer 3, Fig. 1, local oscillator 4, I.F. amplifier 5, automatic gain control circuit 7, and a narrow-band I.F. filter 8 for separating out the I.F. carrier frequency, which is applied to one input of a demodulator 11, to the other input of which the I.F. signals are applied. It is characterized in that detuning means are provided for shifting the resonant frequency of the I.F. carrier filter 8 within the passband of the I.F. transmission channel as a function of the amplitude of the output from the I.F. carrier filter 8. The arrangement is employed because the output of carrier filter 8 is fed-via limiter 9- to a detector 16 which operates muting circuit 17; in tuning such a receiver, at the upper side of the I.F. passband a, Fig. 2, received signals can pass through carrier filter 5 and operate the muting circuit 17, before the a.g.c. comes into operation, and unpleasant noises are produced in the output of the receiver: by shifting the response b of the carrier filter 8 this is avoided. The shifting is performed by an output from the detector 16. The receiver also comprises a 90 degree phase-shifting circuit 13 on the path between I.F. amplifier 5 and demodulator 11, and an A.F.C. circuit comprising a low-pass filter 15 coupling the output of demodulator 15 to oscillator 4. Variable frequency narrow band filter. The carrier frequency filter may comprise cascaded amplifiers 20, 21, Fig. 6, with positive feedback overall by means of resistor 23. A quartz crystal 22 provides negative feedback around amplifier 20 except at its parallel resonant frequency. The resonance frequency is shifted by means of capacitor 24 in series with transistor 25; varying the base bias of the transistor alters the bandwidth at the same time as the frequency is shifted. In a second arrangement, two quartz crystals each resonant at one of the two desired frequencies, are used: a separate transistor in series with each crystal is switched conductive or non-conductive by means of a bi-stable circuit (Fig. 7, not shown). In a further arrangement a quartz crystal shunts to earth the connection between the amplifiers and frequency is varied by means of a varactor diode in parallel with it (Fig. 8, not shown).

An electro-photographic apparatus has a path for recycling an original to be copied the required number of times to produce multiple copies or single copies without recycling. Insertion of an original into the apparatus trips a lever 38 which actuates a switch 40 which causes feeding of a copy sheet from supply (16, Fig. 5, not shown). The copy sheet moves along a path (42) between a pair of drive rollers (44, 46) through a charging station (50) and then through an exposure station (52) in synchronism with an original moving through an illuminating station 48, Fig. 2. The original is then fed out of the machine through rollers 70 in the case of single copy production or is diverted by a movable gate 26 for multiple copies. The gate is actuated by a solenoid (116, Fig. 6, not shown) in a control circuit having a counting solenoid (158) which causes rotation of a ratchet wheel (154) upon each energization. The ratchet wheel (154) is preset by a knob (146) for the required number of copies. A locking mechanism (172) has an extension (174a) which prevents the knob (146) being rotated when the gate is in the return position Fig. 3 (not shown).
