Title: Audio frequency signal changing circuits
IPC: H03G5/02
Filed: 1972-08-08
Abstract: 1410771 Reproducing music; stereophonic systems NIPPON COLUMBIA KK 8 Aug 1972 [11 Aug 1971 30 Nov 1971 14 April 1972 25 May 1972] 36996/72 Headings H4J and H4R An audio frequency band such as a voice frequency band contained in an audio frequency signal from a pre-recorded tape, record radio or T.V. is selectively attenuated or removed and a second audio frequency signal, e.g. from a microphone, is added to the reproduced signal in place of the attenuated or removed band. This second audio frequency signal has a range occupying at least part of the attenuated or removed band. A switch is responsive to the presence of the second audio frequency signal to provide a control signal for bringing the attenuating or removing means into operation. The switch includes a delay circuit to delay provision of the control signal for a predetermined time after detection of the second audio frequency signal to ensure that transient signals generated during switching are not present in the mixed signal. Stereophonically related signals IL, IR (Fig. 5) are applied to speakers 4L, 4R through line amplifiers 3Lb, 3Rb, respectively. Signal IL is also connected to speaker 4L through a band stop filter (122) (800 to 5000 Hz) and line amplifier 3La. Similarly signal IR is connected to speaker 4R through a similar band elimination filter 12R and line amplifier 3Ra. The output from a microphone 6 is supplied through an amplifier 7 to a band stop filter 17 (800 to 5000 Hz) and then through a high pass filter 19 (3000 + Hz) to a buffer amplifier 20 and rectifier circuit 21. When circuit 21 provides an output, a Schmidt trigger 22 actuates a switching circuit 23. The arrangement is such that, when no sound is applied to the microphone 6, switching circuits 23 grounds the power source terminals of amplifiers 3La and 3Ra so that signals IL, IR are supplied to speakers 4L, 4R by amplifiers 3Lb, 3Rb. When voice signals are applied to microphone 6, switching circuit 23 is actuated to ground the power source terminals of amplifiers 3Lb and 3Rb while the power source terminals of, amplifiers 3La, 3Ra are energized. Thus signals IL, IR after having their intermediate frequency components removed, are mixed with the signal from microphone 6 and amplified by amplifiers 3La, 3Ra. Howling is unlikely to occur, but can be removed by making microphone 6 inoperative momentarily or stopping supply of sound momentarily. A band pass filter 17a, may be inserted. Clicks are heard from the loud-speakers 4L, 4R at the time of change-over of switching circuit 23 or if the sound input to the microphone 6 is momentarily interrupted. These clicks are eliminated in a circuit, Fig. 6 comprising a capacitor 46 having a time of charge or discharge sufficient to delay changeover of amplifiers 3La, 3Ra or 3Lb, 3Rb until. the Schmidt trigger 22 and switching circuit 23 are operated.

Abstract: 1510639 Road-traffic signals GEC-ELLIOTT AUTOMATION Ltd 23 May 1975 [27 Aug 1974] 37437/74 Heading G4Q Digital traffic control appparatus for an operating sequence of plurality of traffic lights energized from A.C. supply through relays, includes random phase-modulation of relayswitching signals with respect to A.C. supply. Relay contact wear is thereby reduced. In an embodiment, 50 Hz mains is fed via full-wave rectifier 4 and Schmitt trigger 5 to monostables 6, 7 to produce 100 Hz clock pulses CL1, CL2, A counter 8 reduces CL1 pulses to 1 Hz for a counter 10 which produces a binary output representative of pulses counted up to a maximum of sixteen, on outputs a, b, c, d. When the binary number on those leads corresponds to a selected decimal number on one of sixteen leads selected by a lamp timing selection decoder 19, a device 11 produces an output for AND gate 13; thereby pulses from the latter are at times dependent on the selected decimal number and occur at the same point in the mains cycle. In accordance with the invention a randomizing stage 2 is added and comprises a store 14 the storage period of which is controlled by an astable circuit 15. Counter 10 is reset from store 14 each time a pulse issues from gate 13. The randomized timing pulses from store 14 pass to a counter 17. In an alternative arrangement the outputs of lamp pattern selection decoder 18 are randomized by a plurality of circuits 2, one for each lamp. In a further alternative arrangement the mains input is phase-modulated. The A.C. input in a further arrangement is from a crystal-controlled oscillator not synchronized with the mains.

When a door a is raised to the position shown a bellcrank b moves slides f and g to the right so that the object falls into a chamber e. Movement of slide f also sets a time-delay device j. The presence of the object in the chamber e is detected by a photocell fc and lamp o which de-energises a relay V so that the slide f moves to the left and closes the top of the chamber e. If the lamp or photo-cell fail, the slide f moves as if an object were present. After an adjustable time has elapsed the delay device turns a bellcrank m to release the slide g which allows the object to fall into the safe. However, if the object is hot, a bimetal contact bn de-energizes a relay which alows a bell-crank i to pivot, thereby preventing the slide g from moving to the left until the object has cooled down.
