Abstract

1,233,438. Inducing sleep. SABA SCHWARZWALDER APPARATE-BAU-ANSTALT AUGUST SCHWER SOHNE G.m.b.H. 20 May, 1968, No. 23983/68. Heading A5R. [Also in Divisions G4 and H3] Apparatus for tranquilising or inducing sleep comprises an audio frequency oscillator 1, the output of which is amplitude-modulated at 2 by a low frequency sine wave from an oscillator 3 before being fed to an amplifier 4 and loudspeaker 5. The modulating oscillator 3 is also fed to a D.C. amplifier 6 which controls the brilliance of a lamp 7. The modulator 2 and D.C. amplifier 6 are repetitively turned on and off gradually by means of an electronic timer 9. The amplitude-modulated light from lamp 7 is preferably passed through a blue filter 8. Oscillator 1 preferably provides a sine wave of a frequency from 40 to 80 c/s whilst the period of the sinusoidal output of oscillator 3 may be in the range of 3 to 12 seconds. Two loudspeakers 5 may be employed and fed with waves differing in frequency by 0.5 to 2 c/s. Transistor amplifier and time delay switching circuits are described (see Division H3).
