Abstract: 1282364 Electronic musical instruments M RANZATO 1 July 1970 [11 July 1969 10 June 1970] 31969/70 Heading G4J An electronic musical instrument for simulating the sound emitted from a stringed instrument comprises an oscillator 18, a preamplifier 17, a set of buttons 3 which, when actuated, apply a diminishing potential to the pre-amplifier, an amplifier 19 and a loudspeaker 20. The frequency of the oscillator is determined by keys 4, which, when depressed, short circuit the respective resistors 13. The diminishing potential is produced by allowing the capacitor 8 to discharge through the preamplifier 17. The note may be terminated by means of the contact 14<SP>1</SP>, which allows the capacitor to discharge direct to earth. When simulating a guitar, the keys 4 may be situated along the neck of a guitar and the buttons 3 may be placed on the sound box of the guitar. Thus each button 3, and its associated set of keys 4 represent each string of the guitar. When simulating a piano, the contact 14 may be omitted, and switches corresponding to the continue and soft pedals may be employed. For a piano, the circuit is modified so that the note sounds when the button is depressed, and not when it is released, as is the case with the guitar.

Filed: 1963-08-14
Abstract: 990,947. Statistical apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 14, 1963 [Aug. 17, 1962], No. 32100/63. Heading G4M. Passage of a record card through a sensing station is timed by detecting the leading edge of the card, counting the number of pulses delivered by a pulse-wheel connected to the record driving mechanism corresponding to the distance travelled by the card in the interval between detection of the leading edge and arrival of the first column at the sensing station, and thereafter counting the number of pulses corresponding to the distance between successive columns. The apparatus shown may be used for timing either of two different types of cards. Pulse wheel PW has two sets of perforations which are sensed photo-electrically at PB 1  or PB 2  to provide a train of pulses the frequency of which is related to the distance between columns of the cards. Switches S 1  and S 2  are set according to the type of card being sensed. Counter TS is normally held at a predetermined count by bi-stable circuit FF 2  and switch S 2 . On arrival of the leading edge of the card at detector RD, FF 2  is set and counter TS counts pulses applied to terminal 1, starting at the predetermined count. When the first column is at a distance from the sensing station equal to the column-spacing; counter TS produces a pulse at output 3 to set bi-stable circuit FF 1  and open gate P, any pulses previously produced at output 4 being blocked. Subsequent pulses from output 4 occur as successive columns reach the sensing station and pass to output terminal 5. After sensing of the card is completed, a control circuit comp resets FF 2  and FF 1 .
