Title: Tone generating apparatus for musical instrument
IPC: G10H1/055
Filed: 1970-03-24
Abstract: 1,245,565. Envelope shaping apparatus. WURLITZER CO. 24 March, 1970 [26 March, 1969], No. 14256/70. Heading G5J. [Also in Division H1] A piezo transducer 22 is impulsively excited by a hammer 14 in a piano-type action, and the voltage so produced causes a capacitor 62 to be charged, the latter discharging through resistor 60 alone when damper contact 28 is open giving profile 82, or through resistors 60 and 64 when the contact 28 is closed giving profile 86, the resulting signal being used to provide an envelope for oscillations from the generator 68. The loudness of the sound produced is thus dependent on the pressure on the key (10), Fig. 1 (not shown), and the damper contact 28 is opened when the key (10) is depressed, giving a sustaining effect. The capacitor 62 is charged via a Darlington pair 54, 56, normally cut-off. The time constants of the discharge circuit are varied with pitch, to imitate the damping characteristics of a piano. The piezo transducer (22), Fig. 3 (not shown), is a disc of barium titanate, with silvered faces (36, 38) and is mounted on a metallic rail (20), Fig. 2 (not shown), by a plastics stud 24 resiliently held by clip 48, or by an integral rubber stud (24a), Fig. 5 (not shown). The hammer 14 strikes the head of the stud, and in the latter case, lateral spreading of the head (44a) gives increased voltage output. The damper base (26), Fig. 1 (not shown), may be fixed to, or integral with the rail (20).

Fibre tufts, are supplied to a number of textile machines e.g. carding engines 7, 8 from a closed circuit conduit 6, 10 (see also Fig. 4, not shown) carrying fibres in an air stream, each machine having means to divert a portion of the fibres to itself. As shown fibres pass on a conveyor 1 to a rotary condenser 3, are detached therefrom and blown into conduit 6. At each machine there is a lateral branch 9 connected to a funnel 33 (see also Figs. 5 and 6, not shown) the lower end of which is subjected to the action of a fan 32 to draw off a portion of the airstream in duct 6, this air stream passes through screens (31, 31'), see Fig. 5, not shown, to deposit the fibres thereon while the air returns via pump (32) and a filter (35) to duct 6. Moving arms (44, 44') remove the fibres from screens (31, 31') to deliver them to the feeding device (30) for the machine. At the mouth of branch 9 a rotating cylinder 11 has vanes which project into duct 6 and remove fibres therefrom; the bearings of the cylinder are on slides so that the projection of the vanes into the duct may be varied. A false wall (38) (Fig. 5, not shown) at one side of duct 9 is movable so that the cross section of the duct may be varied. Just upstream of each duct 9 is a flap 41 which may be raised by a solenoid 43 to deflect the airstream over the associated duct; the solenoid may be as connected to an overflowdetecting device on the feed device of the associated machine so that the supply of fibres to each machine can be regulated. Cylinders 11 are driven from an electric motor by a belt, rope or chain drive, the pulleys in the drive being exchangable for different cylinder speeds. In Fig. 1, not shown, a second fibre supplying device (2') feeds into duct 6 to effect a mixing of different fibres.
