Title: Electronic musical instrument circuit
IPC: G10H1/36
Filed: 1973-05-10
Abstract: 1381223 Electronic musical instrument circuit WURLITZER CO 10 May 1973 [25 Aug 1972] 22406/73 Heading G5J An electronic musical instrument with a plurality of keys on a keyboard comprises a first sound generator having a single oscillator with a group of selectable resistors producing selected notes and a first output circuit; and a second generator with a plurality of oscillators, each with a group of selectable resistors, for producing chord tones and a second output circuit, both output circuits feeding a loudspeaker. Switching the resistors of the second generator's oscillator controls the production of chord tones, which are mixed in its output (transistor) circuit, delivered through a rhythm gate circuit to an audio amplifier cum buffer transistor, denoted in this abridgment by B, and a potentiometer volume control to said audio amplifier. A logic circuit which automatically produces rhythm percussion sounds has a variable resistance controlling the tempo, the rhythm pattern being selected by switches. The individual sounds come from terminals designated " bass drum ", " snare drum ", " cymbal " and " brush ". The bass drum terminal is connected via a diode and transistor amplifier to B. The cymbal, brush and snare drum terminals are connected to a gate logic circuit. Thence the cymbal and brush signals are applied directly, and the snare drum signals via a filter circuit, to B. This filter circuit receives signals from a noise generator and selectively passes intermixed noise signals to reproduce more realistically the snare drum sound. The snare drum terminal is also connected to a 200 Hz output from the logic circuit. There is a variable frequency (0À5-60 Hz) vibrato oscillator circuit producing a triangular wave shape transformed to a sine wave shape by a shaping circuit and connected to two amplifiers operating as a multivibrator connected by a potentiometer to an amplifier. The output from this or a 60 Hz signal from the power supply can be switched on to the first oscillator to frequency modulate it. This amplifier can also be controlled by a pulse by key depression to make the first oscillator tone say change to natural after starting flat. The single oscillator output is delivered via an emitter follower transistor to a selected one of a multiple filter network so that the sound of different instruments, e.g. horn, saxophone, may be simulated, thence through another transistor amplifier and potentiometer to the input of the audio amplifier, which has a filter eliminating extraneous high frequency noise pulses. The gate is controlled by a lightdependent resistor varying according to a rhythm pulse pattern from a light-emitting diode connected to the logic circuit. The power supply and the logic circuit are described.

Filed: 1924-09-29
Abstract: 244,848. Wiegand, W. B. Sept. 29, 1924. Plastic compositions containing indiarubber &c., carbon black &c.-Boots and shoes, especially of the so-called gum-boot class, have their uppers of one composition of rubber throughout prepared from calendered rubber having a high percentage of carbon or lamp black, from 60 to 120 parts carbon to 100 parts rubber, and a small percentage of emollients with or without vulcanizing agents. The parts of the footwear are cut to pattern from the calendered composition, successively mounted on a last and vulcanized together. A suitable composition would be :- Crude rubber 100, sulphur 5, litharge 5, carbon black 80, pine tar 4, and toluol 10 parts. The sulphur and litharge can be replaced by other vulcanizing agents and the pine tar by petroleum jelly or stearic acid, and the toluol may be replaced by xylol or omitted altogether. The rubber is masticated for 15 to 20 minutes, but it is preferable to grind the rubber from 30-60 minutes or even to cool off and regrind for 25 minutes. The carbon black, an emollient such as pine tar, and a solvent such as toluol are mixed and added. The vulcanizing agents are preferably added during the final mixing. The above composition is calendered to the required thickness. Where a part exceeds <30>/1000ths of an inch it is plied up to the required thickness. Leg and toe portions of a boot are calendered two plies, being cut to size one layer at a time. The various parts are placed successively on a last together with a vamp form consisting of osnaburg sheeting covered on both sides with rubber compound. The whole is then vulcanized. Rubber scrap is not discarded, being used over and over again. It is stated that the rubber has combined qualities after vulcanization of high extensibility, high rigidity and high tensile strength.
