| 123 | Electronic pipe organ control system | US747536 | 1976-12-06 | US4092895A | 1978-06-06 | William P. Zabel |
| A solid state electronic relay system for a pipe organ having at least one input register connected to one or more organ manuals, respectively, to receive parallel input signals therefrom, and respectively convert same into a time based serial digital signal wherein each note of the keyboard occupies a particular interval of time in the digital signal. The serialized signal of an input register propagates through a digital delay line at a predetermined clock frequency. Selected ones of the delayed digital signals provided thereby are tapped to derive octave and mutation pitch signals. Accessory circuits receive the serialized digital signals and using combinational and sequential digital techniques modify the digital signals to provide reiteration, pizzicato, sostenuto and the like effects. The tapped signals and modified signals are selectively combined with logical gates under the control of the organ "stops" to provide the unification and accessory functions. The combined digital signals are routed to control specified organ pipes through a plurality of rank drivers which receive the serialized signals and produce a plurality of periodically updated parallel signals therefrom to effect sound reproduction in response to the signals generated by the organ manuals, stop keys, and accessory circuits. | ||||||

| 126 | Chest valve for pipe organs | US3795170D | 1972-12-29 | US3795170A | 1974-03-05 | KLANN P |
| The outlet opening of the air chest is provided with a sleeve for supporting the organ pipe externally of the chest and which acts as a valve seat for the flexible resilient diaphragm of the chest valve. The diaphragm forms one wall of an auxiliary chamber located beneath the sleeve. An electro-magnetic valve controls the communication of the auxiliary chamber to the atmosphere or the air under pressure in the chest. When the auxiliary chamber is in communication with the interior of the air chest the pressures on opposite sides of the diaphragm are equalized around the sleeve and the pressure differential between the atmospheric pressure in the sleeve and the air under pressure in the auxiliary chamber maintains the diaphragm in sealing engagement with the sleeve. When the auxiliary chamber is in communication with the atmosphere, the pressure differential acting on the diaphragm will move the diaphragm away from the sleeve allowing air under pressure to escape from the chest through the sleeve to the pipe of the organ. The chest valve is preferably mounted on the underside of the air chest externally thereof with the diaphragm exposed to the interior of the chest for cooperation with the sleeve.

| 128 | Chord organs | US3698276D | 1970-12-03 | US3698276A | 1972-10-17 | MARTIN HAROLD B; ROGG HERMAN O |
| In an improved chord organ of the type which includes base and keyboard sections having corresponding reed assemblies provided with openings that are normally closed by extending pallets of keys operative by a user, a spring device is provided for normally urging the key pallet against its reed assembly opening. The spring device includes a plastic unitary body having a plurality of compression fingers extending therefrom for contact with the pallets, there being relative sliding movement between the fingers and their respective pallets during movement of the pallets between open and close positions with their reed assembly openings. The organ also features an improved gasket for each reed assembly, said gasket including a plastic unitary body which is located over the top of the reed assembly and possessing an inherent tacky surface for adhering thereto. The organ also features a tonal device which includes a single molded plastic body having a plurality of uniquely arranged pivotally mounted baffle plates located adjacent the sound slots of the organ, said plates being movable with respect to the slots to cause the tonal sounds emanating therefrom to range between a brassy and muted quality.

| 129 | Vacuum pump operated musical instrument | US3670617D | 1971-06-25 | US3670617A | 1972-06-20 | HAILE ERNEST |
| A vacuum pump operated musical instrument is herein described which includes a hollow cylindrical body. The body is formed to define at least one aperture in the cylindrical wall thereof. The hollow body is open at one end and closed at the opposite end. A piston is slidably mounted within the cylindrical body for reciprocation past the aperture. As the piston is moved past the aperture, in a direction from the closed end to the opened end of the hollow body, the piston draws a vacuum and then suddenly communicates that vacuum to the ambient through the aperture. Air rushing in from the ambient into the vacuum space is acted upon the size and configuration of the aperture to form an audible sound. A second piston arrangement may be disposed between the aperture and the closed end of the hollow body. The second piston arrangement may be manually positioned to vary the volume of the vacuum retaining space. The adjustment of the volume of the last mentioned space is operable to controllably vary the pitch of the sound caused by air rushing from ambient into that space. Alternatively, a sleeve member may be coaxially and slidably mounted over the open end of the tubular shaped body so as to be adjustable with respect to the aperture. Axial movement of this sleeve member is operable to controllably vary the pitch of the sound in response to the position of the sleeve member. A one way valve is mounted within the first piston as a compression relief mechanism when the first piston is moved toward the closed end of the tubular body, before commencing the vacuum stroke. If it is found that the vacuum formed between the two pistons is too great when both pistons are moved in opposite directions at the same time, the compression relief valve may be opened manually by a control mechanism associated with the first piston arrangement to dissipate some of the vacuum.
