Abstract: ELECTRONIC PIANO CIRCUIT            Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to an electronic musical instrument of the keyboard type used to electronically reproduce piano sounds.  The circuit has a velocity semitone circuit to vary the amplitude of the piano voice in response to the velocity of the downward movement of the key.  A master generator and dividers are provided in combination with gates for producing a fundamental square wave frequency and the second and fourth harmonics thereof, in re-sponse to the actuation of a given key on the keyboard.  One circuit arrangement includes gates for combining the fundamental frequency and the second and fourth harmonics in a predetermined time relation to produce the zero, attack, peak, and decay characteristics of a piano voice as actually produced by a piano string.  Amplitude limiting circuit  are coupled to the foregoing circuit for controlling the amplitude of the harmonics in response to predetermined values so that mixing of the fundamental frequency and the second and fourth harmonics along predetermined points of the piano voice characteristics curve will more accurately reproduce electronically the sounds of a piano.  Another circuit arrangement provides a gate for rapid recovery of the piano circuit so that the keys can be actuated in rapid succession.

Abstract: ABSTRACT OF THE DISCLOSURE         A flush tank system includes an elongated tank supported at the opposite ends thereof by a pair of arcuate-shaped rockers which rest on the upper surfaces of a pair of support frames.          The tank normally assumes an upright position with one of a pair of relatively slightly curved portions of each rocker resting on top of the support frames when the tank is empty and when the tank is being filled with a fluid such as water through an open-ing in the top thereof.  The non-uniform cross-section of the tank causes the center of gravity of the water to shift laterally to a point at which the opposite rockers roll from the relatively slightly curved portion on which they are resting over a rela-tively greatly curved portion thereof to the other relatively slightly curved portion, thereby rapidly rotating the tank into a tipped position and pouring the water out of the tank opening.          With the water discharged from the tank, the tank rotates back to the upright position where refilling of the tank with water may be resumed.

Abstract: ABSTRACT OF THE DISCLOSURE      A programmable communications controller having a microcomputer system for buffering and controlling data communications between a communication processor and a plurality of input/output (I/O) ports of the microcomputer system to which ports/terminals can be connected directly, or indirectly, by digital data communication lines.  The random access memory of the microcomputer system is divided into blocks of addresses of locations in which digital data can be stored  One of these blocks is designated as a service block.  The service block in turn is divided into sectors, one for each I/O port to which is connected a communication line, for example.  Each sector in the service block is adapted to have written into it and read from it data unique to the servicing of a given communication I/O port and the communication line or data terminals connected to that port.  The microcomputer system of the controller is provided with an automatic addresser which is under the control of the microcomputer system.  The automatic addresser steers memory commands addressed to the service block to the sector of the service block assigned to the communication I/O port being serviced by the microcomputer system at that time by substituting the address of the communication I/O port being serviced for the address applied to the sector address lines of the address bus by the microcomputer system.  The automatic addresser also steers, in a similar manner; I/o commands from the microcomputer system to the communication I/O port being serviced by the microcomputer system at that time by substituting the address of the port being serviced for the address of whatever I/O port is applied to the address lines of the microcomputer system.

Abstract: TITLE:  SHIFTABLE CHANGE SPEED         TRANSMISSION UTILIZING IMPROVED BLOCKER AND JAW CLUTCH ASSEMBLY                    INVENTOR: ELMER A. RICHARDS                  A B S T R A C T     Improved change speed gearing utilizing an improved blocker means for effecting engagement of the jaw clutch associated with the low speed gearing of a simple transmission, or with the low speed gearing of the main transmission section of a splitter type compound transmission.  A transmission having an input shaft driven by a one-way prime mover, a main shaft and at least one countershaft, and including pairs of shiftable gears arranged on and cooperatively between said shafts, is provided with positive clutches, preferably spring loaded jaw clutches, for effecting connection to one of said shafts of a selected one gear of a selected one of said pairs of said gears upon the achievement of substantial synchronization between such gear and such shaft.  Blockers are provided for protecting the positive clutch teeth from excessive wear during such shifting.  One of said blockers, preferably that blocker associated with either the positive clutch for engaging the low speed pair of gears in a simple transmission, or that blocker associated with the positive clutch for engaging the low speed pair of gears in the main transmission section of a splitter type compound transmission, is effective to sense only one type of nonsynchronous condition, namely, that condition corresponding to one of the clutch members overspeeding the other clutch member in a given direction of rotation.  Sensing of the other type of nonsynchronous condition, namely, the other clutch member overspeeding the one clutch member, has been found to be, as a practical matter, unnecessary in certain situations such as, for example, the low speed gearing of a simple transmission as it is not possible to upshift into the low speed gear of a simple transmission.  In other situations, it may be desirable to utilize an alternate form of improved blocker in connection with the high speed gearing of a simple transmission, or the high speed splitter range of a splitter type compound transmission, which is effective to sense only one type of nonsynchronous condition, that condition wherein the second mentioned clutch member will overspeed the first mentioned clutch member.  The provision of blockers effective to sense only one type of nonsynchronous condition, and effective to prevent or block a clutch engagement only upon the sensing of that one type of nonsynchronous condition, is an improve-ment since the possibility of such blocker being incorrectly positioned or sensing a false nonsynchronous condition is substantially reduced or eliminated.
