Abstract: ABSTRACT OF THE DISCLOSURE    A multiple pitch generator, in particular a chime generator, incorporated in an electronic organ of the multiplexed variety wherein the keyboard is scanned and a cyclically recurring serial data stream produced wherein keydown pulses appear in time slots corresponding to depressed keys of the keyboard.  The chime gener-ator produces a plurality of tones in response to the actuation of a single key of the solo keyboard, for example, wherein the tones are those necessary to closely simulate a chime sound.  This is accomplished by sequentially passing the serial data stream containing the keydown pulse through a series of shift registers which insert in the data stream pulses in subsequent time slots corresponding to the next three lowest tones making up the chime.          Since a true chime tone also includes a note five notes above the note played, the partial chime data stream is delayed five time slots and this data stream is summed with the initial data stream carrying the original keydown pulse in the time slot for the note played so as to position the additional pulse in its proper loca-tion ahead of the pulse for the actuated key.  In order to then transpose the pulses in the data stream back to their proper positions for the key played, the latching pulse for the demulti-plexer is delayed five time slots.

Abstract: ABSTRACT OF THE DISCLOSURE An external combustion engine is disclosed of the type including two or more circular rotors rotatably supported, one of the rotors acting as a power rotor and rotating in tangential contact with the other sealing rotor.  The power rotor is formed with a radially projecting piston passing into a mating recess with the sealing rotor at a corresponding circumferential location.  Steam or other working fluid is ad-mitted via an intake port located opposite one face of the power rotor to cause rotation of the power rotor by expansion of the fluid in a working chamber defined by the space behind the piston.  As the power rotor continues to rotate, the work-ing chamber passes into communication with an exhaust port preparator to another power stroke.  A vacuum relief port is provided at an intermediate location which relieves any vacuum condition which develops behind the piston during part throttle operating conditions of the engine.  A pressure balancing groove is located on a face of the power rotor and pressurized with working fluid to balance the pressure acting on the power rotor by the location of the intake port on the opposite face of the power rotor,  An absorber chamber is provided downstream of the throttle valve and upstream of the intake port to smooth out the pressure forces created by intermittent flow of fluid through the intake port.  An elliptical port throttle valve design is disclosed which minimizes the wire drawing effect of the working fluid acting on the valve member during opera-tion of the valve.  A special rotor sealing surface treatment is disclosed comprising a series of slight depressions or holes formed in the mating faces of the power rotor and which gen-erate a sealing due to condensation of the escaping steam in the surface indentations.

Abstract: ABSTRACT OF THE DISCLOSURE         In the continuous casting of steel by a mould equipped with electromagnetic stirring means for electro-magnetically stirring the molten steel in the mould, it is desirable that the upper end surface of the electromagnetic stirring coil is positioned at the same level as the liquid steel in the mould or as close an possible to the liquid steel level, in order to obtain a sufficiently high stirring effect.  To comply with this demand, a cooling box (1) having therein the electromagnetic stirring coil (6), cooling water supply system and a cooling water discharge system, comprises a cooling wall (9) for a direct contact with the molten steel (12) and constituting at least one wall of the mould.  The cooling wall (9) is provided at its inner side with a plurality of cooling water passages (10) for evenly distributing the cooling water, and the chamber (2) for housing the electro-magnetic stirring coil (6) is disposed such that the upper end of the electromagnetic stirring coil (6) takes the same level as the liquid steel (12) surface in the mould.  The water discharge chamber (4) is disposed just under the coil housing chamber and the water supply chamber (3) is placed just under the water discharge chamber (4), so that the cooling water is supplied through the supply chamber (3) and is then discharged through the discharge chamber (4) after flowing through the cooling water passages (10) to effectively cool the cooling wall.  The portion of the rear wall of the cooling box corresponding to the coil housing chamber, opposite to the cooling wall, is provided with an opening large enough to permit the electromagnetic  stirring coil (6) is to pass therethrough.  The electromagnetic stirring coil (6) attached to a coil mounting plate (7") which plays also the role of a lid for closing the opening and the rear wall of the coil housing chamber.  Therefore, the electromagnetic stirring coil (16) can easily  be mounted and dismounted together with the mounting plate (7') into and out of the cooling box (1) to permit saving of time and labour in various protective maintenance works for the electromagnetic stirring unit (6) including the coil.
