Abstract: A note clock generation circuit generates note clock pulses in correspondence to a note name of a tone to be generated. An octave rate data generation circuit generates rate data in correspondence to the octave range to which the tone to be generated belongs. By performing addition or subtraction of the rate data at the timing of generation of the note clock pulses, an address signal is generated. A tone generator generates a tone waveshape in the form of amplitude sampled values in response to an integer section of this address signal. An interpolation circuit performs interpolation between adjacent amplitude sampled values thus generated in response to a decimal section of the address signal. The rate of change of the decimal section of the address signal is changed in accordance with the tone range so that a finer interpolation is made as the tone range becomes lower. By this arrangement, decrease in an effective sampling frequency in the lower tone range can be prevented.

Abstract: A network of adjacent aggregate containing mesh bags provides structural support to the slab or floor of a building. The network, encased in a sheath of plastic film, also functions as a path for air to be directed by a blower. The openings within the network are filled with gravel, sand or earth packs. At the perimeter of the network an air return system leads to the interior of the building. Thus, the blower can circulate air from the building interior through the network and air return system and back into the interior. Air circulating in the network can undergo heat exchange through the plastic film at the interfaces of the slab, the packs, and the underlying ground. Peripheral ground insulation minimizes lateral heat transfer. Preferably the aggregate containing mesh bags have indexing means to indicate their respective heights from above as they rest on a supportive planar surface.

Abstract: Successive stages of a missile are held together by an encircling band jod at its ends by an explosive band separation device. Opposite ends of the band are welded to separable parts which interlock with each other. Since the band is held in tension, inclined surfaces on the separable parts force them from maintaining an engagement so that a retaining cover is needed to hold them together. The retaining cover is held by a pair of balls which diametrically communicate with a longitudinal bore. A piston in the bore keeps the balls in cavities in the retaining cover to hold the separable parts together. A power cartridge detonated by an electrical signal displaces the piston the length of the bore and the balls free of the retaining cover. The retaining cover rotates by a resultant upward force exerted by the inclining surfaces. Freed from the retaining cover the tensile force exerted by the band pulls the separable parts apart to free successive stages of the missile from one another.

Abstract: A training cartridge includes a metallic cartridge case with a case shoulder and dummy projectile having a gas exhaust opening at its front end.

Abstract: Single-sided linear induction motors (SLIMs) suspended in proximity to the rail of a locomotive are energized to increase the effective adhesion between the locomotive drive wheels and the rail in response to the detection of an operating condition in which the tractive effort of the locomotive traction motors is limited by less than optimal adhesion.

One method further employs sand dispensing units activated if the suboptimal operating condition is not alleviated by activation of the SLIMs. Another method uses the sand dispensing units first, and only activates the SLIMs if the suboptimal operating condition is not alleviated by activation of the sand dispensing mechanism.
