Time compression of audio signals

Abstract: The invention pertains to a technique for time-compressing audio signals without disturbing the relative position of the audio samples through the use of a time buffer store and a subsequent FM recording of the time-compressed audio signal in a format similar to video signals and the subsequent demodulation of the FM signals and time expansion of the signals to produce the original audio signals. The use of FM modulation and demodulation of a type similar to that used with video information for recording and transmitting time-compressed audio information permits common processing of audio and video information and the utilization of standard video transmission and video tape and video disc recorders to accommodate audio as well as video information.

Low parasitic capture fuel assembly structure

Abstract: The basic fuel assembly structure for a nuclear reactor comprises a skeleton made up of individual hollow tubes composed of a zirconium base alloy, such as Zircaloy, and held in place by Inconel or stainless steel grids disposed between stainless steel end nozzles at the top and the bottom of the structure. The tubes serve as guide thimbles for cylindrical control elements strategically located in a square array of fuel rods held in place by spring fingers on the "egg-crate" grids. The guide thimbles are attached to the top and bottom nozzles and the grids by mechanical joints without welding dissimilar metals.

Effect of Alumina Content on the Oxidation of Hot‐Pressed Silicon Carbide

Abstract: The oxidation behavior at 1370°C of dense SiC, hot-pressed with the aid of Al2O3, has been investigated as a function of Al2O3 content. Increasing amounts of the Al2O3 hot-pressing aid increased the oxidation rate. Observations of the oxide surface show that a glassy phase (indicating formation of a liquid at the oxidation temperature) containing Si, Al, Fe, and K forms over the residual Al2O3 in the hot-pressed material. It is suggested that the oxygen transport through an impure aluminosilicate liquid is faster than that through a pure SiO2 scale, thus causing an increased oxidation rate.

Abradable coating applied with cold spray technique

Abstract: A cold spray process (20) for applying an abradable coating (16) to a substrate material (12). A bond coat layer (14) and/or an abradable coating material layer (16) are applied to a substrate (12) by directing particles of the material toward the substrate surface at a velocity sufficiently high to cause the particles to deform and to adhere to the surface. Particles of the bond coat material may first be directed toward the substrate surface at a velocity sufficiently high to clean the surface (24) but not sufficiently high to cause the particles to deform and to adhere to the surface.

Experimentally determined stress-intensity factors for single-edge-crack round bars loaded in bending

Abstract: Dimensionless stress-intensity factors were determined for single-edge-crack solid and hollow round bars loaded in bending These factors were calculated from experimental compliance (inverse slope of load-displacement curve) measurements made on round bars loaded in three-point bending The compliance specimens had span to diameter ratios of 667 and 333, and measurements were made over a range of dimensionless crack lengths from 0002 to 070 The tests were made using 3-in (76-mm) and 6-in (152-mm) solid and hollow round bars notched on one side; the hollow bars had an inner to outer diameter ratio of 033 A comparison was made with data in the literature for rectangular bars; for ana/D of 00001, the dimensionless stress-intensity factor for a solid round bar is 13 vs 20 for a rectangular bar
