Title: Speech analysis and synthesis apparatus
Inventor: TAGUCHI TETSU
IPC: G10L19/00
Filed: 1979-03-29
Granted: 1982-05-18
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a speech analysis and synthesis apparatus having an analysis unit adapted to quantize the characterizing parameters of a speech signal at mutually different quantization steps depending on whether the speech signal represent a voiced sound or an unvoiced sound, and a synthesis unit adapted to decode the quantization output from the analysis unit to repro-duce the characterizing parameters.  The unit subtracts a short-term mean value of environment noise from the short-term mean value of the sum of the ambient noise and the speech signal to provide the short-term mean value of the speech signal.  The discrimination between the voiced and unvoiced sounds employed in the analysis unit nonlinearly converts decision parameters which have extremely different variance of occurrence rate dis-tribution characteristics between voiced and unvoiced sound used for the voiced-unvoiced decision equation, and analyzes the mixture of the environment-voice-representing signal and known voiced or unvoiced sound to determine the coefficient and thresh-old values of the voiced-unvoiced decision equation, thereby to determine the voiced or unvoiced sound based on the coefficients and threshold values.  The apparatus requires reduced amount of transmission information without degrading the quality of synthesized speech sound.

Abstract: DETERMINING THE WATER CUT AND WATER SALINITY IN AN OIL-WATER FLOWSTREAM BY MEASURING THE      SULFUR CONTENT OF THE PRODUCED OIL    (Texaco Docket No. D#76,533-F) ABSTRACT OF THE DISCLOSURE:          Fluid in a pipeline or container at a refinery or at any of various petroleum producing operations is bombarded with neutrons and high energy gamma rays resulting from cap-ture of thermal neutrons are detected.  The spectra of the detected gamma rays are then analyzed to determine the rela-tive presence of the elements sulfur, hydrogen and chlorine.          From the sulfur measurement, the oil cut of the fluid is de-termined, enabling the water cut to be determined.  From the determined water cut, water salinity can also be determined.                             -I-

Abstract: Abstract:          A cylinder lock includes two barrels (23, 37), a first (23) carrying tumblers (30) that abut internal shoulders (36) of the lock casing (2) to obstruct clockwise 'unlocking' rotation only, and the second (37) carrying a single tumbler (43) which obstructs only counter-clockwise 'locking' rotation by abutment with a shoulder (48) of a rear-end casing-cover (8).  A key (5) inserted through a keyhole-defining assembly (11, 16, 21) withdraws the first-barrel tumblers (30) during initial clockwise turning from the insertion position, and the second-barrel tumbler (43) during initial counter-clockwise turning. Lost-motion coupling between the barrels (23, 37), provided by lug-in-slot (38, 39) interengagement, enables clockwise turning of the second barrel (37) with the key (5) relative to the first barrel (23) during withdrawal of the first-barrel tumblers (30), and corresponding counter-clockwise turning of the first barrel (23) relative to the second (37) during withdrawal of the second-barrel tumbler (43).  Lug-in-slot coupling (22, 24) between the keyhole-defining assembly (11, 16, 21) and the first barrel (23) similarly allows initial slip for clockwise key-turning.  A coiled spring (42) opposes resiliently second-barrel turning in both directions.

Abstract: FIRE HYDRANT NOZZLE ASSEMBLY     ABSTRACT OF THE DISCLOSURE       A fire hydrant nozzle assembly which permits a bronze fire hydrant nozzle to be readily and simply attached to a cast iron hydrant barrel without the use of lead caulking, screw threads, or other methods generally requiring machining.  Un-intentional removal of the bronze nozzle as a result of the application of relatively high torque typically required to remove a protective cap is effectively prevented.  To provide these features, a bronze nozzle member is retained within a hydrant boss member by means of a bayonet type or breech lock type mechanism involving cooperating lugs, and a resilient seal such as an O-ring is provided.  For locking the nozzle member in its installed position, a pin element passes through a pair of corresponding apertures in confronting surfaces of the boss and nozzle members.  The installed position is positively defined by respective locating engagement surfaces carried by the boss and nozzle members, which surfaces serve to limit rotation.  The corresponding apertures can always be aligned even though they are pre-formed or pre-drilled. Preferably, the locating engagement surfaces are configured and positioned such that locking rotation of the nozzle following insertion into the boss occurs in a direction opposite to the direction of the threads on the outlet end of the nozzle such that when the nozzle cap is removed the locating engagement surfaces resist the torque involved.

Abstract: SADDLE FOR BAR OF BAR-TYPE WEIGHT          Abstract of the Disclosure:         A saddle for the bar of a bar-type weight has a bar-receiving portion, arms that incline upwardly and away from that portion, and a socket-forming portion which defines a socket that extends downwardly relative to those arms to tele-scope downwardly over the upper end of a rod-like support; and that saddle is unitary in nature and is wholly devoid of joints between any of the bar-receiving portion, the arms and the socket-forming portion.  The bar-receiving portion has a part thereof which is located above the level of one edge thereof so a gap will always exist between that edge and the bar of the bar-type weight.  The upper ends of the arms have horizontally-directed outwardly-extending lips that increase the effective area of the saddle which can be engaged by the bar of a bar-type weight without directing that bar away from that saddle.

Abstract: ABSTRACT OF THE DISCLOSURE        Nuclear fuel elements or slugs are removed from the nuclear reactor cores and subjected to inspection, according to the invention, by introducing a plurality of such elements into a submerged inspection vessel which is then closed, the liquid driven out by compressed air and deionized water (deionate) circulated through the inspection vessel at a constant rate.  A portion of the deionzed water is branched from the circulating stream at a constant rate and the activity of at least one fission-product nuclide is determined continuously to plot the activity versus temperature, thereby signaling a possible defect in the shell of a fuel element.  In addition, ultrasonic vibration is applied in the inspection vessel to the fuel elements so  that deposits on the exterior thereof are released into the deionate whose circulating path includes a filter and an ion-exchange column for removal of such deposits.
