Abstract: Cette invention concerne un dispositif intra-vaginal pour porcs, lequel possède une forme et une taille permettant de le placer dans la voie vaginale en travers de l'anneau hyménéal de l'animal, par exemple une truie nullipare, ceci de manière à entrer en en contact avec les deux côtés de l'anneau. Une fois inséré, ce dispositif va libérer de la progestérone sur les deux côté de l'anneau hyménéal, ceci depuis une matrice imprégnée de progestérone qui possède une surface de libération représentant au total au moins 150 cm<2>. Un système à géométrie variable, de préférence pour un contact vestibulaire, assure la rétention du dispositif pour une période d'au moins 7 à 14 jours. Dans un dispositif préféré, on utilise une charge de progestérone de 1,9 à 2,5 g pour 1,2 mm de la surface de libération. Cette charge permet de maintenir un niveau de progestérone dans le plasma sanguin qui équivaut à un niveau de progestérone de plus de 4 ng/ml dans le plasma sanguin d'un animal ovariectomisé. Cette charge permet ainsi d'assurer ou d'accélérer l'ovulation dans les 3 à 5 jours suivant le retrait dudit dispositif.

Abstract: A crop residue spreader for a combine harvester is pivotally mounted to the combine for rotation about a transverse axis. The spreader has a spreading position in which crop residue is spread over a wide area at the rear of the combine.  The spreader is rotatable about the transverse axis to a raised windrowing position to allow the residue to fall to the ground in a windrow for later collection. The disks of the spreader are covered by shrouds above and to the sides to reduce the upward dispersal of the residue. Gas assist cylinders are provided to lift the spreader to the windrow position after which a latch is engaged to hold the spreader there. A  hold down latch operates to hold the spreader in the spreading position in opposition to the gas assist cylinders.

Title: Speech signal decoding method and apparatus
Inventor: MURASHIMA ATSUSHI
IPC: G10L25/90
Filed: 2000-07-27
Granted: 2008-02-05
Abstract: In a speech signal decoding method, information containing at least a sound source signal, gain, and filter coefficients is decoded from a received bit stream. Voiced speech and unvoiced speech of a speech signal are identified using the decoded information. Smoothing processing based on the decoded information is performed for at least either one of the decoded gain and decoded filter coefficients in the unvoiced speech. The speech signal is decoded by driving a filter having the decoded filter coefficients by an excitation signal obtained by multiplying the decoded sound source signal by the decoded gain using the result of the smoothing processing. A speech signal decoding apparatus is also disclosed.

Abstract: - A compressor assembly including a housing, a motor and a compression mechanism disposed within the housing, the compression mechanism driven by the motor. A pulsating discharge fluid flow emanates from the compression mechanism through a first conduit; the first conduit having an outlet which is open to a discharge muffler chamber. A standing pressure waveform is established by the first pulsating discharge fluid flow within the discharge muffler chamber. A second conduit is provided which has an inlet which is open to the discharge muffler chamber and disposed outside the standing pressure waveform therein, and an outlet through which discharge fluid exits, whereby the magnitude of the discharge pulse transmitted by the discharge fluid is attenuated. The present invention also provides a compressor assembly including a compression mechanism and a discharge muffler chamber having a substantially hemispherical inner surface and a central axis. First and second conduits are in fluid communication through the discharge muffler chamber, the openings of the first and second conduits within said discharge muffler chamber are directed substantially towards the central axis and oriented at approximately a right angle relative to each other therealong. A discharge fluid flow is received in the discharge muffler chamber from the compression mechanism via the first conduit. The discharge fluid flow contains pressure pulses of a fast magnitude. The discharge fluid flow is exhausted from the discharge muffler chamber via the second conduit, the discharge fluid flow exhausted from the discharge muffler containing pressure pulses of a second magnitude less than the first magnitude.
