Title: Audio block sequence compiler for generating prescribed duration audio sequences
Inventor: KLINGLER KEVIN C
IPC: G10H1/00
Filed: 1996-09-20
Abstract: An audio block sequence compiler (16) for selecting a plurality of audio blocks to generate a sequence having a duration corresponding to user-prescribed criteria. In a preferred embodiment, a user chooses an audio, e.g., a musical, segment from a predefined audio library (14) and prescribes the duration of an audio sequence. Prior to depositing each musical segment in the library (14), the musical selection is divided into audio blocks that are identified in a corresponding encoding table with characteristics including duration, suitability for being used as beginning or ending of an audio sequence, and musical compatibility with each audio block. Using this characteristic table and the user-prescribed criteria, i.e., duration, the audio block sequence compiler (16) generates a plurality of audio sequences satisfying the user-prescribed criteria which can be reviewed, e.g., played, and/or saved for future use.

Abstract: Diene polymers or copolymers having improved balance between raw polymer viscosity and mixed compound viscosity, useful in tire tread compositions having highly balanced wet traction, rolling resistance, and traction in ice and snow, and fracture properties in the cured and white carbon reinforced states are provided. These diene polymers or copolymers comprise a mixture of diene polymer or copolymer chains containing carbon-tin bonds in the main polymer or copolymer chains and diene polymer or copolymer chains containing terminals derived from hydrocarboxysilane compounds. The diene polymer or copolymers are prepared by first coupling a portion of the living diene polymer or copolymer chains obtained by anionic polymerization using a tin polyhalide coupling agent and then terminating the remaining living diene polymer or copolymer chains using hydrocarboxysilane compounds. The resultant diene polymers or copolymers have improved balance between raw polymer viscosity and mixed compound viscosity when compounded with silica and/or carbon black and cured compositions are useful in tire tread having highly balanced wet traction, rolling resistance, and traction in ice and snow. The polymers can be utilized to form elastomer compositions for tire treads having balanced properties of reduced rolling resistance and wet traction and handling or balanced properties of wet traction and handling and traction in snow and ice.

Inventor: KITTAKA TOSHIHARU
IPC: C23C2/06
Filed: 1997-12-12
Abstract: A steel sheet having on the surface thereof a coating layer which is formed by hot dipping and which consists of 4.0 to 10 wt.% of Al, 1.0 to 4.0 wt.% of Mg and the balance consisting of Zn and unavoidable impurities, the coating layer having a metallic structure in which a proeutectic Al phase or both of a proeutectic Al phase and a single Zn phase are dispersed in a matrix of an Al/Zn/Zn2 Mg ternary eutectic structure. The coating layer having such a metallic structure can be formed by properly controlling the rate of cooling the coating layer adhering to the steel strip pulled up from a plating bath in continuous plating equipment and the temperature of the plating bath and/or by adding proper amounts of Ti and B into the plating bath. The streaking inherent in such a coated steel sheets is inhibited by controlling the configuration of a magnesium-containing film generated until the solidification of the coating layer or by the addition of a proper amount of Be into the plating bath.

Title: Improved process for saturated oligomer production
Inventor: FRAME ROBERT R
IPC: B01J27/16
Filed: 1998-09-21
Abstract: A process for the production of saturated oligomers by the oligomerization of light olefins to heavier olefins and the saturation of the heavy olefins is improved by the recycle of the heavy paraffins to the oligomerization zone. The recycle of the heavy paraffins improves the selectivity of the oligomerization for C g paraffin products and reduces catalyst fouling. The reduced catalyst fouling can be used to operate the oligomerization zone at lower pressure and facilitate its integration with a dehydrogenation zone for the production of the light olefin stream.

Inventor: CATHEY JOE RAY
IPC: E01D19/06
Filed: 1998-11-03
Abstract: A method to produce an expansion joint for adjacent roadway slabs having an expansion gap therebetween. A recess is cut or formed into the surface of each adjacent roadway slab to create a pair of recesses parallel to and adjacent the expansion gap. The recesses are cleaned to a sound, dust-free and rust-free surface. A temporary form is inserted in the expansion gap between the adjacent roadway slabs. A mortar mixture of a slightly resilient polymer and aggregate is installed in each recess to form a pair of parallel nosings adjacent the expansion gap.  High-strength filler blocks are encapsulated within the mortar mixture to reduce the volume of the mortar mixture and to thereby reduce the cost of the nosings. A temporary backing is inserted in the expansion gap between the nosings. An initially liquid sealant is installed between the nosings and on top of the temporary backing which will cure to form a flexible seal.

Inventor: BLANCO MARCOS ARES
IPC: H04L29/06
Filed: 1998-12-16
Abstract: Network bandwidth is controlled by dynamically determining a current window size for a destination buffer. A first window size is determined for the destination buffer at a first time. Then a current window size is determined a second time as a function of the first window size, a desired bandwidth value and a bandwidth used between the first time and the second time. A desired bandwidth for a particular connection is achieved by an adaptive, or delta-based approach rather than by round trip time computations. Bandwidth control can be achieved by a software or a hardware bandwidth control mechanism.  Possible applications of the bandwidth control is in a server or a quality of service unit.

Abstract: Ce nouveau produit consiste en un lambris relativement mince, léger, révolutionnaire et économique pouvant être utilisé autant dans la construction ou la rénovation de bâtiments commerciaux, industriels, utilitaires (cabanons et autres) et résidentiels. Ce revêtement extérieur affiche un style architectural comparable à celui que construisaient les premiers colonisateurs de notre pays et ce sans les inconvénients de pièces de bois massives équarrit, de dimensions et poids considérables, ayant des effets directs sur les coûts des matériaux de bases, d'énormes frais de main d'oeuvre, équipement, outils spécialisés et de manutentions, sans parler de la valeur thermique plus que médiocre de ce genre de bâtiment. Ces facteurs, ainsi que l'implication de techniques de construction peu communes, rendent l'accessibilité et l'intérêt de ce type de bâtiment, auprès des bricoleurs moyens et même des entrepreneurs expérimentés, à un niveau négligeable comparativement au marché des bâtiments de constructions plus conventionnelles et plus modernes.
