Abstract: A dry method of concrete floor or concrete surface restoration uses the process of grinding a concrete surface to be resurfaced while extracting and retaining dust during the grinding process. The grinding process is repeated each time using finer grinding grit until a preselected degree of smoothness of the concrete surface is achieved. A sealer is applied to the concrete surface which has been ground to the predetermined degree of smoothness. In a preferred embodiment, two coats of sealer are applied andthe sealer is preferably a water-based, odorless, penetrating alkaline siliconate solution.  The method of the present invention limits down time to aisles and main areas during the restoration process, as well as limiting the dust and odor during the process to provide a lustrous smooth surface on the concrete.

Inventor: TSUSHIMA MINEO
IPC: G10L19/093
Filed: 2003-07-30
Granted: 2012-02-21
Abstract: A wideband, high quality audio signal is decoded with few calculations at a low bitrate. Unwanted spectrum components accompanying sinusoidal signal injection by a synthesis subband filter built with real-value operations are suppressed by inserting a suppression signal to subbands adjacent to the subband to which the sine wave is injected. This makes it possible to inject a desired sinusoid with few calculations.

Title: Methods of increasing flotation rate
Inventor: YOON ROE-HOAN
IPC: C02F11/147
Filed: 2001-11-25
Granted: 2011-08-02
Abstract: Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicity-enhancing reagents include low HLB surfactants, naturally occuring lipids, modified lipids, and hydrophobic polymers. These methods can greatly increase the rate of flotation for the particles that are usually difficult to float, such as ultrafine particles, coarse particles, middlings, and the particles that do not readily float in the water containing large amounts of ions derived from the particles. In addition, new collectos for the flotation of phosphate minerals are disclosed.

Abstract: Cette invention se rapporte à un outil servant à la fabrication de clous à tête désaxée, un tel clou comprenant une tige et une tête, dont le centre est désaxé par rapport au centre de la tige. Cet outil fait partie d'un ensemble d'au moins deux outils agissant conjointement sur une ébauche de clou. Cet outil comprend un côté avant pourvu d'une ouverture réceptrice et un côté supérieur à utiliser lors de la formation de la tête. Cette ouverture réceptrice a une forme conçue pour produire une impression dans l'ébauche et pour fixer l'ébauche pendant la formation de la tête sur l'ébauche. Cette invention concerne en outre l'utilisation de cet outil. De tels clous avec têtes désaxées sont utilisés dans des cloueuses automatiques, dans lesquelles une bande de clous est utilisée pour des éjections multiples de clous, avant le rechargement de la cloueuse avec une nouvelle bande de clous. Les aspects nouveaux et inventifs de cet outil selon cette invention consistent en ce que l'ouverture réceptrice comporte une section saillante près du côté supérieur destinée à former dans la tige du clou une impression, placée adjacente à la tête et essentiellement à un côté, qui est opposé à la direction dans laquelle la tête est désaxée, et en ce que cette section saillante comporte au moins une surface essentiellement plate ou convexe destinée à former au moins une section essentiellement plate ou concave sur le clou, cette section plate ou convexe étant située essentiellement parallèle à l'axe longitudinal de l'ouverture réceptrice. Ainsi, on confère au clou une grande résistance dans la zone de transition entre la tige et la tête.

Abstract: L'invention concerne la mise au point d'un système de production et d'un système de transformation génétique de dihaploïdes, efficaces et économiques, permettant d'obtenir le déclenchement de la reproduction et la modification génétique de dihaploïdes chez le lin, respectivement. La culture préalable d'anthères sur un substrat renfermant de grandes concentrations de sel minéral et d'auxine, hautement osmotique, pendant un laps de temps donné, avant leur transfert vers un substrat renfermant de faibles concentrations de sel et d'auxine, faiblement osmotique, permet d'augmenter sensiblement l'efficacité globale de la régénération et l'efficacité des anthères par rapport à une mise en culture directe des anthères sur un substrat renfermant de faibles concentrations de sel et d'auxine, faiblement osmotique. Ce processus de culture permet également de réduire sensiblement la fréquence de régénération des pousses à partir de cellules somatiques dans la culture d'anthères. Ce processus a permis de mettre au point un système de transformation par cal obtenu par culture d'anthères hautement efficace. L'efficacité de transformation du système de transformation par cal obtenu par culture d'anthères est quatre fois supérieure aux meilleurs résultats de transformation obtenus à l'aide d'hypocotyles comme explants dans le système de transformation par Agrobacterium tumefaciens ou le système de transformations par bombardement de particules. La fréquence d'échappement dans le système de transformation par cal obtenu par culture d'anthères correspondait à un tiers de celle du système de transformation par hypocotyles à l'aide de A. tumefaciens ou à la moitié par bombardement de particules. Ce système de transformation hautement efficace est destiné à la recherche de base pour la découverte de gènes et à des applications pratiques du génie génétique pour des caractères améliorés.

Abstract: A method to provide to a sender (20) of RTP packets the actual receiver (50) buffer (54) fullness level in a receiver of the RTP packets at a certain time instant represented as remaining playout duration in time. The receiver sends in an RTCP report (26) the sequence number of a selected RTP packet in the receiver buffer and the time difference between the scheduled playout time of this packet and the current time. Based on this timing information, the sender calculates the amount of time it would take for the receiver buffer to empty if the receiver continues to playout at normal speed and no further RTP  packets arrive to the receiver buffer. This receiver buffer fullness level information can be used at the sender to adjust the transmission rate and/or nominal playout rate of the RTP packets in order to maintain a targeted receiver buffer fullness level.

Abstract: A software driven monitoring system includes a common control element coupled to a plurality of monitoring devices. The devices can indicate to the control element that a predetermined condition has been detected. Where the control element transmits a status inquiry command to the devices, those devices exhibiting the status provide the same indication to the control element as is indicative of the predetermined condition. One indication is a shunt or a short circuit of a medium between the common control element and the devices. An existing system can be upgraded by installing the control element, or upgrading an existing control program. Alternately, the devices can be installed in a system wherein the control element does not issue the status inquiry command. In those installations, the monitoring devices never issue a status reply as the required command is never received.
