| 20110098121 | BALL COUPLING DEVICE WITH HINGED CONNECTION FOR TWO SLIDING SHAFTS - The invention relates to a device for coupling an inner shaft and an outer shaft sliding in the direction of a common axis thereof, with balls provided between the two shafts. The balls are arranged in axial grooves of the inner shaft and in axial grooves of the outer shaft. Each row of balls is maintained by a double elastic member that bears in the groove of the inner shaft and urges the balls along two rolling tracks so that they come into contact with the groove of the outer shaft, wherein each of the two rolling tracks is hinged through a pivot surface and a bearing surface of the corresponding shaft, and the difference between the radii defines two bearing areas defining a hinge axis parallel to the common axis. | 04-28-2011 |

| 20100154725 | IMMEDIATE RESPONSE STEAM GENERATING SYSTEM AND METHOD - The method of generating immediate and thereafter continuous steam is used in a steam generating system comprising a steam accumulator, a steam outlet connected to the steam accumulator, an outlet valve at the steam outlet, and a quick response steam generator unit connected to the steam accumulator. The method comprises the steps of providing latent steam in the steam accumulator, opening the outlet valve to allow latent steam in the steam accumulator to exit through the steam outlet, feeding water to the steam generator unit, heating the water fed to the steam generator unit while the latent steam exits through the steam outlet and, before the latent steam has entirely exited the steam accumulator, generating steam with the steam generator unit to feed the steam accumulator and controlling the steam flow rate through the steam outlet to maintain it at a value which is essentially not greater than the steam flow rate from the steam generator unit to the steam accumulator. The steam generating system is capable of generating immediate and thereafter continuous steam from an initial steam generator unit cold condition due to the steam accumulator providing steam at the steam outlet while the steam generator unit heats the water fed therein. | 06-24-2010 |

| 20090203648 | Modified phosphocalcic compound, injectable composition containing same - A phosphocalcic compound modified by a gem-bisphosphonic acid or one of its salts, a method for preparing same, as well as its use for preparing an injectable composition. The modified phosphocalcic compound is obtained by adding a gem-bisphosphonic acid or one of its alkali metal or alkaline earth salts to a suspension of a precursor phosphocalcic compound in ultras-pure water, while stirring the reaction medium at room temperature, then in recovering by centrifuging the formed compound. The compound is useful for making an injectable composition, for use in the treatment of bone remodeling equilibrium. | 08-13-2009 |
| 20100197636 | INJECTABLE CALCIUM-PHOSPHATE CEMENT RELEASING A BONE RESORPTION INHIBITOR - The present invention relates to a macroporous, resorbable and injectable apatitic calcium-phosphate cement with a high compressive strength useful as bone cement and releasing a bone resorption inhibitor, preparation method and uses thereof. | 08-05-2010 |
| 20100248191 | Galliated calcium phosphate biomaterials - The present invention relates to a galliated calcium-phosphate biomaterial comprising a gallium-doped phosphocalcic compound of formula (I): | 09-30-2010 |
| 20100269734 | Gallium-doped phosphocalcic compounds - The present invention relates to a gallium-doped phosphocalcic compound of formula (I): | 10-28-2010 |
| 20110142940 | Analgesic Apatitic Calcium-Phosphate Cement - The present invention concerns a composition useful as bone substitute comprising one or more calcium-phosphate compounds in association with an analgesic. It also refers to a preparation process of said composition, a preparation process of a drug-combined device comprising said composition, the drug combined device thus obtained, a kit comprising said composition and the use of said composition for the preparation of a drug-combined device useful for filling a bony defect caused in the iliac crest by collection of auto-graft bone, as a scaffold for tissue engineering and to produce a dental or bony implant. | 06-16-2011 |
