Abstract: La présente invention concerne un procédé dans lequel on utilise une émulsion inverse stable destinée à un fluide de forage à base d'huile qu'on associe à un additif sans danger pour l'environnement qui élimine efficacement l'hydratation du schiste argileux et l'érosion du trou de forage qui en résulte. L'additif est de préférence du formate de potassium, bien que d'autres formates ou acétates puissent le remplacer. Dans le procédé, le formate de potassium est dissous dans la phase aqueuse de l'émulsion à la place d'autres sels moins écologiques tels que le chlorure de sodium. L'activité de l'eau dans l'émulsion et dans la formation en cours de forage est surveillée pendant le forage de sorte qu'on puisse ajouter, si nécessaire, du formate supplémentaire pour maintenir à un niveau équilibré les activités de l'eau. C'est-à-dire que, de préférence, l'activité de l'eau du formate de potassium est égale ou inférieure à l'activité de l'eau de la formation.

Abstract: An improved and non-destructive test apparatus utilises ultrasound wave energy to automatically judge the sealing effectiveness of a sealed compartment (30) such as the cabin of a motor vehicle or aircraft. An ultrasonic transmitter (28) generates ultrasound energy of a specified frequency within the compartment (30), and one or more ultrasound sensors (20) outside the compartment (30) detect the presence and amplitude of ultrasound energy at the specified frequency. The detected energy level is compared to a calibrated threshold (84), and a leak indication is generated if the threshold is exceeded (42, 52). In a factory setting, the compartment (30) can be passed through an arched array of ultrasound sensors (18, 20) strategically located to detect the presence and amplitude of ultrasound energy of the specified frequency in the vicinity of potential leakage areas of the compartment (30). If the position of the compartment (30) relative to the sensor array is known, the leak indication can be used to pinpoint the location of the leak, and to suggest specific corrective action (52).

Title: Process for the fractionation of cereal brans
Inventor: KVIST STEN
IPC: A23L29/262
Filed: 2002-02-21
Granted: 2012-10-02
Abstract: A process for the fractionation of valuable fractions from cereal brans (e.g.  wheat, barley and oat brans, and rice polish) is described. In particular, this invention describes a two step process, in which the said bran is first subjected to a combination of enzymatic treatment and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main bran factions, i.e. insoluble phase (pericarp and aleurone layer), germ-rich fraction, residual endosperm fraction and soluble sugars. A  second step consists of fractionating cereal brans substantially free of soluble compounds, hence insoluble phase from the above-mentioned first step, by enzymatic treatment with xylanases and/or beta-glucanase and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main fractions, i.e. insoluble phase (remaining cell wall components), protein-rich fraction, soluble hemicellulose and oligosaccharide, and therefore maximizes the extraction rate of valuable cell wall components and aleurone cells from previously cleaned bran.

Title: Tissue collection device and methods
Inventor: BINETTE FRANCOIS
IPC: A61F2/46
Filed: 2004-03-29
Granted: 2011-10-18
Abstract: A biological tissue collection device is provided having a housing with a fluid-retaining inner chamber adapted to retain a bioimplantable, fluid permeable tissue scaffold. The scaffold is preferably retained in the housing in such a way that the scaffold separates the fluid-retaining inner chamber into a first chamber and a second chamber. The collection device further includes a driver mechanism coupled to the housing and effective to create a force within the housing to displace fluid disposed within the second chamber to the first chamber. As the fluid is displaced, any biological tissue deposited on the tissue scaffold is dispersed within the fluid. Removal of the force enables the fluid to return to the second chamber and thereby deposit the tissue onto the tissue scaffold. In an exemplary embodiment, the tissue is deposited evenly onto the tissue scaffold.
