Title: Dna molecule encoding for cellular uptake of mycobacterium tuberculosis
Inventor: RILEY LEE W
IPC: G01N33/569
Filed: 1994-09-01
Abstract: The present invention relates to a DNA molecule conferring on Mycobacterium tuberculosis an ability to enter mammalian cells and to survive within macrophages. The protein encoded by this gene fragment is useful in vaccines to prevent infection by Mycobacterium tuberculosis, while the antibodies raised against this protein can be employed in passively immunizing those already infected by the organism. Both these proteins and antibodies may be utilized in diagnostic assays to detect Mycobacterium tuberculosis in tissue or bodily fluids. The protein of the present invention can be associated with various other therapeutic materials, for administration to mammals, particularly humans, to achieve uptake of those materials by such cells.

Patent CA-2182961-A1 (CA)
Inventor: BRYAN-BROWN GUY PETER
IPC: G02F1/1337
Filed: 1995-01-30
Abstract: La présente invention concerne d'une part un dispositif à cristaux liquides ferroélectriques constitué d'une couche de cristaux liquides en substance ferroélectrique, maintenue entre les deux parois porte-électrodes des cellules et d'autre part un traitement d'orientation en surface. L'orientation en surface est assuré par profilage, par exemple par réseaux de diffraction sur l'une au moins des parois de la cellule. La structure du réseau de diffraction peut être simple ou double, à profil symétrique ou asymétrique. Une telle structure de réseau de diffraction permet de traiter de façon indépendante l'inclinaison de surface et l'énergie de stabilisation d'orientation convenant tant à la substance du cristal liquide qu'au type d'appareil. Cela permet d'obtenir l'organisation moléculaire attendue et une défectuosité propre à l'appareil aussi basse que possible. Pour réaliser ces réseaux de diffraction, on utilise un procédé interférographique, photolithographique, de nervurage, de traçage de lignes ou de transfert de couche support. Les orientations au niveau des parois des cellules peuvent être parallèles ou non parallèles. L'angle d'inclinaison de surface des deux parois peut être identique ou différent. Les parois des cellules, peuvent être relativement rigides, comme par exemple des lamelles de verre, ou flexibles, comme par exemple un plastique fin dont la face interne forme par nervurage, un réseau de diffraction, un ensemble de pions d'écartement, ou les deux à la fois.

Filed: 1996-09-18
Abstract: An air heating and humidifying system and method using direct contact heating principles. The system consists in providing a source of hot water by feeding hot flue gases in a direct contact water heater and wherein the water sprayed over a packing in the water heater is heated as it percolates through the packing and is in contact with the hot rising flue gases. This hot water from the direct contact water heater is used in a direct contact air treating chamber wherein it is sprayed over a further packing whereby to heat and humidify fresh air which is pushed through the packing by a fan and exits at an outlet flue of the treating chamber to supply hot moist fresh air in a building air conditioning system. The cooled water in the direct contact air treating chamber is collected and supplies the spray nozzle of the direct contact water heater to cool the hot flue gases which are rising therein and thereby enhances considerably the efficiency of the direct contact water heater.
