Title: Silicon-aluminium mixed oxide
Inventor: KERNER DIETER
IPC: C01F7/302
Filed: 2000-04-28
Abstract: A silicon-aluminium mixed oxide produced by flame hydrolysis and having a composition of from 1 to 99.999 wt.% Al2O3, the remainder being SiO2. The mixed oxide exhibits an amorphous structure in the X-ray diffraction pattern and consists of intergrown primary particles. In these primary particles crystallites are present; these crystallites having sizes of between one and 200 nanometres and the specific surface area of the powder being between 5 and 300 m2/g. The silicon-aluminium mixed oxide is produced by a process wherein silicon halide and aluminium halide are vaporised in a particular ratio to one another, and are homogeneously mixed with air, oxygen and hydrogen in a mixing unit by means of a carrier gas. This mixture undergoes combustion in a burner of known construction and, after the separation of the solids from the vapour phase, any traces of halide possibly adhering to the product are separated off in a further processing step by means of moist air at elevated temperature.

Title: Virtual retinal display with eye tracking
Inventor: JOHNSTON RICHARD S
IPC: G02B27/00
Filed: 1999-01-13
Abstract: Light emitted from a virtual retinal display (10) light source (12) passes through a beamsplitter (42) to a scanning subsystem (16) and on to an eyepiece (20) and the viewer's eye. Some of the light is reflected from the viewer's eye passing back along the same path. Such light however is deflected at the beamsplitter toward a photodetector (44). The reflected light is detected and correlated to the display scanner's position. The content of the reflected light and the scanner position for such sample is used to generate a map of the viewer's retina. Such map includes "landmarks" such as the viewer's optic nerve, fovea, and blood vessels. The map of the viewer's retina is stored and used for purposes of viewer identification. The viewer's fovea position is monitored to track where the viewer is looking.

Filed: 1998-12-10
Abstract: L'invention concerne un vaccin contenant des bactéries atténuées par une mutation non réverse dans un gène codant pour une protéine qui favorise le repliement de protéines extracytoplasmiques. Ces mutations, identifiées à l'origine comme pouvant servir de vaccins à partir d'une banque de mutants de transposon insérés de manière aléatoire, dans lesquels on a pu définir une atténuation sous la forme d'une baisse de la virulence de l'organisme du modèle murin de l'infection. Toute mutation ciblée de ce gène permet d'obtenir une souche présentant au moins 4 logs d'atténuation, une fois cette souche administrée à la fois par voie orale et intraveineuse. Les animaux vaccinés au moyen de cette souche sont protégés contre toute attaque ultérieure contre la souche parente de phénotype sauvage. Les antigènes hétérologues, par exemple le domaine de liaison non toxique et protecteur provenant du fragment C de la toxine tétanique, peuvent être administrés par l'intermédiaire du système immunitaire propre aux muqueuses, au moyen des souches bactériennes susmentionnées. On induit ainsi une réponse immunitaire protectrice contre toute attaque ultérieure contre la toxine tétanique native.

Filed: 2000-09-26
Abstract: The cooking oil spray dispenser has a container for receiving the cooking oil. A spraying mechanism is mounted on the upper end of the contain er for picking up and spraying the cooking oil. The spraying mechanism includes a tube through which the cooking oil is picked up from the container. This tube extends within the container and has an open lower end to which is fixed a filtering device having a central hub and a base with rim. The central hub i s shaped to fit onto the lower end of the tube while the base acts as a suppor t for a mesh which is supported by the rim of the base. In use, the mesh prevents clogging of the lower end of the tube with solid materials such as spices or herbs that may be contained in the cooking oil. Preferably, the mesh is a micromesh and has a convex shape. Such further reduces the risk of clogging since the herbs or spices cannot attach to the micromesh and thus cannot clo se the inlet of the tube.

Title: Pressure swing adsorption gas separation method, using adsorbents with high intrinsic diffusivity and low pressure ratios
Inventor: ACKLEY MARK WILLIAM
IPC: B01D53/047
Filed: 1999-02-26
Abstract: A gas separation process incorporating the invention combines use of an adsorbent having high intrinsic diffusivity with a low pressure ratio PSA cycle. Further enhancements to the process are derived from the use of fast cycles, shallow beds and small particles - especially in a radial bed configuration. The combination of low pressure ratio, high rate adsorbents and fast cycles has been found to result in an unexpected simultaneous reduction in bed size factor (BSF) and power consumption. These benefits have been achieved while minimizing a decline. in product recovery through use of the high rate adsorbent. The net result is a significant reduction in product cost.
