Abstract: A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formation zone, after the titania particles have formed. The process provides titania particles with a high rutile content and a smooth and homogeneous coating of a metal oxide.

Abstract: A pipette (1) includes a dispensing piece (3) and a separately formed and attached discrete bellows piece (5). The dispensing piece includes a dispensing end (7) through which liquid enters or leaves the interior of the dispensing portion and a connecting portion (9) which receives a corresponding connection portion (11) at the lower end of the bellows piece. The bellows piece (5) includes a bellows portion (13) having a plurality of circumferentially extending folds at intervals along the axis of the device. The bellows portion defines a closed end wall (17) against which an axial force may be applied to compress the bellows portion. The bellows portion (13) does not extend the entire length of the bellows piece (5). The pipette is arranged such that liquid may enter not only the dispensing piece but also the lower part of the bellows piece in use. The folds of the bellows piece are arranged to avoid liquid being trapped in the folds when the bellows piece is compressed axially.

Abstract: There are disclosed systems and methods for supporting cable redundancy in a network. In one embodiment, an adapter has a first port having a first IP  address and configured to join a multicast group and receive a first multicast message over a first transmission route. The adapter has a second port having a second IP address and configured to join the multicast group and receive a second multicast message over a second transmission route. The first and second messages both contain output data. The output data in the first message is directed to a data structure when the first transmission route is operational, and the output data in the second message is directed to the data structure when the first transmission route is non-operational and the second transmission route is operational. The IP address of the second port may be dynamically changed to the IP address of the first port.

Abstract: A method for constructing a velocity vector field from a grid and a set of fluxes for each face of the grid cells. The cells are first subdivided and internal fluxes are calculated for each cell subject to the constraints of the flux for each cell and to achieve the minimum energy state for the each cell. The minimum energy state is computed efficiently using a divergence-free correction method without introducing a pressure variable. Then, the velocity vector field is constructed from the subcell fluxes using mixed finite element interpolation.

Abstract: This invention provides stable aqueous compositions including stable coating compositions, and methods of their production. The stable aqueous compositions and stable aqueous coating compositions comprise one or more emulsion-polymerized addition polymer, one or more carboxylesterase enzyme, and one or more carboxylesterase deactivating agent, such that the ester hydrolysis activity in the composition is less than 0.010 micromole/minute, and wherein the aqueous composition has a headspace volatile organic compound (VOC) content, as measured by headspace gas chromatography-mass spectrometry (GC-MS) at 33°C, of less than 10 ppm of organic carboxylester with a normal boiling point of less than 150°C  and more than 50 ppm of mono-alcohol with a formula molecular weight of less than 76. The carboxylesterase enzyme is employed to minimize the free carboxylester content in the composition, thereby providing a low odor composition, and the carboxylesterase is deactivated in situ in order to minimize the residual carboxylesterase enzyme activity.

Title: System for decontaminating water and generating water vapor
Inventor: RILEY JOHN D
IPC: C02F1/04
Filed: 2009-06-23
Abstract: A system and method for decontaminating water and generating water vapor includes introducing contaminated water in to a vessel. The water is moved through a series of rotating trays alternately separated by stationary baffles so as to swirl and heat the water to effect the vaporization thereof to produce a vapor having at least some of the contaminants separated therefrom.  The vapor is removed from the vessel for condensing apart from the separated contaminants and the remaining water. The vapor may be passed through a turbine connected to an electric generator.  Sensors in a controller may be employed to adjust the speed of rotation of the trays or water input into the vessel in response to the sensed conditions. The treated water may be recirculated and reprocessed through the vessel to increase the purification thereof.

Abstract: A power solar panel is maintained in an optimum position relative to the sun during daylight as the sun traverses a solar track elevated above the horizon and extending from a sunrise location to a sunset location during each day of consecutive days of the year by utilizing solar energy to power a sun tracker which carries the power solar panel. The sun tracker includes pairs of solar modules wherein the solar modules are arrayed in an A-shaped cross-sectional configuration for being aimed directly at the sun in response to exposure to the sun, and the pairs of solar modules power motors which tilt the solar panel about a horizontal direction and rotate the power solar panel about a vertical direction to maintain optimum alignment with the sun during the course of a day.  Two of the pairs of solar modules are connected alternately to a motor that rotates the solar panel about the vertical direction and are mounted spaced apart in transverse directions, diametrically opposite one another with respect to the vertical direction, and for tilting about lateral directions to aim each of the two pairs toward the solar track such that a first one of the two pairs powers the motor during one day of consecutive days, and the second one of the two pairs powers the motor during a next-consecutive day, thereby compensating for daily changes in the solar track and providing power for effective operation during consecutive days throughout the year.

Abstract: A communication device and method for displaying messages, such as e-mail messages, is provided. When the message is lengthy, containing content from one or more replicated previous messages (such as earlier messages copied in a subsequent reply or forwarding message), the replicated previous messages are typically appended at the end of the message in reverse chronological order. The device identifies the replicated previous messages by delimiters included in the message, and displays the various delimited segments of the message in a reverse order so that the replicated previous messages can be read in the order in which they were transmitted, without requiring the user to read through the entire message from beginning to end. The device may automatically scroll through the content, or may page through the content in response to user commands.

Title: Mount for dental ceramic blocks
Inventor: MOORE PAUL
IPC: A61C19/00
Filed: 2009-10-01
Abstract: The present invention is directed to a dental mount for receiving and retaining a plurality of different dental ceramic blocks used in dental restoration treatments, wherein the dental mount comprises a substantially flat front face having a plurality of dental ceramic block receiving holes located thereon; each of the dental ceramic block receiving holes being dimensioned to form a retaining fit with any one of the different dental ceramic blocks. The advantage of providing a dental mount with dedicated holes for retaining any one of the dental ceramic blocks is that the dental mount can be used to comparatively present all the different types of dental ceramic blocks next to one another in an organised and graded manner so that a dentist may make quick and accurate comparisons between the different types of dental ceramic blocks. Furthermore, the dentist can quickly asses their stock levels by glancing at the dental mount. A further advantage is that the dental ceramic blocks are securely held apart from one another on the dental mount and therefore cannot damage one another when they are moved or transported.
