Abstract: A heat exchanger is provided in an air duct between an air heater and a windbox of a combustion means such as a boiler. Dilution air is carried to the heat exchanger from a dilution sir fan in a separate duct. The heat in the, air from the air heater is transferred to the dilution air via the heat exchanger and the heated dilution air is sent to vaporize ammonia before the ammonia is introduced into an exhaust duct with a selective catalytic reduction (SCR) chamber. A bypass valve is provided around the heat exchanger for blending heated and unheated air to control the temperature of the dilution air.

Abstract: L'invention concerne une méthode de fragmentation d'un ADN bicaténaire utilisable dans une analyse d'acide nucléique, notamment dans une analyse multiplexée de polymorphismes et de mutations. La méthode produit de multiples fragments sens et antisens marqués, qui ne sont pas complémentaires, et ne subissent donc pas une recircularisation considérable dans des conditions appropriées pour une analyse d'hybridation (ou une analyse d'un allongement induit par capture) des polymorphismes et/ou mutations. Les fragments présentent une distribution désirée ou prédite de la longueur. Des sites de restriction peuvent être choisis de sorte que les fragments soient courts, mais en même temps suffisamment longs pour permettre une discrimination des fragments dans un dosage; et comme sujet de probabilité statistique, de sorte que la majorité des fragments contienne au moins un nucléotide marqué pour faciliter la détection.

Patent CA-2547957-C (CA)
Title: Method and roll stand for multiply influencing profiles
Inventor: KNEPPE GUENTER
IPC: B21B13/02
Filed: 2004-11-22
Granted: 2011-01-11
Abstract: When rolling sheets or strips in roll stands using working rolls, which are supported on back-up rolls or on intermediate rolls having back-up rolls, whereby the setting of the roll gap is effected by axially displacing roll pairs provided with curved contours, differences from the required profile occur in the instance of larger widths of a product range due to excessive extensions in the edge areas or in the quarter areas that are manifested in the form of so-called quarter waves in the flatness of the product. In order to rectify this problem by using a simple mechanism and to improve the setting mechanism and the strategy for creating absolutely planar strips with a predetermined thickness profile over the entire width of the rolling stock, the invention provides that for forming the roll gap set profiles (10, 11) for two selected displacing positions, the contours of the rolls of one roll pair are shaped in such a manner that they produce, in the roll gap, a profile (20, 21), which is symmetric with regard to the center of the roll and which has a profile maximum in the center of the roll that can be altered by displacing the rolls, whereas the contours of the rolls of at least one second roll pair produce, in the roll gap, a profile (22, 23), which is symmetric with regard to the center of the roll and which has two identical maxima outside of the center of the roll that can be altered by displacing the rolls.

Abstract: An aircraft comprising a wing defining an aerofoil surface, the wing comprising a deformable drooped leading edge flap being moveable between a stowed position and a deployed position and arranged such that during flight when the high-lift device is in the deployed position, air may flow through an opening in the wing and over the aerofoil surface.  The opening varies depending on the magnitude and direction.of the net aerodynamic force on the deformable drooped leading' edge flap that lifts the trailing edge of the deformable drooped leading edge off the adjacent portion of the wing when the deformable drooped leading edge flap is in its deployed position. During flight, air preferably flows into the boundary layer on the upper surface of the wing, energizing the boundary layer, aft of the trailing edge of the deformable drooped leading edge flap increasing its stability allowing the maximum achievable lift coefficient to be increased, thus reducing aircraft take-off and approach speeds.

Abstract: A method and system for scanning a TDMA channel by a subscriber unit in a wireless communications landscape 100 is disclosed. The subscriber unit locks onto a channel that is preprogrammed in the subscriber unit. A base radio transmits a control message to the subscriber unit. The control message informs the subscriber unit of activity present on the channel. The subscriber unit receives and decodes the control message to determine whether there is activity on the channel. If there is, the subscriber unit determines whether the activity is of interest. If it is, then the subscriber unit remains on the channel to receive the activity present on the channel.

The method comprising the steps ofincorporating a bore into the first component; welding the supporting plate to the first component; and joining the first component and the second component by incorporating a joining means arranged on the second component into the connecting means. Due to welding of the supporting plate to the first component, a rivet joint, otherwise generally required for joining the supporting plate to the first component , can be omitted, whereby the production of a junction by means of the inventive joining means is considerably simplified. Moreover, weakening of the first component as well as formation of corrosion processes due to different materials used for riveting being adjacent can be avoided. In addition, the invention relates to a joining element for creating a junction in accordance with the method. Furthermore, the invention relates to a device, in particular for performing the method.
