Title: Combination of filter and electrostatic separator
Inventor: MILLER STANLEY JOHN
IPC: B03C3/80
Filed: 1998-08-21
Granted: 2003-03-25
Abstract: A device and method for controlling particulate air pollutants of the present invention combines filtration and electrostatic collection devices. The invention includes a chamber housing a plurality of rows of filter elements (24). Between each row of filter elements (24) is a grounded plate (26).  Between the grounded plates (26) and the filter elements (24) are electrode grids (28) for creating electrostatic precipitation zones between each row of filter elements (24). In this way, when the filter elements (24) are cleaned by pulsing air in a reverse direction, the dust removed from the bags will collect in the electrostatic precipitation zone rather than on adjacent filter elements (24).

Title: New fluxing agents
Inventor: SESEKE-KOYRO ULRICH
IPC: B23K1/19
Filed: 1999-03-23
Granted: 2011-05-17
Abstract: According to the invention components made of aluminium and aluminium alloys can be welded at temperatures of up to 600 ~C using a fluxing agent on the basis of alkali fluorozincate or alkali fluoride/zinc fluoride mixtures. Other fluxing agents, for example on the basis of potassium fluoroaluminate can be used in addition. Alkali fluorozincate fluxing agents, especially potassium and cesium fluorozincate fluxing agents, act not only as a fluxing agent but also improve the surface quality since zinc and alkali fluoroaluminates are deposited on the surface of the components. The invention also relates to new fluxing agents on the basis of alkali metal fluorozincates.

IPC: A61P35/00
Filed: 1999-12-03
Granted: 2012-04-10
Abstract: Stimulation of T cells to respond to self antigens is achieved through a blockade of CTLA-4 signaling. CTLA-4 blocking agents arc combined with antigen preparations, either alone or with additional immune response stimulating agents, in costimulation strategies to break immune tolerance and stimulate an enhanced T-cell response against self antigens. This enhanced response is useful for the treatment of non-immunogenic and poorly-immunogenic tumors, as well as other medical conditions requiring selective tissue ablation.

Abstract: A navigation controller and method for performing navigation control are provided. According to the method, a time varying prediction model is determined based on a predictor having a model component and a correlation processor component. The time varying linear prediction model is then used to formulate a predictive controller or to update the controller in use. The controller is then used to control navigation. Because of the correlation processor, the predictor is better adapted to compensate for shortcomings inthe model thus making the automated navigation control superior. In use, the method controls vessel navigation in any of a number of predefined modes such as cruising and turning modes. Moreover, through the selection of the operational scenario, the controller can be made to adapt to differing control objectives - for example tight tracking or increased operational efficiency of the vessel.

Abstract: A hot-fillable, slender, blow-molded plastic bottle (10, 110, 210) for use in containing hot-filled beverages. The bottle (10, 110, 210) has a sidewall (16, 116, 216) with various interactive zones of function. For example, some of the zones are primarily responsible for accommodating vacuum absorption, while other zones are primarily intended to rigidify the container (10, 110, 210) such as by providing post strength to improve container top loading capability. Although each zone may have a primary function, each zone also aids adjacent zones in providing their functions.   Thus, the entire sidewall (16, 116, 216), and not merely selected locations, reacts to the forces generated by the hot-fill process on the container (10, 110, 210).

Abstract: The present invention relates to a disposable dispensing apparatus for delivering a powdered product nasally or orally. The apparatus comprises a housing (1) defining an outlet (7) and a shaft (32) having a storage chamber (33) therein for a product provided with a first inlet (34) and a first outlet (35). A sheathing means (4) is slidably mounted on the shaft and has a second inlet (42) and a second outlet closed by a frangible membrane (44). There is also provided a variable volume means (2) operatively connected to the shaft.  The shaft is movable, on operation of the variable volume means to reduce the variable volume so as to pressurise gas in an interior of the variable volume means, from an initial storage position in which the first and second inlets are out of alignment so as to close a gas flow path, to a dispensing position in which the first and second inlets are brought into alignment by action of the housing against the sheathing means. At the same time, the frangible membrane is ruptured by the shaft so as to open the gas flow path, such that pressurized gas from the interior of the variable volume means is discharged along the gas flow path comprising the first and second inlets, storage chamber, second outlet and first outlet, to thereby entrain powdered product and dispense it through the housing outlet.
