Abstract: A method for repairing a basecoat/clearcoat finish or coating comprised of a fluorinated organosilane topcoat. A fluorinated urethane additive is added to the fluorinated organosilane topcoat composition to improve recoat adhesion with the repair basecoat.

Abstract: In the present invention, viruses, plasmids or both are constructed which contain viral DNA and lox sites positioned such that site-specific recombination between lox sites in separate plasmids results in generation of infectious viral DNA at high-efficiency in cotransfected host cells that have been engineered to express the Cre recombinase. Because of the high-efficiency and specificity of the Cre enzyme, suitably engineered plasmids can be readily recombined to produce infectious virus at high-efficiency in cotransfected 293 cells, without, at the same time, producing wild-type adenovirus, with the attendant problems for removal thereof. Use of recombinases besides Cre and recombinase recognition sites besides lox sites, and use of cells other than 293 cells are also disclosed and enabled, as are kits incorporating the site-specific vector system.

Abstract: The present invention relates to methods for efficient and reliable construction of adenovirus vectors which contain and express foreign DNA and are useful for gene transfer into mammalian cells, for vaccines and for gene therapy. The invention provides for the growth and purification of adenovirus vectors (helper dependent vectors or HDVs) from which all or most of the viral genes have been removed. The vector system described herein is a new method designed to eliminate helper viruses from the final HDV preparation by cleavage of the helper virus DNA with an endonuclease, alone or in combination with other methods known to limit the level of helper virus contamination of helper dependent vector preparations. The disclosed methods and compositions also provide for regulated control of gene expression.

Abstract: Embodiments of the invention provide cells that stably express an integrase family recombinase, for example Cre or FLP. Examples of production of such cells, and uses of such cells, are provided. In some embodiments, a cell may additionally express one or more adenovirus E1 proteins. In some embodiments, the cell is an in vitro human cell.

Abstract: Methods, cells and recombinant adenoviral vectors are disclosed that permit the production of recombinant adenoviral vector stocks with reduced levels of contamination by replication competent adenoviruses (RCA). In certain embodiments are disclosed early region 1 (E1) deficient recombinant adenoviral vectors and complementing E1 positive host cells whose sequences are designed to avoid formation of RCA by homologous recombination between sequences in the vector and E1 sequences in the cells. One aspect of the invention involves the inversion of the packaging signal in a recombinant adenoviral vector relative to an adjacent or nearby inverted terminal repeat (ITR). Methods include use of site-specific intregrase family recombinases such as Cre or FLP and recombinase recognition sites such as lox sites or frt sites.

Abstract: This invention provides helper-dependent adenovirus cloning vectors and helper adenoviruses, and methods for making and Using such preparations, wherein the helper adenoviruses contain recombinase target sites that are useful in reducing the level of contamination of helper virus in helper-dependent adenovirus vector preparations.

Abstract: A centralized test apparatus is provided for a telecommunications network which includes local switches and a core network. Each local switch is connected through terminating lines to terminating equipment such as telephone handsets. The test apparatus enables a field engineer to obtain the identity of a terminating line from one of the local switches. When a field engineer dials the number of the test apparatus, the test apparatus retrieves the calling line identity on answering the call. It then transmits the calling line identity in speech form back to the calling line. After transmitting the calling line identity, the test apparatus offers a menu of further services which comprise a ring back service and the provision of a test tone on a specified telephone line.

Abstract: A method and apparatus for treating a load with dyeliquor includes a pump/motor set, a dyeliquor circulating system holding the load and directing all the dyeliquor pumped by the pump to flow through the load, a motor current measurement device to measure current consumed by the electric motor while driving the pump, and a throttle valve adjusted to create a flowrate of the dyeliquor through the dyeliquor circulating system based on the current measured by the motor current measurement device. The flowrate of the dyeliquor increases linearly in proportion with increases in the current consumed by said electric motor while driving said pump. The apparatus also has a low system resistance to fluid flow allowing variations in a load resistance of the load to fluid flow to produce corresponding variations in the current of the electric motor measurable by the motor current measurement device.
