Title: Cold-adapted equine influenza viruses
Inventor: DOWLING PATRICIA W
IPC: A61K39/145
Filed: 2001-02-16
Granted: 2012-08-28
Abstract: The present invention provides experimentally-generated cold-adapted equine influenza viruses, and reassortant influenza A viruses comprising at least one genome segment of such an equine influenza virus, wherein the equine influenza virus genome segment confers at least one identifying phenotype of the cold-adapted equine influenza virus, such as cold-adaptation, temperature sensitivity, dominant interference, or attenuation. Such viruses are formulated into therapeutic compositions to protect animals from diseases caused by influenza A viruses, and in particular, to protect horses from disease caused by equine inlfuenza virus. The present invention also includes methods to protect animals from diseases caused by influenza A virus utilizing the claimed therapeutic compositions. Such methods include using a therapeutic composition as a vaccine to generate a protective immune response in an animal prior to exposure to a virulent virus, and using a therapeutic composition as a treatment for an animal that has been recently infected with a virulent virus, or is likely to be subsequently exposed to virulent viruses in a few days whereby the therapeutic composition interferes with the growth of the virulent virus, even in the absence of immunity. The present invention also provides methods to produce cold-adapted equine influenza viruses, and reassortant influenza A viruses having at least one genome segment of an equine influenza virus generated by cold-adaptation.

Abstract: A cooking appliance employing rapid cook technology includes a controller which calculates rapid cook times from conventional cooking times input by a user. That is, for relatively long convection cooking cycles, such as a convection roasting mode, after a user enters a standard radiant cooking time into a control panel, an electronic controller subtracts a certain percentage, preferably 25%, off of the standard time to establish a rapid cook time. In one preferred embodiment, the rapid cook time is presented in a display and used as the actual cook time for the cooking operation. In another preferred embodiment, the standard cooking time is established for the cooking operation, but the user is signaled to check the food when the rapid cook time expires.

Abstract: A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a similar or different substance. Reverse roll coating may be used to coat the two surfaces of the sheet of laminate material. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing, other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate. The kraft sheet thus coated may be used to form a laminate panel that may be applied on an exterior wall, an interior wall, siding, a roof top, a facade boarding, a counter top, a tabletop or a work top.
