Abstract: Apparatus for escaping from a building through a window, comprises a plurality of rungs having first and second ends. A first side support is coupled to the first ends of the rungs. The first side support has an upper end. A second side support is coupled to the second ends of the rungs. The first side support has an upper end. A securement assembly is coupled to the wall of a building adjacent a window for providing egress. A first securement secures the upper end of the first side support to the securement member. A second securement secures the upper end of the second side support to the securement member. A plurality of first arms are each positioned proximate the first ends of a respective one of the rungs and are each moveably mounted to go from a retracted position to an extended position. A plurality of first arms are each positioned proximate the first ends of a respective one of the rungs and are each moveably mounted to go from a retracted position to an extended position.

Abstract: An improved safety ladder and safety window as well as a method for use are disclosed. The ladder is discrete and compact, for convenience. The ladder is stored in a hidden container that is an extension or an addition to a normal window, or made part of an existing window, for example by being housed in a box associated with the window. The inventive built-in safety ladder provides for an easy escape in the case of an emergency. The window may be employed in a double-hung window, casement window, awning, hopper, or any operating window which can be used for egress. The fire escape can be incorporated in wood, vinyl, aluminum, steel, and other types of windows. The box may also be used for housing other items such as emergency escape smoke hoods that are used as breathing apparatus, or as a hidden wall safe to store valuables and can be accessed using a security code.

Abstract: An improved extruded frame member window incorporating a fire escape or safety ladder as well as methods of manufacture are disclosed. The ladder is discrete and compact, for convenience. The ladder is stored in a hidden container that is an extension or an addition to a normal window, or made part of an existing window, for example by being housed in a containment structure associated with the window. The inventive built-in safety ladder provides for an easy escape in the case of an emergency. The window may be employed in a double-hung window, casement window, awning, slider, hopper, or any operating window which can be used for egress. The fire escape can be incorporated in wood, vinyl, aluminum, fiberglass, steel, and other types of windows. The box may also be used for housing other items such as emergency escape smoke hoods that are used as breathing apparatus, or as a hidden wall safe to store valuables and can be accessed using a security code or other secure access means.

Abstract: The invention relates to post-transfusional non-A non-B hepatitis viral polypeptide, DNA sequences encoding such viral polypeptide, expression vectors containing such DNA sequences, and hosts transformed by such expression vectors. The invention also relates to the use of such polypeptides in diagnostic assays and vaccine formulations.
