Abstract: F(ab) fragments are isolated from an antibody containing source by contacting the antibody containing source with a papain-polyacrylamide matrix to produce F(ab) and F(c) fragments which are then passed through an antigen-polyacrylamide gel capable of attracting the F(ab) fragments. F(ab)2 fragments are obtained by contacting the antibody containing source with a pepsin-polyacrylamide matrix to produce F(ab)2 and F(c) fragments which are then passed through an antigen-polyacrylamide gel capable of attracting the F(ab)2 fragments. IgG antibodies are obtained by passing an antibody containing source through an antigen-polyacrylamide gel. These processes can be used to purify a wide variety of antibodies which can be used as therapeutic agents and as diagnostic agents. Antivenins produced by these processes have substantially reduced foreign protein levels and hence are less likely to produce immunogenic reactions.

F(ab).sub.2 fragments are obtained by contacting the antibody containing source with a pepsin-polyacrylamide matrix to produce F(ab).sub.2 and F(c) fragments which are then passed through an antigen-polyacrylamide gel capable of attracting the F(ab).sub.2 fragments.

Abstract: The terrain objects within the data base for an aircraft flight simulation system are formed by polygon faces and include certain objects formed by repetitive patterns of equally spaced identical polygon faces. More specifically, objects such as runway markings, which are a series of elongated narrow rectangles equally spaced along the length of the runway. The image data is arranged in a particular format including instruction words for identifying the type of data in the data words following each instruction word, and for controlling the flow of data through the image processor. The image data formatted and processed includes:Initialization vectors (Vo), defining the position of landmark points (i.e., the first vertex of the initial polygon of each series of faces).Delta data (shape data), defining the position of other points, (i.e., the remaining vertices of each initial face) with respect to the initial point therefor.

Abstract: The visual system within an aircraft flight simulation system receives flight data from a flight simulation computer, and terrain data from a gaming area data base. A computer within the visual system organizes this image data in a buffer memory according to a particular format, and forwards the image data to an image processor. The following types of data are formatted and processed:Position vectors, defining the changing position of the aircraft with respect to the origin of the terrain coordinate system.Rotational data, defining the changing attitude of the aircraft with respect to the terrain coordinate system.Initialization vectors, defining the position of the landmark points within the terrain coordinate system. The landmark points are translated into the aircraft coordinate system to form translated vectors.Delta data, defining the position of other points, lines, and faces with respect to the landmark points.CIF data, defining color, intensity, defocus, etc.
