Abstract: The VTOL aircraft includes a free wing having wings on opposite sides of the fuselage connected to one another for joint free rotation and for differential pitch settings under pilot, computer or remote control. On vertical launch, pitch, yaw and roll control is effected by the elevators, rudder and the differential pitch settings of the wings, respectively. At launch, the elevator pitches the fuselage nose downwardly to alter the thrust vector and provide horizontal speed to the aircraft whereby the free wing freely rotates relative to the fuselage into a generally horizontal orientation to provide lift during horizontal flight. Transition from horizontal to vertical flight is achieved by the reverse process and tile aircraft may be gently recovered in or on a resilient surface such as a net.

Abstract: The present invention relates to a method of generating antibodies directed against cell surface antigens and it uses recombinant insect cells as immunogens. The insect cells have been transfected with coding regions for a molecule containing a cell surface antigen and these antigens are expressed on the surface of the insect cells. Host animals are immunized with these transfected insect cells to generate antibodies directed against the cell surface antigen. Antibody-producing cells from the host animal are used to generate monoclonal antibody-producing hybridoma cells. Sera and hybridoma supernatants can be tested for the presence of antibodies against the surface antigen, using the transfected cells in a screening assay. Specific antibodies that have been generated by the present method are anti-B7 and anti-CD40 antibodies and they can be used to prevent or treat an antibody-mediated or immune system disease in a patient. The anti-B7 antibodies can be used to cause T cell anergy, treat allograft transplant rejection, treat graft versus host disease, and prevent or treat rheumatoid arthritis. An immunosuppressive agent may be co-administered with the antibody. The anti-CD40 antibodies which bind to the CD40 antigen can be used to prevent the growth or differentiation of the B cell. Monoclonal antibodies useful in these methods, and epitopes immunoreactive with such monoclonal antibodies are also presented.

Abstract: The invention relates to a method and a device (36) for controlling the operating point (AP1,AP2) of a series tuned-circuit invertor (6 to 14). According to the invention, the frequency (f) of the invertor (10) is controlled as the control variable as a function of a specific phase-angle control difference ( phi e) in such a manner that a detected actual phase angle value ( phi Z) of a state variable (Z, i, uc), which can be measured, of the load circuit (12,14) and whose phase response runs monotonally in a falling manner corresponds to a required phase angle value ( phi <*>) which can be predetermined. A method and a device (36) are thus obtained for controlling the operating point (AP1,AP2) of a series tuned-circuit invertor (6 to 14), by means of which the specified operating range (A) for the tuned-circuit invertor can be detected and stabilised irrespective of parameter fluctuations of the tuned-circuit elements.   <IMAGE>
