Title: Secondary radar system with diversity transponder for aircraft - alters coding of response signal to designate radiating antenna
Inventor: BETZ ERICH ING GRAD
IPC: G01S7/42
Filed: 1977-09-27
Abstract: The radar system uses the response signal radiated by the antenna which exhibits the greatest reception level for the interrogation signal. The information relating to the antenna to be used for radiating the response signal is fed to the coder of the transponder, for coding the response signal in different ways each designating a particular antenna. The transponder has two reception paths coupled respectively to an upper and lower antenna and each incorporating a mixer and an IF amplifier. Both mixers are fed from a common oscillator. The output signals of both IF amplifiers are fed to a selection circuit determining which has the higher value to control a switch for sending the response signal to one or other antenna and providing a coding control input for the coder. The radar can be incorporated in aircraft.

Title: Optical flatness measurement using collimated light - integrates reflected light after direction changes caused by prismatic reflection
Inventor: DEBLER ERHARD DIPL ING
IPC: G01B11/30
Filed: 1978-01-27
Abstract: The optical method is for flatness measurement and involves the use of a measurement beam from a collimator or photoelectric autocollimator telescope tube for contactless measurement of deviations from flatness of an optically plane surface. A constant beam deflection angle is achieved by double reflection using mirrors and prisms, e.g. pentagonal prisms, and dispersion-free prisms through which the beam passes symmetrically. The measurement beam is incident perpendicular or inclined to sections of the surface and is "shifted along one or more crossed paths on the surface and received after reflection. Direction changes are derived and integrated. In one embodiment, the light emerges from a collimating tube (1) through an aperture stop(2) as a parallel beam (3) impinging on a pentagonal prism (4) with internal reflection and retro-reflection from the optical flat (5).
