Title: HV generator for TV receiver CRT - has diode-capacitor voltage multiplier with intermediate voltage tapping, varying more than full HV
Inventor: BERGMANN GUSTL DIPL ING
IPC: H01J29/98
Filed: 1977-05-28

Title: Spherical omnidirectional windmill rotor - has curved blades operating with scoop action, twisted at base for upwards air flow for lift
Inventor: LANGE HEINZ
IPC: F03D3/06
Filed: 1978-02-06
Abstract: An omnidirectional windmill rotor is formed of a number (preferably seven) identical blades arranged symmetrically around a vertical shaft to which their upper and lower ends are secured. The blades are bowed outwardly at their wider central portions to define a sphere-like 'chamber' each blade having a curved trailing edge projecting outwardly beyond the leading edge of the adjacent blade in order to form a 'scoop' to receive the wind and induce rotation of the shaft. The lower end of each blade is twisted to form a deflecting portion on which the wind impinges to generate an upward movement of air within the chamber, serving to lighten the weight of the rotor on its bearing. A further projecting secondary blade can be secured to each main blade to enhance the scoop effect and to provide a gap between the main and secondary blades.

Title: Delay network pulse modulator for magnetron radar transmitter - has resonance charging and controlled switching circuits parallel to charging choke
Inventor: FRANKE HANS-JOACHIM
IPC: G01S7/282
Filed: 1978-02-28
Abstract: The delay-network pulse modulator's control circuit controls the switching device in accordance with the desired magnetron pulse current. This guarantees a "soft" starting-up. When the modulator is switched on, the magnetron pulse current first reaches only a given fraction, e.g. half, of the final value occurring in "run-in" transmission operation during the initial pulse periods. During the subsequent pulse periods the magnetron pulse current rises successively to the final value within a given time interval.
