Title: DC power supply stabiliser with voltage divider or multiplier - uses coarse and fine stabiliser circuits connected in series on output side
Inventor: PLASSMANN WILFRIED DIPL ING
IPC: G05F1/62
Filed: 1979-04-30
Abstract: The proposed circuits operate on the established pulse width modulation principle. The purpose of the circuit modifications is to assist in eliminating errors due to amplifier offsets, internal circuit impedances, and common mode interference. The stabiliser is divided into two units connected in parallel to the uncontrolled d.c. mains supply. Both act as pulse width modulators, one gives a coarse stabilisation and the other a fine, trimming stabilisation. The output of both units is connected in series. The units are connected such that the feedback for the coarse regulator is its own output voltage, whilst the feedback for the fine regulator is the sum of coarse and fine regulator voltages, that is the total regulator output. The fine regulator acts to correct for faults, and to give the necessary resolution. Stabilisation to one part in 107 is claimed.

Title: Separator for parallel conductor overhead line - provides freedom of movement in two mutually perpendicular planes
Inventor: BRAND ROLF
IPC: H02G7/12
Filed: 1979-12-12
Abstract: The object of the separator is to damp out long wave-length mechanical oscillations in parallel conductors, especially in long spans between support towers. The separator comprises a clamp (1,2) at each end by which it is attached to the respective cables (22). Attached to each clamp by a pivot pin is a link (5,6) typically of flat bar with a 90 degree twist in it. Joining the two twisted links (5,6) are two straight links (3,4) in parallel. The joints between the sets of links are also pivot points. In this way a spacer with two planes of movement is produced. The separator functions satisfactorily with regard to spacing the conductors and damping long wave oscillations regardless of the relative position of the two conductors to one another in space. The separator prevents vibration of conductors caused by aerodynamic instability at high wind speeds, typically 8 to 20 meters per second, and when the conductors are covered with flat ice.
