Title: Hose levelling device with electrical level indication - uses pressure detector arrangement for easy operation and error elimination (OE 15.5.77)
Inventor: WITTMANN FRANZ
IPC: G01C5/04
Filed: 1977-09-06
Abstract: A hose leveller with an electrical levelling indicator is designed for use with two fluid containers (1) connected by a hose. The device avoids operator errors and difficulties associated with visual comparison methods, partic. where determination of height difference is required. It also eliminates the complicated setting up of contact probe balancers which also have a tendency to lose fluid during use. Both containers are hermetically sealed press chambers with an associated pressure detector. The containers and the connecting hose are completely filed with fluid. When the containers are at the same height the press indicators give the same output signal. A height difference produces a corresp. signal difference. The signals are evaluated and compared in an electronic measurement and amplifier circuit connected to an electrical indicator.

Title: Solar energy system for whole world - has artificial planets reflecting radiation to earth which would otherwise by=pass it
Inventor: WEBER ERNST ING GRAD
IPC: H01L31/04
Filed: 1979-09-13
Abstract: A large number of artificial satellites are projected into orbit round the sun in paths similar to those of planets. Each satellite carries a reflector for solar radiation energy. They collect radiation which is not directed towards the earth and reflect it to earth. In this way the earth receives more energy than it does by natural direct radiation and sufficient energy to satisfy all its needs. A ring of receiving stations is built round the earth. As the earth rotates about its own axis each satellite sends energy to successive receiving stations and each station receives energy from successive satellites.
