Title: Utilisation of solar energy with balloon mounted mirror - transmits energy to ground by balloon mooring cables
IPC: F24S20/20
Filed: 1975-02-11
Abstract: A solar energy collection system has a balloon with one half made of transparent material and the other half with a reflecting inner surface. The balloon is orientated so that the transparent half faces the sun and the rays are focussed onto an energy capturing device. The energy may be used to produce steam which drives a generator and the electrical energy is transmitted to the ground by the mooring cables. A device senses the direction of the sun and transmits a signal to a control system which controls the altitude of the balloon through the cords and pulleys. A free balloon may be used in which case the energy is used to produce hydrogen by the electrolysis of water.

Title: Driving motors for roller tables or electric traction vehicles - has circuit permitting use of normal three-phase motors
IPC: H02P27/02
Filed: 1975-04-07
Abstract: A drive arrangement, esp. for electric traction vehicles or roller tables in rolling mills, using at least one electric rotary- or travelling-field machine with variable angular- or linear- speed, fed by a.c. or d.c. via a current converter, uses a converter for supplying the stator winding of the electric machine, the converter providing three alternating currents, each with a superimposed direct current, and forming a three-phase system. Between the converter and the electric machine is a polyphase transformer, the prim. of which is in zig-zag connection and the sec. winding feeding the stator windings has a star or delta connection. In electric vehicles using nose-suspension traction motors, normal three-phase motors can be used, losses are reduced and, due to size redn. the un-cushioned mass is lower. In driving roller tables, the radial dimensions of the motor can be reduced and losses are lower.
