Title: Multiplex carrier wave transmission system - has three signal groups and filter suppressing lower ends of converter and multiplexer bands
IPC: H04J1/04
Filed: 1975-06-12
Abstract: 761202 DW7651 000pp AB - BE-842523 The multiplex carrier wave transmission system each has a transmission and a receiving station, where the receiving station contains a number of sources each with one of three groups of signals. The transmitting station also contains a frequency converting and multiplexing circuit used to convert the first and second frequency bands of the first and second groups of signals and to multiplex them in the multiplex third and fourth frequency bands which are outside the thrid frequency bands of the converted first signals. The converted and multiplexed signals are combined with the third signal which has a frequency outside of the third frequency bands of the first signal, but inside the fourth frequency band of the second signals. The system incorporates filters (LPF2, 6) which suppress frequencies in the lower ranges of the frequency converters and multiplexers.

Title: Force:ventilation air heating system - passes all fresh air over fossil fuel heaters on outside walls first
IPC: F24D5/02
Filed: 1975-11-20
Abstract: The system is for heating of air for the force-ventilation of rooms by an exhauster fan, where up to a specific level above the floor the temperature must be kept within close limits over the whole area and no draughts may occur. It is partic. for pig sties used for rearing or fattening, and incorporates one or more air heaters. All fresh air from outside must, before entering the rooms, flow over air heaters in the room placed against outside walls and with inbuilt heat sources. Here it is heated to a temperature no more than ten or more degrees Kelvin higher than the desired constant temperature. The heat source is a fossil fuel, obtaining its combustion air from the outside air flowing through. The emerging combustion gases are returned to the current of incoming air, with which they are thoroughly mixed.

IPC: H05B47/11
Filed: 1987-10-29
Abstract: A device for producing alternating electric current of high frequency for power consumers such as fluorescent tubes (Ly1, Ly2) comprises a transformer with a winding (n3) connected in series with an output terminal (e) and active electronic components such as transistors (T1, T2) controlling the output current, the transistors being controlled by electric voltages produced by inductive feedback in feedback windings (n11, n12). Magnetic saturation is utilized to modify the inductive relationship in such a way that the transistors (T1, T2) cyclically change the direction of the output current. The feedback takes place in two magnetic cores (Tr1, Tr2) of the transformer, each core being provided with at least one further electric magnetization winding designated a command winding (n5, n6) as electric current is fed through the command windings to control magnetic saturation of the magnetic cores (Tr1, Tr2). As a result, combined control of the frequency and of the active electric power in the fluorescent tubes (Ly1, Ly2) is possible so that the luminous power may be controlled over a wide range while suitably high voltages can be maintained to ignite the tubes properly.
