Title: Method and device for the optical equalisation of signals being transmitted via optical fibres
Inventor: KELLER GUSTL DIPL PHYS
IPC: H04B10/2525
Filed: 1982-04-03
Abstract: A method and a device for the optical equalisation of an optical signal having a delayed distortion in a long optical fibre (LWL) due to dispersion is specified. For this purpose, the signal is decomposed into individual components which have dispersion-induced, mutually differing delays, and each signal component is individually delayed in such a way that all the signal components have the same total delay. A mode-selective optical cable, a wavelength demultiplexer, a polarisation divider or, for RZ signals, a fast optical n-way changeover switch are proposed for the split. Short optical fibre segments of different lengths are used for individual signal delays of the signal components. The equalised signal appears at the output of an optical summer. One advantage is that it is possible to produce purely passive equalisers, which thus function without a supply of energy.

Patent DE-3220409-A1 (DE)
Title: Fully automatic roller shutter closure
Inventor: PLASBERG HANS-DIETER
IPC: E06B9/86
Filed: 1982-05-29
Abstract: The invention relates to a corner-deflecting steel bolt locking system which connects the respective roller armour at its lowest profiled rod rigidly to the guide rail by latching into a corresponding bore. The automatic release of the locking system is brought about when the roller armour bears firmly with its lowest profiled rod on the window sill and approximately three further profiles lie closely on one another. The unlocking is triggered by a pull strap fastened to the top profiled rod accessible from the inside being tightened, for the purpose of unlocking, only when the roller armour is operated properly and at the same time the lowest (three) profiled rods also are pulled to slotted position. The closure is to be mounted in a covered manner on the left and the right and can be applied easily by amateurs with reference to the mounting instructions without previous demounting or other modifications. It is consequently possible for the first time to fix roller armour in its lowest position fully automatically. The economic advantage lies in the     a) increase in burglarproofness,   b) reduction in mounting outlay,   c) avoidance of damage by faulty operation (e.g. electric drives), d) universal applicability on all roller armour types (e.g. wood, plastic, aluminium etc.).   <IMAGE>

Title: Heat pump driven by an internal combustion engine
Inventor: LUECK KLAUS DR
IPC: F24D19/10
Filed: 1983-04-20
Abstract: In the heat pump, the whole water circuit of which consists of two water circuits connected together, a three-way changeover valve is arranged between the first and the second water circuit such that this three-way changeover valve has connections for the first water circuit, for the second water circuit and for a boiler return duct. It is possible by corresponding switching of the three-way changeover valve and a cooling water thermostatic valve to effect the preparation of use water in the boiler through the first water circuit, which is acted on by the waste heat of the internal combustion engine, and simultaneously by means of the second water circuit, acted on by the heat pump process, to serve the heating system. Since in this case the relatively hot water of the boiler return duct does not reach the return duct of the heat pump, a high temperature level of the use water is possible without an increase in pressure on the cold side.
