Patent DE-3212321-A1 (DE)
Title: Zero-current signalling device for a double converter with no circulating current
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/162
Filed: 1982-04-02
Abstract: The zero-current signalling device is used for identifying zero-current signals (A) for a control device of a double converter (1) with no circulating current. The AC voltage (UAC) at the input of the double converter (1) and the DC voltage (UDC) at the output are identified by means of voltage detection devices (5, 6). The sum and difference respectively of the determined voltages (UAC, UDC) are formed via an addition point (7) or a comparator point (8) respectively and are supplied to voltage magnitude signalling devices (9, 10). In the event of an instantaneous deviation in the time responses of the determined voltages (UAC, UDC) outside predetermined limiting values (x), current zero signals (A) are emitted via a logic gate (11) to the control device in order to switch over from one sub-converter of the double converter (1) to the other. Double converters are used especially for supplying DC motors. <IMAGE>

Patent DE-3312144-A1 (DE)
Title: Insertion system for multifunctional use of road safety and/or information devices
Inventor: HIRTH HELLMUTH
IPC: E01F9/669
Filed: 1983-04-02
Abstract: The invention consists in that, through the insertion of different profiles, a number of devices can be inserted without expensive assembly. In addition, damaged devices can easily be exchanged for new ones. A sleeve fastened in the ground (in a concrete bed or with ramming profile) receives the support profile. This support profile is only inserted into the ground sleeve and secured. The individual devices are then firmly connected to the support profile. The support profile at the same time also represents an intentional weak point, in order to protect the ground sleeve in the event of an accident, in that it snaps off above the ground sleeve. By the insertion of a further sleeve in the upper part of posts, further devices (e.g. snow poles in road delimiting posts) can be arranged here in addition. The ground sleeves are protected against dust and dirt by dirt collectors (brushes etc.).
