Title: Method and device for the fault location of short circuits and earth leaks in high- and medium-voltage networks
Inventor: BRAUNER GUENTHER DR ING
IPC: H02H3/04
Filed: 1987-12-31
Abstract: The object of the invention is a method and a device for the fault location of short circuits and earth leaks in high- and medium-voltage networks having nodes and partial sections. By means of distance protecting devices arranged in the respective network, the impedances are measured in the case of a fault and combined in accordance with the respective switching condition of the high- or medium-voltage network to form impedances of power supply units in which the fault may possibly have occurred. The impedances are compared with calculated impedances which are determined from the electrical characteristic values of the network, adapted to the network structure and the switching condition of the high- or medium-voltage network. In the case of agreement or of agreement within a permitted tolerance between the impedance measured corresponding to a fault location and the calculated impedances, the partial section of the fault location is determined. The fault location is calculated from the impedances. In the case of ambiguity, those conductor sections are reported as possible fault locations, whose measured impedances agree with the calculated impedances. <IMAGE>

Title: Fifthwheel coupling
Inventor: KUEBLER DIETER
IPC: B62D53/12
Filed: 1988-02-09
Abstract: The invention relates to a fifthwheel coupling for coupling and uncoupling a semitrailer, having a fifthwheel kingpin, to or from a tractor. The fifthwheel coupling can be released via an operating member (Z2) which can be operated by means of a remote-control member (33) and can be coupled by inter-engaging coupling parts (fifthwheel kingpins 4, 8) of the two vehicles to be coupled. The invention furthermore relates to a self-locking device (22, 31, 32, 32') which keeps the operating member (Z2) activated after it has been activated by operating the remote-control member (33) until it has been established that the vehicles have been uncoupled. To this end, a sensor (23) for the uncoupled condition is arranged adjacent to the open position of a pivotable coupling claw (4) for the fifthwheel kingpin, which claw can be brought into engagement with a locking hook (8) which can be operated by the operating member (Z2), is monitored with regard to its locked position by means of a sensor (22) and is coupled to a release device (10) which can be operated by a further operating member (Z1) and is monitored in its closed position by a sensor (21) for the coupled condition. The locking lever (8) and the release device (10) can be brought into the release position with regard to the coupling claw (4) by means of the operating members (Z1, Z2).

Inventor: WILLEKE HORST DIPL ING
IPC: B21B1/08
Filed: 1988-02-17
Abstract: For the central rolling out of the webs or to avoid deep pass incisions of the rolls/former rolls and to avoid undercuts due to the outer portions of the section/flanges in the production of H, I, U, T, L, double T sections and similar rolled material, the trick of folding out is employed. After the upset passes the flanges are formed by folding, i.e. by a flat and edging pass, during finishing-rolling. 
<??>The invention proposes a new folding method in accordance with the principle of the three-roll bending method. Another solution to the same problem comprises a folding method which employs back-up rolls for the first portion of the section or web, the said rolls not touching the inner flange faces or inner faces of second portions of the section. 
<??>Corresponding new roll stands and rolling mills require lower levels of investment, exhibit less roll wear and have a shorter overall length. Further advantages are the smaller requirement for former rolls and lower energy consumption.

Title: Safety system
Inventor: GURRUCHAGA GARAGARZA JOSE AGUS
IPC: F23N5/04
Filed: 1988-03-11
Abstract: By means of the invention a safety system, in particular for gas-operated water heaters, is described. The safety system operates with the bimetallic strip and an essentially cylindrical, relatively long valve body. The valve body bears shut-off pistons which in turn interact with closure seats. Between the two closure seats is the gas feed line for the pilot light, while the other gas feed line to the burners has intermediate connection of a corresponding automatic valve outside one of the closure seats. The safety system according to the invention has the advantage that it additionally acts on not only the gas feed stream to the burners but also to the pilot light and thus shuts off the gas feed in the event of the burner being extinguished.

Patent DE-3826858-A1 (DE)
Title: Two-band filter
Inventor: SPILLE JENS
IPC: H03H17/02
Filed: 1988-08-08
Abstract: Two-band filters are used in order to build up filter banks for so-called subband encoders for audio and video signals. Such a filter consists of at least one first filter arrangement of a complementary low-pass/high-pass filter for dividing the signal into two frequency bands and at least one further filter arrangement for combining the two frequency bands. A coder and a subsequent decoder can be inserted between the first and second filter arrangements. The individual filters forming the filter arrangement exhibit a time-limited pulse response. To obtain error-free overall transmission, it has hitherto only been possible to implement the arrangement by means of conjugate quadrature filters (CQF) which can be accurately calculated. According to the invention, the individual filters are implemented as non-recursive digital wave filters (NWDF) with predeterminable phase response for simplifying the expenditure. The calculation can be carried out on the basis of CQF filters and transposed to the NWDF filters. The filters can be used in subband encoders, preferably for data reduction in digital broadcast transmission.

Title: Points for suspended conveying systems
Inventor: BUCHSTALLER MICHAEL
IPC: E01B25/26
Filed: 1988-08-29
Abstract: In suspended conveying systems, the points are the crucial components. Points systems used hitherto have, with a plurality of axes, been extremely complex to control. The new system presented makes it possible to select up to three travel paths manually or automatically simply by turning or pushing, it being possible to travel through the points without problems in both directions like a normal rail. The new feature of this system is that it is no longer necessary to pivot, position and adjust different rail pieces, simple turning being sufficient to change direction.

Title: Colorimeter
Inventor: ROESLER GERHARD DR
IPC: G01N21/47
Filed: 1988-12-23
Abstract: In colorimeters in which measuring light is irradiated onto a sample surface to be examined and the measuring light radiated back at a specific observation angle is converted and evaluated optoelectrically into a signal representing its spectral distribution, there exists the difficulty that, in the case of directionally reflecting sample surfaces, such as metal effect paints, a single measuring geometry is not sufficient. Therefore, a plurality of measuring light sources 2 to 5 are arranged at different illumination angles. An electronic evaluation device for the electric signal representing the spectral intensity distribution triggers the measuring light sources 2 to 5 a short time after each other and evaluates the respective electric signal produced as a function of the respective illumination angle and observation angle. To increase further the number of measuring geometries provided, the measuring light sources 2 to 5 and the measuring lens 7 can preferably be pivoted together through specific angular steps. <IMAGE>
