Patent DE-4108230-A1 (DE)
Inventor: BORSCHEL HARTMUT DIPL ING
IPC: H04J3/14
Filed: 1991-03-14
Abstract: In known repeaters complying with CCITT Recommendation G.958, repeater sections are monitored by monitoring the transmission error probability of SDH signals (synchronous digital hierarchy) by means of parity evaluation. This requires the splitting-up and reconstitution of the SDH signal. Specific signal processing devices, such as multiplexers and demultiplexers, which are not needed for repetition of transmission signals as such, are required for this purpose, which causes a considerable power loss. In the repeater (RE) according to the invention, the transmission error probability is determined by comparison of a known word in the header part of an STM-N signal with a reference word. The transmission error probability is derived from the result of the comparison and fed via an error line (FL) to a central station. The transmission error probability can be transmitted in an STM-N signal in that it is effected via a repeater complying with CCITT Recommendation G.958 by using, for example, the service channel. <IMAGE>

Title: Sprung sealing gasket for coupling pipelines - has shaped elastomer seal with folding action to contain sprung ring to protect from corrosion
Inventor: ARLT GERHARD
IPC: F16L21/03
Filed: 1991-09-13
Abstract: The shaped gasket seal (3) fits over the end flange of the outer pipe section and is held in place by the sprung ring (4) embedded in the elastomer profile. A hinged flange (3) of the seal extends inwards and is pressed flat onto the gasket by inserting the inner pipe section (13).

The sprung ring presses the gasket retaining lip (11) into a groove inside the outer pipe. The hinged flange has a thickened profile to ensure a good seal onto the inner pipe. ADVANTAGE - Simple gasket fitting, sprung ring fully protected, no inadvertent removal of seal.
Patent DE-4131545-A1 (DE)
Inventor: ZIMMERMANN HORST DIPL ING
IPC: B60G3/01
Filed: 1991-09-21
Abstract: In shock-absorbing struts (1) with a hydraulic wheel-drive unit, it is usual to feed the hydraulic fluid through flexible hoses to the hydraulic motor. In order to avoid damage to these hose lines, the fluid is fed in the new shock-absorbing strut through the strut (1) itself. Both the hydraulic-fluid feed and return lines have a telescopic connector (44, 51, 48, 50) which is fixed on one side to the outer guide housing (3) and connected on the other side to a revolving joint (11) which is fixed longitudinally with respect to the cushioned support element (3). The connections for the hydraulic motor (feed and return) are therefore fixed with respect to the steerable support element (3).

Title: Echo compensation for 2-wire to 4-wire telephone line interface - using artificial echo signal and calculated compensation attenuation to determine residual echo limiting threshold
IPC: H04B3/23
Filed: 1991-10-30
Abstract: The echo compensating method involves using an artificial echo signal obtd. from an echo signal received from a remote subscriber and a signal component obtd. from an adjacent subscriber. The echo attenuation is determined by subtracting an input level of a transmission path from a reception path signal level. The sum of the echo attenuation and the compensation attenuation is determined by subtracting the transmission path output level from the reception path signal level. The echo attenuation is subtracted from this sum to provide compensation attenuation. A residual echo limiting threshold is obtd. by subtracting the compensation attenuation from the artificial echo signal level, for comparison with the transmission path output level, to provide a control signal for the residual echo limitation. The reception path signal is delayed to synchronise it with the echo signal at the transmission side. ADVANTAGE - Improved echo compensation.

Title: Electroconducting plastic rollers - produced by mixing metal strips or wires with polymer in extruder, pref. plus glass fibres and polyamide, and moulding to shape
IPC: H05F3/00
Filed: 1991-12-16
Abstract: Electroconducting plastic rollers are produced by mixing 30 - 70% wires, strips of metal foil or other metallic strips with 30 - 70% polymer, plasticating and homogenising the mix in an extruder, and moulding the mix into rollers. One pref. version uses polyamide plug glass fibres. Pref. copper is used as the metal and the addn. of glass fibres to the mix assists homogenising. The addition of polyamide beforehand prevents oxidn. of the metal. In use a spring-loaded conductor touching the roller ensures continuous earthing, e.g. when doors run on the rollers concerned. In Fig. 3 there is a centre hole (7) for mounting on a bearing. Annular recesses (8) on the sides save weight. A circumferential groove (9) enables the roller to run on a track. ADVANTAGE - The prods. do not become electrically charged and hence cannot give a shock to anyone touching them. They also have the usual advantages of plastic materials (e.g. corrosion resistance, self-lubrication etc.).

Title: Transmission signal for binary data esp. for video tape recording - has table assembled so that with help of additional bit minimum and maximum run length in NRZI signal are maintained
Inventor: SCHOLZ WERNER DIPL ING
IPC: H03M13/51
Filed: 1992-05-25
Abstract: In the transmission signal m-bit data words selected n-bit code words are also assigned a table. Additional bits are inserted to generate signals between the code words.

The table is assembled so that, with the help of an additional bit a minimum run-length of Z and a maximum run-length of 6 in the NRZI signal can be maintained. In addition the spectrum of the NRZI signal is influenced. USE/ADVANTAGE - Particularly for recording digital video data with magnetic tape apparatus with higher density, while offering possibility of providing a large section of faulty bytes already in channel decoder with error flags.

Title: Broadcasting cells in ATM coupling structure of packet communication system - retransmitting cells in coupling stages and determining respective junction lines using added routing and broadcasting information
Inventor: HUMMEL HEINRICH
IPC: H04L45/16
Filed: 1992-09-14
Abstract: The method involves adding routing and broadcast information to the internal cell head of the communications system. This enables retransmission of cells in the coupling stages (KS) and determination of the respective junction lines (VL) to the next coupling stage, or the path to which the newly transmitted cell is to be transferred. The broadcast information is used to indicate a path branch in the respective coupling stage, and to cause a new transmission of the respective cell. In each coupling stage, the information relating to the respective stage is removed and the remaining information is added to the cell head formed in each coupling stage, for transfer to the following stage via the junction line. ADVANTAGE - Allows connection of cells via n-stage coupling structure, while maintaining self-control principle. Eliminates memory requirement for path branches.
