Patent DE-4308241-A1 (DE)
Inventor: RUSSELL DAVID M
IPC: H03K3/84
Filed: 1993-03-11
Abstract: A digital controller (12) is arranged to provide digital signals to audio modules (10), the digital signals comprising both clock signals and data. All of the logic circuits (18, 22, 23) of the controller (12) and of the modules (10) are arranged to be clocked on the receipt of a rising edge. However, to avoid interference from regular clock pulses, the clock pulses are altered to have a variable mark-space ratio. This means that the clock pulses arrive at random times and have random widths and thus appear to be randomised. The utilisation of randomised clock signals can avoid tones appearing in an audio system, and also avoids interference effects in other electrical systems. The use of randomised clock signals is particularly helpful when trying to design digital circuits which meet current regulations controlling electromagnetic emissions.

Title: Optical force measuring device
Inventor: HOLZAPFEL WOLFGANG DR ING
IPC: G01L1/24
Filed: 1993-07-05
Abstract: The optical force measuring device consists of a crystalline solid material (101) which has both photoelastic and laser-active properties and which carries at its ends the resonator mirrors (104, 105) and thus forms a monolithic optical sensor oscillator. By means of a radiation source (102) and an input coupling optics unit (103), the photoelastic sensor oscillator is excited into laser activity. If a force F acts in the orthogonal direction with respect to the resonator axis on the material, which is connected to a rigid frame (100) which leads out the forces, the coupled-out frequency components  nu 1 and  nu 2 then change and, in terms of their difference, form a force-dependent signal. The optical force measuring device, having a frequency-analog output signal and a large measuring range, can be used to measure the force or a measured variable derived therefrom, such as acceleration or mass. <IMAGE>

Title: Fast, small stealth minelaying and minesweeping ship for use in the navy and the marine corps
Inventor: KRECH HANS DR
IPC: G01S7/38
Filed: 1994-03-24
Abstract: Minelaying and minesweeping ships cannot lay and sweep mines in the enemy defence sector because they can be located by the enemy radar and then attacked. Through the use of the stealth technology for fast, small stealth minelaying and minesweeping ships, the ships can no longer be located by the enemy radar. They can lay and sweep mines at night under almost complete electronic and optical camouflage in especially well protected enemy defence sectors (harbour installations, front coastal zones, sea routes). They are excellent for unobserved minesweeping off enemy coasts in preparation for a sea landing. Fast, small stealth minelaying and minesweeping ships can be used in the navy or in larger marine corps, for instance the US marine corps.

IPC: B29C73/28
Filed: 1994-09-09
Abstract: Plastic moldings can be joined using one- or two-component adhesives, with the joint seams being bridged by metal strips. These metal strips are at least partially imbedded in the adhesive layer. This method is especially well suited to repairing damaged plastic moldings, in particular automobile parts such as bumpers. The moldings repaired by this method regain their original performance capability, particularly their inherent stability, impact strength and outward appearance. When scrapped, moldings that have been repaired in this way can be fully recycled using standard processes.
