Title: Recycling thermoplastic FRP materials - where binder and fibres are similar polymers, by disintegrating FRP and heating within limits to prevent thermal fibre length degradation
Inventor: THIELEN MICHAEL DIPL ING
IPC: B29B17/00
Filed: 1991-04-13

Title: Servo-assisted parking brake e.g. for private motor vehicle - has clutch to couple servo drive to brake linkage and with manual lever to operate servo control and for manual braking
Inventor: SIEPKER ACHIM
IPC: B60T13/74
Filed: 1992-02-24
Abstract: The parking brake is operated by a simple handbrake lever(6) which acts on a coupling unit(11) between the manual lever and the servo drive(2). The coupling unit connects directly to the handbrake cables(12). The operation of the handbrake lever initiates the servo drive to relieve the manual parking force. If the servo fails then the brake is applied manually. Control sensors(14,15) monitor the actual brake action and the programmed brake action and activate the servo drive when required. If the servo fails, then it is uncoupled from the unit by a clutch, allowing unimpeded manual action. The manual lever is cranked for mechanical advantage.

Title: Quasi-continuous leakage testing - supplying rapidly-diffusing reducing hydrogen gas to one side of component, and providing enclosed space contg. oxidising mixture at opposite side, and sensing reaction between gases using catalytic gas sensor
Inventor: RADEBOLD WALTER
IPC: G01M3/22
Filed: 1992-08-14
Abstract: Quasi-continuous leakage testing of similar components or workpieces delivered quasi-continuously, e.g. on a conveyer belt, involves using a rapidly diffusing, reducing gas such as hydrogen as a test gas diluted with inert components. The mixture is delivered to the workpiece from one side without flowing past it. A small closed vol. on the other side of the workpiece (5) is filled with air or another gas mixture contg. an oxidising component. This mixture is enriched with a reducing component (4) so that a catalytic detector (2) in the vol. detects the reaction between the oxidising component and the reducing component diffusing in via the leak. ADVANTAGE - Quasi-continuous leakage testing of similar components or workpieces reduces testing time by using parallel testing. Avoids problems due to helium-leak detector using mass spectrometer, requiring no vacuum and enabling use of large number of gas sensors to be used by computer. Allows unambiguous relationship between sensor signal and workpiece.
