Patent EP-0167268-A2 (EP)
Title: Rotary air valve
Inventor: HOFFMAN DONALD EDWARD
IPC: F24F13/10
Filed: 1985-05-29
Abstract: A rotary air valve is mounted in a case (10) for rotary movement about an axis (20) to close a pair of openings (34,36) and has a flexible elastomeric seal (52) that flexibly engages one or other of a pair of curved sealing surfaces (40,42) on the case to seal the respective opening. 
     The sealing surfaces have radii of curvature whose axes (48,50) are offset from the axis for the valve, so that a predetermined contact pressure is established along the seal at the respective curved sealing surface to tightly seal the associated opening in the closed condition, but the contact pressure diminishes to zero immediately the valve is rotated to open the opening, thereafter permitting further opening movement of the valve uninhibited by contact between the seal and the sealing surfaces.

Abstract: A real time monitoring and analysis of nuclear reactor vessel integrity is performed by monitoring reactor coolant temperature and pressure and fast neutron fluence, and generating therefrom a visual comparison of the reference nil-ductility transition temperature, RT  ndto  required for flaw initiation and the actual RT ndt  through the entire depth of the vessel wall at selected critical locations. Thermocouples located at the reactor core inlet and resistance temperature detectors, RTDs, disposed at cold leg conduits provide a measurement of the coolant temperature at the critical locations in the vessel. Under stagnant flow conditions, empirically developed conversion factors are applied to the RTD and thermocouple readings to provide the best estimate of coolant temperature at the critical locations.

Abstract: At least one string of several spaced measuring probes for the measurement of surface potentials is laid on the surface of the earth in such a manner that several probes are located outside and several probes are located inside the area of the surface over a reservoir. The potentials measured by all probes are polled in a sequence of periodic cycles. The signals from each probe are, during each cycle, filtered to separate higher-frequency changes in the signals from substantially lower-frequency changes in the signals. For the higher-frequency changes in the signals from each probe, an average and/or a sum are determined as a measure of the higher-frequency amplitudes for each probe. The higher-frequency amplitudes for the probes of a string of measuring probes are compared and the location at which the higher-frequency amplitudes for two adjacent probes change abruptly is taken to be the hydrocarbon/water interface in the underground reservoir.

Abstract: Zur Qualitätsmessung von Funkübertragungskanälen sind eine Reihe von Messverfahren bekannt, bei denen das Mass für die auftretende Störung entweder aus der empfangenen Feldstärke oder aus Amplituden-Schwankungen des HF-Trägersignals oder durch Messung des Ausserbandrauschens oder unter Zuhilfenahme eines besonderen Messtons oder unter Messung des Jitters durchgeführt wird. Hierbei wird durch Filterung und Mittelung der gefilterten Signale jeweils ein Qualitätsindikator abgeleitet. Zur Qualitätsmessung des Funkübertragungskanals während der laufenden Übertragung und zur Erfassung von Gleichkanalstörungen werden durch Störungen verursachte schnelle Schwankungen von durch Fading verursachten, langsamen Schwankungen getrennt, gemessen und der Qualitätsindikator aus den Messgrössen von schnellen und langsamen Schwankungen abgeleitet. Durch die getrennte Messung der Summe von der Leistung des Empfängereingangsrauschens und der Leistung von Gleichkanalstörern kann auf einfache Art und Weise eine Auswahl der Feststation mit bestem Empfangsverhältnis vorgenommen werden.

Abstract: Covers are a mechanical and acoustic protection for a hydrophone system. Shaping and choice of material reduces flow noise, prevents cavitation and achieves acoustic transparency for water-borne noise. The new cover is intended at the same time to prevent radiation of interference noise which is produced by the structure-borne noise of the support vessel and transmitted to the cover. The wall of the cover is a laminated composite consisting of one or more dimensionally stable layers as supporting element and damping layers for flexural waves on top of and inbetween them. Material choice and dimensioning achieves the acoustic transparency for water-borne noise. Bow and keel domes and also lateral covers can be produced with such a laminated composite. <IMAGE>
