Patent EP-0404143-A1 (EP)
Inventor: UEBEL HELMUT
IPC: G01R31/02
Filed: 1990-06-21
Abstract: A circuit arrangement for monitoring AC loads, fed via capacitive cable feedlines, in railway signalling systems is disclosed which permits the current flow through the respective load to be reliably monitored by evaluating the current (I) fed into the cable feedline, independently of the length of the cable feedline. The current (I) flowing into the cable feedline flows through a monitoring element (G), which responds to the mean value with respect to time of the current flowing through it, only during one of the half cycles of the feed voltage (U). During the other half cycle of the feed voltage it is bypassed in a low-impedance fashion by a switch (S) controlled synchronously with the feed voltage. Since the capacitive reactive current has the mean value 0 during one half cycle of the feed voltage, the circuit arrangement detects only the real current component, which reproduces the load current, of the current fed into the cable feedline. <IMAGE>

Abstract: A gas containing H2S, SO2 and at least one of the carbon compounds COS and CS2, the total of the COS and CS2 contents being 0.01 to 0.5 times the H2S content, is desulphurised. In a first reactor (3), the gas is passed at temperatures of 160 to 190 DEG C through a catalyst bed (4) which contains a catalyst consisting of at least 80% by weight of TiO2. From the first reactor, a gas is taken off which contains elemental sulphur and has an H2S content of at most 0.5 times the H2S content in the gas to be desulphurised and a content of the carbon compounds COS and CS2 of at most 0.1 times the content of these carbon compounds in the gas to be desulphurised. The gas is cooled in a condenser, the elemental sulphur condensed out is separated off and the gas is passed through a second reactor (11, 11a), where H2S and SO2 are reacted at temperatures in the range from 110 to 160 DEG C over a catalyst (12) to give elemental sulphur which is adsorbed on the catalyst. While one of the two reactors (11, 11a) is connected for desulphurisation operation, the catalyst in the other reactor (11, 11a) is regenerated. <IMAGE>

Abstract: The heat-insulating engine with swirl chambers of this invention comprising thin members (5, 17) made of a monolithic ceramic material for forming the surface portions of swirl chambers (2) communicating with main combustion chambers (1) through communication ports (3), high rigidity outer wall members (6) made of a monolithic ceramic material for forming the outer peripheral portions, and swirl chamber inner wall members (4) made of a ceramic whisker material and disposed between the thin members (5, 17) and the high rigidity wall members (6). Therefore, this heat-insulating engine with swirl chambers (2) has high thermal stress assured by the thin members (5, 17), high mechanical strength secured by the high rigidity wall members (6) and high heat-insulating property attained by the swirl chamber inner wall members (4). Moreover, since the outer wall members (6) have high rigidity and since the swirl chamber inner wall members (4) can offset the stress of the thin members (5, 17) such as deformation, mechanical stress hardly acts on the thin members (5, 17), though the thermal stress alone is applied thereto. Accordingly, strength of the thin members (5, 17) can be secured.

Abstract: Ambulatory ECG data monitoring and recording method and apparatus that selectively captures recorded data based upon the occurrence of a defibrillation pulse from an implantable cardio-verter/defibrillator monitor (ICDM) device is described. The apparatus uses a single pair of skin electrodes (18a, 18b) to sample the ECG signal waveform and to monitor the voltage therebetween for the detection of a ICDM-produced pulse of characteristic amplitude and duration. ECG data are continuously stored (16) in a scrolling buffer of limited depth. Detection of a defibrillation pulse (20b) is treated as a trigger event, prompting the continuation of ECG data storage only for a limited further period of time after which the present ECG data record is captured. The buffered data are marked by the occurrence of the defibrillation pulse that prompted their capture, so that the information stored for subsequent playback indicates the timing relationship therebetween. A new buffer is initialized and ECG data recording and defibrillation pulse detection continues. Selectively capture-stored and marked ECG data can be played back to a remote site for diagnosis of a relatively long-­term, ambulatory cardiac patient monitoring and recording session. Optionally, the cardiac patient may manually trigger the capture-store of ECG data.

La lumière (16') provenant du premier déphaseur (22 à 26), est amplifiée et fournit une entrée pour le premier faisceau de pompage dans la cellule mélangeuse (40). Cette lumière passe ensuite dans le second déphaseur (44 à 48), afin d'entraîner un déplacement de fréquence vers le bas égal à deltanuB, et retourne ensuite sous la forme d'un second faisceau de pompage de cellule (16''). La lumière (18') provenant du troisième déphaseur (54 à 58) passe par le gouvernail de faisceau basse puissance (62) jusque dans la cellule (40), sous la forme d'un faisceau à signal d'entrée faible (18'').
