IPC: H01M50/193
Filed: 1991-09-13
Abstract: Méthode servant à fabriquer des matériaux en céramique devant rester stables dans des environnements extrêmement corrosifs se caractérisant par une forte activité de métal alcalin, une forte activité de soufre/sulfure et/ou des haloïdes fondus à des températures de 200-550 °C ou un sel organique (y compris SO2 et SO2Cl2) à des températures de 25-200 °C. Ces céramiques de sulfure forment des composés stoechiométriques (phase unique) avec les sulfures de Ca, Li, Na, K, Al, Mg, Si, Y, La, Ce, Ga, Ba, Zr, et Sr et présentent des points de fusion suffisamment bas; elles possèdent une excellente mouillabilité avec beaucoup de métaux (Fe, Ni, Mo), qui permet de former facilement des scellements métal/céramique. Des compositions de céramique sont aussi formulées de manière à bien correspondre au coefficient de dilatation thermique des constituants métalliques adjacents.

IPC: D06B23/04
Filed: 1992-06-12
Abstract: So that, with a guiding device consisting of a guide ring (1), faults in the circulation of a textile strand (2) can be eliminated with care, the guide ring (1) fastened to a pivot axle (5) is equipped with a carrier (6) on its side located opposite the pivot axle (5). In the event of a pivoting movement of the guide ring (1) limited to approximately 270 DEG , the carrier (6) is also pivoted correspondingly, the textile strand (2) looping increasingly round the carrier (6). This thereby exerts, during the pivoting movement, a tensile force restricted essentially to the direction of circulation of the strand (2), so that said tensile force extends to the region which is the cause of the circulation fault. <IMAGE>

Abstract: A housing (2) of a measured-value transmitter (1) for determining the flow rate of a flowing liquid by measuring the mean flow velocity with the aid of ultrasonic signals encloses a cavity which is divided by a partition (3) into a first distribution chamber (4) used for supplying the liquid to a measuring system and a second distribution chamber (5) used for draining the liquid from the measuring system. The two distribution chambers (4, 5) are connected to one another by at least one measuring tube (6, 6', 6'') penetrating the partition (3). Opposite to the two ends of the measuring tube (6, 6', 6''), measurement transducers (7', 8', 7'', 8'') are arranged which are in direct contact with the liquid. The measured-value transmitter contains means by which the total flow of the flowing liquid is divided into at least two part-flows of known dividing ratio. At least one of the part-flows flows through the measuring tube (6', 6''), measurement transducers (7', 8'; 7'', 8'') being arranged opposite to the ends of this measuring tube (6', 6''). Such measured-value transmitters are suitable for detecting large flow rates. <IMAGE>

Title: Hydroextractor
Inventor: MASUMOTO NORIO
IPC: B01D29/01
Filed: 1992-02-19
Abstract: A hydroextractor in which a liquid material to be processed can be introduced into a hydroextracting chamber under a small pressure and the chamber can be filled with the material in a short period of time to thereby improve the operational efficiency, and a cake of the hydroextracted material can be easily removed from the hydroextracting chamber. For these purposes, this hydroextractor is arranged such that upper and lower filter cloths 4, 9 are provided at the top and the bottom of the hydroextracting chamber 27 extending substantially horizontally, and that a diaphragm 8 shaped like an inverted dish is disposed on the upper surface of the upper filter cloth 9. Further, a pressure chamber 32 is provided on the upper side of the diaphragm 8. The hydroextracting operation is performed by filling the liquid material in the hydroextracting chamber 27 and generating a pressure in the pressure chamber so as to press the diaphragm 8 downwardly.

Title: Automatic phase adjustor for video camera
Inventor: SANO TOSHIYUKI
IPC: H04N5/378
Filed: 1992-02-27
Abstract: An automatic phase adjustor for a video camera is provided for carrying out phase matching in accordance with the phase-correcting amount freely set from the external however delayed the signal is in a video-signal processing system. A first counter (3) supplies a pulse for driving an imaging element (1) to a phase shifter (6). The phase shifter (6) serves to delay the pulse by the amount of delay appearing in the processing circuit (5). The delayed pulse is input to a phase comparator (10). The phase comparator (10) compares the delayed pulse with a pulse sent from a second counter (8) for generating a synchronous signal. Based on the compared result, a gate circuit (9) is interrupted so that the horizontal phase difference between the video signal sent from the imaging element (1) and the synchronous signal sent from the second counter (8) may reach zero when both of the signals reach an encoder (7) for combining them.

Abstract: A moulded screw-threaded plastics closure has depending from the underside of the top (11) an annular sealing portion (14) spaced inward of the skirt. The sealing portion includes a plug part (20) with a sealing rib (52) for engaging the internal surface (16) of the neck of a container, a radially outwardly projecting flange (24) above the plug part, and a waisted pivot part (28) disposed between the flange and the top. As the closure is applied, the sealing rib (52), first moves into sealing engagement with the bore of the neck of the container, and then the flange (24) comes into engagement with the top (32) of the neck of the container and causes the sealing portion (14) to pivot outwards about the part (28) to tighten the seal. An internal rib (49) on the skirt engages the outer surface of the neck of the container to form a secondary seal. Forms of stop may be provided for limiting the movement of the closure and/or the pivotal deflection of the sealing portion to prevent over-tightening during application of the closure. Gaseous pressure within the container tends to increase the sealing pressure between the plug part (20) and the bore, and the top (11) of the container is suitably stiff to resist deformation by the pressure.

Abstract: A component such as a laser includes two superimposed light guides, one active (101), the other passive (102). The width of the active guide decreases in a rear part (TB) of a mode transition section (TB, TC) in order to couple a "narrow" optical mode (NA) which is amplified and guided by the active guide, to a "wide" mode (NC) which is guided by this passive guide and which has a larger girth than this narrow mode. The width of the passive guide (102) decreases subsequently in a forward part (TC) of this section in order to couple the wide mode to an even wider circularised mode (NE).

Inventor: HEDDERLY DAVID LESLIE
IPC: H04J3/06
Filed: 1991-12-11
Abstract: In Multistation Demand Assigned Time Division Multiple Access Systems digital information is communicated from a head end to a population of oustations so that all the outstations receive the same stream of digital information and select their traffic from it. Traffic is only sent to and from an outstation when there is a demand for it. As the outstations are at random ranges from the head end it is necessary to know the time of travel for a burst of information so they arrive at the head end sequentially. The traffic dependent free time is consolidated and made available for ranging-in outstations.
