Patent EP-0439474-A1 (EP)
Inventor: SCHNAIBEL EBERHARD
IPC: F02D41/14
Filed: 1989-10-06
Abstract: On détermine la résistance intérieure d'une sonde lambda en appliquant à la sonde une contre-tension continue synchronisée au moyen d'une résistance série, en mesurant les tensions de sortie lorsque la contre-tension est en circuit et lorsqu'elle est coupée et en calculant la résistance intérieure à partir des valeurs mesurées et des valeurs de résistance connues. La mise en oeuvre de ce procédé ne nécessite qu'une résistance série et un interrupteur, en plus des éléments d'un dispositif classique. La mesure peut être effectuée dans un intervalle de temps réduit, sans qu'il en résulte une charge de tension continue trop élevée susceptible d'affecter la durée de vie. La résistance intérieure mesurée est comparée à une résistance nominale et la durée du cycle pour un chauffage par sonde synchronisé avec une fréquence fixe est déterminée au moyen de la déviation de réglage ainsi calculée.

Abstract: A system to allow a network of stations (100) such as computers arranged in a star formation, to communicate with each other. The system has a protocol whereby stations (100) are granted access to the network, the protocol being tailored to star networks. Each station (100) may send a packet of data in each cycle of operation, provided that it indicated in a corresponding reservation slot (112), that it wishes to transmit. By examining the reservation slots (112) associated with stations (100) earlier in the cycle, each station (100) can determine the station (100) which is immediately preceding the one station amongst the stations which are to transmit data (i.e. have indicated in the corresponding reservation slot). On the basis of that determination the one station (100) transmits its data packet promptly after that preceding station (100) has transmitted its data packet; at least in certain cases, the station initiates transmission prior to having finished receiving the packet transmitted by the preceding station but with a timing to avoid data collision. Arrangements are shown whereby a data receiving station (100) can acknowledge receipt in a suitable acknowledgement slot (114) and wherein a busy station (100) can automatically reserve space. A variation to the protocol is given wherein reservations are note necessary, thereby speeding up operation in certain operating conditions.

Abstract: A stationary driving device for directing the goods carriers from the branch section into the main section of a power-and-free endless conveyor has two belts (13, 14) which circulate in parallel in the same horizontal direction and accelerate the load carriers (3) by means of a frictional connection. At the same time, the drive belts assume guide functions so that a building up of the load carriers on the running and carrying rail is effectively prevented. The drive device is also suitable for leading a loaded goods carrier evenly past the unloading point. Since no building up can occur here either, fully automatic unloading is possible when using known unloading devices. <IMAGE>

Abstract: Solute, especially copper, is recovered from a dilute solution by an adsorptive solute recovery process that, during elution of the absorbent bed, stores for recycling donor and receiver portions of effluent from the bed that range in concentration from barren to just less than product concentration and just less than product concentration to barren, respectively. The donor and receiver liquids are stored such that their solute concentration profiles as they leave the bed are maintained. The donor liquid is recycled through the adsorbent bed just prior to elution while the bed is treated with the receiver liquid after elution. Steady state operation is established after a number of loading and elution cycles, resulting in improved recovery of solute, reduced recycle rates and lower adsorbent inventory requirements.

Abstract: The invention relates to a method for the preparation of particulate pigmentary titanium dioxide. The method comprises reacting, in solution, a precursor titanium tetrahalide with sulfuric acid to produce an intermediate titanyl sulfate product. Following crystallization and recovery of this intermediate product from solution the crystallized intermediate is redissolved in an aqueous solvent medium and hydrolyzed at elevated temperatures to provide a particulate amorphous titanium dioxide intermediate product. After separation from the aqueous solvent medium, this intermediate product then is subjected to calcination at elevated temperatures to produce the desired particulate titanium dioxide end product.

Abstract: The device comprises a sandwich-type structure comprising a central layer for conveying light beams between optical transmission elements, and two external layers covering the faces of the central layer for guiding the light beams. The structure may be a deformable sheet or be obtained by moulding in order to match a predetermined surface. For example, the structure (4) comprises a reflecting parabolic edge (15) so that a beam coming from an optical fibre (2b) is collimated about an axis (Z'Z) of the cylindrical surface matched by the structure. Two such structures head-to-tail (4, 4') may form a rotary optical joint. Several pairs of structures (4, 4'; 41, 41') may be disposed concentrically. According to other variants, sandwich-type structures form a wavelength multiplexer-demultiplexer.   <IMAGE>

Title: Method of joining hollow plastics members by fusion.
Inventor: STAFFORD TREVOR GEORGE
IPC: B29C65/18
Filed: 1990-11-21
Abstract: Members such as natural gas distribution pipes (10, 12) of polyethylene or other plastics material are assembled with an internal liner (14) and heat is applied to the pipes externally by an electric heater assembly (18). After cooling the heater assembly is removed. The outer surface of the liner (14) fuses and bonds to the insides of the pipes. The pipe end portions fuse and bond across the interface (30). The liner is for example of polyethylene of molecular weight more than half a million containing finely divided carbon as filler. The liner is extruded and cold drawn to reduce its diameter to a close fit in the pipes. The applied heat causes the liner to expand more than the pipes. The liner retains enough stiffness to press against the insides of the pipes. Melt pressure and flow result and serrations on the liner give interlocking in the bond interface. The liner causes pressure drop in gas flow no greater than internal bead in butt fusion joining.
