Inventor: KAPPEL JOHANNES
IPC: D21C9/10
Filed: 1990-06-25
Abstract: The invention relates to a method and device for the washing of a medium consistency fibrous slurry, especially a chemical pulp slurry in which the slurry is fed at an inclined angle onto a substantially horizontal portion of circulating  filter belt, and then distributed over substantially the entire working width of the filter belt.          The distributed slurry is then washed with a washing liquid under localized pressure to produce a slurry having a medium consistency range, i.e., about 8 to 15 percent.  In order to increase the consistency to 20 to 40 weight percent, preferably about 30 to about 35 weight percent, the washed slurry is passed to a pressing zone.

Abstract: Résumé. Je propose ici la nouvelle façon de construir la chaussée des autoroutes,des routes,des rues et des trottoirs.Cette chaussée consistera selon ma proposition des dalles préfabriquées,fait de béton armé.Cette chaussée ne pourra pas être construit d'une seule couche des dalles,mais on doit placer deux ou trois couches des dalles, une couche sur l'autre couche et si on veut on peut placer encore une troisième couche des dalles carrées ou hexagonales sur les deux couches de cette chaussée.Les dalles de la deuxième couche ne seront pas placées directement sur les dalles de la première couche,mais chaque dalla de la couche supérieure sera placée de façon,qu'elle reposera sur quatres dalles inférieures en même temps.Chaque qu'elle de la dalle carrée de la couche supérieure sera placée sur le centre d'une dalle inférieure,pour que le poids d'un camion lourdement chargé pouisse se transmettre au terrain sous ces dalles sur le plus grande aire que possible.On augmente Gomme ça la résistance de ce terrain et sa capacité de suporter le poids des camions le plus gros.En même temps on aura des routes durables,qui n'auront pas besoin que très peu d'entretien,parce que cette chaussée ne peut pas se fissurer,ni se désintégrer ornières causées par le passage des camions lourdement chargés sur cette chaussée ne vont pas se former non plus.A cause de ces ornières,les autoroutes du Québec se déteriorent.

Title: Method and apparatus for detecting a broken ph sensor
Inventor: BARBEN TED R II
IPC: G01N27/36
Filed: 1990-09-28
Abstract: ABSTRACT OF THE DISCLOSURE          A break  in  the  enclosure  of  an  electrochemical sensor, such as a pH sensor,  is detected by including in the enclosure a set of elements which are spaced from each other  and  which  are  made  of  metals  having  dissimilar electrical potential  and  reactive  characteristics.   When moisture   enters   through   the   broken   enclosure,   an electrical potential is created between the elements which can be detected by a voltmeter.  One of the elements is advantageously   made   of   zinc   and   the   other   is advantageously made of  silver  or  silver  chloride coated silver.   The  elements  in  the  form of  ribbons  or  wires within the enclosure, may simply be portions of the leads connected to the half cell and reference electrode of the sensor.  Salt may be included in the enclosure to produce an electrolyte when moisture enters the enclosure.

Title: Melting fuse
Inventor: MUESSLI DANIEL
IPC: H01H85/045
Filed: 1990-03-15
Abstract: (57) Abstract In order to protect in particular electronic circuits from overheating, current or voltage surges, and transients, a fuse is proposed which includes a fuse wire (7) be-tween two connecting wires (8a, 8c), conveniently in the form of resistance wires, on a ruse body (1). The fuse wire (7) is routed over several partitions (5a, 5b, 5c), advanta-geously three of different heights, and through two openings (6a, 6c) in the central zone (1b) of the fuse body, to connector points (3a, 3c) where it is connected to the re-sistance wires (8a, 8c). The fuse provides protection simultaneously against voltage and current overloads, transients and thermal overloads, and can readily be incorpo-rated in any circuit since it is about the size of a resistor.

Abstract: TITLE Process for Spinning High-Strength, High-Modulus Aromatic Polyamides ABSTRACT A process for spinning high-strength, high-modulus, aromatic polyamide filaments is disclosed in which an acid solution containing at least 30 g per 100 ml acid of aromatic polyamide having an inherent viscosity of at least 4 and chain extending bonds which are either coaxial or parallel and oppositely directed is extruded through a layer of inert noncoagulating fluid into a coagulating bath and then through a spin tube along with overflowing coagulating liquid.  Additional coagulating liquid is jetted symmetrically about the filaments in a downward direction forming an angle of 0°C to 85° with respect to the filaments within about 2.0 milliseconds from the time the filaments enter the spin tube.  The flow rates of the jetted and the overflowing coagulating liquids are maintained constant.  In the process, the mass-flow ratio, i.e., the ratio of the mass-flow rate of combined coagulating liquid to mass-flow rate of the filaments,     greater than about 250, preferably greater than about 300, and the momentum ratio of jetted to overflowing coagulating liquids of greater than about 6.0 is employed.  Also, the average linear velocity of combined coagulating liquids in the spin tube is less than the velocity of the filaments exiting from the spin tube.           Doc. P.12

Abstract: A fully internally manifolded fuel cell stack is provided by each separator plate and electrolyte in the fuel cell stack having a plurality of aligned perforations forming gas manifolds extending for the length of the cell stack.  Each perforation through the separator plate is surrounded by a flattened manifold wet seal structure extending to contact the electrolytes on each face of the separator plate to form separator plate/electrolyte wet seals under cell operating conditions.  Conduits through the extended manifold wet seal structure provides gas communication between one set of manifolds and the anode chambers on one face of the separator plates, conduits through the extended manifold wet seal structure on the opposite face of the separator plates provides gas communication between a second set of the manifolds and the cathode chambers on the other face of the separator plates, and conduits through the extended manifold structure of a reactant gas manifold provides communication to interspersed reforming chambers.  Extended wet seal structures formed of thin plate metal provide limited flexibility and resiliency to assure good sealing.  This structure provides fully internal manifolding of and separation of fuel and oxidant gases to each of the unit fuel cells in the fuel cell stack while providing reactant gas to reforming chambers interspersed along the cell axis to reform hydrocarbonaceous gas and supply enhanced hydrogen content to the fuel supply manifold.

Title: Electronic voltage- and temperature-regulated battery-heater
Inventor: BEHNISCH JURGEN
IPC: H01M10/637
Filed: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE           This battery heater allows every battery independent of position (i.e.automobile load accumulator) to be heated up without ant external power sourco, and to improve the starting power while external temperature is low. The circuit is constructed in such a way that an internal temperature below 0° C in the battery is prevented for a long period of time, and that a regular internal temperature of ca. 15° C in the battery is accomplished in most cases.  In case the battery heater is switched on for a longer period of time, and the battery voltage drops below 12 V the battery heater will shift down to a minimal current of ca. 8 mA which is discharging the battery rather insignificantly.  The battery heater functions maintenance-free, without any mechanical switches, and is only activated by a starter voltage of ca 14 V, in order not to influence the storage of the filled battery.           The durability of lead accumulator is, when using the battery heater, prolonged due to the constant internal temperature, because at the same time the development of lead sulfate (Pb SO4) in too large crystals is prevented or delayed in most cases.             In an electronically heated automobile starter battery the same Ah starting power i accomplished as in a battery of a size ca. 25 % bigger.  This way the battery size can be reduced, and the enviroment is being charged with less lead acid waste.
