20080256859 | Reformer Mixing Chamber and Method for the Operation Thereof - The invention relates to a reformer mixing chamber comprising a water vapour-air mixture feeding line and a binary nozzle for supplying a fuel-air mixture, wherein said mixing chamber is rotationally symmetrically shaped and the flow direction of the binary nozzle and the water vapour-air mixture feeding line are axially and oppositely oriented. The inventive mixing chamber is advantageous in that it makes it possible to carry out the fuel as complete as possible conversion. For this purpose, the fuel-air mixture is supplied to the mixing chamber by means of a second binary nozzle, thereby making it possible to supply the mixing chamber with the water vapour-air mixture by another feeding line, wherein the fuel-air mixture flows in the direction opposite to the water vapour-air mixture. | 10-23-2008 |
20090029210 | Low-Temperature Fuel-Cell Stack and Method of Operating Same - The invention relates to a low-temperature fuel cell stack comprising a specific device for the supply of fuel. Said low-temperature fuel cell stack is characterised in that, in addition to the central fuel supply device, it comprises a supply or storage device for a liquid fuel, and a plurality of separately controllable dosing devices that lead into the central fuel supply device, especially respectively upstream of a distribution channel to the individual cells. Controllable valves, controllable piezoelectric pumps or thermally controllable supply elements are suitable as dosing devices. The invention also relates to a method for operating one such low-temperature fuel cell stack, which advantageously enables a defined concentration of fuel, or a defined humidity of the oxidation medium, to be adjusted at certain points in the fuel cell stack, especially on the inlet for the individual cells. | 01-29-2009 |
20090136798 | Autothermic Reformer - The invention relates to a device for producing a product gas which is rich in hydrogen, comprising a reformer part which comprises an inlet for a fuel/oxidation agent mixture, an inlet for a water/carrier gas mixture, a catalytic surface and a first heat exchanger. Said device also comprises a combustion part which comprises an inlet for an anode residual gas from a fuel cell, an inlet for an oxidation agent, a catalytic surface and a second and a third heat exchanger. The reformer part and the combustion part are connected via lines which are used to guide a water vapour/catrier gas mixture and for directing the reformat. According to the inventive method for producing a product gas which is rich in hydrogen, a first mixing chamber guides a water vapour/carrier gas mixture via a line and a fuel/oxidation agent mixture via a nozzle. The fuelwater vapour/oxidation agent/carrier gas mixture is catalytically converted into a product gas which is rich in hydrogen in exothermic and endothermic reactions. The anode residual gas from the fuel cell is catalytically converted in exothermic reactions into waste gas having few harmful substances. The heat required for evaporating water into water vapour in the water vapour/carrier gas mixture is partially produced by cooling the product gas which is rich in hydrogen and partially by cooling the waste gas of the combustion which contains few harmful substances. | 05-28-2009 |
20100051873 | PROCESS FOR EVAPORATING A LIQUID FUEL AND A MIXING CHAMBER FOR PERFORMING THIS PROCESS - A process with which a liquid fuel is evaporated completely in two stages is provided. In the first stage, the fuel is mixed with a hot primary medium and partly evaporated. In the second stage, the already evaporated fuel fraction is partly oxidized, which provides the heat for the complete evaporation of the fuel fractions which are yet to be evaporated. A fuel-air mixture for a reformer can be obtained with an advantageous embodiment of the process, in which the fuel is mixed homogeneously with oxidizing agent in the inventive evaporation. For the performance of the process, a mixing chamber is provided. | 03-04-2010 |
20100187160 | METHOD FOR PURIFYING MINERAL OIL FRACTIONS AND DEVICE SUITABLE FOR CONDUCTING SAID METHOD - Disclosed is a method for reducing the organic sulfur content in a sulfur-containing liquid fuel, wherein the sulfur-containing fuel is first brought in contact with a hydrogen-containing gas in a presaturator and subsequently the hydrogen-enriched liquid fuel is brought in contact with a suitable adsorbent in a reactor. The adsorbent is able to adsorb at least part of the sulfur and/or of the sulfur compound from the fuel at the surface. The contact with the adsorbent can advantageously take place not only at higher temperatures of approximately 400° C., but also at moderate temperatures, as low as room temperature, because the use of liquid fuel ensures very good contact between the fuel and the surface of the adsorbent, and therefore ensures reduction of the sulfur content. | 07-29-2010 |

20090036019 | Apparatus Useful as a Toy, Puzzle or as an Educational Device - An apparatus useful as an educational device, puzzle or toy of a kind having magnetic interactions between an elongate support and pieces held, or to be held, with or without contact, about said support, wherein a plurality of said pieces collectively form, or can form, a first band of pieces about said support, and another plurality of said pieces form, or can form, a second band of pieces about the support, and wherein at least one piece of each said band has an indicia, said indicia of a piece in one band being able to be indexed to an indicia of a piece of the other band, and wherein at least one of the bands of pieces is able, or will be able, to be rotated about the elongate axis of the support. | 02-05-2009 |
20100308536 | Three-dimensional puzzle or puzzle or display platform - The invention relates to a three-dimensional puzzle or puzzle or display platform being substantially spherical and having a substantially tessellated surface defined by substantially square form areas (first playing piece) and substantially triangular form areas (second playing piece), and having at least two parallel planes of demarcation on each of the three Cartesian axis that define said areas of said surface, and wherein the chord length of both said square form areas and said triangular said form areas are substantially similar. Said puzzle or game platform may be in conjunction with a levitator. | 12-09-2010 |
20140024283 | Toy Construction System - A toy construction system comprising a releasably connectable tendon or tether (“tendon”) to connect to at least two building blocks. The tendon being resiliently deformable and providing a range of motion for each of at least two blocks, relative to each other, in at least two Cartesian axes. The tendon having an engagement, and each block having a corresponding receiving element. | 01-23-2014 |
20140300050 | Three-Dimensional Puzzle or Display Platform - A three-dimensional platform comprising a tessellated surface of pieces, each piece comprising a top and sides. The pieces comprise a fixed square piece having at least two opposing sides orientated acutely relative to the top to define a fixed square retention surface. The remaining surfaces orientate substantially perpendicular relative to the top. There is a mobile square piece having at least two opposing sides orientated obtusely relative to the top to define a mobile square retention surface. The remaining surfaces are oriented substantially perpendicular relative to the top. A mobile triangular piece having all sides orientated obtusely relative to the top. The fixed square retention surface indexes only with either the mobile square retention surface or the triangular piece surface to effect retention of the pieces to define the three-dimensional platform. | 10-09-2014 |
