  • Patent number: 11999618
    Abstract: The technology relates to a method of producing synthesis gas comprising carbon monoxide (CO) and hydrogen (H2), wherein the synthesis gas is produced by a reduction reaction of a first flow comprising a carbon source and an excess of hydrogen in contact with an Oxy-flame. The hydrogen comes from a reducing stream, a first portion of which ends up in the first flow, and a second part of which is used to generate the Oxy-flame by combustion of the hydrogen in the presence of a second flow comprising oxygen (O2), the second flow coming from an oxidizing stream. The first flow and the second flow are at a distance from each other such that the Oxy-flame supports the reaction between the carbon source and the hydrogen. A reactor, which can have different configurations, is also proposed for implementing the method.

  • Patent number: 11978919
    Abstract: A battery safety vent assembly for a battery casing with an upper surrounding clamp-like shape is disclosed. The assembly has a positive cap, a safety vent disk extending under a disk element of the positive cap, a gasket insulator snugly fitting into the clamp-like shape of the battery casing and providing support to the positive cap, the safety vent disk and a circuit interrupt device embedded in an underside recess area of the gasket insulator. The circuit interrupt device is coupled to a button downwardly projecting from the safety vent disk. Gas release passages, openings and interfaces between parts of the assembly are arranged so that when gas pressure inside the battery casing exceeds a predetermined threshold limit of pressure, weak lines in the safety vent disk allow gas to safely exit the battery casing.

  • Patent number: 11926349
    Abstract: The invention relates to a vehicle displaceable along aerial conductors of an electricity transmission line. The vehicle includes a body having arms. Each arm has a first end pivotably mounted to the body and a second distal end. A motorized wheel is mounted to each arm to engage one of the conductors to displace the vehicle. Support rotors have at least two blades. Each blade has an arm portion extending from the support rotor and a contact portion extending from the arm portion to engage one of the conductors to temporarily support the vehicle. An arm displacement mechanism engages the arms, and is operable to displace the arms in a direction transverse to a direction of travel of the vehicle to move the arms together and apart.

  • Patent number: 11928398
    Abstract: The disclosed method reconstructs a topology of an electrical distribution network. An ohmic matrix model is generated as a function of consumption measurements provided by smart meters in the network. A tree table of nodes to which the smart meters are connected is defined. A branch in exploration is defined in the table and the nodes of the branch meeting preestablished relations are entered in the table as a function of connection values derived from resistive quantities in the matrix model. One of the relations determines a junction of the branch in exploration with a branch already explored connectable to a root to which a distribution transformer of the distribution network is connected. The topology is reconstructed by iteratively proceeding with sequences of decreasing values derived from the resistive quantities.
