Norbert Lahme has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20030175203
    Abstract: The invention relates to a method for rapidly curing positive lead accumulator plates. According to said method, the plates are separated and treated with water vapour for a period of less than 3 hours. The method is characterised in that the curing takes place at environmental temperatures of above 60° C. and that the type of lead sulphates that form during the curing process is controlled. To achieve this for example, finely crystalline tetrabasic lead sulphates are formed by the addition of seed crystals and the formation of tetrabasic lead sulphates is prevented by the addition of an expander. The invention enables the entire curing process to be reduced in an advantageous manner to approximately 4 h, thus improving the cost-effectiveness of the method.

  • Publication number: 20030140469
    Abstract: A device for manufacturing lead plates for a lead/acid battery, wherein lead electrode grates are filled with an active paste to form green lead plates to be cured, has at least three climate-controlled, connected chambers for curing the green lead plates. An inlet for introducing the green lead plates into a first one of the climate-controlled chambers is provided. The device has a transport device for moving the lead plates through the at least three climate-controlled chambers for curing. A removal device for removing the cured lead plates is provided. A control device controls temperature, humidity, and air movement in the at least three climate-controlled chambers.

  • Patent number: 6488982
    Abstract: A method for reducing ion concentrations in separator materials used in electrochemical processes, including in lead storage batteries. The separator material is treated with at least one acid from the group of sulphuric acid, phosphoric acid and sulfonic acids and/or at least one salt from the group of sulfates, phosphates and diphosphates of the alkali metals of alkaline earth metals.

  • Patent number: 6254841
    Abstract: For an improved recombination system serving to catalytically recombine hydrogen and oxygen, which form in a storage battery, into water and incorporating an adapter union assembly for the gas-tight connection of the system to a storage battery, a container which is gas-impermeable to the outside and which houses a recombination assembly, as well as a conduit for the loss-less gas intake from the adapter union to the container and water return flow in the opposite direction, whereby even in the event of an overload the hazard of escaping gas can be avoided and the efficacy of the catalytic unit can be maintained while at the same time the system can be produced at low cost and in a way as to be easily assembled and maintenance-free, this invention proposes to provide next to the conduit an expansion section which is open toward the outside but delimited by an ignition suppressor, and to connect the conduit with the expansion section by way of a gating aperture.

  • Patent number: 6114066
    Abstract: A method and apparatus for producing lead storage batteries are provided. sentially grid-shaped lead electrodes are produced and are provided with a pasty, active mass. Immediately thereafter separator material is provided on both sides of the electrodes. The electrodes are stacked, electrically connected, and placed in a housing to form a cell unit, which is subsequently stored to effect curing of the pasty, active mass.

  • Patent number: 6014798
    Abstract: A method for manufacturing lead plates for a lead/acid battery includes the step of providing lead electrode grates and filling an active paste into the lead electrode grates to form filled lead plates. Subsequently the lateral surfaces of the filled lead plates are subjected to a continuous processing sequence of less than 6 hours under preselected processing parameters for time, temperature, humidity, and air movement. The processing sequence includes a curing step in which moisture is added to reach a first humidity value, a predrying step for reducing the amount of free lead in the active paste at a second humidity value that is lower than the first humidity value, and a final drying step.

  • Patent number: 4129687
    Abstract: A reaction catalyst for the recombination of the oxyhydrogen gas produced by lead-acid storage batteries into water in a controlled, exothermic reaction, where the catalyst element is a solid rod element with a central heat conducting core, the catalyst rod being positioned inside a gas-tight housing in communication with the battery gas space. This rod element is produced by a fabricating method in which granular catalyst carrier material is worked into a paste which is then shaped and dried, the metallic catalyst being deposited on the surface of the carrier grains.
