20140298653 | METHOD FOR MANUFACTURING TUBE PLATE FIN HEAT EXCHANGERS - Method for manufacturing tube fm heat exchangers, (TFP), by brazing metal components of mainly aluminium or aluminium alloys including the following steps:—making the components of the TFP heat exchanger including the tubes ( | 10-09-2014 |
20140069625 | METHOD AND EQUIPMENT FOR HEAT RECOVERY - The present invention relates to a method and equipment for recovering heat from exhaust gas removed from an industrial process, such as an electrolysis process for the production of aluminium. Heat is recovered by means of an extraction/suction system, where the exhaust gas contains dust and/or particles. The heat is recovered as the exhaust gas being brought into contact with heat-recovery elements. Flow conditions and the design of the heat recovery elements are such that the deposits of the dust and/or particles on the surfaces stated are kept at a stable, limited level. In preferred embodiments, the heat-recovery elements have a circular or an extended, elliptical cross-section and may be equipped with fins or ribs. | 03-13-2014 |
20130282175 | METHOD AND SYSTEM FOR HANDLING OBJECTS - The invention relates to a method and a system for handling long objects, in particular packing extruded profiles. It comprises two robots with one arm each, said arm having a pair of grippers, and a control unit that coordinates and controls the movement of the robots. In the handling operation the mutual distance between the two said pair of grippers are held constant, to counteract misalignment of the object. | 10-24-2013 |
20110221214 | IMPACT ABSORBING MEMBER AND A METHOD FOR MAKING SAME - A method for manufacturing an impact absorbing member, starting with a closed or substantially closed hollow section with a mid section and two end sections, wherein at least one the end sections is bent to form a supporting member, whereby at least one imprint is made in the part of the section to be deformed by the bending operation. The invention also relates to an improved impact absorbing member formed by a manufacturing process including bending. | 09-15-2011 |
20110099937 | Uninsulated section suitable for producing insulated sections for thermal break window and door frames and associated method of assembly - An uninsulated section comprising a first section element and a second section element is described; the first section element comprises a first cavity for housing a portion of a first heat-insulating body and a second cavity for housing a portion of a second heat-insulating body; the second section element comprises a third cavity for housing another portion of the first heat-insulating body and a fourth cavity for housing another portion of the second heat-insulating body. The uninsulated section also comprises a partition connecting the first section element and the second section element. Advantageously, the partition may be situated between the first and the second cavity and between the third and the fourth cavity. | 05-05-2011 |
20110094081 | Uninsulated section suitable for producing insulated sections for thermal break window and door frames and associated method of assembly - An uninsulated section comprising a first section element and a second section element is described; the first section element comprises a first cavity for housing a portion of a first heat-insulating body and a second cavity for housing a portion of a second heat-insulating body; the second section element comprises a third cavity for housing another portion of the first heat-insulating body and a fourth cavity for housing another portion of the second heat-insulating body. The uninsulated section also comprises a partition connecting the first section element and the second section element. Advantageously, the partition may be situated between the first and the second cavity and between the third and the fourth cavity. | 04-28-2011 |
20110048667 | ARRANGEMENT RELATED TO EQUIPMENT FOR CONTINUOUS OR SEMI-CONTINUOUS CASTING OF METAL - A device in connection with equipment for continuous or semi-continuous casting of metal, in particular direct mould (DC) casting of aluminium in the form of a billet or wire billet, comprising a mould with a cavity or mould ( | 03-03-2011 |
20100225107 | Gas Tight Tubular Joint or Connection - Gas tight tubular joint or connection, particularly related to mono diameter tubular body in the form of a pipe or casing being used in connection with the production of oil and/or gas, where the pipes or casings are manufactured from tubular sections and where the tubular sections, after being interconnected at their respective ends, are finally formed by expansion. The pipes or casings are formed from at least two, one outer and one inner tubular section. The ends of each of said respective section is overlapping the next, succeeding tubular section, whereby one or more of the inner, intermediate or outer tubular sections are of different metallic materials and/or different thickness, and under the deformation process, is plastified or plastically deformed in the overlapping zone forming a metallic seal and thereby providing gas pressure integrity between the inside and outside of the expanded tubular pipe/casing. | 09-09-2010 |
