摘要： The invention relates to a heat generator for well stimulation, comprising a tubular fuel vessel (22) with two or more mutually separated, closed segments (23) arranged in longitudinal succession and each at least partly filled with fuel (30), and at least one igniter (40) for ignition of the fuel in at least one of the segments (23), wherein the ends of the segments are connected such that the fuel in a subsequent segment is ignitable owing to the evolution of heat in the course of burnoff of the fuel in a preceding segment. The invention further relates to a process for well stimulation using an inventive heat generator.

摘要： A grooved rail switch with a tongue rail device includes a tongue rail displaceably supported on a torsion-stiff support box for movement between a stock rail and a switch rail. The support box is made up of an upper slide plate, a lower bottom plate and flat bars extending between and welded to the slide plate and bottom plate. High strength bolts secure the stock rail to one side of the support box and the switch rail to the other side.

摘要： A process for the aluminothermic welding of rails in which the rail ends to be joined are surrounded by a prefabricated, dry refractory casting mold and sealed from the rails with plastic mold materials, such as, moistened sand; a reaction crucible is arranged above the casting mold and filled with an aluminothermic reaction mixture; the rail ends are preheated, for example, by burning a mixture of propane and oxygen and directing the flames downwardly into the riser-duct of the casting mold for a period of time up to about 2 minutes and at a temperature between about 300.degree. C and about 700.degree.C; the aluminothermic reaction mixture in the reaction crucible is ignited; and, upon completion of the reaction of the aluminothermic reaction mixture, the lower outlet of the reaction crucible is opened and the steel melt is poured into the mold.The amount of aluminothermically produced steel utilized is between about 0.15 and about 0.25 parts by weight based on the weight per meter of the rails to be welded.
