Abstract: A method and a device for injecting a fluid into a layer of rock or earth, such as a crude oil-containing layer of rock or earth, for example, for the tertiary crude oil production by means of a suitable line, wherein the line is introduced into the layer of rock or earth. The line consists of an inner pipe and an outer pipe. The inner pipe is provided with injection nozzles. The injection nozzles are positioned and thus ensure a pressing of the fluid into the surrounding layer of rock or earth via the openings in the outer pipe in a positioned manner. Means which allow for a selective impacting of the individual injection nozzles, are located in the interior of the inner pipe. The fluid is pressed into the surrounding layer of rock or earth in a positioned manner.

Abstract: The invention describes a method for injecting a fluid into a crude oil-containing layer of rock or earth by means of a suitable line, wherein the line is introduced into the layer of rock or earth and the fluid is injected for the purpose of an enhanced crude oil production from the crude oil-containing layer of rock or earth.

Abstract: A process (10) for synthesising hydrocarbons includes feeding a gaseous feedstock (18) comprising hydrogen and carbon monoxide, into a first Fischer-Tropsch reaction stage (12) which is a three-phase low temperature catalytic Fischer-Tropsch reaction stage, and allowing the hydrogen and carbon monoxide partially to react catalytically in the first reaction stage (12) to form hydrocarbons. At least a portion of a tail gas (32) which includes unreacted hydrogen and carbon monoxide obtained from the first reaction stage, is fed into a second Fischer-Tropsch reaction stage (42) which is a two-phase high temperature catalytic Fischer-Tropsch reaction stage. The hydrogen and carbon monoxide are allowed at least partially to react catalytically in the second reaction stage (42) to form gaseous hydrocarbons.

Abstract: This invention provides an understanding of the structure and porosity of soil and stony regions. The method is characterized by release of a measuring gas in the region being investigated and its penetration through the investigated region to several places where it is captured and measured. Thus, the measured data from the various measuring locations provides the structure and the porosity of the region being investigated. The method is especially suited for the investigation of dams and the location of underground cavities and tectonic faults.

Abstract: A plate conveyor or moving walk, especially for transporting individuals, comprising plates or pallets arranged in succession in the direction of travel of the moving walk. These plates are connected with two essentially mutually parallely extending, endless drive chains. Traveling rolls enable the plate conveyor to revolve upon guide rails in one or a number of horizontal and/or inclined planes or portions. The drive chains are arranged along sides of the plates extending parallel to the direction of travel of the plate conveyor. Each chain link is connected by at least one attachment element with one of the plates.
