Abstract: A downhole motor, having a body having an outside surface and a longitudinal extent, a first flow passage defined within the body and disposed along the longitudinal extent of the body, and a second flow passage extending from the first flow passage to a channel at the outside surface, wherein a Bernoulli suction force is created at the channel. A method for drilling a borehole, including directing a fluid through a first flow passage defined within a body of a drill and disposed along the longitudinal extent of the body, directing a portion of the fluid from the first flow passage through a second flow passage to a channel at an outside surface to create a Bernoulli suction force at the channel, and drilling a curved section of the borehole by using the Bernoulli suction force at the channel.

Abstract: A drilling system configured to drill a borehole into a subsurface formation, including a steering device. The steering device is configured to convey a fluid supply through a valve to an outside surface of the steering device, wherein the fluid flow causes a steering force on the steering device. A method for drilling a borehole into a subsurface formation, including disposing a steering device in the borehole, rotating the steering device, urging a fluid to flow through a valve of the steering device to an outside surface of the steering device, wherein the fluid flow causes a steering force on the steering device.

Abstract: A steering augmenter for a steering device of a drilling tool, including a body, a first flow passage in the body and configured to convey a fluid supply. a channel at the outside surface of the body, the channel being configured to produce a Bernoulli effect therein during fluid flow therein, a second flow passage fluidly connecting the first flow passage to the channel, and a valve associated with the second flow passage and configured to allow, prevent or choke flow through the second flow passage. A downhole drill bit assembly including a steering augmenter, the drill bit attached to the steering augmenter. A method for drilling a borehole into the earth, the method including conveying the steering device into the borehole, operating the valve to allow, prevent or choke flow through the second flow passage, creating a steering force at the steering augmenter by the produced Bernoulli effect.

Abstract: The subject matter of the present invention is a method for treating pourable products made of particles which can be separated, preferably seeds (2), with accelerated electrons. During the method, a transparent product flow is guided, using gravity, in a product guiding channel (1) through the electron field generated by at least one electron accelerator (12) under low pressure or excess pressure. The product flow is guided by means of an accelerated gas flow (5) in such a way that the movement thereof corresponds in magnitude and direction to the accelerated movement, which the falling particles execute in said gas flow due to gravitational acceleration. In addition, a device is disclosed which realizes the acceleration of the gas flow (5) in the required way through the shaping of the product guiding channel (1).

Abstract: Electron gun with band-shaped beams that includes a vacuum chamber extend in a longitudinal direction, a beam window running in the longitudinal direction along the vacuum chamber, and a cathode control-electrode system positioned within the vacuum chamber in the longitudinal direction. The cathode control-electrode system includes at least one substantially straight cathode positioned substantially parallel to a longitudinal axis of the cathode control-electrode system and the at least one substantially straight cathode has bulges formed at defined distances. The bulges are shaped to produce a substantially homogeneous current density distribution along the at least one substantially straight cathode and support units are located in the cathode control-electrode system to correspond with the bulges. The bulges are removably couplable to the support units.
