The screw flight has a cross-sectional profile with a width in the region of the outer circumference of the screw flight greater than the width in the region of the inner circumference of the screw flight. Furthermore, the invention relates to a separator device for dewatering moist masses, including liquid manure residues and/or digestates, as well as a method for additively manufacturing a screw conveyor and a use of a screw conveyor.

A method for creating an electric heating source, including a body equipped with one or more housings containing mineral-insulated heating cables. The housings communicate with one or more reservoirs which accept a purely metallic solder material in solid, powder or sheet form. The device is heated in a vacuum degassing plateau, followed by a casting plateau during which the solder melts and fills the housing around the heating cables, resulting in full metal contact between the cables and the body, providing a more uniform temperature and a shorter response time to heating or cooling. Also, a heating source obtained in this manner, including an infrared faired source or an immersion heater for the heating of a liquid bath of molten metal.

A disc cutter for a cutting unit used in a tunnel boring machine and a method of producing the same. The disc cutter includes an annular disc body made of a metal alloy or metal matrix composite having a first side, a second side arranged substantially opposite to the first side and a radially peripheral part. At least one metal alloy, metal matrix composite or cemented carbide cutting part is mounted in and substantially encircling the radially peripheral part of the disc body, which protrudes outwardly therefrom to engage with the rock during the mining operation. The at least one cutting part is made from a material having a higher wear resistance than the material used for the disc body. A metallic interlayer is disposed between at the least one disc body and the at least one cutting part, the elements of which form the diffusion bonds.

An insert tool, in particular a drilling tool, having a base module is disclosed. The base module has a first portion, which in particular includes a conveying helix, and a second portion, which includes cutting bodies with preferably at least two rake faces. The second portion is connected to a first end of the first portion in an integrally bonded manner. The base module is connected, at a second end, to an, in particular hardened, insertion end in an integrally bonded manner by way of in particular a friction welding method.

A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.
