摘要:
A method for the preparation of corrosion-resistant and decorative coatings and layer systems for substrates of metals, preferably light metals. Also, method for the production of a coating and a layer system for substrates of metal, with which a decorative and corrosion-resistant, heavy-duty surface can be produced, including applying an adhesion layer (e.g., by chromatization) and a lacquer layer and a plasma etching process for the pre-treatment and improved adhesion of the subsequent layers, or PVD layers from oxides or metals. Providing PVD layers of a metal or metal alloys, and copper, nickel chromium which are chiefly galvanically applied are also preferably included.

摘要:
A method and an apparatus for forming a structure on a component made of a material composed of silicon oxide, especially of silicate glass, glass ceramic or quartz, wherein in accordance with the process at least a first surface of the component a partial removal of the material by plasma etching takes place and during the plasma etching at least at the surface to be etched a substrate temperature is established which is substantially greater than 90° C. but less than the softening temperature of the material. The apparatus is equipped for this purpose with a heater for generating the substrate temperature.

An automotive combine has a frame adapted to move in a travel direction along the ground, a front housing pivotal on the frame, a cutter on the front housing for cutting standing crop, and a main thresher on the front housing having a front intake and a rear output for taking in the cut standing crop at the intake, threshing it, and ejecting it at the output as a chaff/grain stream and a separate chaff stream. A pair of separate conveyors on the frame each have an intake at the rear output for receiving the chaff/grain stream and a respective output for ejecting respective portions of the chaff/grain stream. One of the conveyor outputs is vertically spaced above the other conveyor output. An upper sieve at the one conveyor output and a separate lower sieve at the other conveyor output receive the respective portions of the chaff/grain stream and separate kernels from chaff therein. The kernels are moved from the sieves to a grain bin on the frame while the chaff is blown out onto the ground outside the combine.

A winnowing blower for discharging a stream of air over the sieve of a combine harvester-thresher has an axially elongated housing formed at each of its axial ends with an inlet opening provided with an axial-flow fan. A shaft passing axially through the housing carries these two fans and two deflector disks spaced inwardly from the fans and each of a diameter substantially less than the respective fan. The housing is provided with a radially extending plenum chamber so that air drawn axially into the ends of the housing is partially deflected by these plates and ejected outwardly through the plenum chamber over the sieve of the combine.
