Abstract: In a harvester for grass crops and of the type comprising a supporting structure (1,2) in connection with ground wheels (3), cutter means (4) for cutting the crop and a conveyor and conditioner unit (5) for the cut crop, a double windrow is obtained by means of a side discharger having a roller conveyor (14) arranged behind the conveyor and conditioner unit (5) for lateral conveyance of the crop to a discharge opening (21) positioned rearwardly of the ground wheels (3) at one side of the mower. The roller conveyor (14) has a number of rollers (15-20) rotating in the same direction of rotation and which are disposed side by side with mutually parallel axes of rotation and with their one end facing the conditioner unit (5) while the rollers (15-20) at their opposite ends are journalled in a common retainer member (12). 
     The side discharger may be movable between an operating position active for side discharge and an inactive position in which the roller conveyor (14) is positioned outside a crop conveying path between the conditioner unit (5) and a discharge opening rearwardly directed from the harvester. The roller (20) of the conveyor (14) positioned closest to the lateral discharge opening (21) may have a larger diameter and may for instance rotate at a higher velocity than the remaining rollers (15-19), thereby further allowing use of the side discharger for crop scattering.

Abstract: In a process for coating the impeller blades of a rotating heat engine, the said blades are subjected in the operating state of the engine, i.e. "on line", to a first cleaning process, the appropriate agent for this, which depends on whether the blades are uncoated or coated, being mixed in the air stream to the compressor. After switching off the engine and opening it, the impeller blades are subjected in the stationary state, that is in the bladed state of the corresponding rotor or stator, to a preparation process for the following treatment stage. This preparation process may, for example, comprise, if required, dipping the blades into an oscillating erosive bath. The actual coating of the blades is performed by means of a high-speed flame spraying process, in which the protective layer is sprayed onto the surface of the base material at a particle speed of at least 300 m/s. After this, the blades are also subjected to a post-treatment, which if required serves to reduce the surface roughness and/or is provided for applying a top layer. <IMAGE>

Abstract: The present invention discloses an improved methodology for achieving the desirable feature of recirculation flow control in a sparger-type natural-circulation BWR, enabling reactors utilizing the method to perform in load-following and/or spectral shift modes of power operations. In its broadest aspects, the invention is based on locating the feedwater sparger (16) at an elevational level which is about water level (44) established during normal operation of the BWR. One or more of load following or spectral shift can be performed by controlling the feedwater fed to said BWR through the feedwater inlet and into the sparger to vary the water level to be above, at, or below the elevational level of such sparger.
