  • Patent number: 4667769
    Abstract: To reduce the speed of air being sucked towards a compressor turbine wheel, typically an exhaust gas supercharger turbine for an internal combustion engine, guide vanes (18) are located in the path of air being supplied to an inlet (3) of the compressor (1) which are positioned to impart a rotating component of motion to the air stream of air column being supplied to the compressor, the guide vanes extending essentially perpendicularly to the plane of radially positioned damping elements (14), while being inclined with respect to a radial line (19) passing through the axis of rotation of the compressor and, typically, of the housing (8) which has an air-pervious circumferential wall (8). The speed of air being supplied to the turbine thus can be reduced below Mach 1, thereby increasing the efficiency of operation of the turbine while substantially reducing its noise level.

  • Patent number: 4310031
    Abstract: Apparatus is provided for laying out and evenly distributing the coils of severed hot strands of wire emerging from a rolling mill. In order to maintain the line in continuous operation and in order to distribute the severed cooled strands to the subsequent bundling apparatus, the arrangement herein provides for dual conveyors each preceded by its own laying tube and a switch for selectively feeding the strands to one or other of the conveyors. By controlling the speed of one relative to the other of the dual conveyors, the strands may be selectively converged in even distribution for subsequent processing. The dual conveyors may be side by side or superimposed one above the other. With the latter arrangement, the upper conveyor may be mounted to pivot into and out of the line of the lower conveyor for the sequential feeding of the coils to the following line.

  • Patent number: 4023667
    Abstract: The invention covers apparatus for unstacking bar-shaped flat steel material which is transported stacked on a rake cooling bed having stationary and mobile rakes, in which the broad flat sides of the material rest on the rake flanks which are declining or sloped downward with respect to the direction of movement, and in which the side edges of the material rest on the inclined rake flanks which are rising or sloped upward with respect to the direction of movement.
