Abstract: SEPARATOR FOR AN AXIAL FLOW ROTARY COMBINE        Abstract of the Disclosure In an axial flow rotary separator for a combine, radially extending spike-tooth-like blades are arranged on a rotor body in "reverse" helical arrays, that is, such that helical flighting, similarly disposed, would tend to convey crop material upstream.  The helix angles defined by the arrays approximate that of the mean spiral path of conveyance of a crop material mat portion through the separator housing.  Propulsion of the crop material mat thus results from a plurality of spaced and staggered engagements of small contact area.  The rotor elements present no extensive wall or front to the crop material thus reducing the tendency to "roping" and separator plugging in tough straw conditions.

Abstract: - 1 -Abstract: This invention relates to a solid-state imaging apparatus wherein photo signals are read out through MOS type FETs from photosensors, such as photodiodes, arrayed in two dimensions in large numbers. The invention improves the signal-to-noise ratio of the output signal by reducing or eliminating noise components mixed in the photo signal. Analysis of the noise components has revealed a correlation in which a noise component of a certain polarity develops again with the opposite polarity after a period that is shorter than one horizontal scanning period by the duration of one horizontal scanning pulse. To take advantage of this correlation, the apparatus provides a processing circuit that includes a delay circuit and an adder circuit to act together to cancel the noise.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided for the reduction of the dark colouring of paper pulp in white water systems.  The process involves adding oxygen, or oxygen-containing gases  to the whitewater system of the pulping system. The oxygen is added in such an amount that aerobic conditions are maintained substantially permanently in at least a part of the whitewater system, and where the redox potential is higher than -100mV.  This seems to prevent anaerobic bacteria from forming metal sulfides on the pulp.

Abstract: NON-CONTACT SENSOR FOR DETERMINING MOVING FLAT STEEL STRIP SHAPE PROFILE       ABSTRACT OF THE DISCLOSURE Method and apparatus for monitoring the flatness characteristic of a moving electrically conducting strip of material by continuously measuring the change in capacitance between the strip surface and a fixed point adjacent the surface.  The capacitance is measured by means of a sensor (1) having an active plate (7) surrounded by a guard plate (2) for eliminating stray capacitance, both plates (2, 7) being impressed with a high frequency signal.  Changes in capacitance associated with both plates are eliminated while changes in capacitance associated with only the active plate are converted to a voltage proportional to the inverse of the spacing between the active plate and the strip surface. A plurality of the sensors (1) may be spaced across the width of the plate (7) for providing a profile of the strip flatness characteristics.  The sensor finds particular application for monitoring and characterizing bottom buckles in steel strip following high temperature annealing.
