Title: Axial flow rotary separator for a combine
IPC: A01F12/44
Filed: 1978-08-17
Abstract: In a rotary separator, cylindrical threshing, frusto-conical separating, and centrifugal fan sections are arranged coaxially and in tandem. A fixed grate including threshing and separating portions surrounds and generally conforms to a rotor profile. A frusto-conical collector housing encloses the forward part of the separator and feeds threshed and separated grain to a grain cleaning unit, the screen elements of which, along with the collector housing, rotate concentricaly with the grate while at the same time reciprocating axially. A stationary cylindrical housing surrounds the cleaner unit and clean grain and tailings pass centrifugally from the cleaner screens to separate annular channels, to be swept around the inside of the housing by paddles moving with the cleaner elements to tangential discharge points near the top of the separator for transfer to clean grain and tailings return augers respectively. The centrifugal fan draws air approximately axially through the cleaner unit removing chaff and other light material and also receives straw carried over the grate, for discharge downwards from the fan housing.
Patent ES-476079-A1 (ES)
Title: Device for mapping absorption distribution.
IPC: G01N23/04
Filed: 1978-12-16
Abstract: For determining the absorption distribution in a plane of a body by means of a fan of radiation beams from an approximately point-shaped radiation source and in different positions of the body with respect to the radiation source, a detector element comprising only one amplifier is used for a number of adjacent radiation beams or all radiation beams. For determining the intensity profile in each measuring position, the radiation beams are modulated by time functions which form a complete, linearly independent function system (Walsh functions). Modulation is realized by means of an aperture which is constructed as a rotating disc which comprises transmissive and non-transmissive sectors. At each change of a function value, a discrete signal value is derived from the detector signals, so that the total number of signal values equals the number of functions of the function system. The signal values are multiplied by a back transformation matrix and therefrom the intensity profile is recovered. This profile is processed in known manner in order to obtain an absorption image. This principles is also suitable for a two-dimensional fan of radiation beams for the simultaneous determination of the absorption distribution in a plurality of planes.
