Abstract: An angular position determining system utilizing an electronically scanned, linear phased array antenna radar system.  The teachings of the present invention are applicable to airborne, ground or sea based radar systems for determining either elevation of azimuth.  In one disclosed embodiment mounted in an aircraft for determining elevation, the linear phased array antenna is formed by a conformal wing array of radiating and receiving elements, wherein the phase front of the antenna beam can be controlled to steer the antenna beam by individually controlling the gain and phase excitation of each radiating element.  The array comprises a left portion of the array and a right portion of the array, and each of the left and right portions is formed by a first plurality of elements tilted downwardly in elevation and a second plurality of elements tilted upwardly in elevation. The output signals from the left upwardly tilted plurality of elements are summed to form an up left sum signal, and the output signals from the left downwardly tilted plurality of elements are summed to form a down left sum signal. Similarly, the output signals from the right upwardly tilted plurality of elements are summed to form an up right sum signal, and the output signals from the right downwardly tilted plurality of elements are summed to form a down right sum signal.  Additionally, the up left sum signal and the up right sum signal are summed to form a composite up sum signal and the down left sum signal and the down right sum signal are summed to form a composite down sum signal. Finally, the difference is taken between the composite up sum signal and the composite down sum signal to form a delta elevation signal representing the measured elevation output of the system.

Abstract: A centrifugal processing system and method introduces fluid to be processed into a centrifugation chamber,  while directing the  fluid away from the region of the chamber where the largest centrifugal (or "G")  forces exist.   The fluid is also conveyed into the force field as a generally uniform stream having reduced turbulence or being essentially free of turbulence. The system and method thereby establish, upon the entry of a high velocity fluid stream into the centrifugal field, non-turbulent and uniform flow conditions conducive to effective separation.   The system and method also direct the fluid in a way the maximizes  the  effective  surface  area  of  the centrifugation chamber  for  separation.    Effective separation can thereby be achieved at high inlet flow rates.

Abstract: ABSTRACT OF THE DISCLOSURE        A  process and apparatus for fabricating expandable honeycomb materials disclosed.   The continuous length of material is folded along opposite side portions thereof into a generally flat  tubular  form having  upper  lower  layers.          Adhesive is then applied along the length of the continuous material by first heating the material, applying the adhesive in a liquid state to the heated material, and then cooling the material  to solidify  the adhesive.   The folded tubular material with solified adhesive lines thereon is then wound about a rack in such a manner that the tubular material is deposited in a plurality of continuous layers one on another with the lines of adhesive being disposed between adjacent layers. The wound layers are then radially cut and placed in a vertically aligned stack while they are removed from the rack.          The  vertically stacked layers are then heated to a temperature sufficient to activate the lines of adhesive and bond the layers together.  Finally, the stacked tubular material is cooled to form a unitary  tack of tubular,  expandable honeycomb material.  A device for performing the process as described above is also disclosed.

Abstract: In a loading vehicle comprising a pick-up drum (21) with resilient fingers (23) for picking up straw or other crop material from the ground and a conveyor drum (26) with conveyors (27), fitted in rows, for carrying the material picked up into the vehicle, the pick-up drum and the conveyor drum are disposed with respect to each other so that the conveying direction of the material is abruptly changed when the material is introduced into the path of motion of the conveyors. This produces a damming-up effect causing the material to be distributed over the entire conveyor front, which minimizes the tendency of squeezing between conveyors and the housing wall defining the conveyor duct (34) at one side. The change in conveying direction also causes a certain compaction of the material, resulting in a better utilization of the available volume. The structure allows short spacing between the conveyors (27) and thus closely spaced knives in the conveyor duct so that the material e.g. blades of grass can be cut in small pieces which are suitable for ensilage.
