Abstract: The present invention relates to a SAR radar system, in particular with a wide antenna beam. By using a Local Backprojection SAR Processor the requirement for computational power becomes practical. The SAR radar system is arranged to collect signal amplitudes over segments of the vehicle track, called subapertures, which are so short that the closest points imaged on the ground are in the far-field of said subapertures with respect to a wavelength, characteristic of the radar signal, then to synthesize, from data obtained over each subaperture, a set of directive radar beams with an angular resolution determined by the subaperture length and the wavelength mentioned and each associated with a given position within the subaperture, to assume a topography for the ground surface, either based upon a topographical map or an assumption, for example that the ground is flat, and finally to compute the radar reflectivity of all ground points forming the image by a summation of the amplitudes for all subapertures at the range and beam direction determined by the platform position and the ground point.

Title: Molded plastic camshaft with metal seal ring
Inventor: IMMEL THOMAS A
IPC: F01L1/047
Filed: 1998-06-23
Abstract: An overhead camshaft internal combustion engine having a plastic camshaft which extends through an opening on the cylinder head, the plastic camshaft having a seal ring disposed around the outer surface of the molded plastic camshaft to provide an interface surface for contacting a seal assembly disposed between theengine casing and the molded plastic camshaft. The seal assembly and the seal ring provide a fluid tight seal to prevent leakage of fluid through the cylinder headopening. The seal ring provides a smooth contact surface for the molded plastic camshaft to prevent wear and damage to the seal assembly from the abrasive surface of the molded plastic camshaft. The seal ring also provides a heat sink for dissipating the frictional heat generated by the rotation of the camshaft.  In another form, the plastic camshaft includes a powdered metal surface formed thereon. Thepowdered metal surface provides the same benefits as the seal ring, namely protection from wear and dissipation of heat. The seal ring or the powdered metal surface may advantageously be extended to include the portion of the molded plastic camshaft in contact with a journal bearing.

Abstract: A workbench having multiple sections, each variable in width, connected together to form a work surface. A movable tool platform is located on each section, so that the platform is movable over the surface of the workbench section. A tool is mounted to each of the tool platforms, such that the tool is moved forward for working on a workpiece and backward to allow the front of the workbench to be used as a work surface. Thus, the workpiece is placed at the front of the workbench, and each tool needed for work on the workpiece is then moved, in turn, to the front of the workbench where it is used to perform work on the workpiece. The workbench can have a separation between the sections, to allow shavings and other waste material to fall below the work surface of the workbench and out of the way.

Abstract: A method is provided for roll-forming an I-beam structure having a web and a pair of opposing flanges at each end of the web. The method includes the steps of providing a flat blank having a thickness generally equal to a thickness of the web of the I-beam to be formed. The blank has a longitudinal axis, a central portion and opposing ends. Each of the blank ends is split along the longitudinal axis to form first and second flange portions at each of the ends. Each of the first and second flange portions has an edge directed away from the central portion. The flange portions are then bent about the longitudinal axis by moving each of the edges in a direction towards the central portion to form a mass of material at each of the blank ends. The mass of material is compacted at each of the blank ends to define the flanges. Each flange is disposed generally transverse with respect to the longitudinal axis and has a thickness generally equal to the thickness of the web.
