  • Patent number: 4746571
    Abstract: An X-ray detector efficiency standard is formed of multiple spherical particles of various materials distributed over the surface of a substrate. The particles are preferably formed of pure materials, such as pure elements and stoichiometric compounds, having characteristic X-ray emission energies which span a range sufficient to determine the efficiency of the X-ray detector substantially over its operating range. The spherical particles may be formed by an electrohydrodynamic spraying process and have a diameter preferably in the range of 10 nanometers to 1 micron.

  • Patent number: 4731280
    Abstract: The ribbed article has ribs which are built-up of multi-layer ribs. In the crossing points or overlap zones, some of the weld seams of one rib are continuous or discontinuous while the weld seams of the crossing rib are discontinuous or continuous as the case may be. The overall height of the overlap zone is the same as the ribs forming the overlap zone. A pair of guide beads are also applied to the base member prior to application of the first weld layer of a rib in order to guide the build-up of a rib.

  • Patent number: 4721645
    Abstract: Radially extending fibers are disposed over a conical surface at predetermined sites. The sites correspond to vertices of a pattern of contiguous congruent isosceles triangles inscribed onto the surface of a sector of a circle which may be conformally mapped onto the conical surface so that vertices of the pattern coincide along the join line meridian of the conical surface. Fibers are disposed between the radially extending fibers in three different directions which respectively correspond with the sides of the triangles. The material obtained exhibits an invariant fiber volume fraction along the axis of the conical surface. The material may be used to reinforce a conical object. Also, an object, such as a preform, having a conical surface and method for reinforcing an object having a conical surface, in accordance with the present invention, are described.

  • Patent number: 4716075
    Abstract: A culvert having a corrosion resistant composite coating and a method of producing the corrosion resistant composite coating. The coating method is for use in a conventional hot dip coating line of the type wherein a steel strip, having been appropriately pretreated so as to be at or above the coating temperature and have its surface free of oxides, is caused to pass through a bath of molten coating metal. A fibrous aramid paper is bonded to the surface of the steel strip by pressing the fibers into the molten coating layer immediately after the steel strip exits the coating bath. The steel strip may be fabricted into construction products such as culvert which may be further protected with bituminous type coatings.

  • Patent number: 4160058
    Abstract: A waterproof covering is manufactured by depositing a fluid product, forming an adhering and watertight film, on the surface of the basis or support to be waterproofed. A textile layer is laid on the film before its complete formation, i.e., while a portion of the film forming fluid is still in its fluid state, in such a way that the central portion of this layer is not impregnated and a second fluid forming an elastic waterproof film is laid on the textile in such a way that the central portion of the textile layer is not impregnated. The roll of material used in this process is also disclosed as well as is thewaterproof covering obtained by this process and its use to waterproof terraces, front walls, foundation walls, tanks or the like.
