  • Publication number: 20240347030
    Abstract: A solid body structure may be connected to or support a structure-borne sound source. The solid body structure may have two structure-borne sound wave impact edges which extend in a direction of structure-borne sound wave propagation. The impact edges may, for example, approach one another and/or may be convex at least in sections in the direction of the structure-borne sound wave propagation.

  • Patent number: 10451392
    Abstract: Tracer ammunition for tracking the trajectory and/or the impact of projectiles in the target generally contains pyrotechnics. These pyrotechnics demonstrate various disadvantages, wherein the most serious is the continued burning of the pyrotechnics, even after penetration of the projectile in the target. This causes an increased risk of fire and acute injuries. A mixture of light metal and a carbon-containing substrate, ignites during firing of a projectile and burns during its flight by means of air oxygen introduced into the combustion chamber by way of tear-off edges, and produces a tracer that extinguishes in the target.

  • Publication number: 20050154337
    Abstract: A thoraco-lumbar spine support/brace for correcting lateral spinal alignment. The brace comprises a frame member defined by two elongate bracing rods extending vertically in generally parallel relation to one another on opposed sides of the body of the wearer that extend generally from the wearer's shoulders to pelvis. Extending across the uppermost ends of the bracing rods is a posterior traction belt. At least two anterior traction slings are provided that extend across an intermediate portion of the bracing rods. A pelvic arch is further provided that extends across the bottom-most ends of the opposed bracing rod members. The posterior traction belt, anterior traction slings and pelvic arch may all be selectively positioned to impart a desired physiological orientation of the waerer's spine, and can be utilized to treat a given condition such as abnormal thoracic kyphosis, pelvic inclination and lumbar lordosis.
