126results about How to "Increased pull-out strength" patented technology

Composite system, method for its manufacture, and measurement pickup using such a composite system

A composite system includes a first component, for instance of metal, and a second component extending at least partly through the first component along an imaginary longitudinal axis of the composite system. The second component contacts, with an at least partially curved, especially cylindrical, outer surface, an inner surface of the first component flushly such that the first component at least sectionally, at least partly, grips around the second component. Joining surfaces of the composite system, which are formed by the mutually contacting surfaces of the two components, are formed in such a manner that the two components exhibit contour portions in the area of these joining surfaces embodied as self-closing, peripheral surfaces. The contour portions fit at least partly into one another, to form a mechanical interference locking effective, at least in part, likewise in the direction of the longitudinal axis. Additionally, the second component, with its outer surface, contacts the inner surface of the first component flushly, such that the two components are mechanically tightly connected together also by means of a frictional locking effective at least partly in the direction of the longitudinal axis. Alternatively, or in supplementation thereof, at least one of the components is subjected at least partly to lastingly elastic, especially mixed plastic-elastic, deformations. The composite system is distinguished by a high pull-out strength, even in the presence of repeatedly arising vibrations in one of the components and is, therefore, especially suited also for use in a vibration-type measurement pickup.

Implantable prosthesis

A prosthetic device including biologically compatible and preferably fully resorbable materials includes a tissue infiltratable portion and a second portion. The two portion may have different rates of resorption. The ingrowth portion may include a plurality of openings to encourage tissue ingrowth and vascularization. The second portion may be stronger than the ingrowth portion and provide a location for fixation of the device. The portion may be attached using resorbable adhesives, sutures or other constructs to render a fully resorbable prosthesis.

Ovalized concrete block-out tube with tear away nailing flange

A block-out tube for use in joining together pre-cast concrete members, the block-out tube having an ovalized cross-section, an integral elongate imperforate hollow tubular body with smoothly curved corrugated walls, a rounded tip closing the bottom end thereof, a mounting flange with tear-away nail tabs at the top open end thereof, and a removable transparent member for sealing the top end for preventing water and debris from entering the interior of the tube. The block-out tube, secured by attaching the tear-away tabs to a concrete pouring form, is cast into the top of the lower concrete member, the ovalized corrugated body being embedded therein and the top sealed end being exposed at the top surface thereof, after the removal of the form. When the concrete members are erected and joined, the transparent sealing means at the top end is removed, the block-out tube is filled with grout, and a structural rod extending outwardly from one member is fitted into the grout-filled tube as the one member is joined to the other member, the grout engaging the structural rod and the corrugated tube wall, forming a strong joint between the two concrete members.
