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.

The attachment feature includes a staple receiving portion including two ends, each of which has a staple retaining end disposed adjacent thereto. The staple receiving portion is configured to receive surgical staples, and the staple retaining ends are configured to inhibit the staple receiving portion from dislodging from the surgical staples.

An unconventional bolt includes a main body having two heads, and two threaded rods respectively formed at the external surface of each head coaxially with the main body, wherein the cross section of each head has a noncircular shape, and the axial projection of the cross section of the middle of the main body is located in the noncircular axial projection of each head of the main body. The unconventional bolt has a simple structure and a convenient assembly, and can improve the strength and rigidity of the nested profiled components after the connection; and the fastening device using the unconventional bolt can not only support the component but also reinforce it, thus effectively preventing the nested profiled components from transforming.

A thruster pig for sending through a pipe from an entrance facility to a receiving location, for servicing or monitoring, by pumping a thrusting fluid into the pipe to force the pig forward is disclosed. The thruster pig includes a body having a front end and a back end, where the back end includes a reaction surface to which said the thrusting fluid applies a motive force. The body is slightly smaller in diameter than the inner diameter of the pipe. The pig also includes a seal circumferentially arranged on the pig to seal between said body and said pipe. A desired differential pressure is maintained over the pig to urge said pig forward through the pipe by pumping a fluid into the annulus between the pipe and the return flow line while returning fluid through said return flow line utilizing connected servicing or monitoring equipment. A connector releasably connects a return flow line to the pig. The connector includes a shifting mandrel that may be activated to open the connector by a ball pumped through the return flow line, where the ball is retained in the return flow line after releasing the connector. A blanking device is then provided to blank the bore within the pig that is left after the return flow line is disconnected.

A manually operated floor grooving tool is provided which has opposing front and rear ends with a seam-following roller at its front end and a groove-following roller at its rear end. The tool also employs a pair of grooving blades, one at the front end and one at the rear end. The front grooving blade is inclined upwardly and rearwardly with its cutting tip located just behind the forward axis of rotation of the seam-following guide. The rear-end grooving blade, on the other hand, projects rearwardly from the rear end of the tool and is inclined upwardly and forwardly and behind the groove-following roller. Since the rear-end grooving blade projects beyond the end of the tool in which it is secured, it can complete the formation of the groove all the way up to a vertical abutment. The groove is thereafter filled with sealant in a conventional manner.

A watering mat is provided for the large-area distribution of water, particularly in horticulture and landscaping as well as agriculture. The watering mat includes a first and a second carrier layer to accommodate other elements of the watering mat, one or more connections for connecting the first and the second carrier layers, one or more water-feeding elements arranged between the first and the second carrier layers for feeding water into the watering mat and distributing water through the watering mat, an absorption layer for water storage arranged between the first and the second carrier layers and a moisture level detector in the watering mat.

A document formed of a stack of papers bound at the spine is equipped with a slide bar that achieves locking engagement with a document cover formed of a plurality of sheets of material. The sheets of document cover material are joined to each other at a binding margin. The sheet of cover material that passes around the spine of the cover forms a back cover beneath the stack of papers and a narrow, margin panel or strip that overlies the adjacent edge of the other sheet of binding material, which forms a front cover. The slide bar has a pair of jaws that terminate in distal tips that face each other at an angle of least forty-five degrees across a gap defined between the distal tips of the jaws. The slide bar is inserted onto the binding edge of the stack of papers and the cover encompassing them in a direction parallel to the binding edge from either the top or bottom end of the stack. The narrow margin panel atop the binding edge margin or the stack of papers fits within and is captured by the distal tip of one of the clasp jaws adjacent thereto throughout its length and throughout the length of the binding edge of the stack of papers. The capture of the narrow binding margin panel by the distal tip of the clasp jaw engaged at the junction between the sheets of the material forming the binder prevents the slide bar from being pulled laterally off of the binding edge of the stack.

A method and apparatus for capping and encapsulating a shaped wooden workpiece or substrate to protect against environmental elements and prevent splintering of the wooden substrate in the installed condition is disclosed. An inventive end cap having a melt ring integrally formed therewith is installed on a portion of the substrate, such as a terminus of the substrate. According to the invention, the wooden substrate is sheathed during a polymeric extrusion process with a substantially continuous, unbroken polyethylene or other polymeric layer extending from and continuous with the inventive end cap. During the extrusion process, the melt ring integrally formed along the annular walls of the end cap melt the encapsulant and form a substantially sealed configuration with the polymeric layer applied to the substrate. The melt ring is engineered to sealingly incorporate with the polymeric extrusion as the molten encapsulant is applied to the wooden substrate, to provide a substantially uniform sealed joint between the end cap and the polymeric layer while maintaining a substantially uniform cross-section along the length of the wooden substrate following completion of the encapsulation process.

A thruster pig for sending through a pipe from an entrance facility to a receiving location, for servicing or monitoring, by pumping a thrusting fluid into the pipe to force the pig forward is disclosed. The thruster pig includes a body having a front end and a back end, where the back end includes a reaction surface to which said the thrusting fluid applies a motive force. The body is slightly smaller in diameter than the inner diameter of the pipe. The pig also includes a seal circumferentially arranged on the pig to seal between said body and said pipe. A desired differential pressure is maintained over the pig to urge said pig forward through the pipe by pumping a fluid into the annulus between the pipe and the return flow line while returning fluid through said return flow line utilizing connected servicing or monitoring equipment. A connector releasably connects a return flow line to the pig. The connector includes a shifting mandrel that may be activated to open the connector by a ball pumped through the return flow line, where the ball is retained in the return flow line after releasing the connector. A blanking device is then provided to blank the bore within the pig that is left after the return flow line is disconnected.
