A composite rim for a bicycle wheel that has a wall of structural fibers incorporated in a thermosetting polymeric material and a plurality of spoke attachment seats. The composite material includes at least one layer of woven bi-directional fibers where some fibers are in a nominal direction substantially parallel to the circumferential direction of the rim and some fibers are substantially orthogonal to the circumferential direction of the rim.

The present invention relates to a method for automatically uncovering a branch of a pipe system that is renovated with a lining tube, comprising the following steps, in particular in this sequence: a) providing an uncovering device, including a data processing unit, in the renovated pipe and arranging the uncovering device in front of the branch to be uncovered; b) inputting by means of an input unit a geometric shape to be uncovered; c) uncovering the branch by means of automatic milling, controlled by the data processing unit, of sections of the lining tube along the input geometric shape, using an uncovering unit of the uncovering device.

A blow-molding plastic bubble-generating device is provided, including a board-like shell body. The board-like shell body is formed through blowing a hollow embryo placed in a mold, the hollow embryo is blown and expanded, the hollow embryo is penetrated through by a plurality of needle posts on an inner wall of the mold to form the board-like shell body, the board-like shell body is integrally formed and hollow and has a shell wall which completely and continuously surrounds the board-like shell body, and the shell wall has a plurality of through holes.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

A crystallized bioabsorbable polymer scaffold comprises a polymer composition of poly (L-lactide-co-tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co-?-caprolactone) or poly (D-lactide-co-?-caprolactone) in the form of block copolymers of blocky copolymers, wherein the scaffold is cold-bendable. A crystallized bioabsorbable polymer scaffold comprising a polymer composition of poly (L-lactide-co-tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co-?-caprolactone) or poly (D-lactide-co-?-caprolactone) in the form of block copolymers of blocky copolymers, wherein the scaffold crystallizes in response to orthogonal strain.

An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosynthetic reinforcement.

A cell observation container includes a first container configured to accommodate a culture solution, and a second container having one or more wells that are able to be put in and taken out of the first container while retaining one or both of cells and cell masses cultured in the culture solution. One or more wells each include a bottom portion that is able to retain the culture solution, and a side wall that extends from a peripheral portion of the bottom portion. A liquid passage portion through which the culture solution accommodated in the first container is able to pass is provided in the side wall.

A method for producing a component having locally different thicknesses includes the steps of providing a first laminate, arranging a release layer on the first laminate, providing a second laminate with a second surface correlating with the first surface of the first laminate, placing the second laminate with the second surface on the first surface so that the release section is enclosed, joining the first with the second laminate by heating and/or pressing, guiding a cutting tool along one release section correlating with the release section, and so that the separating section is included, joining the first to the second laminate by heating and/or pressing, guiding a cutting tool along one contour in the second laminate that correlates with the separating section, so that one segment of the second laminate is completely detached, and removing the detached segment so that a recess is formed in each case.

An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosynthetic reinforcement.
