A device for curing resin in a pipe liner using electromagnetic radiation includes a heat sink and LEDs for generating the radiation mounted on the heat sink. The device conducts heat away from the LEDs through the heat sink. The heat sink is positioned in the flow path of cooling fluid that draws heat away by convection. The heat sink can include elements at the ends of the LEDs that are exposed to the cooling fluid. The device can guide the cooling fluid along a flow path that includes a segment that extends over the LEDs. The device can limit fluid flow through a central cavity of the heat sink.

A residential or commercial building, structure, or building component can include an exterior member, interior member, and plurality of cross-members spatially disposed therebetween. Each of the exterior member, interior member, cross-members can be formed from a multi-layered stack of polymeric material made by a layered three-dimensional printing process, and all can be monolithically integrated. An exterior surface region of the exterior member can have an integrally formed surface finish. Overlying finishing or connective layers can be added. The exterior and interior members can be configured in a parallel arrangement to form a rectangular or curve shaped building block. A fill material can be disposed into openings between the exterior and interior members, and an interior surface region at the interior member can include a cavity configured for an electrical box, plumbing, or a sensing device.

Methods, apparatus or equipment and systems for lining conduits, e.g., preferably subterranean pipelines and passageways, such as sewers, with a liner impregnated with a curable resin in order to secure the conduit against ingress or egress of liquids.

An object of the present invention is to provide a method of joining resin tubes, in which the degree of freedom of selecting a tube material is large, and further a defect such as stiffness and contraction at joining portions of the tubes is not developed. The method of joining resin tubes according to the present invention is a method of joining resin tubes so that a first tube is joined to a second tube, the first tube and the second tube each being made of synthetic resin, the method comprising: a surface activation step of activating each of a joining region of the first tube and a joining region of the second tube; and an adhesion step of adhering the joining region of the first tube obtained via the surface activation step with the joining region of the second tube obtained via the surface activation step to each other.

A method for making a three-dimensional laminated object, including: providing multiple sheet substrates each having an adhesive layer; consecutively stacking one of the sheet substrates onto a previous one of the sheet substrates on a work station, the previous one of the sheet substrates having been cut along and cured within a first contour; cutting the one of the sheet substrates along a second contour; and curing the adhesive layer of the one of the sheet substrates within the second contour to bind the one of and the previous one of the sheet substrates, where operations of the cutting and curing of the one of the sheet substrates at least partially overlap in time. An apparatus for making a three-dimensional laminated object is also provided.

A machine for gluing a ring-shaped workpiece prior to machining operations. The machine includes a support assembly adapted to receive a removable support element having a top surface for receiving a workpiece; a glue dispenser system adapted to apply a predefined amount of glue on a face of at least one of the workpiece and the support element; a gripper assembly for placing a workpiece on the support element; an illuminating system adapted to illuminate the applied glue with ultraviolet light, this illuminating system including: at least one inner lighting element for radially illuminating an inner radial face of the ring-shaped workpiece with ultraviolet light, and at least one outer lighting element for radially illuminating an outer radial face of the ring-shaped workpiece with ultraviolet light.

There is provided a joining structure of a resin member for a vehicle body and a stud bolt that can more strongly fix a stud bolt to a resin member for a vehicle body by an ultraviolet curable adhesive. Convex portions are provided at a portion, which structures a flange-adjacent portion, of a mounting surface portion of a resin member for mounting. Therefore, a surface area of adhesion with adhesive at a place, which is covered by a flange portion as seen in a plan view, of the mounting surface portion can be made to be large. As a result, adhesive force of a portion, which is cured by diffused ultraviolet rays, of the adhesive A that is covered by the flange portion as seen in a plan view can be made to be large.

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity. The cavity has a proximal portion that is adjacent the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

An edge trim for pieces of furniture, including a meltable layer, is described. The molecular structure of the meltable layer contains both polar and non-polar parts. By way of a non-limiting example, an edge trim for pieces of furniture having an exposed edge of wooden or wood substitute material is described, comprising a molten layer and a structural layer, wherein the structural layer and the molten layer are connected in an adhesive bond, wherein the molten layer is made of a material that is chemically modified such that polar and non-polar components are found in a single molecular structure, wherein the molten layer contains energy absorbing additives, wherein the energy absorbing additives of the molten layer are selected from the group consisting of metal oxides, metal phosphates, metal salts of organic anions and combinations thereof.
