Method of Carving Hollow Core Materials
20240351296 · 2024-10-24 ·

The premise of this invention is to improve the methods for allowing one to carve the surface of a hollow core panel or other hollow core materials, such as but not limited to Sing Core, U.S. Pat. No. 7,147,741. In the past, in order to achieve a shallow carving in the surface of the panel one would apply a thicker surface material, or skin material, greater than the depth of the desired carving. Skin materials can be any flat sheet building materials such as plywood, MDF, HPL, fiberglass, wood products, metals, or any other type of flat sheet building materials. Another previously used method is to implant solid lumber that is the same thickness of the core inside the panel. The skin materials can then be pressed over the core and lumber implants. That method works well, but the use of solid lumber creates a weak point across the panel and greatly increases the thermal bridging between each face of the panel.

This new method of carving hollow core materials begins as a hollow core panel before the skin materials are applied. The areas where the final carvings need to be can first be carved out of the core material. Core material can be any hollow core materials such as paper core, LVL core, foam core, honeycomb core such as Sing Core, or any other core materials. The groove or carved space in the core can then be filled with a solid piece or pieces of the same material as the skin material. The material filling the groove or carving in the core can be slightly thicker than the depth of the final carving depth. The material filling the groove can be coated in an adhesive of choice before placing the inlay material in the groove. Once the material is placed in the groove, skin material can be applied both faces of the panel with an adhesive of choice and placed under pressure until the adhesive is cured. Once the adhesive is fully cured, the panel can be trimmed and the desired final carvings can be routed or carved. For precise lines and fine details, a CNC machine would be the ideal tool for making perfect lines. With the inlay, or embedded material, matching the skin material, the finished panel will appear to be made of solid lumber, but will have the lightweight and increased strength of the hollow core material.

Blow molding process and apparatus

In at least some implementations, a blow molding apparatus provides that portions of the parison are engaged by one or more clamping devices disposed on or adjacent to the blow mold parts, and that the blow mold is opened whereby the parison is torn apart between the clamping devices, into two or more pieces of the parison. In other implementations, the clamping devices may be moved relative to the blow mold to tear the parison, or the parison may be torn by a combined movement of the blow mold parts and clamping devices.

Skin antiseptic applicator and methods of making and using the same
09999757 · 2018-06-19 · ·

The invention relates to applicators for applying a solution or other composition (e.g., an antiseptic composition) to skin of a patient. The applicator may include a container body having a proximal end, a distal end, and a frangible member disposed at the distal end of the body. The applicator includes a first position where the container body and frangible member are a unitary piece (e.g., blow molded as a single piece), and a second position when the frangible member is rotated relative to the body to irreversibly break a weak point therebetween, releasing the composition in the hollow body through an opening. A porous applicator head may be positioned adjacent the distal end of the body and frangible member, so that the composition flows out the body, through the opening, and onto the head. The applicator may be formed in a blow-fill-seal process for improved sterility and ease of manufacture.

FLOOR COVERING WITH UNIVERSAL BACKING AND METHODS OF MAKING AND RECYCLING

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer operatively connected to the stitches to provide dimensional stability for the entire floor covering. The reinforcement layer is made of fibers and adhesive that are formed into a reinforcement layer of laminated fibers that is operatively connected to the stitches and/or the fibers and adhesive are formed into a layer of fibers and adhesive that is contained within the stitches. The fibers and adhesive are mixed and then moved by an applicator toward the stitches. A curved slip path is formed on a curved portion of the applicator to improve the movement of the fibers and adhesive toward the stitches. A removable tip portion on the end of the curved portion of the applicator improves the penetration of the adhesive and provides compression of the fibers towards the ends of the stitches. A releasable adhesive cover system is provided to cover the layer of fibers for providing additional strength and stability and for providing a releasable attachment of the universal floor covering to a supporting surface.

Method and apparatus for forming leak detectable geomembrane liners

A method for forming a geomembrane liner testable for leaks by securing adjacent panels together with the conductivity of the lower surface of an overlying panel broken along a line adjacent the panel overlapping edge, and the overlapping edges sealed along the line. A heat welder has slots for the overlapping panel edges, with a heated wedge between the slots and having a projection to break the conductivity of the overlying panel bottom surface as it passes the wedge. The slots merge to press the liner edges together to heat weld them along the line of broken conductivity as the welder is moved along the panel edges.

GUIDE DEVICE AND SCARFED SURFACE FORMING METHOD
20180104918 · 2018-04-19 ·

Provided is a router guide that comprises: a guide part that has a first through-hole and a guide surface that guides a cutting tool attachment part of a router device along the first through-hole; a maintaining part that maintains the position of the guide surface; and a positioning part that positions the guide part. The guide surface is formed such that, in a state where the maintaining part is in contact with a surface of a composite material, the distance from the surface becomes smaller as the guide surface approaches a second through-hole. The guide part is formed so as to be elastically deformable. In a case where the guide part is caused to elastically deform along the surface shape of the composite material, the maintaining part maintains the position of the guide surface with respect to the surface at a position that corresponds to the surface shape.

MOLDING METHOD

A method of molding a composite structure having continuous fibers contained therein is disclosed. The method including the steps of compressing a first composite material in a mold; forming a cavity in the first composite material; placing a second composite material having continuous fibers contained therein in the cavity formed in the first composite material to minimize movement and distortion of the continuous fibers; compressing the first composite material such that the compression of the first composite material causes the first composite material to flow to edges of the second composite material; and allowing the first composite material to bond to the second composite material under molding temperature and pressure to form the composite structure.

COLLAPSIBLE VANE STRUCTURE AND RELATED METHOD FOR A SHADE FOR AN ARCHITECTURAL OPENING

A base structure and associated method for converting the base structure into an operable vane on a shade for an architectural opening. The base structure includes a back sheet and a front sheet attached together in engagement regions spaced along the length of the back sheet and front sheet. The front sheet is separated into front strip sections having a free end. Operating elements are positioned along the back sheet and situated so as to move relative thereto. The operating elements are attached adjacent to a free end of the front strip. Movement of the operating elements actuates the free end of the front strip to move from a closed position to an open position as desired by the user.
