Methods and apparatus to form venting channels on a panel for a decorative layer are disclosed. An example method includes contacting an outer surface of a tool to an outer resin layer of a panel. The outer surface of the tool has protrusions. The example method includes moving the outer surface of the tool on the outer resin layer of the panel in a first direction to cause the protrusions of the tool to form first venting channels on the outer resin layer of the panel and coupling a decorative layer to the outer resin layer of the panel via an adhesive layer. The first venting channels are to vent at least one of gas or vapor away from the decorative layer to deter separation of a portion of the decorative layer from the outer resin layer.

The application relates to a method for producing a double-walled pipe (1) and a pipe (1) of this type, having an outer pipe (3) which is press-fitted with an inner pipe (2) consisting of a corrosion-resistant alloy, wherein an adhesive (4) is inserted at least in regions between the outer pipe (3) and the inner pipe (2), wherein, after adhering the inner pipe (2) with the outer pipe (3), the inner pipe (2) and the adhesive layer (4) are removed at the pipe ends, and the inner side of the outer pipe (3) is plated via an integral connection with the inner pipe (2).

The present application provides a screen protector and a method for applying a screen protector, including a release film, a hydrogel film, a silicone protective film, and a release liner sequentially stacked, an edge of the release film is provided with positioning lug, the silicone protective film is provided with a die-cutting line, an edge of the first part protrudes outwards to form a first lug, and an edge of the second part protrudes outwards to form a second lug. The silicone protective film is divided into two parts, tearing off the first part and tearing off the second part are independent from each other, avoiding the movement of the screen protector due to the large amplitude of the tearing film during the tearing process, the deviation occurring during the applying process of the screen protector is avoided, and the applying efficiency of the screen protector is improved.

Mining methods and systems are disclosed for In-Situ Leaching (ISL) of the mineral ores. ISL extraction is conducted by injecting a suitable leach solution into the ore zone below the water table; oxidizing, complexing and mobilizing the minerals; recovering the pregnant (loaded) solutions through production wells (extraction wells or recovery wells); and, finally, pumping the minerals bearing solution to the surface for further processing. In these methods strips of fabrics saturated with resin are helically or non-helically wrapped around desired shape vertical mandrels, located over the wells, and the partially cured pipes are lowered into the wells to line the wells. These onsite manufactured pipes/linings are used to pump chemical solutions into the ores and subsequently to recover the pregnant (loaded) solutions.

A structure including an electro-active-polymer (EAP). The structure can take the form of a strap, which includes two or more EAP film layers. The structure can further include one or more holders or end-grabbing portions. Methods of making and using the EAP structure are also envisioned.

A method for producing a liner hose (2) for lining pipelines, comprising the method steps of moving a circumferentially closed inner film hose (4) over a winding mandrel (6) of a winding apparatus (8) and wrapping the inner film hose (4), which is guided on the winding mandrel (6) by means of a guide mechanism (18), with a fibrous strip (12) which has been impregnated with curable reaction resin, is characterized in that the inner film hose (4) is guided via endless pulling means (14) that circulate without a drive, and in that the inner film hose (4) that has been wrapped with the fibrous strip (12) is moved off of the winding mandrel (6) solely by a pull-off mechanism (16) which acts from the outside on the fibrous strip (12). The invention further relates to a device for carrying out the method.
