A method is shown for installing a heat tube on a section of pre-insulated piping. A metal carrier pipe is covered with a first layer of foam insulation. Next, a wire brush is used to cut a longitudinal slot along the length of the pipe so that the pipe exterior surface is exposed from the insulation. A heat tube is then installed within the longitudinal slot, whereby the heat tube contacts the exterior surface of the metal carrier pipe. A second layer of foam insulation is then sprayed onto the exterior of the metal carrier pipe, covering the previously formed longitudinal slot and installed heat tube. A polyolefin coating is then applied over the insulation to form a protective outer jacket for the insulated pipe.

This invention provides methods for processing of platinum metallized high temperature co-fired ceramic (HTCC) components with minimum deleterious reaction between platinum and the glass constituents of the ceramic-glass body. The process comprises co-firing a multilayer laminate green ceramic-glass body with via structures filled with a platinum powder-based material in a reducing atmosphere with a specified level of oxygen partial pressure. The oxygen partial pressure should be maintained above a minimum threshold value for a given temperature level.

Methods and systems are provided for fabricating a composite structure. In one example, the composite structure may include a honeycomb core sandwiched between face sheets. An edge of the honeycomb core may be abraded and a top face sheet may be perforated. As such, a likelihood of delamination of the composite structure during a curing step may be reduced.

A method for processing a silicon wafer with a through cavity structure. The method is operated in accordance with the following sequence: performing ion implantation on a silicon wafer or pattern wafer; implanting a dummy substrate; bonding the silicon wafer to the pattern wafer; performing grinding and polishing, and thinning the pattern wafer to a depth exposing the pattern; bonding; and peeling the dummy substrate. Compared with the prior art, the present invention is standard in operation, and the product quality can be effectively guaranteed. The product has high cost performance and excellent comprehensive technical effect. The present invention has expectable relatively large economic values and social values.

An environmentally friendly composite material for use in the manufacture of professional grade skateboard decks and other high quality equipment and sporting gear. In the one embodiment, a skateboard deck is manufactured from a composition of recycled hard rock maple wood fibers, a polyvinyl acetate adhesive, a cross-link catalyst and water. The malleable nature of the composite material prior to curing, allows the skateboard deck to attain virtually any desired shape. Differing composites and adhesives may be employed to achieve the a similar product when properly cured. Once cured, the composite material is light weight, strong, durable, and requires no lacquers or other sealers.

A surfacing product (e.g., flooring element) can be elongate along a longitudinal axis. The surfacing product can have a core having a first surface and an opposed second surface that are spaced along a thickness axis. A veneer can be coupled to the first surface of the core. The veneer can have a first veneer segment that is elongate along the longitudinal axis, a second veneer segment that is elongate along the longitudinal axis, and an insert segment positioned between the first veneer segment and the second veneer segment along the longitudinal axis.

A repair apparatus for an electrically conductive layer of a composite structure includes a dielectric layer, having a perimeter, secured to the composite structure, a first adhesive layer, and a conductive layer, secured over the dielectric layer and to the composite structure via the first adhesive layer around an entirety of the perimeter of the dielectric layer, the first adhesive layer being scored along a perimeter region thereof to improve a conductive path between the conductive layer and the composite structure.

A jewelry ring that includes a sleeve-like or annular substrate made of a precious metal or a precious metal alloy having a specific density 1, and which has an inner surface for contacting a finger, an outer surface, two lateral surfaces and a central cavity for accommodating the finger. A bundle of fibers is wound in multiple windings on at least a part of the outer surface. The fibers are connected to one another by a plastic adhesive having a specific density of 2<1. The fibers have a specific density 3<1. Also a method for manufacturing a jewelry ring, which includes wetting the bundle of fibers with plastic adhesive, fastening a start of the bundle to the sleeve-like or annular substrate, winding the bundle on the sleeve-like or annular substrate, applying pressure to the bundle, curing the plastic adhesive and grinding off peripheral-most fibers.

A method is shown for installing a heat tube on a section of pre-insulated piping. A metal carrier pipe is covered with a first layer of foam insulation. Next, a routing device is used to cut a longitudinal slot along the length of the pipe so that the pipe exterior surface is exposed from the insulation. A heat tube is then installed within the longitudinal slot, whereby the heat tube contacts the exterior surface of the metal carrier pipe. A second layer of foam insulation is then sprayed onto the exterior of the metal carrier pipe, covering the previously formed longitudinal slot and installed heat tube. A polyolefin coating is then applied over the insulation to form a protective outer jacket for the insulated pipe.
