A non-ceramic, light-weight outdoor cooker made from formed sheet metal includes a double-walled kettle, with an inner wall spaced and insulated from an outer wall by an insulating layer. A domed lid is constructed similarly to the double-walled kettle and is hinged to the top of the kettle. By spacing the inner wall from the outer wall and providing an insulating layer, heat transfer to the outside of the cooker is greatly slowed. By constructing the structure of sheet metal, instead of ceramic, the cooker is light-weight, rugged, and economical to manufacture.

A method of forming a thermally insulating body that may involve co-depositing onto a substrate, particles containing aerogel material, particles containing phase change material, and a solution containing a binder and a carrier. The phase change material may have encapsulated phase change material particles in which a phase change substance encapsulated within durable capsules transitions from a solid to a liquid at a temperature greater than about 100 degrees Fahrenheit. The carrier may be removed after the co-deposition to form a solid thermally insulating body on the substrate.

A thermal control unit with a heat pipe that conducts heat away from a device under test during burn-in. The heat pipe has a heater that allows control of the rate at which heat is transferred from the DUT to the heat pipe. A sensor and controller are provided to control the heat in response to the measured temperature of the DUT. The sensor and controller control the heater to maintain the surface temperature of the DUT within a specified range.

The invention discloses an energy storage power station battery thermal runaway protection system which comprises solid-solid composite phase change material heat dissipation plates tightly attached to the two sides of battery modules. The battery modules are formed by connecting a plurality of single batteries in series, and the batteries are attached to the solid-solid composite phase change material heat dissipation plates through heat conduction and insulating double-faced adhesive tapes. Cold liquid plates are arranged between the adjacent battery module bodies, and the cold liquid platesare arranged between the battery modules in an S shape. Heat conduction silica gel layers are arranged between the solid-solid composite phase change material heat dissipation plates and the cold liquid plates, and the solid-solid composite phase change material heat dissipation plates are made of a paraffin / expanded graphite solid-solid composite phase change material. Al2O3 / H2O nano sol coolingliquid is adopted as cooling liquid in the cold liquid plates. Through combination of the solid-solid phase change material and the liquid cooling plates, efficient heat dissipation of a faulted thermal runaway battery is realized, and chain fire accidents caused by thermal runaway propagation of the battery are avoided.

The invention relates to a 162-degree LNG stop valve. The technology of a shrinkable elastic valve rod provided with a prestress spring, the maze sealing technology, the multi-sealing all-welded valve technology and the like are adopted, the LNG stop valve can freely shrink according to the temperature difference stress of a low-temperature valve body so as to adapt to changes of temperature of the valve body, stress required by the sealing face of the valve can be maintained, and leakage caused by temperature difference strain can be prevented. The height of the whole valve rod can be effectively reduced, the whole size of the LNG stop valve can be reduced, and the dual functions of LNG stopping and safety are achieved; the design pressure of the valve and the design pressure of an LNG conveying system can be effectively reduced, the size of the valve can be smaller, the safety is higher, and the machining and manufacturing cost is lower.

A crystal-bead-contained glass has a circumferential wall in which a hermetical hollow chamber is formed. The glass forms a filling opening in communication with the hollow chamber for receiving crystal beads and water that are mixed according to a given ratio into the hollow chamber. The crystal beads, after mixed with water, expand and fill up the hollow chamber to form a sparkling visual effect. The crystal beads are mixed with water in a ratio of 7 gram of crystal beads added with 240 cc water, which provides the best resiliency and toughness. The crystal beads can be made with various colors to provide a colorful vision after mixed with water to attract the attention of consumers. The glass can be deposited in a freezer chamber to freeze the crystal beads so as to extend the time period of cold-keeping in using the glass to enjoy beverages.

A comfortably, yet highly efficient therapy pad that is effective in delivering cold or hot thermal therapy for the relief of pain, inflammation, swelling, and muscle stiffness.

The invention relates to a material for making a boot sole, and concretely relates to a puncture resistant boot sole material. The puncture resistant boot sole material comprises, by weight, 20-60 parts of natural rubber, 40-20 parts of chloroprene rubber, 40-20 parts of styrene butadiene rubber, 1.2-2.0 parts of sulfur, 0.3-0.8 parts of an accelerant DM, 0.3-1.0 part of an accelerant M, 5.0-7.0 parts of zinc oxide, 1.0-2.5 parts of stearic acid, 25-35 parts of high-wear-resistance carbon black, 0.8-1.5 parts of an antioxidant D, 1.0-2.0 parts of an antioxidant 4010 and 1.5-2.5 parts of magnesium oxide. The puncture resistant boot sole material has a reasonable design, and is designed through a ternary combination method of the chloroprene rubber, the natural rubber and the styrene butadiene rubber, so the molecular chain slip and fracture phenomena of the sole material are difficult when a sole meets a sharp object, thereby the puncture resistance of the boot sole is substantially improved.

The invention relates to a -162 DEG C LNG brake valve. According to the characteristic that the LNG brake valve needs two-way sealing and two-way brake, four one-way connecting pressure adjusting valves are arranged along the axis of a wedge disc, control pressure of the pressure adjusting valves can be set and adjusted respectively according to the specific requirement for the LNG pipeline process, LNG in a dead zone can be automatically guided out in a two-way mode, pressure of the two sides of the valves can be effectively controlled to be balanced, counter flow control is facilitated, and the safety functions of two-way brake, two-way sealing and two-way connecting of LNG are achieved. Meanwhile, by the adoption of the technology of retractable elastic valve rods provided with prestress springs, the labyrinth sealing technology, the multi-sealing all-welded valve technology and the like, design pressure of the valve and design pressure of an LNG conveying system can be effectively reduced, the size of the valve is smaller, safety is higher, and machining and manufacturing cost is lower.
