A multilayer insulation is provided that includes radiant barrier layers separated by one or more spacers. The spacers are configured to maintain separation and provide a low conductivity thermal path between adjacent radiant barrier layers of the multilayer insulation. In certain implementations, the spacers have a shape defined by the intersection of three orthogonally oriented discs and are disposed between two radiant barrier layers of the multilayer insulation. In other implementations, the spacers are mechanically coupled to and extend from a radiant barrier layer.

A heat insulating material includes a porous sintered body formed of MgAl.sub.2O.sub.4 and having a porosity of 60% or more and less than 73%. In the heat insulating material, pores having a pore diameter of 0.8 m or more and less than 10 m occupy 30 vol % or more and less than 90 vol % of a total pore volume, pores having a pore diameter of 0.01 m or more and less than 0.8 m occupy 10 vol % or more and less than 60 vol % of the total pore volume, the thermal conductivity at 20 C. or higher and 1500 C. or lower is 0.45 W/(m.Math.K) or less, and the compressive strength is 2 MPa or more.

The present invention belongs to the field of thermal functional devices. Provided is a topological insulation device having negative thermal expansion. In the topological insulation device, three assemblies of different properties are constructed using assembly units of special geometric structures, and then different assemblies are assembled to form an outer heat-conduction ring and a thermal insulation region, which is wrapped by the outer heat-conduction ring, so that the device has the characteristics of surface thermal conduction and internal thermal insulation, and an edge state and a topological protection property, which are similar to those of an electrical topological insulator, are realized in a macroscopic heat conduction process.

A bayonet coupling system includes a bayonet, a bayonet coupler, and a seal. The bayonet includes a bayonet tube configured to enable the flow of hydrogen fuel therethrough, and a flange coupled to the bayonet tube. The seal is configured to surround the bayonet tube and contact the flange along one side of the flange. The bayonet coupler includes a bayonet coupler tube having an inside diameter larger than an outside diameter of the bayonet tube, the bayonet coupler tube configured to receive the bayonet tube and to seal against the flange at the seal. The bayonet coupler is fixedly mounted directly or indirectly to a hydrogen storage tank such that a longitudinal axis of the bayonet coupler is inclined a predetermined angle with respect to horizontal to prevent a substantial thermal gradient from forming at the seal.

Provided herein are products, methods, and kits, for use in regulating the temperature of an object. The present invention relates to thermal insulating liners for regulating the temperature of perishable goods or temperature sensitive products. The thermal insulating liners generally may be dimensioned to fit within a container. The thermal insulating liners may be quickly collapsed and reconstructed to improve stackability and diminish the amount of space required to store the thermal insulating liners prior to use.

The invention comprises a product. The product comprises a foam insulating panel, the panel having a first primary surface and an opposite second primary surface, wherein the foam insulating panel defines at least one recessed channel in the first primary surface, the at least one recessed channel being sized and shaped to provide a mold for a structural reinforcing member. The product also comprises a concrete panel formed on the first primary surface and filling the at least one recessed channel so as to provide a structural reinforcing member for the concrete panel. The product further comprises an elongate anchor member in the foam insulating panel and extending from the first primary surface of the foam insulating panel into the concrete panel. A method of making a composite reinforced insulated concrete structure is also disclosed.

The manufacture of a thermal insulating product whereby a foam is produced from a mixture of mineral particles, the product is shaped, and the foam is dried. Specifically, the foam is produced from a crystallized calcic part and a crystallized magnesian part, and a composite aggregate of the crystals of the calcic and magnesian part is formed. The calcic part is chosen from calcite and/or aragonite, and the magnesian part is made of hydromagnesite.

Presently disclosed self-regulating thermal insulation may include one or more thermal actuators that may expand and contract in response to changes in temperature adjacent the thermal insulation, thereby automatically changing the thermal resistance of the thermal insulation. In this manner, a self-regulating thermal insulation may be configured to locally adjust in response to local changes in temperature of a part being insulated, for example, during curing or some other manufacturing process. Such self-regulating thermal insulation may be configured to respond to temperature changes without feedback control systems, power, or human intervention. One example of self-regulating thermal insulation may include a first plate, a second plate, a support structure coupling the first plate and the second plate and defining an insulation thickness therebetween, an internal partition positioned between the first plate and the second plate, and at least one thermal actuator positioned between the second plate and the internal partition.
