An adaptive sheet that includes a first layer defining a first length, the first layer configured to assume a base configuration in response to a first environmental condition and assume a lofted configuration in response to a second environmental condition with the first layer being curled along the first length compared the base configuration. The first fabric layer includes a first material defining a second length and having a first expansion coefficient, and wherein the first material is configured to increasingly change length along the second length in response to the second environmental condition, and a second material defining a third length and having a second expansion coefficient that is different than the first expansion coefficient.

The present invention is directed to a weather-proofing solution for protecting a cable that includes a new weather proofing sheet, a new applicator tool and a new method of installing the weather proofing material over a cable connection to provide environmental protection to the cable connection. The weather-proofing material is a preformed sheet having a body portion and two spaced apart tail portions extending longitudinally from one end of the body portion wherein the preformed sheet has a variable elongation along its length when wrapped around the cable connection under a constant force.

Disclosed is a spectrally selective solar absorbing coating and a method for making same. The spectrally selective solar absorbing coating includes a multilayer stack including, from the substrate to the air interface: substrate (1), infrared reflective layer (2), barrier layer (3), composite absorbing layer (4) consisting of metal absorbing sublayer (4.1), metal nitride absorbing sublayer (4.2), and metal oxynitride absorbing sublayer (4.3), and antireflective layer (5). Therefore, the solar absorbing coating has good high and low temperature cycle stability and superior spectrum selectivity, with a steep transition zone between solar absorption and infrared reflection zones. It has a relatively high absorptance α>95%, and a low thermal emissivity ε≤4%, PC (performance criterion)=-0.3. The solar absorbing multilayer stack can be obtained by reactively magnetron sputtering the metal target in argon or other inert gas with some amounts of gas containing oxygen or nitrogen or their combination.

The present invention relates to improvements in reclosable packages (10) suitable for a comestible product, such as a chocolate bar, and in particular to reclosable packages which allow a consumer to separate portions of the product and the package, and to reclose the package after removal of the portion(s). The package has at least one side wall defining an interior of the package for receiving a product. The package is formed from a multi-ply material comprising at least an inner layer (11) peelably adhered to an outer layer (12). A plurality of lines of weakness are provided in the outer layer (25) spaced apart along a first direction of the package and a corresponding plurality of longitudinally spaced apart lines of weakness (26) are provided in the inner layer. Each line of weakness extends in a second direction which is generally transverse to the first direction. The lines of weakness in the inner layer are offset in the first direction to the corresponding lines of weakness in the outer layer, such that the side wall is separable along a corresponding pair of lines of weakness in the inner and outer layer to form two package sections, each package section having an inner layer flap (36, 37) and an outer layer flap (35, 38) formed by the separation of the inner and outer layers providing means for reclosing the package sections.
