A mineral-based floor panel including a mineral-based core, wherein the panel includes at least one groove. The at least one groove may be provided in a rear side of the panel. There is also disclosed other such mineral-based panels, such as a building panel, a wall panel, a ceiling panel or a furniture panel. There is also disclosed a method for forming such grooves in a mineral-based panel. Furthermore, there is disclosed a mineral-based panel including a mineral-based core and polymer-based lower layer(s) attached to the core. A locking system of the panel includes a strip extending horizontally beyond an upper portion of the panel, wherein at least a horizontal portion of the strip is entirely formed in the polymer-based lower layer(s).

Mineral-based panel comprising grooves and a method for forming grooves

A mineral-based panel including a mineral-based core and at least one groove. The at least one groove may be provided in a rear side of the panel. The mineral-based panels may be floor panel, a building panel, a wall panel, a ceiling panel or a furniture panel. A method for forming such grooves in a mineral-based panel. Furthermore, a mineral-based panel including a mineral-based core and polymer-based lower layer(s) attached to the core.

A method of making a controlled swell-rate swellable packer comprises disposing a sealing element about at least a portion of the mandrel, applying a mask onto at least a portion an outer surface of the sealing element, wherein the sealing element comprises a swellable material, and wherein the mask comprises void spaces, and applying a jacket to the sealing element not covered by the mask. The jacket may be disposed such that it covers at least a portion of an outer surface of the sealing element. The jacket is configured to substantially prevent fluid communication between a fluid disposed outside of the jacket and the portion of the outer surface of the sealing element covered by the jacket. The mask may be removed from the sealing element after applying the jacket to the sealing element not covered by the mask.

Method for making controlled swell-rate swellable packer

A controlled swell-rate swellable packer comprises a mandrel; a sealing element, and a jacket. The sealing element is disposed about at least a portion of the mandrel, and the jacket covers at least a portion of an outer surface of the sealing element.
