A system that provides for simultaneous thermal regulation of both components of a two-component system, while maintaining their separation prior to introduction into a conventional static mixer element, in order to assure that the mixed fluid, when dispensed, is at the optimal temperature and viscosity. The thermal capacity can be adjusted by altering the configuration to increase or decrease the thermal transfer area as required for each specific application.

Methods to prepare elastomer compounds are described that include dry mixing at least one additive to an elastomer composite masterbatch at low temperatures over a shortened mixing cycle with reduced energy consumption. The elastomer composite masterbatch is produced in a liquid masterbatch process. The resulting elastomer compounds are further described as well as property improvements that can be achieved.

An apparatus and system for managing the level of dissolved gases in water for aquatic life that provides sufficient water with sufficient oxygen saturation, without introducing excessive amounts of bubbles, and that can adequately degas or strip harmful dissolve gases from the water. The apparatus can generally comprise a storage compartment, a filter compartment, and a pump compartment. The filter compartment can be coupled with the storage compartment and comprise a filter element. The pump compartment can be coupled with the storage compartment and comprise a venturi air intake port, a degassing vent, a pump filter element, and a pump assembly. The pump assembly can comprise a venturi nozzle coupled with the venturi air intake port and a flow pump in fluid communication with a flow pump intake port. The pump filter element can at least partially encircle the flow pump intake port.

A method for producing a thermal product with a consistent and designable thermal property is disclosed. The method comprises producing from a municipal waste a cellulose-based material stockpile and a plastic-based material stockpile; automatically measuring at least one physical property of the cellulose-based material stockpile and at least one physical property of the plastic-based material stockpile; based on the measurements of the at least one physical property the cellulose-based material stockpile and the measurements of the at least one physical property of the plastic-based material stockpile, automatically controlling mixing the cellulose-based material stockpile and the plastic-based material stockpile to form a mixture by adjusting a ratio of the cellulose-based material stockpile to the plastic-based material stockpile; and automatically heating and compressing the mixture to form the thermal product.

Disclosed is an apparatus and a method for converting a sheet into a continuous strip, wherein the sheet has a sequence of cuts extending in a cutting direction transversely across the sheet with respect to the longitudinal direction to form a plurality of interconnected sheet sections, wherein the continuous strip has zig-zag sections, wherein the sheet sections are arranged to be pulled apart in a feeding direction to form the zig-zag sections, wherein the apparatus includes a separator device with a retaining device for retaining an upstream sheet section with respect to a consecutive downstream sheet section in the feeding direction and a sensor device for detecting the pulling apart of the downstream sheet section from the upstream sheet section.

Disclosed is a system for production of a cosmetic product including: at least one first single-use packaging unit including a preset quantity of a first phase of a cosmetic product, at least one second single-use packaging unit including a preset quantity of a second phase of a cosmetic product, a machine including a mixer inside of which the mixture of the preset quantity of the first phase and the preset quantity of the second phase is done automatically in order to end up with a cosmetic product directly consumable by the end consumer. The mixing is done in a manner such that neither the first phase nor the second phase are in direct contact with any part of the mixer which is not single use, thus avoiding dirtying the mixer.

A device for mixing powders by cryogenic fluid, characterised in that it comprises at least: a chamber for mixing powders, comprising a cryogenic fluid; a chamber for supplying powders in order to allow the powders to be introduced into the mixing chamber; means for agitation in the mixing chamber so as to allow the mixing of the powders placed in suspension in the cryogenic fluid.
