Abstract: The disclosed technology includes a fluid heating device including a frustoconical combustion chamber and a heat exchanger that can include heating tubes. The combustion chamber can have a first end and a second end that is in fluid communication with the heating tubes. The surface area of the second end of the combustion chamber can be larger than the surface area of the first end of the combustion chamber.

Abstract: A fastening device for fluid tightly coupling a first duct body and a second duct body of a heat exchanger is provided. The fastening device includes a support member to couple with a connecting edge of the first duct body. The support member includes a pivot pin and a locking device disposed at an offset distance from the pivot pin along a radial axis of the fastening device. The fastening device further includes a pivot arm having a first end to engage with the pivot pin and a second end to engage with a flange of the second duct body. The locking device engages with the pivot arm and move the second end of the pivot arm relative to the pivot pin to fluid tightly engage the flange of the second duct body with the connecting edge of the first duct body.

Abstract: A method and system for producing panela cheese resulting as by-product whey without salt or with minimal amount of salt, the method includes processing milk to produce a mixture of cheese curds and whey, wherein optionally the mixture is salted by incorporating a fraction of a total amount of salt required for the manufacture of the panela cheese concerned; extruding, forming and pressing the cheese curds to form cheese blocks and/or simultaneously draining the whey from the cheese curds; optionally subjecting the obtained cheese blocks to a cooling process or a fast cooling process; and promoting absorption of salt by injecting brine to the cheese blocks, wherein the amount of salt absorbed by the cheese block from the brine represents the complement of the total amount of salt required for the manufacture of the panela cheese concerned. The system includes a vat, a cheeseformer apparatus, and a brine injector.

Abstract: A method for testing the hermetic sealing of packages, comprising subjecting the package to two or more moderate depressurization cycles in order to cause stress to the package followed by a final depressurization step at a high negative pressure in order to reveal possible failures and air leaks.

Abstract: A package which is sealed with at least one baffled venting closure system, said baffled venting closure system being formed of at least two closure-lines which extend across the width of the package, and an air flow passage formed between the at least two closure-lines, wherein each of said closure-lines form one or more closure-line vents which allow air to vent out of the interior of the package into the air flow passage and out of the bag to the environment external to the package, and wherein at least one of said closure-lines has at least one wall segment parapeting said closure-line from the closure-line vent adjacent thereto.

Abstract: A semi-enclosed applicator, such as a mitt, for distributing a substance onto a target surface. The mitt has a first layer, a second layer in face-to-face contact with the first layer, and a third layer in face to face contact with the second layer. The first and second layers are positioned to form a cavity to allow for a product dispensing reservoir to be placed. The first layer, second layer and reservoir are removably attached to the third layer for removal by the user after use.
