Abstract: The present invention relates to the field of laboratory-scale sample preparation, which describes a methodology for the specific isolation of tetraprotic naphthenic acids, called ARN acids, from residual naphthenate deposits from petroleum production. The method consists of cleaning the naphthenate deposit, converting the naphthenate salts to naphthenic acids and isolating the ARN acids from the other organic acids, using a silica-based sorbent material with aminopropyl functional groups, previously selected for an efficient elution of different functional groups and polarities.

Abstract: The present invention is based on the application of heating resistors by a temperature regulation circuit in certain points of the catalyzer so that this comes into operation in the least time possible, reducing most of the amount of low molecular stability or environmentally harmful substances. Likewise, little tumult are added to each monolith duct to raise exhaust gas turbulence and increase the contact between the reduction and oxidation agent, whether it be platinum, palladium and rhodium.

Abstract: An electrical appliance includes a rotating food processing screw for processing food items exiting the outlet of a chute. The screw is coupled to an electric drive motor for driving the screw in rotation about itself around its central axis. An upper part of the screw has a sweeper for sweeping the outlet of the chute, and a lower part drives down towards the bottom and presses the food fragments coming from the upper part of the screw. Food blocking elements can block the food items. An inscribed sphere, which is geometrically defined by the chute, is movable within the interior of an upper part of a chamber receiving the screw. Two zones of contact between the inscribed sphere and the blocking elements are formed, and a third zone of contact is between the inscribed sphere and the sweeper.

Therefore, a portion of the primary conveyor is sandwiched in between the lower high-angle conveyor and the upper high-angle conveyor. Both of the lower high-angle conveyor and the upper high-angle conveyor are disposed at a high angle. Material is transported along the primary conveyor and then transported at a high angle in between the lower high-angle conveyor, the primary conveyor, and the upper high-angle conveyor.

Abstract: The invention relates to containers commonly used for the sale of wine, including a tap essentially comprising a stationary body and a deformable elastic plug that tends to stay closed. According to the invention, transverse grooves are provided at one of the rear corners of each of the windows in which the flanges move and, by means of the angular rotation of the cylindrical cap, said grooves can be used to lock the flanges axially in the forced closed position, before and after removing the seal, thereby hindering the opening of the tap, which requires a combined rotation and pulling movement. In addition, the stationary and moving elements include coaxial through-holes allowing the installation of a padlock preventing unauthorized persons from accessing the container.
