Abstract: A process for remediating salt-impacted soils includes forming a heap of salt-impacted soil on an impermeable surface; irrigating the salt-impacted soil heap with at least one amendment solution; and collecting a leachate containing sodium ions at a base of the heap. A system remediates salt-impacted soil.

Abstract: The present disclosure is a semi-automatic jar opener made up of a lower part including a run button activating an electric motor mounted under the lower part, which allows a lower plate to turn and activate a gear rack allowing the lower jaws provided with non-skid rubber strips to squeeze a jar according to the desired size, when the jar turns the friction rubber strips prevent it from sliding, and when the jar is unscrewed the electric motor stops automatically.

Abstract: The present invention is a semi-automatic device including an electric motor which is activated by a run button for making turn a lower plate on which is mounted two L-shaped bars containing teeth on a face for meshing with a small gear activating each jaw for squeezing a jar that is placed between each rubber strip mounted on the lower plate for it preventing to slide when it makes turn an upper plate under which is mounted two L-shaped bars containing teeth on a face for meshing with a small gear activating each jaw for squeezing a lid that is placed between each rubber strip mounted under the upper plate for it preventing to slide until the time that the lid become loose, and the electric motor stops automatically when the torque falls to zero.

Abstract: A die casting die particularly adapted for casting of parts with protruding heat sink pins. The die ejector half insert is made of two distinct pieces. One piece, the ejector cavity insert, includes through holes which define the heat sink pin-forming cavities. These cavities are closed by a combination of the second piece of the ejector half insert, and the ejector pins. The result is a more uniform part with less flashing, which ejects easily from the die. There is also less die wear associated with the ejector pins.

Abstract: The present invention relates to a scaffold for working under the stern of vessels for servicing propellers, propeller shafts, stern tubes, rudders and the like. The scaffold comprises a movable carriage to which is mounted a vertical support including actuating elements for raising or lowering a longitudinal platform at the upper part of the support. A further actuating element is used for longitudinally displacing the platform so as to reach the vessel parts to be serviced.
