Abstract: A folding device (14?, 14?) includes a driven contact device (15?, 15?) configured for continuously creating a fold in a moving article (12) during an operative folding mode of the folding device. In the operative folding mode, the article moves along a base plane in a motion direction (MD). The folding device includes a support structure (54) connected to, and configured for supporting, the contact device. The contact device includes a peripheral surface (48) which extends at least partially about at least one rotation axis. The peripheral surface includes multiple fingers (44) which protrude outwardly away therefrom. In the operative folding mode, the fingers consecutively and incrementally engage and fold the article starting at an edge (28) defining an outline thereof.

Abstract: A device for sorting insects into two or more classes based on size, the device comprising a drum with openings along the circumference. The insects are introduced to the drum at a first end, and the openings are sized to allow a first class of the insects to exit the drum through the circumference and the openings while the second class is retained to travel to far end of the drum, thereby sorting the insects into the classes. The drum may be held at a tilt to enable flow within the drum. The drum may rotate and a built in helix or helical screw may assist with flow. Water may be poured from above or from inside to flush insects through the openings or flush stuck insects back into the interior.

Abstract: A method of applying an operation to an individually separated and immobile insect comprises directing a mass of insects onto a permeable surface, and applying a pressure gradient through the permeable surface to apply suction of the insects down into the surface, to immobilize the insects. The operation, whether it be counting, classification, sorting or sterilization, is then carried out on the immobilized insects.

Abstract: An inflatable cellular cushioning material having an air inlet pipe path to be inflated by an inflating device through the use of an air inlet pipe, the inflatable cushioning material comprising at least two layers of plastic pre-welded in such a manner so as to form a substantially diagonally oriented lines forming sleeves along the longitudinal axis of the inflatable cellular cushioning material and a substantially horizontal welded lines along the path of the air inlet pipe whereby the horizontal welded lines substantially reduce the non-inflated areas along the path of the air inlet pipe.

Abstract: A system and method are disclosed for the provision of assisted breathing by the delivery of a controlled pressurized airflow to the pulmonary airway of a user with breathing disorders. The system comprises a source of compressed respiratory gas (112), a user interface unit (115) including at least one Venturi device (120) and a thin flexible tubing (116) connecting between the source of high pressure gas (112) and the Venturi device. The system and method provide a regulated and controlled flow of air to the user (105) in accordance with the user needs. The invention further discloses a novel small light-weight user interface for replacing prior art breathing masks.

Abstract: An inflatable cellular cushioning material (300) having an pipe entry line (314) to be inflated by an inflating device through the use of an air inlet pipe, the inflatable cushioning material comprising at least two layers of plastic welded in such a manner so as to form a substantially horizontally oriented longitudinal lines forming at least one row of cells (320) having at least one opening (336) forming a brick like formation along the horizontal axis of the inflatable cellular cushioning material, such that a flow of air is possible from one cell to another along the horizontal span of the inflatable cellular cushioning material.
