Abstract: A bow-type throwing tool includes a central body, a nocking string for an arrow, and elastic energy storage mechanism operated by the traction of the string. The elastic energy storage mechanism includes: two opposed primary levers connected with hinging to the central body, the nocking string being constrained by its opposite ends to opposite free ends of the primary levers; two opposed axial action thrust accumulators, defined on the central body; a loading element of the axial action thrust accumulators configured to induce a compression in the thrust accumulators following a traction of the nocking string.

Abstract: A thermal insulating unit includes a sealed inner gas-permeable bag containing an insulating micropowdered material, such inner bag having two major surfaces parallel to each other. Two multilayer sheets are respectively disposed on opposite sides of the gas-permeable bag and overlap the same, each sheet being formed of an innermost layer and an outermost layer of a thermoweldable plastic and an intermediate metal layer. The metal layer has smaller dimensions than the plastic layers such that each metal layer wholly covers only its corresponding inner-bag major surface. The four plastic layers are peripherally heat-sealed, the resulting outer bag having been evacuated. A device is provided on each metal layer for fixing such layer to and positioning it with respect to its respective two plastic layers.

Abstract: A refrigerator door comprises an inner panel and an outer panel forming the wall of the door and has a drink container removably associated with the inner panel. A drink-delivery tube communicates with the interior of the container and is hingedly movable against a resilient bias from an inoperative position to a delivery position, the tube extending through the wall of the door and terminating in a spout. A slide is associated with the tube for effecting such movement thereof and is movable from the outside of the door in a vertical opening formed in the outer panel of the door wall. A compartment accessible from the outside of the door without opening the same is provided in the door, the compartment being divided into a lower compartment for placement of a cup and an upper compartment for reception of the tube spout. A pivotal partition controllable by the slide separates the lower compartment from the upper compartment.
