Abstract: The present invention refers to a tubular escape system for buildings consisting of a combination of a platform, multiple uprights located around the perimeter of the platform to support the railings, a door connecting the building interior on that floor with each platform, a opening in each platform measuring 1.00 meter in diameter, two tubes that perpendicularly cross each platform and are connected to a water tank that can manually or automatically fill the tubes with water, an extension tube that remains fixed and inserted within the tube while the escape is not in use, a bolt that passes through the extension tube and so fixes it inside the extension tube, a sponge base to be found on each platform at the bottom of the section of tube on that platform, a cover attached to the base of the extension tube, an auxiliary ladder attached to the platform railings, an extension inside the tube that prevents anybody from entering by means of the opening on the lower platform.

Abstract: The present invention refers to improvements to receptacles for making ice cubes which make it possible to dislodge the ice cubes from the tray in an easy and simple manner once they have been taken from the freezer. Such is accomplished by means of a water chamber between the multiple mold and the tray which holds it, which upon being filled distributes water all around the ice cubes, dislodging them immediately. The tray also serves as a container once the cubes have been dislodged. To dislodge cubes it is unnecessary to hit the mold, submerge it in water or twist it.
