Abstract: Improvements in an outside house vent that blocks embers, water and rain that can cause damage to a house of building. The prevention of fire and ember intrusion into a building prevents fires in homes where invalids and children are left alone. The prevention of water into structure further reduces the potential for mold growth in the attic or walls of a home or structure. The filtering further prevents intrusion of creatures such as but not limited to bugs, insects, bees, wasps, animals, critters and other flying and crawling animals from entering the building. The vent is a fireproof set of louver or filter pads with fire arresting screens that is passed through a wall that vents into the building. The vent can be installed on old and new construction to provide improved fire prevention, increase the value and salability in fire prone areas.

Abstract: An autonomously operated automated food dispenser provides sustenance to one or more animals at prescribed intervals. The dispenser is portable and suitable for use for animals in space vehicle life support systems. A micro-controller controls operation of the outlet valve of a food reservoir that contains a food paste maintained under pressure by a pressurized gas source. Predetermined volume of food paste are extruded through the outlet upon the micro-controller's command. The food cannister is characterized by a novel two part assembly and houses a rolling diaphragm. Pressurized gas is applied to the bottom of the diaphragm, allowing the diaphragm to roll against the food paste, when the outlet valve is opened.
