Abstract: Control of air cushion vehicles is obtained by controlling the translation of the vehicle independently from control of the rotation (yaw). Lateral translation of the vehicle is controlled by creating side-directed thrusts the direction of which passes through or as close as possible to the yaw axis by diverting variably controllable flows of air from the flow of air used to create a propulsive air thrust for forward translation of the vehicle to left and right lateral control ports located more or less parallel to the fore-aft axis of the vehicle sufficiently proximate to a plane which passes through the yaw axis and is perpendicular to the fore-aft axis of the vehicle so that diverted air flows exiting the ports approximately perpendicular to the fore-aft axis create thrusts which predominantly pass through the yaw axis. (In the absence of external forces the yaw axis passes through the center of gravity of the vehicle.

Abstract: A modular chassis for a front engine-rear drive motor vehicle is described which comprises as structural components a front structural member comprising the engine and attachment points for front suspension members is attached rigidly and detachably to a middle structural member comprising a tube and the middle structural member is attached rigidly and detachably to a rear structural member comprising a transmission and attachment points for rear suspension members wherein the middle structural member is longitudinally disposed on the center line of the vehicle between the front structural member and the rear structural member and supports the majority of the torsional, lateral and longitudinal loads created between the front and rear structural members and the front and rear structural members support the torsional, lateral and longitudinal loads created between each and the middle structural member.

Abstract: An exhaust fixture adapted to be connected to a toilet, the toilet having a bowl, a water tank having a normal amount of water therein and an upper, peripheral edge, an overflow pipe located within the tank, and a lid adapted to fit about the peripheral edge of the tank; the exhaust fixture comprising spacers disposed between the lid and the tank creating a gap for the passage of air there between, a flexible strip, the flexible strip being a closed loop with a perimeter smaller then the perimeter of the upper, peripheral edge of the tank, the flexible strip being positioned around the tank and the lid sealing the gap and forming a substantially air-tight band there between, the flexible strip having air flow passages for allowing air communication with the tank interior and a hose connector having an inlet for connecting and allowing air communication with the air flow passages of the flexible strip and an outlet, the exhaust fixture further including a blower connected to the outlet for the withdrawal of ga

Abstract: An exhaust fixture adapted to be connected to a toilet, the toilet having a bowl, a water tank having a normal amount of water therein and an upper, peripheral edge, an overflow pipe located within the tank, and a lid adapted to fit about the peripheral edge of the tank; the exhaust fixture comprising a flexible hose for the passage of air therethrough, the flexible hose having first and second ends and a length proximate the perimeter of the peripheral edge of the tank, the flexible hose adapted to be configured about the peripheral edge of the tank and having a sealing member for sealing the flexible hose about the peripheral edge and a hose connection having an inlet for connecting and allowing air communication between the ends of the flexible hose and an outlet, the hose connection adapted to be configured about an upper edge of the tank and having a sealing member for sealing the hose connection about the upper edge, the exhaust fixture further adapted to be configured to receive the lid such that the f
