Abstract: The present invention provides a smoke expulsion system for emergency use in the event of a fire in flight on a transport aircraft. The invention provides a pneumatic mechanism electronically activated at the start of fire which will harness the differential in air pressure at cruising altitudes above 10,000 feet and by means of nozzles, valves, and flexible tubing will concentrate the smoke from the fire area into the chamber of said mechanism and expel smoke outside the aircraft. When the emergency is over, the mechanism is shut and the flight continues till a safe landing is possible.

Title: Aqueous immunologic adjuvant compositions of monophosphoryl lipid a
Inventor: CRANE R THOMAS
IPC: C07H13/06
Filed: 1998-04-01
Granted: 2011-02-08
Abstract: An aqueous adjuvant composition comprising an attenuated lipid A derivative and a surfactant or surfactants enhances the immunological response in a warm blooded animal to a protein antigen. Attenuated lipid A derivatives useful according to the subject invention include monophosphoryl lipid A and 3-O-deacylated monophosphoryl lipid A. A surfactant or mixtures of surfactants are dissolved in a solvant. 1,2-Dipalmitoyl-sn-glycero-3-phosphocholine is a preferred surfactant. The dissolved surfactant is added to an attenuated lipid A derivative to obtain a mixture. The molar ratio of attenuated lipid A derivative to surfactant in the mixture is about 4:1. The solvent is evaporated and water is added to the resulting film. The suspension is sonicated in a 60 °C water bath until it becomes clear. Animals administered the adjuvant formulation exhibited increased antibody responses to a given antigen as well as displayed enhanced lymphocyte proliferative and cytotoxic T-lymphocyte responses. Intranasal administration of the aqueous adjuvant composition and an antigen stimulates the production of serum and mucosal secreted IgA.

Abstract: An air inlet is provided at the bottom of a vehicle to open downwardly. The air inlet is connected by a first tube to an air cooler for a PDU and a down converter. A fan for inputting the flow of air and turning its direction 90 degrees is connected at the downstream of the air cooler.  The fan is further connected by a second tube to an exhaust outlet. The air inlet is located above a fuel tank thus to prevent any object jumping up from the road surface from straightforwardly entering the air inlet while the vehicle is running. The exhaust outlet is located above a silencer and can thus be prevented from being frozen in the winter.  Using the above arrangement, the present invention embodies an air-intaking and exhausting apparatus in an air cooling system for air cooling the PDU and the down converter at higher efficiency without the help of the air cooler mounted in the interior of the vehicle.

Abstract: This invention discloses a novel floating ball or shuttle within double funnels, which will be able to form a seal at both the upper and lower funnel spout points of the double funnel float valve in liquid supply and liquid disposal systems. The ball rests at the lower funnel spout point when there is no liquid in the valve, preventing gases from passing through the valve. When a liquid is in the valve, the ball floats and allows liquid to pass through the lower funnel spout. The ball prevents liquid from being forced back up the valve by sealing the upper funnel spout when the level of liquid is sufficiently high.
