Abstract: This invention combines specific new and novel equipment with the equipment of a conventional combustion system for the use of liquid fuel oil to create a new system which converts the liquid fuel into gas and operates as a gas burner rather than as a liquid oil burner. The new and novel equipment thermally cracks liquid hydrocarbons into gaseous hydrocarbons which have substantially lower molecular weights than the liquids from which they were cracked. In the system the burner apparatus itself is modified to burn gas rather than liquid. In this new system the fuel burned does not consist of vapors of the liquids supplied to it but instead operates on the products of decomposition derived from the liquids.

Abstract: An arrangement for preventing the capsizing of trimaranes, and to facilitate their righting, comprising a main hull, two stabilizing hulls pivotally connected to the main hull by a pair of arms and further including a pair of extensible elastic members to restrain the upward movement of the stabilizing hulls and a plurality of flexible, non-extensible members to restrain the downward movement of the stabilizing hulls.
Abstract: This device for automatically releasably hanging and holding against lateral oscillation load carried under aircrafts has load suspension hooks and holding members preventing the lateral oscillation of the load which project very moderately from the underface of a closed casing containing the actuating mechanism. This mechanism includes in combination linkage detents and springloaded devices disposed on either side of each load suspension hook. A certain delay is introduced into the action whereby when the load is lifted for engagement with the hooks, these are actuated to their load-supporting position and release with a predetermined time-lag the linkage holding the load against lateral oscillation to their operative position. To this end, each pivotally mounted hook is connected via a spring-loaded piston-and-cylinder actuator to a rocker controlling the movement of wedge members controlling in turn a lever supporting the holding members.

Abstract: A self-closing structure has a tube having a free end surrounded by a funnel shaped end of a cylinder supported on a diaphragm capable of being mounted on the open top of an elastically yielding container and upon compressing said container forcing the contents thereof against said diaphragm the funnel shaped end moves along said tube allowing said content to be extruded and upon the release of the container said funnel shaped end returns below said tube free end and is closed thereby. The release of the container due to its elastically creates a suction thereof drawing air down said tube into said container. A valve can be mounted below said tube normally closing the same, but being opened only for the suction in said container.
Abstract: A complete system for a pollution free engine, in which liquid fuels are metered into a device attached to the engine, in which device the liquids are changed into gaseous fuels (not vapors), and the gases so produced are mixed with air so that they can be combusted perfectly in the engine without the production of any polluting emissions. The system includes the three elements required: a device to change liquid fuels into gaseous fuels, a valving system to meter the supply of liquid fuels, and a carburetor to effectively mix gaseous fuels with air.
