Abstract: An apparatus for producing a highly combustible fuel comprising a reactor chamber maintained under negative pressure, a nozzle for spraying an atomized fuel under pressure into the reactor chamber forming atomized droplets, a nozzle for introducing air into the reactor chamber to mix in a reactor zone with the atomized fuel for supplying a high voltage electrical potential differential, including at least one electrode located in the reaction zone, for providing an electrical charge to the atomized droplets, and means for passing the resulting atomized fuel and air to the manifold of an internal combustion engine.

Abstract: A highly combustible fuel which exhibits low exhaust pollutants is developed by exposing an atmosphere of a gaseous hydrocarbon fuel, for example, gasoline, to a source of energy such as an electrical potential difference, ultra-violet radiation, microwave radiation or laser radiation. The combustible fuel can be fed directly to the cylinders of an internal combustion engine. It is clearly visible in the flask as being whitish silvery grey in color. The combustible fuel can also be condensed and the condensate employed as a fuel.

Abstract: A method and apparatus is presented for cleaning engines which includes processing a previously condensed process fuel and passing it through a vessel which is provided with electrodes that provide a negative electrical charge to the molecules of the liquid fuel. The electrically charged fuel is then connected through the fuel line to the engine to be cleaned, and the engine is operated for approximately half an hour utilizing the electrically charged fuel whereby carbon deposits and other contaminants are cleaned from the engine and the catalytic converter. The vessel has an inlet and an outlet port, a pressure regulator at the inlet port for permitting air under pressure to enter into the vessel to pressurize the liquid fuel and an outlet port for exhausting the charged fuel into the engine to be cleaned.

Abstract: A method for vaccination against haemorrhagic dysentery of pigs with a vaccine including an effective quantity of inactivated and adjuvant-containing Serpulina hyodysenteriae antigen which is administered intradermally, it being possible for the vaccine to be especially formulated in a dose volume of between about 0.1 and 0.3 ml, especially of the order of 0.2 ml. A vaccination kit for administration of the vaccine may include, for example a pressurized jet administering apparatus, designed for the intradermal administration of individual doses of vaccine and combined with a supply source containing a vaccine of this type.

Abstract: The present invention relates to a rotary-wing aircraft, especially such as a helicopter, of the compound type including:a fuselage (2),fixed-wing elements (6) arranged on either side of said fuselage (2),at least one main rotor (4),an anti-torque rear rotor (9), anda rear thruster propeller (14), arranged at the end of the tail boom (8) of said fuselage (2).According to the invention, said rear thruster propeller (14) has a shroud (15).

Abstract: A saucepan is provided which includes a base (1) delimited at its periphery by a rim (2), and a plate (4) arranged against the inner surface of the saucepan's base. The saucepan further includes a device which moves the plate away from the base. This moving device is actuated by a control member and is located between the plate and the base.
