Abstract: A solid formulation of an agrochemical is prepared by forming a melt containing at least one agrochemical and at least one thermoplastic binder having a melting point or glass temperature of greater than 35° C., briquetting the melt by dividing it into drops in a first step and solidifying these drops by cooling in a second step, characterized in that the melt additionally comprises a liquid non-volatile solvent for the agrochemical.

Abstract: An electrical power generation assembly (10) comprises a main body (12) having a low density to provide lift and wind driven means (18) on a surface of the main body (12) to generate electrical power. The main body (12) has a prismatic shape and has a part-circular, or a part-elliptical, cross-section frontal region (27). The main body (12) has a first distance (B) from a central plane (P) of the main body (12) to a line of intersection (Z) between the frontal region (27) and the remainder (26) of the main body (12). The main body (12) has a second distance (A) from the line of intersection (Z) between the frontal region (27) and the remainder (26) of the main body (12) to a line of intersection (T) between the most upstream points of the frontal region (27) and the central plane (P) of the main body (12). The ratio of the first distance (B) to the second distance (A) is equal to or more than 0.5 and equal to or less than 5.

Abstract: In order to achieve greater operational efficiency a propulsive arrangement is provided in which a relatively large number of small propulsive assemblies 9; 31, 32, 33 are provided in aircraft structures in particular the wing 7; 30. The assemblies 9; 31, 32, 33 comprise a flow path within which a compressor 39, 43, 47 is positioned to propel an air flow for propulsion. The compressors 39, 43, 47 are powered by electricity from an electricity generator 8 and possibly supplemented by solar cells or fuel cells or wing tip turbine generators 11. The assemblies 9, 31, 32, 33 are small to allow easy removal for maintenance and repair.
