Abstract: An electrostatic spraying device for use in spraying liquids having resistivities of the order of 5.times.10.sup.6 ohm.multidot.cm and viscosities of the order of 1 Poise at a spraying rate up to at least 4 cc/min (especially paint formulations) is provided with an annular shroud (112) of semi-insulating material (e.g. bulk resistivity of the order of 10.sup.11 to 10.sup.12 ohm.multidot.cm) which is electrically connected to a high voltage generator (126) for supplying high voltage to liquid emerging at the outlet of the nozzle (114). In this way, a voltage is established on the annular electrode (126) which is of the same polarity, and substantially the same magnitude, as the voltage applied to the liquid thereby modifying the potential gradient in the immediate vicinity of the nozzle outlet so as to allow the use of the high voltage needed to effect efficient spraying of liquids having the specified resistivity and viscosity at flow rates up to at least 4 cc/min.

Abstract: An impact sensitive high temperature detonator is disclosed. The detonator comprises an initiator charge of lead azide next to a thin casing wall at the input end, and a mass of finely divided refractory material adjacent to the initiator charge. The detonator can be initiated by a rounded firing pin, which indents the casing wall without puncturing it. In the event of misfire, the casing will remain intact, which facilitates safe removal of the detonator.

Abstract: A method of preparing certain 2-halo-5-methylpyridines, useful as herbicide intermediates, is presented starting from acyclic pentenes. The pentene is difunctionalized, e.g., by making the epoxide, and is then reacted with a nitrogen source to close the ring. The nitrogen-containing 6-membered heterocycle may then be aromatized readily to produce the 2-halo-5-methyl-pyridine desired. Also part of the invention are novel acyclic and cyclic intermediates used in the process.
