    Abstract: This invention relates to a MEMS detonator, in particular the production of MEMS scale detonators via the use of a microreactor (3). The invention further lies in a reproducible manufacturing method of MEMS scale detonators, for use in safety and arming units (SAU), which are used in warheads and munitions. A warhead comprising a MEMS detonator may find particular use in increasing the IM compliance of munitions. The method involves the use of high pressure input of two solutions (2, 2a) into a microreactor (3) to form an in-situ precipitation reaction, which furnishes an initiatory (ι.e. primary) explosive, wherein the explosive and supernatant liquid is directly fed into a microchamber, using the microcavities in the septum as a MEMS sieve to retain the explosive and form a MEMS detonator.

    Abstract: An oil and gas welI shaped charge perforator capable of providing an exothermic reaction after detonation is provided, comprising a housing (2), a high explosive (3), and a reactive liner (6) where the high explosive is positioned between the reactive liner and the housing. The reactive liner (6) is produced from a reactive composition which is capable of sustaining an exothermic reaction during the formation of the cutting jet. The composition is a pressed i.e. compacted particulate composition comprising at least two metals, wherein one of the metals is present as spherical particulate, and the other metal is present as a non-spherical particulate. There may also be at least one further metal, which is not capable of an exothermic reaction with the reactive composition, present in an amount greater than 10% w/w of the liner. To aid consolidation a binder may also be added.

    Abstract: A method of nitrating electron-deficient carbocyclic or heterocyclic aromatic compounds such as pyridines, diazines and triazines and benzenoid aromatics having electron-withdrawing substituents involves first reacting the aromatic species with a sulphilimine species or with the corresponding N-alkali metal salt thereof to generate an N-(hetero)aryl-S,S-dialkyl, diaryl or alkylarylsulphilimine derivative. This intermediate may then be readily oxidised under relatively mild conditions using a peroxycarboxylic acid such as m-chloroperbenzoic acid, peracetic or peroxytrifluoroacetic acid. Good yields of nitrated products are obtained including some previously unprepared. The novel N-alkali(alkylaryl)sulphilimine reagents are prepared by reacting an alkali metal hydride, an alkali metal hydrogenous base or an alkyl lithium with the corresponding sulphilimine. Preferred salts are the N-lithio types and the preferred sulphilimine is diphenylsulphilimine. Where the salt is used reaction should be in an aprotic solvent but if the sulphilimine per se is the reagent a polar solvent is used.
