    摘要: A pesticidal compound of formula I: ##STR1## in which formula: either R.sup.1 is hydrogen and R.sup.2 represents a cyclopropyl group or R.sup.1 and R.sup.2 each represent an alkyl group, which alkyl groups may be the same or different;Ar.sub.A represents an optionally substituted phenyl or naphthyl group;Ar.sub.B represents a phenoxy, phenyl, benzyl or benzoyl-substituted phenyl group which is optionally further substituted;the configuration of the groups Ar.sub.A --CR.sup.1 R.sup.2 and --CH.sub.2 Ar.sub.B about the double bond being mutually trans.Preferably Ar.sub.A is a substituted phenyl group; more preferably being substituted at the 4-(para) position by halogen, alkoxy or haloalkyl.Further provided is a process for the preparation of a pesticidal compound of formula I in which a compound comprising a moiety ##STR2## and a compound comprising a moiety Ar.sub.B -- are reacted together forming a link --CH.dbd.C(F)CH.sub.2 -- between ##STR3## and Ar.sub.B in the compound of formula I.

    摘要: A mole 1 for replacing an existing main, for example a cast iron gas main, with a new main. The mole 15 is of steel and is inserted into and along the existing main 94. The mole 51 has a front portion comprising a head 52 and a cylindrical body portion and a rear portion 53 having a clamp 54 for clamping a new main to the mole 51. The head 52 has a cutting face 55 for engaging the internal wall of the existing mole 51 therealong. The new main which in use is clamped to the mole 51 is towed along behind the mole 51 to replace the fractured old main 94.
