Abstract: A process for the preparing agrochemical intermediates of formula (I): ##STR1## wherein W is (CH.sub.3 O) CH.CHCO.sub.2 CH.sub.3 or CH.sub.3 O.CH.dbd.CCO.sub.2 CH.sub.3 ; Z.sup.1 is a halogen atom; and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, acetoxy or acyl; the process comprising the steps of:(a) reacting a compound of formula (II): ##STR2## wherein X, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined above, with a compound of formula ROCH.sub.3, wherein R is a metal; and,(b) reacting the product of (a) with a compound of formula (III): ##STR3## wherein Z.sup.1 and Z.sup.2 are halogen atom. A process for the preparation of compounds of formula (II) and compounds of formula (II) themselves. A process for obtaining, in substantially pure form, a compound of formula (II) wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are all hydrogen.

Abstract: Compounds of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, acetoxy or acyl, and processes for preparing the same.

Abstract: A sealing ring assembly consists of (i) a preferably unreinforced sealing ring (ii) a harder supporting ring adjacent an axial side of the sealing ring and having lips extending axially to overlap the sealing ring at both its radially outer and inner peripheries, the radially inner lip being axially shorter than the radially outer one, and (iii) a bearing ring separate from the supporting ring. In a double-acting assembly there are two rings (ii) and (iii) arranged successively and respectively at each axial side of the sealing ring.
