An impact piston is provided which is reciprocal in the housing to deliver successive impacts to the anvil. The piston and housing form a forward chamber of variable volume. The mechanism further includes a control assembly comprising a forwardly extending sleeve which slides within a rear space of the impact piston to form a rear chamber of variable volume, and a central passage within the sleeve for continuous supply of compressed air through a forward opening of the sleeve into the rear chamber and therefrom into the forward chamber through a port in a side wall of the rear chamber of the impact piston. The sleeve has an aperture in its side near the forward opening and is provided with a valve operable by twisting of the sleeve. Operation of the valve controls forward and reverse movement of the mechanism. The sleeve has a circular collar which rotationally slides inside a surrounding circumferential bush and enables the sleeve to be located with the aperture open or closed by the valve.

Abstract: L'invention concerne une stratégie alternative d'expression de gènes étangers induite par baculovirus consistant à utiliser les promoteurs de gènes viraux de baculovirus immédiats-précoces ou tardifs-précoces afin d'obtenir l'expression continue de gènes étrangers dans des cellules d'insectes transformées de manière stable. Les promoteurs de IE1 ou de 39K provenant du virus de polyhydrose nucléaire Autographa californica peuvent induire l'expression continue d'un gène étranger dans une cellule d'insecte avec les avantages d'un traitement plus efficace ainsi qu'une dégradation minimale de produits protéiques recombinés. Les baculovirus recombinés sont hautement infectieux in vivo et résistants à l'inactivation dans la nature. Par conséquent ce virus s'avérerait très efficace comme système de libération de pesticides.
