Abstract: The present disclosure relates to a well-stimulation apparatus with one or more elongated tie rods, at least one sealing assembly coupled to the one or more tie rods, and a stimulation material for generating a pressure event. The pressure event can stimulate a targeted portion of a geological formation that is positioned about an isolated portion of the wellbore. The pair of sealing assemblies are actuatable between a dormant condition for moving the well-stimulation apparatus in a wellbore and an active condition for defining the isolated portion of the wellbore.

Abstract: An aircraft seat has a frame assembly onto which is attached a shaped front cover by means of clips, each having a socket component and a plug component. The plug and socket components are repeatedly engageable and disengageable, enabling the front cover to be repeatedly removed from and refitted to the frame assembly, for example for cleaning of the front cover. The clips ensure accurate and precise fitting and location of the seat cover with respect to the frame assembly.
