摘要： A removable filter for separating and filtering slurry liquid from solid particles includes one or more filter sections connected by a filtrate conduit. Each section comprises a plurality of vertical, hollow, sintered metal filter elements horizontally arranged across a manifold connected to a hollow filtrate conduit. The sections are vertically stacked and connected by the conduit(s) to form the filter which is removably secured in the slurry by means which permit it to be removed vertically up and out of the top of the reactor. This filter has a high surface area to volume ratio and is useful for removing the liquid hydrocarbon products from a slurry hydrocarbon synthesis reactor and can easily be replaced without having to drain out the slurry.

摘要： A down-hole hammer comprising a drill bit (10) and a drive collar (11) with an interconnection therebetween for causing rotation of the drill bit upon rotation of the drive collar. The drill bit (10) comprises a drill bit head (13) and a shank (19), the drill bit head (13) defining a cutting face (15) and having a circumferential shoulder section (17) adjacent the cutting face (15). The shank (19) extends from the shoulder section (17) in the direction away from the cutting face (15). The interconnection between the drill bit (10) and the drive collar (11) comprises a spline assembly including at least one spline (43) on the shoulder section (17) for mating engagement with at least one counterpart spline (63) on the drive collar (11) to provide a drive coupling therebetween while also allowing the drill bit (10) to slide axially within the drive collar (11) to perform a percussive action.
