Abstract: A fluid cleaning device includes a spheroid-shaped member defining an internal void. The spheroid-shaped member further includes a wall defining a plurality of apertures and at least partially surrounding the internal void and an inlet orifice that receives a cleaning fluid under pressure. A tubular nozzle projects from the inlet orifice and into the internal void to mitigate fluctuation of one of the internal pressure and flow velocity of the cleaning fluid within the spheroid-shaped member.

Abstract: A sanitary clamp with facing ring halves employs one or more threaded closure devices configured to avoid having any threads exposed to the ambient. A bolt member may have a stepped shaft with a first smooth shaft portion and a male-threaded tip portion. The latter may be the same or a smaller diameter. An associated nut member has a blind bore that extends from a first end of the nut, with a first smooth wall portion and a second female threaded bore portion. The second female threaded portion may have the same bore diameter, or the bore can have a stepped interior diameter with the second female threaded bore portion having a diameter smaller than the first smooth wall portion. A seal member or gland within the smooth wall bore portion closes off a space defined between said the tip portion of the bolt member and the female-threaded bore portion. Once installed, there are no threaded surfaces of the bolt member or the nut member that are exposed to the ambient.
