Abstract: An electronic tracking tag 10 may be attached to various types of physical assets to assist in asset identification. The plastic material tag body 12 includes a receiving cavity 60 therein so that a drawer 14 and an RFID transponder 16 may be slid into the receiving cavity and mechanically locked in the inserted position within the receiving cavity. A visual display cavity 54 is provided on the tag body, and a display label 56 may be selectively positioned on the tag body. The tag body with the electronic transponder therein may be secured to the physical asset by screws or other conventional securing members 46 positioned in respective securing holes 42, 44 provided in the tag body. Alternatively, one or more flexible straps 18, 19 may extend through a respective tie down hole 46, 48 in the tag body for strapping the tag body to the physical asset.

Abstract: A hydrocyclone separator (10) has an outer housing (12) including an upper housing portion (14) and a lower housing portion (16). Upper housing portion (14) has a cylindrical chamber (22) and an involuted entrance (20) to cylindrical chamber (22). A vortex finder tube (24) has a flaring lower end portion (29). A solid core (34) is mounted within finder tube (24) and extends downwardly from finder tube (24) a distance at least equal to 11/2% times the inner diameter of the entrance orifice or opening (30) of finder tube (24). The outer peripheral surface (40) of solid core (34) tapers downwardly and is generally parallel to the inner peripheral surface (44) of lower tapered chamber (46). A strong interface (48) is formed between the downwardly extending outer vortex and the upwardly extending inner vortex with minimal turbulence and intermingling of particles between the inner and outer vortices.

Abstract: A mechanical seal assembly having multiple compression spring assemblies that are used to bias a stationary seal into sealing engagement with a rotating seal, the springs in the spring assemblies being supported on their internal diameter and having their outside diameter visible for their entire length, each spring assembly further including a releasable, expendable clip that serves to preload the two seal faces against one another, limits relative axial movement between the stationary and rotating seal assemblies, and coaxially aligns the stationary and rotating seal assemblies.
