Abstract: A centering device for positioning articles (33) for segmenting by passage through a cutter mechanism (18). The device comprises a plurality of spring members (31) positioned edge-to-edge around the feed line (26) with each spring member having a depending end (31A) positioned to contact and deflect each off center article towards the feed line for proper centering such that passage through the cutter mechanism will render equal sized segments.

Abstract: An apparatus for the ultrasonic measurement of cryogenic or high viscosity fluid flow provides for precooling and symmetrical flow in the measuring run of one of two coaxial inner and outer cylinders. A baffle in one of the cylinders directs fluid flow so as to encircle the measuring path cylinder thereby cooling it and reducing heat loss and flashing against the walls. Symmetrical entry and exit of the fluid flow in and out of the measuring cylinder eliminates the effects of velocity gradients on the ultrasonic measuring signals. Inlet and outlet ports are located perpendicular to the coaxial cylinders allowing a longer measuring run without requiring a similar interruption to the pipe system being monitored.
