Abstract: An article of manufacture for shielding the interior of each of a succession of container bodies from impurities present during fabrication is disclosed. The article has a base plate having a distal end and a first impurity deflection member extending downwardly therefrom at an obtuse angle with the base plate. The first impurity deflection member is adapted to be disposed adjacent to a forward open end of one of the succession of container bodies during a predetermined sequence of fabrication to prevent impurities from passing into that container body through the forward end thereof.

Abstract: A flow indicator for measuring fluid flow through a pressure cooking vessel bleeder. The indicator comprises an elongated housing having a fluid passage formed therethrough which is vertically secured to the bleeder so that a fluid flow connection exists between the bleeder and a fluid inlet opening into said passage. An indicator ball is disposed within the passage and is suspended in the fluid flow emitting from the bleeder. A means for determining the vertical position of the ball within the passage is also provided which, in a preferred embodiment of the invention, comprises a measuring device such as a photoelectric cell circuit.
