Abstract: Packaging of certain products like cheese is usually done in a vacuum without the presence of heat. Heretofore, a first vacuum was necessary to knit the curds together and to compact the cheese. A second vacuum was then employed to remove air which returned to the package. The present method eliminates the need for the second vacuum. A heat sealable package, containing cheese, and having a tortuous vent passage is subjected to a vacuum. As a full vacuum is achieved, air within the chamber and the package is exhausted. When the chamber is returned to atmospheric pressure, the tortuous seal collapses to form a temporary seal. At the same time, the plastic bag collapses around the cheese which causes the curds to knit together, and compact the cheese. While still in the sealed condition, a permanent heat seal is made across the tortuous vent passage.

Abstract: In the on-site manufacture of nipples of relatively short length for joining pipe sections in a conduit system, spacer pins and spacers are selected to achieve a user-determined displacement between an end stop and cutting element of a pipe groover used for cutting external annular grooves along the pipe stock. The use of the spacer pins and spacers allows the grooving tool to be displaced at measured displacements from a selected end of the pipe stock while providing a visual gauge to the user of such displacement.In the fabrication of these nipples, the end stop/yoke is positioned abutting a selected end of the pipe stock thereby positioning the cutting element where a first groove is cut. Upon selection of a combination of spacer pins and/or spacers the end stop is again positioned to abut the selected end of the pipe stock thereby positioning the cutting element where a second groove is cut.
