Features of vacuum impregnation of optical fiber
Assembling in Mechanical Engineering and Instrument-Making, 2022The article discusses the features of impregnation of the fiber contour during the manufacture of a sensitive coil of a fiber-optic gyroscope. The technological process of impregnation has been developed. The results are analyzed, further directions of work are proposed.

Vacuum impregnation of firming agents in red raspberries
Journal of the Science of Food and Agriculture, 2018AbstractBACKGROUNDRed raspberries are a delicate and highly perishable fruit with a fragile pulp tissue. In this study we used vacuum impregnation (VI) methods to incorporate pectin and calcium chloride into whole red raspberries to improve their firmness.

Experimental Determination of the Dynamics of Vacuum Impregnation of Apples
Journal of Food Science, 2007ABSTRACT: Vacuum impregnation (VI) is a food processing method by which air and native solution are removed from porous spaces within a food and replaced by an external solution. In this study, an experimental device based on a previous design was built, including some modifications, in order to investigate the

USE OF VACUUM IMPREGNATION FOR MINIMALLY PROCESSED FRUITS AND VEGETABLES
Acta Horticulturae, 2010Vacuum impregnation (VI) is a recent development in the osmotic treatment of foods. VI of a porous product consists of exchanging the internal gas or liquid occluded in open pores for an external liquid phase by the action of hydrodynamic mechanisms promoted by pressure changes.

Impregnation of difficulty wettable substrates by exposing the dry substrate to a sufficiently low atmospheric pressure to remove occluded air, followed then by immersion in aqueous baths with a final return to atmospheric pressure, gives thoroughly saturated substrates in a fraction of the normal time.

Possibilities Of Vacuum Technology I‐Vacuum Impregnation II‐Vacuum Transfer Printing
Journal of the Society of Dyers and Colourists, 1973The use of subatmospheric pressures as an aid to the transport and transfer of dyes to textile materials is described under the headings of vacuum impregnation (Part I) and vacuum printing (Part II). The noteworthy advantages demonstrated in the laboratory and in bulk, and the machinery developed for the use of vacuum, rely essentially on the removal ...

A decade of vacuum pressure impregnation
1983 EIC 6th Electrical/Electronical Insulation Conference, 1983A Manufacturer of Electric Motors or a Sevice Shop is faced with a major investment in capital equipment and tooling to produce an insulation system for form wound stators which will resist severe moisture and chemical contamination. During the 1960's, Vacuum Pressure Impregnation {VPI) using 100% solid resins was a new process being introduced to the ...
