Improved equipment and technique for high pressure sap displacement impregnation of natural round wood

IRG/WP 309

C G W Mason, F B Shorland

Hitherto the main problem in the practical application of high pressure sap displacement impregnation (HPSD) has been in devising a satisfactory cap. Such a cap must be easily fitted to different size log ends to give a leak proof seal. The present contribution describes a new type of cap and sealing system designed to meet these requirements.
