VACUUM IMPREGNATION DEVICE Russian patent published in 1994 - IPC

FIELD: electronic engineering. SUBSTANCE: device has four-position turning drum with case rigidly secured by its base on each position of drum. Case serves to hold each section by its wire leads. Vacuum impregnation chamber is installed on bedframe for vertical reciprocating and engagement with base of case as with cover. Drying device is made in form of two leaves (upper and lower ones). Fitted on inner surfaces of leaves are porous flexibly-elastic linings with cells forming, when closed, an enclosed space. Section is placed in this space and first is treated with compressed air delivered to cell, and then is subjected to treatment by means of absorption pump connected with cell. EFFECT: enhanced reliability and increased capacity of device owing to combination of auxiliary operations and simplified design; enhanced quality of product owing to use of compressed air together with treatment by means of absorption pump and provision of uniform drying of each section in separate cell. 2 cl, 2 dwg
