DEVICE FOR TAKING AEROSOL SAMPLES FROM JET AND TONG IN BURNING PYROGENIC COMPOSITIONS AND FUELS Russian patent published in 1995 - IPC

FIELD: pyrogenic compounds. SUBSTANCE: device has stepping motor moving sublayer and electronic unit for controlling the stepping motor to carry out distant control start. The electronic unit maintains motor operation according to a given program, finishing off the exposure time period, rigidly fixing motor shaft during exposure time period and stopping after finishing off on cycle. Stepping motor shaft has rotary disk for laying sublayer and rotatably mounted to perform periodically unidirectional rotations and to be stop rotating when the capillaries are placed in front of the sublayer. The sublayer is made of electronic microscopic networks, glasses and fine-fiber filters fixed on the rotary disk in a given order. The number of the capillaries corresponds to the number of members composing the sublayer. EFFECT: enhanced effectiveness in registering finely divided particles of combustion products. 2 cl, 2 dwg
