Abstract

1,076,787. Pneumatic power transmission. DENTALTECHNIK POTSDAM VEB. Jan. 18, 1966, No. 2285/66. Heading FIX. In a pneumatic switch control system for a dental drilling machine; the pneumatic system is automatically vented to atmosphere when the drilling instrument (7), Fig. 1 (not shown) is placed on support 8, Fig. 3. A flexible operating tube 12 is connected to a diaphragm amplifier 11 coupled to a mercury switch 13 which controls a motor 15 via a control unit 14. When the drilling instrument is in use the valve 16 is held closed by spring 18 thus allowing operation of the diaphragm amplifier 11 by foot pressure on tube 12.
