Abstract

1275449 Operating pneumatic tools under water HOLMAN BROS Ltd 7 Dec 1970 [12 Dec 1969] 60779/69 Heading E1H [Also in Division F1] A pneumatic tool 11 submerged under water is in a closed pneumatic circuit with a motor 15 driven pump 14. The motor 15 and pump 14 may be enclosed in a submerged vessel 10 (e.g. with an access panel 20 and a control panel 21) together with a reservoir 16 in the tool 11 (e.g. a rock drill) supply line 12, and a filter/dryer 17 in the return line 13, the circuit between the filter/dryer 17 and the pump 14 being via the interior of the vessel 10. The pump 14 may be cooled by a heat exchanger 19. The motor 15 may be supplied with electrical power either from batteries in the vessel 10 or from the water surface 22. Gas leakage from the circuit may be replenished either from a high pressure cylinder in the vessel, or from a pump 31 and reservoir 32 in a barge 33.
