Oxygen Filling Connections
These connections provide all of the valves,
gages, and couplings needed for charging Parr
oxygen bombs from a commercial oxygen tank
under manual control. They are made in three
styles which are identical except for the
coupling on the bomb filling hose. All units
fit a standard 1A oxygen tank having a CGA
540 outlet with a right-handed thread. Two
pressure gages are provided. The larger gage
graduated from 0 to 55 atmospheres
shows the pressure to which the bomb
has been charged, while the smaller gage
shows the available pressure in the
supply tank. Gas flow to the bomb is
controlled by a needle valve in the gage
block. There is an automatic relief valve to prevent
over-charging during the filling operation.

Autocharger
The 1841 Autocharger provides an electronic control system
with a tank pressure regulator for filling an oxygen bomb rapidly
and conveniently without operator attention. Operations with the
Autocharger are completely automatic. The operator simply
pushes a button to start the filling sequence. Filling then
proceeds automatically to a pre-set pressure. Dual safety provi-
sions are built into the system to prevent an overcharge. Bulletin
1841 provides additional details.

Ignition Unit
These units provide the proper
electric current for firing a Parr oxygen
or sodium peroxide bomb from a 115
or 230 volt line. Each carries a push
switch, pilot light and output binding
posts for connections to 7 or 10 cm
bomb fuses. Connecting cords must be
ordered separately.
