Dve Marker.
Ome dye-oirker container is located in the vent passage
just below the sampler container; two moore are located on the botton side of
the base plate.
The marker compound consists of equal parts by weizht of
pelsechylene glycol (carbowax) and fluorescein disodium salt.
Fluorescein
is acded to the mited carbowax and this mixture is poured into the containers,
(Water solcble carbowax dissolves slowly in salt water.
These con-
taizmers continwe to meter dye for 24 hours.)
Flashing Lizhe.
Since recaw-r; cf the nose cones from the ocean was
schaduled co be made at cight, the flashing light was added to aid recovery.
This is a 30-volt, JOwatt bulb, potted in plastic ard mounted on top of the
Saspier container.
Its battery supaly and flasher circuit are located in a
watartight box oa the top side of the base plate.
The light flashes once
eaca second and lasts for 35 hours.
BF Homins Beacon,
Primary aids to recovery are UHF beacon transaitters
in che 266.5-ac to 2G4.5-me grequency range.
Specifications of the beacon
are:
Size
3 x 1-5/8 x 7/8 inches
Weight
T omces
Power Supply
two 33-volt, 3-amp/hour aercury batteries
Peak Power
1 watt
Averaze Power
100 nillivatts
Audio
1000 cps
Life
4O hours
Operation of the beacon is based on AM reception.
However, during the ap-
proxi=ataly l0O-aicrosecond period of each audio cycle that the beacon is
traamitring, the carrier will shite 150 to 1500 ke.
A shift of at least
150 ac is necessary, since the direction-finding equipment used in conjunctise with the beacon is erystai-concroiied ana tunable in 100-‘c steps.
