Information on the cold temperature capacity of mercury batteries
for use in HRT-2 beacon transmitters was given to the customer. While the
life of the presently used cells appears to be extremely short when tested
without any housing in a laboratory cold box, this type of test does not
simulate actual operating conditions. This is because the bare cell in
the cold box is cooled to the actual ambient by the circulating air while
the battery in the unit is insulated and protected from ambient conditions,
and the heat produced by internal heating will keep the battery at a higher
than ambient temperature. In the case of the R6-42R cell now being used,
the bare cell had a life of 6 min. to a .6 volt end point with a .5 ohm
load when the cold box temperature was 32?F. When the battery composed of
RM-42 cells is tested inside the beacon housing with the beacon as a load
the battery had a life of three hours at 32?F when the transmitter drew
1.7 amps at 15 volts from the battery, corresponding to a per cell load
of .59 ohms.
is investigating the possibility of having a battery pack
made up of special cold temperature cells. Since these cells have a
different form factor than the RM-42 cells the resulting pack may have
a different shape than does the presently used battery. Either a 12 cell
or 18 cell battery will be used depending on the internal impedance of the
new cells. If a low enough impedance is obtained at low temperatures only
12 cells will be needed to provide the required terminal voltage when the
battery is providing the proper load current* A 12 cell battery will fit
into the present battery compartment in the HRT-2 beacon. The cost of a
new battery pack would be approximately $50 for a 12 cell pack and. approx-
imately $65 for a 18 cell pack. The number of cells will have to be de-
termined after sample cells are received and tested

The customer will decide whether or not a new battery pack should be
provided for the beacons. Regardless of the decision, the remaining 18
units to be delivered on T I 28 will not be revised to permit use of a
larger battery pack. will provide the customer with data comparing
the presently used battery and the new cold temperature packs using data,
from both Mallory and tests conducted at
The customer requested that a crystal hold-down clamp be used even
though the socket provides a great amount of tension on the pins. Another
request was to include a spare crystal in each transmitter. This crystal
will also be in a socket having a hold-down clamp. For the

being built on T. O.. 32 the same frequencies will be used as are being
used on the 18 units to be delivered on T. O. 28. These frequencies are:
1,620 1,650 1,680 1,725 and 1,750 kilocycles. There will be 32
units on each frequency. The customer requested that the spare crystal
in each unit be at least two channels removed in frequency from the crystal
in the oscillator socket.
A dis u si was held regarding the customer's request for a proposal
to have prepare man drawings on T. O. 28 in place of
the engineering drawings that originally proposed to provide.
The discussion was concerned wi efinition of manufacturing drawings
and the possible delivery date for drawings. It was decided to define
the needed drawings as follows. ?
1. Parts List
The parts list would be the conventional information supplied with
engineering drawings indicating all manufacturers, manufacturers'
part numbers, tolerances and other information required to order the
standard cataloged items used in the equipment.
2. Engineering Drawings
Engineering drawings will show the construction, material and finishes
of all items unique to the equipment. This also includes drawings
showing modifications to standard items.
3.. Assembly Photographs
The assembly photographs indicate how components on the parts lists
and unique items are joined to make subassemblies. Other photographs
indicate how subassemblies are joined to make assemblies. The photos
have "call-Outs" on them showing the schematic reference symbol or
part number. Enough photos will be made to show all views necessary
to assemble the equipment.
4. Process Specifications
Process specifications are a step by step assembly procedure indicating
how eaeh component and unique item is assembled into a subassembly
and how the subassemblies are assembled to form the main assembly.
5. Test Specifications
a. Components
The test specifications for components will give any information
required above and beyond that indicated on the parts list to
select components for special characteristics for use in the
equipment.
b. Equipment
The test specifications for the equipment will list test procedures
and operating specifications that will define the acceptable per-
formance of completed equipment.

These definitions of manufacturing drawings and information will suffice
for the requirements on the HRT-2 beacon transmitters. The customer will
be advised by phone on November 16 when this information can be provided.
The customer stated that the proposal for the production of 160 HRT-2
beacons did not indicate the quantities of manuals to be delivered with
the units. It was agreed that one Test and Acceptance Manual and one
Field Instruction Manual would be sent with each HRT-2 beacon and in
addition 10 extra Field Instruction Manuals would be provided.
The customer asked what the proper method of wearing the back pack
was. Various methods of attaching and adjusting the straps were demon-
strated. It was decided that modifications to the carrying bag are needed
to strengthen the pack and make it more convenient to wear. The manufacturer
of the bag will be contacted and the necessary changes will be made in the
bags to be supplied with the 160 beacons to be made on T. 0. 32.
