RECORDING ACCUMJL TI:3G COdr.TERS
This proposal is submitted in response to and conforms
0 with specifications as outlined in Code 822 File 3900,
The purpose of this product improvement is to provide
an er:codin neasurer~ent system with electronic transistorized
recor:ing accu:.iulating counters,
"'asically, the system will, consist of a rack (Figure 1),
in accordance ,,i,th the block Diagram (Figure 2). The system
operation will he as follows:
Encoders attached to the ;. and Y lead screws will feed
pulses equivalent to 2 1/2 microns at-the film plane into solid
state up-down counters. Upon operator demand, this count in-
for:1ation together with the three (3) digit event counter data
:-.ill be processed, converted, coded and recorded on an eight (8)
i_evel punch tape in a BCD coded A 1.00 hole patch board will
provi ?e program, information flexit)ilityo Convenient remote
controls Pill perrit the operator to zero reset all counters, as
well as automatically record all data,

DESCRIPTION OF EQUIPMENT AND WORK STATEMENT
1) install (4) 1000 count per revolution encoders, Data
Tech Magnetic Iricrosyn type,, 1.5 diameter to eliminate rework
of base frame and carriage castings. 1000 count/rev, will pro-
vide a least bit; measurement resolution of 2 1/2 microns when
decoding 2 1/2 nilimeter pitch screws. Encoder count rate of
20 KC is expected to be more than adequate for 10,000 bit per
second rate equivalent to 1 .nch/second carriage travel,
2) (4) 6 decade bi-directional high speed counters em-
ploying transistorized plug in decade boards and mounted for
maximum heat dissipation together with accessability for easy
maintenance. True negative and positive + indication is provided
on nixie tube numeric displays, (one for each coordinate axis),
3) Event Counter - 3 decade, solid state counters with
visual readout and reset-preset capabilities,
? 4) Input - Output sequ.ncors, with decoder logic, punch
driver, converter, start-stop print logic and remote control
provisions with all necessary interconnecting cables,
5) Patch board with patch wires and interconnecting
wiring (50 input: to 50 hole output), see Figure 2'. This is in
accordance with the above referenced specifications,
'STATINTL 6) Tape punch
compatible with 8 channel Dura-BCD code.
7) Console to house the above items 2, 3, 4, and 5. This
console contains, a blower for cooling, and contains racks on
slides to allow accessibility for maintenance.

8) An interlock circuit will be provided so that power to
the X and y drive is removed while readout to,the tape punch is
in progress.
