!he c1111cellat1on of Cla1m 9 leaves cmJ,y Claia 14 re~ected on 1ta 

merits, and reconsideration ot this rejection 1a respeotf'ul.]Jreqnested. 

It, aa the Exaainer suggests, the code tape of cart1er or Vernam 

be cOlUl!dered graphic !nf'orllaticm. (and this appe&rB to be without 

d1ct1onar7 ean.ct:!.on) • where then is the eamouf'lage message, and 

how are the two elements {measages) acamied? .Ac1aial~, both reteraces employ one ke7board transmitter and one tape transmitter. 

Farthe1'1!102!'8,, :1D both pa.tents, the 1mpulses o~ two aeries occllr 

•bniltaneous~ 01" s,ynchronouaJ.7 ~ and this• aa waa po5.nted out bT 

the Applicant 1n an earlier amendment~ 1a necessarr 1n a Baudot 

qstem. !Ima, Cartier states (page 2,. lines 6S ... 73) that the tra.vel 

ot the Jce7irlg strip :la etf'ected automatical.1¥ upon each rotation o~ 

m-usb D.J.1 and Vemaa assumes (pp 81 lines 20-.'99) that the letter 

B ill !n. the tape transmitter when the letter .l ilJ being transaitte4 

trm the k8.J'boal'd. 

In Applicant's invention• there 18, o~ course, no necessary time 

relaticmship between the impulses cf" the •message• series and the 

:tmpul.aes or the "cn:.outlage• aeries.. It would be a rare occurrence. 

in :tact• tar &IQ" message impulse to be iidtiated at the same instant 

u a camouf'lage im.pulse, and mu.ch JllOr8 rare tor the duration of one 

nch 1mpulse to be an even multiple ot the duration ot the other. 

It appears possible that the Euminer read 9nonB1J1Chronous• aa 

11mm.1dent1cal" 1 as on this basis the ref"erences would seem to app:q • 

whereas, it •noneynchronoua• be proper]¥ construed to relate to time 

alone, the retei-ences seem not pertinent.
