'0DNFIDENTIJl\L 

It :la usumed that Claim 2, in rlew of the amndments made to tho 

flP601fieat1on. will be CODB1dered allowable ae eoon as the drawillgs 

Cla1Jas 3 and 4 have been cencelled. 

Oldma 51 61 and 7 appear not to be mt tv" the pa.tent to ttorn, 

11705,641, except. that tho pe.tcnted d18cl.osure contains end contacts 

80l!lnl:iat like thoee 1n the claims. The patent on the other band shows 

neither indicators nor nitobes associated with each one thereof', and, 

or course, the circuits of' !'.om are entirel.;r dif'ferent trom those or 

Claim S. Bebo1"111 1.683,0721 llkewiae f'a1la to ab.ow the switch and indicator arra.neor:ient of tho .lppliCSllt. It will be JJOted that, accord• 

ing to Hebern, onl¥ the output is actuated (Page 4, lime 58 through 

?2}. Since the re.t'erenco f'd.le to •hon tho c1rcuit arrangement of' 

Cl.a1m S, upon which Claims 6 and 7 are hued, it 18 bellned that the 

latter two el.aims should not be ob.fectionable. 

Claim 9 hos been cancelled. 

With rega%'d to the objection to Claims ll and 12, Applicant admits 

'fibat 111Dat ccyptographs can be used tor purposes or authentication, but 

it wuld not bo accurate to eq that moat are espec~ adapted f'cr 

thie £'Unction. These cla:S.. clearl.7 point ant the novel t'ee.ture or 

Applicaht•s au.t."11.enticator, that being the circuit which al\llBYS produces 

the enciphered equivalent~ a pndeterminad input character. Lines Sl 

through SO ct Page lot the Scherbius patent, 1,657,411, it mq be noted, 

are directed to qnchronizat1on and to the prevention or garbles and not 

to authentioation. 

Claima lJ and 14 have been awmded to substitute "deriving" trm 

Jrl;il11111&11 Tho use to which the out~t eigna.l.s are put would seem to be 

~ no llQ'l'& importance than the manner or us~ the output signals ot a 

new method ot telegraphl'. In the matter or .tunct1onali't7, it is obvious 

tbat Applicant's JDethod could be iraoticed with other machines and bJ' 

band.
