REUARKS .. 

As regards the use of th~ wori "indepe-ndentl.T' in· ,certain 

ot the claims, while it is true that'·the relatively rotatable contact 

drjmi. and contaot arm depend tor movement upon the same motor• these 

bodies, are~ dependent upon the motor alone tor relative rate ot 

movement •. The rate ot variation is dependent upon the friction drives, 

the cams am the diff'erential gearing, whether functioning separately 

or altogether in combination. Thus, in th~ cambina:tion ot c~:lm 6, tor 

example, it is correct to say that each or the trictipn drives actuates 

said bodies in a discrete- or separate time relation, This claim and 

other claims ot the group criticized have been amended to express the intamed meaning more exactly. 

Claims 7 and 8 have been amended in the last line to meet 

the objection properly noted by the Examiner, which also cures the same 

objection with respect to claim 9. 

Referring to claim 15, the amemmant directed in lim 4 

will overcame the objection on the ground ot indetiniteueH. In this 

claim the same line has also been amended to include structure to 

.Support tne tunotioml ata.t-.ent.

I~ is oontended that·a rand.am. operation oharaoterizes the 

present,innntion, but' a ralld.am operation in respeot to tiiqe, rather 

than a r.andam sequenoe or ordel'le i'h.e group of olaima Ros'. 10, 12, 

13, 14, and 16 rejected as imcdurate ~ this ground have been amended 

and aa now presented are thought to clear. up the point of objection. 

/J,a pointed -out in previous arguments, in a system of campla operations 

' 

as here' disolosed in..whioh oonstants and variabl~s are cCIJlbined, 1=be 

resultant must be variable and unpredictable. 

The. newly oited P,Ltent 'to Boardman·has been considered. . . Boardman shows a f.riction di"ive used in conjU!lQtionwith a awitcbi~ 

devioe ror the sole purpose of permitting manual adjustment by .means 

. ' 

ot a knurled mt {page 2, column 1, line 28 ot Boardman patent)• Be . . 

does not prmride •.means, tor continuously and irregularly varying the 

relation between the elements of the.triotion drive camponents ot his 

invention. 

Furthermore, 'Boardman, i.'l his o.onstruotion shQl'IB a t~iotion 

drive, ma.nually adjustable, tor the se~eotion ot a give.Ji DUmber or 

circuits (as shown in Figs. 9 and 10 ot Boardman) out ot a plurality 

, of oirouits. Be doeJI not shaw at aey place a conatrua;tion permitting . the variation ot the tim8 intar11B.l be~en aucessive circuit~ ot a 

plurality ot circuits. 

-Favorable reoonsideration is oourteously solicited in.the 

' light ot the foregoing. 

Respeattuily submitted,
