consideration pursuant to a restriction requirement. 37 CFR §
1.142(b) (1959).
Claim 1 is illustrative of the claims on appeal and is
reproduced below:
1. A method for making high frequency cable of
at least two electrical conductors with each
conductor insulated by thermoplastic material which
concentrically surrounds each respective conductor
comprising:
(a) providing a first uninsulated electrical
conductor;
(b) providing a second uninsulated electrical
conductor;
(c) moving both conductors into an extruder
means which coats each conductor separately and
independently with a heated thermoplastic electrical
insulation material, the extruder means maintains
the concentricity of each conductor with respect to
the surrounding thermoplastic insulation and in a
spaced relationship from the adjacent insulated
conductor;
(d) moving the conductors which have been coated
with heated thermoplastic material from the extruder
means and in a spaced relationship so a[s] to permit
the thermoplastic material on each conductor to set
independent and separate of the other conductor; and
(e) bringing the conductors into touching
contact after the thermoplastic material has set
while using only residual heat from the extruding
means, whereby the coated conductors are fused and
joined together by the heated thermoplastic
materials surrounding each conductor, the set is
achieved whenever the thermoplastic retains its
concentricity upon contact with adjacent
