glass cloth coated with silicone rubber 20 (Figures 1-3;
column 2, lines 27-39; column 3, line 17 to column 4, line 18);
lacing or winding resistance wire 13 through drilled
openings 16 in the base member 12 (column 3, lines 9-12);
joining the base member or card 12 and the two outer
sheaths (column 3, line 17 to column 4, line 18); and
securing the deicer to a surface of an airplane (column 1,
lines 36-39). According to Pfenninger (column 1, lines 9-29;
column 3, lines 27-31; column 3, lines 51-73), the outer sheaths
as well as the base member 12 are electrically and thermally
insulating.
Like Pfenninger, Bloomer describes electric heating pads.
(Page 1, lines 10-16.) In particular, Bloomer describes a
method for making a heating pad in which the metallic conductor
strand is stitched to a flexible, non-conductive body sheet.
(Page 1, lines 10-32.) According to Bloomer (page 1, lines 32-
37 and 90-107), the stitching method allows the conductor to be
attached to the body quickly “with a maximum amount of surface
or length of conductor in proportion to a minimum space.” (Page
1, lines 32-37.) In particular, Bloomer teaches the following
desirable benefits:
[B]y employing the strand as a sewing element, it is
obvious that the pad can be cheaply manufactured with
great speed and when completed, its utility and
