Application 07/987,048
temperature sensing switch means with said selectively operable
conducting means for allowing electric power
to be delivered from said electric power source through said
selectively operable conducting means to said electric heating
element responsive to said on-off switch means being on and said
temperature sensing switch means indicating that the ambient
temperature of the outside environment is below a certain
threshold and for disallowing electric power to be delivered from
said electric power source through said selectively operable
conducting means to said electric heating element either
responsive to said
on-off switch means being off or said temperature sensing switch
means indicating that the ambient temperature of the outside
environment is above said threshold, characterized further in
that said selectively operable conducting means is a relay having
a coil and normally open contacts that are operated by said coil,
said means operatively relating said on-off switch means and said
temperature sensing switch means with said selectively operable
conducting means comprises means connecting said coil in series
with said on-off switch means and said temperature sensing switch
means, and said contacts are connected between said electric
power source and said electric heating element.
The examiner relies on the following references:
Marriott 3,982,092 Sep. 21, 1976
Jones 4,277,672 July 07, 1981
Heuser et al. (Heuser) 35 13 157 A1 Oct. 16, 1986

Claims 2-5, 8-11 and 13-15 stand rejected under 35 U.S.C.
§ 112, first paragraph, as being based on an inadequate
disclosure. Claims 2, 5, 9-11 and 13 also stand rejected under
35 U.S.C. § 103. As evidence of obviousness the examiner offers
Marriott in view of Jones or Heuser.
