Abstract
Abstract A power cord for a television set encompasses the antenna cable in a single, molded unit. An exterior antenna cable terminates in a capacitive coupling unit adjacent to the electrical power wall outlet in the building such that when the power cord is plugged in, the television antenna lead is automatically capacitively coupled to the exterior antenna television cable. Permanent magnet means in the outlet aid in holding the capacitive coupling in place.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A combined power and antenna cord for television sets comprising, in combination: a. power leads for connection to one end of the TV set and terminating at their other ends in plug prongs; b. a signal transmission line including two conductors for connection at one end of the TV set and connecting respectively to a central flat conducting disc and surrounding conducting washer; and c. an insulating plastic material molded about said power leads and transmission line to define a single elongated integral cord, said plastic material defining a plug body for said plug prongs and a downwardly extending flexible flap within which are imbedded said disc and surrounding washer, whereby capacitive coupling of TV signals can be effected to said disc and washer.
Claim 2
Dependent Claim
124 words
A combined power and antenna cord for television sets comprising, in combination: a. power leads for connection to one end of the TV set and terminating at their other ends in plug prongs; b. a signal transmission line including two conductors for connection at one end of the TV set and connecting respectively to a central flat conducting disc and surrounding conducting washer; and c. an insulating plastic material molded about said power leads and transmission line to define a single elongated integral cord, said plastic material defining a plug body for said plug prongs and a downwardly extending flexible flap within which are imbedded said disc and surrounding washer, whereby capacitive coupling of TV signals can be effected to said disc and washer.
Claim 3
Dependent Claim
16 words
The combination of claim 1, in which said two conductors are defined by a coaxial cable.
Claim 4
Dependent Claim
95 words
The subject matter of claim 1, further including, in combination, an electric wall outlet box for receiving said prongs; conductive magnetic means incorporated in said electrical wall outlet box having north and south poles for connection to a master television antenna and coaxially arranged and terminating in flat surfaces positioned and dimensioned to be substantially opposed to and congruent with said disc and surrounding washer in said flap when said prongs are received in said box so that capacitive coupling is retained by magnetic attraction of said disc and surrounding washer to said poles respectively.
Claim 5
Dependent Claim
26 words
The subject matter of claim 3, in which said electrical outlet box includes a removable cover plate, said magnetic means being incorporated in said cover plate.
Claim 6
Dependent Claim
50 words
The subject matter of claim 3, in which a portion of said cord extends away from said plug body and flexible flap at an intermediate point such that pulling on said cord will exert a substantially equal force on said prongs and flap to facilitate separation from said outlet box.
Claim 7
Dependent Claim
82 words
An integral elongated plastic material defining a flexible cord; and a signal transmission line including two conductors imbedded in said cord, said conductors at one end of the cord connecting respectively to a central flat metallic disc and surrounding flat metallic washer, the said one end of the cord completely imbedding said disc and washer whereby signals may be capacitively coupled from said transmission line through said one end of said cord without exposure of any metallic portions of said transmission line.
Claim 8
Dependent Claim
82 words
An integral elongated plastic material defining a flexible cord; and a signal transmission line including two conductors imbedded in said cord, said conductors at one end of the cord connecting respectively to a central flat metallic disc and surrounding flat metallic washer, the said one end of the cord completely imbedding said disc and washer whereby signals may be capacitively coupled from said transmission line through said one end of said cord without exposure of any metallic portions of said transmission line.
Claim 9
Dependent Claim
17 words
The subject matter of claim 6, in which said two conductors are defined by a coaxial cable.
Claim 10
Dependent Claim
33 words
The subject matter of claim 7, further including power leads imbedded in said plastic material whereby said flexible cord may be utilized to transmit both power and signal energy to a television set.
