Abstract
Abstract A bacteria destroying apparatus for use with a voice communication system such as a telephone system, and telephone systems which have such bacteria destroying apparatus included therewith. The bacteria destroying apparatus may adopt the form of a relatively thin, flat disc which is located in the mouthpiece of a telephone handset, and preferably in close proximity to the diaphram of the handset or any other portion of the voice communication system which normally collects a substantial amount of bacteria thereon as, for example, a result of close proximity of a user's mouth. The bacteria destroying apparatus generates radiation in a wave length range which is effective to destroy bacteria. In one embodiment, the radiation is generated when the element itself is electrically energized. The apparatus also includes an electrically conductive member such as a cable which extends through a portion of the voice communication system, and preferably the telephone handset, for connection to the radiation generating element as well as to a source of electrical power. Thus, when energized, radiation will be effective to destroy any bacteria on the mouthpiece of the telephone handset or other area which is contacted by the radiation. A switch system is provided for effectively disconnecting the radiation generating element from the source of electrical power when the telephone handset is in use.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
240 words
An improved telephone system having a handset with a bacteria destroying means associated with the mouthpiece of said handset, said telephone system comprising: (a) a telephone base; (b) a handset operatively connected to said base; (c) a mouthpiece on said handset having an outer casing, said outer casing having a perforated wall permitting passage of sound waves; (d) a diaphram located within said handset and located in proximity to said perforated wall of said casing; (e) a thin flat radiation generating disc located between said diaphram and the perforated wall on the outer casing of said handset, said disc having means capable of generating radiation in a wave length range which is effective to destroy said bacteria when energized and which radiation will contact said mouthpiece and the perforated wall of said casing, said disc also having a plurality of apertures therein permitting passage of sound waves therethrough to contact said diaphram; (f) a conductive ring section mounted on said disc; (g) electrically conductive means operatively connected to said conductive ring section on said disc through said handset to cause energization of the means generating radiation and thereby causing generation of the radiation to be incident on the perforated wall of said casing; and (h) a reflecting foil on the side of said disc closest to said diaphram reflecting the generated radiation toward said perforated wall and which reflecting foil still permits passage of sound wave to contact said diaphram.
Claim 2
Dependent Claim
240 words
An improved telephone system having a handset with a bacteria destroying means associated with the mouthpiece of said handset, said telephone system comprising: (a) a telephone base; (b) a handset operatively connected to said base; (c) a mouthpiece on said handset having an outer casing, said outer casing having a perforated wall permitting passage of sound waves; (d) a diaphram located within said handset and located in proximity to said perforated wall of said casing; (e) a thin flat radiation generating disc located between said diaphram and the perforated wall on the outer casing of said handset, said disc having means capable of generating radiation in a wave length range which is effective to destroy said bacteria when energized and which radiation will contact said mouthpiece and the perforated wall of said casing, said disc also having a plurality of apertures therein permitting passage of sound waves therethrough to contact said diaphram; (f) a conductive ring section mounted on said disc; (g) electrically conductive means operatively connected to said conductive ring section on said disc through said handset to cause energization of the means generating radiation and thereby causing generation of the radiation to be incident on the perforated wall of said casing; and (h) a reflecting foil on the side of said disc closest to said diaphram reflecting the generated radiation toward said perforated wall and which reflecting foil still permits passage of sound wave to contact said diaphram.
Claim 3
Dependent Claim
64 words
The improved telephone system of claim 1 further characterized in that a coiled wire connects said handset to said base and said coiled wire has a plurality of spaced convolutions therein, said means to cause energization comprises an electrically conductive wire which extends from said handset through the convolutions in said coiled wire to said telephone base and to a source of electrical power.
Claim 4
Dependent Claim
59 words
The improved telephone system of claim 2 further characterized in that said electrically conductive means extends through a portion of said handset and being operatively connected to said radiation generating disc, said conductive means being adapted for ultimate connection to a source of electrical power to enable energization of said radiation generating element and ultimate generation of the radiation.
Claim 5
Dependent Claim
19 words
The improved telephone system of claim 3 further characterized in that said element is constructed to generate ultraviolet radiation.
Claim 6
Dependent Claim
27 words
The improved telephone system of claim 4 further characterized in that said radiation generating element comprises a coating of radioactive tritium on said relatively thin flat disc.
Claim 7
Dependent Claim
41 words
The improved telephone system of claim 4 further characterized in that said electrically conductive means comprises an electrical conductor connected to said disc which extends outwardly of said system for connection to a source of electrical power independent of said system.
Claim 8
Dependent Claim
37 words
The improved telephone system of claim 3 further characterized in that said system comprises switch means operatively connected to said electrically conductive means to enable deenergization of said radiation generating element when said telephone system is used.
Claim 9
Dependent Claim
49 words
The improved telephone system of claim 7 further characterized in that said switch means is located under the handset of a telephone instrument and permits energization of said radiation generating means when said handset is on a cradle, and stops energization when said handset is removed from the cradle.
