Abstract: An electric heating attachment for electrically heating the exterior portion of a sewer vent of a building to keep the vent from clogging from snow and/or ice and frost that may accumulate on the building roof. The attachment has an elongated rod insertable into the vent a with an electric heating tape extending along the length thereof. Laterally extending arms on an upper portion of the rod engage the top edge of the vent to limit the extent of the insertion of the rod into the vent. The section of the rod extending above the lateral arms terminates in a hoop portion having a portion of the heating tape extending therealong to heat the area immediately above the sewer vent to keep this area open to the atmosphere by melting the snow and/or ice above the vent.

Abstract: The invention describes a system for removing the odors associated with the bodily discharge of odorous volatile gases associated with the use by the human body of the toilet stool. A hollow toilet seat having radial holes associated with the centermost portion is supported and communicates with a vacuum device for drawing air from the hollow portion through the radial holes through the ported toilet seat and through this vacuum device. An incinerating device such as a grid of tungsten wires or a glow plug is inserted in the passageway and connected to an electrical source, preferably one of low voltage, for incinerating and burning the odorous volatile body gases. The discharged by-products of combustion may either be discharged into the room or may be discharged through suitable wall fittings to the outside atmosphere. Incinerating the odorous volatile body gases destroys the odor allowing the by-products of combustion to be discharged back into the same bathroom atmosphere.
