  • Patent number: 5201024
    Abstract: A double loop heat storage space heating furnace has a housing with an upper heat storage section containing an electrically heated heat storage brick portion and a lower section containing an air-to-air heat exchanger having first and second air flow passages. The furnace has two separate flow courses. The first flow course uses a room air fan to circulate room air through the first passages of the heat exchanger. The second flow course has a recirculating fan in the lower housing section for recirculating air in a continuous closed loop through the heat storage brick portion to be heated and the second flow passages of the heat exchanger so that heat is delivered from the heated recirculated air and the room air in the heat exchanger. The upper housing section includes a cooling air space surrounding the heat storage brick portion through which the room air fan circulates a portion of the room air to maintain the furnace housing at a temperature similar to that of the room air.

  • Patent number: 5197112
    Abstract: An electric forced air heating device using PTC elements for heating and having a fixed volume of airflow established by a blower driven at a constant rate. A pair of parallel air paths are established in the device, with one air path having the PTC elements fixedly located therein. A laterally movable damper is used to control airflow through the two air paths, and is positioned proximate the PTC elements a fixed distance therefrom so that as the damper is shifted, airflow proportionally increases through one of the air paths and proportionally decreases through the other air path to control the heat output of the PTC elements. The energization of the PTC elements and blower is controlled by a switch activated by movement of the damper.

  • Patent number: 5173593
    Abstract: A car-borne electric cigar lighter includes a receptacle having a spring contact for receiving the heater element of the lighter for energization. A pair of spaced electrially conductive connecting plates form part of the electrical circuit to the spring contact. A circuit breakable electrically conductive spacer including a heat resistant, form-retaining resilient plate of an electrically insulating rubber, e.g., silicone rubber, penetrated between opposite surfaces with a thermally fusible, electrically conductive portion made from a low melting point metal, e.g., tin foils, to be in contact with the two connecting plates on both sides of the spacer forms an electrical connection between the plates through the tin foils. In case of overheating, the tin foils are melted down to open the electric circuit to the spring contact without losing the mechanical integrity of the spacer to serve as an insulator between the connecting plates.
