Abstract: A wall mounted programmable thermostat is provided with a cover plate that normally overlies a portion of a keyboard selector portion and is pivotally mounted so as to open downwardly. The inner cover face has written operating instructions thereon.

Abstract: An improved inside rearview mirror particularly adapted for use with automotive vehicles, the mirror incorporating improved means for detecting and comparing the relative brightness of light forwardly and rearwardly of the vehicle and improved means responding automatically to annoying glare from the rear of the vehicle to move a reflective element from a full reflective mode to a partial reflective mode and also automatically return the reflective element to a full reflective mode after the source of the annoying glare is removed.

Abstract: Apparatus is provided for a wall mounted thermostat to accept and convert manually generated instructions to binary encoded electronic impulses to control ambient air conditions in the environment in which the thermostat is located. The parameters of operation include a building heating control which reduces the desired ambient temperature at night, beginning at a prescribed time and returning to a higher daytime level at a different prescribed time. The system may also adjust desired temperature depending upon humidity conditions and alter the timing of heating and air conditioning control by predicting when a desired temperature will be reached in order to avoid overshoot. The system includes a liquid crystal or light emitting diode display and communicates with a power source and with heating and air conditioning switches such as relays or contactors.

Abstract: An electrical furnace heater construction having electrical heaters carried by a frame and having a current fused drawer-like lead unit movably carried by the frame and having leads for directly and electrically interconnecting to terminals of the heaters when the unit is in one position relative to the frame, the frame having terminals for electrically interconnecting the leads of the unit to power source leads so that the power source leads will be directly and electrically interconnected to the terminals of the heaters by the unit. A temperature responsive power device is carried by the frame and is responsive to the output temperature effect of the electrical heaters, the temperature responsive power device being operatively associated with the unit to move the unit out of the one position thereof to disconnect the leads thereof from the terminals of the heater when the temperature responsive device senses a certain adverse output temperature effect of said electrical heaters.

Abstract: A solid state ignition system particularly adapted for use in igniting fuel oil, the system including plasma generator means, electronic trigger means and electronic brake means and being effective to produce an improved ionization arc between electrodes for the purpose of initiating fuel oil combustion.

Abstract: A solid state oil burner safety control system with integral ignition and particularly adapted for use with a motor powered oil burner, the system providing intermittent ignition, timed safety shutdown, motor starting capability and automatic restart in the event of combustion failure. The system is also adapted to prevent burner motor starting if the line voltage is below a predetermined value.

Abstract: An electrical control housing and support package including a mounting base, a support member floatingly mounted on said base and a cover secured to said base, said package having improved heat sink, heat transfer and heat dissipation qualities, providing improved environmental protection and support for the components of electrical control systems, and also being susceptible of manufacture and assembly with automated techniques.
