Abstract: Insulation penetrating contact of a single piece electrical blade and contact is achieved in a connector of dead front construction by providing a single piece three link insulating housing adapted to fold up in valise fashion about the single piece blade and contact and about a wire extending into the housing. Electrical contact is made as the housing is closed and fastened in close form by forcing a bladed surface of the electrical contact into a channel in which the wire to be contacted is disposed.

Abstract: A circuit for controlling the brightness of a vacuum fluorescent display having filament terminals and connected to anode or segment biasing means includes a transformer having a filament winding connected to the filament terminals. The transformer is driven by a 60-cycle power source. An electronic switch, including a transistor, is connected between a center tap of the filament and the anode biasing means (at a common ground) and circuit means open and close the switch at a 60-cycle rate. The ratio of time during which the switch is closed to the time during which the switch is open is variable to control the brightness of the display.

Abstract: A room thermostatic control providing for automatic power defer, i.e. modification of load consumption of electrically energized heating and cooling systems during intervals when there is a peak load demand on the electrical supply system. During power defer ambient indoor temperature is controlled by set point adjustment to minimize discomfort, e.g. by pre-boosting, by ramped temperature deferral at controlled rates, and thereafter by ramped recovery at controlled rates to the reference, i.e. desired, temperature. The preferred embodiment has normal and night set back reference temperature potentiometers and ambient indoor temperature sensing circuits providing, respectively, analog reference and analog indoor signals. Digital set point signals are derived and compared with the analog indoor signal to actuate relays controlling operation of the heating and cooling means, e.g. compressor and auxiliary resistance heating. A circuit sensing external conditions, e.g.
