Abstract: This invention provides a device which facilitates electrical wiring and equipment costs for electricians installing disconnect boxes, typically in the vicinity of an outside air conditioner unit. Thus, an improved disconnect box for protection of an electrician who is servicing an electrical appliance such as an outside air conditioner is provided which incorporates an integrally mounted auxiliary electric socket accessory giving the electrician a source of power for use while the electrician is safely assured that there is no power connected to the electrical appliance being serviced. The auxiliary electrical socket accessory may optionally be connected to a power line source as a full time electric plug outlet or one only accessible when the disconnect box is conditioned to disconnect power from the electrical appliance. Provisions are made for protection of the electrical socket accessory with fusing or circuit breaker protection and ground fault protected electrical input wiring to the electrical socket.

Abstract: A modularized electric box system provides a minimum of modular elements, typically two or three from which a basic anchor box may be formed with protruding members for support by a building body, and from which gangable extensions thereto may be fashioned. The modules may constitute a basic open front electrical box frame having at least one open side with interlocking structure for receiving and supporting either a sidewall panel or a gangable U-shaped extension box module. An anchoring box may be formed with anchoring structure integrally protruding from end panels thereof adapted for attachment to a building body. Thus minimally a basic U-shaped box frame module without sidewalls interlockable with a similar module and a removable sidewall module interlockable upon a U-shaped box frame at the open sidewalls will form a gangable box system. Interlocking channelwork permits unimpeded insertion and removal of modules by sliding movement perpendicular to the open box fronts.

Abstract: This invention relates to a simplified, substantially self contained fuel savings control system for in-room air conditioner/heater units, which automatically turns off the power when the room is unoccupied. The system is typically contained in a single housing unit that may be plugged in between an in-room power line outlet and a power cord to the heater-cooler unit. The system is universal in scope, being adaptable to different kinds of thermostatically controlled systems powered from a local power line. That is achieved, in part, by letting the temperature controls built into in-room thermostatically controlled units establish the temperature and controlling the power to the in-room units by sensing room occupancy and removing power when the room is unoccupied.

Abstract: A form fitting flexible sheet van barrier wall is held in place by reusable adhesive strips as a dust sealing thermal barrier for mounting behind the driver compartment of a van to divide the van into driving and working compartments. The sheet may be rolled up and stored adjacent the van roof. The flexible sheet carries a window which may be opened to permit the flow of air between the compartments. Also weight bearing accessories are provided on the sheet for storing items such as coat hangers and work tools. The barrier comes in an assembly manually retrofittable to vans without tooling or van modification.
