Abstract: A beam tank includes a tank mounted on two mountings located one towards either end of the tank and with the tank being secured to the mountings by removable securing means so that the tank can be removed from its mountings. Each mounting includes a tank cradle spaced from and connected to an end frame. The tank is rotatably connected to each of its end frames by tank end connections.

Abstract: A glass window for a vehicle, especially an automobile rear window carries a heater extending between a pair of spaced bus bars. The bus bars are connected to terminals on the window which are close together near a periphery of the window, preferably near the lower edge. The leads which connect the terminals to the bus bars are each fixed to a surface of the window and are sufficiently spaced from the window edge to reduce any stray capacitance to a level such that a useable radio signal is supplied to a radio receiver by a decoupling circuit connected between the heater terminals and a power supply.
