Abstract: An improved portable fueling facility for aircraft or ground vehicles includes at least one storage tank, an outer tank for providing secondary containment about the storage tanks, a number of saddle members for supporting the outer tank on a flat horizontal surface and a pump for dispensing fuel. A deck compartment may be provided beneath the pumps for providing secondary containment about the supply pipes which are used to supply the pumps and the refueling tubes which are used to refuel the storage tanks. The entire facility is portable, so that it may be redeployed at different locations or airports as needed. Fire retardant material may also be provided between the storage tank and the outer tank to prevent flames from reaching the storage tank during an emergency.

Abstract: A multichannel transmitter incorporating a phase-locked loop frequency synthesizer to generate a carrier signal of a selected radio frequency, which carrier is subsequently amplified, modulated, and radiated into space. In order to prevent abnormal radiation which would take place as when the PLL frequency synthesizer is switched from one transmission channel to another, a transmission stopper circuit is connected to the output of the phase comparator or detector of the synthesizer so as to be actuated thereby when the desired phase or frequency lock is not established in the synthesizer. When actuated, the transmission stopper circuit prevents the wave radiation of the transmitter, as by causing nonconduction through a transistor provided therein. The invention is disclosed as adapted for a transceiver.
