Abstract: A system for detecting a location of a subsurface water channel includes an anchor electrode for disposal in a first body of water and a mobile electrode for disposal in a second body of water. An electric current source can be coupled to at least one of the mobile electrode and the anchor electrode to generate an electric current between the mobile electrode to the anchor electrode. A lead line can be coupled to the mobile electrode to enable the mobile electrode to move a distance in the second body of water. An ammeter can be coupled to the anchor electrode to measure the electric current from the mobile electrode. A processor can compare the current with the length of the lead line to determine the location of the subsurface water channel.

Abstract: Portable cooking apparatus which comprises a support stand for supporting the apparatus above a cooking fire; a pair of flat cooking grills between which food to be cooked may be placed and suspension members connecting the pair of cooking grills to the support stand. The suspension members are manipulatable for moving the pair of grills from a horizontal position to a vertical position and then to another horizontal position as the relative position as one grill on top of the other is reversed.

Abstract: Service station for dispensing fuel to vehicles from fuel dispensers connected by fluid conduits to one or more fuel storage tanks characterized in that the fuel storage tanks are self-contained, flexible and collapsible bladder type tanks supported in an elevated position above the fuel dispensers and the vehicles to which fuel is to be dispensed. An open top containment vessel may also be supported at an elevated position and into which the bladder type tanks may be preferably lowered for non-attached disposition therein.
