U.S. Patent No. 7,681,672 for cryogenic pulsejet and method of use.
A cryogenic system is described for boring a small-diameter hole through various materials including rock, soil and stone. It employs a valveless technique in a borehead [3000] where cryogenic fluid [7] fills at least one pulsejet [3100] which has proximal [3001] and distal [3003] ends. The cryogenic fluid [7] is frozen into a plug [8] near the distal end [3003], acting as a valve. Cryogenic fluid [7] just distal to the frozen plug [8] is rapidly heated by thermal units [3510, 3530] causing it to become a rapidly-expanding gas bubble. The rapidly-expanding gas bubble forces any liquid [7] distal to the expanding gas out of the distal end [3003] of each pulsejet [3100] causing it to impact the material [I]. Rapidly repeating this process causes the system to bore a hole through the material [I].

U.S. Patent No. 7,556,056 for single point battery watering system with pivot float and ball valve.
The present invention relates to single point fluid supply systems for replenishing a liquid electrolyte in a plurality of battery cells simultaneously and in particular to a series of cell fill valves interconnected by a series of hoses and T-connections, one to each cell, each cell fill valve controlled by a ball in a seat in a single fill opening, the ball controlled by a float on a pivotable lever arm with an end finger which holds the ball up to admit water with the float down and allows the ball to lower onto the seat as the cell fills causing the float to rise to a shutoff level when the cell is filled to a desired level.

U.S. Patent No. 7,584,807 for Multiple Pulsejet Boring Device for rapidly boring through the ground having directional boring capabilities.
ABSTRACT:
A method and device for boring a hole through a material along a desired path includes an umbilical subsystem [2000] connected to a boring subsystem [3000] having a plurality of pulsejets [3100]. These pulsejets [3100] repeatedly receive and ignite a combustible fluid [7] in a combustion chamber [3230] causing a portion of the fluid [7] to be forced out of a nozzle [3260] at high speeds as a fluid slug [10] that impacts materials ahead of the pulsejet [3100].
