Abstract: A fuel system is described for homogenizing a liquid fuel component and a fresh water component by an adjustable emulsifying orifice. The downstream pressure of the homogenized fuel and water components at the suction side of a feed pump is monitored and controlled by a compensating valve which continuously and automatically adjusts the orifice size within the adjustable emulsifying orifice. The compensating valve is arranged in fluid communication with the suction side of the pump to be operative in response to changes in the pressure. The compensating valve is of the diaphragm type having an underlying piston provided with piston rings which prevent fluid communication between the suction side of the pump and its internal connecting assembly in the event of rupture of the diaphragm.

Abstract: A rip-rap laying machine designed to lay approximately 270 tons of rip-rap per hour resembles a huge steel bridge frame. The self-propelled unit overlies an acutely angled bank of a waterway, channel, or canal and moves along the bank (40) to lay rip-rap uniformly. The machine uses two cable-controlled hoppers (34 and 36) mounted on rails (20 and 22). An operator rides with the feeder hopper (36) and controls a loading hopper (34) to run between a dump hopper (32) on one end of the bridge and the feeder hopper (36). The loading hopper (34) transfers rip-rap from a dump hopper (32) to the feeder hopper (36). The rip-rap is transferred from the feeder hopper (36) to a vibratory feeder (38), which vibrates the rip-rap onto deflector plate (44) before rolling gently onto sheets of filter cloth placed upon the bank (40). Uniform placement of the rip-rap on the bank (40) occurs as the vibratory feeder (38) travels from the bottom to the top of the bridge.
