Abstract: A power generation system having a low pressure source of water, means connected to the source of water for pressurizing the water to a substantially higher pressure, means for forming steam from the pressurized water, and a steam turbine for deriving mechanical motion from the steam. The pressurizing means uses first and second chambers of variable volumes. Valve means are associated with the first and second chambers so that water flows into the first chamber when its volume is expanding but water is not allowed to flow into the first chamber when its volume is contracting. Likewise, the valve means are utilized so that water flows into the second chamber when its volume is expanding but water is not allowed to flow into the second chamber when its volume is contracting. Furthermore, valve means are associated with the first chamber to allow pressurized water to flow out of the first chamber when its volume is contracting.

Abstract: A drive-in, single-stop shopping facility for simultaneously vending numerous retail products and fuel to a customer positioned at a fixed purchase station, e.g. a stationary automobile. A method for simultaneously vending retail products and fuel to such a customer. A kit for converting existing gas station buildings into drive-in, single stop shopping facilities of the type described.

Abstract: An improved welding electrode for producing weld metal having low amounts of hydrogen therein so that hydrogen-assisted cracking in the weld zone is minimized. This is especially beneficial for welding high strength steels having tensile strengths of about 70,000 psi and above. The electrode has a filler wire core and a flux covering of predetermined constituents and low moisture levels such as below about 0.6 percent. The flux is bound together with a binder of hydrolyzed organic silicate (silica) which makes no substantial contribution to the moisture level of the covering and which also makes the covering resistant to hygroscopic moisture pickup before the electrode is used for welding. Thus, this binder minimizes the amount of hydrogen from any moisture in the covering which may be introduced into the weld metal during welding. Additionally, the flux covering contains a source of barium or cesium in an amount effective to reduce the slag/metal reaction temperature during welding.

Abstract: A liquid level measuring device having an elongated frame is disclosed. One or more floats are mounted in the frame on cables mounted between pulleys at each end of the frame. Brake pins frictionally engage the guide cables and means are provided to selectively disengage the brake pins from the guide cables. A thermometer may be attached to the frame to provide temperature readings. Also, a timing device may be attached to the frame to provide the proper duration for obtaining exact temperature and liquid level(s) measurements.

Abstract: A CB radio accessory unit combining a plurality of selectively switched measuring means, means for switching multiple antennas, and antenna tuning means is disclosed. The accessory unit permits an operator to quickly optimize CB RF system performance in a given setting and to make performance measurements on the RF system.
