  • Patent number: 4169634
    Abstract: In a system and apparatus for railway car brake control, a brake control apparatus for cars having sprung and unsprung portions is interposed between a train brake valve in a brake pressure supply line and a brake cylinder line of each railway car. A supply chamber is connected to the brake pressure supply line and a control chamber is connected to the brake cylinder line. The chambers are abutted by surfaces of a spring biased diaphragm having different cross-sectional areas. A first valve is responsive to positioning of the diaphragm, which is also selectively fluid biased by a strut cylinder mounted between the sprung and unsprung portions of the railway car, to effect predetermined relationships between pressure drop in the brake pressure supply line and pressure drop in the brake cylinder line. When the particular car is loaded, the brake cylinder line experiences a pressure drop substantially equal to that effected in the brake pressure supply line by the train brake valve.

  • Patent number: 4143923
    Abstract: A brake control apparatus for railway cars having sprung and unsprung portions is interposed between a brake pressure supply line and a brake cylinder line. A first chamber is connected to the brake pressure supply line and a second chamber is connected to the brake cylinder line. The chambers are abutted by surfaces having different cross sectional areas of a diaphragm which is biased. A first valve responsive to positioning of the diaphragm, and a second valve responsive to positioning of a strut in a strut cylinder, effect first and second predetermined relationships between pressure drop in the brake pressure supply line and pressure drop in the brake cylinder line. The strut cylinder, mounted between the sprung and unsprung portions of the railway car, may be adapted to sense partially loaded as well as fully loaded or unloaded conditions.

  • Patent number: 4123115

A first chamber is connected to the brake pressure supply line and a second chamber is connected to the brake cylinder line. The chambers are abutted by surfaces having different cross-sectional areas of a diaphragm which is biased. A first valve is responsive to positioning of the diaphragm, which is fluidly biased by a strut cylinder mounted between sprung and unsprung portions of the railway car, to effect predetermined relationships between pressure drop in the brake pressure supply line and pressure drop in the brake cylinder line. The strut cylinder can be adapted to sense partially loaded as well as fully loaded or empty car conditions.

  • Patent number: 4042501
    Abstract: Iron containing aqueous, acidic solutions, such as acidic stripping solutions used to remove iron from organic extractants, are purified by subjecting the acidic solution to a hydrothermal treatment at elevated temperatures and pressures which cause the precipitation of the dissolved iron in easily separable form. The hydrothermal treatment is accomplished at temperatures in excess of about 100.degree. C. The process can be applied to acidic solutions containing the dissolved iron in the form of ferric sulfate, ferric nitrate or chloride and is particularly adaptable to acidic stripping solutions resulting from the purification of organic extractants employed to extract iron impurities from solutions obtained in the acid leaching of clays, ores and concentrates.

  • Patent number: 3951764
    Abstract: Aluminum-manganese alloys containing up to about 10.0% by weight manganese are made by reacting molten aluminum with a manganese oxide, such as MnO or MnO.sub.2, under a blanket of fluoridic salts, for example cryolite. The alloy can also be prepared by electrolyzing the oxides of aluminum and manganese in a fluoridic bath using aluminum metal as cathode.
