Abstract: Non-random windings are employed to reduce the proximity effect in electrical machines, including rotating machines such as various types of motors. Thus, with respect to electrical machinery of the type wherein multi-strand electrical wiring is received within a slot relative to a surface associated with the transmission of magnetic flux, a method of dressing the wiring within the slot according to the invention includes the step of winding the strands of each turn in one or more layers, each layer being substantially parallel to the surface associated with the transmission of magnetic flux. The winding may be a multi layer winding, in which case the windings associated with each layer are preferably separated by an insulating layer. The invention is applicable to various types of machines and motors, including AC, brushless DC and variable reluctance (VR) types. The conductors may be of a circular cross section or other geometry, such as flattened tapes.

Abstract: A phosphate bath control system and method is provided that tracks the set points of one or more of the major process variables of the phosphate bath independently of variations in the production conditions. A detector determines the current values of Zinc, Manganese and Total Acid provides data to a controller which exponentially filters the data and processes the filtered data in accordance with fuzzy logic rules. The controller periodically updates the flow rate of one or more pumps that control the flow of liquid concentrates to the bath in order to maintain a desired concentration of the various constituents of the bath. Control of an accelerator is provided by incorporating in the controller an additional algorithm for indirect estimation of the accelerator concentration based on a math model which represents the material balance of the accelerator in the bath.

Abstract: An improvement has been found in the gas recovery section of a delayed coking process. In the improvement the compressor discharge is amine scrubbed to remove hydrogen sulfide. The compressor discharge is the entire vapor feed to the gas recovery section and contains about 90% of the hydrogen sulfide. This has been found to cause a significant drop in both the depropanizer and debutanizer pressure and allow a saving in the investment cost of the pressure vessel. Synergistically a reduced amount of hydrogen sulfide is present in the entire gas recovery section. The remaining 10% of the hydrogen sulfide is removed by amine scrubbing the fuel gas and propane/propylene fractions.

Abstract: Superconducting compositions of the general formula A.sub.n Q.sub.m Cu.sub.3 O.sub.y are prepared by wet mixing a combination organic acid salts, inorganic acid salts and oxides of A, Q and Cu, wherein at least one salt is an organic acid salt, drying the mixed salts, and then heating the resultant mixed salts to a temperature between 500.degree. and 950.degree. C. The temperature is maintained for a time sufficient to form a substantially orthorhombic superconducting composition. The method achieves good results with only one heating step. The presence of at least one organic salt causes carbonate and nitrate salts of A, Q and Cu to convert to oxides at temperatures between 300.degree. and 400.degree. C. With lower processing temperatures, semiconductor materials and superconducting materials can be processed together.

Abstract: A color image display system includes a shadow mask type cathode-ray tube having a longitudinal axis, the tube including a panel, a funnel and a neck with a deflection yoke assembly encircling adjoining segments of the neck and funnel. A plurality of neck components are disposed around the neck of the tube. In one embodiment, an external magnetic shield is disposed along opposite sides of the funnel and neck of the tube. The shield extends across the longitudinal axis behind the neck for shunting magnetic fields from the tube while providing access to the deflection yoke assembly and the neck components. In a second embodiment, a second external magnetic shield is disposed orthogonal to the aforementioned external shield and spaced therefrom.

Abstract: Apparatus and method relating to the monitoring of a gas supply to determine the level of certain gas constituents in the supply. There is disclosed a method of monitoring air to determine the hydrocarbon content thereof exclusive of methane. Air is fed through a cold trap maintained at a temperature which produces condensation of the higher hydrocarbons normally found in ambient air at an urban location. Methane, however, passes through the trap. From the cold trap the air is directed to an analyzer, which continuously analyzes the air for hydrocarbon content. Air having all original hydrocarbons is fed the analyzer during intervals interspersed with intervals when the air fed the analyzer has had higher hydrocarbons removed. By comparing the hydrocarbon content of the two types of air, one is enabled to determine the content in such air of hydrocarbons exclusive of methane.
