Position Sensing for Rotor in Hybrid Stepper Motor

A method and system are provided for sensing the position of a rotor in a hybrid stepper motor. First and second Hall sensors are positioned in a spaced-apart relationship with the first and second armatures of the rotor such that the first and second Hall sensors generate electrical outputs that are 90.degree. out of phase with one another as the rotor rotates. The electrical outputs are adjusted relative to a reference, and the amplitude of the electrical outputs is further adjusted to account for spacing differences between the rotor and each of the first and second Hall sensors

Miniature housing with standard addressable interface for smart sensors and drive electronics

A miniature assembly is disclosed which includes a housing assembly with a cover configured to be sealably secured to a box-like receptacle. The receptacle comprises openings on opposing sides for the seating therein of communications connectors. Enclosed within housing is custom-sized circuit board for supporting, at least, a standard communications interface and at least one electronic device

Soybean Shipping Patterns in the United States for 1985

Information about soybean shipping patterns that enables the soybean industry participants to improve market performance through better decision making will contribute to a more efficient flow of soybeans. Such information may improve the investment decisions in port facilities, rail, truck and barge services, elevator and processor facilities, and farm production. The objectives of this paper are to determine regional soybean flows by mode of transportation for 1985 and compare these flows with similar data for 1977. Soybean flow data were collected for the 1985 calendar year through personal interviews, mail surveys and telephone calls with representatives of the soybean handling, storage and processing firms in 36 states. The volume of soybean exports for 1985 is slightly less than for 1977, and the distribution of these exports by region reveals significant changes. The Gulf exports more than any other region and has become relatively more important from 1977 to 1985. Soybean exports from the Great Lakes have declined significantly and the Atlantic region exports have declined slightly in this period. The biggest relative increase in soybean exports occurred in the Pacific region. Changes in international markets, unit train shipment rates and increased size of ocean shipping vessels are the major factors explaining the changes in export shares among regions. This trend may continue into the 1990s affecting production, transportation and shipping patterns by export ports. Barge shipments continue to be the dominant mode of transportation for export soybeans, accounting for 73 percent of all movements in 1985 compared to 61 percent in 1977. Truck and rail shipments declined from 16 to 8 percent and 23 to 19 percent, respectively, in this same period. Transportation deregulation does not appear to have helped the railroad compete for export bound soybeans. Strong competition among modes of transportation due to excess capacity in rail and barge transportation facilities in 1985 may explain this failure of railroads to gain market share relative to barge shipments. The elimination of the excess capacity since 1985 may change the rail-barge competitive structure during the 1990s

A Multi-Sectoral Analysis of Feed Grain Exports in the Cornbelt Economy

Exact date of working paper unknown.Large feed grain export variations adversely impact the agricultural sector and the Cornbelt economy. A multi-sectoral input-output linear programming model is developed to measure the cross industry effects of a ten percent· increase in feed grain exports. Base model, elastic labor supply, and full employment labor supply results are presented

System providing limit switch function with simultaneous absolute position output

A limit and position sensing system includes a sensor assembly and an emitter. The sensor assembly includes first and second electrical conductors arranged in opposing parallel planes. The first electrical conductor is coiled outwardly from either end thereof in a clockwise fashion to form a first coil region and a second coil region. The second electrical conductor forms a single coil with portions of the single coil's rings lying between the first end and second end of the first electrical conductor being parallel to an axis of the first electrical conductor's plane. Ferromagnetic material is aligned with the first and second electrical conductors and spans beyond (a) the first and second ends of the first electrical conductor, and (b) the portions of the rings of the second electrical conductor's single coil that lie between the first end and second end of the first electrical conductor. The emitter is spaced apart from the sensor assembly and transmits a periodic electromagnetic wave towards the sensor assembly

The Composition of Inorganic Colloids Extracted from Three Iowa Soils

The purpose of this work was to determine the colloidal content of certain soils and to make analyses of the inorganic colloids extracted from these soils. These soils ranging from a pH of 5.53 to a pH of 7.60 were obtained and the total colloidal content determined. The inorganic colloids were then extracted according to Truog and Drosdorff\u27s procedure (2) and analyzed for total SiO2 , Al2O3 , Fe2O3 , TiO2 , P2O5 and available K2O. The total SiO2, Fe2O3, Al2O3 and TiO2 were determined by Hillebrand\u27s method (1). The phosphorus content was determined by the magnesium nitrate method. The available K2O was determined by the Aspergillus niger method
