Abstract: A satellite repeater system (10) provides a connection from satellites (12) to user terminals (14) that are located within a building. The satellite cellular repeater system receives satellite signals on a satellite receive antenna (18) and retransmits the received signal within a building using amplifiers (30) and indoor antennas (32). The system also receives signals from a user terminal, amplifies the signals, and retransmits the user terminal signals with an outdoor satellite antenna (20) back to a satellite. For a multi-story building each floor may be provided with a local transmit antenna (32), transmit amplifier (30), receive antenna (34), and receive amplifier (36) for conducting bidirectional communications with satellite telephones or user terminals that are present on that floor.

Abstract: A spring-cushioned coulter running ahead of the applicator for cutting an initial slot in any residue and for providing a break line for the soil to be parted by the trailing shank. The trailing shank, in turn, spreads the initial slot, and deepens it, for the entry of a slurry delivery tube welded behind the shank. At the bottom of the shank is a shoe having a pair of side wings. A downward and outward slope of the wings creates a flat, peaked soil profile ("sole") beneath the wings having sides which slope downwardly and outwardly, conforming to the shape of the wings. The lift surfaces of the wings slightly raise the soil laterally of the shank from the center toward the ends of the wings to provide slots or fissures above the sloped edges of the sole, permitting, and promoting the lateral distribution of the slurry.

Abstract: A unique coulter has a flat band adjacent the peripheral cutting edge to form a slot. Inwardly of this flat band, and on one side of the coulter blade is an inclined compacting surface. The outer, cutting edge of the coulter enters the soil first and as the machine moves forward the compacting surface of the coulter is brought into engagement with one wall of the partially formed slot to firm the soil adjacent the top of the wall. At the rear of the coulter, behind the compacting surface, there is a delivery chute or tube for depositing the fertilizer into the slot formed by the coulter.

Abstract: A device for sealing between and damping of adjacent rotor blade platforms is provided which includes a forward seal member, a compliant center seal member, an aft seal member, a first damper, and a second damper. The first damper is disposed between the forward and compliant center seal members, and the second damper is disposed between the compliant center and aft seal members. The compliant center seal member is disposed between the first and second dampers. The compliant center seal member accommodates misalignment between adjacent rotor blade platforms by deflecting in response to centrifugal forces acting on the dampers.

Abstract: An aerodynamic buffer zone in the gap between the tip of an air cooled axial flow turbine blade of a gas turbine engine and its surrounding shroud or seal (outer air seal) is created by discretely discharging a high velocity stream of cooling air from the tip of the blade in a judicious direction. The stream is angularly oriented relative to the plane of rotation of the turbine so that it is discharged in the gap in the direction of the pressure side of the turbine and preferably at between a 15.degree.-45.degree. angle relative to the flat surface of the tip of the blade.

Abstract: Soil comprising small soil particles, clay and silt particles, humus, fine vegetation, and contaminated with soluble or insoluble radioactive species is treated by first introducing an aqueous extracting solution comprising a mixture of sodium and potassium carbonate (or bicarbonate), or ammonium carbonate (or bicarbonate) into the soil to solubilize and disperse the radioactive species into solution. The extracting solution has a pH greater than or equal to about 7.5. Contaminated fine vegetation then is separated from the soil and extracting solution. Next, an acid like hydrochloric acid is introduced into the soil. The acid is added in an amount sufficient to lower the pH of the extracting solution at which point desirable organic material will substantially precipitate or coagulate from the extracting solution. The cleansed soil particles, including organic matter, is separated from the contaminated extracting solution.

Abstract: An antenna (70) includes a first sub-structure (72) having a major plane that is oriented at a first angle (for example, 90.degree.) with respect to an axis (normal) that is perpendicular to the surface of the earth. The antenna also includes a plurality (for example six) of second sub-structures (74) individual ones of which have a local major plane that is disposed at a second angle (for example, 45.degree.) to the major plane of the first sub-structure. Each of the plurality of sub-structures have an outwardly pointing normal from the local major plane that is oriented at a third angle (for example, 60.degree.) around the axis from an outwardly pointing normal of an adjacent one of the sub-structures. The outwardly pointing normal of each of the plurality of sub-structures is disposed so as to point away from the axis. At least one antenna element (76) is supported by the first sub-structure and by each of the plurality of second sub-structures.

Abstract: A conservation tillage unit for use in primary tillage includes a rolling coulter followed by a chisel plow having a narrow shank and a soil working unit mounted to the bottom of the shank. The working unit includes a point and a delta wing mounted behind and above the point, and forward of the shank. The working unit fractures the soil beneath the surface without throwing the surface soil and residue to the side and while leaving only a narrow furrow behind the shank even at ground speeds up to five to seven miles per hour.

Abstract: A wellbore operation in which a downhole tool is given rotary motion without rotating the tubing string to which it is attached. A "Yankee screwdriver" type of connecting element is used to connect a downhole tool to a tubing string so that compressive forces acting on the connector as a result of relative linear movement between the connector and the tool cause the tool to rotate. A number of various types of downhole operations are possible, such as rotating a tool away from an obstruction and retrieving the upper section of a lost tubing string.

Abstract: A conservation tillage unit includes a coulter and a plow having a shank, a point and a pair of wings mounted slightly forwardly of the shank. The unit fractures the soil at ground speeds up to seven miles per hour without throwing the surface soil and residue to the side and while leaving a reduced furrow behind the shank.

Abstract: An agricultural implement designed for distributing anhydrous ammonia by laterally spaced applicator knives includes an elongated wagon hitch frame which has a forward end pivotally mounted to a forward section of the implement frame and a rear end which carries a drawbar and hitch clevis for a trailing wagon carrying a tank of anhydrous ammonia. As the implement is raised, the rear end of the wagon hitch frame drops away from the implement frame so that the height of the wagon hitch above the ground remains substantially constant and the implement hitch section and wagon tongue remain in line. The break-away coupler for the main hose from the anhydrous tank to the implement is provided with a swing arm to facilitate disconnection of the main hose even when the anhydrous wagon is sharply angled. In the case of a larger implement, having right and left pivoting wings, the frames of the wing sections are strengthened with efficient use of upper and lower laterally spaced channel stiffeners.

Abstract: A method for removing contaminated resin particles from soils. The method entrains the resin particles and fines from the soil, which, due to the difference in specific gravity between resin and soil particles, results in a significant disparity between particle size of the entrained resin and the entrained fines. This, in turn permits the fines to be screened from the resin and the larger soil particles, which have not been entrained, to settle out from the mixture.

Abstract: An electrochemical energy cell for use in a satellite or other environment where failure of the cell can cause great harm or inconvenience is disclosed in which the cell operates within a sealed pressure vessel in which a gas is maintained under high pressure and which is subject to bombardment by meteorites which can cause holes or cracks in the pressure vessel, thereby rendering the cell incapable of conducting an electric current therethrough, which in turn renders a battery of such cells useless. To prevent this, a pressure sensitive switch is provided in each cell which is connected in a circuit which by-passes the current generating discs of the cell when the switch is closed. The switch is normally maintained open by the pressure within the vessel, and is biased to close in the event that the pressure in the vessel drops below a predetermined minimum, so that the damaged cell will still conduct current therethrough to maintain the integrity of the entire battery.
