  • Patent number: 4104722
    Abstract: This invention provides an improved method and apparatus for celestial navigation. A reference spherical triangle is established from the coordinates of the ground position of an observed selected celestial body and an assumed position for the observer. A second right spherical triangle is then derived from a functional relationship between the first triangle and the observed height of the celestial body. The location of the end of the hypotenuse of the second triangle opposite the ground position defines a point of position on a line of position for the observer. The compass bearing for the line of position is functionally derived from conventional relationships and the line of position may be plotted through the point of position. Plotting means are provided to maintain the spaced relationship between lines of longitude and lines of latitude as a function of latitude for a mercator map projection and to directly plot the point of position on the plotting means.

  • Patent number: 4104420
    Abstract: A large area photovoltaic cell comprising a layer of multicrystalline cadmium sulfide, about 1 to 2 microns thick, formed by simultaneously spraying two suitably selected compounds on a uniformly heated plate of Nesa glass, thereafter forming a coating of Cu.sub.2 S over the cadmium sulfide layer while the latter is heated, to form a photovoltaic heterojunction, applying thereover a layer of CuSO.sub.4, and applying electrodes of Cu and Zn, respectively, to separated areas of the layer of CuSO.sub.4, and heating the cell to form a cuprous oxide rectifying junction under the copper electrode by reaction of the Cu electrode with the CuSO.sub.4, while diffusing the zinc through the body of the cell. The diffusion of the zinc provides a negative electrode coplanar with the positive copper electrode, eliminating any need for introducing mechanically complex provision for making a connection to the Nesa glass, while the use of a CuSO.sub.

  • Patent number: 4085254
    Abstract: In one exemplar embodiment, a biological source of electrical power is provided. The electrical power source comprises a pair of electrodes formed of elements having differing electromotive force. Interposed between the electrodes and in contact with them is an electrolytic material comprising an aqueous brine solution containing coexistent aerobic and anaerobic bacteria derived from a marine organism source mixed with a bacteria nutrient and filler composed of a finely divided cellulose material. All of the aqueous brine solution containing the bacteria is absorbed and carried by the finely divided cellulose material insuring that no free liquid remains. The aqueous brine solution containing the bacteria acts as the electrolyte for the power source and when an external load is applied to the terminals a usable voltage and current are produced.

  • Patent number: 4081992
    Abstract: A reaction tie-down system for axially load testing foundation members is provided by removably interconnecting a plurality of high tensile strength bar members from a base plate within a concrete anchor shaft through an adaptor to load-carrying girders. Hydraulic jacks apply an axial load between the foundation shaft which is to be tested and the girders. The reaction force to this axial load is provided by the reaction tie-down system wherein the force is transmitted from the girder through the rods to the anchor shafts and through the anchor shafts to the surrounding soil. The bar members are arranged in a circular pattern for flexibly matching the number of bar members to the anticipated test load. The bar members threadly mate with the base plate and the adaptor and the bar members are removably encased within the concrete anchor shaft by flexible sheaths. All the components are, therefore, reusable except the embedded base plate assembly and flexible sheaths.

  • Patent number: 4077333
    Abstract: An adjustable table is provided for use with a hospital bed and which allows a person reclining in the bed to easily change the angle of inclination of the table surface. The planar member is rotatably connected at one end to and extended horizontally outward from a vertical support member by means of frictionally engaged gripping elements. Lifting up on the free end of the planar member disengages the gripping elements whereby the planar member can thereafter be freely tilted or rotated about its longitudinal axis to a selected angle of inclination. Lowering the free end of the planar member to its original position re-engages the gripping elements to fix the planar member at the selected angle of inclination.

  • Patent number: 4071278
    Abstract: In a leaching process to recover a selected element or mineral from a gangue, an AC current is applied to the mixture to accelerate the rate at which chemical reactions occur. If the treated material is located in a subsurface earth formation, the AC current may further generate gases in situ to assist in moving and circulating the leaching solution in the formation and to bring the dissolved mineral value to the surface through a borehole or the like. This acceleration of the chemical reactions can shorten the effective leaching time from weeks or months to a matter of hours or days, thereby greatly affecting the rate of recovery of the mineral value and making such leach mining economical on a commercial basis.

  • Patent number: 4068638
    Abstract: Methods and apparatus are provided for increasing the vaporized proportion of a stream of volatile liquid fuel supply to an internal combustion engine. The non-volatilized portions of the fuel discharged from the carburetor are traveled over a plurality of flow surfaces, such as the surfaces of a layer of metal balls and the like, whereby the fuel mixture will not only be more evenly distributed, but whereby the liquid portion therein will also convert to a vapor before entering the intake manifold of the engine. In addition, a coil of tubing is also preferably provided with one end arranged to receive fresh air heated by the exhaust manifold of the engine, and with the other end downwardly directed from the layer of balls to the intake manifold, whereby the hot air will not only heat and further enhance vaporization of any remaining fuel liquids, but will also create a downdraft further redistributing the fuel vapor being supplied to the engine.

  • Patent number: 4037655
    Abstract: In one exemplar embodiment, method and apparatus include providing an electrode disposed in a plurality of vertically spaced boreholes penetrating the formation. The plurality of electrodes in contact with the salt water and oil of the formation are connected to a source of electrical power for establishing an AC electrical field of current flow between the spaced elctrodes. The electrodes are insulated from the earth structure surrounding the borehole for preventing an electrical current path between the electrodes and the earth structure for isolating the electrical current path from the electrode into the formation. The AC electrical current path through the formation generates volumes of free hydrogen in the formation where it is trapped for increasing the formation pressure. The increased pressure of the formation will drive the oil into producing boreholes spaced from the electrode boreholes.
