摘要： A deep-water power generation system includes an initially evacuated sphere having walls of suitable strength or reinforcement for maintaining its structural integrity in deep-water pressures; a power axle extending from a north pole thereof to below a south pole of the sphere; blades of a turbine secured upon a support frame secured to the axle in a latitudinal plane of the sphere; and inlet ports positioned at the plane of the blades of the turbine and receiving an inflow of ambient deep water against the blade. The fluid flow induces rotation of the blades power axle secured to the frame. A thrust deck is rigidly secured, within the sphere, to the power axle and above the turbine and a generator is secured upon the thrust deck at the south pole of the sphere spirally expelling water from the south pole of the system.

摘要： A construction system for joist girders, includes a pair of opposing bi-planar sheets of structural material, each bi-planar sheet having two alternating series of vertical segments, each segment of the series, in horizontal cross-section, defining a planar base parallel to a base of a successive vertical segment of the alternating series of vertical segments, the bases of each segment of the series integrally connected to each other by sidewalls. Respectively upper and lower horizontal track members define in transverse cross-section, a substantially U-shaped geometry, each track member open-ended for horizontally enclosing and securing an upper edge of each bi-planar sheet of the pair of bi-planar sheets. Several vertical tubular members define, in transverse cross-section, a geometry of a rectangle, said tubular members disposed between the pair of bi-planar sheets and nested within corrugated thereof. Tubular horizontal members each having a partially cut-out lower surface are proportioned for engagement about respective edge areas of the bi-planar sheets.

摘要： A deep-water power generation system includes an initially evacuated enclosure having walls of suitable strength or reinforcement for maintaining its structural integrity thereof in deep-water pressures; a power axle extending through the enclosure from a north pole to below a south pole of the enclosure; preferably concave blades of a turbine secured upon a support frame secured to the power axle in a latitudinal plane of the enclosure; and inlet ports within the enclosure positioned at the latitudinal plane of the blades of the turbine and receiving an inflow of ambient deep water against the blades, in which a couple effect of force from the fluid flow induces rotation of the blades and of the power axle secured to the frame. A thrust deck is rigidly secured, within the enclosure, to the power axle above the turbine and to a generator secured upon the thrust deck. At the south pole of the enclosure, water is expelled into a high-pressure injection well descending to a geological level of a saline aquifer or discharged from a water chamber at the south pole and into a main water body under pressure provided to a discharge chamber in excess of the ambient deep-water pressure.

摘要： A system for guiding of the visually handicapped includes a continuous electrical conductor, in the nature of a wire or strip, having a substantially uniform conductivity embedded within a walkway to be traversed by the handicapped person. The system also including a proximity for detecting the conductor in which the detector may be in a shoe of the user or a tip of a walking cane. The system further includes a signalling element, in the nature of a vibrator, in electrical communication with the detector such that, through the presence of such vibration, the visually handicapped person is able to determine his proximity to the electrical conductor to determine that he is proceeding in a proper direction within or along the walkway. The signalling element is preferably provided with a switch, for example, a mercury switch, so that the shoe or cane circuit will become energized only upon the occurrence of movement or motion of the shoe or cane within which the proximity detector is located. The approach by a user to a location of interest along the walkway, such as an intersection, bathroom, or Braille telephone, may be indicated through the provision of a pattern of irregularity of the conductivity within the continuous electrical conductor. Different patterns of irregularity may indicate different advisories to the user.
