A geosynchronous Solar Power Satellite System is created by an artificial gravity, closed ecology, multiple use structure in low earth orbit that manufactures modular solar power panels and transmitter arrays. This facility takes empty fuel tanks and expended rocket boosters from launch vehicles that are sent into low earth orbit, and re-manufactures them into structural components. These components are mated to solar cells that are launched from earth. The modular solar panels are transported to geosynchronous orbit by vehicles with ion engines, where the panels are mated to other solar panels to collect power. Structural components are also mated to transmitter elements launched from earth. These are likewise transported to geosynchronous orbit. They are mated to the solar power collecting panels and they beam the collected power back to earth.

The invention relates to a manual ramming assisted gravity type cylindrical sediment collector. The manual ramming assisted gravity type cylindrical sediment collector comprises a blocking mechanism, a counterweight ramming mechanism and a collecting mechanism, the blocking mechanism comprises a sealing plug sleeve, a sealing plug and a pull bar sleeve, the collecting mechanism comprises a collecting tube connected to the bottom of the sealing plug sleeve, the counterweight ramming mechanism comprises a counterweight block movably sleeved outside the pull bar sleeve and positioned between a blocking triggering device and the seal plug sleeve, and the counterweight block comprises a lower portion for ramming the sealing plug sleeve and an upper portion for triggering the blocking device to decrease the seal plug. In the invention, the lower portion of the counterweight block is used to assist the ramming of the sealing plug sleeve to make the collecting tube have an ideal penetration depth in the sediment, so the constant depth collection is realized; the upper portion of the counterweight block is used to trigger the blocking device, and the sealing plug is used to block a channel between a water outlet and the collecting tube, so the manual sealing of the collecting tube is realized, and the falling of the sediment in the rising process of the collecting tube is prevented; and the collector has the advantages of convenient operation, strong operation stability and high collection success rate. The collector can be used for sampling water sediments.

A method of production of a component having at least one dimension that is more than 200 mm, said method comprising the steps of: a) providing a titanium aluminide melt; b) providing a cold sand casting mould; c) mounting the mould and the melt in a vacuum or inert atmosphere chamber; d) rotating the mould at a distance from a rotation axis to generate an artificial gravity in all parts of the mould of at least 30g; e) pouring the melt along said axis of rotation into a gateway that leads the melt to a radius greater than a maximum radius of any part of the mould, the gateway being arranged to open into the mould in a direction contrary to that of said artificial gravity; f) wherein said pouring is at a speed that fills the mould in less than 5 seconds. The method is useful for the casting of long turbine airfoils used in electricity generation industry or large automotive turbocharger wheels.

A microlens is affixed in the far field of an optical fiber to spatially transform a beam either entering or exiting the fiber. In a first embodiment, a droplet of photo polymer is placed on the end of an optical fiber and the fiber is spun to create an artificial gravity. The droplet is cured by UV radiation during the spinning. In a second embodiment, nanoparticles are mixed into the droplet to increase the refractive index of the photo polymer. A third embodiment employs artificial gravity to attach a microsphere to the end of the optical fiber. A fourth embodiment chemically treats the surface of the microsphere so that the requirement of artificial gravity is either reduced or eliminated. In a fifth embodiment the droplet is cured under equlibrium or nonequilibrium conditions to obtain different final shapes for the lenslet. A sixth embodiment discloses fabrication of microlens arrays.
