Abstract: A pipe inspection system and method for accessing and inspecting a feeder tube extending from a larger header pipe at an angle are disclosed. A pipe inspection tool including a head piece and a delivery tube are positioned within the header pipe and aligned with the feeder tube using cameras or other alignment means. The head piece includes a jack that presses the head piece against the interior surface of the header pipe at the feeder tube to create a sufficient seal to deliver a PIG or another pipe inspection device to the feeder tube.

Abstract: A described embodiment provides a technology for concentrating or focusing electromagnetic energy to an arbitrary desired spatial distribution, utilizing a rotatable base, a plurality of mirrors mounted to the rotatable base, and an optical receiver that is moveable in an azimuth path relative to the plurality of mirrors. A described embodiment can comprise a driver for rotating the base and a adjusting linkage that connects the plurality of mirrors so that they track in a coordinated fashion. Another embodiment comprises an optical positioning assembly on which each mirror is mounted. An optical positioning assembly adjusts each mirror to the sun's altitude and the location for the optical receiver. This assembly is connected to the adjusting linkage so that a single driver can move all the mirrors if desired.

Abstract: A gas amount measuring device including a vacuum container, a first pipe, an air release valve being attached to the first pipe, a second pipe, a calibration gas generator being attached to the first pipe, a third pipe, a vacuum gauge, a first valve, a leak valve, a second valve, a turbomolecular pump, a third valve, and a roughing pump being attached to the third pipe in order from a vacuum container side, a first bypass pipe connecting the third pipe between the vacuum container and the first valve to the third pipe between the leak valve and the second valve, a fourth valve being attached to the first bypass pipe, and a second bypass pipe connecting the third pipe between the leak valve and the second valve to the third pipe between the third valve and the roughing pump, a fifth valve being attached to the second bypass pipe.

Abstract: Disclosed is a method of adding silicon to aluminum. The method is characterized in that silicon particles having a diameter ranging between 2 mm and 50 mm are added to a molten aluminum together with a flux represented by the general formula XaMFb, where "X" represents an element included in the third or fourth period of the Periodic Table, "M" is a III or IV group element of the Periodic Table, and "F" is fluorine. A part of the flux may be added in the form of coating on the surface of the silicon particle.

Abstract: Iron rings and radially polarized magnets are alternated with axially magnetized rings on both a rotor and a stator in which like poles of axial magnets on and between the rotor and stator face one another to produce a field within the air gap between the magnets equivalent to that produced by radially magnetized magnets, to redistribute flux within the air gap, to smooth out non-uniformity of individual magnetic flux distributions, to provide repulsion between the stator and the rotor, to minimize energy losses due to rotor rotation, to produce a uniform field in the air gap despite non-uniformity in the magnets, to reduce spin drag torques due to non-uniform magnetization to near zero value, to maximize the flux collection effectiveness of the iron rings, to fill the entire volume with a useful material, and to obtain a more intense field in the air gap, thereby providing a weight effective structure.
