Abstract: The gas-insulated cable (1) has a cylindrically symmetrically   constructed,   high-voltage   electrical conductor  (4),  a  pressure  tube  (3)   filled  with insulating gas,  and a supporting insulator  (2) which holds  the electrical conductor  (4)  centrally in the pressure  tube  (3).  The  supporting  insulator  (2)  is formed by at least one insulating conduit (5'') which is axially guided or wound in the shape of a helix and which rests on the inner surface of the pressure tube (3) with a part of its lateral surface, and rests on the  lateral  surface of the electrical conductor  (4) with another part of its lateral surface.        Such a gas-insulated cable is easy to produce and, in the region of the triple point, has relatively low  peaks  of  the  electric  field  prevailing  during operation of the gas-insulated cable (1).

Abstract: Disclosed is a two-stage high pressure high recovery process utilizing two reverse osmosis membrane systems intended to provide very high overall water recoveries from contaminated inorganic scale-containing water in an economical manner while preventing scale formation on the membrane and prolonging the useful life of themembrane. The first stage of the process involves using a low pressure membrane system to preconcentrate scale compounds while purifying the bulk volume of the scale-containing water (using antiscalants with pH control) and combining the influent water with a recycle stream of concentrate from the second stage membrane process in order to prevent scale formation. This first stage membrane system is followed by a second stage membrane system wherein the concentrate from the first stage membrane system is treated further at higher pressure in order to provide purification of the remaining preconcentrated stream and achieve very high overall water recoveries. Scale formation in the first stage and second stage membrane systems is prevented by the recycle of "softened" water containing a very low concentration of scale-forming compounds and containing a high concentration of soluble salts to both stages in a specific proportion that represents an economically viable process, while ensuring adequate permeatequality. The second stage membrane concentrate stream is "softened" whereby hardness compounds such as calcium, magnesium, carbonate, sulphate, silica and other sparingly soluble compounds are removed by suitable means before it is recycled to the twomembrane purifying stages.

Title: Apparatus and method for providing ignition to a turbine engine
Inventor: FRUS JOHN
IPC: F02P15/00
Filed: 1989-11-02
Abstract: A unipolar ignition of the invention provides a current waveform at the ignitor plug which initially rises relatively slowly, followed by a transition to a fast rising current which quickly peaks and thereafter slowly dissipates.  Such a current waveform provides an initially hotter and longer lasting spark which does not harm the ignitor plug of the system or shorten its life expectancy.  Neither does the spark create stress on the solid state circuitry which delivers the energy to the ignitor plug.  To provide the foregoing spark and current characteristics, an inductor having a saturable core is in series with the ignitor plug, and it provides an initially high inductance which limits the rate of current rise at the plug as energy is transferred from an energy storage device to the plug.  As the current through the inductor increases, its core begins to saturate and the effective inductance begins to decrease, allowing the current to rise more quickly.  As energy is transferred to the ignitor plug, the increasing saturation, decreasing inductance and increasing current complement one another, causing the rate of current rise to increase quickly to a high value desirable for ignition.  Related features of the invention provide for easy diagnostics of the spark and for timing an ignition sequence and providing a repetition rate which aids in a successful ignition.
