Abstract: ABSTRACT OF THE DISCLOSURE    With contactor bodies formed of spirally wound corrugated panels providing ducts defined by the corrugation profiles which are alternately filled with waste water and air, there is a problem in completely filling the ducts and in providing a continuous flow through the ducts in a body of simple and rigid construction.  In order to solve this problem, the corrugation profiles of at least one corrugated panel are inclined at a predetermined angle relative to the axis of the contactor body.  In this manner, the disadvantages of the known, mechanically unstable constructions comprising a tube bundle are avoided and an intensive flow of waste water and air within the ducts is achieved.  Advantageously. the corrugation profiles of winding layers arranged radially above each other or axially beneath each other comprise different inclination angles, expecially angles which are opposite to each other.

Abstract: LINEAR POLYETHYLENE SHRINK FILMS                 ABSTRACT OF THE INVENTION           A multi-layered  thermoplastic film having improved physical characteristics is formulated through utilization of a linear low density polyethylene or linear medium density polyethylene resin as a core and/or an intermediate layer constituent.                           FIELD OF THE INVENTION         This invention relates to heat shrinkable, thermoplastic pack-aging films. In particular, the present invention is directed to shrink films utilizing linear low density polyethylene or linear medium density polyethylene resins as a constituent of a core and/or an intermediate layer in a multi-layer film.         BACKGROUND OF THE INVENTION The present invention is directed to new and useful heat shrink-able film formulations.  One distinguishing feature of a shrink film is the film's ability, upon exposure to a certain temperature, to shrink or, if restrained from shrinking, to generate shrink tension within the film.        The manufacture of shrink films, as is well known in the art, may be  generally accomplished by extrusion of the resinous materials which have been heated to their flow or melting point from an extrusion die in tubular or planar form.  After a post extrusion quenching to cool, the extrudate is then reheated to its orientation temperature range.  The orientation  temperature  range  for  a given  film will  vary with  the different resinous polymers and blends thereof which comprise the film. However, the orientation temperature range may generally be stated to be above room temperature and below the melting point of the film.

Abstract: HIGH VOLTAGE METAL OXIDE SEMICONDUCTOR TRANSISTORS          Abstract of the Disclosure A high voltage metal-oxide-semiconductor (MOS) transistor has a source, a drain, a channel extending between the source and drain, an oxide layer overlying the channel, a gate electrode overlying the oxide, and a drift region surrounding the drain.  Adjacent the source, the oxide layer is thin and adjacent the drain it is thick.  Between the thin and thick oxide regions, at a location overlying part of the drift region, the oxide is of intermediate thickness.  In operation the voltage applied to the drain is distributed along the length of the drift region and the high electric field which normally exists at the drain end of the thin gate oxide is reduced.  The voltages applied to the gate, substrate and drain electrodes combine to deplete the drift region, first beneath the intermediate oxide and secondly as the drain voltage is further increased depletion occurs beneath the thick barrier oxide thereby distributing the drain voltage in a controlled manner.  By grading the thickness of the oxide layer between the source and drain and by covering a portion of this oxide with a gate electrode, avalanche breakdown of the device can be avoided up to an operating voltage exceeding that of diffused junctions. Indeed using the graded oxide thicknesses and optimizing other structural parameters, plane junction breakdown at the junction between the drift region and the substrate is attained instead of the surface aided curved junction breakdown usually obtained with high voltage MOS power transistors of this type.                           - i -

Abstract: ABSTRACT    There is described an improved coal liquefaction quenching process which prevents the formation of coke with a minimum reduction of thermal efficiency of the coal liquefaction process.  In the process, the rapid cooling of the liquid/solid products of the coal liquefaction reaction is performed without the cooling of the associated vapor stream to thereby prevent formation of coke and the occurrence of retrograde reactions.  The rapid cooling is achieved by recycling a subcooled portion of the liquid/solid mixture to the lower section of a phase separator that separates the vapor from the liquid/solid products leaving the coal reactor.

Abstract: ACOUSTIC CALIPER TOOL            Abstract of the Disclosure An acoustic caliper tool is set forth in this disclosure.  In the preferred and illustrated embodiment, acoustic transducers propagating highly directional acoustic waves transmit signals which are reflected at the interface of the borehole.  An acoustic return signal is received.  An acoustic swept frequency having a specific linear rate of sweep is utilized.  The transmitted signal is mixed with the received signal; the frequency difference between the two is proportional to the wave transit time between  transmitter  and  receiver.   Distance  of  wave propagation  is  inferred by the  frequency difference. Utilizing transducer transmitter and receiver pairs at locations around the caliper tool, the hole diameter can then be measured.   Diametrically spaced pairs measure radial segments of distance to the borehole,  and the transit times are converted into distance.  The diameter of the tool is a fixed value.  The measures are summed thereby yielding the diameter of the borehole.

Abstract: Abstract:   A method of reconstructing a synthetic aperture radar image from data collected by such radar carried by an aircraft or satellite involves azimuth compression processing by determining Doppler rate time change data and determining azimuth coordinates transformation data of an image after range compression.  This is done by resampling position designation data from the Doppler rate time change data and resampling the image after range compression in the azimuth direction using the azimuth coordinates transformation data, while keeping unaltered the Doppler rate of a point image relating to the image after coordinates transformation irrespective to the position in the azimuth direction inside the scene.  Thereafter FFT is used.
