Abstract: IMPROVED HIGH PRESSURE OXYGEN-SATURATED        WATER TREATMENT APPARATUS               ABSTRACT OF THE DISCLOSURE         The  improved  high  pressure  oxygen-saturated water  treatment  apparatus  of  the  present  invention functions  to  provide  super-saturated  oxygen  treatment to waste water for purification thereof.   The apparatus includes a pressurized treatment tank having a substantial longitudinal dimension  with a chamber separation plate forming two interconnected chambers in the tank.  An input conduit for flowing waste water into the first chamber of the  tank  is  provided.    An  oxygen  input  conduit  is connected to the tank for providing oxygen-containing gas under substantial pressure within  the  tank.   An oxygen output conduit is also disposed on the tank for receiving the   oxygen-containing  gas  from  the  tank  to  form  a pressurized oxygen-containing stream.   A venturi is also disposed  on  the tank  for  receiving  and  combining  the pressurized  oxygen-containing  stream  with  recirculated water from the tank to form a combined injection stream of pressurized water which is super-saturated with oxygen, and  which  is  then  injected  into  the  treatment  water contained within the tank.  As the tank is maintained at a pressure  lower  than  that of  the  injection stream,  the pressurized oxygen comes out of solution in tiny bubbles preferentially about particles of solid waste to entrain and provide supplemental floatation thereto.   The result is  to  substantially  oxidize  any  oxidizable  material contained within the tank.   The  treated  water  is then removed by suitable means from the tank from the second chamber thereof.

Abstract: ABSTRACT           A precast concrete culvert system includes a series of open  bottom  culvert  sections  each having parallel  spaced vertical side walls integrally connected to an arcuate top wall having a curved inner surface with a radius of curvature at least twice the rise defined between the top center of the curved inner surface and the bottom surfaces of the side walls.          The side walls rest on footers and have outer surfaces which form sharp corners with the top surface of the top wall and have a vertical height at least sixty percent and preferably between eighty and ninety percent of the rise.  The vertical height is also less than fifty percent of the radius of curvature which is between  twenty and fifty feet and preferably either about twenty-five or forty feet.  The end sections have vertical head walls, and the vertical side walls are adapted to connect with angularly disposed vertical concrete wing walls to provide for a smooth hydraulic flow into and through the series of the culvert sections.  Culvert sections may also be precast with a taper to form a curved conduit or be precast with end walls to form an underground  tank  or  be  precast  with parallel  spaced  and outwardly projecting end ribs.

Abstract: TELECOMMUNICATIONS LINE INTERFACE CIRCUITS          Abstract of the Disclosure A two-wire telephone line interface circuit includes two transformers each having primary and secondary windings.  The primary windings, which are divided into equal halves for balance and d.c. feed purposes, are connected in series between the two wires, and the winding resistances together with optional series resistance provide desired d.c. resistance across the line.  To this end one or both of these windings may comprise resistance wire.  A signal from a receive line is coupled to the two-wire line via an amplifier whose low output impedance terminates the secondary of one of the transformers. Another amplifier couples a signal from the two-wire line and the secondary of the other transformer to a transmit line, and also provides at its input a transhybrid signal cancellation node, a transhybrid signal being coupled thereto via a balance impedance.  A feedback path can be provided for increasing the a.c. impedance presented by the interface circuit to the line.  A four-wire telecommunications line interface circuit using similar transformers is also described.                      - i -

Abstract: A system, which uses inertial measurement units, is shown for determining the position and orientation of a towed array of sensors used for target detection.  The system uses an onboard master inertial navigation system and  a  relative  position  determination  mechanism  to generate a first estimated position for each inertial measurement  unit  within  the  array.    Each  inertial measurement  unit  measures  force  and  angular  change information used by an onboard computer to create a second  estimated position by known methods  for each inertial sensor.   An error signal represented by the difference between the two estimated positions for each inertial unit is processed over time by a Kalman filter to reduce the error in the heading and attitude determined for each inertial unit to establish an accurate location for each inertial unit and, thus, the towed array of such units.

Abstract: ABSTRACT OF THE INVENTION     In accordance with the invention, a liner is created within a bore.  This liner may be a layer or layers of material applied to the internal surface of the bore.  Pressure is then applied to the internal surface of the liner preferably by the inflation of a packer or packer assembly whose length is substantially the length of the liner and which is maintained in place until the adhesive, which is usually a liquid, is cured.  It is round that the integrity of the liner is improved as compared to the case in which no such pressure is employed.  In addition, bonding of the lining to the bore wall is improved since pressure improves spreading of the adhesive applied therebetween.
