Abstract: Abstract of the Disclosure Purification of the exhaust gases  of diesel engines, particularly for motor vehicles, by a device with a plurality of macrocells in a substrate of porous ceramic.  The macro-cells preferably are small channels (10,11) which are mutually parallel, in a monolithic ceramic body (8).  Some of the channels (10,11) are open upstram and others are open down-stream.  The channels (11) which are open upstream are filled with an insert body (13) of compacted metal threads, which support catalytic material.  Such a device, connected into the exhaust line of a diesel engine, forms a carbon filter, which is distinguished by high filter action with a relatively lower exhaust-gas counterpressure and a relatively low carbon combustion temperature.

Abstract: WAVEFORM CLIPPING CIRCUITS Abstract of the Disclosure A soft clipping circuit for a telephone subset limits the output signal amplitude to the line thus preventing output stage saturation with consequent reduction in impedance. The circuit includes a variable gain input stage (I/P), a main speech signal amplifier (AMP1) and a rectifying amplifier feed back stage (AMP2) that generates a control current whenever the output speech signal exceeds a predetermined threshold. This current is fed to the input stage so as to reduce its gain. Typically the input stage comprises a long tailed transistor pair amplifier, the control current being fed to the tail of the pair.

Abstract: METHOD AND APPARATUS FOR RECORDING AND REPRODUCING AN ANALOG SIGNAL                    ABSTRACT OF THE DISCLOSURE     For  recording  an  analog  signal  by  means  of  two recording heads equally spaced on a rotating drum,  a magnetic tape is wrapped guide drum with an angular range of 90°, so that there are recording periods when a head is tracing the tape and free periods when neither head is tracing the tape.  The analog signal to be recorded is converted to pulse code modulated (PCM) signals  having  real  time periods  longer  than  the  recording periods.   The  free periods,  during which neither head  is  in contact with the recording medium, are used to add redundant data such as parity data and a cyclic redundancy check (CRC) code to the PCM signals.  The composite signal, which represents a PCM signal having the parity data and CRC code added to  it,  is time-base  compressed  to  a  period  substantially  equal  to  the recording periods and is recorded on the recording medium by one of  the heads during its  recording period.   To reproduce  the signal, the same head arrangement is used.  The free periods are used  for  error  correction  and  the  error-corrected  signal  is time-base expanded to occupy the original or real time signal period and then reconverted into the corresponding analog signal.

Abstract: ABSTRACT            In a bio-reactor for the treatment of sewage waters or se-wage sludges the air is fed by means of a subsurface aera-tor into its upper part and the microbubbles produced are transported with a defined velocity of flow into the lower horizontal part of the reactor. In the riser part of the reactor pulsations and microwhirls are produced in order to hinder the coalescence of the microbubbles and to increase the rate of exchange between gas and liquid.            The reactor comprises a downcomer part, the section of which being many times smaller than the one of the riser part.  In the upper part a subsurface aerator is arranged and in the riser part there are provided corrugated-pipe-similar obstacles for producing pulsations and microwhirls.          The device further comprises a heat exchanger as well as an adjusting and control device for the water, respeetively the gas inlet. The water outlet comprises an outgassing de-vice. If necessary, an agitator may be included.          With such a process it is possible to reduce the volume of the construction and the expenditure of energy while the entered oxygen power is many times enhanced and a maximum utilization of the oxygen is obtained.

Abstract: FABRIC MOUNTING TRACK SYSTEM     ABSTRACT    A fabric mounting track system which permits to mount a fabric to cover a wall without the need to utilize weltings and other devices to cover unsightly parts of the system.  The fabric mounting track consists of two parts, a back support plate and a hinge lock plate.  The hinge lock plate has a straight portion at one end and a substantially circular portion at the other end forming a hinge.         The hinge is disposed in a plane spaced from the straight portion.  The back support plate also has a substantially circular portion at one end forming a larger hinge into which the smaller hinge of the hinge lock plate fits.  Extending from the straight portion of the back support plate at an acute angle is a ledge, while the other end terminates in a straight portion forming a small angle, and may have its free end extending in the opposite direction.  The hinge lock plate is provided with substantially equally spaced lancings punched out from the straight portion of the hinge plate.          At intervals between a number of lancings, one of the lancings is larger in size.  It will pierce the fabric to support it while the back support plate is hanging down from the hinge lock plate.          Thereupon the hinge lock plate is rotated 180° so that the large size lancings will hook behind the ledge, while the small size lancings will impact the free end of the ledge , thereby forcing the fabric through the lancings.  The lancings now support the fabric.  The mounting track is capable of withstanding a fabric pull of at least ten to twelve pounds per inch and may withstand as much as twenty pounds' pull per inch.  Various modifica-tions of the fabric mounting track are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE          A dual lumen cannula for use in haemodialysis has an improved leading end to facilitate insertion and an improved coupling for connection to blood extraction and return tubes.   The improved leading end has a conical tip centered on the longitudinal axis of the cannula and, in the leading end, the extraction lumen is blanked off by using an insert to prevent blood flow downstream of the extraction lumen, and to minimize blood stagnation and damage.  The improved coupling is generally Y-shaped and the extraction and return lumens of the cannula terminate in conical shaped ends which receive extraction and return tubes with similar shaped ends.  The ends of the extraction and return tubes have minimal thickness so that when inserted the interior surfaces of the cannula lumens and the tubes merge smoothly to minimize blood impact problems.  Methods of manufacturing the tip and a Y-shaped connecting piece for connecting the dual lumen cannula to tubing are also described.

Abstract: Abstract of the Disclosure A modified spin echo sequence is employed to identify fluid movement in a material.  The volume of interest is subjected to a static field along one axis (Z) and an RF magnetic excitation pulse transverse to the static field is applied which tilts the nuclear spins in the volume.          The tilted nuclear spins are then allowed to process about  the uniform static field in the presence of a gradient  field whereby  the nuclear  spins become  de-phased.  Thereafter, a spin echo of the static spins is created by either a 180° Of pulse or reversal of the gradient field. Upon refocusing of the static nuclear spins a restoration RF pulse is applied to realign the stationary nuclear spins with the static field.  Nuclear spins undergoing bulk motion as in fluid flow will be refocused to a different phase than the stationary spins so that the final RF pulse will in general leave these spins with a non-zero transverse magnetic moment.  This residual transverse magnetic moment is then detected to identify the fluid movement.
