Title: Method for reducing the influence of distortion products
Inventor: ERHAGE LARS I
IPC: H03M1/12
Filed: 1992-01-31
Abstract: ABSTRACT            A method for reducing the influence of distortion products that are formed in conjunction with the analogue-digital-conversion (14,15) of samples of an electric signal (IF), from which signal two quadrature signals (I,Q) are formed prior to the conversion process. The quadrature signals are phase modulated (16-20) prior to the conversion process and are phase demodulated (20-22) subsequent to this conversion process, by phase-shifting the signals by a value (.PHI.n,-.PHI.n) which is changed randomly for each new sample.  The energy content of individual distortion products is distributed over a broadband in this way. This is due to correct demodulation of the useful signal, i.e. the fundamental tone, whereas harmonics and intermodulation products will have a residual phase modulation subsequent to the phase demodulating process.

Inventor: CHANG SHIN-CHIO
IPC: G06F17/30
Filed: 1991-08-26
Abstract: An adaptive record ranking method for full text information retrieval, which quantifies the relevance of retrieved records to query terms occurring in said record. The method utilizes a multilevel weighting technique which permits user input to affect record weighting at each level of the ranking process. The method utilizes weighted attributes of properties of terms occurring in the records of the data base and compensates for the distance between adjacent words of complex terms. The method has been implemented on large full text data bases and the resulting rankings achieve a relatively high level of precision in ranking the relevance of retrieved records to a user query.

Abstract: ABSTRACT            An apparatus and method for recanalization of a blood vessel obstruction by application of low frequency mechanical energy to a vessel site or by creation of cavitation at the vessel site. The system includes a catheter assembly having a wire located within and extending through a wire support tube and adapted to move axially therewith.  A driving apparatus positioned at a proximal portion of the catheter assembly imparts energy to the wire to oscillate it axially.  A tip is connected to a distal end of the wire and imparts low frequency mechanical energy or causes cavitation at the vessel site to recanalize it. Further, a fluid particle removal system can be incorporated within the catheter assembly to convey pressurized fluid via the wire support tube to the tip where the fluid is redirected in a proximal direction into a second tube of the catheter assembly coaxially positioned around the wire support tube.  Particulate from the vessel obstruction being recanalized becomes attached viscously in the redirected pressurized fluid and is withdrawn from the vessel site.

Title: Frost-proof drive shaft for water meter
Inventor: BRUNSON CHARLES P IV
IPC: G01F15/10
Filed: 1993-05-27
Abstract: Abstract FROST-PROOF DRIVE SHAFT FOR WATER METER An  improved  drive  shaft  for  a  positive  displacement type water meter includes  a  flexible spring arm formed on one end of the shaft for engaging the drive  spindle  of  a  nutating  disk  measuring element disposed within a water meter.    The  other  end  of  the  drive shaft is connected to a magnetic drive which,  in  turn, is magnetically coupled to a conventional mechanical register. Under  normal  conditions, the nutating disk measuring element and drive spindle oscillate  in  the  water meter at a rate proportional to water meter flow.  The drive  spindle engages the spring arm of the drive shaft causing the drive shaft and  magnet  to rotate.  The magnet is coupled through the water meter casing to a  second  magnet  in  the  register.   Rotation of the second magnet is used to drive  the  mechanical register to register water consumption.  In the event the first  magnet  within  the  meter casing becomes frozen to the casing because of external  freezing  conditions,  the  drive  spindle will snap past the flexible spring  arm.    This  prevents  damage to the drive shaft and first magnet which would otherwise occur with conventional drive shaft arrangements.

Title: Grubber Tine
Inventor: SKJAEVELAND MAGNE
IPC: A01B61/04
Filed: 1993-07-15
Abstract: The invention relates to a grubber tine of a tubular cross-section which, as compared to known grubber tines, gives reduced weight and larger flexure and vibrations when moved through the soil, which gives reduced tractive power.  The grubber tine is adpated to escape obstacles within the soil in that the grubber tine is pivotally suspended on a shaft.  Boss means is/are attached to the grubber tine through friction forces between boss means and grubber tine at a preferably conical contact face, achieved in that the boss means is/are pressed into holes in the wall of the grubber tine.  In the working position, the grubber tine rests against a shaft and is kept in place by means of a safety bolt adapted to be stretched off upon the occurrence of overload.  The safety bolt may be combined with a resilient member, such that the grubber tine to a certain degree may yield upon load and then return to working position.  Alternatively, the safety bolt may completely be substituted by a biased spring allowing the grubber tine to rotate around the shaft, escaping obstacles and passing over possible obstacles, thereafter returning to working position by means of the spring force.
