Granted: 1991-01-02
Abstract: Abstract of the Disclosure An  improved  vascular  catheter  for  angioplasty providing   a   variable   stiffness   lengthwise   of the catheter.   A  relatively stiff  shaft portion  is provided for   transmitting   the   necessary   axial   forces   for advancing  the  catheter  along  a guide  wire  through  a series  of  sharp bends  to  the  arterial  branch  for dila-tation,  and  a more  flexible waist portion connects  from the  shaft  to  the  balloon and  tip portion.   This  allows the  tip  and  balloon  portions  to  follow  sharply  bending turns  in  the  guide  wire  without  the  shaft  portion tending to push the tip beyond a branch or dislodge the guide  wire.  A  set  of  such  catheters  may  be  provided for  a  surgical  procedure,  having varying  lengths of  the waist  portion  according  to  the  circumstances  of  the case.    If  a  sharp  turn  is  encountered  that  cannot  be tracked,   the  catheter  can  be  withdrawn  leaving  the guide  wire  in  place,  and  another  catheter  of  the  set having  a  longer  waist  portion  can  be  inserted  to  suc-cessfully follow the turn.

Title: Directional detection in connection with faults in a power supply network
Inventor: NIMMERSJO GUNNAR
IPC: H02H7/26
Filed: 1987-04-07
Granted: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE     A method  and  a device  for directional detection of a fault on a power transmission line extending between two stations (P, Q).   In one of the stations (P) there is a travelling wave model which, by means of currents and  voltages  measured  in the  station,  calculates  the voltage  distribution  along  the line.   The  direction to a fault is determined by monitoring changes in cal-culated voltages in the two stations.  If a fault occurs between the  stations,  the voltage change occurring in a  station  (Q)  between  the voltage  existing prior to a fault and after a fault can be estimated as ¦.DELTA.Uq¦, and  the corresponding voltage change occurring in the other station  (P)  can be estimated as ¦.DELTA.Up¦ , whereby according to the invention the difference ¦.DELTA.Uq¦-¦.DELTA.Up¦>0 signifies a fault on the line side of the station (P), i.e.  a  fault  lying ahead  of  the measuring point.   A fault lying behind station P is evidenced when¦.DELTA.Uq¦-¦.DELTA.Uq¦<0.

Abstract: ABSTRACT OF THE DISCLOSURE     A roadside antenna  system permitting the transmission of data to  a vehicular navigation  system  and providing for the recalibration of positional data carried by the navigation system includes  an  antenna  structure  and  transmitter  system  which permits the data transmission signal to be broadcast in a wide pattern.   Meanwhile,  the  signal  that provides  for positional recalibration is broadcast in a high directivity signal or split beam.   The  positional  accuracy  of  the  navigator  system  is improved by  performing  the  positional  calibration  only when intercepting the narrow beam pattern.   Data  transmission  and reception can be carried out within a larger effective reception area without affecting the positional accuracy.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for inhibiting permeability damage of clay minerals-containing hydro-carbon formations in the vicinity of a well during steam injection and for improving the injectivity of steam into that formation.  That method comprises injecting a wet steam that comprises a sufficient amount of a source of ammonium ions to form an ammonium ion concentration of at least 0.01 N in the vapor phase condensate of the wet steam, a sufficient amount of either sodium bicarbonate, potassium bicarbonate, or mixtures thereof to raise the pH of the liquid phase of the wet steam to within the range of from 7.5 to 10.5; and a sufficient amount of a source of potassium ions to form a potassium ion concentration of at least 0.01 N in the liquid phase of the wet steam.  The ammonium ions serve to inhibit permeability damage of hydrocarbon formations containing clay minerals in the vicinity of the vapor phase of the injected wet steam and to improve the injectivity of the wet steam into the formation in the vicinity of the vapor phase of the injected wet steam.  The potassium ions serve, in the vicinity of the liquid phase to inhibit permeability damage of hydrocarbon formations containing clay minerals and to improve the injectivity of the wet steam into the formation.

Filed: 1988-08-30
Granted: 1992-08-18
Abstract: STEADY STATE SLIP DETECTION/CORRECTION    FOR A MOTOR VEHICLE TRANSMISSION            Abstract of the Disclosure A closed loop clutch pressure control effective during steady state (nonshifting) operation of a motor vehicle transmission for adjusting the scheduled clutch pressure to generate torque capacity substantially in the amount required to transmit the transmission input torque.  When significant slippage is detected, the pressure is adjusted upward to increase the torque capacity of the clutch.  If significant slippage is not detected over a period of specified driving cycles, the pressure is adjusted downward to decrease the torque capacity of the clutch. This results in a low frequency clutch pressure limit cycle which enhances the efficiency of the transmission control while maintaining the clutch slippage within acceptable limits.
