Abstract: IMPLANTABLE SHUNT SYSTEM AND METHOD OF ASSEMBLY                 ABSTRACT OF THE DISCLOSURE          A   surgically   implantable   shunt   system, including a flow control valve and an antechamber, is provided for controlling the release of entrapped body fluids.   The flow  control valve  includes  a pair of molded  plastic  bases  situated,  respectively,  adjacent to an inlet and an outlet of the valve, which bases are situated  within  a  flexible  encasement.   Each  base includes  an  outer housing,  a valve membrane carrier positioned within  the  housing,  and  a  flow  control member.  The flow control members each include a rigid nail-like  central  support  and  a  separate  flexible resilient membrane positioned on the central support.          A first flow control member is capable of selectively occluding the valve inlet, but is normally spaced from its base to permit free fluid flow through the inlet.          The second flow control member is generally arch-shaped and resiliently biased to contact its respective base generally along the outer edge of the membrane in a manner permitting only controlled one-way flow through the  valve.    The  antechamber  permits  injection  of medication into the shunt between a proximal catheter and the distal flow control valve, and pumping of the medication in either direction.   Additionally, a method for  assembling  the  shunt  system  in  a  quick and economical manner is provided, which utilizes tapered grommets  to  anchor components  in  place  prior  to adhesively securing tubing to the flexible encasement.

Filed: 1988-10-11
Granted: 1993-07-06
Abstract: ABSTRACT: Magneto-optical recording apparatus and energizing circuit for use in such a magneto-optical recording apparatus.     A magneto-optical recording apparatus provided with a magnetic field modulator (8) is revealed.           The magnetic-field modulator (8)  comprises a field coil (18) for generating a magnetic field and switching means (11,12,15,16,22) for coupling at least one terminal (17) of the magnet coil (18) to a first potential point (10) at a first potential (Vp) or a second potential point (14) at a second potential (Vn) depending on the logic value of a control signal (Vs), in order to produce in the field coil an alternating current whose polarity depends on the logic value. The field coil (18) is arranged in a parallel resonant circuit (18,21). The switching means comprise means (12,16) for inhibiting, after the terminal (17) has been uncoupled from one of i the potential points (10,14), decoupling to the other potential point for a time interval corresponding to half the resonant period of the resonant circuit (18,21). This magnetic-field modulator provides a very rapid reversal of the current through the field coil.

Title: Polymeric compositions
Inventor: FARRAR DAVID
IPC: C02F1/52
Filed: 1989-01-30
Granted: 1998-05-05
Abstract: Water absorbent particulate polymers and their uses are described. Friable aggregates may be made by bonding substantially dry polymer particles with an aqueous liquid and drying the aggregates. These aggregates can be broken down to the individual polymer particles upon mixing with an aqueous medium and thus can have the flow properties of relatively coarse particles and  the  performance  properties  of  relatively  fine particles.   They may be soluble and used as flocculants or viscosifiers or binders for,  for instance,  iron ore pelletisation.   Alternatively they may be swellable and insoluble,   for   instance   for  converting   a   sticky particulate mass  (such as coal fines filter cake)  to a crumbly solid.   When pellets are formed by compression moulding  from  a  crumbly  solid  made  by  mixing  water absorbent  polymer  particles  with  a  sticky  mass  of inorganic particles  (such as a coal fines filter cake) improved  properties  are  obtained  when  the  absorbent polymer  particles  are  introduced  in  the  form  of  a dispersion in water-immiscible liquid.

Abstract: MOVING DATA STORAGE MEDIA MODE/DIRECTION          CHANGE OPTIMIZATION                         ABSTRACT    The moving data storage media mode/direction change optimization apparatus makes use of information received concerning the mode and direction of the next operation to be performed by the data storage system to efficiently reposition   the   media   in   a   single   repositioning operation.  In the case where the data storage media is a magnetic tape, the tape control unit receives information concerning the mode and direction of the next operation to  be  performed prior to  the  completion  of  the  tape transport  automatic  repositioning  cycle.    The  tape control  unit  signals the tape  transport  to  abort  the standard repositioning operation and instead to initiate a  new  repositioning  operation  which  repositions  the magnetic tape based on the mode and direction of both the presently  executing  operation  and  the  next  operation. This use of a single repositioning operation, taking into account the mode and direction of the timewise subsequent operation,  significantly  reduces  the  amount  of  time required  to  reposition  the  magnetic tape  to  a  point appropriate for the next operation.
