Abstract: VACUUM FORMING PROCESS FOR DEEP DRAWN PLASTIC ARTICLES            ABSTRACT OF THE INVENTION        An improved vacuum forming process for forming a deep drawn plastic article wherein a mold having a hollow cavity and a relatively thick outer shell mounted on a base forms the shape of the article. The shell has a plurality of small passageways through the outer surface connected to relatively large passageways within the outer shell and the passageways are connected to a vacuum pump. A sheet of hot plastic material is placed over the mold and a vacuum is drawn to form the plastic sheet into the shape of the mold to form the article. The improved process provides for a first large passageway interconnected to a plurality of small passageways through the outer surface of the mold outer shell in a first area of the mold outer shell that forms the deep drawn portion of the article and connected in flow communication with a vacuum pump. A second large passageway interconnected to a plurality of small passageways through the outer surface of the mold outer shell in a second area of the mold and connected in flow communication with a vacuum pump. A sheet of hot plastic material is placed over the mold and a vacuum is first drawn through the first large passageway to form the deep draw portion of the article and then a vacuum is drawn through the second large passageway. This improved vacuum forming process provides for thicker material in the deep draw portion of the article than the rest of the article.

Title: Clinically practical rotational angioplasty system
Inventor: AUTH DAVID C
IPC: A61B17/00
Filed: 1987-11-16
Granted: 1993-08-03
Abstract: ABSTRACT   CLINICALLY PRACTICAL ROTATIONAL ANGIOPLASTY SYSTEM     The present invention is a clinically practical, rotational  angioplasty system which employs  a unique rotary ablative device for mechanically abrading,  and thereby  removing,  lesions from  within  a patient's vessels.   The  device,  called  a  "Rotablator"  by its inventors,  has  a  gas  driven  prime  mover  with  an integrated water pump and fiberoptic tachometer.  The prime mover is connected,  via a hollow helical drive assembly,  to  an ellipsoidal,  rotating,  ablative burr which is  used  for  the  actual  recannilization of the patient's vessel.  The burr is provided with a central opening therethrough,  which,  together with the hollow drive assembly, permits the burr and drive assembly to be  threaded  over  a  guide  wire  similar to  the  type conventionally  used  in  a  catheterization  procedure.       The  drive  assembly is located within a hollow sheath which prevents the rotating drive assembly from contacting the inner walls of a patient's vessel.  The lumen which is created between the drive assembly and the  sheath is  connected to  a water pump within the Rotablator,  and,  in use,  saline pumped through this lumen serves to lubricate and cool the rotating drive assembly. The  fiberoptic  tachometer  uses  a  fiber  optic cable assembly for determining the rotational speed of the air driven turbine.  Accordingly, there is no direct electrical connection between the Rotablator drive unit and  any  electrical  power  supply,  whereby  assuring complete  patient  isolation   from  electrical  power supplies.       A control box is used to control the rotational speed of the angioplasty burr, with feedback provided to the electronics by means of the fiber optic tachometer.     A foot control may be used by the physician conducting the angioplasty, to turn on the prime mover.

Abstract: INVENTOR: HEINZ PICCOLRUAZ          INVENTION: TARGET TRACKING SYSTEM                    ABSTRACT OF THE DISCLOSURE           The target tracking system has high tracking reliability at small servo load and comprises a plural number of groups of target sensors having tracking signal travelling times which vary from one group to the other and defining respective lines of sight, a servo system causing the lines of sight to track the target,  a target estimator for estimating the movement of the target, a servo estimator for estimating the movement of the servo system, and a regulator which identically controls the servo system and the servo estimator such that the vectorial difference between the estimate of the target movement and the estimate of the servo movement is caused to approach zero.  During the target tracking operation, vectorial target deviation signals which are generated by groups of angle sensors, are processed by multipliers using respective matrices in order to produce related combined target deviation signals.  The thus processed vectorial target deviation signals are directly applied to the servo system and the servo estimator in a manner as if there would be present only one respective angle sensor producing the combined target deviation signal.

Granted: 1994-09-20
Abstract: ABSTRACT OF THE DISCLOSURE       A method of manufacturing a superconducting wire is carried out by first preparing a material being composed of Y1Ba2Cu3O7.  This material is heated/molten in a platinum crucible.  A melt thus obtained is drawn out from a hole provided on the bottom wall of the crucible to be linearly discharged.  The linearly discharged melt is cooled to be solidified. A cooling/solidifying space for such a step is set at a temperature level lower by about 10°C than the solidifying point of the material, and a slow-cooling zone is provided next to the cooling/solidifying space.  This slow-cooling zone is provided to be at a relatively high temperature in a portion closer to the hole while having a temperature gradient along a direction for linearly discharging the melt.  A superconducting wire being composed of Y1Ba2Cu3O7 is thus obtained.  This superconducting wire superconducts at 85 K.
