Patent CA-2046444-A1 (CA)
Inventor: SOEHENDRA NIB
IPC: A61M25/00
Filed: 1991-07-08
Abstract: A technique for removing an implanted stent and a device useful therefor.  An endoscope is introduced into position at the proximal end of the implanted stent and a cannula is then introduced through the endoscope.  A wire guide is then passed through the cannula and into the duct through the lumen of the stent which is to be removed.  The cannula is then removed and a stent retrieval cable is advanced over the wire guide and into position at the proximal end of the stent.  The stent retrieval cable is torqueable, and has a tapered thread at its distal end and a rotation dial at its proximal end.  Once the retrieval cable has been placed into position, the rotation dial is turned to engage the threading into the lumen of the stent.  After the stent has been attached to the retrieval cable in this manner, the stent and cable are removed together through the endoscope and out of the body, leaving the endoscope and wire guide in place for use in the implantation of the replacement stent.

For instance, the rubbery polymers of this invention can be made into tire treads which exhibit outstanding traction characteristics while maintaining good rolling resistance and tread durability.  This invention more specifically reveals a rubber polymer which has an excellent combination of properties for use in making tire treads which is comprised of repeat units which are derived essentially from at least one conjugated diene monomer, wherein the first segment has a number average molecular weight which is within the range of about 25,000 to about 350,000; and (b) a final segment which is comprised of repeat units which are derived from 1,3-butadiene, isoprene, and styrene, wherein the repeat units in the final segment are in essentially random order, and wherein the final segment has a number average molecular weight which is within the range of about 25,000 to about 350,000.

Abstract: An apparatus for generating a set of acoustic prototype signals for encoding speech includes means for storing a training script model comprises a series of word-segment models.   Each  word-segment  model  comprises  a  series  of elementary models.  Means  are provided  for measuring the value  of  at  least  one  feature  of  an utterance  of  the training script during each of a series of time intervals to produce a series of feature vector signals representing the feature values of the utterance.   Means are provided for estimating at least one path through the training script model which would produce the entire  series of measured feature  vector  signals.   From  the  estimated  path,  the elementary model in the training script model which would produce  each feature  vector  signal  is  estimated.  The apparatus further comprises means for clustering the feature vector signals into a plurality of clusters.  Each feature vector  signal  in  a  cluster  corresponds  to  a  single elementary  model  in  a  single  location  in  a  single word-segment model.  Each cluster signal has a cluster value equal to an average of the feature values of all feature vectors  in the  signal.   Finally,  the  apparatus  includes means for storing a plurality of prototype vector signals. Each prototype vector signal corresponds to an elementary model,  has  an  identifier,  and  comprises  at  least  two partition  values.   The  partition  values  are  equal  to combinations of the cluster values of one or more cluster signals corresponding to the elementary model.

Abstract: A seating and sealing insert for mounting a heated injection molding nozzle in a well in a mold. The hollow insert has a cylindrical central portion extending between a rear seating portion and a forward sealing portion. The rear seating portion is outwardly flanged to seat in the well in the mold and forms an inner seat to receive a cylindrical support flange of the nozzle to accurately support the nozzle in the well in the mold. The forward sealing portion has a V - shaped forward face and inner and outer surfaces which are forced outwardly by melt pressure to seal against the nozzle and the mold. Thus, the seating and sealing insert provides an insulative air space between the heated nozzle and the surrounding mold and the forward sealing portion prevents the escape of pressurized melt into the insulative air space.
