Abstract: SINGLE-USE SYRINGE HAVING MIS-USE        RESISTANT FEATURES ABSTRACT A syringe assembly includes a barrel having an inside surface describing a chamber for retaining fluid, an open proximal end and a distal barrel end having a passageway therethrough in fluid communi-cation with the chamber.  A plunger rod includes an elongate body portion, a proximal end and a distal end with a stopper at the distal end.  The stopper is slidably positioned in fluid-tight engagement in the barrel.  A locking element is positioned in the barrel  between  the  plunger  rod  and  the  inside surface of  the barrel.   The  locking element  in-cludes at least two proximally and outwardly facing non-parallel locking barbs, a distally and inwardly facing  resisting  edge  and  an  inwardly  facing driving  edge.   The  driving  edge  is  adapted  to interact with the plunger rod to move the locking element along the barrel as the stopper is advanced distally along the barrel.  The resisting edge and the locking barbs are adapted to prevent proximal motion  of  the  plunger  rod  with  respect  to  the barrel after initial distal motion of the plunger rod to expel fluid through the passageway wherein proximal motion of the plunger rod with respect to the barrel causes the resisting edge to engage the plunger rod causing the locking element to move in a  proximal  direction  wherein  the  locking  barbs engage the inside surface of the barrel to prevent further movement and allowing only distal movement of the plunger rod with respect to the barrel.

Abstract: A vertical foam wrapping machine can rewrap rolls of carbonless paper having damaged packaging in satellite locations without the need for returning the rolls of paper to the manufacturing facility for rewrapping. The machine includes a lift device with a vertically adjustable arm. Foam wrap and stretch film are positioned on this arm and are fed to the roll of carbonless paper resting on a turntable in front of the lift device. The turntable has a rigid platform upon which the paper sits. This platform is nonmovable relative to the turntable and has a diameter less than the diameter of the roll of paper. In this manner, a lower section of the roll of paper adjacent the lower edge remains exposed. As the turntable rotates, foam wrap and stretch film are wrapped around the roll of paper. Due to the exposure of the lower edge, the foam wrap and stretch film can cover this lower edge. Accordingly, bath the lower and upper edges of the roll of paper can be wrapped with protective foam wrap and stretch film. If a long roll of paper is on the platform, the support arm can be raised or lowered to spirally wrap the roll. This machine can also be used for originally wrapping the roll of paper with foam wrap and stretch film and a hold down device can be used to lock small or light rolls of paper onto the turntable.

Title: Fast algorithm for deriving acoustic prototypes for automatic speech recognition
Inventor: BAHL LALIT R
IPC: G10L15/06
Filed: 1992-05-05
Granted: 1996-10-29
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.

Title: Cryogenic process for producing ultra high purity nitrogen
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1992-06-04
Granted: 1997-03-18
Abstract: This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein an ultra high purity nitrogen product is generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Ultra high purity, e.g., nitrogen having less than 0.1 ppm of light impurities is generated with enhanced nitrogen product recovery by withdrawing liquid nitrogen from a first column at an intermediate point and charging that fraction as feed to the second column, withdrawing a nitrogen stream which is rich in volatile contaminants from the top of the first column, partially condensing that nitrogen stream against crude liquid oxygen, and removing the uncondensed portion which has been concentrated in volatile contaminants as a purge stream.  An ultra high purity nitrogen product is obtained from a second column.
