Abstract: Abstract of the Disclosure An apparatus and method for automatic detection of speech signals in the presence of noise including noise events occurring when speech is not present and having signals whose signal strengths are substantially equal to or greater than the speech signals.  Frames of data representing digitized output signals fromn a plurality of frequency filters are operated on by a linear feature vector to create a scalar feature for each frame which is indicative of whether the frame is to be associated with speech signals or noise event signals.  The scalar features are compared with a detection threshold value which is created and updated from a plurality of previously stored scalar features.  A plurality of the results of the comparison for a succession of frames is stored and the stored results combined in a predetermined way to obtain an indication of when speech signals are present.  In automatic speech recognizers employing the above-described speech detections, when such indication is-given, frames are further preprocessed and then compared with stored templates in accordance with the dynamic programming algorithm in order to recognize which word was spoken.

Abstract: ABSTRACT OF THE DISCLOSURE        By the maintaining an arylenesulfide prepolymer with a melt viscosity of 5 to 3,000 poise at a temperature of 245 to 290°C under a liquid-liquid two-phase separated state in a solvent for 1 to 50 hours, the molecular weight of said prepolymer is increased to a high to ultra-high value while the linearity of the polymer is retained.  Such high molecular weight poly-arylene sulfides provide highly heat-resistant thermoplastics useful for parts such as those for electrical instruments and motor vehicles.  The process provides a more economical way to produce markedly high molecular weight linear polyarylene sul-phides, without the necessity for cross-linking agents, on organic acid salts.

Abstract: ABSTRACT    An operating system in a digital computer environment is run as a virtual machine on a virtual resource manager.  In order to provide a more dynamic environment for the operating system, linkages are made between the operating system device drivers and the corresponding real and virtual devices of the virtual resource manager. This is accomplished by assigning a "token" to the virtual resource manager.  A device dependent information file corresponding to the device is created.  This file contains adapter dependent information including a hardware port address for the physical device.  The "token" is placed in the operating system device driver at the time it is initiated.  When the operating system device driver is "opened" to drive the device, it uses the "token" to communicate with the virtual resource manager device driver thereby accomplishing driver to driver binding.  This causes the virtual resource manager device driver to use the adapter dependent information in the special file corresponding to the "token" and placed in the process stack.

Abstract: 22                  52,787 ABSTRACT OF THE DISCLOSURE        A transformer differential relay which includes apparatus for speeding up the detection of a power trans-former internal fault condition to initiate breaker action which interrupts current through the transformer is dis-closed.  Presently,  conventional  transformer differential relays include a unit for each phase of the power trans-former  for  detecting  a  potential  internal  fault  in  a respective transformer phase winding and for generating a signal to operate a set of breakers.  This breaker opera-tion is  inhibited for current  inrush  conditions of the transformer.  However, a processing time is associated with the detection of such a current inrush condition.  Accord-ingly, the breaker operating signal must be delayed for at least this processing time in order for the inhibition to be effectuated.  For the case in which there is no current inrush condition, the breakers remain delayed in operation from the inception of a true internal fault.  The aforemen-tioned speed-up apparatus circumvents this time delay in breaker  operation  and  renders  breaker  initiation  for detected internal faults with response times on the order of 3-5 milliseconds.  In addition,  the speed-up apparatus is inhibited from responding to potential internal fault conditions which may arise from initial inrush or recovery inrush current conditions or an external fault condition with severe current transformer saturation.

Abstract: ABSTRACT OF THE DISCLOSURE                 This relates to a lock arrangement particularly  adapted  for  use  in  locking together closure panels of paper board cartons and the like.  The lock arrangement utilizes a conventional basic type of lock including a primary locking  tab and a secondary locking tab.   The primary locking tab engages in a cutout  having  as  part  of  its  boundary  a straight line primary locking shoulder.   The new  feature of  the  lock  arrangement  is  an arrangement   for   receiving   the   secondary locking tab.  This arrangement is in the form of a cut line which will define an opening through the associated closure panel and also define a secondary locking ear for engagement beyond a prong on the secondary locking tab. The closure panel in which the cutout and the cut line are formed is provided adjacent the cut line either with an opening or a hinged locking  flap  with  there  being  between  the cutout and either the opening or the locking flap  a  narrow  strap.   When  a nose of the secondary  locking  tab  engages  the  panel between the narrow strap and the cut line, the panel is locally bowed through a twisting of the narrow strap facilitating the opening of the  panel  along  the  cut  line so  as  to automatically   receive   the   nose   of   the secondary locking tab.
