Abstract: Coarticulated  speech  segment data  are  extracted from spoken carrier syllables and digitally compressed for storage using  adaptive differential  pulse code modulation (ADPCM).   Beginning  seed quantization  and PCM values are generated for each coarticulated speech segment and stored together  with  the  ADPCM  encoded  data  in a  coarticulated speech segment library.   ADPCM encoded data are recovered from the coarticulated speech segment library and blown back using  the  initial  quantization  and  PCM  seed  values  to reconstruct and concatenate  in real  time  the  sequence of coarticulated speech segments required by a text to speech program to generate a desired high quality spoken message. In   the   preferred   embodiment  of   the   invention,   the coarticulated speech segments are diphones.

Title: Multi-element, bi-directional valve seat
Inventor: ANDERSON VAUGHN R
IPC: F16K5/06
Filed: 1989-01-30
Granted: 1993-08-31
Abstract: ABSTRACT OF THE DISCLOSURE     In  a  bi-directional  valve  control  system,  a differential, bi-directional valve sealing member for operation at  a  seating  surface wherein the seating member comprises a multi-membered disk formed of at least first and second contiguous disk elements.   The first disk element is formed of flexible material which is capable of primary deformation in response to fluid flow  along  a  flow  line  direction  corresponding  to second-to-first  disk  orientation.    This  first  disk element is configured in size and shape to increase seating contact at the seating surface by flow-pressure assist principles which cause the primary deformation response.    The  second  disk  element  is  formed  of flexible material which when combined with the first disk element is  less  capable of deforming than the independent  deformation  first  disk  element.    This second disk element resists  the primary deformation response with respect to fluid flow along the opposing flow  line  from  first-to-second  disk  element orientation.     The  resistance  against  primary deformation of the first disk element provides enhanced seating contact by pressure assist principles.

Title: Process for the production of nitriles and oxides
Inventor: RAMACHANDRAN RAMAKRISHNAN
IPC: C07C253/26
Filed: 1989-02-15
Granted: 1997-09-02
Abstract: An improved process is provided for the production of nitriles and oxides from hydrocarbons  by  reaction  with oxygen, air or a gas enriched in oxygen relative to air, preferably the latter,  and ammonia  where  a  nitrile  is desired,  in  the  presence of  a suitable  catalyst.   An alkane,  e.g.  propane,  is  converted  to  an  alkene  in  a dehydrogenator.  The product stream is introduced into an ammoxidation/oxidation   reactor.    The   product   formed therein is recovered in a conventional quench tower.  The gaseous effluent from the quench tower is treated in a PSA unit to form a gas stream containing the unreacted alkane and alkene as well as a minor amount, i.e. less than about 1 percent by volume, of osygen and nitrogen, if present in the feed to the ammoxidation/oxidation reactor.  The gas stream, which may or may not contain hydrogen depending on the  adsorbent  in  the  PSA unit,  is  introduced  into  a selective oxidation unit to remove the remaining oxygen and then recycled to the dehydrogenator.  Hydrogen may be introduced into or removed from the PSA effluent, depending on the function of the adsorbent therein, to obtain an optimum concentration for introduction into the dehydrogenator.  A particularly preferred PSA system for use in the  subject  process  comprises  two  parallel  PSA  units containing different adsorbents such that the gas stream formed  in one contains  all of  the hydrogen in the gas phase from the quench tower.  The feed to the PSA units is divided  disproportionately  so that  the  combined  PSA effluent recycle streams contain the optimum concentration of hydrogen for the dehydrogenator.

Abstract: PHA 40530 21 8.2.1989 ABSTRACT Multifunction memory for digital television. A digital television processing section capable of picture enhancement, progressive scanning, and multiple picture-in-picture processing is provided. The preferred digital television processing section preferably comprises a picture enhancement processor (PEP), a progressive scan processor, a picture in picture processor, at least one multiplexing means, and a common memory means. The PEP broadly comprises a parameter control means, a memory input select means, and mixer for obtaining current video data, delayed video data from the common memory, and control information from the control means, and for processing the obtained data and information to provide a signal to the progressive scan processor. In various modes of operation, the mixer also provides the signal to the memory input select means which forwards the information to the common memory. The common memory is used as a field delay device and feeds a delayed signal forward to the progressive scan processor. The progressive scan processor then utilizes the current signal and the delayed signal to provide a non-interlaced display. The delayed signal from the common? memory may also be fed back to the mixer of the PEP so that noise reduction and/or cross-color effect reduction may be accomplished or so that stored pictures may be displayed. The picture-in-picture (PIP) processor together with a first multiplexer permits main and secondary (PIP) video data to be supplied as current video data to the PEP. Or if desired, up to nine PIPs may constitute the video field.

Abstract: AUTONOMOUS VISUAL-ATTRACTION ENHANCEMENT UTILIZING                 EDGE-ILLUMINATED PANEL                        ABSTRACT    The visual attractiveness of a variety of otherwise-autonomous articles may be significantly enhanced through the inclusion of an apertured, internally light-transmissive essentially solid and preferably peripherally light reflectively coated panel which is edge-illuminated and energized by elements self-contained with the article body.  Article apertures of distributed area, point size or both may be thusly illuminated.          Distributed-area display effects may be enhanced through aperture-aligned light-concentrative discontinuities formed in the panel.  Enhancement of point-display effects may similarly be achieved through point-aperture-aligned, light-concentrative point discontinuities likewise formed in the panel.  Point effects may also be enhanced through the employment of an end-illuminated, aperture-aligned, point-discontinuous optical fiber in conjunction with a subject apertured panel.      Bi-directional display effects in subject autonomous articles may be achieved by means of a layered panel having oppositely-projective surfaces.  For realizations where increased article thickness is tolerable, color-variation effects may be achieved by the inclusion of an illuminating optical-fiber array whose input ends are themselves illuminated through a multicolored filter ring rotatably-interposed in front of an originating light source.    Specific realizations of the present invention include greeting cards, key-chain medallions, campaign buttons, tree ornaments, dolls and picture-carrying plaques.

Abstract: TRUNKED RADIO REPEATER SYSTEM                          ABSTRACT          A digitally trunked radio repeater system provides substantial improvements in timeliness of channel acquisition and channel drop, and in reliability of critical control signalling.  The system uses a much higher digital signalling rate than is typically found in prior art systems, and uses a control channel to convey digital channel request and assignment messages between the central site and mobile transceivers.  The mobile radio transceivers transmit channel requests on the control channel (if no response is received, the mobile retries during a retry time window which increases in duration in dependence on the number of retries).  The mobile transceiver switches to a working channel in response to an assignment message received on the control channel. Subaudible digital signals transmitted on the control channel and on active working channels allow late entry, shifting to higher priority calls, and other advanced functions.  Message and transmission trunking capabilities are both present so as to maximize working channel usage without compromising channel access for high priority communications.  During transmission trunking, called and calling transceivers return to the control channel after each transmission (and called transceivers may be inhibited from transmitting) but grant higher priority to calls from the other transceivers being communicated with to ensure continuity over an entire conversation.  Additional functions and fault tolerant features further increase the versatility and reliability of the system.
