Abstract: Abstract of the Disclosure:        In an encoder device which is for use in combination with a decoder device in a communication system and which encodes a sequence of digital speech signals into a sequence of output signals by the use of a spectrum parameter and pitch parameters, a primary pulse producing unit calculates a first set of prediction excitation multipulses by the use of the spectrum parameter and the pitch parameters with respect to a preselected one of subframes which result from dividing every frames and produces the first set of prediction excitation multipulses and a sequence of primary synthesized signals specified by the first set of prediction excitation multipulses and the spectrum parameter and the pitch parameters.  A subtracter substracts the primary synthesized signals from the digital speech signals and produces a sequence of difference signals representative of differences between the primary synthesized signals and the digital speech signals.  Supplied with the difference signals, a secondary pulse producing unit calculates a predetermined number of secondary excitation multipulses by the use of the spectrum parameter and the pitch parameters.      Alternatively, the encoder device may comprise a periodicity detector supplied with the spectrum (Abstract of the Disclosure continued) parameter for detecting whether or not periodicity of an impulse response of a synthesis filter determined by the spectrum parameter is higher than a predetermined threshold level.  The periodicity detector produces a weighting signal representative of a weighted value when the periodicity is higher than the predetermined threshold level.  The spectrum parameter is weighted on production of the weighted signals.

Title: Pyrolysis process and apparatus
Inventor: AGARWAL KEDAR B
IPC: C08J11/00
Filed: 1990-09-19
Granted: 1997-08-19
Abstract: A process and apparatus for the continuous pyrolitic decomposition of a feed material having an organic and an inorganic component and recovery of the inorganic component, carbon-free, for reuse in essentially the same material as from which it originally emanated.  The apparatus includes a reactor assembly for receiving and pyrolitically decomposing the organic component of the feed material.  The reactor assembly includes a screw-type conveyer assembly wherein the flights which convey the residue through a housing have openings therein to allow gaseous decomposition products to pass therethrough to preclude pressurization of the housing by the decomposition products.  The inorganic residue has carbon thereon and is cooled to an oxidation temperature in a non-oxidizing manner in a first cooling assembly.  Without admitting ambient air into the cooling assembly the cooled residue is transferred to an oxidation assembly where the carbon is oxidized to form gaseous carbon dioxide and is liberated from the inorganic residue.  The inorganic residue is then cooled in a second cooling assembly and thereafter collected for reuse.  The decomposition products are further processed in a condenser assembly wherein all condensable material is removed and the gaseous products are collected for reuse.  The gaseous products are preferably used to fire the reactor assembly.

An eyelid displacing member is coupled to the outer casing and slideably mounted through the inner casing.      The eyelid displacing member includes a depresses tab adapted to engage the facial tissue below an eye. The depressor tab engages the facial tissue upon moving the outer casing toward the inner casing, thus discplacing the lower eyelid to expose the ocular cul-de-sac. A dispensing member is adapted by the outer casing. The dispensing member is adapted to actuate the ocular vial upon moving the outer casing toward the inner casing, to release medicament onto the expose ocular cul-de-sac of the eye.
