Title: Methods for speech quantization and error correction
Inventor: HARDWICK JOHN C
IPC: G10L19/08
Filed: 1991-12-04
Abstract: The redundancy contained within the spectral amplitudes is reduced, and as a result the quantization of the spectral amplitudes is improved. The prediction of the spectral amplitudes of the current segment from the spectral amplitudes of the previous is adjusted to account for any change in the fundamental frequency between the two segments. The spectral amplitudes prediction residuals are divided into a fixed number of blocks each containing approximately the same number of elements. A prediction residual block average (PRBA) vector is formed; each element of the PRBA is equal to the average of the prediction residuals within one of the blocks The PRBA vector is vector quantized, or it is transformed with a Discrete Cosine Transform (DCT) and scalar quantized. The perceived effect of bit errors is reduced by smoothing the voiced/unvoiced decisions. An estimate of the error rate is made by locally averaging the number of correctable bit errors within each segment. If the estimate of the error rate is greater than a threshold, then high energy spectral amplitudes are declared voiced.

Title: Transmission Shift Control Mechanism
Inventor: DANIEL TIMOTHY S
IPC: F16H61/24
Filed: 1993-09-14
Abstract: A shift control mechanism (41) is provided for use in cooperation with a transmission shift bar housing assembly (11) to be mounted on a transmission having a plurality of shift rails (17,19,21,23) of the type wherein movement of the shift lever in the Y-Y direction results in axial movement of one of the shift rails, and engagement of a particular transmission gear ratio. The shift controlmechanism includes a support member (43) and a slide member (45) restrained from movement only in the X-X direction relative to the support member, and in engagement with a shift finger (33). The support member and slide member define spring openings (53,55,73,75), which receive compression springs. When the slide member (45) is in a neutral position (FIG. 1) in the X-X direction, the compression springs are at minimum load; movement of the slide member toward a first displaced position (FIG. 4) further loads a first spring (57); and further movement of the slide member toward a second position (FIG. 6) further loads the second spring (59).
Patent CA-2106747-A1 (CA)
Inventor: HUANG CHING-TSVEN
IPC: G21F9/30
Filed: 1993-09-22
Abstract: The present invention discloses a method for preparing the inorganic hardenable slurry and the use of same in the solidification of wastes,  In addition to water, the essential parts of the slurry are inorganic components including borates, cement-base powder and other additives such as magnesium oxide, gypsum and silica.  The slurry is low in viscosity before solidification and flows freely, and within approximately 30 minutes after preparation the slurry becomes hardened into a highly solidified substance,  The solidification of the slurry is resulted mainly from reaction of borates and the cement-base powder and to obtain a best result the weight of borates must be the same as that of the cement-base powder or even higher than the weight of the latter.  The solidification mechanism differs entirely from the simple hydration reaction that brings about solidification of cement.    The present invention also teaches a method for solidifying wastes with this hardenable slurry, i.e. to proceed solidification by admixing the various radioactive or non-radioactive dry and wet wastes with the hardenable slurry, or by burying waste pellets with the slurry.  The solidified waste form thus obtained has a higher strength and the volume efficiency of the solidification is 2.5 to 10 times that of the conventional cement solidification. When applied to the solidification of low level radioactive wastes, the present method produces especially a tremendous economic efficiency.

Title: Absorbent article having flexible bending axes
Inventor: HSIEH TONG-HO J
IPC: A61F13/494
Filed: 1993-12-23
Abstract: An absorbent article, such as a sanitary napkin, is provided with first and second flexible bending axes separating front and rear portions of the article from a central portion. Each of the bending axes is created by a notch formed in the longitudinally extending sides of the article. A fluid pervious cover layer forms the body facing surface of the article. A transversely extending slit is formed in the portion of the cover within each of the notches. A fluid impervious barrier layer forms the garment facing surface of the article. A pleat is formed in the portion of the barrier extending between the edges of each of the slits. The notches, slits and pleats allow the front and rear portions of the article to freely bend upward into contact with the use's body and prevent lateral compression in the central portion of the article from being transmitted to the front and rear portions so as to undesirably increase the stiffness of the article in the longitudinal direction.

Title: Sewage incineration system
Inventor: WILKINS WILFRED J
IPC: F23G7/00
Filed: 1993-12-29
Abstract: Abstract of the Disclosure The invention is a sewage treatment system with a filter apparatus enclosed within a housing.          The filter operates to separate a liquid component from a solid component of the sewage.  It does so by having the sewage drop onto a diffuser.  The diffuser has a conical shape with its apex facing upward.  The diffuser breaks up the sewage and forces the sewage to flow against the filter walls.  The filter walls are liquid permeable which separates liquid from solid.   The solid component then falls to the bottom of the filter walls which has as its base an incinerator plate.  Hot air is then used to dry the sewage.  The incinerator plate heats to a combustion temperature and burns the sewage.  The ash resultant and the liquid component of the sewage is then removed from the chamber.

Filed: 1994-02-23
Abstract: A process and apparatus are disclosed for recovering a non-ferrous metal, preferably aluminum and aluminum alloys, in molten coherent form from a charge of material to be processed containing the metal. The charge is introduced into a sealable furnace which is then sealed. The charge is agitated. A control parameter indicative of conditions inside said furnace is monitored and compared to a pre-determined first condition for the parameter. A heat source is operated to heat the charge until the control parameter reaches the first condition. The operation of the heat source is then stopped. A controlled amount of oxidizing agent and an inert carrier is then introduced into the furnace. The control parameter is monitored and compared to a predetermined second condition for the parameter. The flow of the oxidizing agent and the carrier is controlled to maintain the control parameter at about the second condition. The molten metal is subsequently removed from the furnace.
