Title: Method of coding a sampled speech signal vector
Inventor: MINDE TOR B
IPC: G10L25/06
Filed: 1991-07-15
Abstract: The invention relates to a method of coding a sampled speech signal vector by selecting an optimal excitation vector in an adaptive code book (100). This optimal excitation vector is obtained by maximizing the energy normalized square of the cross correlation between the convolution (102) of the excitation vectors with the impulse response (h w (n)) of a linear filter and the speech signal vector. Before the convolution the vectors of the code book (100) are block normalized (200) with respect to the vector component largest in magnitude. In a similar way the speech signal vector (s(n)) is block normalized (202) with respect to its component largest in magnitude. Calculated values for the squared cross correlation C I and the energy E I and corresponding values C N, E M for the best excitation vector so far are divided into a mantissa and a scaling factor with a limited number of scaling levels. The number of levels can be different for squared cross correlation and energy. During the calculation of the products C I × E M and E I × C M, which are used for determining the optimal excitation vector, the respective mantissas are multiplied and a separate scaling factor calculation is performed.

Abstract: LINEAR VISCOELASTIC AQUEOUS LIQUID AUTOMATIC DISHWASHER DETERGENT COMPOSITION                 ABSTRACT OF THE DISCLOSURE    Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability in exposed daylight, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener.  Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability.  Control of incorporated air bubble functions to provide the product with a bulk density of 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase.  A polymeric chelating agent in the composition improves physical stability.

IPC: B64F1/36
Filed: 1992-07-20
Abstract: ABSTRACT OF THE DISCLOSURE    To carry conditioned air from a conditioned air source to a receiving body an apparatus, or duct system, is required.          In this invention the duct that will carry the conditioned air from a conditioned air source to the receiving body will be in one  continuous  length.    Said  duct will  be  enclosed  in insulation and together the duct and insulation are framed within a plywood box.  All sides of the box are also in one continuous length.  Metal, preferably steel, is wrapped around the box and fastened to the bottom of the box.  This metal seals the duct system and makes it weatherproof and fireproof.          The duct system will be made in varying lengths and will be capable of hooking together in series.  This invention can have a dolly at either end thus making it portable, or it can be mounted onto blocks or concrete making it fixed.

Abstract: A method of brewing a malt beverage having a low alcohol content is disclosed.   A malt and cereal  infusion having an extract content below about 14% is prepared, and boiled to obtain a wort.  A predetermined quantity of hops are then added to said wort, which is then aerated to an oxygen content of 15 - 35 µg per litre.   The wort is pitched with a yeast slurry to provide a cell count of about 80 to about 180 million yeast cells per ml and fermented at a temperature of about 3°C to about 10°C for 1 to 40 hours.  The yeast is then removed from the fermented wort, and the resulting brew  is  filtered, and electrolyzed with a copper electrode to remove H2S.  The alcohol concentration of the brew is then adjusted with carbonated water to a preselected level, and then the resultant brew is aged for at least 24 hours.
Patent CA-2078464-A1 (CA)
Title: Improved vent for enclosures
Inventor: STEELE EDWARD A
IPC: F24F13/08
Filed: 1992-09-17
Abstract: A vent arrangement is provided for enclosures that prevents the entry of water into the enclosure and that also prevents the penetration of a pry bar or probe wire.  The vent arrange-ment includes a first predetermined pattern of openings of predetermined shape and dimensions provided at the exterior wall of the enclosure. The dimensions of the openings and the spacing between the openings are determined relative to the pry bar and the material in which openings are formed, such that the pry bar cannot fully enter the openings and such that the portion of the pry bar that can be applied to the openings does not cause any substantial deformation of the material surrounding the openings that could permit widening of the openings so as to allow full entry of the tip of the pry bar. In a preferred embodiment, to permit the maximum percentage area of openings within the pattern of openings while achieving the desired tamper-resistance characteristics, the first predetermined pattern of openings includes staggered rows of openings such that the openings of adjacent rows are not aligned. The vent arrangement also includes a baffle plate spaced behind the predetermined pattern of openings. The baffle plate includes facilities to freely pass air, but prevents the ingress of any water that may enter through the first predetermined pattern of openings. The baffle plate is arranged to direct all such water out through the bottom of the first predetermined pattern of openings. In a preferred arrangement, the vent arrangement also includes facilities to prevent the ingress of a probe wire beyond the baffle plate and into the enclosure even if the probe wire passes into the venting arrangement beyond the first predetermined pattern of openings. In a specific embodiment, this is achieved by the provision of a double layer of wire-mesh screen or the like disposed within the vent arrangement between the first predetermined pattern of openings and the baffle plate. The double layer of wire-mesh screen is arranged in a closed path in the shape of a cage or the like.

Title: Ion chromatography system using electrochemical suppression and detector effluent recycle
Inventor: STILLIAN JOHN R
IPC: G01N30/64
Filed: 1993-01-18
Abstract: A method of streamlining and lowering the cost of operation of ion chromatography as well as improving detection limits is disclosed. The apparatus includes chromatographic separating means through which a sample is eluted in an fluent solution including an electrolyte. The apparatus includes suppressor means having a chromatography effluent compartment means separated from a detector effluent compartment means by an ion exchange membrane, forming a chromatography effluent flow channel and a detector effluent channel, respectively. Electrode means are disposed in communication with both flow channels for passing an electric current transverse to the solution that is passing through them. The chromatography effluent flows through the chromatography effluent flow channel of the suppressor and through detector means which detects resolved ionic species therein. The effluent from the detector means is then recycled through the detector effluent flow channel and forms a sump for electrolyte ions passing across the chromatography effluent as well as supplying the water for the electrolysis reaction generating acid (or base) for suppression.
