Title: Ultradense and more soluble and bioavailable preparation of calcium citrate
Inventor: PAK CHARLES Y C
IPC: A23L1/304
Filed: 1987-03-13
Granted: 1991-03-12
Abstract: ABSTRACT OF THE DISCLOSURE      A calcium citrate composition having a bulk density greater than about 1.1 g/cc.  Citric acid and a calcium compound are mixed to produce a mixture having a calcium compound/citric acid molar ratio of about 1.5.  A hydrated mixture percent is produced by agitatively adding water to the mixture, although when desired the calcium compound, citric acid and water may be mixed in one step.  The hydrated mixture is blended to facilitate the reaction of citric acid with the calcium compound and to form a granulated mass primarily consisting of granules with diameters between about 1/64 inch (39.7 mm) and about 1/16 inch (159.0 mm).  The granulated mass is then dried to a moisture content of between about 10 weight percent and about 13 weight percent to produce a calcium citrate composition having a bulk density greater than about 1.1 g/cc. For calcium citrate tablets this calcium citrate composition is formed into a tableting composition by subjoining one or more tableting binders.  The tableting composition is then fed through a multiple-station tablet press to form high density calcium citrate tablets. The high  density  calcium  citrate  tablets  are  greater than about 15 weight percent calcium and have a calcium/ citrate molar ratio of about 1.5.  Such tablets charac-teristically have a density greater than about 1.5 g/cc and may, for aesthetic or other purposes, be coated with mixtures comprising substances such as sugar, polyvinyl-pyrrolidone, calcium carbonate and titanium dioxide.

Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE    From a speech signal, spectrum information as a plurality of line spectrum data, pitch position data and amplitude data are extracted.  Each of the sinusoidal wave signals of different frequencies is allotted to the predetermined line spectrum data.  The frequency of the sinusoidal wave signal is changed with the pitch position being the boundary.  The plurality of sinusoidal wave signals are added and the added result is modulated by the amplitude data to transmit the modulated signal as the transmission data.  The line spectrum data, the pitch position data and amplitude data are extracted from the modulated signal.  The replica of the speech is produced on the basis of these extracted data.

Title: Method and apparatus for detecting the peak of an analog signal
Inventor: MORRIS STEVEN A
IPC: G01V1/26
Filed: 1988-03-18
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for processing a signal generated by a borehole scanning system of the type in which periodic electrical firing pulses initiate a plur-ality of corresponding acoustic energy pulses which are transmitted from the central portion of the borehole toward the borehole wall in a plurality of radial direc-tions and at a plurality of different depths, thereby gen-erating reflected acoustic pulses which are detected and converted to electrical pulses.  The electrical pulse is periodically sampled with each sample level being con-verted to a digital number.  Each new digital sample number is compared to the maximum of the preceding digital sample numbers and stored if the new digital sample number exceeds that maximum.  A counter initiates counting in response to the firing pulse preceding the sample elec-trical pulse.  Upon detection of the peak of the elec-trical pulse, the counter count is stored, thus yielding both the peak value of the electrical pulse and the elapsed time between the preceding firing pulse and peak of the electrical pulse.

Abstract: APPARATUS AND METHOD FOR THE DEEP CRYOGENIC           TREATMENT OF MATERIALS            Abstract of the Disclosure Apparatus and method for the ultralow temperature processing of metallic, carbide, ceramic and plastic parts and items to materially increase their wear, abrasion, erosion and corrosion resistivity, stabilize their strength characteristics, improve their machinability and provide stress relief. An insulated box-like treatment chamber is disclosed which includes a perforated platform extending parallel to and spaced above the bottom of the chamber.  Parts and items to be treated are supported on the platform and cryogenic liquid is introduced into the chamber below the platform in accordance with a time-temperature program which reduces the temperature of the parts and items in stages to -195°C (-320°F) by initial cooling of the parts and items by evaporating vapors from the cryogenic liquid pool in the space below the platform and thereafter by partial or substantial submersion of the parts and items in the cryogenic liquid.  After a soak period at the -195°C (-320°F) temperature level, the temperature of the parts and items in the treatment chamber is raised to ambient by controlled evaporation of the cryogenic liquid therein.  Temperature and liquid level monitoring devices are mounted in the treatment chamber and information derived therefrom is utilized by a process controller to direct the supply of cryogenic liquid to the treatment chamber in accordance with the desired temperature descent and ascent profiles for the weight of the parts within the chamber.

Abstract: METHOD OF AND APPARATUS FOR CONTROLLING APPLICATION OF GLUE TO DEFINED AREAS            Abstract of the Disclosure Apparatus for applying adhesive onto flutes of single facers of corrugated media, so that the single facers may be adhered together and to a facing to form a composite web, comprises a plurality of adhesive applicator rolls, each for applying adhesive to the flutes of an associated one of the single facers.  The actual speed of travel of the single facers passing across the applicator roll peripheries is sensed, and the rate of notation of each roll is independently and accurately controlled, in accordance with the sensed speed, to apply a desired amount of adhesive onto selected areas of the flutes.  The independent accurate control over applicator roll speeds enables minimum amounts of adhesive to be applied onto the flutes of the individual single spacers, as determined by their configurations and consistencies, while still ensuring proper adhesion of the single facers one to the other and to the facing.  Applying minimum amounts of adhesive onto the flutes reduces both the amount of adhesive required and moisture added to the single facers, so less heat is required to set the adhesive.  In addition, minimizing moisture added to the single facers substantially eliminates warping of the composite web and "ribbing" on its outer surfaces, so the surfaces are very smooth and very high quality printing and graphics may be applied onto the surfaces.
