Title: Method to obtain disodium phosphate
Inventor: MULIARCHUK IVAN FEDOSIIOVYCH
Filed: 1999-02-26
Abstract: For obtaining anhydrous fodder disodium phosphate is proposed the solid-phase process of interaction sodium carbonate with diammonia phosphate within temperatures of 130-220º. The process is carried out without melt formations, without charge sticking on the apparatus, with whole isolation of ammonia and carbonic acid into gaseous phase. The upper limiting temperature is caused by formation of phosphates in form of tripolyphosphates. The method allows to use ammonia phosphates for producing the fodder disodium phosphate, these are got isolated from extractive phosphoric acid containing fluorine, because in the proposed solid-phase process fluorine can be isolated from the product in form of ammonia fluoride.

Title: Device for optically testing a transparent container by using two cameras and a light source
IPC: G01N21/21
Filed: 1999-05-13
Abstract: Apparatus for inspecting a container (14) for variations that affect commercial acceptability of the container that includes a light source (16) for directing diffuse polarized light energy through a container while the container is rotated about its axis. A first camera (24) is disposed to receive diffuse polarized light energy transmitted from the light source through a portion of the container, so that the first camera receives an image of the container portion in which opaque variations appear dark against an otherwise bright background. A second camera (28) receives light energy transmitted from the light source through substantially the same portion of the container, and includes a polarizer (32) at cross-orientation to the polarizer at the light source. The second camera receives a bright image of stress variations in the container, which alter polarization of the diffuse polarized light energy passing through the container, against an otherwise dark background. An image processor (41) is coupled to both of the cameras to scan associated images of the container portion viewed by the cameras for detecting and distinguishing between and among variations in the container as a function of a pixel by pixel comparison between the two images.

     SUBSTANCE: method of making industrial lot of super-finishing blocks of micro-powders by slip casting comprises steps of preparing slip, pouring it to molds, dehydrating, extracting blank out of molds, souring, drying, performing high-temperature firing and testing rigidity of blank. Values of real shrinkage of blank sides are determined with use of reference test-sampler. Molds whose inner size and height of pouring slip into them are determined while taking into account said shrinkage values if it is necessary to make industrial lot of super-finishing blocks. In order to make test sampler, mold whose inner size and height of poured slip are determined by summing lateral dimensions of ready super-finishing block and values of expected shrinkage for time period from dehydrating slip until firing test sampler. Real shrinkage values are determined by subtracting from inner lateral dimensions of mold of test-sampler and height of slip poured to it, real respective lateral dimensions of test-sampler measured after firing it. Inner size of molds and height of slip poured to them at making industrial lot of super-finishing blocks are calculated by summing lateral dimensions of ready block and values of real shrinkage of respective sides of test-sampler. In order to make blocks with allowances for mechanical working, dimensions of ready block, values of real shrinkage of respective sides of test sampler and values of allowances for mechanical working are summed. Protrusion on end of blanks formed because of concrete construction of used mold is removed by cutting it by means of knife at souring blanks or it is removed at mechanically working fired blank. In order to perform the method, special construction (given in description of invention) of mold is used. 
     EFFECT: reduced consumption of abrasive materials, electric energy, shortened time period for working blanks.
