Abstract: ABSTRACT     AN OVEN      An oven comprises at least two doors and a filter arrangement (1), through which the air inside the oven may circulate in a closed circuit by means of a circulator (2), said closed circuit optionally including means (3) for adjusting the temperature of the air. The filter arrange-ment (1) comprises a frame loosely secured to a resilient airtight trumpet- or tube-like suspension arrangement (5).    This suspension arrangement is in turn secured to the rim of a channel permitting passage of the circulating air, whereby the major portion of said rim may be formed by the oven shell (7). In this manner the frame of the filter may operate and expand relative to the oven shell (7) without causing the channel to leak. A particular shaft seal fur-thermore implies that the driving motor of the circulator may be situated outside the oven without permitting pollut-ed air to penetrate at the inlet opening of the rotating shaft.

Abstract: ABSTRACT OF THE DISCLOSURE    A device for automatic translation of natural language words into corresponding visual images has an addressable video disc memory storing a large number of images, an image dictionary memory for storing the video disc addresses for sets of images for respective natural language words along with information controlling the selection and display of the respective images, and a computer for addressing the image dictionary memory and interpreting the selection and display information.  The translation device is advantageously used in an audio-visual presentation system which also includes a speech synthesizer and a multiple image display synchronized to the pronunciation or the speech synthesizer.          Preferably, the selection of images is responsive to viewer preferences and the context of the translated words, and redundancy of image presentation is eliminated by random or indexed selection.

Abstract: ASPHALT COKING METHOD     ABSTRACT OF THE DISCLOSURE           A delayed coking process and a solvent deasphalt-ing process are combined so that an asphalt mix of asphalt and solvent from the solvent deasphalting process is sent as feedstock to the delayed coking process to form coke and intermediate hydrocarbon vapor and liquid products.  The vaporization of the solvent in a delayed coker heater assists the flow of the asphalt mix through the heater, and a por-tion of the asphalt mix is directed to a delayed coking fractionator so that the flow of solvent through the delayed coking heater can be adjusted by varying the relative amounts of asphalt mix sent to the delayed coker heater and to the fractionator.  A deasphalted oil mix of deasphalted oil and solvent from the solvent deasphalting process is heated by hotter fluid products from a fractionator in the delayed coking process, and makeup solvent to a solvent deasphalting section is heated by vapors in the fractionator overhead.     The solvent is recovered from the deasphalted oil mix to yield deasphalted oil, which is stripped in the same vessel as products from the fractionator of the delayed coking process.  Condensation of the vapors from the fractionator overhead produces sufficient lean oil that a separate lean oil still may not be required for the economic recovery of coker liquefied petroleum gases.  Solvent may be recovered from the lean oil and naphtha products to supple-ment the makeup solvent.

Abstract: Abstract of the Disclosure A new stable derivative of ascorbic acid, ascorbate 2-polyphosphate,  Is disclosed,  together with a high-yield method of synthesis thereof.  The method preferably includes steps of reacting an ascorbic acid such as L-ascorbic acid or a deriva-tive thereof such as 5,6-0-isopropylidene-L-ascor-bic acid with salts of metaphosphoric acid in an aqueous system and in the presence of sufficient base to maintain the pH of the reaction mixture at a level of at least above 9 to obtain 2-polyphos-phorylation of the ascorbic acid.  In particularly preferred forms, 1 M L-ascorbic acid is reacted in water with 1.5-3 equivalents of sodium or potassium trimetaphosphate at a temperature of 25-55°C, and an alkali metal hydroxide such as potassium hydrox-ide is intermittently added to the reaction mixture as needed over a 1-10hr. reaction  period to main-tain the pH thereof at a level of about 10.5-12 during the entire reaction.   After neutralization the reaction mixture contains no noxious or toxic materials, and the entire mixture may be added to food or feed.   Pure salts of ascorbate 2-triphos-phate can be isolated readily using conventional chromatographic techniques.  It has also been found that the compounds of the invention are more diffi-cult to oxidize, and release ascorbic acid and are more  slowly  hydrolyzed  than  the  monophosphate derivative of ascorbic acid.
