Title: Improvements in or relating to the drying of granules of amorphous polyethylene terephthalate
IPC: B29B13/06
Filed: 1962-07-02
Abstract: Amorphous polyethylene terephthalate granules, containing water, are dried in a two stage continuous drying process using a hot inert gas as the drying agent.  The granules are partially crystallized in a bed of the granules fluidized by the hot inert gas at a temperature of at least 110 DEG C. in the first stage, so that they neither soften when heated in air above 70 DEG C. nor stick to one another. The feed to the fluidized bed is mixed with at least 50% by weight of pre-crystallized granules to prevent any agglomeration of the granules during this first stage.  The second stage of the process comprises drying the granules leaving the fluidized bed to a moisture content of less than 0.01% by weight, using standard continuous direct drying apparatus, the drying gas used having a temperature above 80 DEG C., preferably in the range of 80-180 DEG C. Inert gases specified are carbon dioxide, nitrogen or air.ALSO:A continuous process for the drying of amorphous granules of polyethylene terephthalate containing water, comprises a first stage wherein the granules are partially crystallized in a fluidized bed by means of a hot inert gas at a temperature of at least 110  DEG C., and a second stage wherein the granules are further dried at a temperature above 80  DEG C. by means of a hot inert gas until they contain less than 0,01% by weight of moisture.  The fluidized bed of the first stage contains at least 50% by weight of partially or wholly crystallized granules, and the fluidizing inert gas is supplied at such a rate that the ratio of the height of the layer of granules when fluidized to the height of the layer of granules when non-fluidized is at least 2.  The expression "partially crystallized granule" indicates that the granule is crystallized to such an extent that it neither softens at an air temperature above 70  DEG C. nor sticks to other granules. The second stage of the process may be carried out by passing the granules on a conveyer belt through a drying chamber against a current of a hot inert gas, or by transporting the granules counter-current to the hot inert gas in an enclosed screw conveyer. The temperature of the hot inert gas used in the second stage is maintained in the range of 80-180  DEG C.  Inert gases specified are carbon dioxide, nitrogen or air.

Abstract: 533,381. Humidity measuring devices. NEGRETTI, H. N., NEGRETTI, P. E., and GREGORY, H. SPENCER-. Sept. 8, 1939, No. 25462. [Class 37] A humidity measuring device comprises hygroscopic material intimately incorporated in a piece of textile cellulosic material such as cotton fabric which is interposed between electrodes so that its resistance can be measured. A strip of muslin 1 is clamped at its ends in nickel gauge electrodes 2, 3 and is then boiled for about ten minutes in a 5 per cent. solution of calcium chloride, and dried in a horizontal position so that the hygroscopic substance is deposited uniformly. The strip is then mounted between end rings 4, 5 spaced apart by rods 6. The electrodes 2, 3 are connected to terminals 7 by connecting elements 8 welded to the electrodes. A spring 9 holds the muslin 1 taut. The whole is enclosed in a perforated cylindrical container which is either suspended or supported by a bracket in a room or other space where the humidity is to be determined. The container may have a conical nose so that it may be inserted into a body of material whose moisture content is to be determined. The resistance of the impregnated strip 1 may be measured by connecting it in an A.C. circuit in series with an ammeter. A D.C. measuring instrument responsive to changes in current in the A.C. circuit may be used, e.g. by employing a converter. Alternatively, the resistance constituted by the hygroscopic material may form one arm of a Wheatstone bridge, in which case a second arm may be formed by a similar hygroscopic resistance exposed to the same temperature conditions but not to variable humidity. According to the Provisional Specification, the strip of muslin may be replaced by a thread of cotton for use in restricted areas.
