Abstract: A B S T R A C T        Synthetic yarn and yarn-like structures are formed by the method of treating separate multi-filament strands of thermoplastics material so that at least one has a shrinkage ratio higher than normal at an elevated temperature.  The strands are intermingled in a gas stream with formation of loops on the strands after which they are subjected to a twisting force which imparts a random form of twist on the inter-mingled formation followed by a heating operation to cause them to shrink differentially while being held until shrinkage ceases so that interlocking bud-like projections form on the filaments. Apparatus for performing the method includes yarn drawing means, intermingling means comprising a jet device incorporating intersecting passages for the strands and for a gas under pressure, means arranged to apply a twisting force to the intermingled filaments,feeding means and heating and cooling means for the intermingled yarn incorporating twist downstream from the jet device, also means for holding the yarn to a predetermined length while it is being heated and cooled.

The oxide thus obtained is a form having a comparatively low refractive index.  By heating the product, after providing the film, rapidly to a temperature of above 700°C, preferably above 1,000°C, keeping it at this temperature for some time and then rapidly cooling it again, a modification having a higher refrac-tive index (for example, for TiO2 rutile) is obtained.

Abstract: ABSTRACT OF DISCLOSURE        This high-pressure, high-temperature anhydrous process prepares melamine from urea.  It is a primary ob-ject of the present invention to provide a highly energy-efficient and improved continuous process for the produc-tion of melamine from urea which utilizes a simplified process to produce and recover a high-grade (96 to 99.5% purity) melamine as a dry powder directly from liquid melamine melt.  Molten urea is supplied to a reactor main-tained at high temperature (700 to 800°F.) and high pres-sure (1700 to 2200 psig) whereby melamine, CO2, and NH3 are formed.  The reactor effluent stream containing liquid melamine, CO2, and NH3 is transferred to a gas separator where CO2 and NH3 containing melamine are separated and cycled to a scrubber unit for scrubbing with molten urea reactant to remove the melamine before transfer of the CO2 and NH3 gases at high pressure to an adjacent urea plant for utilization in producing urea.  The melamine liquid product is transferred from the gas separator to a col-lecting tank maintained at a pressure of less than about 615 psig and from about 120 to 260°F. where the liquid melamine is immediately contacted with, or quenched with a liquid, preferably liquid ammonia.  The melamine separates as a dry powder which requires no further processing, hav-ing a purity in the range of 96 to 99.5%, useful in appli-cations including fertilizer and resin manufacture.  This process is highly cost efficient.
