Abstract: A method and means for forcing a running web into contact with a chill roll is disclosed. The force is created by a second roller positioned with respect to the chill roll so as to create a nip, larger than the web width, through which the web passes. The second roller can be positioned directly above the chill roll, or slightly offset therefrom.

Abstract: A process of preparing iron chelates of amino and hydroxy carboxylic acids, comprising reacting an oxide of iron with an amino or hydroxy carboxylic acid and a base in the presence of ferrous ion or metallic iron as a catalyst. Additional base is added to the resulting chelant and oxidation may be carried out to convert any ferrous ion to ferric.

Abstract: A reflector for use in drying a substrate is disclosed, which houses infrared or ultraviolet lamps. The reflector is designed to limit the path of light from each lamp to mitigate interference from one lamp to the next. The reflector is cooled and the substrate is heated by convection.

Abstract: Infrared air float bar for use in floating and drying a continuous planar web of a material in a dryer. Direct radiated or reflected infrared electromagnetic energy from an infrared bulb in a removable air bar channel assembly accelerates drying, or evaporation of solvents, or curing of planar web material passing in proximity to the infrared air float bar either by infrared electromagnetic energy, or in combination with Coanda air flow. The infrared bulb is cooled by pressurized air passing through an interior portion of the removable air bar channel.

Abstract: A seal for a dryer having split enclosure drying hoods is disclosed. The hoods are retractable with respect to each other at at least one separation joint. A gasket capable of conforming to the contour of the joint is positioned in the joint. Preferably the gasket is of an inflatable type. The portions of the upper and lower hoods which terminate at the separation joint comprise a bellows, which provide a non-linear path for heat conduction and in which the gasket is positioned.

Abstract: A process of forming buoyant structures is disclosed, whereby a manifold is positioned in a buoyant structure mold so as to define a space therein that is devoid of buoyant bodies. The mold can then be filled with a resin/microsphere mix that meets minimal resistivity in the devoid space along the length of the manifold. A reduction in mold fill-time is achieved. The resulting buoyant bodies exhibit improved quality.

Abstract: A process for producing glycinonitrile under substantially adiabatic reaction conditions by reacting in a tubular reactor hydrogen cyanide, formaldehyde and ammonia. The excess ammonia is flashed off and the remaining solution volatiles are evaporated and condensed to product. The resulting glycinonitrile can be saponified to the alkali metal glycinate, from which glycine can be prepared.

Abstract: A directional diffusion nozzle air bar for utilizing an arrangement of holes to discharge air from a partial round member in the form of circular jets. The direction of discharge of the air is adjustable by a rotatable baffle rotatably mounted within the partial round member. The partial round member includes a plurality of holes along the length of the diffusion nozzle. The air bar provides the ability to adjust the angle of impingement of air on a web by alternating the direction of the circular jets without changing out the air bar. The air bar also provides the ability to profile the drying rate within a specific zone by directing the impingement air from each air bar.

Abstract: A rotatable slot nozzle air bar utilizing a rotatable baffle assembly to directionally discharge air through an attached slot. The direction of discharge of the air is adjustable by a rotatable baffle assembly rotatably mounted within a surrounding outer housing. The rotatable slot nozzle air bar provides the ability to adjust the direction of impingement air on a web by controlling the rotation of the rotatable baffle assembly in the outer housing without changing out the air bar. The rotatable slot nozzle air bar provides the ability to profile the drying rate within the zone by directing the impingement air from the slot nozzle. The rotatable slot nozzle assembly is rotated to change direction of impingement air, thus allowing for operation using direct impingement, induced diffusional flow or a varying combination of either.

Abstract: A new concept wall system is provided, wherein a moisture and vapor barrier is positioned in an enterior insulation finish system to provide thermal stability regardless of climatic variations. Specifically, a two part membrane of multiple cross-laminated layers of polyethylene film fully bonded to a layer of rubberized asphalt is placed between the substrate and insulation layers of the exterior insulation finish system.

Abstract: A process for preparing isophorone nitrile is disclosed, whereby isophorone is reacted with hydrogen cyanide in the presence of a quaternary ammonium catalyst. Remaining catalyst is removed by thermal destruction and nitrogen sparging. Residual cyanide is removed by acidification and nitrogen sparging.

Abstract: The separation and recovery of iminodiacetic acid and sodium sulfate decahydrate from sodium sulfate solutions such as the liquor generated in the production of iminodiacetic acids are disclosed. The separation is accomplished by adjusting the temperature of the sodium sulfate solutions to crystallize the iminodiacetic acid and sodium sulfate decahydrate. Nitrilotriacetic acid optionally can be isolated prior to the crystallization of the IDA and sodium sulfate decahydrate.

Abstract: A method and apparatus for determining particle size distribution of lightweight material such as shredded expanded polystyrene. An agitator cap assembly initially contains the material and agitates it to avoid clogging, etc. A plurality of sieves are stacked on a receptacle, and the material is driven from the agitator caps through the sieves. The amount of material retained on and passed through the sieves provides a measure of the particle size distribution.

Abstract: Glycine and sodium sulfate decahydrate are separated from a starting aqueous solution containing glycine, sodium sulfate, and impurities, by forming a slurry which is a solid mixture of glycine and sodium sulfate decahydrate, followed by separation of the mixed crystals.

Abstract: A method and apparatus for determining the particle size distribution of lightweight expanded polymers such as shredded expanded polystyrene is disclosed. The material to be sized is initially contained in a chamber which is in communication with gas supply. The gas supply urges the material through a plurality of sieves by means of a downward draft and agitation.

Abstract: A high electrical power-resistant radiowave absorbing body is disclosed comprising a carbon fiber fabric embedded in inorganic cement. The fabric can be woven or nonwoven. Carbon fiber fabrics of different densities can be used to develop a concentration gradient to enable wide frequency band absorption.

Abstract: A slurry distributor (S) for distributing a low viscosity fluid into a viscous, hydraulic slurry comprises a main conduit (1) located on a first axis .alpha. for conducting a flowing, viscous, hydraulic slurry towards an orifice (3). The distributor (S) has an air injector (5) defined by a stem (7) located on a second axis .beta.. The air injector (5) is for introducing air into the slurry to disperse it from the orifice (3). A second injector (9) located on a third axis .gamma. and intersecting the main conduit (1) is used to introduce a low viscosity liquid, preferably an accelerator, into the flowing slurry such that the low viscosity liquid impinges on the air injector stem (7) before dispersion. The distributor is especially useful with fireproofing compositions since it provides effective distribution of a viscous, hydraulic, cementitious slurry with an acidic accelerator.
