Abstract: The method for cooling a hot web by passing it across a rotating thermally conductive chill roller having a circulating coolant therein. In accordance with this invention, one introduces as a coolant to the chill roller a liquid refrigerant at a temperature and pressure permitting the refrigerant to exist in liquid form, the temperature being also above the dew point of the ambient atmosphere. Likewise, the boiling point of the refrigerant at the desired temperature and pressure is low enough to cause heat to be absorbed by the chill roller substantially by vaporization of the liquid refrigerant. One then withdraws refrigerant vapor from the chill roller, and typically refrigerates it to reform the liquid phase for return to the chill roller. Typically, chlorofluorocarbon refrigerants are preferred.

Abstract: A chill roll for cooling a web, such as in the printing industry, where a uniform temperature across the chill roll is maintained. Journals support an outer roll assembly and an inner roll assembly. The inner roll assembly is bearing mounted on the inner ends of opposing journals and the outer roll is rotated about the inner roll, which is weighted to free-wheel about the bearings to minimize rotary motion. Coolant is introduced through the journal on one end and into a center tube, where the coolant uniformly flows in an annular space between the rolls and along the length of the inner and outer roll assemblies to circumferentially traverse between the rotating and stationary outer and inner rolls. This coolant flow provides enhanced heat transfer from the outer rotating chill roll to the circulating coolant. Heated coolant collects and returns through a center tube, and exhausts through the center tube and out through the journal.

Abstract: The object of the invention is a method of arranging the cooling in a compactor equipped with at least one roller drum, in which the motor and/or other equipment, for example the hydraulic system, has forced circulation water cooling or water cooled closed forced circulation air cooling. The intention of the invention is to remove the problem of the dirtying of the radiator cells that exists in present cooling systems.In the method in accordance with the invention the cooling water is circulated through the roller and is brought in thermal contact with the outer covering of the roller in order to transfer the heat from this to the surrounding air and to the ground. Further, a heat exchanger through which coolant flows may also be placed inside the roller, immersed in a second volume of cooling fluid. The heat exchanger may be placed into direct physical contact with the outer cover of the roller.

Abstract: The invention is a fluid heated drum especially well adapted for use with a drum press in which high press roll nip loading and high heat flux to a pressed web are both encountered. A press of this type is disclosed in detail. However, the drum is more broadly useful in any application combining heavy mechanical drum loading and high heat flux through the drum surface. The drum is constructed with a thin outer shell spaced radially apart from an inner cylindrical body. Radial supports provide load bearing connections between the two. The annulus between the shell and inner body may be arranged in various patterns as a conduit for the flow of heating fluid. By using a thin outer shell which does not have to sustain high bending stresses a high rate of heat transfer is permitted. The outer shell may be made of copper or other high thermal flux but lower strength metal to obtain additional heat transfer advantages.

Abstract: A rotary kiln is formed by a helical tube secured inside a cylindrical shell, and fitted with flow spoiler baffles between each turn of the helical tube. Inside the helical tube, one solid particle stream flows uphill in the manner of the classical Archimedes screw. Another stream of particles is tumbled by the flow spoiler baffles and flows under gravity downhill through the center of the helical tube, tumbling over the successive convolutions of the helical tube. This downhill flow occurs because the particles collide with the interflute spoiler baffles, tumble and fall off the helical flutes, thus causing the countercurrent flow. A wide range of surface-to-volume ratios of, and heat transfer through, the helical tube may be achieved by a proper design of the relative width of the tube. This helical tube in a drum device provides heat transfer for a varied number of process applications, such as oil shale or tar sands retorting.

Abstract: A vacuum evaporation apparatus for depositing an evaporant as a thin film on a substrate comprises a sealed container including a substrate support for mounting thereon the substrate. A heat medium such as of diphenyl, for example, is filled in the substrate support. The heat medium in the substrate support is supplied with heat by a heater.

The vapor gas in the low-temperature region is supersaturated and turned into the heat medium liquid. The heat energy born as latent heat by the vapor gas is given off to heat the substrate support uniformly. With this thermosiphon action, the substrate can be heated through the substrate support so as to have a uniform overall temperature distribution for forming a uniformly deposited thin film on the substrate surface.

Abstract: In accordance with the invention an apparatus and method are provided for curing resin-coated particles on a heated rotating surface. A single layer coating of uncured resin-coated particles is fed to the heated rotating surface. As the surface continues to rotate the uncured resin-coated particles become tacky and adhere to the rotating surface. The tack adhesion prevents the pull of gravity from separating the particles from the surface as rotation continues. Proper curing of the particles occurs on the heated rotating surface before one complete revolution is made by the surface. Cured particles are removed by a stationary scraper blade edge which rides the rotating surface and wedges between the adhering particles and the surface as the surface rotates past the edge.
