Abstract: A vessel has an annular upstanding wall and a bottom that together define an inner shell adapted to hold a vessel media. A baffle system is disposed in an interior of the inner shell and comprises a plurality of baffle portions each being generally an elongate planar member with a length edge and a width edge, and a tab projecting from the length edge. Each of the baffle portions is mounted to the upstanding wall at their respective tab with one of the baffle portion above the second baffle portion and a space therebetween.

Abstract: A heat exchanger tube in a heat exchanger for an ice making machine includes a bimetallic heat exchanger tube to improve capacity and wear characteristics of the heat exchanger. The heat exchanger tube has an outer portion with a first material composition and an inner portion with a second material composition where the first material composition is different from the second material composition. The first material composition is compatible with the refrigerants used in the heat exchanger unit of the ice making machine. The second material composition is compatible with the feed solution being chilled in the heat exchanger tube.

Abstract: A machine for freezing or chilling a liquid continuously to produce a slurry of the liquid and frozen crystals feeds the liquid into a vertically oriented heat transfer tube at its upper end. A refrigerant flow at the outer tube surface evaporates in a vapor/foam stream causing the liquid to freeze at the inner tube surface. A whip rod, preferably one that is free-standing, revolves over the inner surface to dislodge the frozen crystals mechanically and to distribute the liquid. An additive to the liquid such as ethylene glycol (in water) aids the dislodging. In one form, a mechanical flow guide surrounding the outer surface produces a thin, high velocity upward flow of the boiling refrigerant to increase the heat transfer. An orbital drive propels the whip rod. In one form the orbital drive includes a pair of horizontal plates coupled between the whip rod and at least one eccentric crank.

Abstract: An orbital evaporator has a vertical heat transfer tube or tubes mounted in a container driven in an orbital motion. A stiff whip rod is freely movable within the tube. Its lower end rests on a horizontal plate. The orbital motion causes the rod to roll over the interior surface of the tube to distribute the liquid in a thin film and to control fouling. A set of fins is mounted on the exterior of the tube to collect and channel the condensate to improve heat transfer through the tube. The fins are preferably longitudinal and the whip rod is preferably hydrophobic. Operating the evaporator with boiling temperatures substantially below 100.degree. C. in combination with the fins and a rolling whip rod allows operation as a desalinization unit for an indefinite period of time with a high total heat transfer coefficient. The evaporator preferably also includes a degasser to control the formation of a gas barrier at the exterior surface of the tube.

Abstract: Photosensitive compositions containing nitrate ester chain polymers, such as nitrocellulose, molecularly intimately admixed with at least one compound having a free basic amine group, preferably a primary amine group, directly attached to an aromatic ring carbon. On suitable exposure to ultraviolet light, such compositions will print out a useful image directly, or, should a much lesser light exposure be preferred, they can be developed and fixed to an image intensified to useful strength by either heat alone, for amines that are sufficiently volatile at ingredient reaction temperatures, or by solvent selective removal of ingredients from unexposed areas, and subsequently intensified either by heat or overall ultraviolet exposure. Exposed areas of such compositions are more resistant both to volatilization of the amines and to solvent removal than the non-exposed areas. High optical density is attainable using very thin coatings, permitting high resolution grainless images.

Abstract: The self-aligning characteristics of surface-active molecules are used to provide a multiply-coupled thin film surface coating on a substrate, comprising an outermost layer of normally fluid, flexible backbone chain polymer units of at least about 30 atoms in length, the ends of which are attached by chemical bonds to a relatively highly polar second layer of atoms serving to anchor the relatively fluid outer surface layer polymer chains to the surface of the substrate.

Abstract: Photosensitive compositions containing nitrate ester chain polymers, such as nitrocellulose, molecularly intimately admixed with at least one compound having a free basic amine group, preferably a primary amine group, directly attached to an aromatic ring carbon and also containing an organic acid. On suitable exposure to ultraviolet light, such compositions will print out a useful image directly, or, should a much lesser light exposure be preferred, they can be developed and fixed to an image intensified to useful strength by either heat alone, for amines that are sufficiently volatile at ingredient reaction temperatures, or by solvent selective removal of ingredients from unexposed areas, and subsequently intensified either by heat or overall ultraviolet exposure. Exposed areas of such compositions are more resistant both to volatilization of the amines and to solvent removal than the non-exposed areas.
