Title: Combination direct and indirect closed ciruit evaporative heat exchanger with blow-through fan
Inventor: KORENIC BRANISLAV
IPC: F28C1/14
Filed: 1996-03-22
Abstract: A heat exchange apparatus (10) which can be used as an evaporative condenser, fluid cooler or wet-air cooler, is provided with a direct evaporative heat exchange section (90) overlying an indirect evaporative heat exchange section (50). An air entry zone (120) common to both heat exchange sections (50;90) receives an air stream blown into this zone by at least one fan (24), thereby pressurizing the plenum such that the air stream is forced to split and enter each section (50;90) while inside the apparatus. This eliminates the need for separate air entries, thus condensing the size and cost of the apparatus, while increasing heat exchange capacity. A countercurrent air flow pattern through the direct section (90) provides a uniformly cooled evaporative liquid for use in the indirect section (50). The evaporative liquid flow is parallel to the air stream provided in the indirect section. A process fluid inside the circuits of the indirect section (50) can accept or reject heat from the evaporative liquid received from the direct section (90), with a part of the heat being transferred into the indirect section air stream in sensible and latent form, thus increasing or decreasing the enthalpy of the air stream. The remaining heat can be either stored or released from the evaporative liquid to increase or decrease its temperature. The evaporative liquid is collected in a sump (30) and then pumped upwardly for re-distribution across the direct evaporative heat exchange section (90). <IMAGE>

Date Dec. 31, 1997A coating system comprised of a resin component, a hardening component and additives. The resin component contains (meth)acrylic double bonds and at least two reactive hydroxyl groups, and the hardening component is comprised of a multifunctional, at least bifunctional isocyanate. The proportions of resin and hardening component in the coating system are stoichiometric. The coating system is suitable for producing laminated sheets with a surface layer of progressively hardening polyurethane acrylate. During a first hardening stage, the free hydroxyl groups of the resin component cross-link with the isocyanate groups of the hardening component, forming a urethane acrylate prepolymer which contains (meth)acrylic double bonds. In the second hardening state, the (meth)acrylic double bonds continue to cross-link, forming the urethane acrylic polymer coating of the sheet surface. The progressive cross-linking reaction may be controlled by altering the reaction parameters, such as pressure, temperature, choice of additives and chemical constitution of the hardening component.

Abstract: An ear tag for animal identification is a one-piece plastics moulding with a female end 1 having an opening 12 and a male end 2 having a barbed spike 22, connected by a flexible link 3. It secures through an animal's ear and presents an exterior printable surface 32 to carry a visual identification code.
