Abstract: A portable batch pasteurizer for pasteurization or other heat treatment of contained fluids for consumption by animals or humans provides a heat transfer coil through which hot or cold fluids are pumped to heat or cool the fluid in which it is immersed. An impeller circulates the fluid in which the fluid is contained to ensure even heating or cooling.

Abstract: Protective hats having a crown and broad brim provide protection from the sun and by surfaces reflecting light and/or radar waves provide distress signalling means. The hats can be colored international orange for enhancing their usefulness as a distress signal. Due to stiffening means such as a springy hoop of suitable material contained within the peripheral binder of the hat's brim, it can be easily folded into a small package for storage or carrying on the person.

Abstract: Inflatable radar reflectors comprising three mutually orthogonal radar reflective planes incorporated within the structure thereof can take the form of a teardrop, a cylindrical drogue or a set of three intersecting discs. A preferred embodiment includes three inflatable hollow toruses of flexible material which mutually intersect in a manner such that their planes are mutually orthogonal and each intersection provides a passage for air to pass between the intersecting sections thereof, inflation means for filling the three toruses simulataneously and collapsible circular panels of radar-reflective material covering each torus so that they form mutually orthogonal radar reflective planes. The preferred embodiment can be encased in a radar permeable balloon.

Abstract: The present invention relates generally to aqueous coating compositions comprising a resin component including a functional group-containing crosslinkable resin and, optionally, a curing/crosslinking agent for functional groups of the crosslinkable resin. More specifically, the resin component includes, at least in part, a special anionically or anionically/non-ionically stabilized functional group-containing crosslinkable resin which can function as either the primary crosslinkable resin (self-emulsifying system) or as a reactive emulsifier for other lipophilic crosslinkable resins (stabilized system).

Abstract: Distress signal kits comprise a parafoil for carrying aloft various emergency or distress signals such as radar reflective materials, lights, flares, distress flags or smoke signals. Preferably the parafoil itself is colored International orange and contains a U.S. Coast Guard-approved distress signal (BLACK SQUARE AND CIRCLE) on both top and bottom surfaces. The parafoil can be used to raise a spinnaker sail attached to a vessel or swimmer. The spinnaker can also carry radar reflective components and/or distress flags, and can be fitted for other survival uses.

Abstract: Systems for reinforcing various waterfront properties such as riverbanks, lake shores and beaches of oceans, bays and the like to protect them from erosion and encourage accretion of beach sand and gravel are disclosed. Improved seawalls and the like can be built from L-shaped members having a vertical wall portion, a horizontal footer, a vertical key protruding below the footer and an angular splash plate protruding from the wall opposite the footer. Systems based upon such seawalls may further comprise groins perpendicular thereto which are built from inverted "T"-shaped members, and optionally rows of such inverted "T" members parallel to the seawall as well. Further, erosion of the bank above the seawall and/or the beach below same may be reduced by partially covering them with water-permeable concrete mats. One or more groins extending perpendicular from the seawall may preferably be fabricated of inverted "Double T" members and adapted to support a pier.

Abstract: Twin-hulled boats such as SWATH (Small Waterplane Area Twin Hull) boats are designed and built to be so dimensioned as to fit transportably and removably atop the sidewalls of the open bodies or beds of various vehicles such as pickup trucks, trailers and the like. The horizontal deck and substantially solid hulls or struts of the boat provide a cover, closure or "cap" for the truck bed while installed. Such boats can be easily removed from the truck bed for use or storage. In one embodiment, the twin hulls have a cross section which is a hybrid of the relatively wide, shallow hulls of a catamaran and the narrow, deep struts attached to the lower flotation hulls of a SWATH boat. In the SWATH embodiment, the flotation hulls can be removed for separate transport, the struts themselves being secured atop the sidewalls, or the hulls can be left installed and themselves secured to said sidewalls.

Abstract: A water-dispersible hybrid polymer comprises an ethylenically unsaturated polyurethane (core) onto which an addition polymer chain (shell) has been provided by polymerization, with the unsaturation of the polyurethane being achieved by the incorporation therein of dimethyl-m-isopropenyl benzyl isocyanate, and the acid number of the shell polymer being in the range of 30 to 120 (mg KOH/g). Aqueous dispersions of these hybrid polymers are pre-eminently suitable for use in aqueous coating compositions of the so-called clear coat type, particularly when stringent demands are imposed with regard to the acid resistance of the topcoats applied using these compositions.

Abstract: A process and apparatus for treating overspray from the spray application of waterborne coatings is provided, which includes at least an electrophoresis separation step (means) for recovering substantially all of solids and higher molecular weight water-soluble components and a second separation step (means) for recovering the remainder. The result of such treatment is a recyclable waterborne coating stream of substantially the same composition as the waterborne coating and a recyclable water stream containing substantially none of the resin or additive parts of the original waterborne coating. The process and apparatus are effective, efficient and relatively simple, and recycling is effected without the use of coagulants, detackifiers and other chemical additives which may complicate the recycling procedure and have a detrimental effect on the so recycled products.

Abstract: A heat exchanger having on a first and a second side inlets and outlets, respectively, for a preferably gaseous heat exchanging medium, and having a heat exchanging component made of a high thermal conductive material, such as metal, and comprised of a package of lamellae, in which the heat exchanging material has a structure permeable to the heat exchanging medium, and in which channels for the medium passing from the inlet side to the outlet side are formed, such that medium flowing in via the inlet channels can flow to the adjacent outlet channels at an angle to the direction of entry via the heat exchanging material.
