Abstract: Oil-in-alcohol microemulsion-containing composition concentrate stabilized by at least one emulsifier and containing at least one organic hydrophobizing agent having a metal adsorbing moiety therein. The composition concentrate, when diluted with water, is useful in automotive coolant systems as an antifreeze.

Abstract: A silicone/silicate-containing antifreeze characterized by dilute aqueous stability includes substituted organosilicon carboxylates characterized by the following formula: ##STR1## wherein M is a monovalent cation such as, for example, sodium; Z represents a moiety hydrolyzable to silanol; R.sup.1 represents hydrogen, a monovalent hydrocarbon radical such as methyl, ethyl, phenyl, and the like or a substituted monovalent hydrocarbon radical; a has a value from 0 to 20, b has a value of 1 or 2, c has a value of 0 or 1, n has a value of 2, 3, or 4, and m has a value of from 3 to 15 when a is other than 0 and from about 7 to about 15 when a is 0.

Abstract: Oil-in-alcohol microemulsion-containing composition concentrate containing oil-soluble corrosion inhibitor. The composition concentrate, when diluted with water, is useful in automotive coolant systems as an antifreeze.

Abstract: An automobile coolant concentrate comprising (a) a liquid polyhydric alcohol, and (b) a corrosion inhibitor comprising an alkali metal antimony tartrate, preferably with an azole compound, in a corrosion inhibitory amount with respect to corrosion of lead-containing solders.

Abstract: Antifreeze composition containing at least one organophosphate in buffer/alcohol, together with method of using and composition.

Abstract: Antifreeze composition and composition concentrate containing at least one organophosphate and at least one silicate in buffer/alcohol, together with method of making and using the composition and composition concentrate.

Abstract: A buffer and silicone/silicate-containing antifreeze concentrate characterized by storage stability and minimized corrosiveness toward metals when diluted to make an antifreeze.

Abstract: A process and apparatus for producing integral interlocking closure film stock useful in making reclosable containers by extruding a film of molten thermoplastic material onto a casting roll, extruding closure elements to contact and join said film at a point between about one inch and about five inches prior to the tangency line of the film on the periphery of the casting roll, partially cooling the closure elements with liquid coolant starting anywhere within the region between the closure element extrusion exits, and the tangency line of a film of molten thermoplastic material and the periphery of the casting roll, and further cooling the closure elements by directing them past additional cooling assemblies. Stripping means are employed to remove liquid coolant from the cooled integral interlocking closure film stock material produced.

Abstract: An interlocking closure fastening device comprising a first closure element having an omega-shaped profile portion, and a second complementary closure element having a plurality of omega-shaped profile portions spaced to interdigitate with the first closure element and occlude with the first closure element. The profile portion of the first closure element is made from a stiff resin material, and is attached to a base portion made from a flexible resin material. The second closure element is made from a stiff resin material. The base portions of the second closure element are spaced from each other and interconnected by a flexible connecting portion. The closure device is adapted for use with reclosable plastic freezer storage and cooking bags.

Abstract: A side-sealed bag with a closure device. The bag has a peripheral bead seal and an upper flat seal extending inwardly from the bead seal between the top and the closure elements and a lower flat seal extending inwardly from the bead seal between the bottom and the closure elements.
