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.

After preparation of the ammonium form, the zeolite is contacted with a solution containing the desired metal cation while simultaneously maintaining the pH at between about 9.0 and 12.0 to provide a final product zeolite wherein the desired metal cation will correspond to at least about 0.5 of the total zeolitic cations.

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 corrosion-inhibited heat transfer composition concentrate comprising an alcohol, an organosiloxane/silicate copolymer, and a corrosion inhibiting amount of a nitrate salt. Such coolant concentrate may suitably be diluted with from about 25% to about 90% by weight of water based upon the weight of the concentrate, to form an aqueous composition which has particular utility as a corrosion-inhibited heat transfer composition for heat exchange systems, for example, those employed with internal combustion engines. Such compositions are highly effective in reducing corrosion in heat exchange systems containing components of aluminum construction.

Abstract: Synthesis gas comprising carbon monoxide and hydrogen is converted to C.sub.5.sup.+ hydrocarbons suitable for use as liquid motor fuels by contact with a dual catalyst composition capable of ensuring the production of only relatively minor amounts of heavy products boiling beyond the diesel oil range. The catalyst composition, having desirable stability during continuous production operation, employs a Fischer-Tropsch catalyst, together with a co-catalyst/support component. The latter component is a steam-stabilized zeolite Y catalyst of hydrophobic character, desirably in acid-extracted form.

Abstract: The conversion of synthesis gas to liquid molar fuels by means of a cobalt Fischer-Tropsch catalyst composition is enhanced by the addition of molybdenum, tungsten or a combination thereof as an additional component of said composition. The presence of the additive component increases the olefinic content of the hydrocarbon products produced. The catalyst composition can advantageously include a support component, such as a molecular sieve, co-catalyst/support component or a combination of such support components.

Abstract: Dentifrice compositions are provided having an effervescent and cleansing action. The dentifrice compositions are formed from an essentially anhydrous dentifrice base medium and an inorganic oxide material containing an adsorbed gas. Upon contact of the dentifrice composition with water, an effervescent action occurs as the gas is desorbed from the inorganic oxide material.

C. with advantageously reduced selectivity of said cobalt for methane in said conversion. The catalyst composition can advantageously include a support component, such as a molecular sieve, co-catalyst/support component or a combination of such support components.

Abstract: Disclosed is a hydrocarbon conversion process in which solid particles capable of promoting the conversion of a sulfur-containing hydrocarbon feedstock in intimate admixture with a minor amount of discrete entities effective to reduce atmospheric emissions of sulfur oxides from the process are circulated between at least one reaction zone wherein sulfur-containing deposits are formed on the solid particles, and at least one regeneration zone wherein at least a portion of the deposits is removed from the solid particles to produce regenerated solid particles which are circulated to the reaction zone and sulfur oxides; and the discrete entities are capable of associating with sulfur trioxide in the regeneration zone and of disassociating with sulfur trioxide in the reaction zone. The improvement comprises contacting the regenerated solid particles and discrete entities with at least one gaseous reducing medium prior to the solid particles and discrete entities entering the reaction zone.
