Abstract: A foaming system includes a foaming agent solution and a resin solution. In a preferred embodiment, the foaming agent solution includes from 1.6 to 4.8 mmols of dibutyl naphthalene sulfonic acid as surfactant, from 5 to 20 mmols of phosphoric acid as catalyst and foam intumescent agent, from 0 to 45.5 mmols of resorcinol as foam anti-collapsing agent, from 9.1 to 54.6 mmols of chloral hydrate as fire retardant agent and sufficient water to make a solution of about 5% solids concentration. The resin solution includes urea formaldehyde resin produced by reacting from 1.0 to 2.4 mols of formaldehyde per mol of urea, from 6.5 to 500 mmols polyethylene glycol as foam charring component, from 0.3 to 1.

Abstract: A contact adhesive that is a polymeric material with a major proportion of a tackifier is applied to sand in making a foundry mold. No curing step for the adhesive is required but instead pressure is applied to get the desired bonding together of the sand granules.

Abstract: A pressure-sensitive tape with a printable release coat on the side opposite to the adhesive face, the release coat including a vinyl film former, an acrylic resin and a polyamide plasticizing resin.

Abstract: A method of packaging bite-size pieces of a cheese product which includes heating the ingredients to a molten state with mixing, and then cooling and extruding the product under pressure in a continuous bar or rope at about 40.degree. to 60.degree.F. Thereafter subjecting it to shock cooling in a tunnel having a temperature in the range -100.degree. to 0.degree.F., by rapidly moving the bar through the tunnel so that it exits at a temperature in the range of 10.degree. to 30.degree.F. The bar is finally cut into bite-size pieces and individually packaged for the consumer at a rate of several hundred per minute.BACKGROUND AND DESCRIPTION OF THE INVENTIONThe subject invention is directed toward the art of food processing and, more particularly, to an improved method for preparing and wrapping a cheese product in bite-size pieces using a conventional high-speed cutting and wrapping machine of the type used to wrap candy kisses.

Abstract: The clams are first subjected to a shearing action in the first unit which is a rotating perforated drum having inwardly extending spokes with a rotating rotor disposed within the drum and off-set with respect to the drum axis. The rotor has outwardly extending spokes in intermeshing relationship with the drum spokes. In the first treating unit, the clams are partitioned into uneviscerated tongues, muscles, straps, siphons and occasional spines and then conveyed onto a classifier which separates the tongues from the remaining parts of the clams and discharges the spines to waste. The uneviscerated tongues are then fed into an eviscerator, which is identical in construction to the first unit but is operated at higher relative rotation between the drum and the rotor, where the tongues are flexed and subjected to shearing forces to expel the viscera.

Abstract: A solvent-free pressure-sensitive hot-melt adhesive contains:A. a block copolymer having the general configuration A--B--A wherein A is a polymer block of vinyl arene and B is a polymer block of conjugated diene,B. a tackifying resin system,C. a naphthenic process oil plasticizer having a naphthenic content between 52% and 75% and less than 5% aromatic by total carbon types of the process oil,D. a curing agent,E. a filler, andF. an antioxidant.The hot-melt adhesive described above can be applied to a number of backings without the use of solvents. The adhesive is rendered fluid by the use of heat and mechanical working. Adhesive tape made using the hot melt of the present formulation has all of the advantages inherent in the prior art tapes based upon solvent applied adhesives. The use of the hot-melt adhesive described above prevents air pollution which was inherent in the solvent removal step necessary in the prior art use of solvent based adhesive systems.

Abstract: This invention relates to polymerized polymeric vinyl films containing a minor portion of an anti-fogging and anti-tackifying agent, said agent comprising a partial ester of a water soluble C.sub.2-6 polyol with a C.sub.12-18 aliphatic monocarboxylic acid, a polyalkoxylated derivative of a partial ester of a water soluble C.sub.2-6 polyol with a C.sub.12-18 aliphatic monocarboxylic acid, the alkoxy groups therein having each 2-3 carbon atoms and the number of alkoxy groups being about 3-30 per molecule of said alkoxylated partial ester and in combination with both or each of the aforementioned partial esters, polyalkoxylated alkyl phenol, the alkoxy groups therein having each 2-4 carbon atoms and the number of alkoxy groups being about 3-50 per molecule.

Abstract: A machine for dispensing thick plastic film has two cradle rollers which carry a heavy roll of thick plastic film, two nipper rolls which draw film from the roll of plastic film, a timer regulated motor which drives the nipper rolls to dispense a pre-selected length of film and a knife to cut the film. The use of the knife reactivates the machanism to dispense a second given length of film and the process is infinitely repeated. The heavy plastic film dispensed is used to cover the sharp jagged edges of bones of primal or subprimal cuts of meat prior to the cuts being placed in plastic bags or wrapped in plastic film. The heavy plastic film protects the plastic bag or wrapping film from puncture by the jagged edges of the bones.

Abstract: A foamed plastic sheet is perforated medially before it is heated in an oven following which, it is conveyed between a pair of matching molds where a quad of egg cartons is formed in an upside down condition with locking lugs of a pair of cartons on one side of the perforated line facing the lugs of the other pair across the perforated line. Perforation of the sheet is made to relieve stress in the region where the lugs are formed.

Abstract: A water-based paint confers wet primed adhesion if its binder is a latex whose polymer is a vinyl chloride/acrylic or an all-acrylic containing polymerized therein (based on weight of main monomers) not only 0.3-5% of (meth) acrylic acid but also a fraction of hydroxymethyl diacetone acrylamide (HMDAA) which must be at least 1 % in case of vinyl chloride/acrylics and at least 2% in case of all-acrylics. But, surprisingly, when such a latex is diluted by blending with a vinyl acetate/acrylic latex which by itself does not confer wet primed adhesion, superior wet primed adhesion is obtainable even when the overall level of HMDAA is only 0.65% when the HMDAA latex is an all-acrylic and only 0.40% when the HMDAA latex is a vinyl chloride/acrylic.
