  • Patent number: 4823783
    Abstract: Method and apparatus for ultrasonically bonding continuously moving webs to one another using a stationary vibrating horn and a relatively slick, non-thermally softenable moving slip layer interposed between the webs to be bonded and the horn to prevent web damage. Interposing the slip layer between the webs to be bonded and the ultrasonic horn improves both the quality and efficiency of web bonding. It reduces friction between the travelling webs and the substantially stationary ultrasonic horn not only due to its relatively slick surface, but also due to the compressive force which the slip layer exerts upon the webs to be bonded. This in turn minimizes jamming and hangups in the very limited clearance existing between the rotating anvil roll and the substantially stationary vibrating ultrasonic horn. In addition, the slip layer maximizes retention of heat either generated in the laminate web by the ultrasonic horn or transferred to the laminate web structure by preheating one or more of the webs.

  • Patent number: 4820447
    Abstract: Disclosed is a mild skin cleansing soap bar composition comprising: (1) 50-90% soap, and (2) a hydrated cationic polymeric skin conditioner. The physical composition of the bar is such that the hydrated polymer is substantially uniformly distributed and well incorporated in the soap. The hydrated cationic polymer improves the mildness of the soap bar to a level approaching that of bars made with very mild synthetic surfactants, while maintaining the desirable physical characteristics of a pure soap bar without the polymer.

  • Patent number: 4818555
    Abstract: Low viscosity evaporative orange juice concentrates having less cooked off-flavor, as measured by the % retained valencene, are disclosed. These concentrates are preferably obtained by an evaporative concentration process which starts with a feed juice having a relatively low viscosity and sinking pulp level and which heats this feed juice to temperature no higher than about 180.degree. F. to avoid the generation of cooked off-flavor. In addition, the juice, at a critical solids content, is headed under vacuum to temperatures in the range of from about 160.degree. to about 180.degree. F. under conditions of high shear across the heated surface of the evaporator to insure effective deactivation of pectinesterase enzymes initially present in the feed juice.

  • Patent number: 4813539
    Abstract: A carton for a roll-type product which is dispensed by unrolling, withdrawing and separating a piece of the product from that remaining on the roll.

The end walls have an inner end flap with an orifice and an overlapping end flap with the projection hingedly attached to it and extending through the orifice. The projection has a central section which is generally triangular with the apex located distally of the hinge. Wing sections flank the central section and these are adapted to be folded back from the central section as the projection is inserted through the orifice, to form the projection into an open-sided generally pyramidal shape which is deflectable towards the product core following insertion.

  • Patent number: 4806632
    Abstract: The invention is a process for post-hydrogenating sucrose polyesters with hydrogen gas in the presence of a catalytically effective amount of hydrogenation catalyst, at a temperature of from about 250.degree. F. (121.degree. C.) to about 450.degree. F. (232.degree. C.). Post-hydrogenation can be used to make sucrose polyesters that are different from those made by esterification. Preferably, the hydrogen pressure is at least about 20 psig. Increased hydrogen pressure overcomes steric hindrance of certain kinds of sucrose polyester molecules, allowing more complete hydrogenation of the fatty acids.
