Abstract: This invention relates to gap/edge bead detection systems. Such structures of this type, generally, employ the use of fiber optic sensor assemblies positioned at the edges of the web and/or between gaps in the sheets in order to detect the absence of material.

Abstract: This invention relates to carrier straps for carrying prepared foods, such as rotisserie chickens, roasted turkey, roasted ham, side dishes or deserts. Such structures of this type, generally, employ a one-handed, paperboard strap which is wrapped around the plastic tray and plastic domed lid package in which the prepared food is located. The carrier strap secures the prepared food package and transports it so that the purchaser's hands do not get greasy or hot. Also, the carrier strap functions to provide a printable surface to identify flavor and brand.

Abstract: This invention relates to a loose draw detector for a paper machine wet press. Such structure of this type, generally, use laser triangulation displacement sensors mounted and positioned to measure the point of web release from the center roll and measure paper web wrinkles in the form of rapid fluctuations/decreases in the standoff distance between sensors and the web passing over the leadout roll to determine loose draw.

Abstract: This invention relates to a laminate substrate. An exemplary embodiment comprises a paperboard layer with a heat sealable layer secured substantially adjacent to one side of the paperboard layer. A co-extruded layer is secured substantially adjacent to the other side of the paperboard layer. The co-extruded layer has five layers: a heat sealable layer secured to the paperboard layer, a first tie layer secured adjacent to the heat sealable layer, a semi-crystalline nylon layer secured adjacent to the first tie layer, a second tie layer secured adjacent to the semi-crystalline nylon layer, and a heat sealable layer secured adjacent to the second tie layer. A fourth heat sealable layer is secured adjacent to the co-extruded layer.

Abstract: This invention relates to a modification for a round-corner flip top cigarette pack and the like. Such structures of this type, generally, relocate the inner frame in order to improve reclosability of the pack.

Abstract: A two piece paperboard package that houses a unit dose product on an internal slide card within an outer paperboard shell. This package may have one or more internal or external lock(s) that prevent the slide card from being pulled out without triggering some type of lock release mechanism. This package is focused around providing a child resistant, senior-friendly unit dose package that can be opened and closed numerous times and then finally disposed of.

Abstract: The envelope of the present invention is prepared from a single blank of material to include easy opening means and security features for tamper evident delivery of credit cards, debit cards and other sensitive material. The envelope structure includes a bangtail flap foldably attached to the rear panel of the envelope and folded inside the envelope, a pair of perforated lines located on each side of the rear panel for providing access to the inside bangtail flap, and a separate opening means for the closure flap.

Abstract: This invention relates to a height measurement apparatus for determining volume/density of wood chips on a conveyor. Such structures of this type, generally, employ the use of contacts that ride on top of the pile of wood chips in order to more accurately measure the volume and density of the wood chips.

Abstract: This invention relates to an apparatus and method for determining paperboard thermal conductivity. Such structures of this type, generally, determine the thermal conductivity of a planar material, such as paperboard or insulating foams. The apparatus is designed to characterize the heat flow from a heated brass cylinder, through a flat paperboard sample, and into another brass cylinder. The brass cylinders are fully insulated, except at the sample interface. During the test, which is in a transient state, the hot mass loses energy, raising the temperature of the cooler mass as the two masses approach an intermediate equilibrium temperature. Knowing that the brass masses are fully insulated, except for the heat transfer interface, and knowing the physical properties of the masses, the only unknown in the mathematical model describing the experiment is the thermal conductivity, k, of the paperboard sample, which enables its determination.

Abstract: This invention relates to calendering systems. Such structures of this type, generally, employ the use of hard and soft nips to provide excellent smoothness without gloss mottle.

Abstract: This invention relates to the construction of sleeves for use with paperboard cups. Such structures of this type, generally, employ a paperboard sleeve backed with hot-melt glue dots which are used to improve the insulating characteristics of a paperboard cup to the same level of common polystyrene cups.

Abstract: This invention relates to automotive evaporative emissions canisters. Such structures of this type employ a carbon-filled foam which adds adsorptive performance to the canister without having to enlarge the canister or having to change the carbon in the canister to a higher performance carbon.

Abstract: Paper web formation analyzers can be employed both on operating paper machines at high speed and on cut samples as a desk top unit, so as to unify formation evaluation for both situations.

Abstract: This invention relates to electro-magnetic rappers which are used on precipitators. Such structures of this type, generally, employ the use of a wear guide which reduces rapper liner wear.

Abstract: This invention relates to chemical additive management systems. Such structures of this type, generally, allow a manufacturer to determine if a chemical additive to be used will contain a chemical component or reaction product that is of toxicological concern to the end-user.

Abstract: This invention relates to paperboard lids having a radiation cured overprint varnish. Such structures of this type, generally, protect the graphics which are printed upon the paperboard lid such that the graphics are not distorted and/or marred during the platen sealing process.
