Abstract: Keyed fluid-handling devices comprise a fluid-handling device such as a filter, a bypass, or an adapter and an optical key. The optical keys are amenable to all types of filter component and can be readily retrofitted to existing designs. The optical keys may be formed from a variety of materials and combination of phases. That is, optical keys may comprise one or more solid materials, or perhaps may result from a combination of: solid materials, such as in transparent or semi-transparent polymers or glass; liquid fluids, such as water; and gaseous gaps such as an air gap. Optical keys may be light conduits or light guides. Filter manifolds comprise optical locks to ensure compatibility of the filter components.

Abstract: Provided are flexible panel devices that use desiccants for heat and mass transfer processes, including but not limited to air conditioning systems, for example, liquid desiccant air conditioning (LDAC) applications wherein the liquid desiccant is contained in a panel that comprises at least one hydrophobic separation layer, which allows water vapor transfer between the air and liquid desiccant and enable dehumidification and humidification of the air. The flexible panel devices can be installed on an absorber (conditioner) side or a desorber (regenerator) side or both of a LDAC system. The devices have two flexible layers, at least one of which comprises a flexible and water vapor permeable hydrophobic separation layer, that form a desiccant flow channel and a desiccant flow distributor located therein. The two flexible layers may both be permeable hydrophobic separation layers, or they may comprise one permeable hydrophobic separation layer along with a non-porous layer.

Abstract: A package for consumable products is disclosed. In one embodiment, the package includes a connecting member that connects a group of products together. The connecting member may comprise one or more bands that partially encircle the products or connect the products along a top surface. In addition, the package configuration may include a locking element that is configured to attach adjacent packages together or to attach the package to an adjacent structure, such as the railing of a shopping cart.

Abstract: In manufacturing a moving web, such as a tissue sheet, the web is transported at very high speeds, often in an unsupported manner, which can result in unstable operations regarding handling and winding of the web. This is particularly true in the region between the creping blade and the reel for a lightweight, low modulus tissue sheet that is characteristic of a high-quality, soft tissue basesheet. To provide an improved means of controlling the tissue web during manufacture and to improve the manufacturing rate, an apparatus and method of stabilizing the moving web that incorporates a creping blade foil, one or more aerodynamic sheet stabilizing foils, and a roll foil in a specific relationship to each other is disclosed. This method has been shown to improve the stability of a moving tissue web, allow for a higher rate of operation, and enable the production of softer tissue basesheets.

Abstract: A method of cleaning tissue webs in a rewinder utilize the Coanda effect to produce an improved tissue product. The Coanda effect web cleaner utilizes the smooth flow of a thin layer of air to scrub off dust and lint embedded and entangled in the web surface while stabilizing the web in its travel. Two of these Coanda effect web cleaners arranged on opposite sides of a multiple-ply web in a rewinder are effective when operated according to the method of the invention to produce a rewound tissue with an unexpectedly low loose dust and lint count on its surfaces.

Abstract: A tissue product and method are disclosed in which individual discrete tissue sheets which overlap each other are wound into a roll. The overlapping provides a means for pop-up, one-at-a-time tissue dispensing. Preferably, the sheets are dispensed axially from a coreless roll. The overlapping sheets within the roll can be interleaved as well as overlapped to increase the frictional engagement between successive sheets. This product form is useful for a variety of tissue products, such as facial tissue, bath tissue, kitchen towels and napkins.

Abstract: A method and apparatus for testing the hardness of wound rolls, such as paper rolls, which yields quantitative information which is reproducible from roll to roll and under various conditions of testing. The apparatus can be operated much like a backtender's stick, to simply strike the roll at a point where hardness is to be determined with a force variable between certain limits as determined by the operator using the stick. The apparatus includes an accelerometer mounted in a striker associated with circuitry for producing signals relating to (a) the energy of the impact between the striker and roll and (b) the peak deceleration of the striker. Those signals are processed to produce a roll hardness measure, which can be correlated to a commonly used Rho scale if desired, and which is repeatable irrespective of the force used by the operator to cause the impact.

Abstract: Separate density profiles are obtained for each station of a multi-station winder. The technique requires a single processor for simultaneously monitoring the density of any number of rolls being wound. The density may also be monitored for the unwind roll for determination of roll structuring changes by a winder. A simple system is provided in which each of the rolls is provided with an encoder. The encoder of a center roll of fixed diameter produces a fixed number of pulses per revolution representing paper length and the pulses produced by the encoders of each of the winding stations are counted along with the pulses produced by the winder of the center fixed diameter roll for computing density from roll and angular parameters and basis weight.
