摘要： A temperature compensating circuit for taking into account operating temperature changes of a Hall effect transducer to compensate for Hall output DC offset changes using a resistance circuit including a thermistor for offset feedback control of an operational amplifier in accordance with varying temperature. The circuit also includes a load response input portion to power the Hall effect transducer to compensate for Hall gain change versus temperature.

摘要： The present invention relates to non-pigmented jet ink compositions and to a method of producing opaque coded messages therewith. The compositions comprise, on a weight basis, between 2 and 15% of a gellable cellulose ester having a hydroxyl content of from 2 to 8%, from 1.5 to 15% of a binding agent selected from the group consisting of alkali soluble rosin type and maleic type resins, polyvinyl acetate resins, and acrylic resins, and a solvent blend, the blend consisting essentially of an organic solvent system and a non-solvent, said non-solvent comprising from 2 to 10% by weight of the ink composition. Preferred solvents are methanol, acetone, methyl ethyl ketone and ethyl acetate, while the preferred non-solvent is water. Upon evaporation of the solvent blend, the resultant dry films scatter light incident thereto whereby the opaque images are produced. In a particularly preferred embodiment, a hygroscopic salt is included in the composition as an opacity enhancement agent.

摘要： A method and system for applying a foamed binding agent to a fibrous web is disclosed. The invention is characterized by the use of an extruder having an upper lip extending 1/16 to 1/4 inch beyond the lower lip, and by the drawing of a vacuum beneath the applied foam, said characteristics being critical to the formation of a uniform foam layer atop the web. A second, more substantial vacuum is then applied beneath the web to essentially completely draw the binding agent into the web thereby providing substantial inter-fiber bonding.

摘要： Apparatus for winding webs from a large-diameter roll onto cores to form smaller diameter rolls wherein the cores are supported on mandrels mounted at one end on a turret that is indexed between a core loading station, operational stations including at least a web winding station, and a wound-web unloading station. A pair of axially spaced star wheels keyed to a freely rotatable shaft having its axis parallel to the axes of the mandrels sequentially are engaged by, are rotated by, and are disengaged from a mandrel as it is moved between the core loading and winding stations to ensure alignment of the free end of the mandrel for supporting engagement with a provided latching cup operative to engage and steady the mandrel in the operational stations.

摘要： A method is provided for polymerizing lignosulfonate materials without undesirable viscosity build-up or gelling. The method comprises the steps of premethylolating the lignosulfonate under alkaline conditions followed by condensation of the premethylolated lignosulfonate at elevated temperatures and under neutral and acidic conditions.The resultant products are useful in any of a variety of applications wherein the surface active properties of lignosulfonates may be desirable. The products are useful as dispersants and especially as dye dispersants.

摘要： Methods by which a dry-formed loose fibrous web is bonded by applying to one of its surfaces a low add-on level of a relatively high binder solids concentration bonding material to form a once-bonded web, and to the other side of the web, a greater add-on level of a relatively lower solids concentration bonding material, the first-applied emulsion preferably adding from about 20% to about 40% binder solids by weight, and the second-applied adding the rest of the total binder solids to be included in the fibrous web product. The bonding material can be a solution or emulsion. Preferably, the first and second-applied bonding materials are water-based latex emulsions, the solids concentration of the first-applied emulsion is from about 15% to about 25% by weight, that of the second-applied emulsion is from about 10% to about 20% by weight based on the total binder solids to be included in the fibrous web product, and a vacuum draws the second-applied bonding material into the web.
