Abstract: A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system. A flow management screen station is provided which divides an incoming unacceptable flow into two fractional flows, neither of which is acceptable for feeding to the digester. One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow. The other output flow is concentrated in undersized chips and particles compared to the incoming flow. The output flows from the flow management screen are then fed to second and third screening stations which separate "overs" from the respective flows to provide acceptable flows to the digester.

Abstract: A flannelized film and a method of making a flannelized film are disclosed. Layers of plastic film are fed between two rollers meeting at a nip, the contiguous surfaces of the layers being coated with an adhesive or comprising a heat-softened coextruded layer. A layer of creped tissue comprising cellulosic fibers is laminated between the contiguous surfaces of the layers of plastic film to form an intermediate laminate structure. The cellulosic fibers of the intermediate laminate structure are split at the exit side of the nip such that a portion of the cellulosic fibers is adhered to each plastic layer and has components extending in a direction substantially perpendicular with respect to the plane of the plastic film. This gives the plastic film the look and feel of flannel for improving the aesthetics of disposable absorbent products such as diapers, feminine napkins and underpads.

To ease in handling prior to and during packaging, an adhesive restrains the bias flaps until the adhesive is at least partially melted during cooking. The insert may be arranged to prevent excessive bowing or curling of the central panel, and to improve venting or draining of fluids from the food product.

Abstract: An apparatus for folding and filling a plurality of cartons erected from a plurality of collapsed carton tubes includes an end flap alignment device attached to the conveying and folding mechanism of the apparatus. The end flap alignment device folds one of the bottom end flaps of the collapsed carton tube inwardly and in the same motion folds the top end flap which is also provided on the bottom of the carton tube outwardly so that the bottom end flap and the top end flap are aligned in the same plane. The end flap alignment device comprises a generally U-shaped fork comprising a base attached to a plate and two rods each connected at one end thereof to the base. The plate is attached to a reciprocable slide of the apparatus by a pivot rod. One end of the pivot rod is connected to a cam, which rides in a cam track. As the slide is reciprocated, the plate, including fork, is pivoted about the pivot rod.

Abstract: A disposable paperboard carton formed from an integral paperboard blank, has an improved opening feature, the improved opening feature comprised of a side wall of the carton having an outer layer of paperboard having a pull type closure tab which allows for the opening of the carton and dispensing of a contained product and which allows reclosure of the carton by inserting a portion of the tab in a cutout slot for storing the contents for further use, and an inner layer of paperboard having a T-shaped cutout for the pour spout. The pour spout size to be selected in accordance with the size of the product to be contained in the carton, with the closure tab being of a constant size and configuration. The closure tab being arranged on the outer layer so as to overlay the cutout formed in the inner layer.

Abstract: Apparatus for adjusting the amount of liquid dispensed through a liquid dispenser pump actuated by a bail. The pump includes a movable pump element and structure interconnecting the bail and the pump element including a rocker for imparting movement to the pump element and adjustment mechanism for selectively varying the pivotal movement imparted to the rocker by the bail.

Abstract: An apparatus is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, the embossed webs separated from one another and longitudinally displaced realtive to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. The resulting product exhibits enhanced softness and absorbence as compared with similar products comprising simultaneously embossed multi-ply webs.

Abstract: A substantially farinaceous, fiber-containing batter to produce a battered and fried food having reduced lipid retention and increased moisture content after frying. The preferred fibrous additive for this purpose is powdered cellulose; however, various dietary fibers such as oat fiber, soy fiber, pea fiber, or sugar beet fiber, to name only a few, may be used to achieve the same purpose. More specifically, the fibrous additive is preferably present in the batter in an amount of about 0.3-3.0% by weight of the batter having an average fiber length of from about 50-500 microns. The addition of fiber to a batter used for frying will allow food producers to provide a healthier fried food item which will be more appealing to a health conscious consumer. Moreover, the fiber additive can also enhance the appearance of the fried food by providing a golden yellow color after frying, rather than a non-uniform brown color containing brown and black batter particles.
