Abstract: Carbon dioxide may be used to adjust the electrical properties of papermaking compositions. Such papermaking compositions may contain a colloid phase, an aqueous phase, and optionally, pulp fibers. Examples of electrical properties whose values may be adjusted include zeta potential, electrical charge demand, conductivity, and streaming potential. The carbon dioxide may be introduced at many different points in a papermaking process, including calcium carbonate slurry feeds, pulp fiber slurries, diluted pulp fibers slurries, broke, and whitewater. When a value or range of values based upon an electrical property is predetermined, such as an optimal value or range, introduction of carbon dioxide may be used to adjust the value such that it is closer to the predetermined value.

Abstract: A manufactured dry ice product containing ozone entrapped or absorbed on said dry ice. The dry ice product can be used to chill and preserve food products and provides the added benefit of ozonation of the food product to kill bacteria. Novel processes for ozonating liquid and solid CO2 are provided.

Abstract: The wheelchair wheel cover includes a cover hub, radially extending disk and an integral radially outer wall that extends axially from the disk to a cover inboard edge. The cover hub includes a bore that receives a fixed bolt. The bolt passes through a wheel bearing with an inner race and an outer race. The bolt also passes through the frame of a wheelchair and screws into a nut. When the wheel cover is non-rotating, tightening the nut forces the cover hub against an inboard washer, forces the inboard washer against the inner race and forces the inner race against the frame. If the wheel cover is to rotate a thrust bearing is provided between the head of the axle bolt and the cover hub and the inboard washer is forced toward the outer race. The disk can be flat or sculptured and protects hands and fingers.

Abstract: Provided is a process for bleaching pulp with ozone. The process involves preparing a slurry of cellulosic pulp having a consistency in fibers of from 1-5 weight %. Such a low consistency slurry is then mixed with ozone under high shear conditions. The ozone is then maintained in contact with the cellulosic fibers to effect bleaching of the fibers. The present process offers the advantages of bleaching using a low consistency slurry, with the added advantages of employing ozone.

Abstract: Cellulosic products comprising cellulosic fibers and precipitated calcium carbonate prepared in-situ during papermaking are described. The precipitated calcium carbonate is deposited on the cellulosic fibers and is present in a variety of sizes, shapes and morphologies, and is present in the cellulosic products on all physical features of the cellulosic fibers. At least a portion of the precipitated calcium carbonate is present with the fiber based on interaction with one or more chemicals used in papermaking.

Abstract: Methods of cleaning metal containers, and containers having internal metal linings are described. The methods comprise the steps of exposing the internal metallic surface to a composition comprising ozone, the internal metallic surface having thereon a residue, contacting the composition comprising ozone with the internal metallic surface for a time sufficient to either remove the residue, chemically modify the residue to form a modified residue that may be removed by other means, or deactivate the residue.

Abstract: Provided is a process for bleaching pulp with ozone. The process involves preparing a slurry of cellulosic pulp having a consistency in fibers of from 1 up to 5 weight %. Such a low consistency slurry is then mixed with high partial pressure ozone under high shear conditions. The ozone is then maintained in contact with the cellulosic fibers to effect bleaching of the fibers. The present process offers the advantages of bleaching using a low consistency slurry, with the added advantages of employing ozone.

Abstract: This invention is directed to a method of using a two spindle Hurth-Module multi-spindle (or similar) cutting machine to accomplish face hobbing of hypoid and spiral bevel gear sets. A first cutter mounted on a first spindle would rough cut the gears and a second cutter mounted on a second spindle would finish the gears with both cutters using a face hobbing process. According to this process, multiple cutters are used for a single gear, but on a single machine, thereby reducing cutter wear, increasing cutter life, and raising production output of the multi-spindle machine by utilizing both spindles. In one embodiment, a fine pitch cutter is used to create the initial rough-cut of the gear, and a second coarse pitch cutter is used to create the finish cut of the gear.

Abstract: Methods of bleaching cellulose pulp using chlorine dioxide and ozone in one and the same single stage of a bleaching sequence having a plurality of stages are presented. In its broadest embodiment the method comprises controlling a ratio of chlorine dioxide to ozone within a single stage of a first bleaching sequence in a range effective to achieve strength characteristics of a final paper elaborated from the first bleaching sequence at least as great as strength characteristics when compared to a control bleaching sequence, the control bleaching sequence being the same in all respects as the first bleaching sequence except not employing ozone in a stage, and for essentially the same final brightness of pulp elaborated from the first and the control bleaching sequence. Cellulose pulps made using the methods of the invention are also described.

Abstract: Induction hardening of heat treated gear teeth which includes the steps of rough and finish cutting the gear teeth, or alternatively cutting the gear teeth to their final configuration utilizing a one cut method, carburizing the gear and in particular, the gear teeth, slow cooling, or alternatively drawing back the gear so the gear teeth are not hard, and induction hardening the gear teeth heating only the surface of the gear teeth. This results in improved strength for the gear teeth as a result of increased residual compressive stresses therein. Induction heating of only the surface of the gear teeth results in an relatively low case depth in the root of the gear teeth.

Abstract: A golf club ball-striking face (6) utilizing a metal with ten times or higher damping capacity compare to the steels presently in use for club faces. The metal has the strength near that of the steels. The preferred metal is of the class of shape memory metals of alloys including: copper, nickel, aluminum, and manganese. The face is an insert plate whose front ball striking surface is narrower than its rear surface and is secured into a cavity formed in the club head, where the plate may be as thin as 0.010 inches or the plate may extend to nearly the entire thickness of the club head.
