Abstract: A method for manufacturing a bevel gear member, comprises the steps of providing a bevel gear blank having a gearhead, forming gear teeth on the gearhead of the bevel gear blank by simultaneously cutting gear tooth top land, gear tooth side profile and a bottom land to form an unfinished bevel gear member using a face hobbing process, and machining at least one selected surface of the unfinished bevel gear member using the top lands of said gear teeth as a datum for centering the unfinished bevel gear member, thus forming a finished product. The method is applicable for manufacturing the bevel gear member both with shaft axially extending from the gearhead and without the shaft. The bevel gear members manufactured with this method exhibit reduced runout and require simpler, less expensive tooling.

Novel processes for ozonating liquid and solid CO2 are provided.

Abstract: A scroll wheel assembly includes a rotatable member. Encoded rotation of the rotating member causes scrolling of an image on a display screen along an axis. An actuator is located within the rotational member. Pressure on different parts of the actuator causes scrolling of the image in opposing directions along a second axis. Pressure upon additional parts of the actuator can provide additional screen functions. Functions and commands caused by manipulation of the rotatable member or actuator may also be programmable.

Abstract: Methods of treating and sanitizing foods and other targeted objects, including the use of ozone and a method for providing a liquid dosed with pressurized ozone. The ozonated liquid of the invention is particularly useful for treating food products, food storage, and food transportation devices as well as treating water, or other target objects. Included is a method or pressurizing an ozone-containing stream without destroying the ozone or contaminating the stream with oil or water. The pressurized ozone-containing stream is then used to dose a liquid, which in turn is used to sanitize or treat a target object.

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: Methods of cooling and sanitation of target items, particularly food products, food storage, and food transportation devices. A treating agent containing a sanitizing agent entrapped by or absorbed in or on a cooling agent is used when processing, transporting, displaying, or storing of target items. The treating agent can be used to chill and preserve target items, and while providing the added benefit of sanitizing the target item. This disclosure also discusses novel processes for using a treating agent to process, store, or package target items using a treating agent containing a cooling agent, such as solid carbon dioxide (“dry ice”), and a sanitizing agent, such as ozone.

Abstract: The use of ozone in liquid carbon dioxide as a sterilant for use in aseptic packaging. The low temperature provided by liquid CO2 further eliminates microbiological hazards. The combination of these two chemicals will enable the aseptic industry achieve higher process efficiencies and improved sterilization without the drawbacks currently seen with the use of hydrogen peroxide.

Abstract: Methods for treating, and/or cooling of a target item to reduce or eliminate biological microorganisms in or on a target item. The treating agent of the invention is particularly useful for treating food products, food storage, and food transportation devices as well as treating water, or other target objects. A treating agent containing a sanitizing agent entrapped by or absorbed in or on a cooling agent is used when processing, transporting, displaying, or storing of target items. The treating agent can be used to chill and preserve target items while providing the added benefit of sanitizing the target item. The novel processes of the current invention provide for using a treating agent to process, store, or package target items using a treating agent containing a cooling agent, such as solid carbon dioxide (“dry ice”), and a sanitizing agent, such as ozone.

Abstract: Keyboard input functionality is provided when a removable portion of the keyboard is docked into the base unit. The removable portion may be the undocked from the base unit. A keyboard removable portion may include alphanumeric functionality and may be of a reduced size for off-desk implementation. Since the base of the keyboard may be wired, it may also charge the removable portion of the keyboard. The base may also include the wireless receiver for cooperating with a wireless keyboard or wireless mouse.

Abstract: A gaseous oxygen resonance igniter includes a body with a first inlet for gaseous oxygen incorporating a supersonic nozzle. An outlet from the body incorporates an orifice of predetermined size to maintain a desired pressure in the body. An aperture in the body opposite the first inlet provides a port to a ceramic resonance cavity. A ceramic bleed disc is engaged at a second end of the resonance cavity. An end cap incorporates a plenum adapted to receive high temperature oxygen flow from the resonance cavity through the bleed disc. An exhaust port is connected to the plenum for the high temperature oxygen which flows to a mixing chamber which introduces pilot fuel for ignition as a combustion initiation torch.

Abstract: A mouse has sufficient width to support the distal phalanges of a user's ring finger and little finger while the user's middle finger is positioned over a secondary button of the mouse. The mouse also provides at least one side button positioned so that it is not contacted by the user's thumb during “pinching” of the mouse but is easily accessible by the user's thumb. In addition, the mouse provides a wheel with a large number of ribs that increase friction between the user's finger and the wheel.

Abstract: A method and device for providing access, via a single point, to information stored on multiple data sources. One embodiment comprises a method in which first an interface (port) receives a call specifying a user identifier and a set of information from an application program. The set of information comprises a number of fields, where the fields correspond to information which is physically stored over a number of databases. Next, the method determines the location of the fields of information corresponding to the user identifier. Next, using the identifier which the application program passed in, the method retrieves the information. For example, the method may first retrieve information corresponding to a first field from a first database. Then, the method may retrieve information corresponding to a second field from a second database. Then, the method provides the information to the application program.

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.
