Abstract: The present version of the invention relates to the field of reading stands in general. This version of the invention discloses a portable stand that provides a magnifier for either writing or reading so that the user can engage in either activity and be afforded magnification of the written or printed page in a variety of locations and circumstances. The invention consists of a side support member, rear support member, and magnifying panel. The panel and support embers are manufactured of material that is clear, durable, scratch resistant, and rigid, such as acrylic or the like. The support members are rectangular in shape and are formed with a plurality of mounting grooves that run in parallel along the longitudinal axis of the support members. The side support member is formed with a retaining groove placed near the vertical or shorter edge of the member for receipt of the rear support member in tongue and groove fashion.

Abstract: Teeth within a patient's mouth are moved by an orthodontic method of treatment in which orthodontic appliances are installed at a desired time during the treatment on the teeth to be moved. Cortical bone adjacent the roots of the teeth to be moved is partially decorticated. Bone grafting material is installed between the partially decorticated cortical bone and the mucoperiosteum. The orthondontic appliances are adjusted thereafter as needed to move the teeth toward the positions desired. One orthodontic appliance which can be used for applying orthopedic force between a patient's anterior teeth on one side of an edentulous area and a patient's posterior teeth on the other side includes a front body, a back body and a screw member operatively connected between them. The screw member is adjustable to cause the front body and the back body to move away from one another and to move toward one another while transmitting an orthopedic force between them.

Abstract: A turbine meter used for measuring the volume of fluid flowing through a conduit includes an elongated housing having an upstream end and a downstream end and a rotor mounted within the housing. A plurality of turbine blades are mounted on the rotor at an angle with respect to the axis of rotation of the rotor which causes each of the rotor blades to have a high pressure surface which faces toward the upstream end of the housing. Each of the rotor blades also has a trailing edge closest to the downstream end of the housing. An extension is included at approximately the trailing edge on the high pressure surface of at least one and preferably a plurality of the rotor blades. The extension has a length and forms an angle with respect to the high pressure surface of the rotor blade on which it is mounted which causes the percentage of error of the accuracy of the meter across a chosen operating range of the meter to be within predetermined limits.

Abstract: An improved rotary fluid meter is provided having expansion chambers for conditioning pressure pulses that may occur in the flow of fluids. The pressure pulses, which inhibit the meter's ability to accurately measure, may originate from within a metering device or from without it. The pressure pulses may be generated upstream of the meter. Fluid flows into the meter through a fluid flow conduit. At least one flow conditioning chamber which is of such a volume and a shape as to enable it to substantially dampen pressure pulses so as to improve the accuracy of the rotary meter is provided along the fluid flow conduit.
