    Abstract: Orthodontic brackets made of a light-transmissive material such as plastic or ceramic have a removable, water-based colorant to facilitate identification of the bracket and alignment of the bracket on the patient's tooth. The colorant is received in a ligature channel of the bracket and is visible through adjacent tiewings of the bracket. The colorant is protected by the overlying tiewings from inadvertent damage or removal as might otherwise occur during initial handling and placement of the bracket.

    Abstract: A fiber optic ribbon cable has release elements manufactured in line with the ribbon cable so as to provide access points to the optical fibers contained therein to allow for easy application of a connector in the field. A pair of adhesive tape layers is provided about the optical fibers to create a fiber optic ribbon cable. At least one release element is provided between the adhesive tape layers and the optical fibers at one or more access points along the ribbon cable to allow for subsequent connectorization of the fibers therein. When the ribbon cable needs to be equipped with a connector, the cable is cut near the midpoint of one of the access point. After the cable is cut the adhesive tape layers and the at least one release element may be easily peeled back exposing the optical fibers. A connector is then installed onto the exposed fibers. The at least one release element is removed from the tape layers and the tape is then secured to the connector with any excess tape being trimmed off.

    Abstract: A clamping and tensioning system for securing a sheet of photoconductor film to an outer circumferential surface of a carrier drum includes a clamp rod mounted to the carrier drum by first and second mounting blocks. The first and second mounting blocks include elongated slots that allow the clamp rod to rotate about its longitudinal axis and further permit linear radial movement of the clamp rod with respect to the carrier drum. The clamp rod includes mounting pins and spring tabs that engage leading and trailing edges of the photoconductor film. The leading and trailing edges of the photoconductor film are releasibly clamped to the clamp rod by a clamp bar. Leaf spring elements associated with the first and second mounting blocks bias the clamp rod radially inward to a first position wherein the photoconductor film extends loosely about the outer surface of the carrier drum. The photoconductor film is tensioned by rotating the clamp rod about its longitudinal axis which in turn winds the leading and trailing edges of the photoconductor film about the clamp rod. As the clamp rod is rotated, it moves radially outward with respect to the carrier drum along the elongated slots against the bias of the leaf spring elements. The clamp rod is held in a second position wherein the sheet of photoconductor film is securely tensioned about the outer surface of the carrier drum by a releasible split clamp collar.

    Abstract translation: 用于将感光体膜片固定到载体鼓的外周表面的夹持和张紧系统包括通过第一和第二安装块安装到载体鼓的夹紧杆。 第一和第二安装块包括细长的槽，其允许夹紧杆围绕其纵向轴线旋转，并进一步允许夹紧杆相对于承载滚筒的线性径向移动。 夹紧杆包括安装销和弹簧片，其接合感光膜的前缘和后缘。 光电导体膜的前缘和后缘通过夹杆可释放地夹紧到夹紧杆上。 与第一和第二安装块相关联的板簧元件将夹紧杆径向向内偏压到第一位置，其中光电导体膜松散地延伸在载体鼓的外表面上。 通过围绕其纵向轴线旋转夹持杆来张紧感光膜，该纵向轴又使感光膜的前缘和后缘围绕夹紧杆卷绕。 当夹紧杆旋转时，其相对于载体滚筒沿着细长狭槽径向向外移动，抵抗板簧元件的偏压。 夹持杆保持在第二位置，其中感光体膜片通过可释放的分开的夹紧套环被牢固地张紧在承载鼓的外表面上。

    Abstract: A combined skirted oil-sorbing boom and oil-sorbing sweep has a buoyant inner core and an oil-sorbent outer core of a spirally wound sheet of polymeric, oleophilic, hydrophobic microfibers. Adhesively bonded to a sheet of the microfibers at the outer face of the outer core is an open-mesh netting of polymeric monofilaments that are fused at their crossings. The netting and the sheet to which it is adhered extend from the outer core to form a depending skirt which acts as a barrier to oil that is being sorbed by the microfibers. The buoyant inner core can be an open-cell foam that sorbs oil slowly, thus supplementing the oil-sorbing capability without significant loss of freeboard.

    Abstract: Light emitting apparatus for curing photocurable dental material includes a handpiece having a housing, a depending handle and a detachable light guide. The light guide is received in a head connected to the housing. Rotational movement of the head relative to the housing also rotatably moves the light guide so that the guide may be turned by the same hand of the user that is grasping the handle. Additionally, a pivotal connection between the housing and the handle permits limited pivotal adjustment of the angle of the housing relative to the handle for improved manipulation and user comfort. A base of the apparatus includes an upright pedestal that houses a device for determining the intensity of light provided by the light guide.
