    • A blockage clearing apparatus to clear blockages in both drain valves and in pipes. A cylindrical housing holds a piston connected to a cylindrical rod. The piston moves within the cylindrical housing in response to pressure placed on the piston either manually by an operator or by hydraulic or pneumatic power. As the piston moves in the cylindrical housing, the rod connected to the piston moves back and forth in response to the motion of the piston. The blockage clearing apparatus is mounted to a drain valve or to an opening in a pipe. When operated by pneumatic power, valves, manual or solenoid controlled, will control the flow of air in and out of ports in the cylindrical housing, creating a pressure differential within the housing to actuate the motion of the piston, hence, of the rod. The rod will extend from the housing through an open drain valve and into the pipe that is in fluid communication with the drain valve. The rod will break open any blockages in either the drain valve or in the pipe, which inhibits fluid communication between the interior of the pipe and the drain valve. The blockage clearing apparatus can be placed into a specially created opening in a pipe where it is predictable blockages may occur. The blockage clearing apparatus can be actuated to extend and to retract the cylindrical rod to break loose any blockages occurring at the point the blocking clearing apparatus is mounted in the pipe.
    • 堵塞清除装置清除排水阀和管道中的堵塞。 圆柱形壳体保持连接到圆柱形杆的活塞。 响应于由操作员手动地或通过液压或气动动力而放置在活塞上的压力,活塞在圆柱形壳体内移动。 当活塞在圆柱形壳体中移动时,连接到活塞的杆响应于活塞的运动来回移动。 堵塞清除装置安装到排水阀或管道中的开口。 当通过气动动力操作时,手动或电磁阀控制阀将控制空气在圆柱形壳体中进出口的流动,从而在壳体内产生压力差,从而致动活塞(因此)的运动。 杆将从壳体延伸穿过开放式排水阀进入与排水阀流体连通的管道。 杆将打开排水阀或管道中的任何堵塞物,这阻碍了管道内部和排水阀之间的流体连通。 堵塞清除装置可以放置在管道中特别创建的开口中,在那里可能会发生可预测的堵塞。 堵塞清除装置可以被致动以延伸和缩回圆柱形杆,以便在堵塞清除装置安装在管道中的位置处发生堵塞。

    • A visually clear gel dentifrice comprising a polishing agent having a refractive index of about 1.41 to 1.47, a substantially water-insoluble noncationic antibacterial agent, an aqueous water-humectant liquid vehicle having a refractive index with about 0.02 refractive index units of the refractive index of the polishing agent and surfactant which is a sulfated polyoxyethylene alcohol sodium or potassium salt or a weight mixture of at least 3:1 to sodium or potassium lauryl sulfate with the sulfated polyoxyethylene alcohol or a weight mixture of about 1:3 to about 3:1 of sodium potassium lauryl sulfate with an N-acyl-N-alkyl taurate sodium or potassium salt. The visually clear systems have reduced formation of surfactant crystals when subject to cool temperature.

    • Dental implants made at least in part of a highly porous biomaterial such as porous tantalum for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a core formed of with a head portion having an abutment interface and a stem portion extending from the head portion. A porous tantalum sleeve is disposed about the stem portion and occupies a substantial portion of the implant/bone interface of the implant. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum sleeve to anchor the implant in position within the surrounding bone. Other embodiments of implants are provided, each implant including at least a portion thereof formed of porous tantalum for improved osseointegration.
    • 牙科植入体至少部分地制成高度多孔的生物材料,例如多孔钽,用于增强牙科植入物到骨骼的骨整合。 例如,提供了一种牙科植入物,其包括由具有邻接界面的头部形成的芯部和从头部部分延伸的茎部分。 多孔钽套管围绕茎部部分设置并且占据植入物的植入物/骨界面的大部分。 在植入植入物之后,骨组织可以骨整合到多孔钽套筒中以将植入物锚定在周围骨骼内的适当位置。 提供植入物的其它实施方案,每个植入物包括由多孔钽形成的至少一部分,用于改善骨整合。

    • A dental tray with a hydrophobic tooth whitening formulation where the tooth whitening formulation is substantially non-water soluble, and a method of using this dental tray to whiten the teeth. The tooth whitening formulation is primarily comprised of a hydrophobic polymer and a peroxide or a peroxide yielding compound. Preferably the hydrophobic polymer is the condensation product of a silicone resin and an organosiloxane. The dental tray is formed to encompass the front and the rear surfaces of the teeth. The dental tray is comprised of a thermoplastic or thermoset polymer. The teeth whitening formulation is placed into the dental tray and the tray placed against the teeth to be whitened. This is for a sufficient period of time to at least partially whiten teeth. This can be a period of time from about 0.5 hour to 2 hours or more. The substantially non-aqueous tooth whitening formulation is effective over a longer period of time since it is not significantly diluted or removed from the dental tray during the treatment time.
