    • The amount of electrically conductive material in the bottom floor lining of a conventional aluminum reduction cell is reduced by using a non-conductive lining material in its place. The non-conductive material separates the remaining electrically conductive regions from the sidewall linings of the cell and preferably confines the electrically conductive material to the "anode shadow" region of the cell floor. In another embodiment joints between the conductive and non-conductive regions are positioned such that they are covered by cell freeze (solid electrolyte) during operation of the cell. This prevents liquid cell contents penetrating the joint and adversely affecting the cell lining, thus shortening the life of the cell. The non-conductive material preferably comprises a particulate alumina mixture made up of large shapes which firmly compact together and smaller particles which fill the remaining voids. Optionally, the mixture may be bonded together with amorphous alumina, in which case the mixture can also be used for cell wall linings. The linings can be used in reduction cells of conventional design and reduces undesirable magnetohydrodynamic effects as well as pollution hazards caused by conventional carbonaceous cell linings.
    • 传统的铝还原电池的底层衬里中的导电材料的量通过在其位置使用非导电衬里材料来减少。 不导电材料将剩余的导电区域与电池的侧壁衬里分开,并且优选将导电材料限制在电池板底板的“阳极阴影”区域。 在另一个实施例中,导电区域和非导电区域之间的接头被定位成使得它们在电池工作期间被细胞冷冻(固体电解质)覆盖。 这防止液体细胞内含物穿透关节并且不利地影响细胞衬里,从而缩短细胞的寿命。 非导电材料优选包括由大的形状组成的颗粒状氧化铝混合物,其牢固地压实在一起,并且填充剩余空隙的较小的颗粒。 任选地,混合物可以与无定形氧化铝结合在一起,在这种情况下,混合物也可用于细胞壁衬里。 衬里可用于常规设计的还原电池,并减少不期望的磁流体动力学影响以及由常规碳质电池衬垫引起的污染危害。

    • A tape-reinforced tubular vascular graft formed of sintered fluoropolymer(s), such as expanded, sintered PTFE. The graft includes a base graft and a reinforcing tape applied thereto. The tape may be spirally wrapped about the graft or spirally wrapped into a tube about a cylindrical mandrel and then applied to the exterior of the graft. Radial shrinkage of the combined base graft and tape, or of the reinforcing tape tube, renders the vascular graft subsequently radially enlargeable by more than 5%, without tearing or breaking of the reinforcement tape layer of the graft. Radially enlargeable grafts of the present invention may be combined with various types of stents or anchoring systems, to form endovascular graft devices which are transluminally insertable and implantable within the lumen of a host blood vessel. Alternatively, radially enlargeable grafts of the present invention may be implanted by way of traditional surgical graft implantation techniques, without any radial enlargement of the graft at the time of implantation, so as to take advantage of the improved strength properties and suture-holding properties of the radially-shrunken tape-reinforced grafts of the present invention.
    • 由烧结的含氟聚合物形成的带状增强的管状血管移植物,例如膨胀的烧结PTFE。 移植物包括基底移植物和施加于其上的加强带。 胶带可以围绕移植物螺旋地包裹或螺旋地缠绕在围绕圆柱形心轴的管中,然后施加到移植物的外部。 组合的基底移植物和带或增强带管的径向收缩使血管移植物随后径向放大超过5%,而不会撕裂或破坏移植物的加强带层。 本发明的可径向扩大的移植物可以与各种类型的支架或锚定系统组合,以形成血管内移植装置,其可平移插入并且可植入主体血管的腔内。 或者,本发明的径向可放大的移植物可以通过传统的手术移植物植入技术植入,而在植入时没有移植物的任何径向扩大,以便利用改进的强度性质和缝线保持性能 本发明的径向缩小的带状增强移植物。

    • A novel brake assembly is provided for a bicycle. The assembly is composed of an arrangement of a pair of brake pads each connected to a rod member in turn guided for axial movement by a base fixed on the bicycle frame. A bifurcated control cable actuates wedge members causing movement of the pads against a wheel rim. Return springs on the rod members cause the assembly to return to the original non-braking position in response to release of the control cable. As an option, a second wedge action can be incorporated that is activated by the frictional forces generated from the contact of the brake pads with the wheel rim. The second wedge action is limited by a mechanical stop within the brake assembly to prevent jamming of the brakes.
    • 为自行车提供了一种新颖的制动组件。 该组件由一对制动衬块组成,每个制动衬块连接到杆件上,并依次由固定在自行车车架上的底座引导轴向运动。 分叉的控制电缆致动楔形构件,引起垫抵靠轮缘移动。 响应于控制电缆的释放,杆构件上的返回弹簧使组件返回到原始的非制动位置。 作为一种选择,可以并入第二楔形动作,该动作由通过制动片与轮缘接触产生的摩擦力而被激活。 第二楔形作用受制动组件内的机械止动限制,以防止制动器卡住。
