    • A hinge for an orthopedic splint has two plates hinged for pivotal movement relative to each other and a detent engageable for locking the plates at a selected angle to each other, and a spring urging the detent into engagement. The detent is protected in a recessed guideway against operation with the unaided hand to discourage tampering with the splint settings by the patient fitted with same, but is retractable with a pointed tool inserted in the recess or a removable screw threaded in the detent as a finger hold. The screw may also pass through the detent and if tightened against an underlying plate keeps the detent disengaged to facilitate adjustment of the splint. The hinge allows left and right hand angular settings of the splint to either side of a zero angle for ambidextrous use of the splint, and radial tabs with directional markings are provided as visual indicators of the angular setting of the splint hinge.
    • 用于矫形夹板的铰链具有两个铰链以相对于彼此枢转运动的板,以及可接合以相互选定的角度锁定板的棘爪,以及促使棘爪进入接合的弹簧。 棘爪在凹进的导轨中受到保护,以防止手部的操作,以防止装配有夹具的夹板设置被篡改,但是可以用插入凹部中的尖锐工具或作为手指螺纹连接在棘爪中的可移除螺钉来收缩 保持。 螺钉也可以穿过止动器,并且如果紧固在底板上,则使制动器脱开以便于夹板的调节。 铰链允许夹板的左右角度设置为零角度的任一侧,以便双向使用夹板,并且具有定向标记的径向凸片被提供为夹板铰链的角度设置的视觉指示器。

    • A feeding device for use by persons with limited or no use of their arms, wherein a spoon is mounted on supporting and counterbalancing levers and is associated with a mouth-piece in such a manner that the user can manipulate the spoon to lift food from a dish, can then place the spoon on a fixed support and then adjust the spoon to a position for convenient eating of the food. The spoon mounting includes an adjustable support for a counterbalancing spring. All the parts are mounted on a flat base which is adapted also to support the food dish.

    • The cathodic protection system of a concrete structure (22) uses sacrificial anodes such as zinc, aluminum and alloys thereof embedded in mortar. A humectant is employed to impart high ionic conductivity to the mortar in which the anode is encapsulated. Lithium nitrate and lithium bromide and combinations thereof are preferred as the humectant. The anode (10) is surrounded by a compressive, conductive matrix (12) incorporating a void volume between 15% and 50% to accommodate the sacrificial corrosion products of the anode. A void space of at least 5% of the total volume of the anode (12) may be provided opposite to the active face of the anode. Synthetic fibers such as polypropylene, polyethylene, cellulose, nylon and fiberglass have been found to be useful for forming the matrix. A tie wire is used to electrically connect the anode to the reinforcing bar.
    • 混凝土结构(22)的阴极保护系统使用嵌入砂浆中的牺牲阳极,例如锌,铝及其合金。 使用保湿剂来赋予阳离子被包封的砂浆高的离子电导率。 作为保湿剂,优选硝酸锂和溴化锂及其组合。 阳极(10)由包含15%至50%之间的空隙体积的压缩导电基体(12)包围,以适应阳极的牺牲腐蚀产物。 阳极(12)的总体积的至少5%的空隙可以与阳极的活性面相对设置。 已经发现合成纤维如聚丙烯,聚乙烯,纤维素,尼龙和玻璃纤维可用于形成基质。 使用连接线将阳极电连接到钢筋。

    • The galvanic cathodic protection of steel embedded in concrete structures is enhanced by the utilization of a flexible composite anode assembly containing a sacrificial anode member. The anode member is at least partially covered by a matrix comprising an ionically-conductive material. The conductive material includes at least one electrochemical activating agent such as a mixture of lithium bromide and lithium nitrate and a compressible water-retaining mineral such as a phyllosilicate mineral. The presence of this mineral in the matrix increases the current delivered by the anode, thereby resulting in a greater level of cathodic protection, and a longer effective service life of the anode. Exfoliated vermiculite is a preferred phyllosilicate mineral and is present in an amount of between about 2% and about 15% by weight, based on the total weight of the matrix.
    • 通过利用包含牺牲阳极部件的柔性复合阳极组件,增强了嵌入在混凝土结构中的钢的电镀阴极保护。 阳极构件至少部分被包含离子导电材料的基体覆盖。 导电材料包括至少一种电化学活化剂,例如溴化锂和硝酸锂的混合物以及可压缩的保水矿物如页硅酸盐矿物。 这种矿物在基体中的存在增加了阳极传递的电流,从而导致更高水平的阴极保护和更长的阳极使用寿命。 剥离的蛭石是优选的页硅酸盐矿物,并且基于基质的总重量以约2重量%至约15重量%的量存在。
