摘要： A heat exchanger (38) is provided which may be used in a mass transfer device (20), such asn an oxygenator or a dialyzer. The heat exchanger comprises a core (40) formed of a corrugated metal having a high thermal conductivity. Each of the corrugations of the core comprises substantially parallel side walls (70, 72). A first fluid, such as blood, is introduced onto the outside of the core. A second fluid, such as water, is introduced into the inside of the core. The first and second fluids will be in heat exchange relationship with each other and the flow of the fluids is substantially uniform resulting from the substantially parallel side walls of the corrugations. The core is formed by providing a flexible metalhose, annealing the flexible metal hose, compressing the annealed hose and expanding the compressed hose to a length that is substantially less than its original length but greater than its length during compression.

摘要： A brush for home use such as washing cars and patios. The brush includes a body having a plurality of dependent bristles and defining a first compartment for a receiving soap and a second compartment for receiving rinse water. The body also includes an elongate tube partially defining each of the compartments. The first compartment has an outlet for providing soapy water to the bristles while the second compartment has an outlet for providing rinse water. A spool valve is slidable back and forth in the tube with the valve having a tubular wall defining an axial bore open to the conduit and an opening extending through the wall for communicating water to either of the compartments. Seals are carried by the spool valves flanking the opening to provide watertight seals between the valve and the tube. The brush also includes a thumb switch for reciprocating the valve along a linear path among a soap position, a rinse position, and an off position where water is supplied to neither of the compartments.
摘要翻译：家用刷子，如洗车和露台。刷子包括具有多个依附刷毛的主体并且限定用于接收肥皂的第一隔室和用于接收冲洗水的第二隔室。主体还包括部分限定每个隔间的细长管。第一隔室具有用于向刷毛提供肥皂水的出口，而第二隔室具有用于提供冲洗水的出口。滑阀可以在管中来回滑动，其中阀具有限定到管道开口的轴向孔的管状壁和延伸穿过壁的开口，用于将水连通到任一隔室。密封件由开口侧面的滑阀承载，以在阀和管之间提供水密密封。刷子还包括一个拇指开关，用于沿着在肥皂位置，漂洗位置和关闭位置之间的线性路径使阀门往复运动，其中水被供应到两个室。

摘要： Apparatus and method for duplicative notching of the serration edge on a key blank according to the serration edge of an existing key serving as a templet. An axially movable key edge notching punch is controlled by the templet for punching a notch in the serration edge of the key blank corresponding to a notch in the serration edge of the templet when the punch is driven toward the key blank. The key blank and the templet key may be supported in a cassette which is indexible relative to the punch. The cassette and the notching mechanism are especially advantageous for notching the serration edges of key blanks carried by wallet size plastic cards.
摘要翻译：根据用作寺庙的现有密钥的锯齿边缘，在密钥坯料上重复刻划锯齿边缘的装置和方法。一个可轴向移动的钥匙边缘切割冲头由凸模控制，用于在冲头朝向钥匙坯件方向移动时，冲压出与坯料锯齿形边缘相对应的凹槽对应的钥匙坯料锯齿边缘中的切口。钥匙扣和木扣钥匙可以支撑在相对于冲头可分度的盒中。卡带和切口机构特别有利于切割由钱包尺寸的塑料卡携带的钥匙坯料的锯齿边缘。
