摘要： A digital wipe device is provided for lenses and similar articles which consists of a pair of sheaths in which the first sheath fits on a thumb of a hand and the second sheath fits on a finger of the hand. An interconnecting flexible member is connected to and extends between one side of each of the sheaths. A plurality of wiping sheets are connected in a stacked manner to an underside of the interconnecting flexible member and the sheaths, so that the outermost wiping sheet can be used to clean the lenses and similar articles between the thumb and finger and than torn away when soiled to expose a fresh clean wiping sheet for further use.

摘要： A method for selecting a flame retardant for a polymer comprises using cross polarization and magic-angle sample spinning techniques to record well resolved .sup.31 P and .sup.13 C nuclear magnetic resonance spectra of the polymer before and after ignition; recording .sup.31 P and .sup.13 C NMR spectra of the combination of polymer and a known flame retardant before and after ignition; characterizing the chemical and physical changes that occur in the flame retardant and the polymer upon ignition and thereby determining the chemical basis by which the known flame retardant is operating and using that knowledge to select another flame retardant that will be effective for use with the polymer.
摘要翻译：选择聚合物阻燃剂的方法包括使用交叉极化和魔角样品纺丝技术来记录聚合物在点燃之前和之后的良好分辨的31P和13C核磁共振谱; 在点火之前和之后记录聚合物和已知阻燃剂组合的31P和13C NMR光谱; 表征在点火时在阻燃剂和聚合物中发生的化学和物理变化，从而确定已知阻燃剂在运行的化学基础，并使用该知识来选择将有效用于聚合物的另一种阻燃剂。

摘要： A mail box is shaped like a post which is to say it has a housing in the shape of a rectangular prism. The letter box pivots at its bottom front from the top of the housing. The amount the letter box pivots outward is adjustable and a weight on the rear of the letter box tends to pull it closed. The letter box is particularly adapted for urban and suburban placement where the mailman delivers the mail from a vehicle or where the mailman does not deliver the mail to a door side box.
摘要翻译：一个邮箱形状像一个柱子，就是说它有一个矩形棱柱形的外壳。信箱从其外壳的顶部向下摆动。信箱向外转动的量是可调节的，信箱背面的重量往往会被关闭。信箱特别适用于城市和郊区的位置，邮寄员从车辆发送邮件，或者邮递员不将邮件发送到门侧盒子。

摘要： An insulating bolt is disclosed herein for use in supporting signs on walls comprising a hollow threaded shaft having a channel disposed on the shaft to receive a grounding strap which is laid in the channel. The end of the grounding strap conforms to the end of the shaft of the bolt for engaging into the end of an armored cable thus providing grounding means from the sign back to the power source. A slide locking nut having a raised shoulder for sliding in the channel is provided for positioning and holding the bolt in place.
摘要翻译：本文公开了一种用于在墙壁上支撑标志的绝缘螺栓，其包括中空螺纹轴，该中空螺纹轴具有设置在轴上的通道，以接收铺设在通道中的接地带。接地线的末端符合螺栓轴的端部，用于接合到铠装电缆的端部，从而提供从标志回到电源的接地装置。提供具有用于在通道中滑动的凸起肩部的滑动锁定螺母用于将螺栓定位并保持在适当位置。
