摘要： A device for aiding and encouraging a child to brush his or her teeth regularly. The device is provided with a pair of nonrotatable shafts each of which mounts seven rotatable blocks shaped like a molar tooth, each block representing either the morning or night of a particularly day during which a child should brush his teeth. The front surface faces of the blocks form a frowning mouth with dirty teeth, while the rear surface faces form a pattern of a smiling mouth with white teeth after all of the blocks have been rotated 180 degrees. Each block is rotated to expose a portion of the smile and to remove a portion of the frown after each tooth brushing in the morning and evening of each day.

摘要： An end clip for attachment to the ends of finite strips of mesh-clad RFI/EMI shielding strips. A clip attachment is formed of a thin strip of metal, such as stainless steel, with hook-like flanges at opposite ends for securement to the edge margins of a mounting strip member of U-shaped cross section. The clip passes over the top of and partially compresses the end extremity of a tubular mesh-clad core strip mounted on the U-shaped strip. The end clip not only improves the appearance of the shielding strip end, but prevents possible snagging of the exposed tube end during use. A pointed tab, pressed out of the clip material, penetrates the core strip and resists accidental removal of the clip.
