Title: Praf toothbrush
Inventor: AKRAM ASHFAQ
IPC: A46B11/04
Filed: 1999-09-16
Abstract: For the use of toothbrush to clean the teeth, it is recommended that the head of the toothbrush should be placed beside teeth with the bristle tips at a 45 degree angle against the gum line. Sodium Fluoride or mouth wash are used to fight cavities, tartan and many other gum diseases. In PRAF Toothbrush, rectangular head with rounded edges contains bristles in five rows. They are classified as:      Bristle of outer row.      Bristles of intermediate row.      Bristle of central row. Bristles of all rows Do not have the same length. Instead, inclined cutting of bristles making 45 degree angle with horizontal plane is the unique characteristic of PRAF toothbrush as shown in figure 1 & 2.  Tuft of each row is not rounded end. Instead, it has Tapered End Which is 2nd important characteristic of PRAF toothbrush as shown in figure 4.     In PRAF toothbrush, there is passage for flow of sodium fluoride/mouthwash through micro holes located on Head around the bristles. The passage runs along neck and handle. The flow of Sodium fluoride/mouthwash through head of brush is the 3rd unique feature giving this tooth brush a NEW PRODUCT as shown in figure 6 & 7.

Furthermore, in order to accommodate the typical variety of conditions experienced by most users of an electric dry shaving system, whether the system is being employed by men or women, it has been found that the hair trimming assemblies are preferably able to be placed in at least three alternate positions quickly and easily by the simple movement of a single button or switch. In this way, the varying contours of an individual skin surface are easily accommodated and a smooth, comfortable, close shave is realized.
Patent CA-2318745-A1 (CA)
Inventor: EASTMAN DONNA
IPC: A61K47/48
Filed: 1999-06-07
Abstract: This invention relates to novel multibinding compounds that bind to potassium(K+) channels and modulate their activity. The compounds of this invention comprise 2-10 K+ channel ligands covalently connected by a linker or linkers, wherein the ligands in their monovalent (i.e., unlinked) state bind to one or more types of K+ channel. The manner of linking the ligands together is such that the multibinding agents thus formed demonstrate an increased biologic and/or therapeutic effect as compared to the same number of unlinked ligands made available for binding to the K+ channel. The invention also relates to methods of using such compounds and to methods of preparing them. The compounds of this invention are particularly useful for treating diseases and conditions of mammals that are mediated by K+ channels. Accordingly, this invention also relates to pharmaceutical compositions comprising a pharmaceutically acceptable excipient and an effective amount of a compound of this invention.
