Abstract: The present invention discloses colon cleansing compositions for treating chronic constipation. The colon cleansing compositions comprise mixtures of Calcium Polycarbophil and flaxseed powder and the mixtures are preferably in tablet form. A method for using the colon cleansing compositions for treating chronic constipation is disclosed. The preferred method is to orally masticate and swallow two tablets after each meal and two tablets before bedtime, followed by drinking a sufficient quantity of fluid to activate the colon cleansing compositions in a person's digestive system leading to colon cleansing in a period of less than 72 hours. After the initial colon cleansing, a dosage of the colon cleansing composition is preferably orally masticated and swallowed at least one of: after breakfast, after dinner, and before bedtime; followed by drinking a sufficient quantity of fluid to prevent further constipation.

Abstract: An earth-boring bit has hardfacing that has multiple grades and an overlapped portion. One of the layers is of a different grade than the other so as to provide more wear resistance. The other provides more toughness than the wear resistant layer. The more wear resistant layer has a greater volumetric density of carbide particles. The greater density is primarily achieved by using a majority of the particles of smaller dimension than in the less wear resistant hardfacing. The overlapped portion may be on an outer or gage end of the outer row of teeth.
