Abstract: A drill pipe mountable wellbore cleaning tool apparatus that enables attachment to a drill pipe joint having first and second connector end portions and a cylindrically shaped portion in between the connector end portions The apparatus includes a support sleeve that is mounted to the drill pipe joint in between the connector end portions. Centralizers are attached to the opposing ends of the support sleeve, with each centralizer overlapping a portion of the support sleeve. At least one locking clamp is attached to the cylindrical portion next to a said centralizer. The locking clamp prevents the support sleeve from moving longitudinally along the drill pipe joint.

Abstract: A biscuit or cookie and method of manufacture of same includes forming a quantity of unbaked dough into a shaped, unbaked dough piece. A network of lines comprising grooves is impressed into the upper surface of the unbaked dough piece, either in conjunction with or subsequent to forming of the dough piece. A major portion of the lines in the network are non-terminated lines which continue across the surface of the dough piece and intersect either the edge of the dough piece or another line, and a minor portion of the lines are terminated lines which end short of either the edge or another line at least at one end thereof. The shaped dough piece with the network of impressed lines is baked under such conditions as to increase its diameter by from one-tenth to one-half and to form superficial fissures along at least some of the impressed lines and at least in some of the areas of the upper surface of the dough piece upon which lines were not previously impressed.
