Abstract: A cutting element for a drill bit used in drilling subterranean formations is formed with an internal chamber or passage for the flow of drilling fluid therethrough. A substrate having at least one internal passage, and prior to attaching the table thereto, the at least one passage is filled with a removable substantially incompressible filler material. Attachment or bonding of the table to the substrate under high temperature and high pressure is accomplished without significant distortion of the shape and size of the passage. The filler material may be a crystalline salt such as sodium chloride or halite, which are removable by dissolution in water, or may be boron nitride or a volcanic material such as Pyrofolyte material which are mechanically removable.

Abstract: A stamping punch of a punching apparatus including a grip member provided with crosspieces formed between long grooves on side walls of a rectangular parallelepiped, and a plurality of punch members which are formed integrally with the grip member. The respective punch members are arranged in parallel to one another. A plurality of holes are defined on a punch holder. A large amount of adhesive is contained in the gap between joining surfaces when the grip members of the stamping punches are inserted and secured into the respective holes. Accordingly, the positional accuracy of the punch member is improved, the accuracy of the hole defined through a workpiece is improved, and it is possible to eliminate any fear of occurrence of defect in shape. Further, the rigidity of the punch member can be improved, the stripper is prevented from application of unbalanced load, and the punch is easily exchangeable.

Abstract: A method for producing longitudinally welded helically corrugated metal tubing, wherein a metal strip pulled from a strip supply is formed into tubing with a longitudinal slit, the longitudinal slit is sealed by welding and the corrugation is produced by a corrugation tool that is supported eccentrically and at an angle to the tubing axis, is freely rotatable in a rotationally driven corrugator head, and rolls off the surface of the tubing. The metal strip as well as the uncorrugated metal tubing are advanced by a feed device that is provided between the welding point and the corrugation unit. A second feed device (8) engages the corrugated tubing (7) directly behind the corrugation unit (6), and the feed rate of the second feed device is slower than the forward feed rate of the corrugated tubing (7) which results from the pitch of the corrugator disk and the rotational speed of the corrugator head.

Abstract: Disclosed an integrated refrigerator evaporator having a plurality of pipes and fins which is manufactured by injection molding with plastics. According to the present invention, pipes and fins are molded by means of at least one plastic plates, and a heat exchanger is formed by molding the pipes and fins in a series of nullSnull shape. A first bending section formed by the heat exchanger, which is molded in a series of nullSnull shape, is inserted into a mold main body to manufacture a header cap. A first header cap is manufactured by injecting melted plastic material body into the mold main body under the state of covering a mold cap. The first header cap is engaged with a first header main body comprising the first header cap and the refrigerant inlet and outlet. The refrigerator evaporator according to the present invention results in a relatively lower product cost than the evaporator composed of a metal substance as well as a high recyclability.
