    Abstract: A method and apparatus for the coring of poles comprising a tubular drill casing having a cutting bit at one end. The drill casing is rotated and the pole and casing are moved axially relative to one another to core the pole. During the coring operation, compressed air is directed into the drill casing to eject chips cut by the drill. The rotation and relative axial movement of the drill casing and pole are correlated to control the size of the chip so that the chips are carried out between the outer periphery of the drill casing and the outer periphery of the cored hole. A special drill bit for the coring operation is also disclosed.

    Abstract: A method of making a corrugated medium which permits the use of scrap from a corrugating plant. It includes the steps of forming a web of substantially non-bonded fibres, passing the web through a nip formed by a pair of heated corrugating rolls to corrugate the web and press the fibres into intimate bonding contact thereby to consolidate the web in corrugated form, thereafter applying liners in the conventional manner.

    Abstract: A PREALLOYED IRON-COPPER POWDER WHICH HAS HIGH COMPRESSIBLIITY AND SHRINKS UPON SINTERING IS PREPARED BY MELTING A CHARGE OF IRON AND COPPER, ATOMIZING THE CHARGE WITH WATER JETS UNDER PRESSURE, FURTHER COMMINUTING THE PARTICLES IF DESIRED, AND SUBJECTING THE FORMED POWDER TO A HEAT TREATMENT BETWEEN 1400*F. AND 1800*F. IN A REDUCING ATMOSPHERE FOLLOWED BY A CONTROLLED COOLING.
