Abstract: A router table assembly utilizing a steel plate table top penetrated by a stepped opening having slightly non-concentric round holes. A table top insert is received in the stepped opening, which insert is a round plastic disk having a ledge formed by a disk portion of smaller diameter which matches the smaller hole in the top and which smaller disk portion is slightly offset from the layer diameter portion. The disk is positioned in the top opening and is rotated approximately one-fourth revolution until the cam-like action of the non-concentric portion locks the disk in place. Jaw-like router base clamp mechanisms have plates adjustable to the size and shape of numerous router bases and can be positioned once, after which the router can be removed and remounted in exactly the same position if assured centricity in the table top.

Abstract: An impact screw-tightening apparatus is comprised of a main body and a controller. The main body includes a motor outputting pulsed drive output, a main shaft driven by the drive and connected to a screw to be tightened, and a torque detector detecting a change of torque applied to the main shaft. The controller includes a calculating section and a control section. The calculating section obtains frequency of impacts generated from a time that a bearing surface of the screw is in contact with a tightened object, on the basis of the signal from the torque detector. The control section cuts off a motive power source of the drive at a time that the frequency of the impacts becomes a predetermined value. Therefore, even if impact operation is executed prior to the contact of the bearing surface, the tightening force is accurately calculated by a rapid and brief calculation and control logic, and the dispersion of the tightening force at the cut-off time is decreased.

Abstract: A dual walled pipe string structure defines an annular cavity between the walls into which hard granules may be packed to oppose wall collapse when inserted to high pressure well depths. Segments of pipe thus constructed will reduce the heat transfer across the pipe string allowing for the conveyance of drilling mud from a surface cooler to a downhole tool. The rate of cooled drilling mud transfer to the tool may be controlled to match the heat transfer rates and the heat generated at the tool. To further oppose wall pressures inert gas at opposing pressure may be introduced into the interstices between the granules.
