  • Patent number: 4809775
    Abstract: A pipe cutting tool especially adapted to cut the interior of in-the-hole (I-T-H) drill pipe to allow subsequent removal of the pipe above the cut. Due to blasting damage, long sections of I-T-H pipe, otherwise in good condition, cannot be removed because the damaged section prevents the removal of the entire drill string. The tool is adapted to receive power from an external source and includes a frame, a pivoted motor and cutter, and an actuator for pivoting the motor.

  • Patent number: 4801100
    Abstract: A rotary batch-type grinding mill for processing powder is provided with an improved system for discharging material under seal from the atmosphere. The discharge system comprises a sealable collection chute having a banana-like configuration secured on the mill shell at an outlet port in the shell and extending substantially parallel to the circumference of the shell, a grate which prevents discharge of the grinding media from the mill during unloading of material from the mill and an elastomeric faced sealing plate which covers the grate during operation of the mill. The sealing plate is operated from outside the sealed system so that discharge from the mill can be effected without breaking the seal and the sealing plate is so disposed that in the open position it does not interfere with the flow of powder out of the mill.
