  • Patent number: 4487052
    Abstract: A device for removing irregularities in or enlarging a buried duct comprises a cylindrical housing (10) corresponding approximately in diameter to the required diameter of the duct, a plurality of tapered leaf members (14) pivotally attached at their rear ends to the front of the housing, and a conical wedge (18) driven by an axial hydraulic ram (12) mounted inside the housing (10). In operation, the apparatus is drawn through the duct with the leaf members (14) in a retracted position in which they form a tapered nose portion, until an irregularity in the duct causes resistance to forward movement. The ram (12) is operated to force the leaf members outwardly against the wall of the duct to remove the irregularity. The leaf members (14) are then retracted as the apparatus is drawn forward to the next obstruction. The apparatus is particularly intended for preparing damaged sewers prior to fitting an inner, lining pipe.

  • Patent number: 4468665
    Abstract: A downhole digital power amplifier comprises a device which, through digital means, provides a sinusoidal, variable frequency, variable power and variably phase-shift modulated output for the transmission of data from a downhole sensor arrangement to an uphole receiver. Selection and variation of frequency, power and modulation are made through digital inputs. The device provides these functions at extra low frequencies (ELF) low-to-high power output, and varying phase-shift keying.

  • Patent number: 4453334
    Abstract: Disclosed is a fishing lure designed so that the fishing line passes through an aperture in a spinner support wire which connects the body to the spinner before passing through or being attached to the body. The aperture acts as a pivot point, and variations in tension in the fishing line cause the body and the spinner to pivot about the aperture.

  • Patent number: 4423622
    Abstract: Method of an apparatus for pressure testing and cleaning pipe in which one or more pipes are secured to a treatment manifold (31). The or each pipe is then filled through one end with low pressure water via an inlet (40) in the manifold (31), the other end of the or each pipe including a self-bleeding valve (52) which closes once the air within the pipes has been evacuated. The pressure is held for a predetermined time and the pressure sensed by a visual gauge (14) and a paper read-out (16) so that any pressure drop indicative of failure is noted. The pressure is then released, the valve (52) removed and the high pressure water at a pressure between 500-8000 psi introduced through jets (35) to wash the pipes which are then dried with compressed air before removal.
