  • Patent number: 4483204
    Abstract: An improved power absorption device of the general Prony brake design is capable of either applying to a rotating shaft either a fixed force or a force proportional to its rotational speed or for measuring mechanical power transferred to a rotating shaft by a prime mover. A stator shaft aligned with the rotating shaft is sealed within a cylindrical drum which is coupled to the rotating shaft and rotated thereby. A hydraulic system actuates a plurality of pistons in radially outward directions so as to frictionally engage the inner surface of the rotating drum. The resulting heat build-up is transferred through the finned, high-heat transfer lateral walls of the drum to water in a tank in which the rotating drum is located. Brake lubrication is provided by a closed lubricant circulation system within the rotating drum capable of providing efficient, uniform lubrication of the brake surfaces.

  • Patent number: 4459880
    Abstract: A process for fabricating a cross rolling die is disclosed. A flat wooden cross roll tooling model blank cut to the specified die dimensions is milled by a conventional milling machine to produce a pre-form blank in accordance with the desired cross roll die surface. A face cast of the thus contoured wooden model blank, or a negative impression, is then made which, in turn, is used to make a positive cast of the wooden model blank. A series of closely spaced cuts parallel to the axis of roll is then made in the wooden model blank and the positive cast of sufficient depth to provide radial flexibility in each of these pieces. The model blank is then divided into segments for separate mounting on the cross roll die mounting plates, with each segment mounted separately so as to cover approximately 315.degree. of the full 360.degree. displacement of the cross rolling machine.

  • Patent number: 4454920
    Abstract: A tillage system includes forward and rear sets of widely spaced discs and a set of plow points. The discs in the forward set are mounted at spaced intervals so as to leave alternate strips of worked and unworked soil of substantially equal width. Each disc of the rear set is mounted in a strip of soil left unworked by the forward set to complete the working of the top soil. The plow points are located in the furrows of one of the sets of discs (preferably the rear set) to permit some deep plowing. The working depths of the points and discs are independently adjustable. The system is designed for operation at high speed to provide complete coverage of the soil with minimal double working by the discs. It permits deeper penetration by the discs and a controlled amount of deeper plowing by the points while leaving a finished contour which is substantially free of ridges and furrows.

  • Patent number: 4437624
    Abstract: A positioning reel for suspending a body, such as a lightweight tool, at any vertical position within the limits of the suspension cord length is disclosed. An adjusting screw which regulates a clutch-type tensioning brake permits the supporting force of the positioning reel to be set to equalize the weight of the suspended body such that little effort is required to lower the suspended body. With the downward external positioning force removed from the suspended body, it remains in its present position. The suspended body can be easily raised by applying an upward external force equal to slightly more than the weight of the suspended body. When raising the suspended body, a clock-type coil spring actuates a spool within the positioning reel for retracting the suspension cord. A spring-type override clutch permits reeling in the suspension cord while bypassing the tensioning brake. With the upward external force removed from the suspended body, it will again remain in its present position.
