  • Patent number: 4498350
    Abstract: A shift mechanism (66, 68, 70, 72) for shifting a member (22, 22A', 22B, 27C) for performing an operation at a preselected one of at least two spaced-apart operating positions. The mechanism comprises a threaded screw (10, 10A, 10B, 10C) that is rotated about its central longitudinal rotational axis ("C") by a motor (14, 14A, 14B, 14C) to move a drive nut (12, 12A, 12B, 12C) in opposite axial directions therealong relative the particular direction the shaft is rotating and causes the drive nut to compress a resilient biasing means (20, 20', 20A, 20A', 20B, 20B', 20C, 20C') which is adapted to urge the member (22, 22A', 22B, 27C) to the particular position in a preloaded condition such that the operation is able to be performed by overcoming any resistance incurred in performing the operation or upon removal of the resistance upon the occurance of an event enabling the operation to occur.

  • Patent number: 4493224
    Abstract: Disclosed is a mechanism for manually shifting gears of a transmission from a remote operating station control lever. The mechanism features a rotatable slideable member having a protuberance that extends through an opening in the transmission casing and is adapted to move rail members within the transmission for engaging the gear combinations desired. The slideable member is preferably connected to the control lever by flexible cables such that movement of the lever along one axis causes the slideable member to rotate so as to position the protuberance adjacent the rail member desired. In one embodiment the slideable member is pivotally mounted to a rotatable member which is preferably connected to the control lever by a flexible cable such that movement of the control lever along a different axis causes the rotatable member to rotate which causes the slideable member to slide along a defined path and move the rail member to which the protuberance is adjacent.

  • Patent number: 4492636
    Abstract: Disclosed is a process for removing foreign matter and tramp oil from a continuously recirculating metal working fluid. The process includes the use of saturated dissolved air flotation which, contrary to prior belief, is able to effectively remove the foreign matter and tramp oil in a quiescent manner with little or no foaming and without removing or harming any emulsions present in the metal working fluid. The process further includes the use of water soluble organic cationic and anionic polyelectrolytes where desired to flocculate the foreign matter and tramp oil to enhance their removal from the metal working fluid and a process by which the formation of foam at or near the surface of the metal working fluid being clarified is able to be suppressed.

  • Patent number: 4469120
    Abstract: Disclosed is a fluid pressure and signal controller (60) that is adapted to regulate a fluid pressure regulator (16) by means of rotation of a cam (24) in response to rotation of a shaft. The controller is additionally provided with means for generating signals at one or more predetermined positions on the cam by movement of an output member (48) that is in contact with a profiled surface (40, 40') of a body member (38) which in turn is caused to move in response to movement of a cam follower (42) that is in contact relationship with the cam. Means are provided such as threads (51) are provided for adjusting the rotative position of the body member with respect to the position of the cam follower to account for any change in the initial position of the cam member and to enable more than one of the signal generation means to be positioned at different locations about the cam.

  • Patent number: 4425931
    Abstract: Disclosed is a speed controlled fluid pressure regulator that is adapted to provide a fluid pressure control signal for use in a variety of control functions in response to changes in rotational speed of an object such as a rotating component of an internal combustion engine. The regulator is controlled by a speed biasing mechanism that utilizes a counterbalancing arrangement between a biasing means and a component that is moved by a centrifugal weight assembly in response to changes in the rotational speed of the object being monitored to position a valve of the regulator with a high degree of sensitivity which in turn enables the regulator to provide the output fluid pressure control signal from a fluid pressure source in a highly effective manner.
