Abstract: This invention relates to operating mechanisms for hydraulic control systems and it is an object of the invention to provide an operating mechanism which is self-locking. The mechanism includes a bar which is slidable in a channel, one face of the bar being cut away to provide two inclined surfaces. Rollers are retained by springs in the spaces between the inclined surfaces and one side of the channel. A plate is also located between the bar and the said side of the channel and a control member serves to displace this plate along the channel. The arrangement is such that, when the plate is displaced in either direction, it pushes a respective one of the rollers towards one end of the bar, thereby allowing it to roll down the inclined surface. On the other hand, if a force is applied to the bar in either direction, a respective one of the rollers will move up the inclined surface and wedge against the side of the channel, thereby locking the bar in position.

The control system includes an enabling circuit for the control valve in series with a controlled switching device and a circuit for energizing a fuel igniting system.

Abstract: A cable rotator utilizing a hollow member having a pair of spaced openings communicating with its interior. A collar, having a first and second opening, permits passage of the hollow member through the first opening. The hollow member frictionally engages the sides of the collar's first opening, with a certain degree of slippage. The cable passes through the interior of the hollow member with a portion of the cable disposed to the exterior of the hollow member via the hollow member's openings and the second opening of the collar. Means for rotating the collar also rotates the hollow member, restraining rotation of the hollow member causes rotation of the cable.

The support brackets for the converter casting include cooling fluid passages across the outer ends thereof adapted to be sandwiched between the stock cooling fluid pump flow passages and the engine cooling passages.

Abstract: A fully rotary engine adaptable to internal combustion or operation from an external heat source is provided wherein a drum-like housing containing a plurality of roller vanes contacts the inner surface thereof with the contact being maintained by a cylindrical inner race. At each end of the housing a torque plate, having a centerline offset from that of the housing and vane guide grooves which control the distance between each pair of roller vanes, transmits the rotation of the roller vanes to an output shaft running through the center of the torque plates. Rotation of the output shaft is provided by alternately increasing and decreasing the distance between adjacent roller vanes through expansion and contraction of a contained gas or through combustion and exhausting of a fluid/air mixture.
