  • Patent number: 5232649
    Abstract: To extract a liquid from a workable mass of material a first force is applied to the material in a first direction. A second opposed force is applied to the material within or slightly downstream of a liquid-extraction location. These opposed forces tend to compact the material to extract the liquid. The extracted liquid moves out of the liquid-extraction location along a path which extends generally transverse to the direction of the first and second forces. Third forces are applied to the material along the path in a direction generally opposite to that taken by the exiting liquid to prevent the material from traversing the path but to permit the liquid to exit. The first, second and third forces form a pinch point on the material within or slightly downstream of the liquid-extraction location to substantially obviate liquid flow countercurrent to the direction of the first force.

  • Patent number: 5228323
    Abstract: An improved flaring tool includes the usual plurality of expandable die blocks retained by a U-shaped frame. A clamping screw is treaded through a clamp block which is rotatably mounted between the legs of the frame at its open end. The screw is movable toward and away from the die blocks to clamp or unclamp tubing between adjacent die blocks. A conical flaring tip is movable against the end of a clamped tubing for flaring same. The clamp block's axis of rotation is perpendicular to the direction of movement of the die blocks and the screw. The improvement comprises a facility which locks the clamp block against rotation when the screw is aligned with the die block and their direction of movement. The locking facility prevents unintentional rotation of the clamp block as the screw is rotated to clamp or unclamp the tubing, but may be manually overcome to intentionally rotate the clamp block.
