A table shear may include a clamp and a shearing mechanism, the shearing mechanism supported by the clamp. The shearing mechanism may include a fixed lower shear blade, a lower shear blade backup plate supporting the fixed lower shear blade, a moveable upper shear blade and a shear compression cylinder. The shear compression cylinder abuts the movable upper shear blade.

A micro-cavity liquid-phase shearing device for preparing quasi-two-dimensional materials includes a movable plate system, a fixed plate system, a feed liquid external circulation system, a driven gear system and a charging barrel. The movable plate system includes a movable plate unit and a driving gear. The fixed plate system includes a fixed plate unit and a support. A tank of the movable plate unit has a primary shear cavity, an annular micro-gap between a movable plate of the movable plate unit and a fixed plate of the fixed plate unit is defined as a secondary shear micro-cavity. The feed liquid, which flows outside the feed pipe through the liquid discharge port thereof, is primarily sheared in the primary shear cavity by the movable plate system, and then is secondarily sheared in the secondary shear micro-cavity by the movable plate and the fixed plate, and then returns to the charging barrel.

A control device according to some embodiments of the disclosure includes one or more motors directed by the control device to form whip(s) from a length of a cable by causing the cutting of the cable in accordance with specifications based at least in part on whip information. An interface communicates the whip information between the control device and a user device.

A miter saw is provided. The miter saw includes a table for supporting a workpiece; a fence located on the table; and a beveling arm for supporting a saw blade, the fence operatively connected to the arm to move the fence when the blade is beveled so that the blade does not contact the fence when the blade is moved toward the table. A method of locating a workpiece near a saw blade is provided. The method may include moving an adjustable section of fence near a path the saw blade will travel by beveling the saw blade; and moving a workpiece to contact the fence near the saw blade path.

A system, apparatus and method for cutting battery grids or plates from a continuous strip of a plurality of connected battery grids. The continuous strip moves toward a rotating cutter with at least two cutter blades with cutting edges equally circumferentially spaced apart and extending parallel to the cutter axis of rotation and a rotating cooperating anvil. The cutting edges and the anvil are rotated at the same tangential speed to cut in a nip between them a plate or grid from the continuous strip of connected grids. At a point upstream of the cutter, an electric signal indicative of each lug of the grid of the continuous strip moving past this point is used to control the speed of movement of the strip through the nip to cut a plate or grid from the continuous strip at a longitudinal speed which is essentially the same as the tangential speed of the cutting edges.
