Abstract: A method for dejuicing grapes uses a dejuicer comprises a closed tank provided with a dejuicer grid and an inflatable membrane in the tank which is pressurized to force juice out of the harvested grapes through the grid. A conveyor in the tank remove the dejuicer grapes from the tank. Harvested grapes are placed in said tank and the juice is allowed to flow naturally. The inflatable membrane mounted in the tank is then pressurized to force out further juice through the grid and the juice is collected from the tank. The membrane is then depressurized and the tank is emptied by actuating the conveyor.

Abstract: A high speed machine for cold forging screws, rivets, and the like comprises a frame supporting a die-carrying head thereon reciprocates a punch carrying slide, shears having a fixed and a movable blade, and a bar stock shearing device including a linkage effective to transmit at least part of the movement and energy of the punch carrying slide to the movable blade and convert the reciprocating motion of the slide into a reciprocating motion of the movable blade.
