    Abstract: Method and apparatus for controlling a hydraulic press having a row of hydraulic cylinder/ram assemblies for applying pressure in a workpiece of elongate form. The pressure of one cylinder/ram assembly adjacent one end of the workpiece is controlled in dependence upon the ratio of the length of the end portion of that workpiece over the length of the zone covered by that one cylinder/ram assembly.

    Abstract: A machine for flattening junked automobiles includes a relatively lightweight but rigid horizontally extending rectangular flattening head mounted for up and down movement over a rigid, comparatively lightweight horizontal flattening bed, with such movement being effected by hydraulic rams mounted at the corners of the generally rectangular flattening head. The head may be lifted enough to accommodate, between the head and the bed, one or more flattened automobiles plus one automobile to be flattened, so that a plurality of automobiles may be flattened between unloadings. The flattening mechanism is mounted on a highway trailer, and vertically disposed hydraulic rams force the head downwardly on their retracting stroke so that the height of the rams, and consequently the height of the overall unit, will be at a minimum, within Federal and State maximum highway transport height limitations, when the head is in its downmost position. In one form of the invention, the hydraulic cylinder bodies are attached to the flattening head and the remote ends of the piston rods are secured to the vehicle. In a modified form, the hydraulic cylinders are fastened to the vehicle and the remote ends of the piston rods are secured to the flattening head.

    Abstract: A device for driving in translatory motion the pressing element of a press, comprising a plurality of double-acting rams having their rods operatively connected to said pressing element said rams being hydraulically connected in series to each other, so that the driving of the piston of the first ram by a pressure fluid causes the rams to be fed by each other and the simultaneous sliding motions of their pistons, and means to keep constant the volume of hydraulic fluid contained in the front chamber of a ram and in the rear chamber of another ram with which it is connected.
