Abstract: A post support includes a platform portion and an attached post portion. The end of the post portion distal to the platform portion is in a laterally and vertically spaced-apart relation to the platform portion. When the platform portion is buried adjacent to a stack wall with the post portion between the platform portion and the stack wall and with a fence or handrail post attached to the end of the post portion, a lateral load applied to the fence or handrail post is supported by the platform portion without damage to the stack wall.

Abstract: An improved control system for selectively clamping a die to a power press or similar machine by means of a plurality of hydraulically actuated clamps. Such hydraulically actuated clamps are provided for securing the opposed halves of the die to the bolster and ram of the press. The clamps are connected in alternating fashion to first and second fluid conduits for both the bolster and the ram. Each of the conduits is connected to a source of pressurized fluid. The first and second conduits on the bolster and the ram provide a safety redundancy feature in case one of the conduits on the bolster or the ram fails. Each of the conduits is provided with first and second pressure sensors. The first pressure sensors are each adapted to generate an electrical output signal when the pressure in the associated conduit falls below a first predetermined level.
