Abstract: A failsafe hydraulically operated tool clamping system for use on press brakes comprising a series of pressure/spring actuated piston control units or actuators. These actuators are attached to the press brake tool clamps by a plurality of spaced bolts which extend through the actuators and the fixed and slidable members defining the tool clamps. Compression or Belleville springs urge the fixed and slidable clamp members into tight engage with the tool set punch and die. To open the clamp, pneumatic or hydraulic pressure is applied against the actuator piston thereby overcoming the force exerted by said springs and releasing the punch and die. Both tool set members remain firmly gripped within respective tool clamps in the event of system pressure loss thereby assuring failsafe retention thereof. The lower or bed clamp assembly comprises an L-shaped slidable member and a fixed member with a slot for receiving one leg of the L-shaped member.

Abstract: The compression air seal for containing air between equipment racks and electronic modules is described incorporating a metal base having a slot opening and an inclined or tapered upper surface with respect to the lower surface, a double layer of elastomeric material having two hardness values one upon the other in enclosing the opening and a coating of low-friction material over the upper elastomeric material to facilitate low friction when an electronic module having a tapered surface is slid over and compresses the seal.

Abstract: A heat dissipating container for electrical components immersed in a liquid dielectric in one chamber and for electrical components surrounded by an air dielectric in another chamber. A flexible bladder serves as a common wall with the liquid dielectric chamber and an air filled recess that is in communication with the air filled chamber to compensate for expansion and contraction of the liquid.
