Abstract

The apparatus positions loads which are located at both ends of a binary piston adder. Such positioning is effected by clamping either end of the adder to the machine frame and allowing the adder to position the load at the other end.

The apparatus positions loads which are located at both ends of a binary piston adder. Such positioning is effected by clamping either end of the adder to the machine frame and allowing the adder to position the load at the other end.

Load 16 is mounted within frame 300 such that it is free to move vertically up or down. Frame 300 is fixedly mounted on plate 301, which rests on the surface of machine frame 302. Compression spring 310 is attached by pin 311 to frame 302 and by pin 312 to sliding plate 301, thus constantly tending to force plate 301 to the right. A braking mechanism 315 and 325...330 is operable to prevent movement of plate 301.

A pneumatic binary adder mechanism includes individual adding pneumatic actuators 25, 26 and 27 and positioning pneumatic actuators 28 and 29. The pneumatic actuators are held in axial alignment by a cylindrical carrier 340, but are free to move longitudinally. Each of the pneumatic actuators 25 and 26 includes two pistons and a dividing wall between them. The other pneumatic actuators include only a single piston. Orifice 350 of actuator 25 opens into the cylinder formed with the piston that is connected to shaft 30. Orifice 351 opens into the cylinder formed with the piston connected to shaft 31. Likewise, orifice 352 of actuator 26 opens into the cylinder formed with the piston of shaft 31. Orifice 353 opens into the cylinder formed with the piston of shaft 32. In the case of all other actuators, the orifice provided opens into the single cylinder.

Actuators 25, 26 and 27 form a binary adder. The piston of actuator 25 connected to shaft 30 is movable a distance of one binary unit. The piston in actuator 25 connected to shaft 31 is movable a bina...
