| | | (...) I have created a pneumatic polarity reversor using four pneumatic switches. I did an analysis and my pneumatic multiplexor works as a hydraulic switch that does not have a free release. (URL) above picture contains two pneumatic multiplexers. (...) (21 years ago, 8-Apr-04, to lugnet.technic)

| | | | (...) I get the impression you've complicated things by putting different switches at different lever angles. My reverser idea puts the switch lever pivots 16mm apart, all in a line with 2-beams between: BSBSBSBSB along a beam of length 17 holes, so (...) (21 years ago, 8-Apr-04, to lugnet.technic)

My pneumatic mux that can act as a polarity reversor, can just as easily be used for an (...) (21 years ago, 8-Apr-04, to lugnet.technic)

| | | | (...) A XOR gate has two inputs, one with 1 switch and one with 4 switches. The 4-switch one is a standard reverser and the 1-switch one has the air supply on the middle and the two outer ports go to the input ports of the reverser (the middles of (...)

Mark Tarrabain's single switch AND gate has two individual pressure inputs; one forces the piston to (...) (21 years ago, 11-Apr-04, to lugnet.technic)

A bank of switches may be driven by one cylinder (1 or 2 switches), two cylinders (3-5 switches) or more (6 cylinders in the case of 9 switches in my octopus arm logic). The number of (...)
