Abstract: An apparatus is disclosed for use in a control system having a control point adjustment and a throttling range adjustment, the apparatus having, for example, a first dial having a throttling range pointer attached thereto, a second dial having throttling range indicia and control point indicia thereon, a control point pointer for cooperating with the control point indicia, a shaft connecting the first dial to the control point adjustment and a locking screw for locking the first and second dials together so that the first and second dials rotate in unison for changing the control point of the system and for unlocking the first and second dials so that the first dial can be rotated to change the control point to compensate for any adjustments in the throttling range of the control system.

Abstract: Pneumatic logic system.The logic chain is established by juxtaposition of logic modules each of them being provided with a selecting organ having at least two positions allowing to modify the circuit diagram.Advantageous system for the sequential control of machines by pneumatic way.

Abstract: A distributor board or panel for compressed air monitoring systems including an integral die-cast distributor housing and a plurality of flow detectors. The housing has a longitudinal opening and surrounding structure to which the flow detectors are mounted for registry with a longitudinally extending common compressed air line through respective air supply lines which extend at right angles from the common compressed air line, and to respective air outlet lines which have cable connections associated therewith. The individual air supply lines and air outlet lines are also formed in the distributor housing. In each air supply line there is mounted an automatic closing stop valve which can be opened by a control pin mounted within the respective flow detector.
