DEFINITION

Classification: 91/512

Condition is that of a load driven by a working member other than working member having its operation modified:

(under subclass 511) Apparatus wherein the external condition is the condition of the load driven by one of the working members.

(1) Note. If a force transmitting means driven by the working member is rigidly attached thereto the means is then considered to be a part of the working member. However, if the force transmitting means is movable relative to the working member, said means is then considered to be part of the load.

(2) Note. Placed in this subclass are apparatus having plural working members wherein the position of the load of one working member results in the control of the motive fluid for another working member when the working members are not relatively movable.
