Abstract: A cable plow having a chassis with a pivot arm having a first end pivotably connected to the chassis and a second end pivotably connected to a plow element characterized by an arrangement extending between the plow element and the pivot arm to resist pivoting of the plow element from a desired or rated plowing position in response to increased forces applied on the element. Preferably, the chassis is constructed as a sled which is adapted for plowing or laying cable on either land or beneath the water's surface.

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.
