Abstract: An adjustable suction pipe assembly for use in a liquid transfer system including at least first and second pipe members wherein one end of the second pipe member includes a seal member and wherein the second pipe member is frictionally insertable within the first pipe member, the seal member being slidably adjustable along the length of the first pipe member. The seal member is oriented such that a portion thereof extends away from the outside diameter of the second pipe member and sits in a space formed between the engagement of the first and second pipe members. If the fluid level within the supply tank is below the location of the seal member, atmospheric air which may enter the first pipe member at a location above the seal member will force the seal member against the inside diameter of the first pipe member thereby further sealing the connection therebetween.

Abstract: The electronic nutating disc flow meter is suitable for measuring different liquids with varying viscosities. This meter is best suited for measuring medium viscosity fluids of 10 to 450 centipoise. This flow meter includes a microprocessor to correct for the nonlinearity of fluid flow. The memory in the microprocessor contains three calibration curves with accompanying lookup table information. CAL A is preset at the factory for thin viscosity fluids. CAL B is preset at the factory for medium viscosity fluids and CAL C can be field calibrated. The calibration curves can be plotted with up to five points per curve.

Abstract: A self-leveling series type hydraulic system including boom and bucket valves which separately control boom and bucket cylinders and a flow divider valve positioned in the exhaust flow path from the rod end of the boom cylinder. The flow divider valve splits the flow sending a portion of it to the cap end of the bucket cylinder so as to maintain the bucket in a level condition during raising of the boom with the remaining flow returning to the control valve downstream of the boom valve along with the return flow from the rod end of the bucket cylinder which is also returned to the control valve downstream of the boom valve whereby the bucket valve can be separately actuated concurrent with the boom valve and supplied with oil so as to override the self-leveling function if desired.

Abstract: A self-leveling series type hydraulic system with a float position including boom and bucket valves which separately control boom and bucket cylinders and a flow divider valve positioned in the exhaust flow path from the rod end of the boom cylinder. The flow divider valve in one position splits the flow sending a portion of it to the cap end of the bucket cylinder so as to maintain the bucket in a level condition during raising of the boom with the remaining flow returning to the control valve downstream of the boom valve whereby the bucket valve can be separately actuated concurrent with the boom valve and supplied with oil so as to override the self-leveling function if desired. The flow divider valve having a second position which bypasses all of the flow from the boom cylinder to reservoir when the boom control valve is in a float position.
