Abstract: A flexible skirt for preventing debris such as dirt and rust, for example, from accumulating on the seal between the piston and cylinder of a hydraulic vehicle lift assembly. The skirt comprises an essentially flat piece of material cut or formed such that it has an inside perimeter of substantially the same diameter as the piston diameter and an outside perimeter of a larger, predetermined diameter. Two free ends extending from the inside to outside perimeter include releasable attachment means allowing the skirt to be wrapped around and encircle the piston with the two ends then attached back together. A series of spaced, through holes are provided in the skirt in the area between the inside and outside perimeter for passing bolts therethrough which have been removed from the underlying retaining ring which holds the seal in place.

Abstract: Apparatus for pumping, mixing and dispensing two liquids includes a conduit for tapping a remotely located container containing a first concentrated liquid such as methyl alcohol. A housing contains a second liquid for diluting the first liquid and a pump for pumping the two liquids at equal rates into a static mixing apparatus. The amount of first liquid entering the mixer may be decreased as desired via a needle valve located on a conduit leading back to the remotely located container. The mixer includes an internal cavity having a plurality of 90.degree. hollow elbow joints randomly positioned therein such that the two liquids pass therethrough and combine into a resultant mixture. The mixture may be dispensed to a second remote location as desired.
