Abstract: Among other things, in one aspect, an apparatus comprises features to enable mounting first and second jetting assemblies on a frame. The features comprise first and second alignment datums pre-fixed with respect to the frame for establishing respective positions of the first and second jetting assemblies, when mounted, so that at least some of the nozzles along a length of one of the jetting assemblies have predetermined offsets relative to at least some of the nozzles along a length of the other of the jetting assemblies, and an opening exposing all of the nozzles along the lengths of the first and second jetting assemblies are exposed to permit jetting of a fluid onto a substrate.

Abstract: A fuel system with a fuel tank having at least one opening into an interior of the fuel tank, and an electrically operated vent valve having an inlet communicated with the interior of the fuel tank and an outlet for venting fuel vapor from the fuel tank. The vent valve is movable in response to an electric signal between an open position allowing fuel vapor through the outlet and a closed position to restrict fluid flow through the outlet. A controller is operably communicated with the vent valve to control application of an electric signal to the vent valve and thereby control at least in part the movement of the vent valve between its open and closed positions. In one embodiment the controller is responsive to a fill level in the fuel tank to control the position of the vent valve and thereby the fill level attained within the fuel tank.

Abstract: Apparatus for training and testing persons for pouring predetermined quantities of liquid in the mixing and preparation of beverages. The apparatus includes a frame having a backwall and spaced apart support members for supporting a plurality of transparent graduated tubular containers. Each container is marked with graduations indicating incremental quantities of liquid correlated with indicia printed on the containers and/or on the frame adjacent to the mouths of the respective graduated containers. The apparatus is particularly useful in training and testing persons for free pouring beverages and beverage ingredients in the retail liquor service industry. A testing method using the apparatus includes positioning the apparatus so that the trainee cannot view the containers during test pouring operations. Test scores are recorded on a score sheet having printed facsimiles of the graduated containers.
