Abstract: A dispenser assembly is provided with a lever, a cam, and a seal. The lever is configured to be pulled by a user a first distance to a first position. The lever is further configured to be pulled by the user a second distance to a second position. The cam is configured to provide a first resistance to pulling the lever when the lever is pulled over the first distance to the first position. The cam is further configured to provide a second resistance to pulling the lever when the lever is pulled over the second distance to the second position. The seal is configured to be moved in response to movement of the lever and the cam. The seal partly opens a spout of the drink maker when the lever is in the first position and fully opens the spout when the lever is in the second position.

Abstract: A two channel universal device for advanced protection from a short circuit current which evaluates a rate-of-change of current in a supply feeder and compares the current in the supply feeder and the current in load phases generating a differential signal in such a way that in normal conditions, when the load is running or starting, the differential signal is virtually zero. The differential signal and the rate-of-change of current in the supply feeder are compared with the settings of the protective device. If both the value of the rate-of-change of current and the value of the differential signal simultaneously exceed their settings, after an adjustable time delay, the device produces a signal to open the circuit. The existence of two conditions necessary to initiate the trip signal to cause the circuit to open ensures the reliable operation of this device and provides a feasible fast protection scheme.
