Abstract: In connection with a beverage dispensing machine, an automatic self-fill control apparatus for the machine for controlling the filling of the liquid tank, which liquid tank is fed with a combination of water and a concentrate syrup adapted to be mixed with the water within the tank. A sensor member is disposed in the tank in a position so as to be responsive to the rise and fall of liquid in the tank. Pump means are provided adapted to pump the syrup to the tank. Control of water flow to the tank is also carried out. The sensor member has a low probe for detecting a low predetermined level of liquid in the tank and a high probe for detecting a high predetermined level of liquid in the tank and adapted to respectively generate low and high probe signals.

Abstract: A connector is disclosed wherein a plug member includes a plurality of plug pins rigidly mounted therein. Each of the plug pins includes a support portion with a torsion element and a contact member of elongated cross-section extending therefrom. The connector also includes a socket member including a plurality of rigidly mounted sockets of appropriate dimensions for receiving contact members of the plug member. Each of the sockets includes a throat section with an internal, laterally elongated cross-section, disposed a predetermined distance along the length of the socket. When the torsion elements are relaxed, the contact members are oriented to have their cross-sections misaligned relative to the throat sections of the sockets so as to place the aforementioned torsion elements in torsion when the contact members are forced into the throat sections of corresponding sockets as the plug and socket members are mated.
