Abstract: In a post-mix beverage dispenser a heat conducting plate assembly couples the bottom wall of a carbonator tank to the side walls of beverage concentrate storage tanks for the bi-directional transfer of heat therebetween. The cold temperature of the carbonator tank including an ice bank therein chills the concentrate to help achieve a suitable serving temperature of a finished drink. The higher temperature of the concentrate helps warm the bottom area of the carbonator tank in the region of an outlet opening to preclude freezing of carbonated water in the outlet opening.

Abstract: A drive system for side-by-side piston pumps connected to beverage concentrate containers in a post-mix beverage dispenser system is described. An electric motor rotates a drive shaft in either a forward or reverse direction for the selective actuation of one or the other of the piston pumps. First and second hollow shafts are concentrically disposed around the drive shaft, one hollow shaft being mechanically coupled through a cam and lever arrangement to each of the piston pumps. Free-wheeling clutches are provided between the drive shaft and each of the respective hollow shafts such that one hollow shaft is coupled to rotate with the drive shaft in the forward direction of rotation of the drive shaft and the other hollow shaft is coupled to rotate with the drive shaft in the reverse direction of rotation of the drive shaft.

Abstract: A disk brake arrangement in a motorcycle equipped with a wheel supported unilaterally at a wheel guide member whose wheel hub is connected with the wheel spokes, with a support hub rotatably supported relative to the wheel guide member as well as with a brake disk; the brake disk is thereby also provided with a brake disk hub which is clamped-in between the support hub and the wheel hub by way of a central connection.
