  • Patent number: 4556139
    Abstract: This bill accepting device comprises a bill discrimination section for discriminating whether an inserted bill is true or not, an escrow section capable of retaining a bill accepted by the bill discrimination section as a true bill and returning the retained bill, a stocker section for storing the bill accepted by the bill discrimination section as a true bill, and passage switching means for causing a bill passage in the bill discrimination section to communicate selectively either with the escrow section or with the stocker section. The passage switching section normally communicates the bill discrimination section with the escrow section to enable an inserted bill to be retained in the escrow section in a state in which the bill can be readily returned. When the escrow section has become full, the passage is switched so that the inserted bill is guided from the bill discrimination section to the stocker section.

  • Patent number: 4545505
    Abstract: An electronic control circuit for carbonated beverage dispensing machines employs the low voltage AC supply for the solenoid dispensing valves as a source of clipped, balanced ac which is applied to one or more water-imersed sensors. One sensor senses ice mass size and the other senses carbonated water supply level. The balanced ac prevents electroplating by the sensors. Peak detector circuits associated with the sensors produce dc control signals whose levels increase and decrease respectively as the control shut-off point is reached. These dc control signals are applied to Schmitt circuits, the output of one of which is used to control the carbonated water supply pump and the other of which inversely controls the refrigerant compressor. In addition, the balanced ac signal is used to clock a counter which is held at full count.

  • Patent number: 4543969
    Abstract: A coin sorter apparatus is provided for sorting coins by denomination using coin thickness as the discriminating parameter. The apparatus comprises a rotating disk located proximate a stationary disk. The rotational movement of coins on the rotating disk carries them into the region between the two proximate disks. Wherein a first selected are of ridges and recesses on the stationary disk surface manipulates the radial position of at least one denomination of the coins to a predetermined radial position using thickness as the discriminating parameter. A second selected area of ridges and recesses of the stationary disk receives the rotating coins carried on the rotating disk after the foregoing radial manipulation by the first selected area and radially releases rotating coins located at the predetermined radial position, thus allowing the coins to exit the region between the two disks at a particular location along the periphery of the stationary disk.
