Abstract: A mechanism for preventing the skew of a cut paper sheet, for use in a duplex printing machine or a paper reversing mechanism having a switchback mechanism for switching the cut sheet backward from its trailing end by reverse rollers and so on immediately after the cut sheet subjected to the printing at a printing portion is once discharged onto a reverse plate by paper discharge rollers and so on, the mechanism comprising: a plurality of paper guides formed on a surface of the reverse plate of the switchback mechanism so as to limit the lateral movement of the cut sheets of several kinds in the direction of the width thereof, the paper guides being arranged in a manner to correspond respectively to the widths of the cut sheets of several kinds to be discharged onto the reverse plate, the distance between each two paper guides for guiding a respective one of the cut sheets being slightly greater than the width of the corresponding cut sheet, and the paper guide for guiding the wider cut sheet being higher tha

Abstract: Apparatus for stacking sheets comprises a collecting bin with a front stationary abutment and a rear limiting element adjustable to various sheet size ranges. A first deflecting roller, adjustable in the entrance direction of the sheets and mounted on a rear limiting element, provides support for a transport belt transporting the sheets. The rear limiting element is mounted on a support which is movable in the entrance direction by means of two parallel threaded spindles rotatable by a stepping motor. A second deflecting roller which is associated with the outer side of the transport belt facing the sheet stack is arranged on the support, whereas the first deflecting roller is located on the inner side of the transport belt. Adjacent to the second deflecting roller, a stationary deflecting roller is arranged such that the transport belt is guided along an S-shaped path.

Abstract: Apparatus for removing medication units from a card dispenser comprising a card on which medication units are secured in pockets formed in a flexible sheet material disposed in the card and sealed by a rupturable covering element thereof, has a base member upon which the card dispenser is supported. The base member has a body portion with a series of elongated channels in its upper surface defined by parallel extending ribs. A roller with a handle is rotatably rolled along the upper surface of the card dispenser while bridging the channels to press downwardly the medication units and cause the rupturable covering element to be severed and the medication units to drop into the channels.

Abstract: An apparatus and method for storing and dispensing comestibles, such as ice cream, has a cabinet defining an interior for holding a plurality of stacked ice cream containing magazines. A refrigeration system for cooling the interior of the cabinet below the freezing point of the ice cream is connected thereto. An X-Y picker assembly is positioned in the cabinet interior to transport ice cream from the selected magazine without heating the selected ice cream container or any other ice cream containers stored therein. The ice cream is carried by the X-Y picker assembly to a dispensing opening in the cabinet from which it can be accessed by the consumer. A nonvolatile information storage device is associated with the plurality of magazines and contains product characteristic information therein related to the flavors of ice cream in the magazines. A mapping system maps switch closures from product selection switches with the product characteristic information.

Abstract: A supporting member is fixed to the moving element of a toroidal type linear motor, the support member being maintained a predetermined distance from a stationary element to maintain a predetermined annular air gap between the stationary and moving member. The supporting member may comprise a plurality of rollers which are rotatably provided on the top and bottom of the moving element, the rollers being so arranged as to be radially spaced from the stationary element. The distance between the rollers and the stationary element is less than the distance between the stationary and moving elements.

Abstract: A coin discrimination apparatus discriminates authenticity and a denomination of a coin by oscillation magnetic fields of high and low frequencies in a low frequency band in which generated magnetic fluxes allow a coin to pass therethrough. A first oscillation coil for generating an oscillation magnetic field of a low frequency and a reception coil are arranged at coin contact and coin non-contact surfaces, respectively, of an inclined coin path to face each other. A second oscillation coil is arranged on the coin non-contact surface to be separated from the reception coil by a predetermined distance in a coin rolling direction and generates an oscillation magnetic field of a high frequency.
