  • Patent number: 4848556
    Abstract: A low power coin discriminator detects and identifies the denomination of a coin to activate a parking meter, telephone, or vending machine device. Initially the device is in a low power, dormant state. Insertion of a coin into the discrimator trips a switch which produces a wake-up pulse which turns on a microprocessor. The coin falls upon a piezoelectric element, a signal from which causes the microprocessor to activate a photoelectric sensor. The coin moves through the photoelectric sensor which determines the net cross-sectional area of the coin. The microprocessor samples the output of the photoelectric sensor to detect the minimum light incident upon the sensor at the point of maximum eclipse of the light beam. The microprocessor also samples the output of an integrator which integrates the output of the piezoelectric element to produce a numerical value proportional to the mass of the coin.

  • Patent number: 4842162
    Abstract: Apparatus and method for dispensing fluid materials wherein the fluid is discharged from a nozzle at a rate controlled by a metering valve having a seat and a stem moveable with respect to the seat to modulate the flow. A servo-actuator connected in a feedback control loop is used to position the valve stem with respect to its seat in accordance with a control signal. The control signal is derived in accordance with the difference between a driving signal representing a desired flow rate and the sum of a pair of feedback signals. One feedback signal represents the actual flow rate while the other feedback signal is correlated to both the relative velocity and position of the stem with respect to the seat. The position-dependent velocity signal is generated by a transducer comprising a magnet and a coil influencable by the field of the magnet as the magnet and coil move relative one another.

  • Patent number: 4832654
    Abstract: The disk shaped articles or coins to be sorted are conveyed by an entrainment belt on a base plate in conveying direction along a guide rail. Dependent on their diameter, the coins are separated out of the conveying path at respectively one of the sorting stations. The outward transfer ensues by a high-speed sorting belt into whose sphere of influence the coins respective proceed when, as a consequence of their diameter, they are lifted off from the base plate at one side due to their inherent motion in conveying direction, being lifted off by means of a wedge-shaped deflection element. The sorting belt then withdraws the coin to be transferred out of the conveying path under high acceleration, so that it proceeds into a collecting shaft. Such as apparatus functioning with an exclusively mechanical arrangement allows a high sorting speed given a compact structure.

  • Patent number: 4821919
    Abstract: Apparatus for stacking conical objects includes right hand and left hand side walls which are joined by divergent walls to define a tapering horizontal cross-section column in which the spacing between the opposite walls is shorter than the length of any one of the conical objects. The conical objects can be placed manually in the top of the column 1 but only in a given orientation (thanks to the tapering horizontal cross-section of the column) and only when hooked on a retaining finger projecting into the column through the side wall. The conical object at the top of the stack thus settles into an inclined orientation which it retains when the retaining finger is released to drop the cone down the column, thanks to an inertia brake to retard the wider diameter end of the falling cone and preventing the cone from becoming vertical. The retaining finger at the foot of the column releases only the bottom cone and allows any cones above it to become indexed downwardly into the bottom-most position.

  • Patent number: 4822019
    Abstract: A cut sheet feeder feeds out a cut sheet from a first paper cassette when a bidirectional pulse motor for driving paper feed rollers rotates forward and from a second paper cassette when the bidirectional pulse motor rotates reversely, and can suppress feed-out of the cut sheet from the wrong paper cassette when the pulse motor starts to rotate. The feeding of the cut sheet from the wrong paper cassette is suppressed by stopping the motor at a predetermined phase. A first memory stores the predetermined phase and a second memory stores the current phase. A controller compares the contents of the first and second memories and applies a drive pulse to the motor until the contents of the memories coincide. A loop is formed in the cut sheet prior to the comparison of the contents of the memories to permit the motor to be rotated in the proper direction.

  • Patent number: 4821862
    Abstract: A coin-box placed adjacent to a television receiver is interposed in the path of a signal input line that supplies program signals to the receiver. Signals on some program channel (the "free" channels) are permitted to pass through the coin box at all times. The purpose of the coin box is to require payment for the reception of programs on certain other selected frequency channels (the "pay" channels). One or more band rejection filters (frequency traps) are utilized within the coin box to normally prevent reception of the pay channels. A bypass circuit, controlled by a relay, permits the pay channels to be received during time periods that have been paid for. The coin-box is lockable for security purposes and contains a timing circuit, a relay, and other controls. The selection of pay channels as well as the various control parameters may be adjusted at will by the proprietor of the establishment in which the television set is located.
