  • Patent number: 4267437
    Abstract: An exposure control device is disclosed which has an extremely high accuracy as compared with the prior art, the error range being within a one-eighth step. For such a highly accurate control of exposure time, a value of exposure time to be determined is converted to a binary code of n bits, of which the lowest one bit is weighed one-eighth step. Based on the decimal number corresponding to the upper m bits of the binary code, the frequency of the control signal is adjusted and is used in reading out the lower (n-m) bits of the same binary code, whereby the period of actuation of the shutter is determined.

  • Patent number: 4266120
    Abstract: A numerically controlled machining center has a tool magazine, automatic tool changer, workpiece shuttle, and a workpiece magazine which holds enough workpieces for operation by the machining center for an entire shift of approximately eight hours. The numerical controls are programmed to perform predetermined machining operations on each workpiece, in turn, and to replace each finished workpiece with a fresh workpiece at the end of each machining program. A proximity switch is mounted on the machining center for checking tools to detect broken or incorrect tools. The tools are positioned adjacent to the proximity switch and are rotated while the output of the proximity switch is counted for one complete rotation of the tool to determine the number of radially extending teeth on the tool. If the tool has too few or too many teeth, thus indicating a broken or incorrect tool, it is replaced by another tool of the same type.

  • Patent number: 4257108
    Abstract: A pulse generator for generating pulse groups with desired widths and relations (spacings) within and between the groups up to extremely high speeds and with a time accuracy of the order of nanoseconds e.g. in radar applications. It is purely digital and operates on a control frequency which may be derived from an internal crystal oscillator or may be externally supplied. The generator is divided into two main units, a first unit for determining the spacing of the pulse groups, and a second unit controlled by the first unit for determining the pulse widths and controlling pulse generator means. Different time space numbers and pulse widths numbers may be programmed into PROM memories of said units and may be selected by the same set of operating mode signals. The time spacing may also be optimized by means of an external computer controlling a further PROM holding information which may be combined with the time distance PROM information.

  • Patent number: 4255651
    Abstract: A method of countng a succession of sheets passing along a flow line (the sheets being normally spaced but including some overlapping sheets), comprises determining the position of a double thickness in relation to the total length of the sheet in the flow direction. A count of two is added to the count of sheets if the double thickness is found to be symmetrically placed in relation to the total length of the sensed "sheet" and has a length consistent with the amount by which two single sheets would have to overlap to have a total length equal to the sensed "sheet" length. If these requirements are not met, depending on the results of the measurements either a count of one is added or an error signal is generated.

  • Patent number: 4254328
    Abstract: Apparatus for dispensing a preset monetary amount of product, such as fuel, sold by volume and for use with a dispenser which calculates and displays a continuously increasing cost of the delivery has a number of selector buttons which relate to units of cost and which when selected set an appropriate number into a counter. The counter is coupled to the display, and the count is decremented by one for each unit cost of product actually delivered. During delivery of the first unit a store calculates the difference between a unit cost and the cost of a small predetermined volume, which volume is required to be delivered slowly to end the delivery and avoid under- or over-delivery due to mechanical or fluid inertia of the dispenser. When the counter indicates the final unit preselected is being delivered, a comparator compares continuously the cost displayed for that unit and the stored difference and when they are equal the delivery rate is slowed for the final predetermined volume.

  • Patent number: 4253014
    Abstract: In a postage meter which can be set to imprint a selected value of postage on individual mail pieces, two counters are typically provided for accounting purposes. One counter is an accumulating counter into which the postage value imprinted during each operation is added. The second counter is settable by the Postal Service to the amount of postage purchased by the meter user. As postage is imprinted by the meter, the value of the postage is subtracted from the second counter. Thus, this counter continuously indicates the amount of postage that remains available for imprinting. The meter of the present invention additionally provides an operator resettable counter to indicate the total value of postage imprinted on any group of consecutive mail pieces. The function and operation of the original counters are completely separate and unaffected by the present invention.

  • Patent number: 4251722
    Abstract: A pulse generating device for speeding-up the rate of a pulse train from N to N+n wherein each of the pulses in the N+n pulse train is synchronized with the immediately preceding pulse in the original N pulse train. A count-up counter is reset upon each original pulse and counts up from zero, at frequency F/N+n, up to the following original pulse. A count-down counter is loaded with the contents of the count-up counter when the following original pulse occurs or when the output pulses occur with the exception of the last pulse in the interval when the time interval between said original pulses includes several generated output pulses, and is decremented at frequency F/M up to zero. A variable presettable counter provides the count-down counter with frequency F/M when each original pulse appears or when the output pulses appear with the exception of the last pulse in the interval when the time interval between the original pulses includes several output pulses.
