  • Patent number: 4292508
    Abstract: Equipment for use in a trading system in which a bonus is given to a customer selected comprises a plurality of stores, such as counters, which are fed successively so that they are filled successively depending on the feeding rate and the capacities of the counters. When a store is filled, feeding is stopped and the bonus appropriate to the filled store is made available to a subsequent customer initiating a transaction. The filled store is emptied and feeding to the stores is resumed until another store is filled and the appropriate bonus is paid. A modification may include a random selector which scans the stores and makes the bonus available if a full store is selected. Means may be provided to display the running bonus and the customer point at which the bonus is payable.

  • Patent number: 4292509
    Abstract: An indicator for tape running direction and tape remnant amount is provided which comprises a ring counter clocked by a sensing pulse corresponding to the rotation of a take-up reel, a counter for providing count value corresponding to the period of the sensing pulse, comparators each for comparing the count value of the counter with reference data, gate circuits which are connected to the output circuits of the ring counter and controlled by the comparators, and a display unit which receives the output pulses of the gate circuits and includes a plurality of decimal points for indicating the tape running direction and the tape remnant amount. The output signals of the ring counter are shifted corresponding to the tape running direction. The number of signal circuits of the output pulses led from the gate circuit to the display unit depends on the result of the comparison by the comparators.

  • Patent number: 4291221
    Abstract: A digital semiconductor circuit has at least two circuit parts, each including a counting chain having identical memory cells which serve for receiving and transmitting digital information. The counters are controlled by a common clock. The counter of the first circuit part is coupled to a signal generator which emits a digital pulse upon reading a predetermined, specific digital state of the counter of the first part. The signal generator emits a digital pulse which is superposed on a clock pulse so as to amplitude modulate the same. The modulated clock pulse is detected by a signal recognition circuit of the second circuit part to trigger a correction signal generator which sets the counter of the second circuit part to a predetermined count.

  • Patent number: 4283620
    Abstract: A diagnostic arrangement is disclosed for determining the length of arbitrary shift registers not exceeding a maximum length. Knowledge of this length is an essential prerequisite for data manipulations by means of shift registers. Concerned are the reading of shift registers and the display of the contents stored in them, as well as the writing of arbitrarily selectable patterns into said shift registers.The arrangement proper includes circuitry connected to the shift register or test object for generating a test shift pattern of the length L.sub.max +K, with K.gtoreq.2, which pattern is made up of a defined bit configuration, for example, only binary ones, with a defined transition at the end facing the test object and which is shifted through the test object. Also provided is storage means of length L.sub.max +K, which is connected to the output of the test object and which, as the test shift pattern is shifted, accommodates the information of the length L.sub.x of the test object and the part L.sub.

  • Patent number: 4279014
    Abstract: An arrangement for dynamically translating virtual address into absolute or physical addresses of items of data. Each virtual address includes a segment table number, a segment table entry, and a segment page number. Segment descriptors are stored in a central memory. The address of a particular segment descriptor may be calculated from the segment table number and the segment table entry. From the segment descriptor, a unique identification termed a logic page number may be calculated. The logic page number permits pseudo-associative access to a table containing a number of entries proportional to the number of physical pages of the main memory, allowing the physical address to be determined.

  • Patent number: 4276468
    Abstract: An electric home appliance which is automatically controllable with use of a sensor such as temperature sensor or humidity sensor. Variations in terms of analogue quantities given by the sensor are converted to variations in the number of pulses by an oscillator connected to the sensor and comprising an astable multivibrator or the like. The number of pulses is counted by a counter, the gating time of which is determined for example by divided frequency of a commercial power supply. The control system is inexpensive to make and has high reliability.

  • Patent number: 4276467
    Abstract: An apparatus for receiving and handling empty beverage containers. The empty containers may be received either individually or in cartons upon a moving conveyor. An alignment mechanism separates the containers and moves them to one side of the conveyor. A switch arrangement senses cartons, so that the system can process cartons of empty containers in a different manner than individual empty containers. The containers, whether individually or in cartons, pass through an illumination station wherein they interrupt illumination falling upon a row of photocells. Output signals from the photocells are transmitted to identification circuitry together with clock signals generated in synchronism with the movement of the conveyor. The identification circuitry generates registration signals, which are used to compute value of the containers being received. A paddle mechanism shifts the cartons to a separating station, which forwards properly filled cartons to a storage area.
