In an installation for registering the serial numbers of firearms in a computer, a plurality of stations, each having a television receiver displaying the image of the serial number of a firearm being registered, and a unit operatively associated with the computer and providing a keyboard and a display screen next to the television receiver, with an operator assigned to each station, and each operator instructed first to produce, by selective manipulation of keys of the keyboard, a duplicate of ...

A programmable electronic calculator is provided having a manually operable annuity switch with begin- and end-position settings, enabling a user to specify the type of annuity calculation to be performed. When the switch is set to the begin position, the annuity calculation is performed with payments due at the beginning of each payment period; when the switch is set to the end position, the annuity calculation is performed with payments due at the end of each payment period. The annuity calcul...

A system for the automatic supervision of a multiplicity of machines in a manufacturing plant includes a set of transducer units individual to the respective machines for converting their operating speeds into binary data which are successively read out, under the control of a scanner sequentially activating respective couplers, to a tape puncher together with data identifying the machines and their operators. The punched tape is then fed to a computer which interprets the received data and pass...

In a credit checking system, a system monitor tests the communications link between counter units in outlying stores and a central location. The system monitor periodically sends Request signals over a telephone line to the central processing unit. In response to an unconditionally valid account number encoded by the system monitor and transmitted to the control processing unit (CPU), a valid signal is returned to the monitor. If this valid signal is not received, the counter units are switched ...

Each supply station has an assigned station number, and the respective carriages are positioned along both sides of an endless delivery belt for menu-component-receiving trays, and an electronic food service control is provided. Each carriage is divided into three sections with each section having three container areas therein with a respective signal lamp associated with each container area and mounted on a respective lamp arm, each lamp arm being associated with the respective section. Each se...

In a manufacturing facility a centrally located computer has information entered, using, a keyboard into memory, at an address determined by a department number. The information relates to part shortages or other manufacturing data, indicating the manufacturing responsibility of each department in the plant. On signal, the computer sends the data for each department, using the department number as the address, to a display control means at each department which stores the data relevant to that d...

A comparatively small electronic inventory control device for indicating the current stocks of goods, individually or in succession. The item numbers of the goods are selectively entered by push-button switches. New information for updating the stocks is entered by the same switches. Numerals for item number and the information are differentiated by separate manual switch means. A rotary memory means having addresses corresponding to the item numbers of the goods is used for storing and updating...

A computer-controlled warehousing stacker bin address memory system using clock signals, and comprising a keyboard or the like for introducing binary bin address data into the system and for issuing command signals and enable signals to a control circuit comprising a priority encoder and a preset read only memory. One set of shift registers, with digital display, is enabled to receive input address data. Thereafter, command and enable functions cause data from the display registers to be issued ...

A method is disclosed for reproducing in graphic form a marker defining the positional relationship of pattern pieces to be cut from sheet material in an automatically controlled cutting machine. The method employs the cutting table of the same automatic cutting machine that is used to cut the pattern pieces of the marker from layups of sheet material. The method is comprised of spreading a plotting material over the support surface of the cutting table on which the sheet material to be cut is n...

A battery-powered, hand-held, calculator employs MOS/LSI calculator circuits to perform arithmetic and financial calculations. Data and commands are input to the calculator from a keyboard having shift key to double the functions of selected keys. A 15-digit, seven-segment light emitting diode (LED) display serves as the output for the calculator. The calculator circuits include a read-only memory circuit in which the algorithms for performing the arithmetic and financial calculations are stored...
