A program controlled data processing system which includes two data manipulation units generally operated in parallel. The two data manipulation units, however, by design react differently in the execution of certain program order words. The system includes a circuit arrangement which compares data generated by the two data manipulation units and generates comparison signals indicating the identity or lack of identity of the compared data. The comparison signals are utilized in the detection of ...

A circuit arrangement for program selection comprises a sensor operated integrated circuit having a plurality of non preferential sensor circuits, the sensor circuits being connected to a program voltage source through an R.C. circuit and the sensor circuit to be made preferential has a further resistance connected between its R.C. circuit and the voltage source and a capacitor connected between the R.C. circuit side of the further resistance and earth.

A machine control receives programmed information, as from a perforated programmed tape, for controlling a machine, such as a turning machine. The programmed information includes blocks of machine control information with each block including at least one machine control function word, such as an X displacement command word. The programmed blocks of information are read from the programmed tape and recorded on an auxiliary recording medium, such as a magnetic cassette tape. Facilities are provid...

A program control system is disclosed wherein the coordinates of a plurality of specified points of a prescribed path in the space to be traced by a manipulator assembly which are spaced apart from each other by a line segment of the same unit length are stored in a storage device in a teaching mode, and one set of coordinates of the adjacent specified points are simultaneously and sequentially read out from the storage device in a repeat mode so that the position command signals or coordinates ...

Program control device, e.g. for a tube bending machine, the device comprising a program carrier in the form of a flexible cam-carrying band tensioned about the cylindrical periphery of a program disc rotatable by the drive of the machine, a command device mounted on the framework of the machine and including followers engaging respective cams during rotation of the disc and thus controlling the operation of corresponding operative members of the machine. The cams are arranged on the band in ind...

Television programs schedules and visual time information are displayed by projection of composite images from the frames of a film strip and slides respectively displaced in synchronism on a cyclic basis and unidirectionally advanced at the end of each regular program period under control of a timer. During film frame movement, other visual material may be projected from intermediate slides in synchronism with audio message signals.

A program controlled testing system for a device or component comprises a program control unit which supplies an instruction for addressing a device or component to be tested. An output data is obtained from the device, and is compared against a reference data contained in the instruction. The comparison result controls the address to which the program of the program control unit is to be advanced. The address for specifying the device or a particular location thereof to be tested is stored in a...

A program control device controls a plurality of power units of a controlled object having operation member means in accordance with program information which is memorized in a memory device. The program information consists of step information and point information. The point information instructs the command positional values of the operation member means. The step information includes a control command to control functions of the program control device and a memory address command to instruct...

The invention relates to a programmable timing device of the type which controls a utility unit such as a heating plant on a daily and weekly schedule. The timing device includes clock works and a rotatable unit driven by the clock works. A reflecting disc having a reflecting surface is mounted on the rotatable unit for rotation therewith. A stationary unit holds a light source which directs a light beam towards the reflecting disc. A program disc is mounted on the rotatable unit between the ref...

A program timer wherein a single three blade switch assembly is utilized for both the line switching function and a cam track operated switch.
