A video program distribution system is described in which the video programs in the form of video signal modulation on carrier waves is applied to a common video transmission line and, by that line, to a remote switching station, or street unit, associated with each of the system's customers. each customer has a video transmission extension line which interconnects his television receiver or monitor with the remote switching station. The remote switching station includes switches which can be ac...

To provide for uniform timing of program control cycles in which different control cycles have different cycling time, the control cycles being connected in parallel to a program control arrangement, timing elements are connected in the respective signal paths controlling the respective cycles and adding time increments to the signals coursing in the respective paths between the input and the output to at least approximate the coursing time of all signal paths to a uniform time duration; if the ...

A method for use in an electronic digital signal processing system for improving execution time in locating requested programs, reducing program storage requirements in memory and improving packaging and repackaging of programs on direct access memory devices for the library. A program data set for a system is formed to recognize the references to character program names and to resolve those references into control section identification codes. Each referenced character program name is uniquely ...

A sequence program inputting device in a programmable sequence controller includes a separate producing circuit for producing a ladder diagram to be displayed on a display screen and a separate converting circuit for converting the ladder diagram to a machine instruction sequence of the programmable sequence controller to enable independent operations of those circuits.

An audio program signal is converted into 12-bit PCM words and two 12-bit words are inserted into three 8-bit time slots in a T1 line. To avoid interference from a "yellow" alarm in which the second bit positions of all of the 8-bit time slots are pre-empted, the three least significant bits are placed in the second, sixth and tenth bit positions of the 12-bit words, which alone can occupy the second bit position of the 8-bit time slots. A translator for generating the 12-bit words from 14-bit l...

A flexible arm for a program controlled manipulator, with a hydraulic rotary actuator supported on an inflexible arm, a first arm member secured to a rotary shaft of the actuator, a second arm member connected swingably to the first arm member by way of a shaft, a third arm member connected rotatably to the second arm member, a link member connected rotatably to the first and third arm member, and a working tool mounted to the free end of the flexible arm.

A program debugging system for a computer having an arithmetic/logic controller for implementing operations for data in accordance with a stored program and a program debugging device for issuing commands for correcting program errors to the arithmetic/logic controller, the system comprising a readout data addressing unit incorporated in the program debugging device for specifying the address of data which has caused an error in the arthmetic/logic controller, an address setting memory for writi...

In the field of automatic boiling in a pan in which the consistency of massecuite is controlled in accordance with method steps, intermittent boiling is used as an effective way to improve the boiling time and quality of products with supplying of appropriate amounts of water or solution into the pan to control the consistency each time it has reached a set value. This invention provides a novel method for controlling the consistency of the massecuite, wherein two curves are established defining...

A method for automatically generating by use of a computer a simulation program for simulating a phenomenon in a region by discretizing automatically data of a partial differential equation inputted when the partial differential equation and boundary conditions governing the phenomenon and data representing the shape of a region, which is an object of calculation, are given, by using a discretization rule by the finite differential method, and for generating a program calculating numerical value...

A process which allows the entering or retrieval of data without the concern of the units attached to the data. This is achieved by converting the input data into an internal data format, the internal data format having a numeric value and units which are equivalent to the input data. To retrieve data, the user selects the desired units, and the system converts the internal data to the desired units, and then outputs the result.
