Abstract: METHOD AND APPARATUS FOR SIGNALING IN A COMMUNICATION SYSTEM ABSTRACT OF THE DISCLOSURE A method and apparatus are disclosed for using a specified pattern of signal events for signaling in a digital communication system. Illustratively, detection of a first event in a control signal activates timing apparatus which looks for a second event in a control signal within a specified time "window" and at least one additional event in either a data or a control signal within a specified time period. Preferably, the first event is a drop in one of the carrier detect or request to send signals and the second event is a rise in the same signal. The additional event illustra-tively is reception of two identical data characters, each representing an address and an operation code. Each of these two characters must be received and compared for verification within the specified time period in order to produce an output control signal decoded from the operation code. This signal may be used for any application such as the activation of a terminal to receive data, the initiation of a test sequence, or a change of the network configuration.

Abstract: Abstract of the Disclosure A readily adjustable machine which continuously produces corrugated flexible metal tubing from very light gauge metal and of various diameters.  A warping ring receives there-within a longitudinally corrugated narrow strip of formable metal of light gauge and warps the same helically to produce convolutions by means of a helical warping surface which extends into one of the longitudinal corrugations.  The size of the tube produced can be varied by merely substituting a warping ring of a different size.  A uniquely shaped pair of die-forming rollers have lock-seam forming surfaces which are adjustable relative to each other to provide variation in the degree to which the seam will permit and withstand axial torque.  The lock seam is constructed to be symmetrical about the neutral axis of the corrugation and about the slope line of the common corrugation leg of adjacent convolutions which it constitutes.  The lock is provided by its radially extending deformations in its longitudinal medial portions and terminal portions, with intermediate portions therebetween extending at about 60 degrees thereto.  The terminal portions extend around the bottoms of each of the U-shaped seam elements to further lock them in place.  A flying saw automatically cuts off predetermined lengths of the tubing.  The length of the sections to be cut may be varied by merely re-positioning a movable switch in the path of the tube.  The tube has a unique lock-seam which is constructed to withstand greater flexing, greater axial twist and more stress without damage and without opening, and is stronger.

Abstract: ABSTRACT           The invention relates to a method of controlling the execution of suspended processes in a data processing system.          Each process to be suspended includes a command defining the time period of the suspension required for that process.  The interval can take any value in predetermined steps up to a fixed maximum and no limit is placed upon the number of processes which can be simultaneously suspended.  Each process has a segment of storage used when the process is suspended and all processes which are suspended for the same time period, but at different real-time starting points, are chained together in the order in which they are suspended using pointers in their segments and timing chain header segments.  The chaining is achieved using forward and back-ward pointers forming the segments into a circular list.  The timing chain header segments are also linked into a separate second list, and each timing chain segment includes a time value indication of the real-time at which the earliest suspended process is to be re-run,  The system also includes a timing chain monitor-ing process (called an usherette process) which scans the timing chain headers to ascertain suspended processes which are to be removed from the suspended lists and, after reforming any modified timing chain list, the process computes the time that it should next run based upon the time value indications in the timing chain header segments.

Abstract: MICROCONTROLLER FOR DISK FILES                Abstract A microcontroller for controlling the bidirectional transfer of data between a control unit and a plurality of disk drives is disclosed.  The microcontroller has a fixed machine cycle time for executing each instruction and is arranged to fetch the next instruction during the execution of the current instruction.       The microinstructions are stored in an addressable memory and each addressed instruction is transferred to a control subsystem in response to the operation of a second subsystem whose function is to generate the address of the next instruction to be executed. A third subsystem is provided for executing the instructions which is also employed during branch type of instructions for assisting the second subsystem in generating the next address.       The second subsystem also functions to supply the third subsystem during execution of certain instructions, data to be stored for use during subsequent instructions.       The subsystem for executing instructions is characterized by a plurality of data sources which are selectively interconnected through the ALU to the ALU register during the input phase of a machine cycle and a plurality of data destinations which are selectively connected to the output of the ALU register during the output phase of a machine cycle.  One of these destinations is the subsystem for fetching the next instruction.      The subsystem for fetching the next instruction is characterized by a plurality of partial address generators which operate selectively with the other subsystem to generate the complete address of the next instruction.      The controller also employs a multilevel priority trap system for interrupting the normal sequencing of instructions in response to events occurring in the devices being controlled or events within the microprocessor.
