Abstract: Abstract of the Disclosure A network control and test system for application to data communications networks.  In a first mode of operation, the system learns the network configuration automatically and builds a table describing the network configuration.  In a second mode of operation, the system automatically monitors the status of the network and each of its component units, periodically polling the network for changes of status and updating the information in the network configuration table to reflect such changes.  In a third mode of operation, selective sites in the network may be tested under control of the system at previously selected and entered times of day, at which times previously chosen tests are performed without the need for operator intervention.  In a fourth mode, an operator can manually command the system to perform certain tests and control functions.  A central site in the network includes the primary components of the system and each remote site includes a remote test module which operates under the control of and in cooperation with the central site equipment.  The central site equipment includes a three-tiered, partially distributed data processing system having a semi-autonomous data processing system at each tier.  Each of the tiers has predetermined functions and responsibilities.  Extremely flexible and powerful operation is provided by this architecture.

Abstract: Abstract In a pump having a cylinder liner, there is a piston therein, a seal around the piston and rear wearband around the piston body to align the piston within the liner.  An elastomeric seal ring is in sealing and sliding contact with the liner.  A gap filler, with minimal axial creep and controlled radial creep, abuts the rear surface of the seal and maintains continuous contact with the liner whereby continu-ously closing the extrusion gap between the gap filler and the liner as the liner wears.  The wearband has a plurality of angled grooves longi-tudinally traversing it.  Abrasive particles are directed within and through the grooves in the wearband while a source of liquid is communi-cated into the piston body, through water channels in the gap filler and through the flowpaths in the wearband to create a vortex action which washes the liner wall.  The wearband insures no metal to metal contact between the piston and liner and provides a constant piston gap between the metal piston and liner.  A thin seal ring improves the temperature gradient within the ring, controls the creep of the ring, reduce the axial load on the sing and allows rear removal of the ring without removing the piston from the liner.

Abstract: RECORDING MEMBER          Abstract of the Disclosure The invention relates to a recording member having a predetermined substrate, and a thin film which is formed on the substrate in which recesses or pits can be formed for recording information when irradiated with a working beam, e.g. a laser beam.  The thin film is formed of an inorganic material which contains at least arsenic, selenium and tellu-rium.  The distribution of either of the Se and the Te decrea-ses from a part near the surface of the thin film towards a central part thereof, while the distribution of the As increa-ses from a part near the surface towards the central part.          This recording member can provide a high signal-to-noise ratio and a long lifetime because the oxidation of arsenic limited and therefore the structure remains stable even over long periods of time.

Abstract: ABSTRACT OF THE DISCLOSURE                 A method of measuring the rigidity, the damping coefficient and the inertia of a system consisting of a damped, spring-supported mass, particularly, the manually operable member of the control-system of an aircraft or a flight simulator, in which method the measurement of the rigidity takes place by determining the relationship between the force exerted on the mass and the deviation of the mass from the state of equilibrium at a speed and an acceleration of substantially zero value and storing the relationship.          The method is characterized by the initial step of forming three electric signals--namely, a force signal having a value directly proportional to the force exerted on the mass, an acceleration signal having a value directly proportional to the acceleration of the mass, and a velocity signal having a value directly proportional to the speed of the mass.  There-after, the mass is moved in a manner such that it attains an acceleration and a velocity having values differing from substantially zero and the amplitude of the acceleration signal and of the velocity signal is adjusted such that by subtracting these two signals from the force signal substan-tially the same relationship to the deflection is obtained as in measuring the rigidity.  A device for carrying out the method is also provided.

Abstract: ABSTRACT OF THE DISCLOSURE     An active filter separates the function of a principal feedback loop which provides velocity error correction from that of a nested feedback loop which provides video signal frequency correction.  A further feedback loop responsive to the active filter output signal normally open under steady-state conditions, is closed under transient conditions for supplying a limited gain reducing signal to the input of the active filter whereby transient disturbance of the primary and nested loops is minimized with no loss of loop gain under steady-state conditions.  The third loop includes a dead zone amplifier for distinguishing between transient and steady-state conditions and a limiter for limiting the gain reducing signal to level below that which otherwise would tend to drive the active filter to a non-linear slow recovery condition.

Abstract: Disclosed is a process for the transmission of information over television networks wherein certain information is encoded in digital form and transmitted by supplementing and/or replacing the information forming the conventional program. The digital information is received by a conventional receiving set equipped with a decoding, memory and detector means. Information is transmitted in the form of analog signals subdivided into scans or groups of scans, each scan having associated identifying material. The information transmitted in digital form has other identifying material and is transmitted generally synchronously with the corresponding information in analog form. The transmissions are received by receivers with detectors sensitive to the identifying material and which have analog-digital and inverse conversion means as well as memory and decoding means to reproduce the information contained in the analog and digital signals.

Abstract: The present invention relates to a method of three-dimensional visualization of an object and a device therefor. A video camera, equipped with an image numerator takes photographs supplied by an electron microscope, for different angular positions of an object. The images which are numbered thus are applied to a digital image memory. Under the control of a visualization clock, this memory delivers the line of the same range taken successively in each of the base images to an image visualization member. The member reproduces its lines consecutively, and thus forms a composite image which may be used for relief visualization. In order to re-establish the format of the image, an anamorphosis is carried out, for example, by repeating n times on each line of the composite image each of the image points selected in one of the base images. The composite image which is obtained thus is provided with a lenticular grating of sectors of a cylinder.
