Title: Oscillatory band and hammer dot matrix printer
Inventor: COLE NORMAN F
IPC: B41J2/31
Filed: 1981-06-05
Granted: 1984-04-10
Abstract: OSCILLATORY BAND AND HAMMER DOT    MATRIX PRINTER                             Abstract Described, is a printing mechanism allowing full exploitation of the potential of dot matrix printing. Dot forming elements are mounted on a carrier for transport past an array of hammers located in front of media to be marked upon.  The dots or carrier are im-pacted by the hammers to form dots on the medium.  By appropriate control of motion of the printing medium and timing of the hammer impacts, a dot may be formed anywhere on the surface of the medium.  This allows un-limited character font set generation as well as special character printing for enlarged font, miniaturized font, fast rough draft copy printing, the printing of ascenders and decenders for characters and for condensed or compacted printing.  In addition, the mechanism permits an all points available graphics generation system and full control for variable vertical spacing of printed elements and of variable horizontal spacing of the printed elements.  Variable print element shapes, grey tone graphics printing and multi-color additive or subtractive color processes are also facilitated. To improve the throughput speed, a reversible motor is used for driving the dot element carrier and a plurality of dot font sizes and shapes are provided on the carrier. By selection of the required font size and shape and by comparison with the presently known position of the carrier, the quickest access to the next desired dot font for any given hammer can be achieved.

Abstract: Abstract of the Disclosure This invention relates to a feeder 10 for glass fibers useful in feeding glass fibers to a wet-mat process.  Previous fiber feeders were unreliable and caused process disruptions primarily due to fiber conveying belt breakage.  Belt breakage in the present fiber feeder is substantially eliminated by providing a belt pulley comprising an open-ended cylindrical drum 52 having a plurality of staggered waste fiber intake openings 54 longitudinally and circumferentially distributed over the drum.   The intake openings 54 are staggered and sized to eliminate interference with the motion of slats 60 which comprise the fiber conveying belt 50, to ensure sufficient flow of waste fiber 36' out of the drum 52 and to eliminate any potential accumulation of waste fiber 36' between the belt 50 and the belt pulley 48.

Abstract: L'invention concerne un procédé de conduite d'un réacteur nucléaire par déplacement dans le coeur de ce réacteur de barres de commande. Lorsque le paramètre de conduite (.DELTA.T) est dans sa bande morte, on opère une correction de la déviation axiale de puissance (DA) par déplacement d'au moins un groupe de barres de commande, lorsque DA est à l'extérieur d'un intervalle prédéterminé ou bande morte encadrant une valeur de référence DA réf. Le groupe déplacé est choisi en fonction du signe de .DELTA.T, de la position de .DELTA.T par rapport à sa bande morte et de la position des autres groupes. Lorsque .DELTA.T est à l'extérieur de sa bande morte, on fait varier les écarts entre les amplitudes d'insertion des groupes participant à la conduite du réacteur par arrêt ou démarrage de groupes sélectionnes en fonction de la position des groupes de barres dans le coeur du réacteur et de la position de DA soit par rapport à sa bande morte, si DA est à l'extérieur de cette bande morte, soit par rapport a DA réf, si DA est à l'intérieur de cette bande morte. L'invention s'applique, en particulier, aux réacteurs nucléaires à eau sous pression.

Abstract: MULTIPORT MODEM AND THE USE THEREOF IN A METHOD AND A SYSTEM FOR TESTING  A MULTILEVEL COMMUNICATION NETWORK                    Abstract A method of testing a communication network that comprises first and second multiport modems communicating with each other through a transmission channel.  Each of said modems is provided with a number of input/output interfaces and each of the interfaces on either modem is associated with a corresponding interface on the other modem.  In accordance with the method of the pre-sent invention, a test request is applied to one of the interfaces on the first multiport modem, which responds thereto by generating a test configuration code identify-ing that interface.  This modem is then caused to assume a so-called test configuration, in which only that inter-face to which the test request was applied is active, and a test command comprising an indication of the test to be performed and a link level identifier is applied to that interface.  If the identifier designates the link level to which the first modem belongs, this modem will control the test specified in the test command.  If another link level is designated then the test command and the test configuration code will both be sent to the second multiport modem.  The second modem will then decode the link level identifier and, if the link level so designated is not the one to which is pertains, will assume a test configuration such that only the interface associated with the first modem interface which received the test request will be active, and the test command will be applied to that active interface.  In accordance with another aspect of the invention the test configura-tion code also identifies the bit rate associated with the test command.  The invention also provides a test system that implements the above method.  The invention further provides an improved multiport modem to be used in conjunction with the test method and system men-tioned above.

Abstract: A method and apparatus for operating an electric ignition, internal combustion engine that substantially improves the fuel efficiency by utilizing heat normally discharged to the ambient to condition and prepare the fuel mixture prior to entry into the combustion chambers. The apparatus comprises a fuel vaporizer (50) that transfers heat from the engine coolant system to the fuel mixture as it leaves a fuel introducing device such as a carburetor (33); a fuel mixture heater (52) for heating the mixture above the vaporization temperature of the liquid fuel; and, a mixture homogenizer (54) for thoroughly stirring the fuel mixture that is located in the fuel mixture flow path intermediate the vaporizer and heater. The homogenizer is operative to compress the fuel mixture under certain engine operating conditions and the heater forms the intake manifold for the engine and includes branch flow paths (152a) and associated conduits (164) that communicate directly with each combustion chamber (32) through a valve controlled port (34a). The fuel mixture flow path from the homogenizer is constructed to minimize energy losses to the ambient.

Abstract: BI-DIRECTIONAL CATV DATA TRANSMISSION AND CONTROL SYSTEM           Abstract of the Invention A bi-directional data transmission and control system utilizing a central processing unit and a multiplicity of remote subscribers.  Each subscriber is provided with a terminal coupled with the central processing unit by a suit-able medium such as a CATV channel.  Each terminal is provided with a demarcation plane separating common circuitry from a number of specialty modules and a common bus therebetween for circuitry simplification, application expandability and individual tailoring.  The data transmission scheme efficiently utilizes the frequency spectrum and enhances polling frequency by permitting selective polling of any given specialty module or subscriber at any given time and by permitting simultaneous polling of every subscriber for service calls, thereafter locating the caller with minimal polling.  Data transmission protocol is expandable or contractable for each terminal independently of others and permits data transmission between any two points in the system.  The system is zoned such that failure of one zone does not disable the entire system.

Abstract: ABSTRACT OF THE DISCLOSURE     A non-woven textile fabric having good pliability and durability is produced by calendering a fiber assembly, partially applying a bonding agent to the fiber web, drying the bonding agent, and applying heat and pressure to force the bonding agent into the fiber web and to densify the web in areas where the bonding agent is present.  The heat and pressure step does not effect polymerization and crosslinking hardening of the bonding agent, but does allow the portions of the web having no bonding agent to expand to high bulkiness.  Subsequently the web is subjected a heat treatment step in which crosslinking and polymerization of the bonding agent occurs.
