Abstract: La présente invention concerne un annuleur d'écho pour un terminal d'un système de transmission de données en duplex à modulation de porteuse. Cet annuleur d'écho comporte un filtre transversal numérique complexe, à coefficients asservis et à domaine de temps ayant un écart entre prise égal à un sous multiple 1 de l'intervalle de Baud .DELTA. et recevant en entrée une suite de symboles complexes de débit 1/.DELTA. constitués de symboles complexes délivrés par le codeur de l'émetteur du terminal avec un débit 1/.DELTA. et de 1-1 symboles nuls intercalés entre chacun d'eux. Le filtre transversal est suivi d'un modulateur numérique employant la fréquence de porteuse de l'emetteur avec des valeurs instantanées mises à jour avec une périodicité d'un intervalle de Baud et délivrant la copie d'écho en bande passante. Il est particulièrement intéressant pour les systèmes de transmission dans lesquels le produit de la fréquence porteuse d'émission par l'intervalle de Baud est un multiple entier de un quart car la réalisation du modulateur numérique devient alors très simple

Abstract: ABSTRACT    A cylindrical elastomeric bearing for carrying relatively large compressive radial loads while accommodating thrust and torsional loads acting along the bearing's longitudinal axis.  The bearing generally comprises a rigid interior member and a rigid exterior member, with the two members being joined together by bonded concentric laminae comprising alternating strata of resilient material and non-extensible material.  The fatigue life of the bearing is enhanced by forming each resilient stratum with a shear modulus of elasticity such that the stratum will tend to carry a strain substantially equal to the strain carried by every other resilient stratum when the bearing is sub-jected to a wide range of different torsional loads.  The desired shear moduli of elasticity are attained for the different resilient strata over a wide range of different torsional loads by forming at least some of the resilient strata from two or more substrata of selected thicknesses wherein each substratum within a given resilient stratum com-prises a resilient material having a unique shear modulus.

Abstract: SETTING MECHANISM FOR SNAP ACTION CIRCUIT BREAKER             ABSTRACT OF THE DISCLOSURE    A circuit breaker comprising an electrically insulating housing, an overcurrent sensor in the housing, a stationary and a movable contact in the housing, and a latch mechanism coupled to the movable contact.  The latch mechanism is tripped in response to a sensed overcurrent; an overcenter spring is coupled to the movable contact for opening and closing the contacts with a snap action when the latch mechanism is tripped.  An elongated handle member extends through a handle opening in the housing and is movable axially between a contacts open position and a contacts closed position.  Handle link means couples the handle member to the latch mechanism and translates a longitudinal movement of the handle member into a rotational movement of the handle link to urge the latch mechanism into the contacts closed position.  The handle link means is also operable to retain the handle member in its second position upon manual movement of the handle member from its first to its second position and for permitting tripping of the latch mechanism and opening of the contacts independently of movement of the handle member.  The handle member also has means associated therewith to inhibit rotational move-ment of the handle member while permitting longitudinal movement.

Abstract: ABSTRACT OF THE DISCLOSURE     A canister to be used in the fuel supplying system of an internal combustion engine of a vehicle, is disclosed.  The cansiter is provided with a fuel vapors guiding pipe for guiding the fuel vapors from a fuel vapors inlet port into a bed of adsorbent material accomodated within a housing, and a deflector for deflecting the flow of fuel vapors guided by the guiding pipe so as to be dispersed throughout the bed. The deflector is formed of air-permeable material having a flowing resistance slightly larger than that of the bed into a frusto-conical plate.  According to the present invention, one part of the fuel vapors flowing into the bed through the guiding pipe in the fuel vapors adsorbing process flows along the upper surface of the deflector in the direction of the upper portion of the bed and another part of the fuel vapors flows through the deflector in the direction of the lower portion of the bed.  Fresh air sucked into the bed in the fuel vapors purging process flows through the bed without being obstructed by the deflector so that the fuel vapors adsorbed by the whole bed are purged.

Abstract: ABSTRACT            A method and apparatus are disclosed which provide a common handshaking protocol for the 201, 202 and 208 modems.          This novel handshaking sequence trains up any echo canceller in the circuit, detects the presence of any echo suppressor and uses a conventional signal preamble in the presence of echo cancellers and a sacrificial carrier sequence in the presence of echo suppressors.  As in the prior art, a ringing signal is applied to an answer modem in response to a signal from an ori-ginate modem, the answer modem is connected to the communication line after receipt of the ringing signal, and an answerback tone is transmitted from the answer modem to the originate modem after a period of silence following connection of the answer modem to the line.  After receipt of the answerback tone, the originate modem is connected to the communication line.  In accordance with the invention, this is followed by a period of silence that is sufficiently long to reactivate any  echo suppressors in the communication line.  Thereafter at least two training sequences are transmitted, one from the originate modem to the answer modem and the other from the answer modem to the origi-nate modem, each training sequence being sufficiently long to train up any echo canceller in the line.  The lengths of the training sequences as received are compared with their lengths as transmitted to determine if the length of the sequence was shortened by an echo suppressor.  If the length of the training sequences as received are significantly shorter than their lengths as transmitted, a sacrificial carrier is transmitted at the beginning of each transmission of data in a new direc-tion.  In the event the training sequences as received are not significantly shorter, each transmission of data in a new direc-tion begins without a sacrificial carrier.  As a result, greater data throughput can be achieved in the absence of echo suppres-sors and errors can be avoided while echo cancellers are being trained.

IPC: B41J2/12
Filed: 1982-07-23
Granted: 1986-01-21
Abstract: ABSTRACT   An improved ink jet marking architecture for enhancing ink droplet placing accuracy. The improved architecture combines a bipolar scanning arrangement with a drop interlace scheme. The preferred marking apparatus comprises an array of ink jet column generators which direct ink droplets to first a charging region and then through a deflection region. The droplets are charged either negatively or positively depending an a desired droplet trajec-tory; thus the bipolar designation. The deflection region has an electric field strength slightly less than the breakdown field strength of air for the environment in which the apparatus is to operate. The high field strength reduces the charge which must be applied to the droplets and therefore minimizes the drop to drop coulomb interaction. The interlace strategy causes sequential drops from a given generator to be printed in non-sequential locations on the paper. This strategy spreads out the ink droplets in space and results in a reduction of both aerodynamic and coulombic interaction between droplets. By reducing these interactions and minimizing the time of flight for the drops the placement accuracy is increased.  The placement accuracy is further enhanced by utilizing a charging scheme which takes into account the charge induced on other droplets in close proximity of the droplet to correct for coulomb interactions even the bipolar plus interlace strategy cannot avoid.
