Title: Procede et appareil permettant l'application de restrictions sur des appels longue distance emis a partir d'un dispositif de communication sans fil
Inventor: PEARCE GRAHAM N
IPC: H04W4/02
Filed: 2003-02-07
Abstract: Procédés et appareils permettant l'application de restrictions sur des appels longue distance émis à partir de dispositifs de communication sans fil et fonctionnant dans un réseau de communication sans fil. Les appareils sans fil sont de préférence des dispositifs de communication combinés voix et données. Dans un exemple illustratif, chaque dispositif sans fil reçoit et met en mémoire des informations de restriction sur des appels longue distance qui sont introduites à partir d'un réseau informatique privé via le réseau sans fil. Lors d'un fonctionnement typique, un dispositif sans fil détermine si des essais d'appel à partir du dispositif sans fil sont soumis à restriction selon les informations de restriction sur les appels longue distance. Si un essai d'appel est soumis à restriction selon les informations de restriction sur les appels longue distance, le dispositif sans fil applique la restriction à l'essai d'appel à partir dudit dispositif sans fil et fournit un avertissement de restriction d'appel (par ex. avertissement sonore ou texte visuel). Si un essai d'appel n'est pas soumis à restriction selon les informations de restriction sur appels longue distance, le dispositif sans fil permet l'essai d'appel à partir dudit dispositif sans fil. Avantageusement, le contrôle sur les appels longue distance peut être établi sur la base des utilisateurs individuels dans le réseau informatique privé domestique.

Title: High shear jet absorber and gas absorption process
Inventor: CHORNET ESTEBAN
IPC: B01J10/00
Filed: 1989-12-20
Abstract: ABSTRACT     The invention is concerned with a process and an  apparatus  for  absorbing  a  gaseous  substance  by transferring  mass  therefrom  into  a  liquid  solvent capable  of  dissolving  this  gaseous  substance.  The solvent is pumped and the gaseous substance compressed, and  the  so  pumped  solvent  and  compressed  gaseous substance   are   mixed   together   to   produce   a gaseous/liquid mixture. A nozzle produces a jet of this gaseous/liquid  mixture  into  a  hollow  vessel,  which nozzle is structured to impart to the gaseous/liquid mixture a high shear causing (a) a high turbulence in the jet of gaseous/liquid mixture, and (b) spraying of the liquid solvent into fine droplets whereby a high interfacial area between the gaseous substance and the liquid solvent is obtained.  The  high  turbulence  and interfacial  area increase the rate  of  mass  transfer from the gaseous substance into the liquid solvent.

Abstract: Control apparatus for an aircraft area navigation system provides transitioning from an inbound leg to an outbound leg of a lateral navigation waypoint with a fixed curved transition path with or along the outer limit of the protected airspace width or PAW. The present invention determines in conjunction with the aircraft altitude and the angle of the course change a maximum distance that the aircraft will deviate from either the inbound or outbound leg. This distance is sometimes called the maximum cross track error or MXTK. The maximum cross track error information in conjunction with the course change angle is used to generate a turn radius for a fixed curved transition path to be followed by the aircraft independent of ground speed. The turn radius information together with the aircraft ground speed information is used to generate a bank angle bias command signal. The bank angle bias command is calculated to vary the bank angle of the aircraft so as to keep the aircraft on the fixed curved path throughout the transition from outbound to inbound waypoint legs.

Title: Process for preparing 1,1,1,2-tetrafluoroethane
Inventor: CUZZATO PAOLO
IPC: B01J23/26
Filed: 1990-07-10
Abstract: 1,1,1,2-tetrafluoroethane (134a) is prepared by reacting, in the gas phase, trichloroethylene with 1,1,1-trifluorochloroethane (133a) and hydrofluoric acid with trichloroethylene/133a molar ratios ranging from 5/95 to 50/50, in the presence of a catalyst consisting of Cr2O3 carried on AlF3.      The process provides 134a yields higher than 90% and permits an exceptionally long life of the catalyst. In this way it is possible to realize a continuous process by recycling the unreacted trichloroethylene and 133a, thereby making up for the relatively low global conversion of the reagents.

Title: Procedure and apparatus for the combustion and afterburning of residues
Inventor: KUGLER KURT
IPC: F23G5/32
Filed: 1990-01-03
Abstract: Process and apparatus for the combustion and afterburning of residues ABSTRACT          Summary This invention relates to an innovative process and apparatus for the joint combustion of special wastes and for the melting (vitrification) of fine dusts.  This is achieved by separating the burning of slag and the burning of waste gases from one another in terms of the process, in that the temperature of the rotary tubular kiln is controlled by means of a combustion air control system as a function of the slag melt, if necessary with substoichiometric combustion, and the burning of the waste gas takes place with the addition of activated combustion air or oxygen in high turbulence zones of downstream aggregates.            Vitrification agents can be added to the rotary tubular kiln. The fine dusts are integrated with substances; which can be used as energy sources and at the discharge of the rotary tubular kiln are added directly into the slag melt, so that there is a sudden melting and integration into the furnace slag guaranteed by the mixing induced by the rotation of the kiln.            It is also essential that on account of the substoichiometric operation, the requirement for fluid wastes and/or supplemental fuel is drastically reduced, the capacity of the rotary tubular kiln is increased and NOx formation is reduced.

Title: Sliding mode control method
Inventor: TORII NOBUTOSHI
IPC: G05B13/02
Filed: 1990-02-23
Abstract: A B S T R A C T    A sliding mode control method capable of realizing a control system improved in robustness and excellent in control stability.     On the basis of a command position (.theta.r), actual position (.theta.) and actual speed (?), a position deviation (x1), its derivative (x2), an integrated value (x3) of the derivative and an integrated value (x4) of the position deviation are calculated by a processor of a digital servo circuit of a servo control system which has a position loop for proportional control, a velocity loop for proportional-plus-integral control to calculate a torque command and a current loop responsive to the torque command (100 to 103).  A switching plane (s = x2+C?x1+K?x3+K?Kp?x4) and a discrimination reference value (Kp?x1+x2) for the sliding mode control are calculated, and switching amounts (?', ?") permitting the characteristics of the control system to be converged to the switching plane are calculated according to whether the switching plane, position deviation and reference value are positive or negative.  A motor is driven in accordance with a torque command (?=?'+?") obtained by adding the switching amounts together.  The control system, controlled in the sliding mode and having improved robustness, has its characteristics free from variations even when the motor inertia is varied.

Abstract: Method in improving of the precision of impe-dance detectors in radiosondes. In the method, the temperature of the detector or detectors (30 and/or 10) is measured by means of a thermo-couple (20), in which the joint (23) of one branch of its thermoelements (21,22) is placed in con-nection with, or at the proximity of, the de-tector to be measured. In the thermocouple (20) the joint (24) of the other branch is placed in the atmosphere (SA) surrounding the detector. By means of the thermocouple (20), the difference (T1-T0) between the temperature (T1) prevailing in connection with the detector and the tem-perature (T0) in the surrounding atmosphere (SA) is detected. The output signal (fout) of the meas-urement coupling of the radiosonde is affected by means of an electric signal (U(t)) representing the difference (T1-T0) in temperature, which out-put signal contains the data concerning the me-teorological quantity or quantities measured by means of the detector (30) or detectors (10,30). The DC voltage (Uo) obtained from the thermo-couple (20) is converted by means of an inverter (60) or equivalent into an AC voltage (U(t)), by means of which the output signal (fout) of the measurement coupling is affected.
