Patent EP-0113453-A1 (EP)
Inventor: COPPA GIANNI
IPC: G01M11/02
Filed: 1983-12-12
Abstract: The method takes advantage on the fact that in optical-fibre transmission only the fundamental mode is linearly polarized. Linearly-polarized light of different wavelengths is launched into the fibre, is collected by a photodetector (7) after passage through an analyser (6), and then the power of the signal outgoing from the photodetector (7) is measured. 
     The cutoff wavelength is detected in that the signal outgoing from the detector becomes zero.

Abstract: For providing high-quality reproduction of audio in a video tape recorder (VTR), video and audio signals are recorded as first and second mixed signals (M i , M 2 ) in successive alternately arranged adjacent first and second parallel record tracks, respectively, extending obliquely on a magnetic record tape, the first and second mixed signals comprising respective carriers of different frequencies which are modulated by an audio signal to constitute respective FM audio signals (LF,, LF 2 , RF 3 , RF 4 ) mixed with a video signal. In a normal reproducing mode of the VTR, in which the tape is advanced at a normal speed corresponding to that used for recording, magnetic heads (42', 43') scan substantially along the adjacent first and second tracks in succession for alternately reproducing the first and second mixed signals (M 1  M 2 ) therefrom, the FM audio signals (LF,, LF 2 , RF 3 , RF 4 ) are separated from the reproduced mixed signals and are then demodulated for obtaining therefrom respective alternating reproduced portions (SL 1 , SL 2 , SR 1 , SR 2 ) of the audio signal, and the alternately reproduced portions are sequentially combined to form a reconstituted audio signal (SL', SR') therefrom. In another reproducing mode in which the tape is advanced at other than its normal speed, the heads (42', 43') scan imperfectly along the record tracks so that the mixed signals (M 1 , M 2 ) are reproduced therefrom with noise, particularly when the heads are situated adjacent end portions of the tracks being imperfectly scanned, and a noise compensating circuit (97, 98) is operative, in that other reproducing mode, for removing noise from the reconstituted audio signal (SL', SR'), for example by muting the reconstituted signal during the occurrence of noise or by replacing the noise with a predetermined signal level or with the level of a previously occurring signal which has been held.

Title: A control system for an electrically driven vehicle
Inventor: BUKATAREVIC DRAGAN
IPC: B60L50/30
Filed: 1983-07-28
Abstract: A control system for electrically driven vehicles in which energy generated both by the vehicle's (internal combustion) engine and electro-magnetically during braking is achieved by means of a first motor/generator (1) which converts the mechanical energy from the engine into electrical energy driving a second motor/generator (2) which acts as a traction motor, during the acceleration of the vehicle. During deceleration or braking of the vehicle, the second motor/generator (2) behaves as a generator converting the kinetic energy of the vehicle into electrical energy which in turn drives the first motor/generator (1) to rotate a flywheel accumulator (18). During subsequent acceleration, energy generated by the first motor/generator (1) as a result of the flywheel's rotation is used to drive the second motor/generator (2) in traction motor mode. 
     The system also includes a receiver (19) for receiving and processing traffic signal and related information which is applied to control or limitthe operator-control of the vehicle in accordance with that information and a transmitter (20) for retransmitting relevant received information to other road traffic as well as information regarding the speed of the controlled vehicle's movement so as to maintain a constant link between, for example, successive cars in a stream of traffic.

Abstract: @ The leak detector comprises an annular chamber (11) which leads to a circumferential orifice (14) which in turn leads to an annular duct (21) which is symmetrical about the axis of the detector. Barrier gas is fed to the annular chamber (11), for example from an annular chamber (18) and emerges from the opening (20) to form a substantially laminar flow. Leaks are detected by means of a signal gas within an enclosure at a pressure slightly in excess of ambient, and the signal gas is detected from leaks via a probe (2) which is connected for example to a mass spectrometer. The curtain (1) is stable and enables uneven surfaces to be tracked.

Abstract: Le moteur comporte une bobine (16), un stator (11), muni d'un évidement central (13) dans lequel est monté à rotation autour d'un axe (Z) un rotor (18) comprenant un aimant permanent aimanté suivant un axe d'aimantation (A), et des moyens de positionnement (20a, 20b) pour assurer au rotor (18) deux positions de repos dans lesquelles son axe d'aimantation (A) est dirigé suivant un axe d'équilibre statique (YY'). Le stator (11) est formé de deux parties polaires (11a, 11b) qui entourent partiellement le rotor (18) et sont reliées entre elles par deux parties intermédiaires (21a, 21b) et par quatre isthmes (12a-12d) de façon que les parties intermédiaires (21a, 21b) soient coupées par l'axe d'équilibre statique (YY') et que deux isthmes opposés (12a, 12b resp. 12b, 12d) par rapport à l'axe de rotation (Z) du rotor (18) se situent dans une direction (VV', respectivement WW') faisant avec l'axe d'équilibre statique (YY') un angle (α, respectivement β) compris entre 30° et 60°. Deux de ces ishtmes (12a, 12c) qui sont situés dans la même direction (VV') ont une largeur (1) telle qu'ils soient très rapidement saturés en flux magnétique lorsque la bobine (16) crée dans le stator (11) en réponse à une impulsion motrice, un champ magnétique permettant de faire tourner le rotor (18) dans un sens (D), tandis que les deux autres isthmes (12b, 12d) ont une largeur (l') deux à quatre fois supérieure afin que, lorsque la bobine (16) engendre un champ magnétique qui amène le rotor (18) à tourner dans l'autre sens, les isthmes larges (12b, 12d) ou, ici encore les isthmes étroits (12a, 12c) se saturent, mais moins rapidement, afin d'obtenir une différence de forme du courant dans la bobine qui permet à un dispositif de commande associé au moteur de déterminer le sens dans lequel le rotor (18) s'apprête à tourner en réponse à une impulsion motrice et d'éviter toute inversion involontaire des sens de rotation du moteur.
