Title: Electromagnet system and process and device for joining the core and yoke in an electromagnet system
Inventor: HENDEL HORST
IPC: H01H49/00
Filed: 1992-06-22
Abstract: Abstract The electromagnet system has a bent yoke (3) and a round core (4) which has a constant cross-section from its pole end (4a)  but,  towards its mounting end  (4b),  has an outwardly expanded tapered section (4c). The core (4) is inserted from the outside into a hole (3c) in the yoke, with its pole end (4a) in front, and is adjusted and fixed by means of pulse-like shocks.            In consequence, a uniformly reliable firm seat can be achieved using relatively  small  joining  forces.  The knocking in of the core using force pulses requires no opposing support of the relay construction, since the opposing force is produced mainly by the inertia of the yoke and of the coil system.

Title: Filter
Inventor: JANTUNEN HELI
IPC: H01P1/20
Filed: 1994-02-24
Abstract: Abstract A  transmission  line  filter  comprises  four  resonators (100,200,300,400),and transmission zeroes can be added to the transfer function of the filter using a known phasing coupling technique using a transmission line (53,54) coupled between two resonators. The location of the transmission zeroes can be varied using control circuits  (A,B). Each control  circuit  comprises  a  series  coupled  inductance (55,58)  and  capacitance  (56,59)   forming  a  resonance circuit,the resonance frequency of which can be varied using a variable d.c. voltage (V1 ,V2 ). The inductance of each control  circuit  is  arranged    adjacent  its  respective transmission   line   so   that   the   two   are   weakly electromagnetically  coupled.  By  supplying  the  variable voltage to the resonance circuits,normal operation of the phasing coupling is affected, thereby varying the location of the transmission zero.One or more control circuits can be provided for filters having transmission zeroes in their transfer function which need to be varied the provision of these  control  circuits  allow transmission  zeroes  to be selected in situ,rather than solely during manufacture.

Title: Compensation device
Inventor: SIERENS CHRISTIAAN H J
IPC: H04B10/2513
Filed: 1994-04-26
Abstract: ABSTRACT - COMPENSATION DEVICE         The compensation device is used in an optical network where signals are transmitted from a main station (M) to one or a plurality of user stations (US1 to US3). It compensates for analogue optical signal distortion caused by laser chirp of a laser in the main station (M) which generates said analogue optical signal and fiber dispersion of the fiber link over which the optical signal is transmitted.          The device includes a distance measuring device (R) generating a result signal (MS) indicative of the distance between the main station and the user stations and which is possibly already available in the network to perform ranging when the latter network is also used to transmit digital signals from the user stations to the main station using Time Division Multiple Access.  It also includes a processing circuit (PC) which in response to a given laser chirp and the result signal, provides a tuning signal (V) to tune the bias voltage of a varactor diode (VD) which is part of the compensation circuit inserted in the electrical signal path.          In an optimal implementation the measuring device (R) and the processing circuit (PC) are located in the main station (M), whilst the varactor diode (VD) is located in each user station.

Title: Multicolour voltage tunable quantum well intersubband infrared photodetector and associated method
Inventor: LIU HUI C
IPC: H01L31/0352
Filed: 1994-07-07
Abstract: A quantum well intersubband infrared (IR) photodetector has a spectral response tunable by an external voltage. The photodetector consists of multiple doped quantum wells with different well widths and barrier heights. The preferred embodiment is made by repeating the whole structure of the active region of a multiple quantum well intersubband IR photodetector. Differences between repeats or groups of well widths and barrier heights result in differences in the spectral IR response of the different repeats. The device resistance of a given group is designed to be very different from those for all the other groups. As a function of an applied voltage, the repeat with the highest resistance will be turned on to detect IR with the response peak at a wavelength .lambda.1. Subsequently, the next highest resistance repeat will turn on when increasing voltage with its response peaked at .lambda.2, and so on. Since .lambda.1, .lambda.2 are different from each other, a voltage tunable multicolour photodetector is realized.

Patent CA-2139813-A1 (CA)
Title: Transmission process and multiplex optical link with amplification
Inventor: BAYART DOMINIQUE
IPC: H01S3/094
Filed: 1995-01-09
Abstract: The method includes dividing amplifier gain between several multiplexed carrier waves. The desired division is maintained when the number and/or power of the carrier waves move away from predetermined values. The power of the amplified light is independent of the carrier waves and the gain division gives the same amplification to all the carrier waves.  An amplified laser light is passed to a coupler (16) which detects the power from a fibre optic amplifier (10). The signal is optically filtered (24) and passed to a photodiode (18). A voltage level output from the photodiode is input to an amplifier (20) and regulator (22). Signals from the regulator pass to two laser pumps (12,14). Varying the voltage input to the laser pumps adjusts gain to the overall level required for the channels used.
