Patent EP-0074789-A2 (EP)
Inventor: SHAW HERBERT JOHN
IPC: G02B6/28
Filed: 1982-09-08
Abstract: A fiber optic directional coupler (10) comprises a pair of bases (16), with respective longitudinal, arcuate grooves (13) formed therein on confronting faces (14) thereof, for mounting a pair of optical fibers (12) in close proximity. A portion of the cladding is removed from each of the fibers (12) to form planar facing surfaces (18) which permits the spacing between the fiber cores to be within a predetermined critical zone (34) so that guided modes of the fibers (12) interact, through their evanescent fields, to cause light to be transferred by evanescent field coupling between the fibers (12). The coupler (10) is "tuned" to a desired coupling efficiency by offsetting the planar facing surfaces (18) to increase the spacing between the fiber cores. A method of manufacture of the coupler includes procedures which permit the coupler halves to be made symmetrical. The method also permits couplers (10) having given coupling characteristics to be reproduced.

Filed: 1983-10-03
Abstract: To avoid overloading the rotor winding in rotor-critical operation of a squirrel-cage motor by excessively frequent switching on, the overload protection triggered by a voltage corresponding to the square of the rectified stator current is designed such that the voltage is picked off as the voltage drop on a switchable resistor arrangement (RH1, RH2) and the switching device (U) for the resistor arrangement is switched as a function of exceeding a specific multiple of the rated current (JN). The higher resistor (RH2) is dimensioned for starting the machine such that three successive starting procedures can be carried out successively when the machine is cold, and only two starting procedures can be carried out when the machine is warm. <IMAGE>
Patent EP-0091172-A2 (EP)
Inventor: THORDARSON GUNNAR GUDMUND
IPC: F42C13/04
Filed: 1983-04-05
Abstract: The invention relates to an electromagnetic proximity fuse operating with transmission of an electromagnetic HF-wave and reception of a reflected wave received after reflection against an object, which reflected wave is combined with the transmitted one for generating a signal of doppler frequency (f a ) or so called doppler signal, which is used to initiate an ignition circuit. According to the invention the said doppler signal is led to an analogue divider (12) together with a delayed version of the said doppler signal. The analogue divider (12) delivers an output signal of doppler frequency (f d ), the amplitude of which is equal to the quotient between the prevailing value (U 1 ) of the doppler signal and the value of the doppler signal a predetermined time interval previously (U 2 ). This quotient signal of dopper frequency is led to a filter (15), which at least approximately has a frequency characteristic equal to 1/(f o  + f), where f o  is a system parameter and f is the input frequency, i.e. in the present case equal to the doppler frequency (f d ). The output signal from the filter (15) is finally led to an ignition circuit (17) via a threshold circuit (6) having a fixed threshold in order to initiate the ignition circuit (17), when the output signal from the filter exceeds a given value. Hereby the ignition circuit (17) will be triggered at a constant distance from the reflecting object independently of such unknown variables as the approaching speed, the reflection factor of the object and the gain factor of the HF-system.

Abstract: A seat is mounted on right and left slide rails (23,24) slidable on right and left guide rails (21,22) so that the position of the seat is adjustable back and forth. Right and left lock mechanisms (25,45) are mounted on the right and left slide rails, respectively, for locking a relative movement between a right or left pair of the slide and guide rails. A handle bar (26) is connected with the left lock mechanism (25), for example, and extends forwardly so that the left lock mechanism is unlocked with the handle bar. The motion of the handle bar for unlocking the left lock mechanism is transmitted through a release wire (44) and link mechanism (39,42) to the right lock mechanism (45) to unlock the right lock mechanism together. The release wire extends from the handle bar adjacent the left slide rail to the right slide rail near the front of the seat. The link means extends backwardly along the right slide rail from the end of the release wire to the right lock mechanism. The link means makes it possible to displace the position of the right end of the release wire toward the front of the seat.
