Abstract: Polarization-independent optoelectrical change-over switch on a wafer of double-refracting crystal material with an optical axis Z. The change-over switch has a region of interaction L1 with optical waveguides 103, 104 and an electrode arrangement. The region of interaction L1 is divided into two sections S3, S4 with two inner electrodes 106, 107; 110, 111 and two outer electrodes 105, 108; 109, 112 in each section. Connected to the electrodes are voltage sources 114, 115, 116, 117; 118, 119, 120, 121 which generate electric fields through the optical waveguides 103, 104. The electric field between each of the outer electrodes 105, 108; 109, 112 and adjacent inner electrodes 106, 107; 110, 111 has in each section S3, S4 the same direction in both the optical waveguides and brings about δχ modulation. The electric field between the central electrodes 106, 107; 110, 111 has in each section S3, S4 mutually opposite directions in the two light waveguides and brings about a δβ modulation. In this way, both the cross- coupling state and the through-coupling state can be achieved for both the TE and the TM modes of an arbitrarily polarized lightwave P. The change-over switch can be operated with low voltages and the necessary manufacturing precision is relatively low. <IMAGE>

Abstract: The contactor has a body of electrically conductive material, and has a primary part (11) with a large dia., and a sec. part (12) with a smaller dia. and transversed by a channel (13). The channel issues into a recess (17) with a larger dia. than itself. A fibre component (14) is assembled in the channel at the end of the contactor which is to be coupled to a corresp. female contact unit. The fibre component is squarely cut at both ends to minimise losses when light passes in and out of it. Its outer end surface (15) is arranged at the same height as the mouth of the channel. - The inner end surface (16) of the fibre component is arranged inside the channel approximately in the centre of the body sec. part. The fibre component is firmly anchored in the body with the aid of e.g. epoxy adhesive.

Abstract: The present invention relates to a method and a device for distribution of cooling air to switchgear cubicles. The invention comprises distributing cooling air or other cooled gas, in a series of closely arranged switchgear cubicles (1a-1d) which are closed to the surrounding air, in the cubicles along the same path as that along which the current is distributed through and into the cubicles. This is accomplished by distributing air or gas to the respective cubicles (1a-1d) in the series of cubicles via channels (5, 6a-6d) in the form of protective channels or busbar boxes which constitute semiprotection for the single-phase or multi-phase busbar lanes (4a-4d) which distribute electric current to the cubicles and to electric equipment present in the cubicles. The direction of the cooling gas distribution is the same as the current direction or the reversed.

Abstract: The present invention relates to a method and to an arrangement for automatically connecting a mobile station (A1) in a radio network (RN11) desiring to setup a connection with a subscriber (B1) with an available RAP station (RAP1) which provides the best connection of the RAP stations (RAP1, RAP2, RAP3, RAP4, RAPS) that surround the mobile station (A1). The mobile station (A1) sends a call setup message (CSM) which is received by the surrounding available RAP stations (RAP1, RAP2, RAP3, RAP4). The RAP stations calculate the quality of the received call setup message (CSM) and obtain a signal delay ( DELTA T) on the basis of the calculated message quality value. The RAP stations wait until the signal delay ( DELTA T) expires before sending a response signal or call acknowledge message (CAM) to the mobile station (A1). The mobile station (A1) receives the first obtained response signal (CAM) and in response thereto switches to a call direction change mode (CDC) which prevents the mobile station (A1) from receiving more signals. The mobile station (A1) then sends a select message (SELM) to the RAP station from which it received the first response signal (CAM). The selected RAP station continues with setting up the subscriber connection. <IMAGE>
