Title: Optical filter
Inventor: SCHMUCK HARALD DIPL PHYS
IPC: G02B6/34
Filed: 1993-08-21
Abstract: In an optical filter, which is mechanically of simple design and can be produced cost-effectively, with variable wavelength selection, two fibre connectors (2) in each case containing a monomode fibre (3) are each fixed with part of their length in a central sleeve (4) and pushed from diametrical sides over a resonator rod (5). The ends of the resonator rod (5), which contains an optical internal guide (monomode fibre 6), are metal-coated (7). The length of the rod determines the transmission range of the wavelengths. By inserting a resonator rod (5), with a predetermined characteristic, into the centering sleeves (4) of the two fibre connectors (2) or by replacing the resonator rod (5) with another one, different optical filters (1) can be produced or changed over, as required, to another frequency range without any adjustment. <IMAGE>

Title: Electric switch for vehicles
Inventor: BARTHEL KLAUS
IPC: H01H23/00
Filed: 1994-06-28
Abstract: The electric switch is particularly for use inside motor vehicles. It has a housing (2) for a contact arrangement (3). The latter can be switched between at least two switch positions by means of a movable actuating member. A locking element (11) is arranged in the housing (2). This moves against a return force. The locking element (11) engages in the path of movement of the actuator to lock it into one switch position. A further actuator element (14) moves the locking element (11) out of the path of the actuating member to unlock the latter. The actuator element (14) and the locking element (11) are formed as two individual elements, separated from each other. The actuator element (14) is movable for its operation in a direction different from that of the locking element (11) and is thus brought into operative connecting with the locking element (11). The locking element (11) is thus moved to the unlocking position in response to the movement of the actuator element (14).
