Abstract: The convex housing (1) of the exterior light fixture is covered at its open underside by a detachably mounted transparent cover (2), the required kerf being in the horizontal plane. In order to form the kerf in a manner proof against spray and without an additional seal of special material, there is arranged on the housing (1) in the region of the kerf a circumferential rim formation (1a) which is inclined obliquely outwards, serves as the actual sealing surface (1b), and has an annular bead (1c), which is joined towards the outer rim and arches upwards, and which is joined by a free-standing rim (1d), which is directed downwards and engages over the rim (2a) of the cover (2). For its part, the cover (2) is provided circumferentially with a flange (2a) which is matched to the inclination of the sealing surface (1b) and bears directly against it. However, below the annular bead (1c) the flange (2a) is arranged in a freely standing manner and reaches up to a small gap (3a), also provided for tolerance compensation, virtually as far as the rim (1d). This results in formation below the annular bead (1c) of a prechamber (3) for spray that has gained access, which can settle therein and flow off once again through the gap (3a). In the case of a circular rim formation of the housing (1) and a round cover (2), the latter is preferably held by a plurality of bow-shaped wire springs (4) arranged in the housing. <IMAGE>

Abstract: A multichannel wavelength demultiplexer has two or more cascaded birefringent filter stages (45 and 47) for dividing an input signal (20) consisting of a plurality of adjacent channels of optical signals among a number of outputs, each of said filter stages (45 and 47) having a transmission function (83, 84, 85) with even symmetry about optical frequencies at the centers of both the longest and the shortest wavelength channels. This symmetry, common to all transmission functions, permits all birefringent filter stages (45 and 47) to be con­structed from sequences of the same one size crystal element, thereby greatly lowering the cost of construction because solely one size crystal element is fabricated, tested and assembled. A multichannel multiplexer, identical to the above defined demultiplexer, but operated in reverse, is set forth. A combination multichannel wavelength demultiplexer/ remultiplexer consists of a single birefringent filter stage (45) for use in conjunc­tion with multichannel multiplexer/demultiplexer to divide a common set of adjacent wavelength channels on its primary input between its primary and secondary outputs (51, 52) in any combination, and simultaneously to accept at its secondary input (25) different optical signals within the same wavelength channels as those exiting its secondary output (52) and recombine them to exit at its primary output (51), wherein said single filter stage has a transmission function (83-89) with even symmetry about optical frequencies at the centers of both the longest and the shortest wavelength channels. This symmetry, common   to its transmission function and to those of said multi­channel multiplexer/demultiplexer, permits all birefringent filter stages to be constructed also from sequences (54) of the same one size crystal element.

Abstract: Apparatus for isolating optical feedback in a laser interferometer having a laser light source (12) from which a linear polarised outgoing laser beam (28) of certain polarisation orientation is derived. The interferometer also redirects the outgoing laser beam to form a return laser beam (29) directed to a receiver (13). The outgoing and the return laser beams are physically close and are substantially parallel. The linearly polarised outgoing laser beam is converted to circular polarisation. A portion of the circularly polarised return laser beam directed toward the laser light source is converted back to linear polarisation with polarisation orientation orthogonal to the polarisation orientation of the outgoing laser beam. A portion of the circularly polarised return laser beam directed toward the receiver converted back to linear polarisation with polarisation orientation being substantially the same as the polarisation orientation of the outgoing laser beam. The portion of the return laser beam with polarisation orientation orthogonal to the polarisation orientation of the outgoing laser beam is directed away from the laser light source, and the portion of the return laser beam with polarisation orientation of the outgoing laser beam is directed toward the receiver.

Abstract: A fast method for sorting data in a distributed data processing system is disclosed. Each processor P i  12i locally sorts its data into a local sorted file S i  34i, simultaneously producing an index to the sorted data and a file of key data records R′ 32 each comprising a key value paired with the processor's identifier. Each processor produces a distribution table DT i  28i of its key values using the index, and sends the table to a coordinator processor 18 which merges the processors' tables into a global distribution table GDT 30. The global distribution table assigns subranges of key values to the processors, and is broadcast back to them. Each processor then sends each paired key value and processor identifier to the processor assigned by the global distribution table to handle the subrange containing that key value. The processors receive and merge the incoming key data records simultaneously as they send such pairs to other processors. An output stream V i  36i consisting only of processor identifiers is created by each processor from the merged key value and processor identifier pairs, and is sent to the host H 16, which merges it into a global output stream of processor identifiers. The processors simultaneously send their local sorted files S i  to the host, which reads records from them in the order specified by the global output stream V.
