Abstract: A moveable roof for waste dumps is composed of roof elements (2) which are mounted directly on the dumping level of the dump and can be easily moved. As a result, the necessity of complex roof structures with large spans which cover the entire dump and thus require appropriately heavy foundations is eliminated. The roof elements (2) are preferably gable-shaped and lie on support carriers (1) which lead off water in gutters. Drainage channels receive the water from several gutters and carry it to one or more pump sumps from which it is pumped off. The roof is easy to assemble and disassemble and can be adapted to different local conditions. The upper surface of the support carriers can be walked on. <IMAGE>

Abstract: An optical transmittance apparatus has a pair of reference channels of glass rods and a pair of sam - ple channels containing sample fluid. A beam splitter and mirror pass a first portion of an incident beam through an ingoing reference channel, and a second portion through an ingoing sample channel. The first portion is reflected back through an outgoing refer - ence channel, and the second portion back through an outgoing sample channel. The beam splitter and mirror directs the outgoing beams into a common outlet path. A partial disk selectively passes either portion. For positioning the disk, poles of a magnet mounted on the disk axle face windings made about an axis perpendicular to the axle, the windings being on the opposite side of a barrier plate from the poles. Current of one polarity through the windings effects one orientation of the disk, and reversed olarity reorients it perpendicularly.
