Abstract: Analytical photometer for the practically simultaneous determination of the presence of different substances in a certain number of discrete samples. The photometer (10) is equipped with a centrifugal type rotor (16), already known in the art, containing a large number of chambers with inlet holes (20, 22) for the sample/samples and reagents and with axially aligned transparent windows, thereby forming a system of rotating cuvettes (18). The rotor compartments (16) serve as receptacles for the solutions and are designed and dimensioned as already known in the art, such as to retain the liquid when said rotor (16) is at rest and to transfer said liquid into the cuvettes (18) when the rotor (16) rotates. A single or multiple light source (L) is provided, which is transmitted in a novel manner through a system of suitable means, in particular, optical fibres (30-35) to various photodetector units (60 to 65), suitably aligned with the transparent windows of the cuvettes (18) by means of the same number of interference filters (50 to 55) and appropriate holes (40 to 45) situated in the base (15) of the rotor (16). Thus it is possible to determine for the first time, concentrations of chemical solutions through the absorbance in the sample/samples plus reagent/reagents contained in the cuvettes (18) at various wave lengths, with wave energy being delivered from source (L). 
<??>Hence it is possible to examine more than one cuvette (18) almost simultaneously and singly, each one for a different analytical parameter, and consequently to examine the transmittance and/or absorbance of the samples contained in the cuvettes at optimum wave length.

Abstract: @ A method and apparatus for fault testing a clock distribution network (11) which provides a plurality of clock signal lines (25) to the logic networks (12) which comprise a data processor (10). The fault testing apparatus includes a decoder (24) for selecting one of the clock signal lines to be tested, and a test latch (40) which is clocked by the selected clock signal line. The selected clock signal line is tested by setting the test latch to a first logic value (e.g., binary ZERO) and maintaining a second value (e.g. binary ONE) at the test latch input. If the second logic value is stored in the test latch when the clock distribution network is inhibited, then a stuck-on fault is indicated for the selected clock signal line. If the second logic value fails to be stored in the test latch when the clock distribution network is enabled, then a struck-off fault is indicated for the selected clock signal line. Each clock signal line in the clock distribution network may be tested in this manner.

Abstract: A double coupling comprising two flexible couplings are connected to each other through an intermediate hollow shaft and have outer parts on each and each with a hub and radially extending arms between which rubber blocks shaped as ring segments are inserted in a prestressed state. The rubber blocks each comprise a central, radially inwardly narrowing wedge to which two rubber members carrying plates on their free surfaces are symmetrically vulcanized on either side. The wedges are connected to corresponding claws of the intermediate shaft. The wedge and claws, along with the intermediate shaft serves as a common hub portion and form an inner part of the flexible coupling. One hub is secured to a solid shaft and the other hub is secured to a hollow shaft. The solid shaft extends through the hollow shaft and they move relative to each other, even in misaligned positions. As compared to similar prior art couplings for transmitting comparable power, the weight of such a doubling coupling is reduced.
