Abstract: 1. A process for the quantitative determiantion of a dissolved optically active substance in aqueous or non-aqueous solutions by means of polarimetry by splitting the light beam after the sample by means of a beam splitter, thereby producing a measuring beam and a reference beam, and forming a difference or quotient signal of the signals of the measuring and the reference beam detected by corresponding detectors, whereby the polarized light of the light source prior to passing through of the sample is eventually subjected to frequency, phase, or amplitude modulation, and the difference or quotient signal formed of the signals of the measuring and the reference beam is demodulated correspondingly, characterized in that for simultaneously obtaining beam splitting and an analyzing effect the light beam after the sample is directed to an optical interface at an incidence angle (alpha) between the polarization angle and the limit angle of total reflection.

Abstract: The present invention relates to a reaction vessel adapted to withstand pressures and temperatures of the magnitude associated with the manufacture of diamond products and boron nitride (BN) and similar hard materials. The reaction vessel has an outer chamber or shell formed from steel and an inner reaction chamber. Known vessels of this type must be provided with a thick layer of insulating material between the reaction chamber and the outer steel shell to protect the outer shell from the heat of the diamond-forming process carried on in the reaction chamber. The quantity of insulating material required within the vessel for adequate protection of the outer shell is relatively large as compared to the area of the outer shell. Accordingly, the amount of available space remaining within the vessel for the diamond-forming reaction is limited, thus limiting the size of the diamonds formed. The present invention provides a reaction vessel with a cooling system which eliminates the need for the large quantity of insulating material in the known vessels. As such, the reaction vessel provides a significantly larger reaction chamber for the diamond-forming process, and the resultant diamonds are up to a thousand times larger than those formed from known reaction vessels. In one embodiment of the invention, the cooling system includes a plurality of truncated steel pyramids arranged to form flow passages or channels for a cooling fluid adjacent to the inner wall of the vessel's outer steel shell to absorb and disperse heat before it penetrates the outer steel shell.

Abstract: A drill screw for drilling through soft packing material such as timber into a steel purlin has a drill point (12), a , threaded shank (11) and a head (13). The srew thread (14) is interrupted by longitudinally extending flutes (19) otherwise adapted to become at least partially filled by loose packing material generated by drilling so that the thread tends to ream out the packing material and prevent an effective threaded connection between packing material and drill srew. This allows the drill screw to advance at the normally required slow advance when the drill point engages the purlin.

Abstract: VLSI chips contain a very high density of logic elements and have only a limited number of pin connections making complete testing by conventional means impracticable. 
     The invention provides a self-verifying chip. The chip includes a data processing chain (10) and a plurality of fault detecting circuits (13,14,15) coupled to the data processing chain. A plurality of internal stimulus generators (18,19,20) generate test signal patterns in response to a supervisory control (21) which are applied to intermediate points of the data processing chain. Outputs from the fault detecting circuits (13,14,15) are applied to an error status generator (16) which provides error signals indicating fault conditions at various points of the data processing chain. Fault detecting circuits (18A.21A) may also monitor the internal stimulus generators and the supervisory control means. 
     The devices of the data processing chain may normally operate in a parallel-load mode, but may be loaded with the test signal patterns in serial mode. 
     The chip may include duplicate functional or complementary logic for the data processing chain, and the fault detecting circuits may be arranged to check the operation of the two logic chains against each other. 
     A number of chips according to the invention may be mounted on a card, with a card fault detector receiving the outputs of the error status generators of the chips and providing an output indicating the faults detected in the chips and in the card wiring, and, in turn, in a complete system the outputs of the card fault detectors may be applied to a system fault generator monitoring the occurrence of faults in the whole system.

Abstract: Dans la dérivation de pompe d'un amplificateur paramétrique qui en comporte trois, montées aux bornes d'une capacité non linéaire C(V), on monte un dipôle (D) à résistance négative, capable d'osciller à la fréquence fp; on adapte les deux autres dérivations, l'une sur un circuit résonant (Cs), à forte surtension à la fréquence fs et l'autre, sur une impédance de charge, celle d'un circuit (CO) résonant, à la fréquence fo. On a fo = fp - fs. Moyennant certaines conditions d'impédance, on recueille un signal à haut niveau sur fo. L'intérêt est que fo peut être sensiblement plus élevé que fs, par exemple 35 GHz contre 10 GHz.
