Abstract: A directgion indicating apparatus and method using a GPS receiver (10) with processor (14, 16), memory (18), input (20, 201) and indicator (22, 221, 222), uses conventional code pseudorange and carrier phase to provide a compass function. The receiver antenna (12) is desirably held stationary while the directional vectors toward the satellites and for the desired heading (21) are computed, the rate of change of carrier phase determined and future carrier phase predicted. The antenna (12) is then moved in a closed path (11) while the differences between predicted and actual carrier phase are measured and converted to positional perturbations which are resolved along the desired heading (21) and normal thereto. As the antenna (12) moves around the closed path (11), the resolved perturbations have maxima, minima or change sign and the processor (14, 16) uses this to trigger the indicator (22, 221, 222) so that the desired heading is apparent to the user (8).

Abstract: A digital filter characterized by the fact that the operation time of the filter can be kept short even when the order of the filter is high. The digital filter comprises a virtually transposition-type transversal filter TF 1  which has an input terminal connected to a signal input terminal 10, first delay means DR 1  which has an input terminal connected to the output terminal of first transversal filter TF 1'  a second virtually transposition-type transversal filter TF 2  connected to the output terminal of the first delay means DR,, second delay means DR 2  which has an input terminal connected to the output terminal of the second transversal filter TF 2 , adder AD which has one of the input terminals connected to the output terminal of the second delay means DR 2 , third delay means DR 3  which has an input terminal connected to the output terminal of the adder AD and an output terminal connected to the signal output terminal, and a virtually transposition form third transversal filter TF 3  which has an input terminal connected to the output terminal of the aforementioned third delay means DR 3  and an output terminal connected to the other input terminal of the aforementioned adder. In this type of digital filter, the chain configuration of the operator that determines the time needed for one cycle of operation is a multiplier-adder chain including one multiplier and one adder in each transversal filter having a transposition configuration. Consequently, its operation time is equal to the sum of the operation times needed by one multiplier and one adder and is unrelated to the order of each transposition type transversal filter, that is, the order of the digital filter.

Abstract: Une plaque poreuse utilisée dans une pile électrochimique est rendue étanche au moyen d'un mélange de matériau essentiellement actif à 100 % et d'un catalyseur. Ledit mélange est absorbé par les pores et remplit pratiquement le volume total de vide formé par ces dernières. Le mélange subit ensuite un choc thermique afin de le durcir partiellement et d'empêcher l'effet de mêche. Le mélange partiellement durci est ensuite soumis à un post-traitement qui consiste à augmenter la température de façon que le catalyseur provoque une polymérisation des radicaux libres. Etant donné que l'agent d'étanchéité est essentiellement actif à 100 %, aucun chemin de fuite ne se forme au cours du procédé de durcissement, et l'étanchéité finale est essentiellement assurée à 100 %.

Abstract: The invention relates to a process for separating oil-in-water emulsions by primary breaking of the emulsion with an organic cationic emulsifier, separation of the resulting two-phase system into an oil phase and a water phase and secondary breaking of the oil phase with a demulsifier. By means of the invention, a process of the type mentioned at the outset is to be created by which good separation of the emulsion and economic and environmentally-friendly reuse of the oil is possible. This succeeds by the secondary breaking being carried out with an anionic, water-soluble, alkaline emulsier and separating the oil phase treated with this emulsifier into oil, water and solids in a three-phase decanter. Such a process is particularly suitable for treating oil-in-water emulsions arising as cooling fluids in the metal-processing industry.
