Abstract: L'invention concerne un procédé de fabrication de produits cellulaires et de stratifiés à base de prépolymères furaniques anhydres, possédant des groupements OH libres, dans lequel on opère à la température ordinaire en utilisant comme agent de réticulation et d'expansion, du tétrachlorure de silicium et/ou de l'oxychlorure de phosphore en faibles quantités. Le procédé selon l'invention est caractérisé par le fait que l'on utilise comme prépolymères furaniques une combinaison d'une résine d'alcool furfurylique et/ou d'une résine furfural-phénol (phénol et/ou bisphénol A) avec une résine de bishydroxyméthylfurane, sans utiliser d'acide, le tétrachlorure de silicium et/ou l'oxychlorure de phosphore étant utilisés dans des proportions de 0,1 à 5% en poids par rapport à la résine mise en oeuvre. L'invention s'applique notamment à la fabrication de matériaux ayant une excellente résistance au feu et une excellente stabilité dimensionnelle à chaud ainsi qu'un bon pouvoir isolant. Les isolants, les mousses structurelles et les stratifiés fabriqués selon l'invention, en fonction de leur stabilité thermique et de leur ininflammabilité, peuvent être utilisés en tant que pare-feu dans la construction ou l'aviation, la carrosserie de tout engin mobile et les containers, en général.

Granted: 1986-09-23
Abstract: ABSTRACT           A power system includes an a-c power supply which constitutes a voltage source for a user of d-c current.  The a-c power supply is designed to generate an output voltage having a trapezoidal wave form.  This is achieved by generating a sinusoidal voltage and then suppressing the waves at a predetermined amplitude to obtain flat-topped voltage waves.  The edges of the trapezoidal waves representing the output voltage of the a-c power supply have slopes which equal or exceed the corresponding slopes of a sinusoidal curve having the same maximum amplitude and period as the trapezoidal output voltage.  The a-c power supply is further designed to maintain the mean or average value, as well as the maximum value, of its output voltage constant.

Abstract: ABSTRACT     A waveguide lowpass filter has successive groups of three separate ridges spaced longitudinally in said filter.  A centre ridge of each filter has a larger cross-sectional area than two side ridges which are the same size.  All ridges are parallel to one another in a longitudinal direction.  The groups are associated with shunt capacitances and the spaces between adjacent groups are associated with series inductances in an evanescent mode.  In operation, the filter is capable of supporting a TE10 mode in the passband  and three modes, TE10, TE20 and TE30 in the stopband.  The filter has a relatively high power handling capability as compared to previous evanescent mode lowpass harmonic filters.

Abstract: ELECTRONIC INCLINATION SENSING DEVICE                Abstract A device is disclosed for sensing information relating to the orientation of a selected direction or plane with respect to the horizontal. In one embodiment, the invention comprises a housing (40), a vial (70) mounting in the housing, a source of electromagnetic radiation (62, 64), sensors (66, 68) and associated electronic circuitry, and a rail (12) for positioning the housing. The vial is elongated along a central longitudinal axis and is partially filled withliquid (72) to form a bubble (74) in the vial. The source of radiation is positioned in a housing plane to one side of the vial such that radiation passes through the vial and forms a shadow of the bubble on the other side of the vial. The shadow is detected by the sensors, and the associated electronic circuitry produces an output signal having a characteristic related to the bubble position along the longitudinal axis. The rail is adapted to position the housing with respect to aselected direction such that the housing is vertical and the orientation of the longitudinal axis of the vial with respect to the selected direction is known. The electronic circuitry is preferably adapted to produce an output signal corre-sponding to the difference between the signals provided by the sensors. A further embodiment is disclosed that is capable of sensing information relating to the orientation of a selected plane. In such further embodiment, the bubble (230) is contained in a chamber (226) beneath an inwardly concave upper wall (228), and the shadow (240) of the bubble is projected onto a two-dimensional sensor array (234).

Abstract: ABSTRACT OF THE DISCLOSURE:           One of patterns (22) representative of instants along each TDMA frame is selected as a selected pattern (24) in response to a unique word detection pulse produced in a current frame.       With the unique word detection pulse used as a write pulse (27), a memory (25) memorizes the selected pattern as a memorized pattern in a memory cell accessed by one of burst identifying flags which identify time slots in the current frame, respectively.  The memorized pattern is produced as a read-out pattern (28) when accessed by the burst identifying flag which corresponds in a next succeeding frame to the above-mentioned one burst identifying flag.  A calculator (31) produces offset representing patterns (32).  Upon coincidence of each read-out pattern and one of the offset representing patterns, a comparator (33) produces a receive position predicting pulse predictive of a position of a unique word detection window in the next succeeding frame.  The write pulse is preferably obtained by giving the unique word detection pulse a delay which is equal to a predetermined fraction of each time slot.  The offset representing patterns represent the respective instants plus an offset which is equal to a duration of each frame minus a half of a duration of each unique word detection window.

Abstract: ABSTRACT OF THE DISCLOSURE      A wedge anchorage for an axially elongated tension member, encased in and arranged to prestress a concrete structure, includes an anchor member with a conically widening surface where a wedge seats for securing the tension member in the tensioned state with a cap arranged to fit in locked engagement with the end of the anchor member through which the tension member extends out of the concrete structure.  The cap has  a cover wall extending transversely of the axial direction and spaced from the anchor member.  An opening is provided in the cover wall through which the tension member extends out of the concrete structure.  A spring or other biasing member is located within the cap for limiting axial displacement of the wedge when the tension member is stressed in tension.  This arrangement avoids the formation of a recess in the surface of the concrete structure from which the tension member extends and the need for a filler member for sealing off the recess when the pre-stressing operation  is completed.
