Title: Dispositif pour la reconnaissance d'une frequence dans un signal telephonique code en mic
Inventor: LUDER JACQUES
IPC: H04Q1/448
Filed: 1978-06-08
Granted: 1981-10-27
Abstract: L'invention se réfère à un dispositif de reconnaissance numérique d'une fréquence dans un signal MIC. Selon l'invention, on prévoit un compteur/ décompteur qui reçoit a impulsions de comptage lorsque le signal à contrôler présente un changement de signe, et qui reçoit r impulsions de décomptage lorsque ce signal ne présente pas de changement de signe. Les nombres a et r sont déterminés en fonction du rapport entre la fréquence d'échantillonnage du signal MIC et la fréquence à reconnaître, de telle sorte que l'on puisse déduire la présence de cette fréquence d'un équilibre entre le nombre des impulsions de comptage et le nombre des impulsions de décomptage. Application à la reconnaissance de la tonalité de neutralisation pour un suppresseur d'écho dans une ligne téléphonique MIC.

Abstract: METHOD AND APPARATUS FOR SEPARATING WHOLE BLOOD INTO COMPONENTS THEREOF AND FOR AUTOMATICALLY COLLECTING ONE          OF THE COMPONENTS      ABSTRACT OF THE DISCLOSURE    The method, and the apparatus for carrying out the steps of the method, are utilized in the centrifugal liquid processing of whole blood wherein whole blood is withdrawn from a donor, passed through a fluid system and the blood is centrifuged to separate the same into at least three components.  One component which is to be collected is withdrawn at a fixed rate of volumetric displacement while the other two components are withdrawn at variable rates of volumetric displacement.  The other two components are recombined and returned to the donor.  The withdrawal of the one component is optically monitored to determine whether or not either one of the other components is being mixed with the one component.  When such a mixing is sensed, the rate of withdrawal of one of the other two components is increased while the rate of withdrawal of the other components is decreased thereby to ensure with-drawal of the desired one component, e.g., white blood cells with minimal contamination thereof with the other two components, e.g., red blood cells and plasma containing platelets.  A given amount of the one component withdrawn is collected in a receptacle.

Abstract: Abstract of the Disclosure Leg structure for portable, height-adjustable gantries is disclosed having an upper, single vertical tubular post member telescopingly received within an open-ended sleeve formed by coupled aligned channel members of lower, break-apart sectional supporting framework.  The channel members are supported and elevated by diagonal bracing members and struts giving a generally inverted-Y shaped configuration to the leg so that it can straddle objects and permitting the free, unobstructed downward passage of the post through the lower opening of the sleeve.  A locking bolt passes through aligned holes in the post and channels to selectively hold their relative positions, with hand-operated winch means aiding the movement of the post.  Post extension members are disclosed which can be added to the leg post while the gantry is assem-bled.  The plate connection between the top of the post and a load-supporting I-beam is externally and internally braced by triangles and post weldment of casting insert-elements, respectively.  Alternative embodiments show plate and tubular spacer channel coupling arrangements, and solid post-to-frame and non-breakdown frame leg configurations.

Granted: 1982-09-14
Abstract: ABSTRACT OF THE DISCLOSURE        An alloy comprised of 45 to 53 wt. % Ni with the remainder iron, and including small amounts of deoxidizing and processing additives is worked into a 0.01 to 0.1    thick tape, wound to form a tape core and is then subjected to a final annealing for at least one hour at a temperature of at least 900°C and thereafter is subjected to a tempering in a magnetic cross-field (i.e., the magnetic lines of force are applied in the plane of the tape perpendicular to the rolling direction thereof). The process provides high impulse permeabilities at induction rises of 1T or larger within the so-processed tape cores.  Particularly high impulse perameabilities are achieved in instances where an anisotropic structure with a privileged grain direction <001>  in the rolling direction is generated in the tape material via heating and final deformation before winding into a tape core and via a final annealing after winding of the tape core.  The so-produced tape cores are useful in various electrical applications, particularly in pulse transformers and thyristor choke coils.

Abstract: A B S T R A C T         A digital transmission system for time division multiplexed transmission of multiple digitized telephone or similar signals is disclosed. The system achieves frequency band compression comparable to the conventional Digital Speech Interpolation system while eliminating the possibility of echo. An input circuit receives the input signals, converts them to linear  signals as necessary and supplies them to a code converter where the digital signals are subjected to high efficiency code conversion such as adaptive differential P.C.M. with one bit or a greater number of variable bits based on code-converting-bit-number (C.C.B.N.) information supplied from a bit-number-assigning circuit.  The output of the code converter is passed through a selection circuit to a multiplexer and to CCBN information of each channel is also sent to the multiplexer.  A timing circuit supplies timing signals to all of the above named circuits.

Abstract: ABSTRACT           High purity ammonium pentaborate or boric acid is produced from alkali metal and alkaline earth metal borate ores by a relatively non-corrosive technology requiring low energy, without polluting the environment, by treating finely ground borate ores with ammonia and sulphur dioxide or ammonium sul-phite in the presence of methanol.  Useful by-products, such as sulphites, or fertilizers, such as ammonium phosphates, can be obtained.  If the ore is rendered anhydrous prior to treat-ment, there is produced methylborate-ammonia adduct which upon hydrolysis is transformed into ammonium pentaborate and boric acid.

Abstract: PROCESS FOR CONTROLLING PULP WASHING SYSTEMS                 ABSTRACT OF THE DISCLOSURE         A method of controlling the amount of a liquid shower flow introduced onto a slurry mat such as a pulp mat which is undergoing incomplete liquid separation on a vacuum filter drum.          The flow rate of the liquid being discharged with the slurry mat is determined by a capacitance measurement which is taken after the slurry mat has passed to a point on the filter means where liquid separation no longer occurs.  The shower flow is controlled by a correlation of the flow rate of the liquid in the slurry mat with the rate of slurry mat transfer from the vacuum filter drum and the necessary liquid shower flow as expressed by a dilution factor.       The present control system may be combined with secondary apparatus to measure the flow rate and thickness of the total slurry mat in order to determine by correlation the slurry mat consistency, the rate of solid material produc-tion from the slurry mat and the amount of air contained in the slurry mat.

Abstract: ABSTRACT OF THE DISCLOSURE Cationic, cross-linkable acrylic-polyester emulsion binder rosin systems are described which are useful as adhesives for binding organic metal, and glass filaments to each other and to various substrates in the preparation of reinforced composites.  These novel binder resin systems are derived from copolymerized ethylenically unsaturated monomers having pendant non-functional, cross-linking functional, and cationic groups.  The cationic polymer emulsions are particularly useful when thery are cross-linked with polyester resin polymer chains such as those formed by condensing unsaturated dicarboxylic acids with polyols and which can be applied as stable aqueous emulsions.
