Abstract: Cette source comporte un modulateur à électroabsorption recevant une onde lumineuse continue fournie par un émetteur laser. La courbe caractéristique de réponse de ce modulateur présente un seuil de sorte que ce modulateur transmet une impulsion optique (LP) de durée inférieure à celle d'une impulsion de commande électrique (EP) qui lui est appliquée par un générateur de commande. Des impulsions optiques du type soliton ainsi obtenues sont transmises par une fibre de ligne jusqu'à un récepteur. La présente invention peut être appliquée aux transmissions optiques.

Abstract: There are provided methods for producing solid anhy-drous methylolhydantoins.  Initially, an aqueous stirrable medium is dehydrated and heated to yield a substantially anhydrous stirrable melt.   The aqueous stirrable medium includes  (A)  a solute   selected  from  the  group  consisting  of   (i)   a dimethyloldimethylhydantoin,  (ii) a hydantoin reactant,  (iii) a formaldehyde source reactant, or (iv) a combination of any of the foregoing; and (B) optionally a catalyst.  A molten system is then provided by adding,  to the stirrable melt,  a reactant mixture which includes (A)(i) the same or a different hydantoin reactant,  (ii)  a substantially anhydrous formaldehyde source reactant which may be the same as or different than the formalde-hyde source reactant, or (iii) a combination thereof; and (B) optionally, the same or a different catalyst; wherein the molten system includes (i) at least one hydantoin reactant and (ii) at least one dehydrated formaldehyde source reactant or substan-tially anhydrous formaldehyde source reactant.  The at least one hydantoin reactant and the at least one dehydrated formaldehyde source reactant or substantially anhydrous formaldehyde source reactant in the molten system are reacted, while reaction water is removed, to yield anhydrous molten methylolhydantoin.  Final-ly, the molten methylolhydantoin is solidified.  Alternatively, solid anhydrous methylolhydantoin is produced by reacting, in an aqueous stirrable medium as above, a reactant mixture of (i) the same or a different hydantoin reactant,  (ii) a substantially anhydrous formaldehyde source reactant which may be the same as or different than the formaldehyde source reactant, or (ii) a combination thereof and (iv) optionally, the same as or different catalyst; wherein (i) at least one hydantoin reactant and (ii) at least one formaldehyde source reactant or substantially anhydrous formaldehyde reactant is present; while heating to at least the melting temperature of the methylolhydantoin and while removing substantially all water; to yield a molten methylolhydantoin; and subsequently solidifying the molten methylolhydantoin.   These methods can be practiced as batch processes or as semi-continuous processes.

Abstract: A device for encoding digital signals corresponding to images which are subdivided into blocks has a first encoding channel including a discrete cosine transform circuit. In addition to this first encoding channel the device has a second encoding channel which encodes the differences between the original coefficients present at the output of the discrete cosine transform circuit and the same coefficients after quantization and inverse quantization.        This second channel encodes the differences after they are quantized with a finer quantization step than in the first encoding channel. The device further includes a prediction channel including a motion compensation stage, that uses both the inverse quantized coefficients coded in the first encoding channel and the inverse quantized coefficients coded in the second encoding channel to produce a predicted digital signal. This predicted digital signal is subtracted from the digital signal to be encoded by the device.

Abstract: Dynamic channel allocation in an ISDN tine is implemented above a Level II  link layer protocol (LAP-D). The preferred embodiment comprises programming operating on a computing platform system including a communication coprocessor system. The programming includes a channel management module (CMM) (302) and a virtual channel module (VCM) (304) to implement dynamic channel allocation. The modules cooperate to control bandwidth between communication partners by selective allocation and deallocation of virtual B channels between them in response to preassigned priorities and real time events. Channel deallocation also takes place in response to high error rates in message transmission.

Abstract: A chair back has a back rest mounted upon a fastening member which is held in a desired vertical position upon a back rest carrier by a locking device. In the locking device an anchoring plate has shoulders bearing rearwardly upon the front of the fastening member, back rest carrier and a resilient clamp resistant device, the anchoring plate being provided at its rear end with an operating lever pivoted to the plate. Movement of the lever into a locking position brings pressure to bear upon the resilient device thereby compressing springs while clamping the fastening member to the carrier. The resilience applying member is located functionally between the resilient device and the lever to effect the clamping action.

Abstract: The invention relates to a method for determining characteristics of the flow of a medium in a channel by measuring the transit time of sound waves which are transmitted between one or more transducers, and determining the characteristics from the measured transit times.      In one embodiment of the method according to the invention, at least two sound waves whose transit time depends on swirl are transmitted along acoustic paths with a different sensitivity to swirl, and a measure of the swirl is determined from the measured transit times.      In another embodiment, at least two sound waves whose transit time depends on the symmetry of the flow profile are transmitted along acoustic paths with a different sensitivity to symmetry, and a measure of the symmetry is determined from the measured transit times.      These embodiments are preferably combined.      If weighting factors are allocated to the values obtained, the individual velocities of the sound waves can be used to calculate the average flow velocity and/or the throughput of the medium. Since allowance is made for possible disturbances of the velocity profile, the accuracy of the calculated variables is good.      The invention also provides for a device, by means of which the method according to the invention can be carried out.

Abstract: A method and apparatus for storing and retrieving multi-dimensional data in which a multi-level data structure is defined wherein one level contains those dimensions chosen by the user to result in dense data and the other level contains the remaining sparse data combinations. The dense dimensions specified in any given case are used to determine the basic block size used to store information. The remaining sparse dimensions are used to create the upper level structure which is used to point to the block which contains the desired information. Depending upon the sparseness of the data, different types of upper level structure may be used. Both the variable data block size and the choice of pointer structure may be used to balance the memory required against the speed of retrieval. Once the data structure is created, the data in the data blocks, and the pointers in one type of upper level pointer structure, may be retrieved by simple calculation of the offset of the desired cell in memory rather than requiring a search.
