Abstract: A process for controlling a vessel annealing treatment in which a heater unit assembly (2,4,6,8,10,12) composed of a plurality of electric heater units (6) is disposed in a vessel such that each heater unit (6) is in facing relation with a respective zone of the vessel, the heater unit assembly (2,4,6,8,10,12) being composed of a plurality of regions each containing a respective plurality of heater units (6), by the steps of: supplying electric current to each heater unit (6) for causing the heater unit (6) to deliver heat energy to the vessel; in­dividually sensing the temperature of each zone of the vessel and producing a representation of each sensed temperature; deriving a representation of the temperature of each zone of the vessel by mathematically combining the sensed temperature representation of each zone with the sensed temperature representation of all other zones associated with the same region; at least periodically determining the quantity of heat to be produced by each heater unit (6) on the basis of the temperature representation derived for the zone with which that heater unit (6) is in facing relation; and adjusting the level of current supplied to each heater unit (6) on the basis of the results produced in the determining step.

Abstract: The present invention relates to reinforced pressure-­sensitive adhesive tapes, and to a method for making these tapes. Reinforced tapes, also known as filament tapes, generally comprise a backing having adhered to one major surface thereof by means of an adhesive a plurality of yarns, which comprise a multiplicity of glass or synthetic polymeric filaments. Typically, a layer of pressure-sensitive adhesive is then applied over the yarn- or filament-bearing surface of the tape. Although filament tapes are extremely useful, the cost of making them is high because of the high cost of filaments and the high cost of processing. In order to reduce the cost of making filament-reinforced tapes, some manufacturers have resorted to reducing the number of filaments adhered to the backing. However, this expedient reduces the tear strength of the tape. It is desired to have a tape having a reasonably high level of tear strength, but at a much lower cost than that of high quality filament-reinforced tapes. This invention provides a tape comprising a backing bearing on at least one major surface thereof a plurality of ribs disposed substantially longitudinally thereon, and further bearing on at least one major surface thereof a layer of adhesive. The ribs are joined to the backing such that there exists a notch-like separation between each end of the rib and the surface of the backing. No more than 50% of the cross-section of the ribs should project from the rib-bearing surface of the tape. It is preferred that the adhesive be a pressure-sensitive adhesive. The tape of this invention can be prepared by means of coextrusion techniques.

Abstract: La mesure de la stabilité en émission-réception d'un radar (RAD) comprend deux étapes. Au cours d'une première étape, des signaux de tension vidéo (I, Q) sortant d'un détecteur de phase (DP) du récepteur du radar (RE) sont mesurés à des instants ssignificatifs où lesdits signaux sont susceptibles de subir des fluctuations, ces signaux étant issus d'un signal réfléchi par une cible fixe (CF) et reçu par le radar. Au cours d'une seconde étape, un signal supplémentaire (SS) de phase et d'amplitude prédéterminées est superposé au signal reçu (SR) dans le récepteur (RE) afin de sensiblement annuler les parties stables des signaux de tension (I, Q), et de mesurer les fluctuations des signaux de tension ainsi obtenus auxdits instants significatifs. L'appareil (AM) pour mesurer ces fluctuations comprend avantageusement des convertisseurs analogiques-numériques à faible nombre de bits.

Abstract: For arithmetic coding of symbols in a linear pattern or in a two-dimensional pattern, the position of each symbol is determined to be either a predictable point (PP) or an unpredictable point (UP), depending on the context (C1). For predictable points, normal arithmetic coding is used. For unpredictable points which would require relatively much information to be added to the coded output, a special procedure is applied to reduce the required amount of information. Either, instead of encoding the particular symbol appearing in an unpredictable point, a whole preselected set of symbols containing the particular symbol is encoded; or, for an unpredictable point, the context is changed (C2) to thus render the point predictable.

Abstract: A reverse-phase HPLC method is disclosed which allows the separation of DPU and PTH-Trp and, therefore, the correct assignment of tryptophan residues in an amino acid sequence. The method is based on a modification of the conventional HPLC gradient commonly used to elute and separate all PTH amino acids of interest in automated and manual sequencing. In one embodiment, using automated instruments manufactured by Applied Biosystems, gradient modification is achieved by changing the manufacturer-supplied gradient program which controls the operation of the HPLC pumps in the instrument. Using the methods of the present invention, the correct and reliable assignment of tryptophan residues is possible and was reproducible over time, even with small sample sizes.

The central station includes a correlator which is synchronized with the central station's chip-rate clock pulses to detect correlations between the pseudorandomly modulated data bits a sequence of pseudorandom numbers corresponding to the PN sequence bits of the terminal stations.

Abstract: In a dual distributor for a VHF/UHF band having in each case one matching and differential transformer (AÜ, DÜ) in each case exhibiting a winding with a tap, the taps being conductively connected to one another, and a decoupling resistor inserted between a connecting point (P), which is optimal for achieving the greatest possible decoupling, of the matching transformer (AÜ) and one of the two outputs (A2), this decoupling resistor is a complex impedance (Z = X + jY), the frequency-dependent resistance (X) of which, forming the required ohmic decoupling resistance, compensates for the loss resistances and the reactance (Y) of which compensates for the main and stray inductances of the two transformers (AÜ, DÜ) over a wide bandwidth. This compensation makes it possible to determine the compensation current flowing through the complex impedance in such a manner that a high coupling loss exists between the two outputs (A1, A2) over a wide bandwidth. The magnitude of this coupling loss, of the bandwidth and of the circuit complexity can be adapted to the individual case by approximating the frequency response of the complex impedance to the nominal frequency response which is essentially mathematically determined. <IMAGE>

Abstract: In fittings for the detachable connection of two plates, having an approximately cylindrical clamping part which holds the head of a tightening bolt in a recess (7) having an insertion opening (11), a clamping slot which is open on one side being provided over a part of the circumference of its side wall, the assembly of the plates is relatively difficult, since they must be held by hand or by additional aids until the clamping process is completed. In order to achieve a temporary connection of the parts by a latching connection between the clamping part and the tightening bolt, the clamping part has an elastic constriction (12) which reduces the insertion opening (11) below the size of the head diameter of the tightening bolt. When two plates are being joined, the tightening bolt is inserted with its head into the insertion opening (11) of the recess (7) and hence spreads the elastic constriction (12) apart, which then narrows again once the head has passed through so that the tightening bolt is secured against sliding out.
