IPC: H04L7/02
Filed: 1980-10-22
Abstract: A signal processing circuit for a signal varying in its properties, e.g., in its degress of distortion, in which the input signal is fed in parallel to two similar processing circuits e.g., equalizers, the characteristic of which can be varied by a control signal, wherein the control signal from the one processing circuit is periodically varied and the output signal is fed to a detector circuit which in optimum signal processing emits a trigger pulse to a holding circuit 52 which stores the corresponding control signal level, which is fed to the second processing circuit. A variable delay unit for the data is controlled by a continuously varying up-down counter, the contents of which continuously vary at the rate of a high frequency clock pulse. The direction of count and the time of the count is controlled by comparing the relative time-positions or phases of a timing pulse received with the data and a timing pulse generated at the receiver.

Inventor: WEBSTER DENNIS HUBERT
IPC: G01K11/26
Filed: 1983-11-29
Abstract: @ The temperature within a combustion chamber is gauged or estimated by analysing the noise within the chamber evoked by inherent sound generating properties of burners discharging to the chamber for resonant frequencies. Noise received by a microphone 6 (Figure 2) is converted to a fluctuating voltage and mixed with a reference signal at 18. The signal is processed in an amplitude comparator/subtractor 20 and time averaged to give a signal of amplitude varying in relation to frequency. From this, peak resonant frequency is derived and together with a knowledge of the velocity of sound within the combustion gases and the distance between opposed walls of the chamber, gives an indication of the temperature. Both the peak resonant frequency and the temperature signals may be displayed or used for control purposes.

Abstract: Un système d'exposition à répétition d'étapes incorpore un procédé permettant d'obtenir un alignement à haute vitesse des dés un par un de manière à accroître le rendement du système. Afin d'aligner les tracés du circuit devant être exposés sur une tranche de semiconducteur (10) par chevauchement, la tranche (10) est déplacée d'abord vers une position cible permettant de viser une cible d'alignement (24) formée au préalable sur la tranche (10), et est déplacée par la suite vers une position d'exposition. Le mouvement vers la position d'exposition est commandé en fonction de la position calculée de la cible d'alignement (24). Le procédé consiste à faire débuter le balayage vidéo pour viser la cible d'alignement (24) avant que le plateau (12) ne parvienne à un arrêt complet à la position cible. Les caractéristiques du mouvement du plateau (12) sont déterminées et on fait commencer l'acquisition des données vidéo aussitôt que l'oscillation du plateau (12) baisse d'une valeur acceptable. En faisant débuter suffisamment tôt le balayage vidéo, on obtient une diminution significative du temps d'alignementà chaque emplacement de dés.

Abstract: Locking springs (17) project from a plug body (11), and support bars (21) are axially movably held against the locking springs. The support bars axially engage a coupling sleeve (23) through engagement members. With the support bars in engagement with the coupling sleeve, the support bars are urged to move in a forward direction under the bias of a coil spring (22). When a plug is to be coupled to a socket, the support bars are caught by a front surface of a socket body, allowing the locking springs to be inserted into an insertion slot (35) in the socket body (34). When protrusions on the locking springs are inserted in recesses (38) in the insertion slot, the support bars are urged by the coil spring to be inserted into the insertion slot, and the protrusions axially engage in the recesses, whereupon the plug and the socket are locked together. When the coupling sleeve is pulled back against the bias of the coil spring, the support bars are withdrawn out of the insertion slot to allow the plug to be pulled out of the socket.

Title: Method for rolling foils from aluminium
Inventor: GUTTINGER HEINZ
IPC: B21B1/40
Filed: 1985-01-26
Abstract: In rolling metal foils, such as aluminum foils, especially very thin foils in the range down to 10  mu m, an improved uniformity of the foil thickness over the width of the foil sheet and, simultaneously, greater rolling speeds of the foil sheet are obtained by operating the rolling apparatus at a working point of the rolling force/material-working or line force/deformation characteristic curve which lies below the saturation region in which, while the material-working or deformation is nearly independent of the rolling or line force, the rolling or pulling speed is determined by other parameters and can not be varied. The thickness variations occurring under this selection of the working point and due to variations in the rolling or line force over the width of the rolls are compensated by regulating the rolling or line force such that the thickness reduction is constant over the width of the sheet or has a desired profile of variation. This can be obtained by, for instance, constructing one or more of the rolls as a controlled deflection roll provided with a series of pressure or support elements having regulatable pressing forces distributed over the width of the roll.

IPC: F23N1/02
Filed: 1985-06-29
Abstract: A steam-generator control method is proposed for controlling the mass flows of an oxidant and a fuel which are supplied for combustion. In order to control the flows at stoichiometric ratios with a required accuracy, the controlled variables are established by the measurements of the mass flows and their comparison with theoretically predetermined stoichiometric ratios. Measurement errors are defined continuously through a combustion-gas analysis, conducted by means of a probe after the combustion. The errors are used for the correction of the controlled variables. The time constant of the correction is smaller than the time constant of dynamic changes of the errors.

Abstract: Méthode de mesure d'azimut pour forage incliné. Pendant la rotation de la garniture de forage on mesure en permanence deux composantes du champ magnétique à l'intérieur d'un tronçon cylindrique de révolution de la garniture, ce tronçon étant constitué de l'acier ferromagnétique habituellement utilisé pour la réalisation de la garniture. Ces composantes sont mesurées par un magnétomètre 1 selon deux axes Ox et 0y perpendiculaires à l'axe Oz de ce tronçon et tournant avec ce dernier. A l'instant où la composante de l'accélération de la pesanteur est maximale selon Ox, un dispositif accélérométrique 11, 12, 13 commande le calcul et l'enregistrement du rapport des deux composantes mesurées du champ magnétique. A partir de la valeur ainsi enregistrée, de l'inclinaison de la garniture mesurée par ailleurs, et de l'inclinaison locale du champ magnétique, on calcule l'azmut de la garniture par rapport au nord magnétique. L'invention permet notamment la détermination permanente de la position d'un outil de forage au cours de la progression d'un forage incurvé.
