Abstract: In order to adapt the throughput of the transmission to the unknown quality of the transmission path, a test message is transmitted (101), the content of which is that of the start of the document to be transmitted and, on reception, the content of the test message received is saved, and the error rate in this message is determined by a method insensitive to its content. In the event of acceptance (102) just the remainder of the document is transmitted (103). In the event of refusal (102), another test message, of lower throughput, is sent (105, 101), and so on. The invention makes it possible to reduce the total duration of transmission of a document by fax. <IMAGE>

Abstract: The invention relates to a system which can be fitted to a chair, in which deformable, especially inflatable, elements (4, 5, 6, 8, 9, 10), whose passage from a retraction state to an expansion state and vice versa involves well-defined sequences of movements of the human body, are in communication with a circuit (30, 23, 32, 33) and a source of power, especially of pressurised fluid (22), comprising control means (40, 41) placed under the dependence of a programmer (42) automatically ensuring alternate phases of expansion and of retraction which give rise to stress displacements in human joints and tissues in general, a stabilisation of the human body, in itself and relative to the chair, and a stimulation of a reflex activity of tonic muscles. This programmed-dynamism system aims to periodically assist the user in getting up more easily from the chair in order more easily to subsequently readapt thereto in order to obtain greater comfort and to maintain his alert state. <IMAGE>

Abstract: There is described a dispensing pump for a fluid contained in a container, in which the component parts form two units which are functionally joined together by a coupling member (26), while being easily separable. The component parts of each unit are assembled together in such away as to make them hardly separable. The second unit comprises a valve (56) for communication with the container (28) and is inseparably attached to the container (28) and is further provided with a device restraining access to the valve (56), whereby this unit acts as a seal for the container. The first unit comprises a cylinder (2), piston (6), actuator means (14), spring (16) and communication means (8, 12) with the external environment and is applicable to successive second units.

Abstract: An irrigation controller is powered for all normal operations by light incident upon an 18 square inch photovoltaic module. Electrical power from the photovoltaic module is stored in high performance "super" capacitors. A transportable battery power source is connected to the controller to power its communication, such as for manual exercise and/or the loading of irrigation control programs. The external battery power source leaves the capacitor power storage recharged at the conclusion of each communication episode. The irrigation controller electronics, save for a real time clock that is updated, are not provided with a timing signal, and thereby consume almost no energy, save for brief millisecond sporadic time intervals of scheduled irrigation control. Capacitor power storage is approximately 6.5 mWH. Worse case photovoltaic energy production is 7.6 mWH daily. The sporadically operative irrigation controller uses less than 6.4 mWH per day, with remaining energy expended on up to 128 ultra-low-power valve actuations per day.

Abstract: A regulating circuit for controlling the speed of a rotating disc to provide a constant frequency signal from the disc includes a signal pickup device which moves radially along the disc and provides a velocity signal the frequency of which changes by a factor (Delta)f as the position of the pickup device on the disc changes. A processor receives the velocity signal and produces a control signal in accordance with the factor (Delta)f. A change-over switch provides a fine range voltage and a coarse range voltage which are used to control the speed of the disc in a fine range mode and a coarse range mode, respectively.

Abstract: Dans le procédé de commande de profil décrit, qui sert à commander le profil d'une ligne de soudage dans une opération de soudage par tissage, un courant de soudage et/ou une tension de soudage dans la position adjacente d'un point de fin de tissage est déterminé comme valeurs de référence. Après avoir mesuré un courant de soudage et/ou une tension de soudage à proximité du nième (n » 2)point de fin de tissage, on détermine la position du (n+1) ième point de fin de tissage sur la base de la différence entre les valeurs observées et les valeurs de référence. On exécute ensuite le soudage depuis le nième point de fin de tissage jusqu'au (n+1) ième point de fin de tissage sur la base de ces données de position. Ainsi, on peut réaliser une soudure par tissage correcte.

Abstract: The measuring instrument has a housing (1) with an access opening (7) for the hand of the person whose tendency to perspiration is to be measured. Arranged behind this opening (7) is a measuring device (12) which has on the surface measuring elements for measuring the skin resistance. The measuring elements are connected to evaluation electronics. During the measurement procedure the person in question passes a hand through the access opening (7) and grips the measuring device (12). The measuring elements thus come into contact with the skin surface and measure the skin resistance. The heat level of the body is reflected in the skin moisture, so that it can be used as a measure of the thermal state of the individual. The measured values determined by the measuring elements are evaluated by the evaluation electronics and displayed. In this way, the subjective reaction of the individual to heat stimuli can be determined very simply and accurately. <IMAGE>

Abstract: A cascode mirror video amplifier for generating equal amplitude and opposite phase signals for driving a cathode and control grid of a cathode ray tube. The video amplifier comprises a pair of common base amplifiers (1, 7) connected via equal valued resistances (12, 14) to a pair of opposite polarity power sources (10, 16). A common emitter amplifier (3) is connected intermediate the pair of cascaded common base amplifiers (1, 7) and functions as a voltage control current source for receiving an input signal and in response generating a common current signal within each of the pair of common base amplifiers (1, 7) such that equal amplitude and opposite phase voltage signals are generated across the respective resistances (12, 16). A pair of emitter follower stages (5, 9) apply the voltage across the resistance pair (12, 14) to the electron source cathode and control grid respectively while isolating the load capacitance of the cathode ray tube from each of the common base amplifiers (1, 7). <IMAGE>

Abstract: The apparatus for turning by 90 DEG  a panel or a panel stack (P) on the cutting machine worktable (Q), comprises a withdrawable gripping means (1) which can be rotated around a vertical axis (2), and upon control is caused to clamp a panel stack (P) close to one of its rear corners. The gripping means (1) is associated with shifting means (7) for the gripping means (1) to be caused to perform in a programmable precise manner a rectilinear movement (3) near to, and away from the cutting line (Z) of the longitudinally cutting machine, such that the panel stack (P) will be turned in clockwise or anticlockwise direction, depending on the panel stack (P) being clamped at its left-hand or right-hand corner. Thus, any cutting pattern, such as a cutting pattern with a pre-cutting operation, for which a panel stack (P) needs to be turned by 90 DEG , can be then carried out. A withdrawable pushing means (4) is caused to act on the panel stack (P) concurrently with the gripping means (1), by being moved parallel to the longitudinally cutting machine in a programmable precise manner, so that it helps in the desired turning of the panel stack (P). Differently from the known art, a lesser floor space is here occupied by the conventionally constructed worktable Q for supporting a panel stack as it is being turned by 90. <IMAGE>

Abstract: L'invention concerne les tubes électroniques de puissance à grille. Pour de fortes puissances et des hautes fréquences un échauffement très important et localisé de la grille se produit sous l'effet des courants élevés. C'est le cas par exemple pour la grille-écran (grille G2) des tétrodes à grille maillée à barreaux verticaux ou obliques (20, 22) en graphite pyrolytique. Pour améliorer la fiabilité de fonctionnement et la durée de vie du tube, on propose selon l'invention de donner aux barreaux de la grille une largeur plus importante dans le bas de la grille, là où les courants haute fréquence sont les plus importants.
