Abstract: L'orientation de cristaux liquides (5) change à proximité de la surface d'une couche guide d'ondes (4) sous l'effet d'un signal de tension appliqué à travers une mince couche conductrice (2) et une mince couche conductrice transparente (6), modifiant l'indice de réfraction des cristaux liquides (5) par rapport à la lumière (8) guidée et l'indice de réfraction équivalent de la lumière guidée (8). La lumière (9) qui rayonne à travers la couche guide d'ondes (4) à structure périodique (3G) modifie par conséquent son angle de déflexion et se polarise. En outre, si la structure périodique (3G) est de forme concentrique, si la lumière guidée (8) se propage en angle droit par rapport à la structure périodique (3G) et si la lumière (9) qui rayonne à travers la couche guide d'ondes (4) est focalisée en un point (F) à l'extérieur de la couche guide d'ondes, la lumière rayonnante (9) défléchie par le signal de tension appliqué à travers la mince couche conductrice (2) et la mince couche conductrice transparente (6) provoque le déplacement du point de focalisation (F). On peut notamment déplacer le point de focalisation (F) jusqu'à n'importe quelle position en subdivisant la mince couche transparente (2) ou la mince couche transparente conductrice (6) en plusieurs zones et en appliquant indépendamment le signal de tension à ces différentes zones.

Abstract: The insulation-piercing terminal elements (8, 10) of the contact components (5, 6) for the incoming lines are led out on one longitudinal side of the distribution block (34) and the insulating- piercing terminal elements for the outgoing line wires are led out on the longitudinal side of the distribution block (34) opposite thereto. The other end regions of the contact components (5, 6) in each case have contact terminals (7) by means of which an electrical connection is produced which can be separated. A duct-like wiring space is bounded internally by one longitudinal side of the terminal distribution block. Said wiring space is divided by a transverse web, at right angles to the longitudinal side, into in each case one wiring space on the operating side (3) and one on the system side (4). As a result of the special design of the contact components (5, 6) and as a result of their insulation-piercing terminals (8, 10) being led out on both sides, the space which is required for housing the contact elements (5, 6) is particularly small, even in the case of a multi-row arrangement.

Abstract: 1.2. The invention concerns a compound fabric for use as papermaking machine wire-cloth, consisting of a first or upper fabric and a second or lower fabric, arranged one above the other and held together by binding threads. 
<??>2.1. The principal disadvantage of single-ply or double-ply wire-cloths whereby those properties which determine the surface quality of the paper, namely the absence of marking, and those properties which are crucial for the stability of the wire-cloth fabric, namely the elimination of relative movement of the fabric plies, are insufficiently, if at all, in harmony with one another, is to be eliminated. 
<??>2.2. This is achieved when the binding threads form part of the wound structure of the plies, a first thread being interlaced with the, relatively speaking, transverse threads of the first fabric in the weave pattern of this fabric over at least one repeat length and a second thread being interlaced with the, relatively speaking, transverse threads of the second fabric over at least one repeat length, and the first thread and the second thread crossing each other repeatedly within the body of the fabric, and, furthermore, the first thread being interlaced with the, relatively speaking, transverse threads of the second fabric in the weave pattern of this second fabric over at least one repeat length while the second thread is interlaced with the, relatively speaking, transverse threads of the first fabric in the weave pattern of this first fabric over at least one repeat length.

Abstract: An Equalizer (11) with adaptiv viterbi analyser (VIT1) and channel estimation circuits (CEST1,...CEST16), connected to each a state (1,...16) of the viterbi analyser (VIT1). The equalizer (11) recieves a signal (y(n)), which has been filtered and sampled at decided timepoints (n) and which during its transmission has been subjected to time dispersion. For each state (1-16) the estimation circuits (CEST1,...,CEST16) estimates each a part impulse response (C1(n),...C16(n)) for the channel. The estimation is iterative and comprises the steps: The viterbi analyser calculates transition error signals between an old and a new state with the aid of a preceding part impulse response. The viterbi analyser (VIT1) selects the best ones (ei,1...ep,16) of the transition error signals, old part impulse responses (Ci(n-1),...,Cp(n-1)) and transition vectors (Si1,...,Sp16). The estimation circuits (CEST1,...,CEST16) estimates the new part implulse responses (C1(n),...,C16(n)) for the new state (n) with the aid of the old part impulse responses (Ci(n-1),...Cp(n-1), the transition vectors (Si1,...,Sp16) and the transition error signals (ei1,...ep16). The part impulse responses (C1(n),...C16(n)) are utilized for estimation of symbols (S/< ANd >(n-L)).

Abstract: Threaded tubular interference fit interconnections and related production techniques are disclosed that are for example useful with large diameter tubular members, including pipe bodies, that can for example function as casing for oil, gas, geothermal, disposal and other wells. In a preferred aspect of the invention there is root-to-crest and/or flank-to-flank interference between nose and inner portions of male and female threads of the disclosed interconnections, such as substantially to seal them against leakage at the maximum internal and/or external pressure rating of the pipe body, and a run-out portion of the male thread and a corresponding portion of the female thread engage one another with interference to retain threaded engagement between said run-out and corresponding portions at the maximum axial force rating of the pipe body and also at the maximum internal and/or external pressure rating of the pipe body. These connections, when applied to API line pipe or other tubular products, can allow them to properly function as large diameter casing exhibiting easy and economical manufacture with existing machinery, easy installation in the field, good balance between geometric and load capacity transparency, and freedom from some undesirable characteristics of prior products.

Abstract: Portable detecting plates which are programmable by fields are used to identify persons, animals and objects. The data are exchanged without contact by means of coil coupling between a read/write device and the detecting plate. 
<??>To supply power, and also to transmit the data and program the fields, the new detecting plate uses one coil only. The data and commands required for field programming purposes are transmitted using pulse pause modulation to the detecting plates, where they are digitally evaluated. Since the data communication is not carried out with field synchronisation, an oscillator is used in the detecting plate to serve as a time reference. A buffer capacitor on the detecting plate supplies power in the pulse pauses during PPM modulation. The low-power digital modulation decoding together with the buffer capacitor allow a long read/write distance when the detecting plate is used.
