Abstract: Photopolarimètre permettant de mesurer simultanément la totalité des quatre paramètres de Stokes de la lumière. Le faisceau lumineux, dont l'état de polarisation doit être déterminé, frappe, selon des angles obliques d'incidence, les surfaces de trois photodétecteurs (D0, D1, D2) successifs, dont chacun reflète partiellement régulièrement la lumière et génère un signal électrique proportionnel à la fraction du rayonnement qui l'absorbe. Un quatrième photodétecteur (D3) est totalement photoabsorbant et détecte le reste de la lumière. Les quatre signaux de sortie ainsi développés forment un vecteur de signaux I(Boolean not) 4x1 qui présente une relation linéaire, I(Boolean not) = A(Boolean not) S(Boolean not), avec le vecteur de Stokes S(Boolean not). En conséquence S(Boolean not) est obtenu par la formule S(Boolean not) = A(Boolean not)-1 I(Boolean not). La matrice A(Boolean not) 4x4 de l'appareil doit être non singulière, ce qui implique que les plans d'incidence de chacun des faisceaux lumineux soient tous différents. Pour un agencement donné de quatre photodétecteurs, A(Boolean not) peut être soit calculé soit déterminé par étalonnage.

Abstract: Between the central equipment (ZE) and a terminal equipment (E1) connected to it, information items are alternately transmitted. The binary values can be formed by a lowering of the current or by the closed-circuit current value of the signal line. For the information items to be transmitted in the opposite direction, a voltage modulation can be provided. In the modem existing in the central equipment (ZSt), a weighting of the binary characters independent of the choice of current values is carried out for the evaluation of the binary characters formed via the current modulation. Thus, binary characters can be reliably decoded in any case, even if terminal equipments having a different mean current consumption are connected. To make this possible, a voltage comparator (K) is used, one input (x) of which is supplied with the voltage derived from the upper current value and at least approximately corresponding to this value and the other input (y) of which is supplied with the voltage corresponding to the instantaneous current value. Independently of the type of the respective terminal equipment, any change in the binary value then results in a corresponding change in the output signal of the voltage comparator. <IMAGE>

Abstract: The foldable partition for shower surrounds and the like consists of at least two adjacent wall elements which are connected to one another by a folding joint. A hinge pin is attached to each of the wall elements at the top and bottom side; two adjacent hinge pins are attached by a double joint strap. A sealing strip, which is attached to the outside of the one wall element and the inside of the other wall element, passes transversely through the hinge gap formed between the two wall elements. Seen in the axial direction of the folding joint, at least two sealing strips are provided which extend in opposite directions. When swivelled in any direction, the sealing strip is thus wound up at the abutting side of the one wall element and unwound at the abutting side of the other wall element so that the sealing strip alone adopts the function of that forced guide which ensures that, when the two wall elements are swivelled, the angle formed between each wall element and the double joint strap remains essentially the same. <IMAGE>

Abstract: A read only type optical disc, and disc drive apparatus for reading/additionally writing data into the disc. The disc has a recording material (7) formed in all of the tracks (6) by which data can be additionally recorded on the disc (l). This optical disc has a plurality of sectors (S0 - Sn) forming a data read-only area (4) and a write/read area (3). Each area has track sectors (S0 - Sn) each having a sector identifier portion (ID) in which address information is recorded and a data field portion (DF) to record data. Datafield identification flags (F1, F2) indicative of the read-only area (4) and the write/read area (3) are recorded in the respective identifier portions. On reading or writing this optical disc, the data field identification flag is detected to identify (l6, 26, 28) the kind of related area i.e., read-only area or write/read area. Thus, it is possible to avoid (l8 - 22; 28, 34) erroneous recording of data into the read-only area. Upon reading operation, waveform equalization and binary-clipping level of reproduction signals can be well controlled (26, 37, 39). The gain of the servo loop can be switched (53, 54). The track searching operation can be stably performed (58 - 63). The data reading and data writing into the data write/read area can be improved.

Abstract: An active acoustic attenuation system is provided that actively models direct and feedback paths as well as characteristics of the secondary cancelling sound source and the error path on an on-line basis. The primary model uses a recursive least mean squares RLMS algorithm that is excited by the input acoustic noise and uses the residual acoustic noise as an error signal. The secondary sound source or cancelling speaker and the error path are modeled by a second algorithm, particularly an LMS algorithm, that uses an additional auxiliary low level, random, uncorrelated noise source as an input signal. The resulting overall system provides excellent attenuation of narrow band and broad band noise over a relatively wide frequency range on a completely adaptive basis without directional transducers.

Abstract: Le but de l'invention est de réaliser un télescope à réflecteur composé d'un tube (2) agencé à l'intérieur d'un logement sphérique (1) et d'une calotte de support (4) dans laquelle est monté le logement sphérique (1). Dans un télescope à réflecteur connu, le tube peut être mis en rotation autour de son axe polaire et de son axe de déclinaison, ce qui requiert deux systèmes différents d'entraînement. En outre, l'accès au logement sphérique se modifie selon la position de celui-ci. Afin d'éviter ces inconvénients, le logement sphérique (1) est rotativement monté autour d'un axe horizontal (8) à l'intérieur de la calotte de support (4) et celle-ci est rotativement montée autour d'un axe vertical (50) dans une charpente de base (5), ce qui assure un accès stationnaire continu au logement sphérique (1), donc au tube (2). En outre, l'entraînement du logement sphérique (1) peut être très facilement construit.

Abstract: Known supporting and pull-out devices have a multiplicity of individual parts for pulling out the two plates, with the result that the device is of complex construction. Furthermore, the individual parts are visible from the outside and thereby exposed to the risk of soiling and damage. In order to simplify the design of the device and to protect the individual parts optimally, the plates (1, 2) are provided on their two side edges (21', 48) with a panelling (9, 28, 28'), which panellings are in engagement via a carrier (27). When the one plate (1) is pushed in and pulled out, its panelling (9) interacts with a lifting member (8') of the device. The panelling (9, 28, 28') of the two plates (1, 2) fulfils several functions since a positive connection of the plates (1, 2) is achieved due to both panellings (9, 28, 28') when the plates (1, 2) are pulled out. At the same time, the panelling (9, 9') of the one plate (1) serves for lifting and lowering said plate (1). The panellings (9, 28, 28') also protect the plates (1, 2) from wear and damage and allow a constructionally simple design of the device from few individual parts. <IMAGE>

Abstract: A drill for performing a roughing cut in a workpiece as the drill is advanced, and performing a finishing cut as the drill is retracted. A blade carrier is mounted eccentrically on the drill to be movable between first and second positions. In the first position, the blade is located for a roughing cut. In the second position, the blade is shifted radially for a finishing cut. A spring biases the carrier toward the second position and yields when the carrier moves to the first position. The spring bias is too weak to overcome reaction forces acting on the blade during a roughing cut, wherein the roughing cut reaction forces cause the carrier to be shifted to the first (roughing cut) position. The spring bias is strong enough to overcome the weaker reaction forces occurring during a finishing cut, so that the carrier is automatically shifted to the second (finishing cut) position when the drill is withdrawn through the workpiece. Thus, the blade is automatically shifted from the roughing-cut position to the finishing-cut in response to the initiation of a movement of the tool in a direction of withdrawal through the roughly cut hole.

Granted: 1992-05-20
Abstract: Process and corresponding apparatus, in the form of a swing frame for centring and securing the plate-shaped head (101) during repairs to mis-shapen rim drillings. The process involves making circular cutouts in the crown of the straight section (102) of the plate-shaped head, carrying out peripheral conical shaping on both sides and making the new crown plate (109). The rim is then centred and secured by support elements (13) to the swing frame by means of a conical pusher (27) clamped to the thread shoulder (2). The new crown plate is secured between the section support and the plate-shaped pusher before welding. Said support and pusher are height-adjusted on the thread shoulder. The rim is centred and clamped in a tilted position to the frame with a shortened thread shoulder. End welding, grinding to tolerances, making of holes and conical hole reaming may be carried out on the tilted frame or on the shortened thread shoulder frame, according to the rim position. In the positions envisaged, the rim is always secured centrally, the rim repair thus allowing the same properties to be achieved as in a new, industrially produced rim.

Abstract: Point and area target tracking are employed by a dual mode video tracker which includes both a correlation processor (30) and a centroid processor (32) for processing incoming video signals representing the target scene (20) and for generating tracking error signals over an entire video frame. A microcomputer (26) controls the operation of the correlation and centroid processors, as well as a preprocessor (28) which preconditions the incoming video signals. The tracker operates in any of several modes in which the correlation and centroid processors function either independently or cooperatively with each other. The correlation processor generates a reference map in pixel format which is used to produce azimuth and elevation optimal weighting values for each pixel in the field-of-view. The reference map is recursively updated. The track gate for the correlation processor is automatically sized using a gradient function derived from the optimal weighting values. The gradient function is also employed along with difference video to determine correlation tracking status. The correlation and centroid tracking errors may be combined to form a composite signal defining a true complementary function.
