IPC: G01N33/544
Filed: 1989-10-05
Abstract: Est décrit un vecteur immunoréactif renfermant un élément antigène ou anticorps d'une seule paire de liaison liée par covalence à un milieu biocompatible contenant un gel protéinique ou un polysaccharide enrobant la surface d'un corps vecteur. Est également décrit un procédé de production de ce vecteur immunoréactif. Dans les cas où le milieu biocompatible est un gel protéinique, il est enrobé sur la surface du corps vecteur par interaction hydrophobe ou liaison covalente. Dans le cas où le milieu biocompatible est un polysaccharide, il est enrobé sur la surface du vecteur par liaison covalente. Le vecteur immunoréactif s'utilise dans un dosage mettant en oeuvre un élément d'une seule paire de liaison, tel qu'un antigène ou un anticorps d'une seule paire de liaison dans un échantillon biologique.

Abstract: On parvient à effectuer des transferts d'énergie améliorés entre des faisceaux optiques (10, 12) en opérant à des longueurs d'ondes se trouvant dans la région d'interbande d'une matière photoréfractive, et en employant un effet électroréfractif proposé antérieurement uniquement pour des faisceaux individuels. On applique un champ électrique dans un milieu photoréfractif (4) d'intensité suffisante pour induire un couplage électroréfractif puis un transfert d'énergie entre les faisceaux (10, 12). Des améliorations de gains sont possibles par orientation du milieu photoréfractif (4) afin d'obtenir un effet électro-optique et électroréfractif, et à l'aide d'une technique de réseau mobile. Le sens du transfert d'énergie entre les faisceaux est régulé par le sens du champ électrique, et peut être inversé par inversion du champ (18). Un fonctionnement dans la région de l'infrarouge est rendu possible à l'aide de matières semi-isolantes. On compte parmi les applications les commutateurs, les amplificateurs et les dispositifs de conjugaison de phases optiques.

Abstract: To monitor the traction force of a yarn, an average value is continuously formed. A check is made to ensure that the continuous measured value does not exceed the upper limit and a lower limit which varies with the average value, and that the average value does not go beyond specific limits. At the same time, a regulation of the yarn tension is carried out by entering the yarn tension in the false-twist transmitter (6) via a time filter (11), in such a way that a control of the frictional force takes place. The regulating signal forms said average-value signal. …<IMAGE>…

Inventor: BERGMANN ERICH
IPC: B22D30/00
Filed: 1991-03-01
Abstract: The device for supporting and cooling bearing shell blanks (2) arranged side by side during a coating process in a vacuum chamber has mutually releasable pairs of cooling bodies and workpiece supports (3), which are joined to one another via a cooling surface (9) and a heat transfer surface (7). The workpiece support part (5) of the pairs of cooling bodies and workpiece supports (3) is designed in such a way that the bearing shell blanks (2) inserted into its concave support surface (32) are held on their entire surface during the coating process at a temperature given by the cooling surface temperature; a temperature gradient can be generated if, onto the support surface, Teflon film strips are laid which allow only direct heat contact of the apex of the bearing shell blanks (2) with the support surface. Fine particles of high surface hardness are then deposited on the apex, and coarse particles having a correspondingly lower surface hardness are deposited on the edges. 
<??>During coating, workpiece support parts (5) can already be fitted, whereby the passage time in the manufacture of bearing shells (2) is considerably shortened. The low weight of the workpiece support part (5) has proved to be an advantage.

IPC: D03D47/30
Filed: 1991-03-09
Abstract: What is described is a method for controlling the weft insertion on air-jet looms, according to which, after a starting signal from an electronic control, the weft insertion via a main nozzle into the shed is initiated by means of a gaseous medium supplied from a first pressure source. The object on which the invention is based is to compensate differences in the weft flight times of successive weft-insertion cycles, without making a change to the weft-insertion parameters critical for the main acceleration phase. 
<??>For this, a first acceleration of the weft yarn takes place in a first acceleration phase, and thereupon the weft yarn experiences a further acceleration in a second acceleration phase, the moment for commencing the further acceleration being made dependent on the result of a desired-value/actual-value comparison of the yarn flight time over the weaving width.

Abstract: The method for controlling a positioning system, for example of an industrial robot, relates to constant-speed grinding of movement blocks. In this case, an auxiliary system of cartesian coordinates (XH, YH, ZH) is defined in the grinding zone, and the orientation (R1, R2, R3) of a robot tool (W) is interpolated relative to this auxiliary coordinate system via the roll, pitch and yaw angles. The auxiliary coordinate system is selected such that the RPY angles B1, B2, A1 have the value 0 at the grinding points (UP1, UP2). …<IMAGE>…

Abstract: The device comprises a pair of rollers (6, 7) limiting two sides of a rectangular measuring space (3) which is closed on three sides and on the fourth side of which is arranged a measuring member (5) for the thickness or unevenness of the sliver. The third side of the measuring space (3) is closed off by a guide roller (8) or by a guide plate, and the rollers (6, 7) serve for compacting the sliver in the measuring space. The measuring member (5) is formed by a leaf spring equipped with strain gauges. 
<??>As a result, on the one hand, the measuring accuracy of known devices rises because the sliver is driven actively at the measuring point, thus leading to an increase in the compaction of the sliver and therefore to an increase in the measuring accuracy dependent on the compaction, and, on the other hand, the inertia of the measuring member is very low.

Abstract: A vibration damping (2) device for skis (1) including a rigid plate (3) for supporting ski boot binding means (4,5) and having at least two holes (6a, 6b) which act as seats for at least one rigid spacer (7, 107, 207). At least one resilient member (9, 114, 117, 214, 217) is arranged coaxially to the rigid spacer, and the spacer interacts with a screw for interconnection with the ski and for supporting the resilient member. The resilient member has a washer (10) for supporting the rigid plate. The device thus allows the optimum damping of the vibrations which occur along an axis which is vertical with respect to the ski, without altering the possibility of transmitting the efforts imparted along different axes.

Abstract: A sealing device for valves is proposed, which has at least one sealing ring (13). The sealing ring (13) has a multi-piece housing ring (14), which is fixedly joined together and has an essentially U-shaped cross-section. Fixed in a radially resilient manner in the annular space (15) of the housing ring (14) is a single, integral sealing element (20) which, together with the housing ring (14), forms a component which can be handled as a unit. Said component projects with a sealing part (50) out of the housing opening (18) of the annular space (15). Sealing rings of this type can be fixed in valve housings in order to seal the valve housing with respect to the movable valve piston. The construction of the sealing rings allows assembly by robots.
