Abstract: Un dispositif de commande de la polarisation comprend au moins une pile de cellules nématiques de cristaux liquides (1, 3) agencées de telle sorte que le rayonnement (101) incident sur la pile traverse successivement toutes les cellules de la pile. Des champs magnétiques ou électriques synchronisés sont appliqués aux cellules de façon à modifier d'une quantité sélectionnée le ralentissement de phase du rayonnement transmis à travers chaque cellule. Les axes optiques (5, 7) des cellules sont orientés les uns par rapport aux autres de sorte que le dispositif de commande provoque le changement de la polarisation du rayonnement incident sur le dispositif de commande d'un premier à un deuxième état.

Inventor: SCHIEL CHRISTIAN
IPC: D21F3/04
Filed: 1988-04-12
Abstract: In a papermaking machine, the wire section (10-12) is followed immediately by a first longitudinal-gap press (20) in which a flat press gap is formed between a press roller (22) and a flexible press tube (23). The press gap can be pressed against the press roller (22) by a press shoe (24). The press roller (22) is located below the flexible press tube (23) so that the action of the press shoe (24) is directed vertically downwards. The fibrous material web (9) from which the water is to be extracted runs, together with an upper felt (13) and a lower felt (15), on a linear running section at a slight upward inclination to the wire section in the direction of the press gap of the first longitudinal-gap press (20). Behind this first longitudinal-gap press (20) is a second longitudinal-gap press (30), in which the press roller (32) is arranged above the flexible press tube (33) so that the action of the press shoe (34) is directed vertically upwards.

Abstract: A ferrohydrostatic separator comprises a magnetic system (1) with two poles (N-S), the profile of which is designed so as to form a magnetic field of an intensity (H) varying over the height of the magnetic gap from the maximum value at the lower part of the poles to the minimum value at their upper part, a reservoir (2) made of a non-magnetic material and filled with a ferromagnetic liquid (3), as well as a device (4) for feeding the mechanical mixture of non-magnetic materials and a device (5) for removing the separated particles of the mechanical mixture. In the gap (N-S) between the poles are placed elements of ferromagnetic material forming local magnetic fields inside the column of the ferromagnetic liquid (3). The vector of the magnetic force (F1x) of each of the local magnetic fields is directed at an angle to the velocity vector (V) of particle movement in the mechanical mixture.

Abstract: The invention relates to a luminous source (2) for a device showing a flat image (14) through an angle of 360 DEG . The image (14) should in this case be visible with a continuous light intensity, independently of the speed of rotation. Thus, according to the invention, the variation of the light flux from the light source (2) may in the extreme case - as a function of the speed of rotation - reach a level which cannot be perceived by the human vision system. The inertia of the human vision system is utilised where during each complete rotation of the image carrier (10) through 360 DEG  the temporal sum of all bright phases amounts to at least 30%, preferably at least 50%, especially at least 70% of the time of a rotation of the image carrier (10), and/or where the frequency of the bright phases amounts to at least 200, preferably at least 600, especially at least 6000 Hz; in this case, preferably, the bright phases emit at least 75%, especially at least 90%, of the maximum light intensity. …<IMAGE>…

Title: Yarn splicing head
Inventor: ROSEN KLAUS
IPC: B65H69/06
Filed: 1990-02-02
Abstract: To join two yarn ends of textile staple yarns, at the present time it is customary to splice with compressed air in a yarn-splicing device. For this, the yarn ends are inserted into a yarn-splicing channel which is made in a yarn-splicing head. It has been shown that the surface of the splicing channel has an appreciable influence on the splicing result. To make it possible, with splicing channels (6), to ensure a reproducible predetermined quality of the surface, it is proposed that the splicing channel (6) be formed by a ceramic insert (7). The splicing head (2) has a recess (8) matched to the ceramic insert (7), and the ceramic insert is fitted into this recess. The surface quality of the splicing channels (6) can thereby be reproduced in an easily predeterminable way. <IMAGE>

Abstract: Situated in the end face (2, 2') of a cylindrical support (1) made of insulating material are four concentric metal rings to be used as electrodes (E1 to E4) for a conductimetry transducer. The rings are flush with the end face (2, 2'). The transducer can therefore be inserted into conductors or containers so as to be flush with the inside surface of their walls. If the electrodes are designed as hollow cylindrical metal rings of small overall height which are arranged coaxially with the centre axis of the support, the end face of the transducer can be of concave construction and matched to the curvature of the wall surface of a container. The invention is used in transducers for conductimetry. <IMAGE>
