Abstract: Un système d'interpolation produit une valeur interpolée en réponse à une valeur d'entrée. Ledit système d'interpolation comprend une mémoire (30, 32) de valeurs de fonctions comprenant une pluralité de tables (30, 32) de stockage de valeurs de fonction destinée à stocker des valeurs de fonction afin de modifier les valeurs de coordonées de domaines dans un domaine. Un générateur d'adresses (38) crée, en réponse à une valeur d'entrée, des signaux d'adresses identifiant des emplacements dans les tables de stockage de valeurs de fonction, afin de permettre à ces dernières de transmettre des valeurs de fonction en parallèle. Un interpolateur (36) reçoit des valeurs de fonction transmises en parallèle par les tables de stockage de valeurs de fonction ainsi que la valeur d'entrée, et produit en réponse à celles-ci la valeur interpolée.

Abstract: The combing machine possesses a tearing-off device (11, 12, 13, 16) having a pair of tearing-off rollers (11, 12) for tearing off combed-out fibre tufts from a gripper (6, 7, 8, 9, 10) movable to and fro. A pair of soldering rollers (13, 16) for soldering the torn-off fibre tufts to form a combed fleece is arranged after the pair of tearing-off rollers (11, 12) in the tearing-off direction. The soldering rollers (13, 16) are designed to clamp the combed fleece only during part of each to-and-fro movement of the gripper (6, 7, 8, 9, 10). One of the tearing-off rollers (11) and one of the soldering rollers (13) are mounted fixedly relative to the stand in the combing machine and are driven continuously at a constant speed. Since virtually no parts rotating to and fro or moved to and fro are therefore needed in the tearing-off device (11, 12, 13, 16), high working speeds are possible. <IMAGE>

Title: Process for preparing alkyl tert-alkyl ethers
Inventor: SIRCAR SHIVAJI
IPC: C07C43/04
Filed: 1991-03-22
Abstract: A process for preparing an alkyl- ter t-alkyl ether wherein an olefin having a double bond on a tertiary carbon atom and a primary alcohol are reacted in the presence of a catalyst under conditions sufficient to produce an azeotropic alcohol/ether/hydrocarbon mixture containing the alkyl- ter t-alkyl ether. The azeotropic alcohol/ether/ hydrocarbon mixture is subjected to a cyclic liquid phase adsorption process sequence to selectively remove the alcohol. The resulting non-azeotropic ether/hydrocarbon stream can then be easily separated by distillation to provide the desired alkyl- ter t-alkyl ether product and a hydrocarbon product. The cyclic adsorption process employed to separate the alcohol from the ether/hydrocarbon mixture comprises introducing the alcohol/ether/hydrocarbon mixture into a plurality of adsorption columns containing an alcohol selective adsorbent, wherein each respective adsorption column undergoes successive steps of adsorption and desorption.

Title: Ceiling support for curtain rod, in particular for shower curtains
Inventor: HUEBINGER JOHANNES
IPC: A47K3/38
Filed: 1991-04-08
Abstract: A ceiling support for a curtain rod or a curtain rod arrangement with one or more curtains, which may be fixed to resilient rings which each exhibit a slit, comprising a supporting tube and a ceiling fixing, is to be designed in such a way that it offers the opportunity of moving the curtain in any direction over the entire length of the rod or over the entire rod arrangement. This is achieved in that the supporting tube (8) or a bush (7) to take one end of the supporting tube (8) is part of a supporting angle piece (4) with a crosspiece (5) which is at least approximately horizontal. This crosspiece passes into a resilient clamp (6) into which the curtain rod or the curtain rod arrangement (1) may be clamped, the crosspiece (5) being no thicker than the width of its slit (3) which can be achieved by the resilience of the rings (2). <IMAGE>

Abstract: An optical heterodyne or homodyne receiver comprises an integrated optical component (140) in which the local oscillator beam and the signal beam are combined and simultaneously split into orthogonally polarized sub-beams. The optical component comprises a polarization-sensitive beam-splitting layer in a first face (141) and a second beam-splitting layer in a second face (142) which is perpendicular thereto. This second layer functions as a beam-combining element in the optical receiver and has two distinct portions (142a and 142b), one portion (142a) of which passes and reflects one state of polarization (s) to the desired extent and the other portion (142b) having this property for the other state of polarization (p).

IPC: G02B6/44

Abstract: The invention relates to a method, a device and a method for installing a cable in a tubular cable duct. In the method, the foremost end (3) of the cable (1) in the duct (10) and subsequent portions of the cable are first accelerated in a short time with continuous supply of further portions of cable from a torsion-free store. Then, from the instant a certain speed v is reached, the cable is maintained at a tension such that, at said speed and tension, centrifugal forces in bends and inwardly pulling components of tensioning forces in the cable compensate for one another at the position of said bends, the further portions of the cable being supplied at a supply speed such that the part of the cable already fed into the duct can continue to slide on the basis of its mass moment of inertia. The acceleration can be achieved by causing propelling forces to act on the cable upstream of the inlet end (10a) of the duct in conjunction with pulling forces which act at least on the foremost end (3) of the cable (1) in the duct. The magnitude of at least the propelling forces is controlled by adjusting to zero the net transverse force on the cable, in a bend (8; 51) in the cable located beyond the position where the propelling forces act upon the cable in the direction of movement of the cable. 
     Advantages are that much higher installation speeds and/or greater installation lengths in one go are possible.
