Abstract: A pipe connection for thin-walled, small-diameter metal pipes, in particular for braking lines, for fuel lines, and for hydraulic lines for motor vehicles, is provided with a sleeve (3) into which is sealingly set at least one first conically flared metal pipe (1) (so-called flare according to ISO 4038) in a bore cone (25) under the compression force of a tensioning body (8, respectively, 9) resting against the flare (23). In order to provide a pipe connection without screw parts and taking into account the narrow assembly or mounting quarters and in order to achieve a satisfactory sealing effect for the full duration of the operation of the connection, it is proposed to employ a sleeve (12) with an axially fixed annular channel (18). A radially partially thin-walled pressure bushing (15) is shifted onto the first metal pipe (1) up to resting at the flare (23). The pressure force of the flare (23) against the sealing seat (14) in axial direction is generated by a set deformation zone (20) of the pressure bushing (15), where the thin wall (21) is deformable into the axially fixed annular channel (18) of the sleeve (12) by an axial upsetting of the pressure bushing (15) into the sleeve (12).

Abstract: Une servo-direction comprend une soupape de distribution rotative composée d'un distributeur rotatif (10) formant une seule pièce avec la colonne de direction (3) et d'une douille de soupape (20) formant une seule pièce avec une tige filetée (5). Pour évacuer l'huile de retour pour chaque sens de rotation, des alésages de retour (11-17) sont longitudinalement agencés les uns derrière les autres, formant deux rangées adjacentes d'alésages (9 ou 9A). Chaque rangée d'alésages (9 ou 9A) est associée à une gorge de commande (24 ou 22) ménagée dans la douille de soupape (20) et reliée au cylindre moteur. L'alésage de retour (17) se situe entre les deux rangées d'alésages (9 ou 9A) et a une section transversale résiduelle immuable. Afin de réguler l'augmentation de la pression, tous les alésages de retour ont dans leur chambre de pression active (30 ou 31) des fenêtres plates de commande (51-57) ayant des longueurs circonférentielles diverses. La section transversale de retour créée par les alésages de retour peut être modifiée par un piston de commande (60) agencé dans un alésage concentrique (45) du distributeur rotatif (10). Le piston de commande (60) peut être ajusté en fonction d'une pression dépendant de la vitesse de conduite. Grâce à la modification de la section transversale de la rangée d'alésages (par exemple 9) qui participe à la commande de la pression, on obtient des forces d'actionnement du volant adaptées aux conditions de conduite.

Abstract: A decoding method of Reed-Solomon code produces an error polynomial (x) and an error evaluation polynomial  (x) by a Euclidean algorithm, whereby a syndrome polynomial S(x) is obtained, the highest degrees of the syndrome polynomial S(x) and of an initial polynomial x<2t>, which is determined by the number t of symbols to be corrected, are multiplied, while the degree is incrementally reduced, thereby obtaining polynomials h(x) and g(x) that satisfy the relation:      f(x) B(x) + g(x) S(x) = h(x) (where the degree of h(x) is less than the degree of g(x)</= t). The polynomial g(x) is set to the error position polynomial  (x), and the polynomial H(x) is set to the error evaluation polynomial  (x), thereby performing the decoding by real time processing.

Title: System for producing dithered images from continuous-tone image data
IPC: H04N1/40
Filed: 1988-03-09
Granted: 1992-04-29
Abstract: A digital image processing system for converting continuous tone pixel values representing an image into halftone or dithered pixel values, with the dithered pixel values representing each pixel having fewer bits than are used to represent each pixel in the continuous tone image. The continuous tone pixel for a line of pixels is loaded into an input buffer circuit having a plurality of storage locations, with each location storing the continuous-tone values for one pixel. Iteratively, the pixel value from each location is modified by a perturbed weighted error value, and then quantized to form the output halftone or dithered pixel value. An error value is then determined which is used in processing of subsequent continuous tone pixel values. The processing of the continuous tone pixel values procedes in a serpentine manner over the image, that is, processing of adjacent lines of the continuous tone pixel data proceeds in opposite directions.

Title: Tablet for use in the treatment of progesterone deficiency
IPC: A61K31/56
Filed: 1988-10-03
Granted: 1992-09-02
Abstract: A tablet comprises micronized progesterone blended with carnuba wax and safflower oil that produces sustained serum level increases of progesterone. The concentration of the wax is between 20 % and 150 % by weight of that of the progesterone. The particle size of the progesterone is largely below 10 microns. By thoroughly blending micronized natural progesterone with a wax having a melting point above body temperature, such as carnuba wax, degradation of the progesterone by the liver is sufficiently limited so as to achieve good serum level increases in progesterone on a sustained and substantially predictable basis. The inclusion of a limited quantity of safflower oil has also been found to be beneficial in this regard.

Abstract: A new type of a semiconductor material is disclosed which consists of a beta-SiC:metal carbide alloy having the general formula Siw(metal 1)x(metal 2)y(metal 3)z C, where w+x+y+z = 1 and 1>w>0. The metals are selected from the group consisting of Ti, Hf, Zr, V, Ta, Mo, W and Nb, with Ti, Hf, and Zr preferred. By selecting appropriate proportions of metal carbide and SiC, the alloy's bandgap may be tailored to any desired level between the bandgaps of the metal carbide and SiC. Semiconductor devices are preferably formed by epitaxially growing a layer of the new alloy upon a substrate (6) having a beta-SiC or TiC type crystal structure. In addition to retaining the benefits of single-bandgap beta-SiC with certain advantages, the new alloys make it possible to implement various electrical devices that cannot be achieved with beta-SiC, and also have a potential for bandfolded superlattices for infrared detectors and lasers.

Abstract: A method for regulation of the transverse distribution of the fibre orientation of a web produced by means of a paper machine or equivalent by regulating the transverse profile of the discharge opening (16) of the headbox (10) of the paper machine. The transverse grammage profile of the paper web (W0...W1) produced by means of the paper machine is measured, and the measurement signal obtained in this way is used as a feedback signal in the control system. With the machine configuration and parameters present in the paper machine to be controlled, data are collected concerning the relationship between the directional angle of the transverse distribution of fibre orientation and the transverse distribution of grammage of the web (W0...W1) that is being produced by, by means of the paper machine, carrying out response runs in its various states of operation (i). The relation data are stored in the memory of the computer (52). By making use of the relation data, the distribution of fibre orientation in the web (W0...W1) to be produced is corrected by regulating the transverse profile of the discharge opening (16) of the headbox (10). Moreover, a corresponding method for on-line measurement of the fibre orientation is described.

Compared to known procedures with other solubilizers, for instance isopropanol, in this case polyesters are produced with higher molecular weights. The acetone or methylethylketone also may simultaneously serve as precipitant after the end of polycondensation for the polymer dissolved in the organic liquid phase. The different solvents then employed in the process, for instance water, acetone and the chlorinated hydrocarbon may be separated by rectification and be used again.

Abstract: Un procédé pour réduire l'alimentation en carburant d'un cylindre dans un moteur à combustion interne polycylindrique à injection centrale consiste à fournir au cylindre qui précède, dans la suite de la course d'admission, le cylindre dont il s'agit de raréfier le mélange (par exemple parce que la combustion ne se fait pas) moins de carburant que lorsque tous les cylindres sont opérationnels. De plus, on ne fournit à la course d'admission pour le cylindre défaillant que le moins possible de carburant. Ce procédé permet d'obtenir un mélange très pauvre dans le cylindre défaillant, mais de régler la valeur lambda du mélange sur une valeur proche de 1 pour les autres cylindres. Grâce à ce procédé, le véhicule fonctionne de manière plus sûre et sans danger de surchauffe du catalyseur puisque le moteur à combustion interne fonctionne avec le cylindre défaillant.
