Patent EP-0597627-A1 (EP)
Inventor: BLYLER JR LEE LANDIS
IPC: C03C25/10
Filed: 1993-11-04
Abstract: An optical transmission medium in accordance with the present invention comprises a substrate material (21) and a coating system (25) which at least partially encloses the substrate material. The present invention addresses the unexpected and beneficial enhancement of the strength retention capabilities of an optical transmission medium experienced when a coating system (25) provides a high quality interface between the coating and the optical transmission medium. The coating system (25) comprises a curable material. Also included in the coating system (25) is a component in the form of an adhesion promoter capable of enhancing the strength retention characteristics of the optical substrate material. In the preferred embodiment of the present invention, the particular adhesion promoter component includes an alkoxy silane containing at least one organic substituent carrying at least one mercaptyl hydrogen atom capable of reacting by Michael addition. Furthermore, the alkoxy silane may be gamma-mercaptopropyltrimethoxysilane and preferably comprises from about 0.5% to about 5% of the coating system.
Patent EP-0630877-A1 (EP)
Inventor: FUKUMOTO TAKEHIKO
IPC: C07C29/86
Filed: 1993-06-21
Abstract: An improvement is proposed for the removal of the precipitates of a phosphine oxide compound as a by-product from a mixture thereof with an olefin compound obtained by the Wittig reaction for the preparation of the olefin compound from a phosphorane compound and a carbonyl compound. Instead of the conventional procedure of filtration to remove the precipitates, the mixture in a hydrocarbon solvent, after replacement of a non-hydrocarbon solvent with a hydrocarbon solvent, if necessary, is admixed with a lower carboxylic acid such as acetic acid so that the precipitates of the phosphine oxide are dissolved forming a viscous fluid which is immiscible with the mixture of the olefin compound and the hydrocarbon solvent. The fluid containing the dissolved phosphine oxide compound can be easily removed by phase separation so that a great increase is obtained in the yield of the desired olefin compound.
Patent EP-0570331-A1 (EP)
Inventor: MUELLER-GLAUSER WERNER
IPC: A61L33/00
Filed: 1993-04-22
Abstract: The method according to the invention represents an improvement of methods known per se for making prostheses which consist of a preshaped synthetic carrier in whose surface region endogenous cells and cell assemblages are embedded and, after the implantation, initiate a coating of the prosthesis surface or of parts of this surface with a living layer. It has emerged that even if the cells and cell assemblages to be embedded originate from a tissue which, besides these cells, also contains other cells and non-cellular tissue components, isolation of the required cells before embedding is unnecessary. For this reason it is possible according to the method according to the invention to dispense with a complicated and lengthy processing of the tissue material used to isolate the required cells, as is described for corresponding methods according to the state of the art. The tissue material is reduced in size, essentially mechanically and, if necessary, additionally enzymatically, to tissue particles whose dimensions are within limits which are as narrow as possible, and is suspended, and the preformed carrier material is treated with the suspension by the suspension being filtered through the material in the case of porous carrier material and the suspension being brought onto the surface of the carrier material by centrifugation in the case of carrier material of little or no porosity. In contrast to corresponding methods according to the state of the art, the method according to the invention can, thanks to the improvement, be carried out in very little time, that is to say directly during the operation and in a closed system.

Title: Montage d'une turbomachine axiale
Inventor: MAANSSON MARTIN
IPC: F04D29/64
Filed: 1993-03-30
Abstract: L'invention concerne un procédé et un dispositif permettant de monter une turbomachine axiale, de préférence un compresseur à basse pression destiné à une turbine à gaz, construite sans ligne de joint et dotée d'un rotor monobloc ou assemblé. Du point de vue de la conception, des problèmes surgissent pour le montage des couronnes à pales des guidage stationnaires lorsque'on choisit une conception sans ligne de joint avec un rotor monobloc. On résoud ces problèmes en divisant ces couronnes à pales de guidage en plus de deux secteurs. On amène ces secteurs en position radiale et on les guide puis on les fixe à la position appropriée grâce à des anneaux de guidage qui sont appliqués autour de chaque couronne à pales de guidage composée de secteurs. Chaque couronne ainsi composée, dotée de l'anneau de guidage qui l'entoure, est guidée de manière à être fixée à l'anneau de guidage précédent et toutes les couronnes à pales de guidage sont construites successivement autour du rotor monobloc ou assemblé. Ces anneaux de guidage montés ensemble constituent un élément annulaire rigide.

Abstract: The sharply inclined transport surface of a slat conveyor is divided into an individual conveyance surface section and a sliding surface section; and a support plate in said individual conveyance surface section supporting only one rubber tire laid flat on said individual conveyance surface section is mounted at a larger pitch in the direction of transport than the maximum diameter of the rubber tire being conveyed. A mixed-suspended state collapsing member is mounted on a frame of said slat conveyor so as to project toward said rubber tire sliding surface section. Not only is a single rubber tire separated and carried out by a support plate but also a plurality of tires not supported by the support plate but being carried upward together in the sharply inclined individual transport zone of the slat conveyor may be raised by the mixed-suspended state collapsing member which is fixedly mounted protrusively on the sliding surface section, and securely returned to the horizontal take-in zone. Therefore, in the horizontal discharge zone, the individual separation-transport apparatus can discharge the rubber tires one by one, displaying a further great effect of individual separation and transport of the rubber tires in a lump which are otherwise not easy to separate because of a great surface friction coefficient.
