КЛАПАННЫЙ УЗЕЛ И СПОСОБ ЕГО ИСПОЛЬЗОВАНИЯ

FIELD: processes. SUBSTANCE: group of inventions relates to valve manufacturing and is designed to shutoff a pipeline. Valve comprises a body with an outer perimeter which defines the outer surface of the valve and an inner perimeter which defines a flow path through the valve. Closure member and a seat are located within the inner perimeter of the valve body. Closure member is configured to selectively open and close the flow path. Seat is configured to interact with a portion of the closure member when the closure member is in a closed position to prevent flow through the flow path. Stem is configured to support the closure member in the flow path. Connector of the closure member and the stem is configured to connect and rotate the closure member and the stem. At the same time the closure member is movable relative to and independent of the stem along the longitudinal axis of the stem, preventing relative rotation of the stem. Method of using such a valve is provided. EFFECT: increased reliability of the valve, particularly in its vertical position. 17 cl, 12 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 586 959 C2 (51) МПК F16K 1/24 (2006.01) F16K 27/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2012151962/06, 13.05.2011 (24) Дата начала отсчета срока действия патента: 13.05.2011 Приоритет(ы): (30) Конвенционный приоритет: (72) Автор(ы): ДЖИНТ Дэвид (US), ДЕРНОВСЕК Джон (US), КАРЛСОН Дэрин (US), РЭЙМОНД Фрэнк (US) (43) Дата публикации заявки: 20.06.2014 Бюл. № 17 R U (73) Патентообладатель(и): Брэй Интернешнл, Инк.

Method to make structures of complex shape from composite materials

FIELD: technological processes. ^ SUBSTANCE: invention relates to a method to make a part of composite material, fibres of which are coated with polymer that changes from paste-like or fluid condition into solid state in process of hardening phase by means of heating. The manufactured part contains a partially closed zone, which fully or partially at least at some stages of the method is occupied with a core. The core comprises a chamber made of elastic material with outer surface that limits the volume of the core, shape and dimensions of which comply with the volume of the partially closed zone and has the inner surface that determines the chamber volume. The specified volume of the chamber is filled with elements of solid granulated material and intragranular medium. The elements of the solid granulated material are selected so that the solid granulated material has such coefficient of expansion, at which the core volume changes in a controlled manner so that core dimensions vary in the specified manner as temperature increases to harden the polymer. ^ EFFECT: elimination of flaking when making a part of a composite material, and also elimination of part dimensions increase during operation. ^ 17 cl, 7 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 433 045 (13) C2 (51) МПК B29C 70/44 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ Приоритет(ы): (30) Конвенционный приоритет: 20.03.2006 FR 0650956 (73) Патентообладатель(и): ЮРОПИАН АЭРОНОТИК ДЕФЕНС ЭНД СПЕЙС КОМПАНИ ЭАДС ФРАНС (FR) R U (24) Дата начала отсчета срока действия патента: 20.03.2007 (72) Автор(ы): КАВАЛЬЕР Фредерик (FR), ГИТТОН Морис (CA), ГИТТОН Северин (CA) (21)(22) Заявка: 2008141311/05, 20.03.2007 (43) Дата публикации заявки: 27.04.2010 Бюл. № 12 2 4 3 3 0 4 5 (45) Опубликовано: 10.11.2011 Бюл. № 31 (56) Список документов, цитированных в отчете о поиске: US 4292101 А, 29.09.1981.

METHOD FOR PRODUCING STRUCTURES OF COMPLEX SHAPES IN COMPOSITE MATERIALS

Pour réaliser une pièce en matériau composite dont la forme est dite non démoulable il est nécessaire de réaliser des éléments de moule dit noyaux qui doivent être extrait de la pièce après le durcissement du matériau composite.Le procédé consiste dans une première étape à réaliser un noyau à partir d'une vessie en élastomère dont la forme voulue est obtenue en remplissant la vessie avec un matériau solide granulaire et une mise en dépression de la vessie et dans une seconde étape, après la mise en place du noyau et du matériau composite a modifier de manière contrôlée le volume du noyau par exemple en sélectionnant le matériau solide granulaire pour ses propriétés de dilatation thermique ou en agissant sur la pression dans la vessie. To make a composite material part whose shape is called non-demoldable it is necessary to make mold elements said cores which must be extracted from the workpiece after hardening of the composite material.The method consists in a first step to achieve a core from an elastomer bladder whose desired shape is obtained by filling the bladder with a granular solid material and a bladder depression and in a second step, after the introduction of the core and the composite material to be modified in a controlled manner the volume of the core for example by selecting the granular solid material for its thermal expansion properties or by acting on the pressure in the bladder.

Automatic valve for decanted effluent biological purification systems e.g. sand filters, has lid articulated about axis that is provided parallel to axis of valve body, where lid is pressed against valve body

Dispositif de vanne automatique à opercule rotatif, fonctionnant sans énergie pour stocker une masse liquide puis la libérer à fort débit. Ce dispositif est particulièrement adapté pour la distribution d'effluent décanté vers les différents systèmes d'épuration biologiques tels que filtres à sable plantés ou non et filtres bactériens. Il se caractérise par l'utilisation d'un opercule tournant sur un axe, lui appliquant une force de contact avec l'extrémité du corps de vanne pour garantir l'étanchéité. L'opercule se dégage par une rotation engendrée par un bras articulé, muni d'un flotteur d'ouverture auquel il est relié, bras qui est retenu par une gâche puis libéré pour provoquer son déplacement.

Gas tap

Vehicle heating system water flow valve - has two armed coil spring acting on pivoted disc engaged with sealing ring (SW 2.5.77)

The valve is used to control the flow of hot water in a vehicle heating system. It has a casing in which is pivotally mounted a disc, the pivot axis being transverse to the direction of flow of the water. Between the valve disc and an operating lever mounting is mounted a spring with one arm received in a blind hole in the mounting. The spring has a second arm which bears in a recess in one face of the disc, and is coiled around an operator for the disc. The spring acts on the disc which abuts a sealing ring in the duct in which the disc operates.
