摘要:
Die Erfindung betrifft ein Leitungselement (10) für eine im Erdreich zu verlegende Leitung, mit wenigstens einem Endabschnitt (14), der mit einem benachbarten Leitungselement (12) verbindbar ist, und sich dadurch auszeichnet, dass der Endabschnitt (14) ein erstes Verbindungsmittel (16) aufweist, das mit einem zweiten Verbindungsmittel (18) in Eingriff bringbar ist, das an einem Endabschnitt (14) des benachbarten Leitungselements (12) ausgebildet ist. Hierzu ist erfindungsgemäß vorgesehen, dass der Endabschnitt (14) wenigstens abschnittsweise wenigstens eine Rippe an seiner Außenseite entlang des Umfangs aufweist, die mit einer dazu komplementär gestalteten Nut an der Innenseite entlang des Umfangs in Eingriff bringbar ist, das an einem Endabschnitt des benachbarten Leitungselements (12) ausgebildet ist.
摘要:
A rapid joining system (1) for joining elements of a chimney duct comprises elements which are connectable to one another to form a chimney duct; each element (2) extends along and about an axis (A) and comprises a male member (6) and a female member (7), arranged at opposite ends (3, 4) of the element (2) ; the male member (6) and the female member (7) comprise respective guide portions (11, 31), provided with respective series of projections (13, 33) inclined with respect to the axis (A) and cooperating for axially moving the male member (6) into the female member (7); the male member (6) comprises a conical portion (12), shaped so as to externally receive a connection portion (32) of the female member (7) and radially force said connection portion (32) upon the movement of the male member (6) into the female member (7).

A system and method for a valve for an expandable gas or fluid valve is disclosed. The valve comprises an electromagnetic switch with a male connector on one face, and a female connector on an opposite face. The electromagnetic switch has a passageway (1128) connecting the male connector with the female connector. An output port (1169) is switchably connected to the passageway (1128) by the electromagnetic switch. The male connector on one face can be coupled to the female connector on another electromagnetic switch, forming a line or chain of electromagnetic switches.

A lid (1110) for a reservoir (2) of a gravity feed spray gun (1) has an integral spout (1015; 1115) for direct connection to a socket (621) of the spray gun (1). The spout (1015; 1115) has a cylindrical portion (1080a) provided with a helical projection (1080d) for co-operating with a lug (686) on the spray gun (1) to secure releasably the lid (1110) to the spray gun (1). A stop in the form of an abutment at one end of the helical projection (1080d) is provided to limit rotation of the spout (1015; 1115) relative to the socket (621). The free end of the spout (1015; 1115) is received in the socket (621) and is provided with a sealing face (1080f).
摘要:
A securing means for securing together first and second members (11,11',111; 12,12',111), the first member (11,11',111) being elongate and having a generally central longitudinal axis (AI,AI'), the second member (12,12',112) having a socket (16,16',116), a locking element (13,13',113) secured relative to or integral with the first member, the locking element having a first engagement surface (15,15',115) and being receivable in the socket (16,16',116), the surface, upon less than one revolution of the first member (11,11',111) aboutthe longitudinal axis (A',A1') relative to the second member (12,12',112), being urged into contact with a second engagement surface (22,22',156) of the socket to secure the first and second members together.
