摘要:
Die Erfindung betrifft einen Leitungsverbinder (1) für Medienleitungen (4), bestehend aus einem Verbinderstück (2) mit einem Strömungskanal (12) und mit mindestens einem Anschlussabschnitt (4, 8) zur Anschlussverbindung mit einer Medienleitung (4) oder mit einem Aggregat und mit mindestens einem an den Anschlussabschnitt (4, 8) angrenzenden Übergangsabschnitt (6, 10). Um bei einem derartigen Leitungsverbinder zu erreichen, dass bei tiefen Temperaturen ein Gefrieren des jeweiligen Mediums im Verbinderbereich verhindert bzw. ein gefrorenes Medium aufgetaut werden kann, wird vorgeschlagen, dass Heizmittel (13) in einer den Strömungskanal (12) zumindest teilweise umschließenden Anordnung vorgesehen sind, wobei am Verbinderstück (2) ein Fixierteil (14) mit Elementen (16, 18) zur Führung und Fixierung der Heizmittel (13) angeordnet ist.

Methods and apparatus for positioning a structure on a polymer layer are described. A method may involve forming a first polymer layer. The method may further involve positioning, by an apparatus, a structure on the first polymer layer, where the apparatus comprises a rod having a first end that supports the structure as the structure is being positioned and a plunger located around the first end of the rod that presses the structure onto the first polymer layer as the structure is being positioned. And the method may involve forming a second polymer layer over the first polymer layer and the structure, where the first polymer layer defines a first side of a body-mountable device and the second polymer layer defines a second side of the body- mountable device opposite the first side.

Verfahren zur Herstellung eines Behälters umfassend: - Bereitstellen zweier bahnförmiger Vorformlinge (7), - Anlegen und Formen der Vorformlinge (7), - Ausstanzen oder Auskreisen wenigstens einer Öffnung (18) in wenigstens einem schalenförmigen Zwischenerzeugnis, wobei in einem zweiten Verfahrensschritt ein erstes Anschlusselement einer Leitungsverbindung oder einer Leitungsanordnung formnestseitig mit der Wand des schalenförmigen Zwischenerzeugnisses verschweißt wird, derart, dass ein umlaufender Schweißkragen (23) des ersten Anschlusselements die Öffnung (18) dichtend umschließt, - Fügen der schalenförmigen Zwischenerzeugnisse zu einem Behälter und Entnehmen des Behälters aus dem Blasformwerkzeug (1) sowie - Verbinden eines zweiten Anschlusselements (25), das mit dem ersten Anschlusselement im Sinne einer Steckverbindung komplementär ist, mit dem ersten Anschlusselement, wobei die Steckverbindung innerhalb der durch die Behälterwand definierte Kontur des Behälters hergestellt wird.
摘要:
Disclosed is a method and apparatus for covering the blade of a hockey stick. The blade has an exterior surface and a cross sectional area. The apparatus comprises a sleeve having first and second ends and an inner surface and an outer surface. The inner surface defines a cavity wherein the cavity has a cross sectional area which is less than the cross sectional area of the blade. The inner surface of the sleeve has an adhesive material thereon. The method comprises sliding the sleeve over the hockey blade and applying heat to the sleeve sufficient to melt the adhesive material so as to adhere the inner surface of the sleeve to the outer surface of the blade.
摘要:
A high-voltage composite insulator is substantially comprised of a rod (2) of synthetic material reinforced with fiber glass, screen forming bodies (3) and connection armatures (4). The outer cylindrical surfaces of the rod (2) of synthetic material reinforced with fiber glass are coded with a first layer (5) of silicon rubber and with a second layer (6) of synthetic plastic grease. The screen forming bodies (3) are crimped on said outer layer of the rod (2) of synthetic material. These screen forming bodies are made of polytetrafluoroethylen. They present in the direction of the longitudinal axis thereof smooth cylindrical bores (7). The diameter of these bores (7) is very slightly smaller than the diameter of the rod (2) covered by said layers. The screen forming bodies (3) supported by the synthetic material rod (2) are heated before their mounting and then set on the rod (2). In order to prevent water or dirt from penetrating inside the screen forming bodies (3) threaded onto the synthetic material rod (2), these bodies are preferably assembled by a tongue and groove joint (9a and 9b).
摘要:
A too! for fixing a protective textile sleeve about an elongate member contained therein and method of use thereof is provided. The tool includes a clamp assembly having opposed clamp members attached to one another for pivotal movement relative to one another between an open state and a closed state. The clamp members have clamping surfaces, wherein at least one of the clamping surfaces has at least one outlet, A fluid source is arranged in fluid communication with the at least one outlet, and a heat source is configured to heat fluid from the fluid source to create steam. The steam is dispensed outwardly from the at least one outlet to cause an adhesive on the sleeve to become activated to bond with an adjacent abutting surface.

A puller having means for gripping a flexible fluid line and means for constricting the line thereby reducing its ability to pass fluid suitable for use in connection with a duct seal or cable splice case, including a flexible hollow member that can be inflated through the fluid line to seal a gap between first and second articles.
摘要:
A container (20) having a semi-rigid or rigid outer shell (22) and a co-extensive flexible inner liner (24) which is weakly or temporarily adhered to the shell (22) to permit more convenient manufacturing of the container (20) and yet is collapsible to permit dispensing of the contents (28) without displacement air, and an access site (58) defined in the container wall to which an access assembly (26) may be attached. The liner (24) may be weakly adhered to the shell (22) by a low tensile strength adhesive although natural adherence or static electric attraction may also be used. Alternatively, a degradable adhesive may be used which holds the liner (24) and shell (22) together during assembly, but weakens to a point below the threshold of release between the shell and the liner prior to the time of use. The access site (58) is preferably defined by an annular fold (60) in the container wall which tightly captures the liner (24) to provide a mechanical peripheral seal between the shell (22) and the liner (24) around the access site to prevent leakage of liquid, into the area between the shell (22) and the liner (24). The container (20) is particularly useful as a nursing container, including a nipple access site (58) with an attached nipple assembly (26).
