Abstract: A slip joint assembly for joining multiple pipes is provided. The slip joint assembly includes a flow expander that is connected to a downstream pipe and is tapered toward a forward end. An inlet bellmouth is coupled to the forward end of the flow expander and defines a flared inlet positioned within an upstream pipe. An annular seal assembly is coupled to the upstream pipe and includes a ball seal positioned around and forming a seal with the flow expander to operably couple the upstream pipe and the downstream pipe. An internal diameter of the annular seal assembly is smaller than a diameter of the flared inlet.

Abstract: An extendable and contractible flexible joint having a pair of flexible joint portions, which are bendable and fitted and connected to a connection sleeve, in a direction of a pipe axial line. An extending motion limiting portion includes a fluid chamber into which a portion of a pressure fluid in a flow path diverges and flows, and is configured to apply a fluid pressure applied to pressure receiving surfaces of the fluid chamber. An inner joint body of each of both the flexible joint portions is configured to be attachable and detachable to and from the connection sleeve, and an outer joint body and the inner joint body of each of both the flexible joint portions are configured to be attachable and detachable to and from each other.

Abstract: Provided is an apparatus for connecting two sub-flow systems (e.g. airplane fuel tanks) and conveying a fluid between the two sub-systems using a pressured balanced transfer tube, particularly when there are large radial and axial movements or offsets between the sub-systems. Unlike conventional fluid transfer systems, the present apparatus allows for the pressure in the transfer tube to be balanced to internalize the pressure forces and prevent the exertion of pressure forces on the sub-systems connected to the transfer tube.

Abstract: A pipe connecting system for providing fluid communication between pipes that are offset vertically and/or horizontally is described. The pipe connecting system comprises a first and second pivot attachment system for attaching the pipe connecting system to the pipes; and a telescopically extendable central connector that is pivotably engaged with the first and second pivot attachment systems to enable the central connector to be positioned at various angles with respect to the pivot attachment systems.

The central connecting portion has a telescopically extending connection where a flexing assembly allows for a prescribed amount of motion between the first and second pivot attachment assemblies.

Abstract: A dual walled transfer tube connecting two sub-flow systems and conveying the system fluid from one subsystem to another when there are large radial and axial movements or offsets between the connecting ends of the subsystem. The dual walled transfer tube has a fitting at either end and a single ball joint proximate each fitting to allow the transfer tube to accommodate changes in radial position of the fittings. The dual walled transfer tube utilizes a main inner fluid passage and an outer secondary fluid passage, each fluid passage having a slip joint to allow the transfer tube to accommodate changes in axial length between the fittings.

The second element extends through the conical bore for movement within the conical bore, and a threaded end structured and arranged to mate with the threaded portion of the first element. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A flexible pipe joint joins, in a bendable manner, a first pipe member provided with a partially spherical outer circumferential surface that protrudes outward in radial direction and a second pipe member provided with a partially spherical inner surface that can slide along the partially spherical outer circumferential surface. A sleeve made of a synthetic resin is inserted and fitted in a state of contact, bridging the inner circumferential surfaces of the two pipe members. The sleeve has a length that covers a cavity portion that opens inward in radial direction at a location where the two pipe members are joined together, and is elastically deformed substantially maintaining its circular tube shape when following a flexure of the two pipe members.

Abstract: The present invention relates to a device/connection which can be used e.g. in a vacuum cleaner pipe, which thereby can be made bendable to facilitate vacuum-cleaning under beds, tables and the like. I one simple operation a moveable part (5) can be displaced inwards, whereupon a locking pipe (6) prevents a bendable hose (2) from being bent when the operator so desires, for instance during cleaning of open surfaces without obstacles. Cleaning under beds can however cause the operator to redraw the locking pipe (6) with the moveable part (5), whereupon the vacuum cleaner pipe becomes bendable again and the operator can vacuum-clean under the bed in standing position.

Abstract: A watering wand allows for telescopic adjustment of its length. The wand includes a primary tube defining a hollow interior portion and a secondary tube slidably disposed within the primary tube. The primary tube includes a fitting for attaching the wand to a water source. The secondary tube includes a connector suitable for receiving a fluid dispensing nozzle. The secondary tube also defines a portion to allow fluid to pass between the water source and the connector. An adjustment collar attached to a distal end of the primary tube slidably engages the secondary and may be used to fix the position of the secondary tube relative to the primary tube. The connector may be attached to a ball and joint coupling to allow for a pivoting nozzle and a quick-connect coupling to allow for easily changing nozzles to meet various watering needs.
